The APS journals receive manuscripts from scientists all over the world. For authors whose names cannot be expressed in Latin characters, their names in the byline must be transliterated, a process that is not necessarily bidirectionally unique. For example, the eight Chinese names all transliterate as Wei Wang. To remove some of the ambiguity arising from this unfortunate degeneracy of names, APS will allow some authors the option to include their names in their own language in parentheses after the transliterated name, such as Wei Wang. The option to present names in the article byline in this manner is an experiment initially offered to Chinese, Japanese, and Korean authors, whose names can be expressed in Unicode characters. An example of a Japanese name is Tadanori Minamisono and a Korean name is Chang Kee Jung. In the English text the given name precedes the family name, while the reverse is true for the characters. As we gain experience, we may be able to broaden this offer to other languages. Authors who wish to try this option will need to prepare their manuscripts by following the special instructions at http://authors.aps.org/names.html.

We report the genetic linkage map of Jian carp ( Cyprinus carpio var. Jian). An F1 population comprising 94 Jian carp individuals was mapped using 254 microsatellite markers. The genetic map spanned 1 381.592 cM and comprised 44 linkage groups, with an average marker distance of 6.58 cM. We identified eight quantitative trait loci (QTLs) for body weight (BW) in seven linkage groups, explaining 12.6% to 17.3% of the phenotypic variance. Comparative mapping was performed between Jian carp and mirror carp ( Cyprinus carpio L.), which both have 50 chromosomes. One hundred and ninety-eight Jian carp marker loci were found in common with the mirror carp map, with 186 (93.94%) showing synteny. All 44 Jian carp linkage groups could be one-to-one aligned to the 44 mirror carp linkage groups, mostly sharing two or more common loci. Three QTLs for BW in Jian carp were conserved in mirror carp. QTL comparison suggested that the QTL confidence interval in mirror carp was more precise than the homologous interval in Jian carp, which was contained within the QTL interval in Jian carp. The syntenic relationship and consensus QTLs between the two varieties provide a foundation for genomic research and genetic breeding in common carp.

This study aimed to investigate the effects of threonine (Thr) on the digestive and absorptive ability, proliferation and differentiation of enterocytes, and gene expression of juvenile Jian carp (Cyprinus carpio var. Jian). First, seven isonitrogenous diets containing graded levels of Thr (7.4–25.2 g/kg diet) were fed to the fishes for 60 days. Second, enterocyte proliferation and differentiation were assayed by culturing enterocytes with graded levels of Thr (0–275 mg/l) in vitro. Finally, enterocytes were cultured with 0 and 205 mg/l Thr to determine protein synthesis. The percent weight gain (PWG), specific growth rate, feed intake, feed efficiency, protein retention value, activities of trypsin, lipase and amylase, weights and protein contents of hepatopancreas and intestine, folds heights, activities of alkaline phosphatase (AKP), γ- glutamyl transpeptidase and Na+/K+-ATPase in all intestinal segments, glutamate-oxaloacetate transaminase (GOT) and glutamate-pyruvate transaminase (GPT) activities in hepatopancreas, and 4E-BP2 gene expression in muscle, hepatopancreas and intestinal segments were significantly enhanced by Thr (p<0.05). However, the plasma ammonia concentration and TOR gene expression decreased (p<0.05). In vitro, Thr supplement significantly increased cell numbers, protein content, the activities of GOT, GPT, AKP and Na+/K+-ATPase, and protein synthesis rate of enterocytes, and decreased LDH activity and ammonia content in cell medium (p<0.05). In conclusion, Thr improved growth, digestive and absorptive capacity, enterocyte proliferation and differentiation, and protein synthesis and regulated TOR and 4E-BP2 gene expression in juvenile Jian carp. The dietary Thr requirement of juvenile Jian carp was 16.25 g/kg diet (51.3 g/kg protein) based on quadratic regression analysis of PWG. PMID:23922879
Association study between single nucleotide polymorphisms in leptin and growth traits in Cyprinus carpio var. Jian.
Tang, Y; Li, H; Li, J; Yu, F; Yu, J
Leptin is a hormone that affects the regulation of body weight, energy expenditure, fat metabolism, food intake, and appetite. In this study, we cloned the jlLEP-A1 and jlLEP-A2 genes in Jian carp (Cyprinus carpio var. Jian) and performed an association analysis between identified polymorphisms and growth traits. Three polymorphisms in exons of jlLEP-A1 (A1-T113C) and jlLEP-A2 (A2-G415A and A2-G427A) were identified, and genotyped by the polymerase chain reaction - restriction fragment length polymorphism method in 263 female and 294 male Jian carp. All three SNPs were missense mutations. Association analysis revealed that the three SNPs were significantly associated with growth traits in male Jian carp. Only SNP A1-T113C was significantly associated with growth traits in female Jian carp. Analysis of diplotypes derived from jlLEP-A2 SNPs revealed an association with growth traits in male but not female Jian carp. These results demonstrate that polymorphisms in the leptin gene are associated with growth traits and may be used for marker-assisted selection programs in Jian carp breeding and production.

Soyabean glycinin depresses intestinal growth and function in juvenile Jian carp (Cyprinus carpio var Jian): protective effects of glutamine.
Jiang, Wei-Dan; Hu, Kai; Zhang, Jin-Xiu; Liu, Yang; Jiang, Jun; Wu, Pei; Zhao, Juan; Kuang, Sheng-Yao; Tang, Ling; Tang, Wu-Neng; Zhang, Yong-An; Zhou, Xiao-Qiu; Feng, Lin
This study investigated the effects of glycinin on the growth, intestinal oxidative status, tight junction components, cytokines and apoptosis signalling factors of fish. The results showed that an 80 g/kg diet of glycinin exposure for 42 d caused poor growth performance and depressed intestinal growth and function of juvenile Jian carp (Cyprinus carpio var. Jian). Meanwhile, dietary glycinin exposure induced increases in lipid peroxidation and protein oxidation; it caused reductions in superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) activities; and it increased MnSOD, CuZnSOD, GPx1b and GPx4a mRNA levels, suggesting an adaptive mechanism against stress in the intestines of fish. However, dietary glycinin exposure decreased both the activity and mRNA levels of nine isoforms of glutathione-S-transferase (GST) (α, μ, π, ρ, θ, κ, mGST1, mGST2 and mGST3), indicating toxicity to this enzyme activity and corresponding isoform gene expressions. In addition, glycinin exposure caused partial disruption of intestinal cell-cell tight junction components, disturbances of cytokines and induced apoptosis signalling in the distal intestines>mid intestines>proximal intestines of fish. Glycinin exposure also disturbed the mRNA levels of intestinal-related signalling factors Nrf2, Keap1a, Keap1b, eleven isoforms of protein kinase C and target of rapamycin/4E-BP. Interestingly, glutamine was observed to partially block those negative influences. In conclusion, this study indicates that dietary glycinin exposure causes intestinal oxidative damage and disruption of intestinal physical barriers and functions and reduces fish growth, but glutamine can reverse those negative effects in fish. This study provides some information on the mechanism of glycinin-induced negative effects. PMID:26349522

Results are presented for Wang-Landau calculations on a Heisenberg model of BCC Fe that describe the density of states as function defined for all accessible energies instead of a function tabulated at discrete values of the energy. The density of states function described here is an analytic result valid near the ground state supplemented by a polynomial expansion. The probability density of Wang-Landau random walkers is sampled for a fixed density of states, and that probability density can be used to improve the estimated density of states. Methods for evaluating the convergence of the density of states are discussed along with the diffusion behavior of the random walkers.

Hepatoprotective effects of a Chinese herbal formulation, Yingchen decoction, on olaquindox-induced hepatopancreas injury in Jian carp (Cyprinus carpio var. Jian).
Zhou, Jishu; Li, Chao; Wang, Lihong; Ji, Hong; Zhu, Tianhe
In order to identify effective hepatoprotective herbs for clinical application in fish farming, 200 mg/kg olaquindox (OLA) was added to a basal diet (group 1, control) to form OLA diet (group 2), then 1.35, 2.7 and 5.4 % (w/w) of a Chinese herbal formulation, Yingchen decoction (YCD), were added to the OLA diet to form three additional diets for groups 3, 4 and 5, respectively. A total of 375 juvenile Jian carp (Cyprinus carpio var. Jian) (52.12 ± 2.95 g/tail) were divided into five groups (triplicates per group) and fed the five diets mentioned above, respectively, for 6 weeks. At the termination of feeding experiment, serum biochemical indexes, viability of hepatocytes and the hepatopancreas microstructure for each group were detected and observed. The results showed that serum ALT and AST in group 2 were significantly higher than the control (P < 0.05). Plasma membranes hepatocyte nuclei in group 2 were found to be mostly indistinct, compared to group 1, and gradually recovered with the increasing supplementation of YCD in group 3, 4 and 5. The viability of isolated hepatocytes in group 2 was the lowest and gradually recovered with the increasing supplementation of YCD in group 3, 4 and 5. The results suggest that YCD protected the Jian carp hepatopancreas against injury from OLA, and that 5.4 % YCD would be the optimum dosage in a Jian carp diet. PMID:25477196
Identification and characterization of a LTR retrotransposon from the genome of Cyprinus carpio var. Jian.
Cao, Liping; Yin, Guojun; Cao, Zheming; Bing, Xuwen; Ding, Weidong
A Ty3/gypsy-retrotransposon-type transposon was found in the genome of the Jian carp (Cyprinus carpio var. Jian) in a previous study (unpublished), and was designated a JRE retrotransposon (Jian retrotransposon). The full-length JRE retrotransposon is 5126 bp, which includes two long terminal repeats of 470 bp at the 5' end and 453 bp at the 3' end, and two open reading frames between them: 4203 bp encoding the group-specific antigen (GAG) and polyprotein (POL). The pol gene has a typical Ty3/gypsy retrotransposon structure, and the gene order is protease, reverse transcriptase, RNase H, and integrase (PR-RT-RH-IN). A phylogenetic analysis of the pol gene showed that it has similarities of 40.7, 40, and 32.8 %, to retrotransposons of Azumapecten farreri, Mizuhopecten yessoensis, and Xiphophorus maculatus, respectively. Therefore, JRE might belong to the JULE retrotransposon family. The copy number of the JRE transposon in the genome of the Jian carp is 124, determined with real-time quantitative PCR. The mRNA of the JRE retrotransposon is expressed in five Jian carp tissues, the liver, kidney, blood, muscle, and gonad, and slightly higher in the kidney and liver than in the other tissues.

Communicating between the Apple and the Wang
Barton, G.W., Downey, R.
This manual covers what the beginner needs to know in order to transfer files between an Apple's Microcomputer and a Wang's OIS Word Processor. We have also tried to indicate where the experienced user might want to look for additional details. We cover the use of Apple Writer )(, VisiTerm, VisiCalc, and EasyWriter Professional. For us, the two most useful connections are from Applewriter to Wang and from Visicalc to Wang. From Wang to Apple Writer via Visiterm may have some value. Files can be transferred by VisiTerm to Wang, but they arrive with RETURNS in the middle of words, which have to be edited out, so we do not recommend it. We describe how to go from EasyWriter to Wang, but we do not know how to go from Wang to EasyWriter. We see no reason to go from Wang to VisiCalc, so we haven't thought about it. All instructions are given for a typical configuration of the Apple, namely the one on which this manual was composed. It is detailed in the section on Hardware and Software.
A Study of 2,3,7,8-Tetrachlorodibenzo-p-dioxin Induced Liver Injury in Jian Carp (Cyprinus carpio var. Jian) Using Precision-Cut Liver Slices.
Du, Jin-Liang; Cao, Li-Ping; Liu, Ying-Juan; Jia, Rui; Yin, Guo-Jun
The aim of this study was to establish a model for the study of liver injury induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in Jian carp using precision-cut liver slices (PCLS). PCLS were treated with TCDD at concentrations of 0, 0.05, 0.1, 0.3, and 0.6 μg/L for 6 h, followed by collection of the culture supernatant and PCLS for analysis. Several biochemical indices were analyzed, including glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), lactate dehydrogenase (LDH), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA). Expression of mRNA was also estimated for cytochrome P4501A (CYP1A), aryl hydrocarbon receptor2 (AhR2), and aryl hydrocarbon receptor nuclear translocator2 (ARNT2). Results showed that some significant effects (p < 0.05) in MDA, GSH-Px and PCLS viability were observed at a TCDD concentration as low as 0.05 µg/L, and the observed effects increased with exposure concentration. Following exposure to TCDD for 6 h at a concentration of 0.3 μg/L, significant increases (p < 0.01) in the content of GPT, GOT, MDA, and LDH were observed, while SOD activity, GSH-Px activity, and PCLS viability were decreased (p < 0.01 or p < 0.05). Exposure to 0.3 μg/L TCDD also resulted in increased expression of mRNA for CYP1A, AhR2, and ARNT2. Overall, these results provide evidence of TCDD-induced liver injury and oxidative stress in Jian carp. These results also support the use of PCLS as an in vitro model for the evaluation of hepatotoxicity in Jian carp. PMID:26508429

The present work evaluates the effects of various levels of dietary choline on antioxidant defenses and gene expressions of Nrf2 signaling molecule in spleen and head kidney of juvenile Jian carp (Cyprinus carpio var. Jian). Fish were fed with six different experimental diets containing graded levels of choline at 165 (choline-deficient control), 310, 607, 896, 1167 and 1820 mg kg(-1) diet for 65 days. At the end of the feeding trail, fish were challenged with Aeromonas hydrophila and mortalities were recorded over 17 days. Dietary choline significantly decreased malondialdehyde and protein carbonyl contents in spleen and head kidney. However, anti-superoxide anion and anti-hydroxyl radical activities in spleen and head kidney also decreased. Interestingly, activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST) and glutathione reductase (GR) in spleen, GPx activity in head kidney, and glutathione contents in spleen and head kidney were decreased with increase of dietary choline levels up to a certain point, whereas, activities of SOD, GST and GR in head kidney showed no significantly differences among groups. Similarly, expression levels of CuZnSOD, MnSOD, CAT, GPx1a, GPx1b and GR gene in spleen and head kidney were significantly lower in group with choline level of 607 mg kg(-1) diet than those in the choline-deficient group. The relative gene expressions of Nrf2 in head kidney and Keap1a in spleen and head kidney were decreased with increasing of dietary choline up to a certain point. However, the relative gene expression of Nrf2 in spleen were not significantly affected by dietary choline. In conclusion, dietary choline decreased the oxidant damage and regulated the antioxidant system in immune organs of juvenile Jian carp. PMID:24751923
[Textual Research on Wang Fengchun's Life].
Wang, Ti
WANG Fengchun (1884 - 1949), born in Wu County, Jiangsu Province, was one of the four famous doctors of Beijing in the Republic of China periods. He learned Confucianism during his childhood and then learned medicine from AI Buchan, a famous doctor in Wuzhong area. In 1908, he went to Beijing and was appointed as the prosecutor of the court of law and a medical official, but also had learnt medicine from LI Jun, the head of the Business Ministry. In 1910, Wang resigned and lived as doctor in Beijing. According to the literature, from 1935 to 1942, Wang had been appointed 11 times as a member of Beiping (Beijing) TCM examination committee or test committee. In 1938, he was appointed as president of the Beijing Branch of the National Medical Professional Association and created the Beijing Medicine Monthly in 1939. In September 1939, Wang began to make preparations for a TCM symposium, i.e. the Medicine Symposium which was established officially in October 1939. In 1941, he was appointed as the director of the Beijing Traditional Chinese Medicines Workshop, employing famous doctors to cultivate reserve talents of medicines. Being a realist, he often exchanged opinions with TCM and western medical doctors and also made a contribution to medical education. PMID:22613482
County town -- jian-zhi town differentials and migration to towns in China.
Ma, R
China's urbanization process is unique in having been due to economic systems and migration policies. Towns and townships in rural areas are different from cities in their social and economic characteristics and their structure and function. The urban system in China is initially described with the distinction drawn between cities, "jian-zhi towns", (organic town) which are officially recognized, and rural areas. Analysis is provided f the economic and residential registration status of town residents and migration in northern China. Data were obtained from a 1987 survey of 1314 households in Wongnioute Banner in Inner Mongolia, and a 1985 migration survey of 2089 rural households in 41 villages. The study area was selected because jian-zhi town status was easily obtained and the are needed more towns for local administration and trade; the area was similar in geographic, social, economic, and cultural characteristics to other northern and northwestern regions. The Wongnioute Banner comprises 5 towns (Qiaotou, Wufendi, Hairesu, Wuduentaohai, and Wutonghua) and 1 country town (Wudan). All citizens from birth have an agricultural or nonagricultural status, which can be changed by passing national exams or completing a university education, joining the military and becoming an officer, marrying someone with a nonagricultural status, reunifying the family, or holding a special program. Quotas are set annually for status changes, e.g. in Tibet Autonomous Region the annual quota was 3%. Town residents may have either status. In the sample, 56.6% lived in town and had a nonagricultural status; 17.7% of heads of household town residents had an agricultural status and had stronger ties to villages because of family connections. Commuters are a third group and comprise 8.9%. County towns and jian-zhi towns are grouped the same, but are quite different in population size. Wudan had a population of 27,600 spread over an area of 480 hectares. The jian-zhi towns each had an
[Probing the cause on Wang Qingrens idea of "Fallacious theory, effective prescription" of Wang Qingren].
Pan, Da-wei
The theory of human body in Yilin Gaicuo (Correction on Errors in Medical Classics) by Wang Qingren in late Qing Dynasty is different from that of traditional Chinese Medicine and that of anatomy of western medicine. However, the prescriptions recorded in Yilin Gaicuo (Correction on Errors in Medical Classics) are indeed effective clinically. The paradox of "Fallacious theory, effective prescription" suggests that the theories of Wang Qingren are not superficial in anatomy. By carefully analyzing the concept of zang-fu organs and concept of qi and blood as well as the theory of human body in Yilin Gaicuo (Correction on Errors in Medical Classics), although many viewpoints of theories of Wang Qingren deviates from that of traditional Chinese Medicine, they inherits the qi and blood concept, the core theory of Chinese Medicine. Therefore, the theories belong to the theoretical scope of Chinese Medicine. The root of "Fallacious theory, effective prescription" is in the heritage of the qi and blood concept. The set view of Wang Qingren in criticizing the theories of traditional Chinese Medicine and establishing new theories revealed in this process possesses the significance of revelation to the contemporary Chinese Medicine.

[Analysis of Wang Shuhe's academic contribution and epistemology].
Meng, Qin-Yun
Wang Shuhe is considered to be Zhang Zhongjing's disciple according to four reasons: A. the acquaintance of Yu Jiaxi and Fan Xingzhun and others. B. the close relation of Wang Shuhe and Wei Xun. C. Zhang Zhongjing's complete works kept by Wang Shuhe and Wang Shuhe's autobiography. D. the record in Maijing and that Wang Shuhe called Zhang Zhongjing master. It was speculated that Wang Shuhe was the minister of imperial medical affairs of the Wu Kingdom from the title of the emperor's reign recorded by Huang Fumi and Jingzhou's attribution. He contributed to Traditional Chinese Medicine in three aspects-preserving and classifying Zhang Zhongjng's complete works; preserving literature on pulse diagnosis, writing Maijing and standardizing methods for pulse-taking; and advancing the concept of syndrome and Bianzheng (transmutation with steaming in infant feverish perspiration), probing the theory of feverish diseases, and people's well-being, demonstrating the spirit of Bianzhenglunzhi.

Weighted Lin-Wang tests for crossing hazards.
Koziol, James A; Jia, Zhenyu
Lin and Wang have introduced a quadratic version of the logrank test, appropriate for situations in which the underlying survival distributions may cross. In this note, we generalize the Lin-Wang procedure to incorporate weights and investigate the performance of Lin and Wang's test and weighted versions in various scenarios. We find that weighting does increase statistical power in certain situations; however, none of the procedures was dominant under every scenario. PMID:24795776

Jian carp (Cyprinus carpio var. Jian) intestinal immune responses, antioxidant status and tight junction protein mRNA expression are modulated via Nrf2 and PKC in response to dietary arginine deficiency.
Wang, Biao; Feng, Lin; Chen, Gang-Fu; Jiang, Wei-Dan; Liu, Yang; Kuang, Sheng-Yao; Jiang, Jun; Tang, Ling; Wu, Pei; Tang, Wu-Neng; Zhang, Yong-An; Zhao, Juan; Zhou, Xiao-Qiu
This study investigated the effect of dietary arginine on the immune response, antioxidant status and tight junction mRNA expression in the intestine of juvenile Jian carp (Cyprinus carpio var. Jian). A total of 1200 juvenile Jian carp with an average initial weight of 6.33 ± 0.03 g were fed graded levels of arginine (9.8-24.5 g kg(-1) diet) for nine weeks. The study showed that arginine deficiency up-regulated interleukin 1, interleukin 8 and transforming growth factor-β and down-regulated tumour necrosis factor α gene expression (P < 0.05). Additionally, arginine deficiency increased malondialdehyde (MDA), protein carbonyl (PC) and glutathione contents and decreased the activities of copper/zinc superoxide dismutase (SOD1), glutathione peroxidase (GPx), catalase (CAT) and glutathione reductase (GR) and glutathione-S-transferase (GST) (P < 0.05). Meanwhile, arginine deficiency significantly increased claudin 7, occludin, protein kinase C, NF-E2-related factor 2 and Kelch-like-ECH- associated protein 1 mRNA expression and decreased SOD1, CAT and GR mRNA expression (P < 0.05). All of these results indicated that arginine deficiency impaired intestinal immune function via the regulation of mRNA expression of cytokines, tight junction proteins, antioxidant enzymes, Nrf2/Keap1 and PKC in fish intestine.

[Study of dates of birth and death of WANG Tao].
Song, Zhen-Min
The dates of birth and death of WANG Tao, a famous doctor in Tang dynasty, are not found in literature and scholars have different points upon this subject. It could be sure that WANG Tao was appointed mayor of Huayuan county in the ninth year of Kaiyuan period (721) and in December of the fourteenth year of Tianbao period (756) he the revolt in Hejian. The recording after 756 could not be found in literature. According to the official system in Tang dynasty that officers retired at their age of 70, it could be sure that WANG Tao was less than 70 year old in 756. Considering his age when he was the county mayor in 721, it could be speculated that WANG Tao was born during the third year of Chuigong period (687) to the second year of Changshou period (693), and his death date should be some date after 756. But it couldn't be validated. PMID:21624275
Chemical gas-dynamics beyond Wang Chang-Uhlenbeck's kinetics
Kolesnichenko, Evgeniy G.; Gorbachev, Yuriy E.
Wang Chang-Uhlenbeck equation does not give possibility to take into account intermolecular processes such as redistribution of the energy among different degrees of freedom. The modification of the generalized Wang Chang-Uhlenbeck equation including such processes is proposed. It allows to study for instance the kinetics of non-radiative transitions. Limitations of this approach are connected with the requirements of absence of polarization of rotational momentum and phases of intermolecular vibrations.
Massively parallel Wang Landau sampling on multiple GPUs
Yin, Junqi; Landau, D. P.
Wang Landau sampling is implemented on the Graphics Processing Unit (GPU) with the Compute Unified Device Architecture (CUDA). Performances on three different GPU cards, including the new generation Fermi architecture card, are compared with that on a Central Processing Unit (CPU). The parameters for massively parallel Wang Landau sampling are tuned in order to achieve fast convergence. For simulations of the water cluster systems, we obtain an average of over 50 times speedup for a given workload.
Effects of Ala-Gln feeding strategies on growth, metabolism, and crowding stress resistance of juvenile Cyprinus carpio var. Jian.
Chen, Xiu-Mei; Guo, Gui-Liang; Sun, Li; Yang, Qiu-Shi; Wang, Gui-Qin; Qin, Gui-Xin; Zhang, Dong-Ming
The present study was conducted to evaluate the effects of different L-alanyl-l-glutamine (Ala-Gln) feeding strategies on the growth performance, metabolism and crowding stress resistance related parameters in juvenile Jian carp (Cyprinus carpio var. Jian) under crowded condition (80 g/L). Juvenile Jian carp (initial weight 26.1 ± 0.6 g) were distributed into five groups which fed with graded concentrations (0% or 1.0%) of Ala-Gln for eight weeks. Control group (I, 0/0) fed with control diet (0% Ala-Gln) throughout the feeding trial. The other four groups employed different control and experimental diet feeding strategies ranging from two weeks control diet fed and two weeks experimental diet (1% Ala-Gln) fed (II, 0/2) to eight weeks experimental diet fed (V, 4/4). Results revealed that Mean weight gain (MEG) under all different feeding strategies of Ala-Gln were significantly higher than that of the control group (p < 0.05), and MEG of group II (201.90%) was even higher than that of group IV (184.70%). Liver glycogen and blood total protein of groups II, III and V were significantly higher than that in groups I and IV (p < 0.05). The highest level of serum thyroxine (10.07 ng/ml), insulin-like growth factor-I (52.40 ng/ml) and insulin (9.73 μ IU/mL) were observed in group V. However, diet supplemented with Ala-Gln did not affect the levels of serum glucose, cortisol and catecholamine in fish. The mRNA expression of GR1a, GR1b and GR2 were also significantly changed in Ala-Gln supplementation groups compared with control group (p < 0.05). After fish intraperitoneally injected with virulent Aeromonas hydrophila, the fish survival rates were significantly increased in all Ala-Gln supplementation groups compared with control group (p < 0.05). Results from the present experiment showed the importance of dietary supplementation of Ala-Gln in benefaction of the growth performance, metabolism and crowding stress resistance in Jian carp breeding.

Spatial chaos of Wang tiles with two symbols
NASA Astrophysics Data System (ADS)
Chen, Jin-Yu; Chen, Yu-Jie; Hu, Wen-Guei; Lin, Song-Sun
This investigation completely classifies the spatial chaos problem in plane edge coloring (Wang tiles) with two symbols. For a set of Wang tiles B , spatial chaos occurs when the spatial entropy h ( B ) is positive. B is called a minimal cycle generator if P ( B ) ≠ 0̸ and P ( B ' ) = 0̸ whenever B ' ⫋ B , where P ( B ) is the set of all periodic patterns on ℤ2 generated by B . Given a set of Wang tiles B , write B = C 1 ∪ C 2 ∪ ⋯ ∪ C k ∪ N , where Cj, 1 ≤ j ≤ k, are minimal cycle generators and B contains no minimal cycle generator except those contained in C1∪C2∪⋯∪Ck. Then, the positivity of spatial entropy h ( B ) is completely determined by C1∪C2∪⋯∪Ck. Furthermore, there are 39 equivalence classes of marginal positive-entropy sets of Wang tiles and 18 equivalence classes of saturated zero-entropy sets of Wang tiles.

This study was designed to investigate the effects of dietary glutamine on the growth performance, cytokines, target of rapamycin (TOR), and antioxidant-related parameters in the spleen and head kidney of juvenile Jian carp (Cyprinus carpio var. Jian). Fish were fed the basal (control) and glutamine-supplemented (12.0 g glutamine kg(-1) diet) diets for 6 weeks. Results indicated that the dietary glutamine supplementation improved the growth performance, spleen protein content, serum complement 3 content, and lysozyme activity in fish. In the spleen, glutamine down-regulated the expression of the interleukin 1 and interleukin 10 genes, and increased the level of phosphorylation of TOR protein. In the head kidney, glutamine down-regulated the tumor necrosis factor α and interleukin 10 gene expressions, phosphorylated and total TOR protein levels, while up-regulated the transforming growth factor β2 gene expression. Furthermore, the protein carbonyl content was decreased in the spleen of fish fed glutamine-supplemented diet; conversely, the anti-hydroxyl radical capacity and glutathione content in the spleen were increased by glutamine. However, diet supplemented with glutamine did not affect the lipid peroxidation, anti-superoxide anion capacity, and antioxidant enzyme activities in the spleen. Moreover, all of these antioxidant parameters in the head kidney were not affected by glutamine. Results from the present experiment showed the importance of dietary supplementation of glutamine in benefaction of the growth performance and several components of the innate immune system, and the deferential role in cytokine gene expression, TOR kinase activity, and antioxidant status between the spleen and head kidney of juvenile Jian carp.

Learning from the past: Rare ε-Fe2O3 in the ancient black-glazed Jian (Tenmoku) wares
Dejoie, Catherine; Sciau, Philippe; Li, Weidong; Noé, Laure; Mehta, Apurva; Chen, Kai; Luo, Hongjie; Kunz, Martin; Tamura, Nobumichi; Liu, Zhi
Ancient Jian wares are famous for their lustrous black glaze that exhibits unique colored patterns. Some striking examples include the brownish colored "Hare's Fur" (HF) strips and the silvery "Oil Spot" (OS) patterns. Herein, we investigated the glaze surface of HF and OS samples using a variety of characterization methods. Contrary to the commonly accepted theory, we identified the presence of ε-Fe2O3, a rare metastable polymorph of Fe2O3 with unique magnetic properties, in both HF and OS samples. We found that surface crystals of OS samples are up to several micrometers in size and exclusively made of ε-Fe2O3. Interestingly, these ε-Fe2O3 crystals on the OS sample surface are organized in a periodic two dimensional fashion. These results shed new lights on the actual mechanisms and kinetics of polymorphous transitions of Fe2O3. Deciphering technologies behind the fabrication of ancient Jian wares can thus potentially help researchers improve the ε-Fe2O3 synthesis. PMID:24820819

[The features of studies on cold pathogenic diseases in Yi zong jin jian (Golden mirror of orthodox medicine)].
Huang, Hai
As a voluminous work compiled and published by the Qing palace, Yi zong jin jian (Golden Mirror of Orthodox medicine) contains a "Revised Complete Book of Zhongjing" as its first volume which is very unique, systematic, and comprehensive. It re-categorizes the entries of the original Shang han lun (Treatiseon cold Tathogenic Diseases) based on its sections and chapters. and reasonably incorporates entries with similar contents. It also reasonably annotates those complex entries, boldly revises the wrong and missing entries, and applies the theories of "tripartite 3 outlines" as the basis for compiling the chapters and sections of Taiyang diseases, and as the tools for explaining the entries. Among them, some are compiled in verses for easy memory. PMID:12921589
Minister Wang Wei on family planning policy and population aging.
Mr. Wang Wei, Minister-in-Charge of the State Family Planning Commission, was interviewed by the correspondent of the magazine "Outlook Weekly" on the 16th of last July in Beijing. Mr. Wang Wei said that the aging process of China's population could not be separated from the family planning program which was an important factor leading to China's population aging. He also said that population aging in China would have its limit as any development does. The aging of China's population is the manifestation of the contradiction between the unplanned and planned reproduction of its population. Population aging will disappear as soon as the contradiction is settled. Since the aging of China's population is caused by the decrease of children, one cannot only see the social burden aggravated by the relative increase in elderly population but should also see the social burden alleviated by the decrease in the absolute number of children. Only by doing so can one see the whole picture. The allegation made by some people that the social dependency ratio would increase due to population aging is groundless. Mr. Wang Wei does not agree with the viewpoint that China may relax its policy of family planning to some extent on the ground that population aging causes the decrease in the total social dependency ratio so as to ease the difficulties brought about by the rapid population aging. The basic state policy of striving to quadruple the gross output value of industry and agriculture and to control China's population at about 1.2 billion at the end of the century is the correct policy to solve the problem of population aging in China, and it is also the only alternative.

The effect of Chinese herbal medicine Jian Ling Decoction for the treatment of essential hypertension: a systematic review
Xiong, Xingjiang; Wang, Pengqian; Li, Xiaoke; Zhang, Yuqing
Objectives Jian Ling Decoction (JLD) is often prescribed to improve hypertension-related symptoms in China. However, this treatment has not been systematically reviewed for its efficacy against essential hypertension (EH). This review aims to assess the current clinical evidence of JLD in the treatment of EH. Design Seven electronic databases, including the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, the Chinese National Knowledge Infrastructure (CNKI), the Chinese Scientific Journal Database (VIP), the Chinese Biomedical Literature Database (CBM) and the Wanfang Database, were searched up to March 2014. Randomised control trials (RCTs) comparing JLD or combined with antihypertensive drugs versus antihypertensive drugs were included. We assessed the methodological quality, extracted the valid data and conducted the meta-analysis according to criteria from the Cochrane group. The primary outcome was categorical or continuous blood pressure (BP), and the secondary outcome was quality of life (QOL). Results Ten trials (655 patients) with unclear-to-high risk of bias were identified. Meta-analysis showed that JLD used alone showed no BP reduction effect; however, improvement on QOL was found in the JLD group compared to antihypertensive drugs. A significant reduction in systolic and diastolic BP was observed for JLD plus antihypertensive drugs when compared with antihypertensive drugs alone. No serious adverse effects were reported. Conclusions Owing to insufficient clinical data, it is difficult to draw a definite conclusion regarding the effectiveness and safety of JLD for EH, and better trials are needed. PMID:25652798
Ke Wang, a Chinese television soap opera with a message.
Wang, M; Singhal, A
The Chinese soap opera, Ke Wang, was created by Li Xiaoming between August 1989 and June 1990 and produced at a cost of US$4650 per episode. The characters were drawn from everyday ordinary Chinese life: a traditional and open-minded and caring woman, a typical mother who works hard and loves her children, a highly educated upwardly mobile man who divorces his wife, a professor criticized during the Cultural Revolution, a doctor prejudiced against ordinary people, a kind honest man who marries the divorcee, a friend of the divorcee, a man who is optimistic in spite of bad experiences during the Cultural Revolution, and an excellent medical doctor who also resolves conflicts. The program was very popular, even among Communists, because of its value-based content, the real-life nature of the show, the change from highly restricted programming, the elaborate and supportive media coverage, and dialogue which closely matches audience preferences. The show has been aired by over 100 stations to date and has reached a total estimated audience of 550 million. The sale of television sets has increased since the show's appearance. The script reflects the conflicts between traditional and modern Chinese values. Pro-social values and behaviors are learned from the role models depicted; examples are given of immediate social impact. Ke Wang was a by-product of the Beijing Television Arts Center's interest in designing television programs that are relevant to the lives of ordinary people. The 60-minute scripts dealt with issues such as the status of women, social morality, family harmony, class conflict, responsible parenthood, maintenance of traditional culture, volunteerism, child development, and coping with physical disability. The Chinese government hailed Ke Wang as model television and awarded US$20,000 in prize money to the producers. The Chinese government is planning to produce other entertainment-education soap operas, which raises the problem of blatant, political
Multiple Walkers in the Wang-Landau Algorithm
Brown, G
The mean cost for converging an estimated density of states using the Wang-Landau algorithm is measured for the Ising and Heisenberg models. The cost increases in a power-law fashion with the number of spins, with an exponent near 3 for one-dimensional models, and closer to 2.4 for two-dimensional models. The effect of multiple, simultaneous walkers on the cost is also measured. For the one-dimensional Ising model the cost can increase with the number of walkers for large systems. For both the Ising and Heisenberg models in two-dimensions, no adverse impact on the cost is observed. Thus multiple walkers is a strategy that should scale well in a parallel computing environment for many models of magnetic materials.
Wang-Landau simulation of Gō model molecules.
Böker, Arne; Paul, Wolfgang
Gō-like models are one of the oldest protein modeling concepts in computational physics and have proven their value over and over for forty years. The essence of a Gō model is to define a native contact matrix for a well-defined low-energy polymer configuration, e.g., the native state in the case of proteins or peptides. Many different potential shapes and many different cut-off distances in the definition of this native contact matrix have been proposed and applied. We investigate here the physical consequences of the choice for this cut-off distance in the Gō models derived for a square-well tangent sphere homopolymer chain. For this purpose we are performing flat-histogram Monte Carlo simulations of Wang-Landau type, obtaining the thermodynamic and structural properties of such models over the complete temperature range. Differences and similarities with Gō models for proteins and peptides are discussed. PMID:26810395
Improving Wang-Landau sampling with adaptive windows
NASA Astrophysics Data System (ADS)
Cunha-Netto, A. G.; Caparica, A. A.; Tsai, Shan-Ho; Dickman, Ronald; Landau, D. P.
Wang-Landau sampling (WLS) of large systems requires dividing the energy range into "windows" and joining the results of simulations in each window. The resulting density of states (and associated thermodynamic functions) is shown to suffer from boundary effects in simulations of lattice polymers and the five-state Potts model. Here, we implement WLS using adaptive windows. Instead of defining fixed energy windows (or windows in the energy-magnetization plane for the Potts model), the boundary positions depend on the set of energy values on which the histogram is flat at a given stage of the simulation. Shifting the windows each time the modification factor f is reduced, we eliminate border effects that arise in simulations using fixed windows. Adaptive windows extend significantly the range of system sizes that may be studied reliably using WLS.
[Mr. Wang Le-ting: a master of acupuncture].
Niu, Xue-Song; Wang, Fan
Mr. WANG Le-ting attaches great importance to accurate differentiation of syndromes, strict selection of acupoints, technique and direction of needle insertion, clear reinforcing and reducing methods after the appearance of needling sensations, proper opportunities of manipulations as well as needle withdrawal techniques, and reasonable application of acupuncture and moxibustion respectively. The above mentioned principles are known as his "5 agreements". He emphasizes that the selection of acupoints should be "in accordance with both the meridians and the accurate location of the points", and "needling sensation is necessary for each point". He holds that the back-shu points of the five-zang organs and Geshu (BL 17) can be adopted for patient with deficiency of qi, blood, yin and yang. In the aspect of acupoint theory, he insists the accurate location of Xuanzhong (GB 39). He also adjusts the locations of Huatuo Jiaji (EX-B 2) points, and finds the location of the new Dubi (ST 35). For easier applications, he divides the functions of acupoints into different schools of qi, blood, cold, heat, deficiency, excess, wind and dampness. And 41 combinations of acupoints are also invented as innovation. He is always strict to his students, instructing and influencing them by his own words and deeds. He is always conscientious and meticulous, which benefit immensely his followers, and remains a lot of precious experiences for the later generations. PMID:23214000

Linshaw, Andrew R.
The Lie algebra D of regular differential operators on the circle has a universal central extension {hat{D}} . The invariant subalgebra {hat{D}^+} under an involution preserving the principal gradation was introduced by Kac, Wang, and Yan. The vacuum {hat{D}^+} -module with central charge {c in C} , and its irreducible quotient {V}_c, possess vertex algebra structures, and {V}_c has a nontrivial structure if and only if c in 1/2 Z. We show that for each integer {n > 0} , V_{n/2} and V_{-n} are W -algebras of types W(2, 4,dots,2n) and W(2, 4,dots, 2n^2 + 4n), respectively. These results are formal consequences of Weyl's first and second fundamental theorems of invariant theory for the orthogonal group {O(n)} and the symplectic group {Sp(2n)} , respectively. Based on Sergeev's theorems on the invariant theory of {Osp(1, 2n)} we conjecture that V_{-n+1/2} is of type W(2, 4,dots, 4n^2 + 8n + 2), and we prove this for {n = 1} . As an application, we show that invariant subalgebras of {βγ} -systems and free fermion algebras under arbitrary reductive group actions are strongly finitely generated.

Generalizing Swendsen-Wang to sampling arbitrary posterior probabilities.
Barbu, Adrian; Zhu, Song-Chun
Many vision tasks can be formulated as graph partition problems that minimize energy functions. For such problems, the Gibbs sampler provides a general solution but is very slow, while other methods, such as Ncut and graph cuts are computationally effective but only work for specific energy forms and are not generally applicable. In this paper, we present a new inference algorithm that generalizes the Swendsen-Wang method to arbitrary probabilities defined on graph partitions. We begin by computing graph edge weights, based on local image features. Then, the algorithm iterates two steps. 1) Graph clustering: It forms connected components by cutting the edges probabilistically based on their weights. 2) Graph relabeling: It selects one connected component and flips probabilistically, the coloring of all vertices in the component simultaneously. Thus, it realizes the split, merge, and regrouping of a "chunk" of the graph, in contrast to Gibbs sampler that flips a single vertex. We prove that this algorithm simulates ergodic and reversible Markov chain jumps in the space of graph partitions and is applicable to arbitrary posterior probabilities or energy functions defined on graphs. We demonstrate the algorithm on two typical problems in computer vision--image segmentation and stereo vision. Experimentally, we show that it is 100-400 times faster in CPU time than the classical Gibbs sampler and 20-40 times faster then the DDMCMC segmentation algorithm. For stereo, we compare performance with graph cuts and belief propagation. We also show that our algorithm can automatically infer generative models and obtain satisfactory results (better than the graphic cuts or belief propagation) in the same amount of time.

A new paradigm for petascale Monte Carlo simulation: Replica exchange Wang Landau sampling
Li, Ying Wai; Vogel, Thomas; Wuest, Thomas; Landau, David P
We introduce a generic, parallel Wang Landau method that is naturally suited to implementation on massively parallel, petaflop supercomputers. The approach introduces a replica-exchange framework in which densities of states for overlapping sub-windows in energy space are determined iteratively by traditional Wang Landau sampling. The advantages and general applicability of the method are demonstrated for several distinct systems that possess discrete or continuous degrees of freedom, including those with complex free energy landscapes and topological constraints.
[Effect of preventive and therapeutical function of jian-pi yi-qi li-shui decoction on cisplatin nephrotoxicity in rats].
Cheng, J H
The effect of preventive and therapeutical function of Chinese herbs compound prescription Jian-Pi Yi-qi Li-Shui decoction (JPYQLSD) on cisplatin (DDP) and nephrotoxicity of rat. It was carried out that the prescription JPYQLSD had notable result in reducing content of serum urea nitrogen, glucosaminidase, beta 2-microglobulin of the rats (P < 0.05). JPYQLSD also could alleviate inhibition on activity of adenosine triphosphatase (ATP-ase). Pathological examination revealed the protective effect of the JPYQLSD on kidneys of rats. It suggested that JPYQLSD has a good effect on preventive and therapeutical function of Cisplatin (DDP) nephrotoxicity. The mechanism of JPYQLSD was to regulate the energy metabolism of rats.

Replica-exchange Wang Landau sampling: pushing the limits of Monte Carlo simulations in materials sciences
Perera, Meewanage Dilina N; Li, Ying Wai; Eisenbach, Markus; Vogel, Thomas; Landau, David P
We describe the study of thermodynamics of materials using replica-exchange Wang Landau (REWL) sampling, a generic framework for massively parallel implementations of the Wang Landau Monte Carlo method. To evaluate the performance and scalability of the method, we investigate the magnetic phase transition in body-centered cubic (bcc) iron using the classical Heisenberg model parameterized with first principles calculations. We demonstrate that our framework leads to a significant speedup without compromising the accuracy and precision and facilitates the study of much larger systems than is possible with its serial counterpart.

Soil Organic Carbon Pool and Its Chemical Composition in Phyllostachy pubescens Forests at Two Altitudes in Jian-ou City, China
Ji, Haibao; Zhuang, Shunyao; Zhu, Zhaoliang; Zhong, Zheke
Phyllostachys pubescens forests play an important role in soil organic carbon (SOC) sequestration in terrestrial ecosystems. However, the estimation and mechanism of SOC sequestration by P. pubescens forests remain unclear. In this study, the effect of P. pubescens forest distribution with elevation was investigated at two altitude sites in Jian-ou City, Southeast China. SOC storage was estimated and its chemical composition was obtained via 13C-nuclear magnetic resonance (NMR), chemical classification, and spectral analysis. Results showed that the SOC contents and stocks were significantly higher at the high-altitude site than at the low-altitude site in the entire soil profile (0–60 cm). The C contents of the three combined humus forms exhibited similar responses to the elevation change, and all of these forms were higher at the high-altitude site than at the low-altitude site regardless of soil layer. However, the proportions of the three combined humus C showed no significant differences between the two altitudes. The results of 13C-NMR showed that the SOC chemical composition did not significantly vary with elevation as well. This finding was consistent with the E465/E665 of the loosely combined humus. Overall, the results suggested that altitude should be considered during regional SOC estimation and that altitude affected the quantity rather than the quality of the SOC under the same P. pubescens vegetation.

Chinese Medicine Formula "Jian-Pi-Zhi-Dong Decoction" Attenuates Tourette Syndrome via Downregulating the Expression of Dopamine Transporter in Mice
Wang, Dao-han; Li, Wei; Liu, Xiao-fang; Zhang, Jin-ming; Wang, Su-mei
Jian-Pi-Zhi-Dong Decoction (JPZDD) is dedicated to the treatment for Tourette syndrome (TS) with the guidance of the theories of Traditional Chinese Medicine (TCM). This study aims to investigate the expression of dopamine transporter (DAT) in the striatum and stereotyped behavior of TS mice model by intervention of JPZDD. Mice were induced by 3,3′-iminodipropionitrile (IDPN, 350 mg kg−1 day−1, i.p.) for 7 days and divided into 4 groups (n = 20, each): control and IDPN groups were gavaged with saline and the remaining 2 groups with Tiapride (Tia, 50 mg kg−1 day−1) and JPZDD (20 g kg−1 day−1), respectively. The results showed that the scores of stereotyped behavior in IDPN+JPZDD group were significantly reduced. A noticeably increased 11C-β-CFT binding at bilateral striatum was observed after administration of JPZDD versus that of IDPN or Tia. Immunohistochemistry and in situ hybridization studies manifested higher levels of DAT protein and mRNA in IDPN+JPZDD group. These findings not only demonstrated that JPZDD could effectively inhibit the abnormal behaviors of TS mice model, but also increase the level of DAT in striatum. Therefore, JPZDD could be one of potential treatments of patients with TS. PMID:23431337
[Clinical study on prevention and treatment to chemotherapy caused nephrotoxicity with jian-pi yi-qi li-shui Decoction].
Cheng, J H
95 cases of cancer patients were treated with large dose of Cisplatinum. They were randomly divided into treated group with Chinese medicinal herbs (49 cases) and control group with hydration treatment (46 cases). Multiple indexes were selected to observe effect on renal function. The result showed that the level of blood urea nitrogen (BUN), creatnine (Cr), beta 2 microglobulin (beta 2-MG), urea N-acetyl-beta-glucosaminidase (NAG) of treated group lowered. After treatment the difference of BUN, Cr between the two groups was significant (P < 0.05). It suggested that Jian-Pi Yi-Qi Li-Shui Decoction (JPYQLSD) was superior to hydration group in preventing the large dose of Cisplatinum induced nephrotoxicity. It was also used to treat 44 cases-times of chemotherapy caused renal failure. The total effect rate is 93.18%. The difference of the level of BUN, Cr between before and after treatment was very significant (P < 0.01). It is proved that JPYQLSD has good effect in treating chemotherapy caused renal failure.

Wang OIS glossary package for reformatting documents telecommunicated to the OIS system
Markow, S.R.
Documents that are composed on a computer and then transmitted by telecommunications into a Wang Office Information System (OIS) word processing system need to be reformatted and cleaned up before they can be used properly as word processing documents suitable for further revisions or additions. This report describes a group of glossary entries created for the Wang OIS which simplifies the job of cleaning up telecommunicated documents. This glossary is a semi-automated process designed to eliminate most of the tedious work needed to be performed in removing extra spaces and returns, adjusting formats, moving material, repagination, using tabs or indents, and similar problems. The report briefly discusses the problems, describes the glossary approach to solving them, and gives instructions for actually using the glossary entries.

In Kanerva's Sparse Distributed Memory, writing to and reading from the memory are done in relation to spheres in an n-dimensional binary vector space. Thus it is important to know how many points are in the intersection of two spheres in this space. Two proofs are given of Wang's formula for spheres of unequal radii, and an integral approximation for the intersection in this case.
Wang-Landau sampling in face-centered-cubic hydrophobic-hydrophilic lattice model proteins
NASA Astrophysics Data System (ADS)
Liu, Jingfa; Song, Beibei; Yao, Yonglei; Xue, Yu; Liu, Wenjie; Liu, Zhaoxia
Finding the global minimum-energy structure is one of the main problems of protein structure prediction. The face-centered-cubic (fcc) hydrophobic-hydrophilic (HP) lattice model can reach high approximation ratios of real protein structures, so the fcc lattice model is a good choice to predict the protein structures. The lacking of an effective global optimization method is the key obstacle in solving this problem. The Wang-Landau sampling method is especially useful for complex systems with a rough energy landscape and has been successfully applied to solving many optimization problems. We apply the improved Wang-Landau (IWL) sampling method, which incorporates the generation of an initial conformation based on the greedy strategy and the neighborhood strategy based on pull moves into the Wang-Landau sampling method to predict the protein structures on the fcc HP lattice model. Unlike conventional Monte Carlo simulations that generate a probability distribution at a given temperature, the Wang-Landau sampling method can estimate the density of states accurately via a random walk, which produces a flat histogram in energy space. We test 12 general benchmark instances on both two-dimensional and three-dimensional (3D) fcc HP lattice models. The lowest energies by the IWL sampling method are as good as or better than those of other methods in the literature for all instances. We then test five sets of larger-scale instances, denoted by the S, R, F90, F180, and CASP target instances on the 3D fcc HP lattice model. The numerical results show that our algorithm performs better than the other five methods in the literature on both the lowest energies and the average lowest energies in all runs. The IWL sampling method turns out to be a powerful tool to study the structure prediction of the fcc HP lattice model proteins.
Exploring new frontiers in statistical physics with a new, parallel Wang-Landau framework
Vogel, Thomas; Li, Ying Wai; Wuest, Thomas; Landau, David P
Combining traditional Wang Landau sampling for multiple replica systems with an exchange of densities of states between replicas we describe a general framework for simulations on massively parallel Petaflop supercomputers. The advantages and general applicability of the method for simulations of complex systems are demonstrated for the classical 2D Potts spin model featuring a strong first-order transition and the self-assembly of lipid bilayers in amphiphilic solutions in a continuous model.

This hybrid scheme combines the advantages of Wang-Landau and Replica-Exchange algorithms, and the one-dimensional version of this approach has been shown to be very efficient and to scale well, up to several thousands of computing cores. This approach allows us to split the parameter space of the system to be simulated into several pieces and still perform a random walk over the entire parameter range, ensuring the ergodicity of the simulation. Previous work, in which a similar scheme of parallel simulation was implemented without using replica exchange and with a different way to combine the result from the pieces, led to discontinuities in the final density of states over the entire range of parameters. From our simulations, it appears that the replica-exchange Wang-Landau algorithm is able to overcome this diculty, allowing exploration of higher parameter phase space by keeping track of the joint density of states.
Urine metabolic profile changes of CCl4-liver fibrosis in rats and intervention effects of Yi Guan Jian Decoction using metabonomic approach
Background Yi Guan Jian Decoction (YGJD), a famous Chinese prescription, has long been employed clinically to treat liver fibrosis. However, as of date, there is no report on the effects of YGJD from a metabonomic approach. In this study, a urine metabonomic method based on gas chromatography coupled with mass spectrometry (GC/MS) was employed to study the protective efficacy and metabolic profile changes caused by YGJD in carbon tetrachloride (CCl4)-induced liver fibrosis. Methods Urine samples from Wistar rats of three randomly divided groups (control, model, and YGJD treated) were collected at various time-points, and the metabolic profile changes were analyzed by GC/MS with principal component analysis (PCA) and partial least squares-discriminate analysis (PLS-DA). Furthermore, histopathology and biochemical examination were also carried out to ensure the success of CCl4-induced liver fibrosis model. Results Urine metabolic profile studies suggested distinct clustering of the three groups, and YGJD group was much closer to the control group by showing a tendency of recovering towards the control group. Fourteen significantly changed metabolites were found, and YGJD treatment could reverse the levels of these metabolites to normal levels or close to normal levels. Conclusions The current study indicates that the YGJD has significant anti-fibrotic effects on CCl4-induced liver fibrosis in rats, which might be by regulating the dysfunction of energy metabolism, amino acid metabolism, tryptophan metabolism, cytochrome P450 metabolism, and gut microflora metabolism. The metabonomic approach can be recommended to study the pharmacological effect and mechanism of complex Chinese medicines. PMID:23725349
Protein folding of the H0P model: A parallel Wang-Landau study
Shi, Guangjie; Wuest, Thomas; Li, Ying Wai; Landau, David P
We propose a simple modication to the hydrophobic-polar (HP) protein model, by introducing a new type of monomer, "0", with intermediate hydrophobicity of some amino acids between H and P. With the replica-exchange Wang-Landau sampling method, we investigate some widely studied HP sequences as well as their H0P counterparts and observe that the H0P sequences exhibit dramatically reduced ground state degeneracy and more signicant transition signals at low temperature for some thermodynamic properties, such as the specific heat.
[Analysis on professor WANG Juyi's crevice theory from Tao Teh King].
Luo, Lu; Wang, Juyi
The crevice theory proposed by professor WANG Juyi is analyzed in this article. In the crevice theory, it is believed that the meridians are located among "skin, pulse, flesh, tendon and bone", and the crevice is the path for the transportation of qi-blood and body fluid in the body, which is the essential condition for vital movement. This is in agreement with the idea of "action through inaction" from Tao Teh King. Based on crevice theory, the abnormalities of meridians can reflex the deficiency and excess of diseases, and regulating meridians is a significant way to treat diseases, and maintaining smooth meridian is important for healthcare.

Security analysis of boolean algebra based on Zhang-Wang digital signature scheme
Zheng, Jinbin
In 2005, Zhang and Wang proposed an improvement signature scheme without using one-way hash function and message redundancy. In this paper, we show that this scheme exits potential safety concerns through the analysis of boolean algebra, such as bitwise exclusive-or, and point out that mapping is not one to one between assembly instructions and machine code actually by means of the analysis of the result of the assembly program segment, and which possibly causes safety problems unknown to the software.
Wang-Landau Algorithm for Continuous Models and Joint Density of States
Zhou, Chenggang; Schulthess, Thomas C; Torbrugge, S.; Landau, D. P.
We present a modified Wang-Landau algorithm for models with continuous degrees of freedom. We demonstrate this algorithm with the calculation of the joint density of states of ferromagnet Heisenberg models and a model polymer chain. The joint density of states contains more information than the density of states of a single variable-energy, but is also much more time consuming to calculate. We present strategies to significantly speed up this calculation for large systems over a large range of energy and order parameter.
Conodont index fossil Hindeodus changxingensis Wang fingers greatest mass extinction event
Metcalfe, I.; Nicoll, R.S.; Wardlaw, B.R.
The marine conodont fossil species, Hindeodus changxingensis Wang, that has a distinctive morphology, is restricted to a very narrow stratigraphic interval essentially from the Permian-Triassic extinction event through the internationally recognized boundary and into the very earliest Triassic. The species is geographically widespread in the Tethyan Region, from Italy to South China, and serves as a characteristic index fossil to reliably identify this short but critical interval that encompasses the greatest mass extinction of life on earth and the boundary between the Paleozoic and Mesozoic Eras. ?? 2007 Nanjing Institute of Geology and Palaeontology, CAS.
An L1-script-transfer-effect fallacy: a rejoinder to Wang et al. (2003).
Yamada, Jun
Do different L1 (first language) writing systems differentially affect word identification in English as a second language (ESL)? Wang, Koda, and Perfetti [Cognition 87 (2003) 129] answered yes by examining Chinese students with a logographic L1 background and Korean students with an alphabetic L1 background for their phonological and orthographic processing skills on English word identification. Such a conclusion is premature, however. We propose that the L1 phonological system (rather than the L1 writing system) of the learner largely accounts for cognitive processes in learning to read a second language (L2). PMID:15147932

NASA Astrophysics Data System (ADS)
Xia, Li-Xin; Abdureyim, Muhammad-Tursun; Liu, Run-Qin; Yu, Sheng-Qing; Guo, Ling; Zhou, Xiang-Ling
In this paper, we propose a super-radiant measurement scheme to achieve Heisenberg limit super-resolving displacement estimation by encoding multiple light momenta into a three-level atomic ensemble with multiple ? photons. And by the Wang's method (Phys. Rev. Lett. 2014, 113, 083601), we use ? coherent pulses to prepare a ?-excitation super-radiant state in a super-position of two timed Dicke states that are ? light momenta apart in the momentum space. The phase difference between these two states induced by a uniform displacement of the atomic ensemble has ? sensitivity. In the end, we introduce two experiments based on Ramsey interferometry in crystal and in ultracold atoms.

Effect of Jian-Pi-Zhi-Dong Decoction on striatal glutamate and γ-aminobutyric acid levels detected using microdialysis in a rat model of Tourette syndrome
Zhang, Wen; Wei, Li; Yu, Wenjing; Cui, Xia; Liu, Xiaofang; Wang, Qian; Wang, Sumei
Background Jian-Pi-Zhi-Dong Decoction (JPZDD) is a dedicated treatment of Tourette syndrome (TS). The balance of neurotransmitters in the cortico-striato-pallido-thalamo-cortical network is crucial to the occurrence of TS and related to its severity. This study evaluated the effect of JPZDD on glutamate (Glu) and γ-aminobutyric acid (GABA) and their receptors in a TS rat model. Materials and methods Rats were divided into four groups (n=12 each). TS was induced in three of the groups by injecting them with 3,3′-iminodipropionitrile for 7 consecutive days. Two model groups were treated with tiapride (Tia) or JPZDD, while the control and the remaining model group were gavaged with saline. Behavior was assessed by stereotypic score and autonomic activity. Striatal Glu and GABA contents were detected using microdialysis. Expressions of N-methyl-D-aspartate receptor 1 and GABAA receptor (GABAAR) were observed using Western blot and real-time polymerase chain reaction. Results Tia and JPZDD groups had decreased stereotypy compared with model rats; however, the JPZDD group showed a larger decrease in stereotypy than the Tia group at a 4-week time point. In a spontaneous activity test, the total distance of the JPZDD and Tia groups was significantly decreased compared with the model group. The Glu levels of the model group were higher than the control group and decreased with Tia or JPZDD treatment. The GABA level was higher in the model group than the control group. Expressions of GABAAR protein in the model group were higher than in the control group. Treatment with Tia or JPZDD reduced the expression of GABAAR protein. In the case of the mRNA expression, only Tia reduced the expression of N-methyl-D-aspartate receptor 1, compared with the model group. Conclusion JPZDD could alleviate impairments in behavior and dysfunctional signaling by downregulating GABAAR in the striatum. We suggest that this acts to maintain the balance of Glu and GABA.

Efficient combination of Wang-Landau and transition matrix Monte Carlo methods for protein simulations.
Ghulghazaryan, Ruben G; Hayryan, Shura; Hu, Chin-Kun
An efficient combination of the Wang-Landau and transition matrix Monte Carlo methods for protein and peptide simulations is described. At the initial stage of simulation the algorithm behaves like the Wang-Landau algorithm, allowing to sample the entire interval of energies, and at the later stages, it behaves like transition matrix Monte Carlo method and has significantly lower statistical errors. This combination allows to achieve fast convergence to the correct values of density of states. We propose that the violation of TTT identities may serve as a qualitative criterion to check the convergence of density of states. The simulation process can be parallelized by cutting the entire interval of simulation into subintervals. The violation of ergodicity in this case is discussed. We test the algorithm on a set of peptides of different lengths and observe good statistical convergent properties for the density of states. We believe that the method is of general nature and can be used for simulations of other systems with either discrete or continuous energy spectrum. PMID:17195159
Performance of Replica-Exchange Wang-Landau Sampling for the 2D Ising Model: A Brief Survey
Zhao, Yiwei; Cheung, Siu Wun; Li, Ying Wai; Eisenbach, Markus
We report a brief performance study of the replica-exchange Wang-Landau algorithm, a recently proposed parallel realization of Wang-Landau sampling, using the 2D Ising model as a test case. The simulation time is found to scale inversely with the square root of the number of subwindows (and thus number of processors) used to span the global parameter space. We also investigate the time profiles for random walkers in dierent subwindows to complete iterations, which will aid the development of and adaptive load-balancing scheme.
Nonequilibrium behaviors of the three-dimensional Heisenberg model in the Swendsen-Wang algorithm
NASA Astrophysics Data System (ADS)
Nonomura, Yoshihiko; Tomita, Yusuke
Recently, it was shown [Y. Nonomura, J. Phys. Soc. Jpn. 83, 113001 (2014), 10.7566/JPSJ.83.113001] that the nonequilibrium critical relaxation of the two-dimensional (2D) Ising model from a perfectly ordered state in the Wolff algorithm is described by stretched-exponential decay, and a universal scaling scheme was found to connect nonequilibrium and equilibrium behaviors. In the present study we extend these findings to vector spin models, and the 3D Heisenberg model could be a typical example. To evaluate the critical temperature and critical exponents precisely using the above scaling scheme, we calculate nonequilibrium ordering from the perfectly disordered state in the Swendsen-Wang algorithm, and we find that the critical ordering process is described by stretched-exponential growth with a comparable exponent to that of the 3D X Y model. The critical exponents evaluated in the present study are consistent with those in previous studies.
``Binless Wang-Landau sampling'' - a multicanonical Monte Carlo algorithm without histograms
NASA Astrophysics Data System (ADS)
Li, Ying Wai; Eisenbach, Markus
Inspired by the very successful Wang-Landau (WL) sampling, we innovated a multicanonical Monte Carlo algorithm to obtain the density of states (DOS) for physical systems with continuous state variables. Unlike the original WL scheme where the DOS is obtained as a numerical array of finite resolution, our algorithm assumes an analytical form for the DOS using a well chosen basis set, with coefficients determined iteratively similar to the WL approach. To avoid undesirable artificial errors caused by the discretization of state variables, we get rid of the use of a histogram for keeping track of the number of visits to energy levels, but store the visited states directly for the fitting of coefficients. This new algorithm has the advantage of producing an analytical expression for the DOS, while the original WL sampling can be readily recovered.

Replica-exchange Wang-Landau simulations of the H0P lattice protein model
NASA Astrophysics Data System (ADS)
Shi, Guangjie; Wüst, Thomas; Li, Ying Wai; Landau, David P.
The hydrophobic-polar (HP) lattice protein model has been the subject of intensive investigation in an effort to aid our understanding of protein folding. However, the high ground state degeneracies caused by its simplification stands in contrast to the generally unique native states of natural proteins. Here we proposed a simple modification, by introducing a new type of ``neutral'' monomer, 0, i.e. neither hydrophobic nor polar, thus rendering the model more realistic without increasing the difficulties of sampling significantly. With the replica exchange Wang-Landau (REWL) scheme we investigated several widely studied HP proteins and their H0P counterparts. Dramatic differences in both ground state and thermodynamic properties have been found. For example, the H0P version of Crambin shows more clear two-step folding and 3 order of magnitudes less ground state degeneracy than its HP counterpart. Supported by NSF.
Thermodynamics and structural properties of a confined HP protein determined by Wang-Landau simulation
Pattanasiri, Busara; Li, Ying Wai; Landau, David P; Wuest, Thomas; Triampo, Wannapong
We used Wang-Landau sampling with inventive Monte Carlo moves to study the influence of surface characteristics on physical behavior of a hydrophobic-polar (HP) lattice protein model confined between two attractive surfaces. Three types of surfaces, namely, surfaces that attract: (a) all monomers; (b) only P monomers; or (c) only H monomers, have been considered. After obtaining the densities of states, we then found the thermodynamic and structural quantities, such as specific heat, number of surface contacts, and number of hydrophobic interaction pairs. A few conformational transitions , e.g., debridging process and hydrophobic core formation, can be identified based on an analysis of these quantities. Depending on the surface types, these transitions take place at different temperatures, while the ground state configurations show structural variations. These scenarios are confirmed by snapshots of typical states of the systems.

Komura, Yukihiro
We present sample OpenACC programs of the Swendsen-Wang multi-cluster spin flip algorithm. OpenACC is a directive-based programming model for accelerators without requiring modification to the underlying CPU code itself. In this paper, we deal with the classical spin models as with the sample CUDA programs (Komura and Okabe, 2014), that is, two-dimensional (2D) Ising model, three-dimensional (3D) Ising model, 2D Potts model, 3D Potts model, 2D XY model and 3D XY model. We explain the details of sample OpenACC programs and compare the performance of the present OpenACC implementations with that of the CUDA implementations for the 2D and 3D Ising models and the 2D and 3D XY models.

Validation of Community Models: 2. Development of a Baseline, Using the Wang-Sheeley-Arge Model
NASA Technical Reports Server (NTRS)
MacNeice, Peter
This paper is the second in a series providing independent validation of community models of the outer corona and inner heliosphere. Here I present a comprehensive validation of the Wang-Sheeley-Arge (WSA) model. These results will serve as a baseline against which to compare the next generation of comparable forecasting models. The WSA model is used by a number of agencies to predict Solar wind conditions at Earth up to 4 days into the future. Given its importance to both the research and forecasting communities, it is essential that its performance be measured systematically and independently. I offer just such an independent and systematic validation. I report skill scores for the model's predictions of wind speed and interplanetary magnetic field (IMF) polarity for a large set of Carrington rotations. The model was run in all its routinely used configurations. It ingests synoptic line of sight magnetograms. For this study I generated model results for monthly magnetograms from multiple observatories, spanning the Carrington rotation range from 1650 to 2074. I compare the influence of the different magnetogram sources and performance at quiet and active times. I also consider the ability of the WSA model to forecast both sharp transitions in wind speed from slow to fast wind and reversals in the polarity of the radial component of the IMF. These results will serve as a baseline against which to compare future versions of the model as well as the current and future generation of magnetohydrodynamic models under development for forecasting use.
Generic transition hierarchies of lattice HP protein adsorption: A Wang-Landau study
NASA Astrophysics Data System (ADS)
Li, Ying Wai; Landau, D. P.; Wüst, T.
We have applied Wang-Landau sampling with appropriate trial movesootnotetextT. W"ust and D. P. Landau, Phy. Rev. Lett. 102, 178101 (2009). to investigate the thermodynamics and structural properties of the HP lattice protein modelootnotetextK. A. Dill, Biochemistry 24, 1501 (1985). interacting with an attractive substrate. The conformational ``phase transitions'' of several benchmark HP sequences have been identified by a comprehensive canonical analysis of the specific heat and structural observables, e. g. radius of gyration and thermal derivatives of number of surface contacts. Three major ``transitions'': adsorption, hydrophobic core formation, and ``flattening'' of adsorbed structures, are observed. Depending on the surface attractive strength relative to the intra-protein attraction among the H monomers, these processes take place in a different order upon cooling. We identify a small number of generic categories that are sufficient to classify the folding hierarchies for different HP chains consisting of assorted sequences and chain lengths, regardless of the monomer type that the surface attracts. We thus believe that this classification scheme is generally applicable to lattice protein adsorption problems.
Temperature-dependent phase transition of ferroelectric perovskites: A Wang-Landau-DFT approach

Yuk, Simuck; Li, Ying Wai; Eisenbach, Markus; Cooper, Valentino
Since the discovery of ferroelectricity in perovskite oxides, considerable efforts have been devoted to understanding their phase transition behaviors in terms of temperature, pressure, and composition. Such materials have regularly been used in transducer and actuator applications. As our first step to make accurate predictions of the crystal phases of more complex oxides such as Pb(ZrxTi1-x) O3, we have used the Wang-Landau (WL) algorithm and density functional theory (DFT) to examine the temperature-dependent phase transition of PbTiO3, BaTiO3, and KNbO3. DFT was employed to evaluate the energetics of important crystal-structure candidates, which were later used as the input for WL algorithm. In addition, we examine how the choice of exchange-correlation functionals affects our predictions of the relevant phase transition temperatures.

Enhanced von Weizsäcker Wang-Govind-Carter kinetic energy density functional for semiconductors
Shin, Ilgyou; Carter, Emily A.
We propose a new form of orbital-free (OF) kinetic energy density functional (KEDF) for semiconductors that is based on the Wang-Govind-Carter (WGC99) nonlocal KEDF. We enhance within the latter the semi-local von Weizsäcker KEDF term, which is exact for a single orbital. The enhancement factor we introduce is related to the extent to which the electron density is localized. The accuracy of the new KEDF is benchmarked against Kohn-Sham density functional theory (KSDFT) by comparing predicted energy differences between phases, equilibrium volumes, and bulk moduli for various semiconductors, along with metal-insulator phase transition pressures. We also compare point defect and (100) surface energies in silicon for a broad test of its applicability. This new KEDF accurately reproduces the exact non-interacting kinetic energy of KSDFT with only one additional adjustable parameter beyond the three parameters in the WGC99 KEDF; it exhibits good transferability between semiconducting to metallic silicon phases and between various III-V semiconductors without parameter adjustment. Overall, this KEDF is more accurate than previously proposed OF KEDFs (e.g., the Huang-Carter (HC) KEDF) for semiconductors, while the computational efficiency remains at the level of the WGC99 KEDF (several hundred times faster than the HC KEDF). This accurate, fast, and transferable new KEDF holds considerable promise for large-scale OFDFT simulations of metallic through semiconducting materials.
Wang-Landau sampling of the interplay between surface adsorption and folding of HP lattice proteins
Li, Ying Wai; Wuest, Thomas; Landau, David P
Generic features associated with the adsorption of proteins on solid surfaces are reviewed within the framework of the hydrophobic-polar (HP) lattice protein model. The thermodynamic behavior and structural properties of various HP protein sequences interacting with attractive surfaces have been studied using extensive Wang-Landau sampling with different types of surfaces, each of which attracts either: all monomers, only hydrophobic (H) monomers, or only polar (P) monomers, respectively. Consequently, different types of folding behavior occur for varied surface strengths. Analysis of the combined patterns of various structural observables, e.g., the derivatives of the numbers of interaction contacts, together with the specific heat, leads to the identification of fundamental categories of folding and transition hierarchies. We also inferred a connection between the transition categories and the relative surface strengths, i.e., the ratios of the surface attractive strengths to the intra-chain attraction among H monomers. We thus believe that the folding hierarchies and identification scheme are generic for different HP sequences interacting with attractive surfaces, regardless of the chain length, sequence, or surface attraction.
Somatic embryogenesis and enhanced shoot organogenesis in Metabriggsia ovalifolia W. T. Wang.
Ouyang, Yao; Chen, Yulu; Lü, Jinfeng; Teixeira da Silva, Jaime A; Zhang, Xinhua; Ma, Guohua
An efficient protocol providing a dual regeneration pathway via direct shoot organogenesis and somatic embryogenesis for an endangered species, Metabriggsia ovalifolia W. T. Wang, was established from leaf explants. When applied at 2.5 μM, the cytokinins 6-benzyladenine (BA) or thidiazuron (TDZ) and the auxins indole-3-butyric acid (IBA), α-naphthaleneacetic acid (NAA) and indole-3-acetic acid (IAA) could induce shoots when on basal Murashige and Skoog (MS) medium. BA and TDZ could induce more adventitious shoots (19.1 and 31.2/explant, respectively) than NAA (4.6/explant), IBA (5.7/explant) or IAA (6.4/explant). BA and TDZ at 5-10 μM could induce both shoots and somatic embryos. A higher concentration of TDZ (25 μM) induced only somatic embryos (39.8/explant). The same concentration of BA induced both adventitious shoots (23.6/explant) and somatic embryos (9.7/explant). Thus, somatic embryogenesis in this plant needs a high cytokinin concentration (BA; TDZ), as evidenced by histology. Somatic embryos germinated easily when left on the same media, but formed adventitious roots in two weeks on MS supplemented with 0.5 μM NAA, 0.5 μM IBA and 0.1% activated charcoal. Over 93% of plantlets survived following acclimatization and transfer to a mixture of sand and vermiculite (1:1, v/v) in trays. PMID:27090564

Efficient generation of peptide hydrazides via direct hydrazinolysis of Peptidyl-Wang-TentaGel resins.
Bello, Claudia; Kikul, Frauke; Becker, Christian F W
Peptide hydrazides are valuable building blocks in peptide and protein chemistry, e.g. as precursors of peptide thioesters that allow the preparation of these important intermediates under mild conditions. Additional robust and versatile methods for the generation of peptide hydrazides from standard solid supports are therefore highly desired in order to facilitate access to peptide thioester via Fmoc-based SPPS. Here, the efficient generation of peptide hydrazides from conventional 4-hydroxymethyl phenol Wang-TentalGel peptidyl resins is described. Direct hydrazinolysis of a 19mer mucin1 peptide gives the protected peptide hydrazide in excellent yields. Testing a series of octapeptides carrying the 20 common proteinogenic amino acids at their C-terminus led to preparation of all corresponding peptide hydrazides in very good to excellent yields and purities. The available set of octapeptides allowed analyzing the influence of the nature of the C-terminal amino acid and of the solvent on the hydrazinolysis reaction. Furthermore, the compatibility of the method with posttranslational modifications (here glycosylation) and with potentially sensitive functional groups in amino acid side chains makes this approach a viable alternative for obtaining peptide hydrazides. It combines the advantages of a straightforward synthesis with stereochemical stability and flexibility, as it provides easy access to the peptide acid and the peptide thioester (via the hydrazide) from the same solid support.

Applications of Wang-Landau sampling to determine phase equilibria in complex fluids
NASA Astrophysics Data System (ADS)
Ganzenmüller, Georg; Camp, Philip J.
Applications of the Wang-Landau algorithm for simulating phase coexistence at fixed temperature are presented. The number density is sampled using either volume scaling or particle insertion/deletion. The resulting algorithms, while being conceptually easy, are of comparable efficiency to existing multicanonical methods but with the advantage that neither the chemical potential nor the pressure at phase coexistence has to be estimated in advance of the simulation. First, we benchmark the algorithm against literature results for the vapor-liquid transition in the Lennard-Jones fluid. We then demonstrate the general applicability of the algorithm by studying vapor-liquid coexistence in two examples of complex fluids: charged soft spheres, which exhibit a transition similar to that in the restricted primitive model of ionic fluids, being characterized by strong ion pairing in the vapor phase; and Stockmayer fluids with high dipole strengths, in which the constituent particles aggregate to form chains, and for which the very existence of a transition has been widely debated. Finally, we show that the algorithm can be used to locate a weak isotropic-nematic transition in a fluid of Gay-Berne mesogens.

Applications of the Wang-Landau algorithm for simulating phase coexistence at fixed temperature are presented. The number density is sampled using either volume scaling or particle insertion/deletion. The resulting algorithms, while being conceptually easy, are of comparable efficiency to existing multicanonical methods but with the advantage that neither the chemical potential nor the pressure at phase coexistence has to be estimated in advance of the simulation. First, we benchmark the algorithm against literature results for the vapor-liquid transition in the Lennard-Jones fluid. We then demonstrate the general applicability of the algorithm by studying vapor-liquid coexistence in two examples of complex fluids: charged soft spheres, which exhibit a transition similar to that in the restricted primitive model of ionic fluids, being characterized by strong ion pairing in the vapor phase; and Stockmayer fluids with high dipole strengths, in which the constituent particles aggregate to form chains, and for which the very existence of a transition has been widely debated. Finally, we show that the algorithm can be used to locate a weak isotropic-nematic transition in a fluid of Gay-Berne mesogens. PMID:17949170
Phase transition of a single star polymer: A Wang-Landau sampling study
NASA Astrophysics Data System (ADS)
Wang, Zilu; He, Xuehao
Star polymers, as an important class of nonlinear macromolecules, process special thermodynamic properties for the existence of a common connecting point. The thermodynamic transitions of a single star polymer are systematically studied with the bond fluctuation model using Wang-Landau sampling techniques. A new analysis method employing the shape factor is proposed to locate the coil-globule (CG) and liquid-crystal (LC) transitions, which shows a higher efficiency and accuracy than the canonical specific heat function. The LC transition temperature is found to obey the identical scaling law as the linear polymers. However, the CG transition temperature shifts towards the LC transition with the increasing of the arm number. The reason is that for the star polymer a lower temperature is needed for the attractive force to overcome the excluded volume effect of the polymer chain because of its high arm density. This work clearly proves the structural distinction of the linear and star polymers can only affect the CG transition while has no influence on the LC transition.
Nonconvergence of the Wang-Landau algorithms with multiple random walkers
NASA Astrophysics Data System (ADS)
Belardinelli, R. E.; Pereyra, V. D.
This paper discusses some convergence properties in the entropic sampling Monte Carlo methods with multiple random walkers, particularly in the Wang-Landau (WL) and 1 /t algorithms. The classical algorithms are modified by the use of m -independent random walkers in the energy landscape to calculate the density of states (DOS). The Ising model is used to show the convergence properties in the calculation of the DOS, as well as the critical temperature, while the calculation of the number π by multiple dimensional integration is used in the continuum approximation. In each case, the error is obtained separately for each walker at a fixed time, t ; then, the average over m walkers is performed. It is observed that the error goes as 1 /√{m } . However, if the number of walkers increases above a certain critical value m >mx , the error reaches a constant value (i.e., it saturates). This occurs for both algorithms; however, it is shown that for a given system, the 1 /t algorithm is more efficient and accurate than the similar version of the WL algorithm. It follows that it makes no sense to increase the number of walkers above a critical value mx, since it does not reduce the error in the calculation. Therefore, the number of walkers does not guarantee convergence.

NASA Astrophysics Data System (ADS)
Vogel, Thomas; Perez, Danny; Junghans, Christoph
We show direct formal relationships between the Wang-Landau iteration [PRL 86, 2050 (2001)], metadynamics [PNAS 99, 12562 (2002)] and statistical temperature molecular dynamics [PRL 97, 050601 (2006)], the major Monte Carlo and molecular dynamics work horses for sampling from a generalized, multicanonical ensemble. We aim at helping to consolidate the developments in the different areas by indicating how methodological advancements can be transferred in a straightforward way, avoiding the parallel, largely independent, developments tracks observed in the past.

Widespread use of synthetic pesticides has resulted in the development of insecticide-resistant populations of pests and harmful effects on human health and the environment. There is a need to identify alternative pest management strategies to reduce our reliance on conventional chemical pesticides. In recent years the use of botanical pesticides for protecting crops from insect pests has assumed greater importance. Methanol extract of Alangium salvifolium (L.f.) Wang has potential insecticidal activity against Spodoptera litura Fab. The active fractions were identified through chromatographic techniques as F-IV (Rf value=0.45) and F-VI (Rf value=0.63) and were subjected to GC-MS (GCMATE II). Fifty, 100 and 200ppm of active fractions were applied to fourth instar larvae and the mortality increased with higher concentrations. Relative consumption rate, relative growth rate, efficiency of conversion of ingested food and efficiency of conversion of digested food values all decreased in treated larvae, but approximate digestibility rate increased after treatment. The hydrolytic enzymes, such as acid phosphatase, alkaline phosphatase and the glycolytic enzyme lactate dehydrogenase were inhibited in treated larvae compared with controls. The histopathology study revealed that the epithelial columnar cells were enlarged, completely atrophied; intercellular spaces were swollen, and also noted a cytoplasmic ooze of cell material that mixed with food column. The present study clearly showed the active fractions from A. salvifolium as potential botanicals to control the larvae of S. litura. This is the first report for nutritional indices, enzymatic activities and histological effects of A. salvifolium chemical constituents against S. litura. Thus probably, this will be used as an alternative for synthetic pesticides against the polyphagous pest like S. litura. PMID:26778440

Calculation of the Curie temperature of Ni using first principles based Wang-Landau Monte-Carlo
NASA Astrophysics Data System (ADS)
Eisenbach, Markus; Yin, Junqi; Li, Ying Wai; Nicholson, Don
We combine constrained first principles density functional with a Wang-Landau Monte Carlo algorithm to calculate the Curie temperature of Ni. Mapping the magnetic interactions in Ni onto a Heisenberg like model to underestimates the Curie temperature. Using a model we show that the addition of the magnitude of the local magnetic moments can account for the difference in the calculated Curie temperature. For ab initio calculations, we have extended our Locally Selfconsistent Multiple Scattering (LSMS) code to constrain the magnitude of the local moments in addition to their direction and apply the Replica Exchange Wang-Landau method to sample the larger phase space efficiently to investigate Ni where the fluctuation in the magnitude of the local magnetic moments is of importance equal to their directional fluctuations. We will present our results for Ni where we compare calculations that consider only the moment directions and those including fluctuations of the magnetic moment magnitude on the Curie temperature.

Sann-Joong-Kuey-Jian-Tang induces autophagy in HepG2 cells via regulation of the phosphoinositide-3 kinase/Akt/mammalian target of rapamycin and p38 mitogen-activated protein kinase pathways
Sann-Joong-Kuey-Jian-Tang (SJKJT), a traditional Chinese medicine, was previously reported to induce autophagy and inhibit the proliferation of the human HepG2 hepatocellular carcinoma cell line via an extrinsic pathway. In the present study, the effects of SJKJT-induced autophagy and the cytotoxic mechanisms mediating these effects were investigated in HepG2 cells. The cytotoxicity of SJKJT in the HepG2 cells was evaluated using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The results demonstrated that the half-maximal inhibitory concentration of SJKJT was 2.91 mg/ml at 24 h, 1.64 mg/ml at 48 h and 1.26 mg/ml at 72 h. The results of confocal fluorescence microscopy indicated that SJKJT resulted in the accumulation of green fluorescent protein-LC3 and vacuolation of the cytoplasm. Flow cytometric analysis revealed the accumulation of acidic vesicular organelles. Furthermore, western blot analysis, used to determine the expression levels of autophagy-associated proteins, demonstrated that the HepG2 cells treated with SJKJT exhibited LC3B-I/LC3B-II conversion, increased expression levels of Beclin, Atg-3 and Atg-5 and reduced expression levels of p62 and decreased signaling of the phosphoinositide-3 kinase/Akt/mammalian target of rapamycin and the p38 mitogen-activated protein kinase pathways. Taken together, these findings may assist in the development of novel chemotherapeutic agents for the treatment of malignant types of liver cancer. PMID:25847489
Comments on 'A structure-preserving method for the quaternion LU decomposition in quaternionic quantum theory' by Minghui Wang and Wenhao Ma
NASA Astrophysics Data System (ADS)
Sangwine, Stephen J.
Claims were made in an article by Wang and Ma in 2013 that they had devised an algorithm for the quaternion LU decomposition that was significantly faster than the LU decomposition implemented in the Quaternion Toolbox for MATLAB (QTFM). These claims have been tested and found to be unsupported by MATLAB code supplied to the author by Wang and Ma. The author's tests are presented, and test code made available as supplementary material. It is found that not only is the QTFM code faster, but that Wang and Ma's algorithm has run-time that scales with the square of the size of the matrix, whereas the algorithm in QTFM has run time approximately linear in matrix size. These findings are consistent with an inspection of the code.
All-atom simulation study of protein PTH(1-34) by using the Wang-Landau sampling method
NASA Astrophysics Data System (ADS)
Kim, Seung-Yeon; Kwak, Wooseop
We perform simulations of the N-terminal 34-residue protein fragment PTH(1-34), consisting of 581 atoms, of the 84-residue human parathyroid hormone by using the all-atom ECEPP/3 force field and the Wang-Landau sampling method. Through a massive high-performance computation, the density of states and the partition function Z( T), as a continuous function of T, are obtained for PTH(1-34). From the continuous partition function Z( T), the partition function zeros of PTH(1-34) are evaluated for the first time. From both the specific heat and the partition function zeros, two characteristic transition temperatures are obtained for the all-atom protein PTH(1-34). The higher transition temperature T 1 and the lower transition temperature T 2 of PTH(1-34) can be interpreted as the collapse temperature T θ and the folding temperature T f , respectively.

Identification of chemical constituents in traditional Chinese medicine formula using HPLC coupled with linear ion trap-Orbitrap MS from high doses of medicinal materials to equivalent doses of formula: Study on Xiang-Sha-Liu-Jun-Zi-Jia-Jian granules.
Wang, Fengyun; Zhang, Qingqing; Lu, Zhiwei; Wang, Qing; Wang, Meiling; Liu, Yuehong; Fu, Shuang; Gao, Xiaoyan; Tang, Xudong
High-resolution mass spectrometry has been a powerful tool for the research of chemical constituents in traditional Chinese medicine (TCM) formulas. However, the chromatographic peaks were difficult to discriminate clearly in data collection or analysis because of the complexity and the greatly different content of the constituents in TCM formula, which increased the difficulty of identification. In this study, a high-performance liquid chromatography coupled with linear ion trap-Orbitrap mass spectrometry based strategy focused on the comprehensive identification of TCM formula constituents was developed. Identification was carried out from a high dose of medicinal materials to equivalent dose of formula. Meanwhile, combined with mass spectrometry data, chromatographic behaviors, reference standards and previous reports, the identification of constituents in Xiang-Sha-Liu-Jun-Zi-Jia-Jian granules was described. 169 compounds were unambiguously or tentatively characterized, mainly including flavonoids, alkaloids, triterpenic acids, triterpene saponins, lactones, sesquiterpenoids and some other compounds. Among them, 11 compounds were unambiguously confirmed by comparing with reference standards. These results demonstrated that the method was effective and reliable for comprehensive identification of constituents of Xiang-Sha-Liu-Jun-Zi-Jia-Jian granules extracts and reveal the material basis of its therapeutic effects. This strategy might propose a research idea for the characterization of multi-constituents in TCM formula. PMID:26935761
Public health impact of disease-behavior dynamics. Comment on "Coupled disease-behavior dynamics on complex networks: A review" by Z. Wang et al.
NASA Astrophysics Data System (ADS)
Wells, Chad R.; Galvani, Alison P.
In a loop of dynamic feedback, behavior such as the decision to vaccinate, hand washing, or avoidance influences the progression of the epidemic, yet behavior is driven by the individual's and population's perceived risk of infection during an outbreak. In what we believe will become a seminal paper that stimulates future research as well as an informative teaching aid, Wang et. al. comprehensively review methodological advances that have been used to incorporate human behavior into epidemiological models on the effects of coupling disease transmission and behavior on complex social networks [1]. As illustrated by the recent outbreaks of measles and Middle Eastern Respiratory Syndrome (MERS), here we highlight the importance of coupling behavior and disease transmission that Wang et al. address.
Reply to Comment on ``Effects of fast and slow solar wind on the correlations between interplanetary medium and geomagnetic activity'' by C. B. Wang and J. K. Chao
NASA Astrophysics Data System (ADS)
Ballatore, Paola
The paper [2002] (the paper commented) shows that the statistical significance of the correlations between the interplanetary parameters and the geomagnetic indices (Kp or Dst) is generally less significant during the fastest solar wind. On the other hand, at these fast solar wind periods, the significance of the Kp versus Dst correlation is equal to or higher than during slower solar wind. These results, together with further observations related to substorm periods and with previously published findings, are interpreted in terms of a difference in the interplanetary-magnetospheric coupling for solar wind faster or slower than a certain threshold (identified between about 500 and 600 km/s). Specifically, it is suggested that a possible linear approximation of the geomagnetic-interplanetary coupling is more appropriate during solar wind speed (Vsw) slower than this threshold, being nonlinear processes more dominant during the fastest speeds. This reply highlights that the correlation coefficients shown by [2003] are in agreement with these findings. In addition, Wang and Chao show that the statistical significance of the difference between the correlation coefficients for Vsw ≥ 550 km/s and those for Vsw < 550 km/s would indicate that the interplanetary-geomagnetic correlations during the fastest speeds are not significantly different from those at slower Vsw ranges. Here we give evidence of the fact that according to the common definition of this parameter, the calculation of the significance of the difference between two correlation coefficients made by Wang and Chao is wrong. Moreover, Wang and Chao recalculate the correlations between the interplanetary parameters and the ΔDst instead of Dst; in fact they note that the time derivative of this index (not the index itself) is driven by the interplanetary medium. Here we note that on the contrary, they show that the correlation coefficients between interplanetary parameters and Dst are larger than those
Improved CUDA programs for GPU computing of Swendsen-Wang multi-cluster spin flip algorithm: 2D and 3D Ising, Potts, and XY models

Komura, Yukihiro; Okabe, Yutaka
We present new versions of sample CUDA programs for the GPU computing of the Swendsen-Wang multi-cluster spin flip algorithm. In this update, we add the method of GPU-based cluster-labeling algorithm without the use of conventional iteration (Komura, 2015) to those programs. For high-precision calculations, we also add a random-number generator in the cuRAND library. Moreover, we fix several bugs and remove the extra usage of shared memory in the kernel functions.
Cytotoxicity enhancement in MDA-MB-231 cells by the combination treatment of tetrahydropalmatine and berberine derived from Corydalis yanhusuo W. T. Wang
Zhao, Yan; Gao, Jian-Li; Ji, Jian-Wei; Gao, Min; Yin, Qiao-Shan; Qiu, Qiao-Li; Wang, Chuan; Chen, Shu-Zhan; Xu, Juan; Liang, Ren-Shang; Cai, Yan-Zi; Wang, Xia-Fei
Aim: Our previous works have demonstrated that Chinese herb medicine yanhusuo (Corydalis yanhusuo W. T. Wang) has strong anti-cancer proliferation effect in MDA-MB-231 cells. The goal of this study was to find out the synergic cytotoxicity effect of three natural compounds, tetrahydropalmatine (THP), berberine (Ber), and dehydrocorydaline (DHC), isolated from C. yanhusuo W. T. Wang. Materials and Methods: The IC50 of THP Ber and DHC in single use, as well as in combination use at fixed ratios and doses was measured by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay. Isobologram, combination index and modified coefficient of drug interaction (CDI) methods were used for evaluation the combination effects of THF! Ber, and DHC in different ratio and concentration. Results: The results indicated that the combination of THP and Ber shown the strongest anti-cancer cell proliferation effect at the ratio of 2:3 (Ber: THF the average CDI value was 0.5795). DHC and THP have additive cytotoxicity in MDA-MB-231 cells. However, there wasn't any synergistic effect between Ber and DHC, and it even exhibited antagonistic effect when the percentage of DHC was >50%. Conclusion: Our findings suggested that the combination of THP and Ber might be beneficial for anti-proliferation of MDA-MB-231 breast cancer cells through a significant synergy effect. PMID:26401350
First-order phase transition and tricritical scaling behavior of the Blume-Capel model: A Wang-Landau sampling approach.
Kwak, Wooseop; Jeong, Joohyeok; Lee, Juhee; Kim, Dong-Hee
We investigate the tricritical scaling behavior of the two-dimensional spin-1 Blume-Capel model by using the Wang-Landau method of measuring the joint density of states for lattice sizes up to 48×48 sites. We find that the specific heat deep in the first-order area of the phase diagram exhibits a double-peak structure of the Schottky-like anomaly appearing with the transition peak. The first-order transition curve is systematically determined by employing the method of field mixing in conjunction with finite-size scaling, showing a significant deviation from the previous data points. At the tricritical point, we characterize the tricritical exponents through finite-size-scaling analysis including the phenomenological finite-size scaling with thermodynamic variables. Our estimation of the tricritical eigenvalue exponents, yt=1.804(5), yg=0.80(1), and yh=1.925(3), provides the first Wang-Landau verification of the conjectured exact values, demonstrating the effectiveness of the density-of-states-based approach in finite-size scaling study of multicritical phenomena.

Grateloupia ramosa Wang & Luan sp. nov. (Halymeniaceae, Rhodophyta), a new species from China based on morphological evidence and comparative rbcL sequences
NASA Astrophysics Data System (ADS)
Cao, Cuicui; Liu, Miao; Guo, Shaoru; Zhao, Dan; Luan, Rixiao; Wang, Hongwei
Grateloupia ramosa Wang & Luan sp. nov. (Halymeniaceae, Rhodophyta) is newly described from Hainan Province, southern China. The organism has the following morphological features: (1) purplish red, cartilaginous and lubricous thalli 5-10 cm in height; (2) compressed percurrent axes bearing abundant branches with opposite arrangement; (3) claw-like apices on top, constricted to 2-4 cm at the base; (4) cortex consisting of 3-6 layers of elliptical or anomalous cells and a medulla covered by compact medullary filaments; (5) reproductive structures distributed throughout the thallus, especially centralized at the bottom of the end portion of the branches; and (6) 4-celled Carpogonial branches and 3-celled auxiliary-cell branches, both of the Grateloupia-type. The morphological diff erences were supported by molecular phylogenetics based on ribulose-1, 5-bisphosphate carboxylase/oxygenase ( rbcL) gene sequence analysis. There was only a 1 bp divergence between specimens collected from Wenchang and Lingshui of Hainan province. The new species was embedded in the large Grateloupia clade of the Halymeniaceae. The pairwise distances between G. ramosa and other species within Grateloupia ranged from 26 to 105 bp, within pairwise distances of 13-111 bp between species of the large genus Grateloupia in Halymeniaceae. Thus, we propose this new species as G. ramosa Wang & Luan sp. nov.
Folding-unfolding transition in the mini-protein villin headpiece (HP35): An equilibrium study using the Wang-Landau algorithm
NASA Astrophysics Data System (ADS)
Singh, Priya; Sarkar, Subir K.; Bandyopadhyay, Pradipta
A computational study, using the Wang-Landau algorithm, is carried out for the 35 residue mini-protein villin headpiece (HP35) to investigate some equilibrium aspects of its folding-unfolding transition in water. The force field used is ECEPP/3 and a solvent-accessible surface area method is used to describe the interaction with water. The density of states and the conditional probabilities of some physically interesting geometrical descriptors of the molecule at various energies are calculated by analyzing the high-statistics data generated by the simulations. All canonical ensemble averages are subsequently calculated by using these data. The computed quantities include specific heat, radius of gyration, number of native contacts, number of helical residues and the potential of mean force for three pairs of geometric descriptors. High precision and a systematic check on the convergence of the computation are the two key points of our methodology.
Simple deterministic models and applications. Comment on "Coupled disease-behavior dynamics on complex networks: A review" by Z. Wang et al.
NASA Astrophysics Data System (ADS)
Yang, Hyun Mo
Currently, discrete modellings are largely accepted due to the access to computers with huge storage capacity and high performance processors and easy implementation of algorithms, allowing to develop and simulate increasingly sophisticated models. Wang et al. [7] present a review of dynamics in complex networks, focusing on the interaction between disease dynamics and human behavioral and social dynamics. By doing an extensive review regarding to the human behavior responding to disease dynamics, the authors briefly describe the complex dynamics found in the literature: well-mixed populations networks, where spatial structure can be neglected, and other networks considering heterogeneity on spatially distributed populations. As controlling mechanisms are implemented, such as social distancing due 'social contagion', quarantine, non-pharmaceutical interventions and vaccination, adaptive behavior can occur in human population, which can be easily taken into account in the dynamics formulated by networked populations.

Wang-Landau density of states based study of the folding-unfolding transition in the mini-protein Trp-cage (TC5b)
Singh, Priya; Sarkar, Subir K.; Bandyopadhyay, Pradipta
We present the results of a high-statistics equilibrium study of the folding/unfolding transition for the 20-residue mini-protein Trp-cage (TC5b) in water. The ECEPP/3 force field is used and the interaction with water is treated by a solvent-accessible surface area method. A Wang-Landau type simulation is used to calculate the density of states and the conditional probabilities for the various values of the radius of gyration and the number of native contacts at fixed values of energy—along with a systematic check on their convergence. All thermodynamic quantities of interest are calculated from this information. The folding-unfolding transition corresponds to a peak in the temperature dependence of the computed specific heat. This is corroborated further by the structural signatures of folding in the distributions for radius of gyration and the number of native contacts as a function of temperature. The potentials of mean force are also calculated for these variables, both separately and jointly. A local free energy minimum, in addition to the global minimum, is found in a temperature range substantially below the folding temperature. The free energy at this second minimum is approximately 5 k{sub B}T higher than the value at the global minimum.
Critical nonequilibrium relaxation in the Swendsen-Wang algorithm in the Berezinsky-Kosterlitz-Thouless and weak first-order phase transitions
NASA Astrophysics Data System (ADS)
Nonomura, Yoshihiko; Tomita, Yusuke
Recently we showed that the critical nonequilibrium relaxation in the Swendsen-Wang algorithm is widely described by the stretched-exponential relaxation of physical quantities in the Ising or Heisenberg models. Here we make a similar analysis in the Berezinsky-Kosterlitz-Thouless phase transition in the two-dimensional (2D) X Y model and in the first-order phase transition in the 2D q =5 Potts model and find that these phase transitions are described by the simple exponential relaxation and power-law relaxation of physical quantities, respectively. We compare the relaxation behaviors of these phase transitions with those of the second-order phase transition in the three- and four-dimensional X Y models and in the 2D q -state Potts models for 2 ≤q ≤4 and show that the species of phase transitions can be clearly characterized by the present analysis. We also compare the size dependence of relaxation behaviors of the first-order phase transition in the 2D q =5 and 6 Potts models and propose a quantitative criterion on "weakness" of the first-order phase transition.
From polymers to proteins: the effect of side chains and broken symmetry on the formation of secondary structures within a Wang-Landau approach.
Škrbić, Tatjana; Badasyan, Artem; Hoang, Trinh Xuan; Podgornik, Rudolf; Giacometti, Achille
We use a micro-canonical Wang-Landau technique to study the equilibrium properties of a single flexible homopolymer where consecutive monomers are represented by impenetrable hard spherical beads tangential to each other, and non-consecutive monomers interact via a square-well potential. To mimic the characteristics of a protein-like system, the model is then refined in two different directions. Firstly, by allowing partial overlap between consecutive beads, we break the spherical symmetry and thus provide a severe constraint on the possible conformations of the chain. Alternatively, we introduce additional spherical beads at specific positions in the direction normal to the backbone, to represent the steric hindrance of the side chains in real proteins. Finally, we consider also a combination of these two ingredients. In all three systems, we obtain the full phase diagram in the temperature-interaction range plane and find the presence of helicoidal structures at low temperatures in the intermediate range of interactions. The effect of the range of the square-well attraction is highlighted, and shown to play a role similar to that found in simple liquids and polymers. Perspectives in terms of protein folding are finally discussed. PMID:27137225
Scaling behavior can be tricky: Comment on "Universal scaling for the dilemma strength in evolutionary games" by Z. Wang et al.
NASA Astrophysics Data System (ADS)
Hui, Pak Ming; Xu, Chen
Evolutionary game theory is a powerful tool for studying the emergence of cooperation among competing individuals [1]. Popularly studied games include the prisoner's dilemma [2], snowdrift game [3] and stag hunt game [4]. They have been extensively studied for the extent of cooperative behavior under different dilemma strengths. Generally, the games can be defined by a 2 × 2 matrix and thus four payoff elements, T, R, P, and S, for the possible payoffs to players when they use pure strategies against each other. Detailed definitions of the four payoffs are given in the review by Wang et al. [5]. For simplicity, it is often the case that fewer parameters are invoked, e.g. a single parameter [3] and more generally two parameters [6]. Generally speaking, reducing the number of parameters has the effect of restricting the system to a certain subspace of the unreduced case. In addition, the spatial structures, such as a well-mixed population or a population forming a complex network, that govern the competing relationship and environment of the agents, and the evolutionary rules, that govern how agents update their strategies, are vital in determining how cooperation evolves, as well documented in the references of [5].
An isoquinoline alkaloid from the Chinese herbal plant Corydalis yanhusuo W.T. Wang inhibits P-glycoprotein and multidrug resistance-associate protein 1.
Lei, Yu; Tan, Juan; Wink, Michael; Ma, Yonggang; Li, Na; Su, Guannan
Overexpression of P-glycoprotein (P-gp) and multidrug resistance-associate protein 1 (MRP1) is a major mechanism leading to multidrug resistance (MDR) of cancer cells. These transporters expel anti-cancer drugs and greatly impair therapeutic efficacy of chemotherapy. A Chinese herbal plant Yanhusuo (Corydalis yanhusuo W.T. Wang, YHS) is frequently used in functional food and traditional Chinese medicine to improve the efficacy of chemotherapy. The objective of this work was to study effects of glaucine, an alkaloid component of YHS, on P-gp and MRP1 in resistant cancer cells. The resistant cancer cell line, MCF-7/ADR and corresponding parental sensitive cells were employed to determine reversal properties of glaucine. Glaucine inhibits P-gp and MRP1-mediated efflux and activates ATPase activities of the transporters, indicating that it is a substrate and inhibits P-gp and MRP1 competitively. Furthermore, glaucine suppresses expression of ABC transporter genes. It reverses the resistance of MCF-7/ADR to adriamycin and mitoxantrone effectively. PMID:23194502
Evaluation of the grand-canonical partition function using expanded Wang-Landau simulations. III. Impact of combining rules on mixtures properties
Desgranges, Caroline; Delhommelle, Jerome
Combining rules, such as the Lorentz-Berthelot rules, are routinely used to calculate the thermodynamic properties of mixtures using molecular simulations. Here we extend the expanded Wang-Landau simulation approach to determine the impact of the combining rules on the value of the partition function of binary systems, and, in turn, on the phase coexistence and thermodynamics of these mixtures. We study various types of mixtures, ranging from systems of rare gases to biologically and technologically relevant mixtures, such as water-urea and water-carbon dioxide. Comparing the simulation results to the experimental data on mixtures of rare gases allows us to rank the performance of combining rules. We find that the widely used Lorentz-Berthelot rules exhibit the largest deviations from the experimental data, both for the bulk and at coexistence, while the Kong and Waldman-Hagler provide much better alternatives. In particular, in the case of aqueous solutions of urea, we show that the use of the Lorentz-Berthelot rules has a strong impact on the Gibbs free energy of the solute, overshooting the value predicted by the Waldman-Hagler rules by 7%. This result emphasizes the importance of the combining rule for the determination of hydration free energies using molecular simulations.
Wang-Landau density of states based study of the folding-unfolding transition in the mini-protein Trp-cage (TC5b)
NASA Astrophysics Data System (ADS)
Singh, Priya; Sarkar, Subir K.; Bandyopadhyay, Pradipta
We present the results of a high-statistics equilibrium study of the folding/unfolding transition for the 20-residue mini-protein Trp-cage (TC5b) in water. The ECEPP/3 force field is used and the interaction with water is treated by a solvent-accessible surface area method. A Wang-Landau type simulation is used to calculate the density of states and the conditional probabilities for the various values of the radius of gyration and the number of native contacts at fixed values of energy—along with a systematic check on their convergence. All thermodynamic quantities of interest are calculated from this information. The folding-unfolding transition corresponds to a peak in the temperature dependence of the computed specific heat. This is corroborated further by the structural signatures of folding in the distributions for radius of gyration and the number of native contacts as a function of temperature. The potentials of mean force are also calculated for these variables, both separately and jointly. A local free energy minimum, in addition to the global minimum, is found in a temperature range substantially below the folding temperature. The free energy at this second minimum is approximately 5 kBT higher than the value at the global minimum.

Comment on "Displacement along the Karakoram fault, NW Himalaya, estimated from LA-ICP-MS U-Pb dating of offset geologic markers" published by Shifeng Wang et al. in EPSL, 2012

Field evidence for syn-deformation migmatization and crystallization along the Karakorum fault contradicts the study of Wang et al. (2012). The ages of such magmatic rocks provide minimum ages for the onset of deformation at ∼23 Ma in North Ayilari and ∼19 Ma in Tangtse. The onset of deformation at 12 Ma in the Ayilari range inferred by Wang et al. (2012) from a muscovite Ar/Ar age is a cooling age, thus only a minimum age. The ∼60 Ma granodiorite bodies, the ophiolitic rocks and the south Kailash thrust that are correlated across the fault to provide a 52±2 km finite offset do not define reliable piercing points. Such observations as well as our previous work concur to show that the Karakorum fault initiated in the Oligo-Miocene, and has a long-term dextral slip-rate between 7.5 and 13 mm/yr, approximately twice that proposed by Wang et al. (2012).
A tale of two theorems. Comment on "Universal scaling for the dilemma strength in evolutionary games" by Z. Wang et al.
NASA Astrophysics Data System (ADS)
Tudge, Simon J.; Brede, Markus
Wang et al. [12] give an extensive review on evolutionary game theory, with a particular focus on the evolution of cooperation; an area that is of central importance to understanding many disparate biological topics [1,2,8,9]. One of the key focuses of the paper is that there are potentially two differing ways of defining two-by-two games so that they can be parameterised with only two variables. This is a highly worthwhile endeavour in that it allows one to systematically investigate and categorise all such games with much greater ease. Perhaps the key result of the paper is that the authors argue that one such parameterisation is far superior to the other, as it retains predictive power even with the additional assumption of a number of reciprocity mechanisms, such as network reciprocity. We wish to draw attention to the fact that these two parameterisations can be understood as the application of two invariance theorems in evolutionary game theory. Furthermore, we complement the authors' extensive simulations with a mathematical argument that might help explain their result in a more transparent way. We will show that one of these invariance theorems generalises to the case of an assorted population and the other does not. It may be argued that many, if not all, of the particular mechanisms of reciprocity crucially rely on the positive assortment of cooperative behaviours [3-7,10]; if one accepts this then our result acts as an argument towards why only one game parameterisation will be sufficient for models of reciprocity.

As it is well-recognized, powerful theoretical schemes for the promotion of cooperation fall into the following five categories: direct reciprocity, indirect reciprocity, kin selection, group selection, and network reciprocity, all of which got a great deal of attention and theoretical validation during the past decades [1,2]. In [3] Wang et al. briefly explain how reciprocity mechanisms work, illustrating the huge amount of theoretical work done in the area during the last decades, to finally pose some of the still unsolved puzzles that need to be solved in order to achieve a full (theoretical) understanding of the mechanisms that allow cooperative traits to survive in different scenarios.

Reply to Comments to X. Li and Y. M. Wang (2011) Comparisons of geoid models over Alaska computed with different Stokes' kernel modifications, JGS 1(2): 136-142 by L. E. Sjöberg
NASA Astrophysics Data System (ADS)
Wang, Y.
The authors thank professor Sjöberg for having interest in our paper. The main goal of the paper is to test kernel modification methods used in geoid computations. Our tests found that Vanicek/Kleusberg's and Featherstone's methods fit the GPS/leveling data the best in the relative sense at various cap sizes. At the same time, we also pointed out that their methods are unstable and the mean values change from dm to meters by just changing the cap size. By contrast, the modification of the Wong and Gore type (including the spectral combination, method of Heck and Grüninger) is stable and insensitive to the truncation degree and cap size. This feature is especially useful when we know the accuracy of the gravity field at different frequency bands. For instance, it is advisable to truncate Stokes' kernel at a degree to which the satellite model is believed to be more accurate than surface data. The method of the Wong and Goretype does this job quite well. In contrast, the low degrees of Stokes' kernel are modified by Molodensky's coefficients
Diversity of Stomoxys spp. (Diptera: Muscidae) and diurnal variations of activity of Stomoxys indicus and S. Calcitrans in a farm, in Wang Nam Khiao District, Nakhon ratchasima Province, Thailand
Keawrayup, S.; Duvallet, G.; Sukonthabhirom, S.; Chareonviriyaphap, T.
A study of species diversity of Stomoxys spp. and diurnal variations of activity of the most abundant was performed during a one year period at a local dairy cattle farm in Wang Nam Khiao District, Nakhon Ratchasima Province, Thailand. Four species of stomoxyine flies were morphologically identified, including Stomoxys indicus Picard 1908, S. calcitrans (Linnaeus 1758), S. sitiens Rondani 1873 and S. uruma Shinonaga and Kanao 1966. The most common species were S. indicus (50.2%) and S. calcitrans (49.5%). S. sitiens and S. uruma were found in small proportions (< 1%). The number of flies captured was significantly different among the three seasons with the greatest number in the rainy season (mean = 66%; df = 2, P < 0.05). The variations of diurnal activity were observed during different period of times (06:00 to 18:00) during three seasons. Both sexes of S. indicus and males of S. calcitrans showed unimodal activity pattern in cool and summer seasons. But a bimodal activity pattern was recorded in rainy season. For females S. calcitrans, a unimodal peak of activity was observed in cool season and a constant variation of activity all along the day in summer and rainy seasons, with an increase from the morning to the evening. A better understanding of stomoxyine fly behavior, especially the daily flight activity, can assist in prioritization and design of appropriate vector prevention and control strategies. PMID:22910668

New observations - with older ones reviewed - on mass migrations in millipedes based on a recent outbreak on Hachijojima (Izu Islands) of the polydesmid diplopod (Chamberlinius hualienensis, Wang 1956): Nothing appears to make much sense
MEYER-ROCHOW, Victor Benno
Mass aggregations and migrations of millipedes despite numerous attempts to find causes for their occurrences are still an enigma. They have been reported from both southern and northern hemisphere countries, from highlands and lowlands of both tropical and temperate regions and they can involve species belonging to the orders Julida and Spirobolida, Polydesmida and Glomerida. According to the main suggestions put forward in the past, mass occurrences in Diplopoda occur: (1) because of a lack of food and a population increase beyond sustainable levels; (2) for the purpose of reproduction and in order to locate suitable oviposition sites; (3) to find overwintering or aestivation sites; (4) because of habitat disruption and changes in the local environment; (5) as a consequence of weather conditions the year (or winter and spring) before. A recent outbreak (November 2014) of a mass migration of the polydesmid Chamberlinius hualienensis Wang 1956 on the Japanese Izu Island of Hachijojima 300 km to the south of Tokyo gave this author an opportunity to review the existing literature on millipede mass migrations and to carry out additional observations on the phenomenon in the field as well as the laboratory. Hitherto unreported heavy infestations with phoretic deutonymphs of the mite Histiostoma sp. as well as dense populations of internal rhabditid nematodes (Oscheius cf. necromena and an unidentified species of the genus Fictor), suggest that infestations of this kind could be necromenic and either have been a contributing factor for the mass migration or been a consequence of so many individuals occurring together at close proximity. It is concluded that mass migrations and aggregations in millipedes do not have one common cause, but represent phenomena that often are seasonally recurring events and appear identical in their outcome, but which have evolved as responses to different causes in different millipede taxa and therefore need to be examined on a case
Evaluation of the grand-canonical partition function using expanded Wang-Landau simulations. IV. Performance of many-body force fields and tight-binding schemes for the fluid phases of silicon.
Desgranges, Caroline; Delhommelle, Jerome
We extend Expanded Wang-Landau (EWL) simulations beyond classical systems and develop the EWL method for systems modeled with a tight-binding Hamiltonian. We then apply the method to determine the partition function and thus all thermodynamic properties, including the Gibbs free energy and entropy, of the fluid phases of Si. We compare the results from quantum many-body (QMB) tight binding models, which explicitly calculate the overlap between the atomic orbitals of neighboring atoms, to those obtained with classical many-body (CMB) force fields, which allow to recover the tetrahedral organization in condensed phases of Si through, e.g., a repulsive 3-body term that favors the ideal tetrahedral angle. Along the vapor-liquid coexistence, between 3000 K and 6000 K, the densities for the two coexisting phases are found to vary significantly (by 5 orders of magnitude for the vapor and by up to 25% for the liquid) and to provide a stringent test of the models. Transitions from vapor to liquid are predicted to occur for chemical potentials that are 10%-15% higher for CMB models than for QMB models, and a ranking of the force fields is provided by comparing the predictions for the vapor pressure to the experimental data. QMB models also reveal the formation of a gap in the electronic density of states of the coexisting liquid at high temperatures. Subjecting Si to a nanoscopic confinement has a dramatic effect on the phase diagram with, e.g. at 6000 K, a decrease in liquid densities by about 50% for both CMB and QMB models and an increase in vapor densities between 90% (CMB) and 170% (QMB). The results presented here provide a full picture of the impact of the strategy (CMB or QMB) chosen to model many-body effects on the thermodynamic properties of the fluid phases of Si. PMID:27036464

The author of this correspondence has recently published findings of an ecological investigation wherein herbicide use was proposed as an instrumental variable that predicts healthcare utilization among subjects with severe ADHD impairment via individual exposure to nitrous oxide (N2O) emissions. Vitamin D deficiency, a possible risk factor for autism spectrum disorders (ASD) as discussed by Wang et al., may be a homeostatic response to increasing chronic environmental N2O exposures. The author explains how deficient and insufficient states of vitamin D may promote vagal withdrawal and tolerance to increasing opioid exposures in the environment and how these characteristics are particularly relevant in neurodevelopmental disorders, like ASD and ADHD.

Azarnivand, Ali
Wang et al. (2015) employed driving force-pressure-state-impact-response (DPSIR) framework to provide a robust decision-making structure for carbon emission reduction by use of wolfberry plantation in the Jingtai oasis, China. DPSIR appropriately identified the causes of problem along with adopting the responses to the barriers associated with wolfberry plantation. However, the discusser argues that, the paper could have prepared more viable outcomes, if the authors had used causal network rather than causal chains through the DPSIR framework. Furthermore, they could have quantified the mutual relationship among the relevant factors to provide a detailed economic assessment. With this knowledge in hand, the current discussion letter suggests eDPSIR and meDPSIR to address drawbacks regarding conventional DPSIR framework. Due to proper performance of eDPSIR and meDPSIR, they are recommended as practical tools in the future environmental studies. PMID:26355261

Joint Density of States Calculation Employing Wang-Landau Algorithm
NASA Astrophysics Data System (ADS)
Kalyan, M. Suman; Bharath, R.; Sastry, V. S. S.; Murthy, K. P. N.
Joint density of states (JDoS), which depends both on energy and another variable like order parameter provides more information than the conventional density of states (DoS) which depend only on energy. Calculation of JDoS requires huge computational time. In this paper we employ two level method to calculate JDoS which requires relatively much less computational time. We demonstrate this method on a two dimensional Ising spin system, lattice spin model of double strand DNA (dsDNA) and Heisenberg ferromagnet.
VizieR Online Data Catalog: NGC 2808 AGB and RGB stars Na abundance (Wang+, 2016)
NASA Astrophysics Data System (ADS)
Wang, Y.; Primas, F.; Charbonnel, C.; van der Swaelmen, M.; Bono, G.; Chantereau, W.; Zhao, G.
The high-resolution spectra of our sample of AGB and RGB stars in the Galactic globular cluster NGC 2808 were obtained with the high-resolution multi-object spectrograph FLAMES, mounted on ESO/VLT-UT2. A combined mode was used where the brightest five objects was observed with UVES-fibre and the remaining targets with GIRAFFE/Medusa. The basic information of our sample stars are listed in Table 2, including the evolutionary phase, instrument used for observation, coordinates, photometry and barycentric radial velocity. Our Fe abundances were derived from the equivalent widths of Fe lines, while the Na abundances were determined with spectra synthesis. Both FeI and Na abundances have been corrected for the non-LTE effect. In Table 4 we show the derived stellar parameters of our sample stars, and the Na abundances are shown in Table 6.

Photometric observations of BP Peg were obtained on November 4, 2013 by using the 1.0-m reflecting telescope at Yunnan Observatories (YNOs) that is equipped with a Cassegrain-focus multicolor CCD photometer. An Andor DW436 2K CCD camera together with the wide-band, Johnson-Cousins Rc and Ic filters, attached to this Cassegrain telescope is used. To increase the photometric precision, we also observed the variable star without filters. BP Peg was also observed on December 29, 2013 by using the 85-cm telescope at the Xinglong Station of National Astronomical Observatory (NAO). The telescope is equipped with a primary-focus multi-color CCD photometer where a PI1024 BFT (Back-illuminated and Frame-Transfer) camera is used as the detector. The wide-band filter in V was used during the observations. (1 data file).

Argonne's Michael Wang talks about the GREET Model for reducing vehicle emi
Michael Wang
To fully evaluate energy and emission impacts of advanced vehicle technologies and new transportation fuels, the fuel cycle from wells to wheels and the vehicle cycle through material recovery and vehicle disposal need to be considered. Sponsored by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE), Argonne has developed a full life-cycle model called GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation). It allows researchers and analysts to evaluate various vehicle and fuel combinations on a full fuel-cycle/vehicle-cycle basis. The first version of GREET was released in 1996. Since then, Argonne has continued to update and expand the model. The most recent GREET versions are the GREET 1 2012 version for fuel-cycle analysis and GREET 2.7 version for vehicle-cycle analysis.

Wang, J.; Xie, J.-W.; Barclay, T.; Fischer, D. A.
Our sample consists of bright host stars with multi-planet transiting systems from Kepler. Out of 5779 Kepler Objects of Interest (http://exoplanetarchive.ipac.caltech.edu/), we selected all the systems with a Kepler magnitude (KP) brighter than 13.5mag and with at least two planet candidates. The sample includes 343 planet candidates (see Table3) in 138 multi-planet candidate systems (see Table2) from the Kepler mission. For these systems, we used archival data from Kepler to characterize their stellar (see Table2) and orbital properties (see Table3). We used UKIRT images to calculate brightness contrast curves and to detect stellar companions around planet candidate host stars (see Table4). (3 data files).

G.; Morgan, J. S.; Onaka, P. M.; Price, P. A.; Stubbs, C. W.; Sweeney, W.; Tonry, J. L.; Wainscoat, R. J.; Waters, C.
Data used in this study include photometry and proper motion measurements within a 5° radius around the Praesepe center (R.A.=08h40m, decl.=+19°42', J2000). Archival data were taken from the 2MASS Point Sources Catalog (2MASS; cat. II/246), PPMXL (Roeser et al. 2010, cat. I/317), and Panoramic Survey Telescope And Rapid Response (Pan-STARRS). Pan-STARRS is a wide-field (7deg2) imaging system, with a 1.8m, f/4.4 telescope, equipped with a 1.4 giga-pixel camera. The prototype (PS1), located atop Haleakala, Maui, USA, has been patrolling the entire sky north of -30° declination since mid-2010 with a combination of gP1, rP1, iP1, zP1, and yP1 bands. The PS1 filters differ slightly from those of the SDSS. The gP1 filter extends 20nm redward of gSDSS for greater sensitivity and lower systematics for photometric redshift estimates. SDSS has no corresponding y filter (Tonry et al. 2012, cat. J/ApJ/750/99). Upon the completion of its 3.5yr mission by early 2014, PS1 will provide reliable photometry and astrometry. Table1 lists the properties of the 1040 candidates. (1 data file).

DOE/GO/15075-MacDiarmid-Wang Final Technical Report
Wang, Pen-Cheng
Since Cho et al. reported up to ~8 wt% room-temperature hydrogen adsorption in HCl-treated polyaniline and polypyrrole [1], the research on the interactions between hydrogen and conducting polymers has become an area of special interest in the hydrogen economy community. However, later studies on hydrogen sorption using conducting polymers gave controversial results, which showed either much lower H2 uptake [2] or no H2 uptake at all [3]. As conducting polymers possess some unique "unconventional" and complex characteristics [4], it is highly likely that the controversial results could be attributed to the variation in material characteristics caused by "ambiguous" processing/handling procedures employed in H2 uptake studies involving conducting polymers. In order to determine whether conducting polymers can be developed into a new type of high-performance media for hydrogen storage applications, the goals of the project were to (i) confirm the brief report by Cho et al. [1] that ~8 wt% hydrogen gas storage in doped (metallic) forms of organic conducting polymers ("synthetic metals"), polyaniline and polypyrrole, can be attained, (ii) determine the optimum polymer preparative methods, chemical composition, polymer electrode potential, polymer crystallinity and morphology to give quantitative optimum conditions of hydrogen gas adsorption and desorption and (iii) investigate hydrogen storage by the many known types of organic conducting polymers in their semiconducting and, metallic forms, and in selected oxidation states.
[The influence of ZHU Gong's Huo ren shu (A Book for Savings Life)in the Southern Song Dynasty and its Influence on the discipline of Cold Pathogenic Disease].
Lu, Ming-Xin
ZHU Gong's Huo ren shu (A Book for Saving Life) is a famous work in the history of research on Treatise on Cold Damage Diseases. It has great influence on the study of cold pathogenic disease, especially that of the Song dynasty. Many authors reedited or annotated this book to inherit and developed the idea of the Huo ren shu. Thus, a lot of new books, including annotations, revisions, citations, or discussions, appeared. WANG Su's Zeng shi nan yang huo ren shu (Amplified Annotated Huorenshu), for example, is one of them. Those compiled as rhymes or knacks include XU Shu-wei's Shang han bai zheng ge (The Rhymes of Hundred Kinds of Cold Damage Disease), LI Zhi-xian's Huo ren shu kuo (Introduction to Huorenshu), QIAN Wen-li's Shang han bai wen ge (Hundred Questions on Cold Damage Disease), YANG Shi-ying's Shang han lei shu huo ren zong kuo (A General Introduction to Huorenshu, a Classified Book of Cold Damage Disease), and TANG Yin-cai's Shang han jie huo lun (Essay to Answering Suspicions on Cold Damage Disease). Those cited or inherited the book include LI Cheng's Shang han yao zhi (Gist of Cold Damage Disease), GUO Yong's Shang han bu wang lun (Supplements to Cold Damage Disease), SUN Zhi-ning's Shang han jian yao shi shuo (Ten Simple Discourses on Cold Damage Disease), and CHEN Zi-ming's Guan jian da quan liang fang (A Complete Effective Formulary with my Own Opinions). Those differentiating the essentials of the Huorenshu including CHENG Jiong's Huo ren shu bian (Differentiation for Huorenshu), and LU Zu-chang's Ni jin huo ren can tong yu yi (An Elaboration on Huorenshu to be Presented). All the above books indicate the impact of the Huorenshu, and show its influence on later ages as well. PMID:23363846
Biases in Global Reanalysis Datasets Undermine Intraseasonal Prediction Skill Xiouhua Fu1, Bin Wang, June-Yi Lee, Wanqiu Wang, and Li Gao 1International Pacific Research Center (IPRC), SOEST, University of Hawaii at Manoa
NASA Astrophysics Data System (ADS)
Fu, J. X.
Predictability of Intra-Seasonal Oscillation (ISO) relies on both initial conditions and lower boundary conditions (or atmosphere-ocean interaction). The atmospheric reanalysis datasets are commonly used as initial conditions. Here, the biases of three reanalysis datasets (NCEP_R1, _R2, and ERA_Interim) in describing ISO were revealed and the impacts of these biases as initial conditions on ISO prediction skills were assessed. A signal recovery method is proposed to improve ISO prediction. All three reanalysis datasets underestimate the intensity of the equatorial eastward-propagating ISO. When these reanalyses are used as initial conditions in the ECHAM4-UH hybrid coupled model (UH_HCM hereinafter), skillful ISO prediction reaches only about one week for both the 850-hPa zonal winds (U850) and rainfall over Southeast Asia and the global tropics. An enhanced nudging of divergence field is shown to significantly improve the initial conditions, resulting in an extension of the skillful rainfall prediction by 2-3 days and U850 prediction by 5-10 days. After recovering the ISO signals in the original reanalyses, the resultant initial conditions contain ISO strength much closer to the observed. Use of these signal-recovered reanalyses as initial conditions extends the skillful prediction of U850 and rainfall, respectively, to 23 and 18 days over Southeast Asia, and to 20 and 10 days over the global tropics. This finding underlines the urgent need to improve data assimilation systems and observations in advancement of ISO prediction by offering better initial conditions. It is also found that small-scale synoptic weather disturbances in initial conditions generally increase ISO prediction skill. The UH_HCM has better rainfall prediction than the NCEP Climate Forecast System (CFS) over Southeast Asia and both models suffer the prediction barrier over the Maritime Continent.

Gooch, Eugene
Most students are intimidated by the reputation of organic chemistry, while others see the course as nonessential to their career goals. While they usually have the ability to meet the challenge and succeed, many seek any mechanism by which they can pass the course with minimal study time. Products like Orgo Cards pander to such desires and will not be of benefit to the student with mediocre talent or poor motivation. The best students who buy this set may be bright enough to focus on those very well done mechanisms. But remember, there's nothing in Orgo Cards that isn't already in a good organic text.
The law of cooperation: Comment on "Universal scaling for the dilemma strength in evolutionary games" by Z. Wang et al.
NASA Astrophysics Data System (ADS)
Ichinose, Genki
Cooperation is a behavior that benefits others while incurring costs to the actor. Thus, natural selection favors defection (non-cooperation), which unilaterally takes the benefits without paying any costs, rather than cooperation. Despite this logical consequence, reality is the opposite: Cooperation is ubiquitous at any level from genomes to human societies. This contradiction is known as the puzzle of the evolution of cooperation. For a long time, evolutionary game theorists have used the prisoner's dilemma game (PD) and the chicken game (CH) as the standard models to solve this puzzle. For these researchers, it is recognized that a specific mechanism is needed for the evolution of cooperation [1]. Five mechanisms are proposed: kin selection, direct reciprocity, indirect reciprocity, network reciprocity, and group selection. By using the donor and recipient game (D&R), which is one of the particular forms of PD, Nowak theoretically showed that once benefit (b), cost (c), and the other one or two parameters for each mechanism are given, we (evolutionary game theorists) can immediately know whether cooperation evolves [1]. The point here is that he included those unique parameters for each mechanism into PD and then reformulated the payoff matrix. Therefore, we can use this extended PD as the first scaling parameters.
Equivalence of cooperation indexes. Comment on "Universal scaling for the dilemma strength in evolutionary games" by Z. Wang et al.
NASA Astrophysics Data System (ADS)
Martinez-Vaquero, Luis; Grujić, Jelena; Lenaerts, Tom
Symmetric 2 × 2 games where two players can select between two actions and the payoff depends on what they both choose, provide one of the simplest models to study the evolution of cooperation. The actions are usually called cooperation (C) and defection (D) and the payoffs they receive are R (reward for mutual cooperation), P (punishment for mutual defection), T (temptation to defect) and S (suckers payoff). The relative ordering of these 4 payoff values determines the type of dilemma: Prisoner's Dilemma (PD) when T > R > P > S, Snowdrift with T > R > S > P and Stag-Hunt with R > T > P > S. Within the framework of Darwinian Evolution it is well known that in the PD, where both greed (T > R) and fear (P > S) are present, the evolution of cooperation is an important conundrum [1], requiring the identification of mechanisms to overcome it.

We report calculations of energy levels and radiative rates for transitions among the lowest 116 fine-structure levels arising from the n<=5 configurations in Be-like ions with Z=10-30. The wavelengths, oscillator strengths, line strengths, and radiative rates for all possible electric dipole, magnetic dipole, electric quadrupole, and magnetic quadrupole transitions among the 116 levels have been calculated using the combined configuration interaction and many-body perturbation method. The accuracy of the results is determined through extensive comparisons with existing laboratory measurements and theoretical results. The present complete set of results should be of great help in line identification and the interpretation of spectra, as well as in the modeling and diagnostics of astrophysical and fusion plasmas.

Combined relativistic configuration interaction and many-body perturbation calculations are performed for the 359 fine-structure levels of the 2s22p3, 2s2p4, 2p5, 2s22p23l, 2s2p33l, 2p43l, and 2s22p24l configurations in N-like ions from Ar XII to Zn XXIV. Complete and consistent data sets of energies, wavelengths, radiative rates, oscillator strengths, and line strengths for all possible electric dipole, magnetic dipole, electric quadrupole, and magnetic quadrupole transitions among the 359 levels are given for each ion. The present work significantly increases the amount of accurate data for ions in the nitrogen-like sequence, and the accuracy of the energy levels is high enough to enable the identification and interpretation of observed spectra involving the n=3, 4 levels, for which experimental values are largely scarce. Meanwhile, the results should be of great help for modeling and diagnosing astrophysical and fusion plasmas. (2 data files).

[Clinical features of Wei Yuheng].
Yu, Zhong-yuan
Wei Yuheng held that the endogenous miscellaneous diseases are mostly caused by liver diseases, highly stressed the treating method of nourishing yin to generate liver. He claimed that liver deficiency is mostly caused by congenital factors, sexual strain or improper treatment. He criticized that the improper treatment by elder generations mainly was caused by their ignorance of tonifying the liver based on the saying of "no tonifying treatment for the liver". Wei Yuheng's medical theories and clinical experiences are scattered in his book Xu Mingyi Lei'an (Supplement to Classified Case Records of Celebrated Physicians). Wang Mengying collected part of his thoughts and experiences and wrote the book Liuzhou Yihua (Liuzhou Medical Talks). Although Wang Mengying's book could deduce part of the thoughts of Wei Yuheng, it didn't disclose his theories completely. It is known to all that the compound recipe Yiguan Jian is a representative formula of Wei Yuheng to tonify liver yin. Actually, it can be concluded from the analysis of Xu Mingyi Lei'an that he used Fructus Lycii (Gouqi) as a main herb to tonify liver yin in the method of nourishing yin to generate liver. Based on the idea that there are accept, restriction, generation and transformation relationship among the lung, kidney and liver yin, so he also always used Radix Glehniae (Beishashen), Radix Ophiopogonis (Maidong), Radix Rehmanniae Recens (Shengdihuang), and Radix Rehmanniae Preparata (Shudihuang) in his compound recipes. If the yin blood is insufficient, Semen Ziziphi Spinosae (Suanzaoren) should be added. In order to prepare a out way for phlegm-heat caused dy liver yin deficiency, a lubricative, Semen Trichosanthis (Gualouren) was always used and raw Semen Coicis Recens (Shengyiyiren) too. Sichuan Rhizoma Coptidis (Chuanhuanglian) can be used to clear fire-heat, and Fructus Meliae Toosendan (Chuanlianzi) for pain caused by fire-heat. PMID:17096983
Nonlinear and Nonequilibrium Spin Injection in Magnetic Tunneling Junctions

Guo, Hong
Quantitative analysis of charge and spin quantum transport in spintronic devices requires an atomistic first principles approach that can handle nonlinear and nonequilibrium transport conditions. We have developed an approach for this purpose based on real space density functional theory (DFT) carried out within the Keldysh nonequilibrium Green's function formalism (NEGF). We report theoretical analysis of nonlinear and nonequilibrium spin injection and quantum transport in Fe/MgO/Fe trilayer structures as a function of external bias voltage. Devices with well relaxed atomic structures and with FeO oxidization layers are investigated as a function of external bias voltage. We also report calculations of nonequilibrium spin injection into molecular layers and graphene. Comparisons to experimental data will be presented.

Scaling up complexity in host-pathogens interaction models. Comment on "Coupled disease-behavior dynamics on complex networks: A review" by Z. Wang et al.
NASA Astrophysics Data System (ADS)
Aguiar, Maíra
Caused by micro-organisms that are pathogenic to the host, infectious diseases have caused debilitation and premature death to large portions of the human population, leading to serious social-economic concerns. The persistence and increase in the occurrence of infectious diseases as well the emergence or resurgence of vector-borne diseases are closely related with demographic factors such as the uncontrolled urbanization and remarkable population growth, political, social and economical changes, deforestation, development of resistance to insecticides and drugs and increased human travel. In recent years, mathematical modeling became an important tool for the understanding of infectious disease epidemiology and dynamics, addressing ideas about the components of host-pathogen interactions. Acting as a possible tool to understand, predict the spread of infectious diseases these models are also used to evaluate the introduction of intervention strategies like vector control and vaccination. Many scientific papers have been published recently on these topics, and most of the models developed try to incorporate factors focusing on several different aspects of the disease (and eventually biological aspects of the vector), which can imply rich dynamic behavior even in the most basic dynamical models. As one example to be cited, there is a minimalistic dengue model that has shown rich dynamic structures, with bifurcations (Hopf, pitchfork, torus and tangent bifurcations) up to chaotic attractors in unexpected parameter regions [1,2], which was able to describe the large fluctuations observed in empirical outbreak data [3,4].
The importance of accurately modelling human interactions. Comment on "Coupled disease-behavior dynamics on complex networks: A review" by Z. Wang et al.

Rosati, Dora P.; Molina, Chai; Earn, David J. D.
Human behaviour and disease dynamics can greatly influence each other. In particular, people often engage in self-protective behaviours that affect epidemic patterns (e.g., vaccination, use of barrier precautions, isolation, etc.). Self-protective measures usually have a mitigating effect on an epidemic [16], but can in principle have negative impacts at the population level [12,15,18]. The structure of underlying social and biological contact networks can significantly influence the specific ways in which population-level effects are manifested. Using a different contact network in a disease dynamics model-keeping all else equal-can yield very different epidemic patterns. For example, it has been shown that when individuals imitate their neighbours' vaccination decisions with some probability, this can lead to herd immunity in some networks [9], yet for other networks it can preserve clusters of susceptible individuals that can drive further outbreaks of infectious disease [12].

Connecting human behavior and infectious disease spreading. Comment on "Coupled disease-behavior dynamics on complex networks: A review" by Wang et al.

Vaccination against measles is one of the great success stories of 20th century medicine. In the USA, before the introduction of the vaccine in 1963, three to four million adolescents were infected annually, around 500 died, around 5000 got serious complications (primarily encephalitis, swelling of the brain), and around 50,000 were hospitalized [7]. With the vaccine, measles virtually vanished and by 2000 it was declared extinct from the USA. This was, however, not the end of the story. There is still a small fraction of parents who do not let their children be vaccinated. The reasons vary-fear of side effects, an aversion of exposing children to something "unnatural", and a large number of other ideas. (For a non-academic account of the psychology of vaccination, we recommend Eula Biss's On Immunity[3].) The last few decades, anti-vaccination ideas have been spreading in social media and united people opposing vaccination into something of a movement [4]. In December 2014 there was a first larger outbreak (over 500 cases) of the century, centered around Disneyland (Anaheim, California) [10], and the anti-vaccination movement got much of the blame [4]. This example illustrates how ideas and opinions-that just like diseases are spreading over networks of people-can facilitate outbreaks. The reverse is, thankfully, more common-people, aware of an emerging outbreak, try to lower the chance of contagion by improving hygiene etc., which impedes the outbreak.
Taxonomic Status, Phylogenetic Affinities and Genetic Diversity of a Presumed Extinct Genus, Paraisometrum W.T. Wang (Gesneriaceae) from the Karst Regions of Southwest China

Background The karst regions in South China have an abundance of endemic plants that face high extinction risks. The Chinese Gesneriaceae endemic Paraisometrum mileense ( = Oreocharis mileensis), was presumed extinct for 100 years. After its re-discovery, the species has become one of five key plants selected by the Chinese forestry government to establish a new conservation category for plants with extremely small populations. For conservation purposes, we studied the phylogenetic and population genetic status of P. mileense at the three only known localities in Guangxi, Guizhou and Yunnan. Methodology/Principal Findings We collected 64 samples (52 species) of Oreocharis and 8 samples from three provinces of P. mileense and generated molecular phylogenies, and inferred that P. mileense represents a relatively isolated and derived taxonomic unit within Oreocharis. Phylogeographic results of 104 samples of 12 populations of P. mileense indicated that the populations in Yunnan have derived from those in Guangxi and Guizhou. Based on AFLP data, the populations were found to harbor low levels of genetic diversity (He = 0.118), with no apparent gradient across the species' range, a restricted gene flow and significant isolation-by-distance with limited genetic differentiation among the populations across the three provinces (FST = 0.207, P<0.001). The 10 populations in Yunnan were found to represent two distinct lineages residing at different altitudes and distances from villages. Conclusion/Significance The low levels of genetic diversity found in P. mileense are perhaps a consequence of severe bottlenecks in the recent past. The distribution of the genetic diversity suggests that all populations are significant for conservation. Current in situ and ex situ measures are discussed. Further conservation actions are apparently needed to fully safeguard this conservation flagship species. Our work provides a model of an integrated study for the numerous endemic species in the karst regions with extremely small populations. PMID:25250568

Since the very inception of mathematical modeling in epidemiology, scientists exploited the simplicity ingrained in the assumption of a well-mixed population. For example, perhaps the earliest susceptible-infectious-recovered (SIR) model developed by L. Reed and W.H. Frost in the 1920s [1], included the well-mixed assumption such that any two individuals in the population could meet each other. The problem was that, unlike many other simplifying assumptions used in epidemiological modeling whose validity holds in one situation or the other, well-mixed populations are almost non-existent in reality because the nature of human socio-economic interactions is, for the most part, highly heterogeneous (e.g. [2-6]).

Sánchez, Angel
The emergence and stability of cooperation has received a great deal of attention in the last two decades, and in fact the number of papers about this issue has increased in the last few years: compare the 155 references in [1] with the 314 in [2]. In spite of all this effort, the conditions allowing cooperation to be sustained are still unclear, in particular among humans, a key issue to understand our complex societies. One of the main reasons for this is that the models proposed to study cooperativeness from a theoretical viewpoint have ingredients, such as evolutionary dynamics or population structure, whose choice changes dramatically the corresponding predictions. Furthermore, apparently minor details, e.g., the presence of small mutations or different time scales in the dynamics, strongly modify the model outcomes, as discussed in detail in [1]. In this context, the review [2] deals with one of this difficulties, namely the effect of the payoff values on cooperation in a set of social dilemmas, and proposes a reparametrization that might lead to a more unified view.

The puzzle of cooperation exists widely in the realistic world, including biological, social, and engineering systems. How to solve the cooperation puzzle has received considerable attention in recent years [1]. Evolutionary game theory provides a common mathematical framework to study the problem of cooperation. In principle, these practical biological, social, or engineering systems can be described by complex game models composed of multiple autonomous individuals with mutual interactions. And generally there exists a dilemma for the evolution of cooperation in the game systems.

The application of classical game theory to biological sciences allowed researchers to successfully approach problems in theoretical and evolutionary biology in a novel manner [1]. Among those, the evolution of cooperation is the most popular application of evolutionary game theory. The evolution of cooperation is traditionally modeled through games, in particular social dilemmas. These depict situations, in which the interest of an individual is in conflict with the interest of the group, thus games offer an ideal ground to study how cooperation can emerge in the face of natural selection, where individual advantage triumphs over group benefits.

Rodrigues, Francisco A.
Epidemic modeling is fundamental to our understanding of the disease dynamics [1]. Theoretical models have allowed the development of methods for immunization and vaccination policies, being used for disease forecast and control [1-3]. Typically, disease propagation is modeled as a stochastic process in which an infectious agent is transmitted from an infected individual to a susceptible subject via the connection between them [4]. The initial models to describe the disease propagation considered homogeneous-mixing compartmental models [2], which assume that all subjects have identical probabilities of interaction. In this way, the network of contacts is a fully connected graph wherein the interaction might happen between every pair of individuals [2].

Understanding the mechanisms at the origin of cooperation is a major challenge to Darwin's natural selection theory [1]: If only the fittest individuals survive, how to explain the ubiquity of cooperation? Among many examples of altruistic behaviors, one can mention insects that coordinate their efforts for the benefit of their "queen" [2].
Screening of antinociceptive components in Corydalis yanhusuo W.T. Wang by comprehensive two-dimensional liquid chromatography/tandem mass spectrometry.
Wang, Chen; Wang, Shuowen; Fan, Guorong; Zou, Hanfa
Formalin-induced pain models were used in rats to evaluate the antinociceptive effect of the total alkaloids of Corydalis yanhusuo (TAC). The results indicated that formalin-evoked spontaneous nociceptive responses (licking behavior) could be inhibited significantly by giving (intragingival) TAC at a single dose of 150 mg/kg. Subsequently, an online comprehensive two-dimensional biochromatography method with a silica-bonded human serum albumin (HSA) column in the first dimension and a monolithic ODS column in the second was developed. The absorbed bioactive components were screened by comparing and contrasting the components detected in the plasma and striatum with those in TAC. More than 100 compounds were separated and detected in the TAC, among which 13 compounds were identified. About 40 compounds (seven compounds identified) were absorbed into the plasma with appropriate concentrations and about 20 compounds (four compounds identified) passed through the blood-brain barrier into the striatum. Of interest, four compounds (protopine, glaucine, tetrahydropalmatine, and corydaline) which were reported to possess profound antinociceptive effects exhibited high concentrations in the striatum. This may result from their synergistic effects in regulating the formalin-induced nociception. The results indicated that the comprehensive two-dimensional biochromatography method developed is capable of screening the bioactive components in Corydalis yanhusuo and providing valuable information for understanding the mechanisms by which Corydalis yanhusuo alleviates nociception.

Large-Scale Simulation of the Effects of Climate Change on Runoff Erosion Following Extreme Wildfire Events Authors: Gould, Adam, Warren, Barber, Wagenbrenner, Robichaud, Wang, Cherkauer

Across the western U.S., there is clear concern for increases in wildfire occurrence, severity, and post-fire runoff erosion due to projected climate changes. The aim of this study was to advance our capability to simulate post-fire runoff erosion at scales larger than a single hillslope to examine the relative contribution of sediment being released to larger streams and rivers in response to wildfire. We applied the Variable Capacity Infiltration-Water Erosion Prediction Project (VIC-WEPP), a newly-developed physically-based modeling framework that combines large-scale hydrology with hillslope-scale runoff erosion, over the Salmon River basin (SRB) in central Idaho. We selected the SRB for this study because of recent research that suggested that forest wildfires are likely contributing the majority of coarser sands that settle in downstream navigation channels and in reservoirs, causing adverse impacts to aquatic life, navigation, and flood storage. Using the Normalized Burn Ratio (NBR), burn intensity and severity maps show the regularity of wildfire occurrence in the SRB. These maps compare pre-fire images to next growing season images from the Landsat Thematic Mapper multispectral scanning sensor. Rather than implementing WEPP over all hillslopes within the SRB, we applied a representative hillslope approach. A monofractal scaling method downscales globally available 30 arc second digital elevation model (DEM) data to a 30 m resolution for simulations. This information determined the distribution of slope gradients within each VIC grid cell. This study applied VIC-WEPP over the 1979-2010 period and compared an ensemble of future climate simulations for the period of 2041-2070. For future scenarios, we only considered meteorological impacts on post-fire erosion and did not incorporate changes in future fire occurrence or severity. We ran scenarios for a variety of land cover and soil parameter sets, particularly those that relate to pre and post-fire characteristics, such as vegetative cover, interrill and rill erodibility factors, and saturated hydraulic conductivity. Evaluation of runoff erosion at experimental sites, observed by the U.S. Forest Service, involved using Disturbed WEPP which showed reasonable first post-fire year annual erosion predictions. We evaluated VIC-WEPP by comparing sediment observations downstream of the SRB with simulated yields for both pre and post-fire conditions. Generation of maps showing erosion over the SRB for each of the scenarios show specific areas within the SRB to be high, moderate, or low runoff-induced post-fire erosion regions. Our methodology will enable forest managers in the region to incorporate the impacts of changes in meteorological events on runoff erosion into their strategic management plans.
Timing of metamorphism of the Lansang gneiss and implications for left-lateral motion along the Mae Ping (Wang Chao) strike-slip fault, Thailand
NASA Astrophysics Data System (ADS)
Palin, R. M.; Searle, M. P.; Morley, C. K.; Charusiri, P.; Horstwood, M. S. A.; Roberts, N. M. W.
The Mae Ping fault (MPF), western Thailand, exhibits dominantly left-lateral strike-slip motion and stretches for >600 km, reportedly branching off the right-lateral Sagaing fault in Myanmar and extending southeast towards Cambodia. Previous studies have suggested that the fault assisted the large-scale extrusion of Sundaland that occurred during the Late Eocene-Early Oligocene, with a geological offset of ˜120-150 km estimated from displaced high-grade gneisses and granites of the Chiang Mai-Lincang belt. Exposures of high-grade orthogneiss in the Lansang National Park, part of this belt, locally contain strong mylonitic textures and are bounded by strike-slip ductile shear zones and brittle faults. Geochronological analysis of monazite from a sample of sheared biotite-K-feldspar orthogneiss suggests two episodes of crystallization, with core regions documenting Th-Pb ages between c. 123 and c. 114 Ma and rim regions documenting a significantly younger age range between c. 45-37 Ma. These data are interpreted to represent possible magmatic protolith emplacement for the Lansang orthogneiss during the Early Cretaceous, with a later episode of metamorphism occurring during the Eocene. Textural relationships provided by in situ analysis suggest that ductile shearing along the MPF occurred during the latter stages of, or after, this metamorphic event. In addition, monazite analyzed from an undeformed garnet-two-mica granite dyke intruding metamorphic units at Bhumipol Lake outside of the Mae Ping shear zone produced a Th-Pb age of 66.2 ± 1.6 Ma. This age is interpreted to date the timing of dyke emplacement, implying that the MPF cuts through earlier formed magmatic and high-grade metamorphic rocks. These new data, when combined with regional mapping and earlier geochronological work, show that neither metamorphism, nor regional cooling, was directly related to strike-slip motion.
Modelling real disease dynamics with behaviourally adaptive complex networks. Comment on "Coupled disease-behavior dynamics on complex networks: A review" by Z. Wang et al.

Small, Michael
Mean field compartmental models of disease transmission have been successfully applied to a host of different scenarios, and the Kermack-McKendrick equations are now a staple of mathematical biology text books. In Susceptible-Infected-Removed format these equations provide three coupled first order ordinary differential equations with a very mild nonlinearity and they are very well understood. However, underpinning these equations are two important assumptions: that the population is (a) homogeneous, and (b) well-mixed. These assumptions become closest to being true for diseases infecting a large portion of the population for which inevitable individual effects can be averaged away. Emerging infectious disease (such as, in recent times, SARS, avian influenza, swine flu and ebola) typically does not conform to this scenario. Individual contacts and peculiarities of the transmission network play a vital role in understanding the dynamics of such relatively rare infections - particularly during the early stages of an outbreak.
Unifying perspectives on cooperation under social viscosity. Comment on "Universal scaling for the dilemma strength in evolutionary games" by Z. Wang et al.

Bauch, Chris T.
How cooperation evolved in populations of self-interested agents puzzled Charles Darwin, who portrayed the paradox in The Descent of Man as such: "He who was ready to sacrifice his life, as many a savage has been, rather than betray his comrades, would often leave no offspring to inherit his noble nature" [1]. Darwin invoked group selection to explain cooperation: if groups of cooperating individuals could work together to outcompete groups of selfish individuals, cooperation could thrive. Fundamentally, this mechanism works by allowing cooperators to interact preferentially with one another: cooperators tend to interact with other co-operators whereas selfish "defectors" tend to interact with other defectors. Since cooperators cooperate and defectors defect, groups of cooperators should do better, on average.

Outbreaks of disease can trigger spontaneous behavioral response of individuals to consider prevention measures (mainly including medical cure and non-pharmaceutical intervention), which usually in turn influence the diffusion of epidemic, namely, forming the interplay between individual behaviors and epidemic dynamics. During the past decade, understanding such coupled disease-behavior dynamics in population has become a critical tool for predicting the disease evolution and designing effective prevention strategies [1-3].

Han, The Anh
"I will jump into the river to save two brothers or eight cousins": This famous quote by J.B.S. Haldane accurately anticipates the conditions under which cooperation is the favorable choice in an interaction between genetic relatives. The general condition can later be formulated as a surprisingly simple mathematical expression, known as the Hamilton's rule, stating that natural selection favors cooperation if the genetic relatedness (r) between the donor and the recipient of a cooperative act is greater than its cost (c) to benefit (b) ratio [1]: r > c / b. Motivated by Hamilton's elegant early studies, researchers have attempted to find simple and concise rules that characterize the conditions for cooperation to be selected under various social viscosity [2,3]. For example, the seminal work by M. Nowak [3] in 2006 shows that similarly simple rules can be derived that govern each of the other four popular mechanisms of cooperation-direct reciprocity, indirect reciprocity, group selection and network reciprocity-, which can be expressed via the cost-to-benefit ratio being smaller than some critical value associated with the mechanism at work (as seen, for kin interactions, the critical value is relatedness). However, these rules are restricted to the donor and recipient (D&R) paradigm. The question is thus whether it is possible to obtain simple rules even for the general case? The answer is not trivial as a general two-player game is described by four independent parameters, not just two as in the D&R game.

Radio imaging spectroscopy over wide range wavelength in dm/cm-bands will open new windows on solar flares and coronal mass ejections by tracing the radio emissions from accelerated electrons. The Chinese Spectral Radioheliograph (CSRH) with two arrays in 400MHz-2GHz /2-15GHz ranges with 64/532 frequency channels have been established in Mingantu Observing Station, Inner Mongolia of China, since 2013 and is in test observations now. CSRH is renamed as MUSER (Mingantu Ultrawide SpEctral Radioheliograph) after it's accomplishment We will introduce the progress and current status of CSRH. Some preliminary results of CSRH will be presented.On 11 Nov2014, the first burst event was registered by MUSER-I array at 400MHz-2GHz waveband. According to SGD event list there was a C-class flare peaked at 04:49UT in the disk center and the radio bursts around 04:22-04:24UT was attributed to this flare. However, MUSER-I image observation of the burst indicates that the radio burst peaked around 04:22UT was due to the eruption at the east limb of the Sun and connected to a CME appeared in that direction about 1 hour later. This demonstrate the importance of the spectroscopy observation of the solar radio burst.Acknowledgement: The CSRH team includes Wei Wang, Zhijun Chen, Fei Liu, Lihong Geng and Jian Zhang and CSRH project is supported by National Major Scientific Equipment R&D Project ZDYZ2009-3.

Cosmic rays during the unusual solar minimum of 2009
NASA Astrophysics Data System (ADS)
Gil, Agnieszka
Examine the solar activity (SA) parameters during the quite long-lasting minimum epoch 23/24 shows that their values differ substantially in comparison with those measured in previous solar minimum epochs. The Sun was extremely quiet and there were nearly no sunspots (e.g. Smith, 2011). The averaged proton density was lower during this minimum (˜ 0.70) than in the three previous minimum epochs (Jian et al., 2011). The averaged strength of the interplanetary magnetic field during the last minimum was truly low (drop of ˜ 0.36) and the solar wind dynamic pressure decrease (˜ 0.22) was noticed (McComas et al., 2008). Solar polar magnetic fields were weaker (˜ 0.40) during this minimum in comparison with the last three minimum epochs of SA (Wang et al., 2009). Kirk et al. (2009) showed that EUV polar coronal holes area was less (˜ 0.15) than at the beginning of the Solar Cycle no. 23. The solar total irradiance at 1AU was lower more than 0.2Wm (-2) than in the last minimum in 1996 (Fröhlich, 2009). Values of the solar radio flux f10.7 were smaller than for the duration of the recent four minima (Jian et al., 2011). The tilt angle of the heliospheric current sheet declined much slower during the recent minimum in comparison with the previous two. The values of galactic cosmic rays (GCR) intensity measured by neutron monitors were the highest ever recorded (e.g. Moraal and Stoker, 2010). In 2007 neutron monitors achieved values measured during the last negative polarity minimum, 1987, and continued to grow throughout the beginning of 2010. In the same time, the level of anomalous cosmic ray intensities was comparable with the 1987 minimum (Leske et al., 2013). The average amplitude of the 27-days recurrence of the GCR intensity was as high as during the previous minimum epoch 1996 (positive polarity), much higher than during minimum one Hale cycle back (Gil et al., 2012). Modzelewska and Alania (2013) showed that 27-days periodicity of the GCR intensity stable

How can we reduce phosphorus export from lowland polders? Implications from a sensitivity analysis of a coupled model.
Huang, Jiacong; Gao, Junfeng; Yan, Renhua
Phosphorus (P) export from lowland polders has caused severe water pollution. Numerical models are an important resource that help water managers control P export. This study coupled three models, i.e., Phosphorus Dynamic model for Polders (PDP), Integrated Catchments model of Phosphorus dynamics (INCA-P) and Universal Soil Loss Equation (USLE), to describe the P dynamics in polders. Based on the coupled models and a dataset collected from Polder Jian in China, sensitivity analysis were carried out to analyze the cause-effect relationships between environmental factors and P export from Polder Jian. The sensitivity analysis results showed that P export from Polder Jian were strongly affected by air temperature, precipitation and fertilization. Proper fertilization management should be a strategic priority for reducing P export from Polder Jian. This study demonstrated the success of model coupling, and its application in investigating potential strategies to support pollution control in polder systems. PMID:27148646

As is well known, outbreak of epidemics may drive the human population to take some necessary measures to protect themselves from not being infected by infective ones, these precautions in turn will also keep from the further spreading of infectious diseases among the population. Thus, to fully comprehend the epidemic spreading behavior within real-world systems, the interplay between disease dynamics and human behavioral and social dynamics needs to be considered simultaneously, such that some effective containment-measures can be successfully developed [1-3].

Modelling infectious diseases on complex networks is a significant tool to understand the transmission of epidemics in human society, and consequently it has commanded increasing attention in the community of mathematicians, physicists, epidemiologists, public health policy-makers and so on [1-4]. Human behavior responses are associated with the emergence of infectious disease, for instance, wearing masks [5], staying away from a thick crowd [6], cutting contacts with infected individuals [7] and receiving a vaccination [8]. However, infectious diseases and human behavior were often modeled as independent systems in the literature, despite the fact that in the real world they are often mutually influential on each other, and hence their coupling exerts significant impacts on disease spread [9,10].
Virus-Mediated Chemical Changes in Rice Plants Impact the Relationship between Non-Vector Planthopper Nilaparvata lugens Stål and Its Egg Parasitoid Anagrus nilaparvatae Pang et Wang

In order to clarify the impacts of southern rice black-streaked dwarf virus (SRBSDV) infection on rice plants, rice planthoppers and natural enemies, differences in nutrients and volatile secondary metabolites between infected and healthy rice plants were examined. Furthermore, the impacts of virus-mediated changes in plants on the population growth of non-vector brown planthopper (BPH), Nilaparvata lugens, and the selectivity and parasitic capability of planthopper egg parasitoid Anagrus nilaparvatae were studied. The results showed that rice plants had no significant changes in amino acid and soluble sugar contents after SRBSDV infection, and SRBSDV-infected plants had no significant effect on population growth of non-vector BPH. A. nilaparvatae preferred BPH eggs both in infected and healthy rice plants, and tended to parasitize eggs on infected plants, but it had no significant preference for infected plants or healthy plants. GC-MS analysis showed that tridecylic aldehyde occurred only in rice plants infected with SRBSDV, whereas octanal, undecane, methyl salicylate and hexadecane occurred only in healthy rice plants. However, in tests of behavioral responses to these five volatile substances using a Y-tube olfactometer, A. nilaparvatae did not show obvious selectivity between single volatile substances at different concentrations and liquid paraffin in the control group. The parasitic capability of A. nilaparvatae did not differ between SRBSDV-infected plants and healthy plant seedlings. The results suggested that SRBSDV-infected plants have no significant impacts on the non-vector planthopper and its egg parasitoid, A. nilaparvatae. PMID:25141278

The emergence and maintenance of cooperative behavior are widely observed in various realistic systems, such as cellular organisms, vertebrates, and human society [1]. Understanding the ubiquity of cooperation is a challenging problem, attracting great interest from diverse communities. The development of evolutionary game theory contributes to valuable tools for studying the origin of cooperative behavior and solving related social dilemmas [2]. Five key reciprocal mechanisms to promote the cooperation, including direct reciprocity, indirect reciprocity, network reciprocity, group selection, and kin selection, have been identified [3], inspiring much effort in exploring the effects of game dynamics and population's connectivity structure on the patterns of cooperation. Most of current works generate conclusions by focusing on specific game models or mechanisms, which imply the probable existence of some effective and universal laws.
Comment on: "Crustal strength in central Tibet determined from Holocene shoreline deflection around Siling Co" by Xuhua Shi, Eric Kirby, Kevin P. Furlong, Kai Meng, Ruth Robinson and Erchie Wang
NASA Astrophysics Data System (ADS)
England, Philip C.; Walker, Richard T.
Shi et al. (2015) analysed the distributions of elevation of palaeoshorelines around Siling Tso, central Tibet assuming a model in which surface loads are entirely supported by an elastic lid overlying an inviscid fluid. They concluded that the thickness of the elastic lid is 20-30 km and that, for the assumption of an inviscid substrate in this model to be valid, the viscosity of the crust below the elastic lid must be less than 1- 2 ×1019 Pas. Here we relax the assumption of an inviscid lower crust and show that the distribution of shoreline elevations may be explained either by a thick elastic lid or by high viscosity in the lower crust. In the limit of an inviscid lower crust, the thickness of the elastic lid must be greater than 25 to 39 km. If the elastic lid is thinner than this, then the viscosity of the crust beneath must be at least 5 ×1019 to 2 ×1020 Pas, depending on the time interval over which the lake was loaded.

Entrepreneur achievement. Liaoning province.
Zhao, R
This paper reports the successful entrepreneurial endeavors of members of a 20-person women's group in Liaoning Province, China. Jing Yuhong, a member of the Family Planning Association at Shileizi Village, Dalian City, provided the basis for their achievements by first building an entertainment/study room in her home to encourage married women to learn family planning. Once stocked with books, magazines, pamphlets, and other materials on family planning and agricultural technology, dozens of married women in the neighborhood flocked voluntarily to the room. Yuhong also set out to give these women a way to earn their own income as a means of helping then gain greater equality with their husbands and exert greater control over their personal reproductive and social lives. She gave a section of her farming land to the women's group, loaned approximately US$5200 to group members to help them generate income from small business initiatives, built a livestock shed in her garden for the group to raise marmots, and erected an awning behind her house under which mushrooms could be grown. The investment yielded $12,000 in the first year, allowing each woman to keep more than $520 in dividends. Members then soon began going to fairs in the capital and other places to learn about the outside world, and have successfully ventured out on their own to generate individual incomes. Ten out of twenty women engaged in these income-generating activities asked for and got the one-child certificate. PMID:12287775
Photoelectron Spectroscopy Study of [Ta2B6]-: a Hexagonal Bipyramdial Cluster
NASA Astrophysics Data System (ADS)

It has been a long-sought goal in cluster science to discover stable atomic clusters as building blocks for cluster-assembled nanomaterials, as exemplified by the fullerenes and their subsequent bulk syntheses.[1,2] Clusters have also been considered as models to understand bulk properties, providing a bridge between molecular and solid-state chemistry.[3] Herein we report a joint photoelectron spectroscopy and theoretical study on the [Ta2B6]- and [Ta2B6] clusters.[4] The photoelectron spectrum of [Ta2B6]- displays a simple spectral pattern and a large HOMO-LUMO gap, suggesting its high symmetry. Theoretical calculations show that both the neutral and anion are D6h pyramidal. The chemical bonding analyses for [Ta2B6] revealed the nature of the B6 and Ta interactions and uncovered strong covalent bonding between B6 and Ta. The D6h-[TaB6Ta] gaseous cluster is reminiscent of the structural pattern in the ReB6X6Re core in the [(Cp*Re)2B6H4Cl2] and the TiB6Ti motif in the newly synthesized Ti7Rh4Ir2B8 solid-state compound.[5,6] The current work provides an intrinsic link between a gaseous cluster and motifs for solid materials. Continued investigations of the transition-metal boron clusters may lead to the discovery of new structural motifs involving pure boron clusters for the design of novel boride materials.

Multifractal analysis of 2D gray soil images
NASA Astrophysics Data System (ADS)
González-Torres, Ivan; Losada, Juan Carlos; Heck, Richard; Tarquis, Ana M.
Soil structure, understood as the spatial arrangement of soil pores, is one of the key factors in soil modelling processes. Geometric properties of individual and interpretation of the morphological parameters of pores can be estimated from thin sections or 3D Computed Tomography images (Tarquis et al., 2003), but there is no satisfactory method to binarized these images and quantify the complexity of their spatial arrangement (Tarquis et al., 2008, Tarquis et al., 2009; Baveye et al., 2010). The objective of this work was to apply a multifractal technique, their singularities (α) and f(α) spectra, to quantify it without applying any threshold (Gónzalez-Torres, 2014). Intact soil samples were collected from four horizons of an Argisol, formed on the Tertiary Barreiras group of formations in Pernambuco state, Brazil (Itapirema Experimental Station). The natural vegetation of the region is tropical, coastal rainforest. From each horizon, showing different porosities and spatial arrangements, three adjacent samples were taken having a set of twelve samples. The intact soil samples were imaged using an EVS (now GE Medical. London, Canada) MS-8 MicroCT scanner with 45 μm pixel-1 resolution (256x256 pixels). Though some samples required paring to fit the 64 mm diameter imaging tubes, field orientation was maintained. References Baveye, P.C., M. Laba, W. Otten, L. Bouckaert, P. Dello, R.R. Goswami, D.

Quantitative comparisons of analogue models of brittle wedge dynamics

Schreurs, Guido
, models accommodated initial shortening by a forward- and a backward-verging thrust. Further shortening was taken up by in-sequence formation of forward-verging thrusts. In all experiments, boundary stresses created significant drag of structures along the sidewalls. We therefore compared the surface slope and the location, dip angle and spacing of thrusts in sections through the central part of the model. All models show very similar cross-sectional evolutions demonstrating reproducibility of first-order experimental observations. Nevertheless, there are significant along-strike variations of structures in map view highlighting the limits of interpretations of analogue model results. These variations may be related to the human factor, differences in model width and/or differences in laboratory temperature and especially humidity affecting the mechanical properties of the granular materials.

In order to enhance climatic and hydrologic prediction and assessment ability in the Yellow River Basin, the climatic and hydrologic modeling system is developed based on a joint international research. The system includes three sub-modeling systems, the seasonal climatic modeling system, the climate change modeling system, and the hydrologic modeling system. The seasonal climatic modeling system is composed of a regional climate model WRF3.3.1 developed by PNNL in 2011, with domain cover whole China and surrounding areas and horizontal resolution of 30 km, the Global general circulation models (GCMs) developed by China National Climate Center (NCC), providing lateral boundary conditions to WRF3.3.1, and both dynamic and statistic downscaling tools for providing detail modeling results in the Yellow River Basin. The climate change modeling system is composed of a regional climate model RegCM4.0 modified by NCC, with domain and horizontal resolution similar to WRF3.3.1, four GCMs MIROC3.2, ECHAM5, HadCM3 and NCC-CSM1.1, providing lateral boundary conditions to RegCM4.0, respectively, for comparing the nest modeling results, and also the downscaling tools. The hydrologic modeling system is composed of a large scale semi-distributed hydrologic mode VIC(Variable Infiltration Capacity) modified by PNNL, with domain cover whole Yellow River Basin and horizontal resolution of 50 km, and a distributed hydrologic mode DHSVM3.0 (Distributed Hydrology-Soil-vegetation Mode) also modified by PNNL, with domain cover the headstream of Yellow River Basin and horizontal resolution of 0.5 km. Both VIC and DHSVM3.0 are driven by the outputs of WRF3.3.1 and RegCM4.0, and provide seasonal hydrologic predictions and future hydrologic projections under IPCC AR5 climate change scenarios SRES RCP8.5 and RCP4.5. Now the simulated seasonal climatic and hydrologic results are compared and verified by recorded data sets, and VIC and DHSVM3.0 are running for the future hydrologic simulation driven by climate change modeling outputs.

In UCID-19588, Communicating between the Apple and the Wang, we described how to take Apple DOS text files and send them to the Wang, and how to return Wang files to the Apple. It is also possible to use your Apple as an Octopus terminal, and to exchange files with Octopus 7600's. Presumably, you can also talk to the Crays, or any other part of the system. This connection has another virtue. It eliminates one of the terminals in your office.
Cross-Spectral Signatures in Global Helioseismology Data of Large-Scale Flow in the Sun
NASA Astrophysics Data System (ADS)
Woodard, M. F.
Large-scale flows in the Sun's interior have been studied using a variety of helioseismic techniques, including spectral analysis of spherical harmonic time series of photospheric velocity oscillations. Detailed maps of differential rotation have been obtained from measurements of the frequencies of resonance peaks in the power spectra. Flows can also affect power spectra in subtler ways, e.g., by their influence on the widths of resonance peaks. In addition to their spectral signature, flows and other aspherical perturbations also produce cross-spectral signatures, via the mode-coupling effect of a flow. Cross power spectra of time series of coefficients in the spherical-harmonic decomposition of SOHO/MDI medium-ℓ velocity images have been computed and are being compared with theoretical predictions. The results of a preliminary comparison of observed and theoretically predicted cross spectra for differential rotation and meridional circulation will be presented. A program to systematically map large-scale solar internal flow using cross-spectral data will be described. The author acknowledges useful discussions with colleagues, especially Doug Braun, Yuhong Fan, Aaron Birch, and Jesper Schou. He is also grateful to Jesper Schou for help in acquiring MDI data products and to NASA for support under contract NAS5-3114.

Benchmarking Deep Networks for Predicting Residue-Specific Quality of Individual Protein Models in CASP11
NASA Astrophysics Data System (ADS)
Liu, Tong; Wang, Yiheng; Eickholt, Jesse; Wang, Zheng
Quality assessment of a protein model is to predict the absolute or relative quality of a protein model using computational methods before the native structure is available. Single-model methods only need one model as input and can predict the absolute residue-specific quality of an individual model. Here, we have developed four novel single-model methods (Wang_deep_1, Wang_deep_2, Wang_deep_3, and Wang_SVM) based on stacked denoising autoencoders (SdAs) and support vector machines (SVMs). We evaluated these four methods along with six other methods participating in CASP11 at the global and local levels using Pearson's correlation coefficients and ROC analysis. As for residue-specific quality assessment, our four methods achieved better performance than most of the six other CASP11 methods in distinguishing the reliably modeled residues from the unreliable measured by ROC analysis; and our SdA-based method Wang_deep_1 has achieved the highest accuracy, 0.77, compared to SVM-based methods and our ensemble of an SVM and SdAs. However, we found that Wang_deep_2 and Wang_deep_3, both based on an ensemble of multiple SdAs and an SVM, performed slightly better than Wang_deep_1 in terms of ROC analysis, indicating that integrating an SVM with deep networks works well in terms of certain measurements.

Hybrid protocol of remote implementations of quantum operations
Zhao Ningbo; Wang Anmin
We propose a protocol of remote implementations of quantum operations by hybridizing bidirectional quantum-state teleportation (BQST) [Huelga et al., Phys. Rev. A 63, 042303 (2001)] and the Wang protocol [Wang, Phys. Rev. A 74, 032317 (2006)]. The protocol is available for remote implementations of quantum operations in the restricted sets specified in the paper. We also give a proof of the protocol and point out its optimization. As an extension, this hybrid protocol can be reduced to the BQST and Wang protocols.

Reply to 'Comment II on 'Quantum secret sharing based on reusable Greenberger-Horne-Zeilinger states as secure carriers''
Karimipour, V.
In the preceding Comment [Jian-Zhong Du, Su-Juan Qin, Qiao-Yan Wen, and Fu-Chen Zhu, Phys. Rev. A 74, 016301 (2006)], it has been shown that in a quantum secret sharing protocol proposed in [S. Bagherinezhad and V. Karimipour, Phys. Rev. A 67, 044302 (2003)], one of the receivers can cheat by splitting the entanglement of the carrier and intercepting the secret, without being detected. In this reply we show that a simple modification of the protocol prevents the receivers from this kind of cheating.
Disordered XYZ Spin Chain Simulations using the Spectrum Bifurcation Renormalization Group
NASA Astrophysics Data System (ADS)
Slagle, Kevin; You, Yi-Zhuang; Xu, Cenke
We study the disordered XYZ spin chain using the recently developed Spectrum Bifurcation Renormalization Group (SBRG) numerical method. With large disorder, the phase diagram of the eigenstates consists of three many body localized (MBL) spin glass phases separated by marginal MBL critical phases. We examine the critical phases of this model by probing the entanglement entropy and Edwards-Anderson spin glass order parameter. We also show how long-range mutual information can be used to distinguish these phases (Jian, Kim, Qi 2015).

Cryptanalysis of fair quantum blind signatures
NASA Astrophysics Data System (ADS)
He, Li-Bao; Huang, Liu-Sheng; Yang, Wei; Xu, Rui
We investigate the fair quantum blind signature scheme proposed by Wang and Wen [Wang T Y and Wen Q Y 2010 Chin. Phys. B 19 060307], which uses the fundamental properties of quantum mechanics and the availability of a trusted arbitrator. However, in this paper, we find that the protocol cannot satisfy the property of non-forgeability even under the condition that the trusted arbitrator is totally credible. Moreover, a simple feasible suggestion for improving the protocol is proposed.

Utilization of the International Association for the Study of Lung Cancer and Wang's nodal map for the identification of mediastinum and hilar lymph nodes
Xia, Yang; Ma, Yun; Arias, Sixto; Lee, Hans; Wang, Ko-Pen
Background Transbronchial needle aspiration (TBNA), serving as a remarkably invaluable and minimally invasive technique, has been widely used for the diagnosis and staging of mediastinal adenopathy and masses. To date, the International Association for the Study of Lung Cancer (IASLC) and Wang's nodal map are two well-documented intrathoracic lymph node guidelines for the TBNA procedure. Method We characterized IASLC's and Wang's map, and interpreted the correlation of the two maps station by station. Results The pivotal role of IASLC map is to determine N descriptor in the tumor node metastasis (TNM) staging system of lung cancer, whilst Wang's map is employed to facilitate the localization of biopsy sites for bronchoscopists during TBNA performance. Furthermore, stations 1, 3 and 5 in Wang' map are equivalent to 4R station in IASLC' system, while stations 4 and 6 in Wang's account for IASLC station 4L as N2 stations. In addition, Wang's stations 2, 8 and 10 are correlated with station 7 in IASLC's. Wang's stations 7 and 9 are responsible for station 11R in IASLC's map. Conclusion Given their unique benefits and limitations, and the practical links between the two maps, it appears reasonable to highlight the significance of their complementary utilization upon TBNA performance and lung cancer staging.

A catalogue, based on both examined specimens and the published literature, of all the ascaridoid nematodes recorded in China is presented. A total of 95 recognised species, representing 26 genera in five families, are reported. Detailed information on the type-host, type-locality, original reference, synonyms, annotated subsequent references of taxonomic importance, other host records, site of infection, location of type-specimens and distribution are listed for each recognised species. Additional comments on the taxonomic status of some species are also given. Moreover, some nomenclatural changes are proposed: (i) Toxascaris selenarctis Wang, 1965 and T. ailuri Wu, He & Hu, 1987 are placed in synonymy with Baylisascaris transfuga (Rudolphi, 1819); (ii) Raphidascaris lophii Wang & Wu, 1991 is a secondary homonym of R. lophii (Wu, 1949) and a replacement name, R. wangi nom. nov., is proposed for the former species; (iii) Aliascaris aetoplatea Luo, 2001 is transferred to Terranova Leiper & Atkinson, 1914, as T. aetoplatea (Luo, 2001) n. comb., and should be considered a species inquirenda; (iv) Ophidascaris orientalis (Wang, 1965) is resurrected as a valid species; (v) Phocascaris longispiculum Wang & Wu, 1991 and Ophidascaris agkistrodontis Wang, 1979 are treated as incertae sedis; and (vi) Hysterothylacium sauridae Li, Xu & Zhang, 2008 is listed as a nomen nudum.

I first heard of Onsager's name from my M.S. degree thesis adviser J. S. Wang in Kunming, China. Wang had studied the theory of order-disorder transitions with R. H. Fowler in Cambridge, England in the 1930's. He told me one day in 1944-45 that Onsager had produced an exact solution of the Ising model in two dimensions. Wang was a quiet and reserved person. But that day he was evidently quite excited. I can remember still today, half a century later, the tone of admiration bordering on agitation with which he told me about Onsager's paper. I then looked up the paper [26J, but did not understand the strategic plan of Onsager's method. Onsager seemed to have a predilection for calculating commutators at every possible turn without supplying the reasons for so doing...
Information leakage in three-party simultaneous quantum secure direct communication with EPR pairs
NASA Astrophysics Data System (ADS)
Wang, Lian-Ying; Chen, Xiu-Bo; Xu, Gang; Yang, Yi-Xian
In 2007, Wang et al. [M. Y. Wang and F. L. Yan, Chin. Phys. Lett. 24 (2007) 2486] proposed a three-party simultaneous quantum secure direct communication (3P-SQSDC) scheme with EPR pairs. Recently, Chong et al. [S. K. Chong and T. Hwang, Opt. Commun. OPTICS-15438 (2010(online))] proposed an enhancement on Wang et al.'s scheme. The communications in Chong et al.'s 3P-SQSDC can be paralleled and thus their scheme has higher efficiency. However, we find that both of the schemes have the information leakage, because the legitimate parties' secret messages have a strong correlation. This kind of security loophole leads to the consequence that any eavesdropper (Eve) can directly conjecture some information about the secrets without any active attack.
Spatially correlated heterogeneous aspirations to enhance network reciprocity
NASA Astrophysics Data System (ADS)
Tanimoto, Jun; Nakata, Makoto; Hagishima, Aya; Ikegaya, Naoki
Perc & Wang demonstrated that aspiring to be the fittest under conditions of pairwise strategy updating enhances network reciprocity in structured populations playing 2×2 Prisoner's Dilemma games (Z. Wang, M. Perc, Aspiring to the fittest and promoted of cooperation in the Prisoner's Dilemma game, Physical Review E 82 (2010) 021115; M. Perc, Z. Wang, Heterogeneous aspiration promotes cooperation in the Prisoner's Dilemma game, PLOS one 5 (12) (2010) e15117). Through numerical simulations, this paper shows that network reciprocity is even greater if heterogeneous aspirations are imposed. We also suggest why heterogeneous aspiration fosters network reciprocity. It distributes strategy updating speed among agents in a manner that fortifies the initially allocated cooperators' clusters against invasion. This finding prompted us to further enhance the usual heterogeneous aspiration cases for heterogeneous network topologies. We find that a negative correlation between degree and aspiration level does extend cooperation among heterogeneously structured agents.
Phonology is necessary, but not sufficient: a rejoinder.
Paul, Peter V; Wang, Ye; Trezek, Beverly J; Luckner, John L
Paul, Wang, Trezek, and Luckner offer a rebuttal to an article by Allen, Clark, del Giudice, Koo, Lieberman, Mayberry, and Miller published in the same issue of the American Annals of the Deaf (Fall 2009) that is critical of an article by Wang, Trezek, Luckner, and Paul that was published in the Fall 2008 Annals. Major themes from the article by Wang and colleagues are reiterated, and the research and theoretical support for the qualitative-similarity hypothesis is emphasized. In addition, specific assertions made in the four sections of the article by Allen and colleagues, which are mostly overgeneralizations and misunderstandings, are addressed. Finally, concluding remarks regarding the importance of phonology are provided. PMID:20066917
Non-human lnc-DC orthologs encode Wdnm1-like protein
Dijkstra, Johannes M.; Ballingall, Keith T.
In a recent publication in Science, Wang et al. found a long noncoding RNA (lncRNA) expressed in human dendritic cells (DC), which they designated lnc-DC. Based on lentivirus-mediated RNA interference (RNAi) experiments in human and murine systems, they concluded that lnc-DC is important in differentiation of monocytes into DC. However, Wang et al. did not mention that their so-called "mouse lnc-DC ortholog" gene was already designated " Wdnm1-like" and is known to encode a small secreted protein. We found that incapacitation of the Wdnm1-like open reading frame (ORF) is very rare among mammals, with all investigated primates except for hominids having an intact ORF. The null-hypothesis by Wang et al. therefore should have been that the human lnc-DC transcript might only represent a non-functional relatively young evolutionary remnant of a protein coding locus. Whether this null-hypothesis can be rejected by the experimental data presented by Wang et al. depends in part on the possible off-target (immunogenic or otherwise) effects of their RNAi procedures, which were not exhaustive in regard to the number of analyzed RNAi sequences and control sequences. If, however, the conclusions by Wang et al. on their human model are correct, and they may be, current knowledge regarding the Wdnm1-like locus suggests an intriguing combination of different functions mediated by transcript and protein in the maturation of several cell types at some point in evolution. We feel that the article by Wang et al. tends to be misleading without the discussion presented here. PMID:25309733

Evaluation of two Vaisala RS92 radiosonde solar radiative dry bias correction algorithms
Dzambo, Andrew M.; Turner, David D.; Mlawer, Eli J.
Solar heating of the relative humidity (RH) probe on Vaisala RS92 radiosondes results in a large dry bias in the upper troposphere. Two different algorithms (Miloshevich et al., 2009, MILO hereafter; and Wang et al., 2013, WANG hereafter) have been designed to account for this solar radiative dry bias (SRDB). These corrections are markedly different with MILO adding up to 40 % more moisture to the original radiosonde profile than WANG; however, the impact of the two algorithms varies with height. The accuracy of these two algorithms is evaluated using three different approaches: a comparison of precipitable water vapor (PWV), downwellingmore » radiative closure with a surface-based microwave radiometer at a high-altitude site (5.3 km m.s.l.), and upwelling radiative closure with the space-based Atmospheric Infrared Sounder (AIRS). The PWV computed from the uncorrected and corrected RH data is compared against PWV retrieved from ground-based microwave radiometers at tropical, midlatitude, and arctic sites. Although MILO generally adds more moisture to the original radiosonde profile in the upper troposphere compared to WANG, both corrections yield similar changes to the PWV, and the corrected data agree well with the ground-based retrievals. The two closure activities – done for clear-sky scenes – use the radiative transfer models MonoRTM and LBLRTM to compute radiance from the radiosonde profiles to compare against spectral observations. Both WANG- and MILO-corrected RHs are statistically better than original RH in all cases except for the driest 30 % of cases in the downwelling experiment, where both algorithms add too much water vapor to the original profile. In the upwelling experiment, the RH correction applied by the WANG vs. MILO algorithm is statistically different above 10 km for the driest 30 % of cases and above 8 km for the moistest 30 % of cases, suggesting that the MILO correction performs better than the WANG in clear-sky scenes
On the equivalence of LIST and DIIS methods for convergence acceleration
Garza, Alejandro J.; Scuseria, Gustavo E.
Self-consistent field extrapolation methods play a pivotal role in quantum chemistry and electronic structure theory. We, here, demonstrate the mathematical equivalence between the recently proposed family of LIST methods [Wang et al., J. Chem. Phys. 134, 241103 (2011); Y. K. Chen and Y. A. Wang, J. Chem. Theory Comput. 7, 3045 (2011)] and the general form of Pulay's DIIS [Chem. Phys. Lett. 73, 393 (1980); J. Comput. Chem. 3, 556 (1982)] with specific error vectors. Our results also explain the differences in performance among the various LIST methods.

Metagenomic profiles of free-living archaea, bacteria and small eukaryotes in coastal areas of Sichang island, Thailand
Background Tha Wang and Tham Phang coasts, though situated at similar oceanographic positions on Sichang island, Chonburi province, Thailand, are different in bay geography and amount of municipal disturbances. These affect the marine ecosystems. The study used metagenomics combined with 16S and 18S rDNA pyrosequencing to identify types and distributions of archaea, bacteria, fungi and small eukaryotes of sizes ranges 0.45 and ~30 μm. Results Following the open bay geography and minimal municipal sewages, Tham Phang coast showed the cleaner water properties, described by color, salinity, pH, conductivity and percent dissolved oxygen. The 16S and 18S rDNA metagenomic profiles for Tha Wang and Tham Phang coasts revealed many differences, highlighting by low Lennon and Yue & Clayton theta similarity indices (66.03-73.03% for 16S rDNA profiles, 2.85-25.38% for 18S rDNA profiles). For 16S rDNA, the percent compositions of species belonging to Proteobacteria, Bacteroidetes, Cyanobacteria, Firmicutes, Verrucomicrobia, Gammatimonadetes, Tenericutes, Acidobacteria, Spirochaetes, Chlamydiae, Euryarchaeota, Nitrospirae, Planctomycetes, Thermotogae and Aquificae were higher or distinctly present in Tha Wang. In Tham Phang, except Actinobacteria, the fewer number of prokaryotic species existed. For 18S rDNA, fungi represented 74.745% of the species in Tha Wang, whereas only 6.728% in Tham Phang. Basidiomycota (71.157%) and Ascomycota (3.060%) were the major phyla in Tha Wang. Indeed, Tha Wang-to-Tham Phang percent composition ratios for fungi Basidiomycota and Chytridiomycota were 1264.701 and 25.422, respectively. In Tham Phang, Brachiopoda (lamp shells) and Mollusca (snails) accounted for 80.380% of the 18S rDNA species detected, and their proportions were approximately tenfold greater than those in Tha Wang. Overall, coastal Tham Phang comprised abundant animal species. Conclusions Tha Wang contained numerous archaea, bacteria and fungi, many of which could synthesize
Maximum Principle of Optimal Control of the Primitive Equations of the Ocean with Two Point Boundary State Constraint
Tachim Medjo, Theodore
We study in this article the Pontryagin's maximum principle for a class of control problems associated with the primitive equations (PEs) of the ocean with two point boundary state constraint. These optimal problems involve a two point boundary state constraint similar to that considered in Wang, Nonlinear Anal. 51, 509-536, 2002 for the three-dimensional Navier-Stokes (NS) equations. The main difference between this work and Wang, Nonlinear Anal. 51, 509-536, 2002 is that the nonlinearity in the PEs is stronger than in the three-dimensional NS systems.
Evaluation of two Vaisala RS92 radiosonde solar radiative dry bias correction algorithms
NASA Astrophysics Data System (ADS)
Dzambo, A. M.; Turner, D. D.; Mlawer, E. J.
Solar heating of the relative humidity (RH) probe on Vaisala RS92 radiosondes results in a large dry bias in the upper troposphere. Two different algorithms (Miloshevich et al., 2009, MILO hereafter; and Wang et al., 2013, WANG hereafter) have been designed to account for this solar radiative dry bias (SRDB). These corrections are markedly different with MILO adding up to 40 % more moisture to the original radiosonde profile than WANG; however, the impact of the two algorithms varies with height. The accuracy of these two algorithms is evaluated using three different approaches: a comparison of precipitable water vapor (PWV), downwelling radiative closure with a surface-based microwave radiometer at a high-altitude site (5.3 km MSL), and upwelling radiative closure with the space-based Atmospheric Infrared Sounder (AIRS). The PWV computed from the uncorrected and corrected RH data is compared against PWV retrieved from ground-based microwave radiometers at tropical, mid-latitude, and arctic sites. Although MILO generally adds more moisture to the original radiosonde profile in the upper troposphere compared to WANG, both corrections yield similar changes to the PWV, and the corrected data agree well with the ground-based retrievals. The two closure activities - done for clear-sky scenes - use the radiative transfer models MonoRTM and LBLRTM to compute radiance from the radiosonde profiles to compare against spectral observations. Both WANG- and MILO-corrected RH are statistically better than original RH in all cases except for the driest 30 % of cases in the downwelling experiment, where both algorithms add too much water vapor to the original profile. In the upwelling experiment, the RH correction applied by the WANG vs. MILO algorithm is statistically different above 10 km for the driest 30 % of cases and above 8 km for the moistest 30 % of cases, suggesting that the MILO correction performs better than the WANG in clear-sky scenes.

Response to Comment on "A histone acetylation switch regulates H2A.Z deposition by the SWR-C remodeling enzyme".
Watanabe, Shinya; Peterson, Craig L
Wang et al report a failure to reproduce our biochemical observation that the INO80C and SWR1C/SWR1/SWR-C chromatin remodeling enzymes catalyze replacement of nucleosomal H2A.Z with H2A when the substrate contains H3-K56Q. They point to technical problems with our dimer exchange assay. In response, we have recapitulated our findings using a mobility shift assay that was developed and employed by Wang and colleagues.

Complementing T-cell Function: An Inhibitory Role of the Complement System in T-cell-Mediated Antitumor Immunity.
Peng, Weiyi; McKenzie, Jodi A; Hwu, Patrick
New data from Wang and colleagues show that complement C3 suppresses the function of CD8(+) tumor-infiltrating T cells by inhibiting IL10 production, and targeting the complement receptors C3aR and C5aR enhances the antitumor activity of immune checkpoint blockade. Their results not only define a new role of complement receptors as T-cell coinhibitory receptors, but also are useful in the development of novel strategies to improve the effectiveness of cancer immunotherapy.

Functional oxide nanobelts - from materials to nanodevices
NASA Astrophysics Data System (ADS)
Lin, Zhong; Wang
Nanowire and nanotube based materials have been demonstrated as building blocks for nanocircuits, nanosystems and nano-optoelectronics. Recently, ultra-long belt-like, quasi-one-dimensional nanostructures (so called nanobelts or nanoribbons) have been successfully synthesized for semiconducting oxides of zinc, tin, indium, cadmium and gallium, by simply evaporating the desired commercial metal oxide powders at high temperatures [1]. The as-synthesized oxide nanobelts are pure, structurally uniform, single crystalline and most of them free from dislocations; they have a rectangular-like cross-section with typical widths of 30 - 300 nm, width-to-thickness ratios of 5 - 10 and lengths of up to a few millimeters. The belt-like morphology appears to be a unique and common structural characteristic for the family of semiconducting oxides with cations of different valence states and materials of distinct crystallographic structures. Using the technique demonstrated for measuring the mechanical properties of carbon nanotubes based on in-situ transmission electron microscopy [2,3], the bending modulus of the oxide nanobelts has been measured and the nanobelt is shown to be a dual mode nanoresonator for NEMS technology. Field effect transistors [4] and ultra-sensitive nano-size gas sensors [5], nanoresonators and nanocantilevers [6] have also been fabricated based on individual nanobelts. Thermal transport along the nanobelt has also been measured. Nanocantilevers based on nanobelts have been fabricated. Very recently, structurally nanobelts exhibiting piezoelectric and ferroelectric properties have been synthesized, which could be a candidate for nano-scale traducers, actuators and sensors. [1] Z.W.

Disease dynamics for the hometown of migrant workers.
Sigdel, Ram P; McCluskey, C Connell
A recent paper by L. Wang, X. Wang J. Theoret. Biol. 300:100--109 (2012) formulated and studied a delay differential equation model for disease dynamics in a region where a portion of the population leaves to work in a different region for an extended fixed period. Upon return, a fraction of the migrant workers have become infected with the disease. The global dynamics were not fully resolved in that paper, but are resolved here. We show that for all parameter values and all delays, the unique equilibrium is globally asymptotically stable, implying that the disease will eventually reach a constant positive level in the population.

Monitoring and Diagnosing Malicious Attacks with Autonomic Software
NASA Astrophysics Data System (ADS)
Souza, Vítor E. Silva; Mylopoulos, John
Monitoring and diagnosing (M&D) software based on requirement models is a problem that has recently received a lot of attention in field of Requirement Engineering. In this context, Wang et al. [1] propose a M&D framework that uses goal models to diagnose failures in software at different levels of granularity. In this paper we extend Wang's framework to monitor and diagnose malicious attacks. Our extensions include the addition of anti-goals to model attacker intentions, as well as context-based modeling of the domain within which our system operates. The extended framework has been implemented and evaluated through a series of experiments intended to test its scalability.
Information Leakage in Efficient Bidirectional Quantum Secure Direct Communication with Single Photons in Both Polarization and Spatial-Mode Degrees of Freedom
NASA Astrophysics Data System (ADS)
Zhang, Cai; Situ, Haozhen
Recently, Wang et al. presented a bidirectional quantum secure direct communication protocol with single photons in both polarization and spatial-mode degrees of freedom (Int. J. Theor. Phys. 54(10): 3443-3453, 2015). They claimed that their protocol was efficient and removed the drawback of information leakage. However, we found that the information leakage actually exists in their protocol. In this paper, we analyze Wang et al.'s protocol in detail. In addition, we propose an improvement to avoid the information leakage. The security of the improved protocol has also been discussed.
[Micro and nondestructive analysis of blue dyes from silk fabrics and decorative painting of historic building].
Zhang, Xiao-Mei; Wei, Xi-Ning; Lei, Yong; Cheng, Xiao-Lin; Zhou, Yang
Dye analysis is important to the understanding of fabric color degradation and technical development of ancient printing and dyeing. In the present study, thin layer chromatography and Raman spectroscopy were used for the analysis of blue dyes from 6 silk fabric of Tang dynasty and decorative painting of Jian Fu Gong, Forbidden City. The applicability of these two methods in the cultural heritages was also studied. The results indicate that all these blue substances are indigo; indigo was not only used as dye in ancient fabrics, but also as pigment in decorative painting of historic building, so it is used widely. Both analytic methods have advantages and disadvantages; Raman spectroscopy is nondestructive analysis; thin layer chromatography needs small amount of sample, but could give more information.

Autonomic correlates of attachment insecurity in a sample of women with eating disorders.
Dias, Pedro; Soares, Isabel; Klein, John; Cunha, João P S; Roisman, Glenn I
This study examined associations between attachment insecurity and autonomic response during the Adult Attachment Interview (AAI) in a sample of 47 women with eating disorders using a new system for the synchronous acquisition of behavioral and physiological data: the Bio Dual-channel and Representation of Attachment Multimedia System (BioDReAMS; Soares, Cunha, Zhan Jian Li, Pinho, & Neves, 1998). Consistent with the emerging literature on the psychophysiology of adult attachment, insecurity was positively correlated with electrodermal reactivity during the AAI. Furthermore, relatively secure patients showed some evidence of parasympathetic withdrawal, which can be conceptualized as evidence of more effective emotion regulation. Results suggest that, even among women with diagnosed psychopathology, security is associated with moreproductive patterns of psychophysiological response to attachment-related challenges.

[Development of external medicine and dermatology of TCM in the Republican period].
He, Zhongjun; Wang, Li
The inheritance of the theory in external medicine in the Republican period was mainly derived from Wai ke zheng zong (Orthodox Manual of External Medicine) and Yi zong jin jian (Golden Mirror of Medicine) and the sorting out of medical plasters, pills, and powders from Wai ke shi san fang (Thirteen Recipes of External Medicine). Zhang Shanlei's Yang ke gang yao (Guidelines for Ulcerations), based on the five-year experience of Zhu's family, offers new experience and ideas for syndrome differentiation; Ding Ganren's diagnosis for external medicine is exquisite with many well known formulae prescribed by himself; Monographs on leprosy and syphilis were published by famous physicians. Departments of external medicine and anal diseases, and classes on external medicine and dermatology and venereal diseases were set up in TCM schools in Guangdong and Zhejiang provinces with teaching materials compiled. All these mark the development of external medicine in modern age. PMID:26420528
Spectrum reconstruction based on the constrained optimal linear inverse methods.
Ren, Wenyi; Zhang, Chunmin; Mu, Tingkui; Dai, Haishan
The dispersion effect of birefringent material results in spectrally varying Nyquist frequency for the Fourier transform spectrometer based on birefringent prism. Correct spectral information cannot be retrieved from the observed interferogram if the dispersion effect is not appropriately compensated. Some methods, such as nonuniform fast Fourier transforms and compensation method, were proposed to reconstruct the spectrum. In this Letter, an alternative constrained spectrum reconstruction method is suggested for the stationary polarization interference imaging spectrometer (SPIIS) based on the Savart polariscope. In the theoretical model of the interferogram, the noise and the total measurement error are included, and the spectrum reconstruction is performed by using the constrained optimal linear inverse methods. From numerical simulation, it is found that the proposed method is much more effective and robust than the nonconstrained spectrum reconstruction method proposed by Jian, and provides a useful spectrum reconstruction approach for the SPIIS.

Disordered XYZ spin chain simulations using the spectrum bifurcation renormalization group
NASA Astrophysics Data System (ADS)
Slagle, Kevin; You, Yi-Zhuang; Xu, Cenke
We study the disordered XYZ spin chain using the recently developed spectrum bifurcation renormalization group [Y.-Z. You et al., Phys. Rev. B 93, 104205 (2016), 10.1103/PhysRevB.93.104205] numerical method. With strong disorder, the phase diagram consists of three many-body localized (MBL) spin-glass phases. We argue that, with sufficiently strong disorder, these spin-glass phases are separated by marginally MBL critical lines. We examine the critical lines of this model by measuring the entanglement entropy and Edwards-Anderson spin-glass order parameter, and find that the critical lines are characterized by an effective central charge c'=ln2 . Our data also suggest continuously varying critical exponents along the critical lines. We also demonstrate how long-range mutual information [introduced in C.-M. Jian et al., arXiv:1508.07006] can distinguish these phases.
Effects of standing wave states on low temperature growth of 2D Pb islands on Si(111) surfaces
NASA Astrophysics Data System (ADS)
Tsong, Tien T.
Flat-top 2D Pb islands of nanometer size with critical and magic thickness have been observed in the Pb/Si(111)-7x7 system at low temperature using scanning tunneling microscopy. The growth behavior, formation of new electronic bound states, redistribution of surface charge density, and oscillatory relaxations in the island thickness arise from quantum size effects. All these properties are perfectly correlated to each other [1]. This and other more recent results will be presented. Work supported by the NSC of ROC and Academia Sinica. [1]. W. B. Su, S. H.

The title compound, C10H12FN3S, crystallizes in the same space group (P21/c) as two polymorphic forms of 4-phenyl-1-(propan-2-ylidene)thiosemicarbazone [Jian et al. (2005). Acta Cryst. E61, o653–o654; Venkatraman et al. (2005). Acta Cryst. E61, o3914–o3916]. The arrangement of molecules relative to the twofold screw axes is similar to that in the crystal structure of the lower density polymorph. In the solid state, the molecular conformation is stabilized by an intramolecular N—H⋯N hydrogen bond. The molecules form centrosymmetric R 2 2(8) dimers in the crystal through pairs of N—H⋯S hydrogen bonds. PMID:22220027
Soybean β-Conglycinin Induces Inflammation and Oxidation and Causes Dysfunction of Intestinal Digestion and Absorption in Fish
Zhang, Jin-Xiu; Guo, Lin-Ying; Feng, Lin; Jiang, Wei-Dan; Kuang, Sheng-Yao; Liu, Yang; Hu, Kai; Jiang, Jun; Li, Shu-Hong; Tang, Ling; Zhou, Xiao-Qiu
β-conglycinin has been identified as one of the major feed allergens. However, studies of β-conglycinin on fish are scarce. This study investigated the effects of β-conglycinin on the growth, digestive and absorptive ability, inflammatory response, oxidative status and gene expression of juvenile Jian carp (Cyprinus carpio var. Jian) in vivo and their enterocytes in vitro. The results indicated that the specific growth rate (SGR), feed intake, and feed efficiency were reduced by β-conglycinin. In addition, activities of trypsin, chymotrypsin, lipase, creatine kinase, Na+,K+-ATPase and alkaline phosphatase in the intestine showed similar tendencies. The protein content of the hepatopancreas and intestines, and the weight and length of the intestines were all reduced by β-conglycinin. β-conglycinin increased lipid and protein oxidation in the detected tissues and cells. However, β-conglycinin decreased superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), glutathione peroxidase (GPx) and glutathione reductase (GR) activities and glutathione (GSH) content in the intestine and enterocytes. Similar antioxidant activity in the hepatopancreas was observed, except for GST. The expression of target of rapamycin (TOR) gene was reduced by β-conglycinin. Furthermore, mRNA levels of interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), and transforming growth factor-β (TGF-β) genes were increased by β-conglycinin. However, β-conglycinin increased CuZnSOD, MnSOD, CAT, and GPx1b gene expression. In conclusion, this study indicates that β-conglycinin induces inflammation and oxidation, and causes dysfunction of intestinal digestion and absorption in fish, and finally reduces fish growth. The results of this study provide some information to the mechanism of β-conglycinin-induced negative effects. PMID:23520488
Impact of the Three Gorges Dam on reproduction of four major Chinese carps species in the middle reaches of the Changjiang River
NASA Astrophysics Data System (ADS)
Li, Mingzheng; Duan, Zhonghua; Gao, Xin; Cao, Wenxuan; Liu, Huanzhang
Silver carp ( Hypophthalmichthys molitrix), bighead carp ( Aristichthys nobilis), grass carp ( Ctenopharyngodon idella), and black carp ( Mylopharyngodon piceus) are the four major Chinese carps and are commercially important aquaculture species in China. Reproduction of these carp has declined since the construction of the Three Gorges Dam (TGD) due to an altered water flow and thermal regime in the Changjiang (Yangtze) River. However, details of the changes in reproduction of the four species are not well understood. To assess the impact of the TGD on reproduction of the four carp, we investigated their eggs and larvae at Yidu City, which is 80 km below the TGD, during 2005-2012. We examined diff erences in larval abundance of the four species in the Jianli section (350 km downstream of the TGD) before (1997-2002) and after (2003-2012) construction of the TGD. Based on these observations, the first spawning date of the four species was delayed a mean of about 25 days after the dam was constructed. Mean egg abundance in the Yidu section of the river was 249 million and mean larval abundance was 464 million, which were significant decreases since the 1980s. Moreover, larval abundance in the Jianli section after the dam was constructed was significantly lower than that before construction (ANCOVA, P<0.05). The observed larval abundance accounted for only 24.66% of the predicted value in 2003 when the dam was first inundated. The present spawning grounds between the TGD and Yidu section of the river are very similar to those described in the 1980s, and some spawning grounds exist upstream of the TGD. Large free-flowing stretches upstream of the TGD and the creation of artificially flooded downstream reaches are needed to stimulate spawning and eff ectively conserve these four major Chinese carps species.

Efficient and Anonymous Authentication Scheme for Wireless Body Area Networks.
Wu, Libing; Zhang, Yubo; Li, Li; Shen, Jian
As a significant part of the Internet of Things (IoT), Wireless Body Area Network (WBAN) has attract much attention in this years. In WBANs, sensors placed in or around the human body collect the sensitive data of the body and transmit it through an open wireless channel in which the messages may be intercepted, modified, etc. Recently, Wang et al. presented a new anonymous authentication scheme for WBANs and claimed that their scheme can solve the security problems in the previous schemes. Unfortunately, we demonstrate that their scheme cannot withstand impersonation attack. Either an adversary or a malicious legal client could impersonate another legal client to the application provider. In this paper, we give the detailed weakness analysis of Wang et al.'s scheme at first. Then we present a novel anonymous authentication scheme for WBANs and prove that it's secure under a random oracle model. At last, we demonstrate that our presented anonymous authentication scheme for WBANs is more suitable for practical application than Wang et al.'s scheme due to better security and performance. Compared with Wang et al.'s scheme, the computation cost of our scheme in WBANs has reduced by about 31.58%. PMID:27091755

Solar source regions for 3He-rich solar energetic particle events identified using imaging radio, optical, and energetic particle observations. ApJ 648, 1247, 2006]. Some results are obtained: first, 2 events are associated with wide (≈100°) CMEs (hereafter wide CME events), another 4 events are associated with narrow (⩽40°) CMEs (hereafter narrow CME events); second, the coronal magnetic field configuration of narrow CME events appear more simple than that of the wide CME events; third, the photospheric magnetic field evolutions of all these events show new emergence of fluxes, while one case also shows magnetic flux cancellation; fourth, the EUV jets usually occurred very close to the footpoint of the magnetic field loop, while meter type III bursts occurred near or at the top of the loop and higher than EUV jets. Furthermore, the heights of type III bursts are estimated from the result of the coronal magnetic field extrapolations.

Preservation of Subsurface Sulfates with mid-to-high degree of hydration in Equatorial regions on Mars
NASA Astrophysics Data System (ADS)
Wang, A.; Feldman, W. C.; Mellon, M. T.; Zheng, M.
We report a major development based upon the results from two sets of systematic laboratory experiments on the fundamental properties of hydrous Mg- and Fe3+-sulfates and upon an extrapolation from the thermal model of a two-layer regolith (Mellon et al., 2004). We built a quantitative relationship between the cycles of Mars obliquity and hydration degree of subsurface Mg-sulfate (Wang et al., 2012a), which is supported by two field observations, one on Mars and one on Earth. From laboratory experiments (Kong et al., 2011a, 2011b; Ling and Wang 2011; Wang et al., 2006, 2009, 2011, 2012b), we learned that (1) at low temperature (T), sulfates with a high degree of hydration (epsomite and ferricopiapite) have enlarged stability fields toward low relative humidity (RH); (2) hydrous Fe3+-sulfates have greater thermal stability than hydrous Mg-sulfates; (3) both Mg- and Fe3+-sulfates are capable of maintaining high RH in a closed environment and adsorbing an H2O film at their grain surfaces; (4) more importantly, their dehydration processes follow first order kinetics, i.e., much slower than water ice sublimation (that follows zero order kinetics). Using the activation energy (Ea) of epsomite dehydration, derived experimentally at Mars relevant atmospheric pressure (P) and partial water pressure (PH2O), we estimated the half-life (t1/2) of epsomite dehydration within a model-predicted T range of subsurface sulfate layer at the Mars equator (the warmest spot on Mars, to make a conservative estimation). We found that subsurface hydrous sulfates formed there during past high obliquity periods (obliquity >45°, before 5.4 million years ago, Laskar et al., 2004) have a high probability to maintain mid-to-high degrees of hydration even until the present epoch. This prediction based on experiments is consistent with an observation made by Spirit rover at Gusev on Mars (Arvidson et al., 2008; Johnson et al., 2007; Wang et al., 2008; Wang and Ling 2011), and also consistent with
Estimation of four land surface essential climate variables (albedo, LAI/FAPAR, and Fcover) from VIIRS data
NASA Astrophysics Data System (ADS)
Liang, Shunlin
As the successor of MODIS, the Visible Infrared Imaging Radiometer Suite (VIIRS) from the Suomi National Polar-orbiting Partnership (S-NPP) and future Joint Polar Satellite System (JPSS) brings us into a new era of global daily Earth observations. VIIRS was designed to improve upon the capabilities of the operational AVHRR and provide observation continuity with MODIS. This presentation will describe the progress in estimating four Essential Climate Variables (ECV): shortwave albedo (Wang, et al., 2013; Zhou, et al., 2016), leaf area index (LAI) (Xiao et al., 2016), fraction of absorbed photosynthetically active radiation (FAPAR) (Xiao et al., 2016), and fractional vegetation coverage (Fcover) (Li, et al., 2016) from VIIRS data. The algorithms have been peer reviewed, and shortwave albedo has been operationally produced by NOAA and accessible to the scientific community. Li, Y., K. Jia, S. Liang, Z. Xiao, X. Wang, L.

Semiconducting and piezoelectric nanoarchitectures of ZnO
NASA Astrophysics Data System (ADS)
Wang, Zhong Lin
ZnO is a semiconducting and piezoelectric material. The structure of ZnO can be described as a number of alternating planes composed of tetrahedrally coordinated O^2- and Zn^2+ ions, stacked alternatively along the c-axis. The oppositely charged ions produce positively charged (0001)-Zn and negatively charged (000-1)-O polar surfaces, resulting in a normal dipole moment and spontaneous polarization along the c-axis. We have synthesized a series of novel nanostructures of ZnO utilizing the effect from the polar surface [1-4]e. The piezoelectric coefficient of a piezoelectric nanobelt has been found to be almost tripled compared to the value of the bulk [5], clearly indicating the exciting applications of piezoelectric ZnO nanobelts for nano-scale electromechanical coupled sensors, transducers, switches and resonators. This presentation will focus on the growth mechanisms and potential applications of piezoelectric nanobelts, nanorings and nanosprings. [1] Z.W. Pan, Z.R. Dai and Z.L. Wang, Science, 209 (2001) 1947.

Survival Analysis using Bivariate Archimedean Copulas
NASA Astrophysics Data System (ADS)
Chandra, Krishnendu
In this dissertation we solve the nonidentifiability problem of Archimedean copula models based on dependent censored data (see [Wang, 2012]). We give a set of identifiability conditions for a special class of bivariate frailty models. Our simulation results show that our proposed model is identifiable under our proposed conditions. We use EM algorithm to estimate unknown parameters and the proposed estimation approach can be applied to fit dependent censored data when the dependence is of research interest. The marginal survival functions can be estimated using the copula-graphic estimator (see [Zheng and Klein, 1995] and [Rivest and Wells, 2001]) or the estimator proposed by [Wang, 2014]. We also propose two model selection procedures for Archimedean copula models, one for uncensored data and the other one for right censored bivariate data. Our simulation results are similar to that of [Wang and Wells, 2000] and suggest that both procedures work quite well. The idea of our proposed model selection procedure originates from the model selection procedure for Archimedean copula models proposed by [Wang and Wells, 2000] for right censored bivariate data using the L2 norm corresponding to the Kendall distribution function. A suitable bootstrap procedure is yet to be suggested for our method. We further propose a new parameter estimator and a simple goodness-of-fit test for Archimedean copula models when the bivariate data is under fixed left truncation. Our simulation results suggest that our procedure needs to be improved so that it can be more powerful, reliable and efficient. In our strategy, to obtain estimates for the unknown parameters, we heavily exploit the concept of truncated tau (a measure of association established by [Manatunga and Oakes, 1996] for left truncated data). The idea of our goodness of fit test originates from the goodness-of-fit test for Archimedean copula models proposed by [Wang, 2010] for right censored bivariate data.
New developments on the homogenization of Canadian daily temperature data
NASA Astrophysics Data System (ADS)
Vincent, Lucie A.; Wang, Xiaolan L.
Long-term and homogenized surface air temperature datasets had been prepared for the analysis of climate trends in Canada (Vincent and Gullett 1999). Non-climatic steps due to instruments relocation/changes and changes in observing procedures were identified in the annual mean of the daily maximum and minimum temperatures using a technique based on regression models (Vincent 1998). Monthly adjustments were derived from the regression models and daily adjustments were obtained from an interpolation procedure using the monthly adjustments (Vincent et al. 2002). Recently, new statistical tests have been developed to improve the power of detecting changepoints in climatological data time series. The penalized maximal t (PMT) test (Wang et al. 2007) and the penalized maximal F (PMF) test (Wang 2008b) were developed to take into account the position of each changepoint in order to minimize the effect of unequal and small sample size. A software package RHtestsV3 (Wang and Feng 2009) has also been developed to implement these tests to homogenize climate data series. A recursive procedure was developed to estimate the annual cycle, linear trend, and lag-1 autocorrelation of the base series in tandem, so that the effect of lag-1 autocorrelation is accounted for in the tests. A Quantile Matching (QM) algorithm (Wang 2009) was also developed for adjusting Gaussian daily data so that the empirical distributions of all segments of the detrended series match each other. The RHtestsV3 package was used to prepare a second generation of homogenized temperatures in Canada. Both the PMT test and the PMF test were applied to detect shifts in monthly mean temperature series. Reference series was used in conducting a PMT test. Whenever possible, the main causes of the shifts were retrieved through historical evidence such as the station inspection reports. Finally, the QM algorithm was used to adjust the daily temperature series for the artificial shifts identified from the respective
New View of Distant Galaxy Reveals Furious Star Formation
NASA Astrophysics Data System (ADS)
A furious rate of star formation discovered in a distant galaxy shows that galaxies in the early Universe developed either much faster or in a different way from what astronomers have thought. "This galaxy is forming stars at an incredible rate," said Wei-Hao Wang, an astronomer at the National Radio Astronomy Observatory (NRAO) in Socorro, New Mexico. The galaxy, Wang said, is forming the equivalent of 4,000 Suns a year. This is a thousand times more violent than our own Milky Way Galaxy. Location of Distant Galaxy Visible-light, left (from HST) and Infrared, right, (from Spitzer) Images: Circles indicate location of GOODS 850-5. CREDIT: Wang et al., STScI, Spitzer, NASA, NRAO/AUI/NSF Click on image for high-resolution file (1 MB) The galaxy, called GOODS 850-5, is 12 billion light-years from Earth, and thus is seen as it was only about 1.5 billion years after the Big Bang. Wang and his colleagues observed it using the Smithsonian Astrophysical Observatory's Submillimeter Array (SMA) on Mauna Kea in Hawaii. Young stars in the galaxy were enshrouded in dust that was heated by the stars and radiated infrared light strongly. Because of the galaxy's great distance from Earth, the infrared light waves have been stretched out to submillimeter-length radio waves, which are seen by the SMA. The waves were stretched or "redshifted," as astronomers say, by the ongoing expansion of the Universe. "This evidence for prolific star formation is hidden by the dust from visible-light telescopes," Wang explained. The dust, in turn, was formed from heavy elements that had to be built up in the cores of earlier stars. This indicates, Wang said, that significant numbers of stars already had formed, then spewed those heavy elements into interstellar space through supernova explosions and stellar winds. "Seeing the radiation from this heated dust revealed star formation we could have found in no other way," Wang said. Similar dusty galaxies in the early Universe may contain most of the
Mapping high-resolution incident photosynthetically active radiation over land surfaces from MODIS and GOES satellite data
NASA Astrophysics Data System (ADS)
Liang, S.; Wang, K.; Wang, D.; Townshend, J.; Running, S.; Tsay, S.
Incident photosynthetically active radiation (PAR) is a key variable required by almost all terrestrial ecosystem models. Many radiation efficiency models are linearly related canopy productivity to the absorbed PAR. Unfortunately, the current incident PAR products estimated from remotely sensed data or calculated by radiation models at spatial and temporal resolutions are not sufficient for carbon cycle modeling and various applications. In this study, we aim to develop incident PAR products at one kilometer scale from multiple satellite sensors, such as Moderate Resolution Imaging Spectrometer (MODIS) and Geostationary Operational Environmental Satellite (GOES) sensor. We first developed a look-up table approach to estimate instantanerous incident PAR product from MODIS (Liang et al., 2006). The temporal observations of each pixel are used to estimate land surface reflectance and look-up tables of both aerosol and cloud are searched, based on the top-of-atmosphere reflectance and surface reflectance for determining incident PAR. The incident PAR product includes both the direct and diffuse components. The calculation of a daily integrated PAR using two different methods has also been developed (Wang, et al., 2008a). The similar algorithm has been further extended to GOES data (Wang, et al., 2008b, Zheng, et al., 2008). Extensive validation activities are conducted to evaluate the algorithms and products using the ground measurements from FLUXNET and other networks. They are also compared with other satellite products. The results indicate that our approaches can produce reasonable PAR product at 1km resolution. We have generated 1km incident PAR products over North America for several years, which are freely available to the science community. Liang, S., T. Zheng, R. Liu, H. Fang, S. C. Tsay, S.

Effects of comprehensive therapy based on traditional Chinese medicine patterns in stable chronic obstructive pulmonary disease: a four-center, open-label, randomized, controlled study
Background Traditional Chinese medicine (TCM) has been used to treat chronic obstructive pulmonary disease (COPD) for many years. This study aimed to evaluate the efficacy and safety of the comprehensive therapy based on the three common TCM patterns in stable COPD patients. Methods A four-center, open-label randomized controlled method was conducted. A total of 352 patients were divided into the trial group (n = 176, treated with conventional Western medicine and Bu-Fei Jian-Pi granules, Bu-Fei Yi-Shen granules, and Yi-Qi Zi-Shen granules based on the TCM patterns respectively) and the control group (n = 176, treated with conventional Western medicine). The frequency and duration of acute exacerbation, lung function, clinical symptoms, 6-minute walking distance (6MWD), dyspnea scale and quality of life were observed during a 6-month treatment period and at a further 12-month follow-up. Results A total of 306 patients completed the study fully. The full analysis set (FAS) population was 350 and the per-protocol analysis set (PPS) population was 306. After the 6-month treatment and 12-month follow-up, there were significant differences between the trial and control group in the following: frequency of acute exacerbation (FAS: P = 0.000; PPS: P = 0.000); duration of acute exacerbation (FAS: P = 0.000; PPS: P = 0.001); FEV1 (FAS: P = 0.007; PPS: P = 0.008); symptoms (FAS: P = 0.001; PPS: P = 0.001); 6MWD (FAS: P = 0.045; PPS: P = 0.042); dyspnea scale (FAS: P = 0.002; PPS: P = 0.004); and physical domain (FAS: P = 0.000; PPS: P = 0.000), psychological domain (FAS: P = 0.008; PPS: P = 0.011), social domain (FAS: P = 0.001; PPS: P = 0.000) and environment domain (FAS: P = 0.015; PPS: P = 0.009) of the WHOQOL-BREF questionnaire. There were no differences between the trial and control group in FVC, FEV1% and adverse events. Conclusions Based on the TCM patterns, Bu-Fei Jian-Pi granules, Bu-Fei Yi-Shen granules and Yi-Qi Zi-Shen granules have beneficial effects on measured
Intraosseous approach to vascular access in adult resuscitation.
Fenwick, Rob
Establishing vascular access is vital to maximise resuscitation in critically ill children and adults (LaRocco and Wang 2003), and failure can result in delays in life-saving treatment (Nutbeam and Daniels 2010). The traditional intravenous access method can be difficult to achieve in patients with circulatory collapse (LaRocco and Wang 2003) and failure rates in emergency situations vary between 10 and 40 per cent (Lewis 1986). Other routes, such as endotracheal and intramuscular, do not provide controlled and reliable administration rates (Leidel et al 2009). This article focuses on the increased use of intraosseous (IO) access in adult resuscitation. The IO route is described and the indications and contraindications considered. Common insertion sites and devices of IO access are discussed. PMID:20662405

Recent work by Wang et.al. footnote Q. Wang et.al., Science 266, 422 (1994) reports rapid coherent photoisomerization in rhodopsin. The bathorhodopsin photoproduct appears in 200 fs and exhibits torsional oscillations which remain synchronized with the initial photoexcitation. We report transient absorption experiments which suggest that the fraction of excited rhodopsin molecules which does not isomerize in this fashion (approximately 1/3) remains in an electronically excited state, probably the twisted state described by Birge and Hubbard,footnote R. R. Birge and L. M. Hubbard, J. Am. Chem. Soc. 102, 2195 (1980) for ~ 3 ps and then reforms rhodopsin. This picture explains the long bleaching recovery time for rhodopsin and the controversial spectral dynamics which are observed in the red.
Estimating frame bulk and shear moduli of two double porosity layers by ultrasound transmission.
Bai, Ruonan; Tinel, Alain; Alem, Abdellah; Franklin, Hervé; Wang, Huaqing
The acoustic plane wave transmission by water saturated double porosity media is investigated. Two samples of double porosity media assumed to obey Berryman and Wang (BW) extension (Berryman and Wang, 1995, 2000) of Biot's theory in the low frequency regime are under consideration: ROBU® (pure binder-free borosilicate glass 3.3 manufactured to form the individual grains) and Tobermorite 11Å (the individual porous cement grains show irregular shapes). The de facto gap existing between theoretical and experimental data can be minimized by modifying adequately two of the parameters estimated from triaxial tests: the frame bulk and shear moduli. The frequency dependent imaginary parts that follow necessary from the minimization are in relation with the energy losses due to contact relaxation and friction between grains. PMID:27209582
Antiresonance induced spin-polarized current generation
NASA Astrophysics Data System (ADS)
Yin, Sun; Min, Wen-Jing; Gao, Kun; Xie, Shi-Jie; Liu, De-Sheng
According to the one-dimensional antiresonance effect (Wang X R, Wang Y and Sun Z Z 2003 Phys. Rev. B 65 193402), we propose a possible spin-polarized current generation device. Our proposed model consists of one chain and an impurity coupling to the chain. The energy level of the impurity can be occupied by an electron with a specific spin, and the electron with such a spin is blocked because of the antiresonance effect. Based on this phenomenon our model can generate the spin-polarized current flowing through the chain due to different polarization rates. On the other hand, the device can also be used to measure the generated spin accumulation. Our model is feasible with today's technology.
Logical computation using algorithmic self-assembly of DNA triple-crossover molecules
NASA Astrophysics Data System (ADS)
Mao, Chengde; LaBean, Thomas H.; Reif, John H.; Seeman, Nadrian C.
Recent work has demonstrated the self-assembly of designed periodic two-dimensional arrays composed of DNA tiles, in which the intermolecular contacts are directed by `sticky' ends. In a mathematical context, aperiodic mosaics may be formed by the self-assembly of `Wang' tiles, a process that emulates the operation of a Turing machine. Macroscopic self-assembly has been used to perform computations; there is also a logical equivalence between DNA sticky ends and Wang tile edges. This suggests that the self-assembly of DNA-based tiles could be used to perform DNA-based computation. Algorithmic aperiodic self-assembly requires greater fidelity than periodic self-assembly, because correct tiles must compete with partially correct tiles. Here we report a one-dimensional algorithmic self-assembly of DNA triple-crossover molecules that can be used to execute four steps of a logical (cumulative XOR) operation on a string of binary bits.

Improving Network Transport Efficiency by Edge Rewiring
NASA Astrophysics Data System (ADS)
Jiang, Zhong-Yuan; Liang, Man-Gui; Guo, Dong-Chao
Considering the heterogeneous structure of scale-free networks causing low traffic capacity of network, we propose to improve the network transport efficiency by rewiring a fraction of edges for the network. In this paper, six edge rewiring strategies are discussed and extensive simulations on Barabási-Albert (BA) scale-free networks confirm the effectiveness of these strategies. From another perspective, rewiring edges for scale-free networks directly reuse the removed edges under some edge-removal strategies [Z. Liu, M. B. Hu, R. Jiang, W. X. Wang and Q. S. Wu, Phys. Rev. E76 (2007) 037101; G. Q. Zhang, D. Wang and G. J. Li, Phys. Rev. E76 (2007) 017101], and can significantly enhance the traffic capacity of the network at the expense of increasing a little average path length. After the edge rewiring process, the network structure becomes significantly homogeneous. This work is helpful for network design and network performance optimization.
Artificial phosphorylation sites modulate the activity of a voltage-gated potassium channel
NASA Astrophysics Data System (ADS)
Ariyaratne, Amila; Zocchi, Giovanni
The KvAP potassium channel is representative of a family of voltage-gated ion channels where the membrane potential is sensed by a transmembrane helix containing several positively charged arginines. Previous work by Wang and Zocchi [A. Wang and G. Zocchi, PLoS ONE 6, e18598 (2011), 10.1371/journal.pone.0018598] showed how a negatively charged polyelectrolyte attached in proximity to the voltage sensing element can bias the opening probability of the channel. Here we introduce three phosphorylation sites at the same location and show that the response curve of the channel shifts by about 20 mV upon phosphorylation, while other characteristics such as the single-channel conductance are unaffected. In summary, we construct an artificial phosphorylation site which confers allosteric regulation to the channel.
Antiferromagnetic Ising Model in Hierarchical Networks
NASA Astrophysics Data System (ADS)
Cheng, Xiang; Boettcher, Stefan
The Ising antiferromagnet is a convenient model of glassy dynamics. It can introduce geometric frustrations and may give rise to a spin glass phase and glassy relaxation at low temperatures [ 1 ] . We apply the antiferromagnetic Ising model to 3 hierarchical networks which share features of both small world networks and regular lattices. Their recursive and fixed structures make them suitable for exact renormalization group analysis as well as numerical simulations. We first explore the dynamical behaviors using simulated annealing and discover an extremely slow relaxation at low temperatures. Then we employ the Wang-Landau algorithm to investigate the energy landscape and the corresponding equilibrium behaviors for different system sizes. Besides the Monte Carlo methods, renormalization group [ 2 ] is used to study the equilibrium properties in the thermodynamic limit and to compare with the results from simulated annealing and Wang-Landau sampling.

Are we hammering square pegs into round holes? An investigation of the meta-analyses of reading research with students who are d/Deaf or hard of hearing and students who are hearing.
Wang, Ye; Williams, Cheri
In a qualitative meta-analysis, the researchers systematically reviewed qualitative and quantitative meta-analyses on reading research with PK-12 students published after the 2000 National Reading Panel (NRP) report. Eleven qualitative and 39 quantitative meta-analyses were reviewed examining reading research with typically developing hearing students, special education hearing students (including English Language Learners), and d/Deaf or hard of hearing (d/Dhh) students. Generally, the meta-analysis yielded findings similar to and corroborative of the NRP's. Contradictory results (e.g., regarding the role of rhyme awareness in reading outcomes) most often resulted from differing definitions of interventions and their measurements. The analysis provided evidence of several instructional approaches that support reading development. On the basis of the qualitative similarity hypothesis (Paul, 2010, 2012; Paul & Lee, 2010; Paul & Wang, 2012; Paul, Wang, & Williams, 2013), the researchers argue that these instructional strategies also should effectively support d/Dhh children's reading development.

On 2-D Boussinesq equations for MHD convection with stratification effects
NASA Astrophysics Data System (ADS)
Bian, Dongfen; Gui, Guilong
This paper is concerned with the two-dimensional magnetohydrodynamics-Boussinesq system with the temperature-dependent viscosity, thermal diffusivity and electrical conductivity. The first progress on this topic was made independently by Chae and Hou-Li [8,26] where the Boussinesq system with partial constant viscosity is obtained. Recently, Wang-Zhang [45] considered the temperature-dependent viscosity and thermal diffusivity, and Li-Xu [16] generalized the Wang-Zhang's result to the inviscid case with temperature-dependent thermal diffusivity. In this paper, we include the stratification and magnetic effects and consider the full system, in the framework of low regularity. We prove that, without any smallness assumption on the initial data, the full system is globally well-posed. Moreover, by applying the uniformly bounded generalized Oseen operator, time decay estimate of the solution is obtained.
Binarization of Gray-Scaled Digital Images Via Fuzzy Reasoning
NASA Technical Reports Server (NTRS)
Dominquez, Jesus A.; Klinko, Steve; Voska, Ned (Technical Monitor)
A new fast-computational technique based on fuzzy entropy measure has been developed to find an optimal binary image threshold. In this method, the image pixel membership functions are dependent on the threshold value and reflect the distribution of pixel values in two classes; thus, this technique minimizes the classification error. This new method is compared with two of the best-known threshold selection techniques, Otsu and Huang-Wang. The performance of the proposed method supersedes the performance of Huang-Wang and Otsu methods when the image consists of textured background and poor printing quality. The three methods perform well but yield different binarization approaches if the background and foreground of the image have well-separated gray-level ranges.
Micromagnetic simulations of demagnetization curves for single-phase nanocrystalline PrFeB magnet
NASA Astrophysics Data System (ADS)
Wang, X. P.; Zhao, S. F.; Han, X. F.
The Gauss-Seidel projection method developed in [E. Weinan, X.P. Wang, SIAM J. Numer. Anal. 38 (2000) 1647-1665 and X.P. Wang, C.J. Garcia-Cervera, E. Weinan, J. Comp. Phys. 171 (2001) 357] is used to calculate the demagnetization curves for the single-phase nanocrystalline PrFeB magnet. It is observed that magnetic reversal for PrFeB magnet starts near the grain boundary where the angle between the external magnetic field and easy direction of the magnet can be as large as 90[ring operator]. We also calculated the demagnetization curves, coercivity [mu]0Hc and remanence Jr for different temperatures. The numerical results are consistent with the experimental observations.

A new genus Evemphyron Alonso-Zarazaga, Lv & Wang, gen. n., belonging to Attelabidae Rhynchitinae, is described. Its single species, Evemphyron sinense Alonso-Zarazaga, Lv & Wang, sp. n., was reared from larvae found inside seed pods of the legume Callerya dielsiana (Fabaceae, Millettieae) in Sichuan Province (China). The species is figured and placed in the Deporaini because of the presence of minute labial palpi, the strongly crescentic apex of the postmentum, and the apodemes of male IX sternite and female VIII sternite curved sinistro-anterially near their cephalic end. It shows 3-segmented labial palpi and male sex patches on the procoxae, characters that suggest a basal position in the tribe. PMID:27408602

We report spectroscopic classification by OzDES of a supernova discovered by the Dark Energy Survey (ATel #4668). The spectrum (370-885nm) was obtained with the AAOmega Spectrograph (Saunders et al. 2004, SPIE, 5492, 389) and the 2dF fibre positioner at the Anglo-Australian Telescope (AAT). Object classification was performed using superfit (Howell and Wang, 2002, BAAS, 34, 1256), the details of which are reported in the table below.

Microenvironmental InterFereNce of metabolism regulates chemosensitivity.
Akkari, Leila; Joyce, Johanna A
The tumor microenvironment is recognized as a critical regulator of cancer progression, and multiple roles are also emerging for the microenvironment in modulating response to therapeutic intervention. A recent study by Wang and colleagues identified IFN-γ as a central effector of CD8 T cell-mediated regulation of glutathione and cysteine metabolism in fibroblasts, which consequently abrogates stromal-induced resistance through modulation of cisplatin intracellular content in ovarian cancer cells.

Catlett, Timothy S; Gomez, Timothy M
Local protein synthesis directs growth cone turning of nascent axons, but mechanisms governing this process within compact, largely autonomous microenvironments remain poorly understood. In this issue, Wang et al. (2016. J. Cell Biol http://dx.doi.org/10.1083/jcb.201510107) demonstrate that the calcineurin regulator Down syndrome critical region 1 protein modulates both basal neurite outgrowth and growth cone turning.

Transmembrane channel-like (TMC) proteins have been implicated in hair cell mechanotransduction, Drosophila proprioception, and sodium sensing in the nematode C. elegans. In this issue of Neuron, Wang et al. (2016) report that C. elegans TMC-1 mediates nociceptor responses to high pH, not sodium, allowing the nematode to avoid strongly alkaline environments in which most animals cannot survive.

Boronyl Mimics Gold: a Photoelectron Spectroscopy Study
NASA Astrophysics Data System (ADS)
Jian, Tian; Lopez, Gary; Wang, Lai-Sheng
Previous studies have found that gold atom and boronyl bear similarities in bonding in many gas phase clusters. B10(BO), B12(BO), B3(BO)n (n=1, 2) were found to possess similar bonding and structures to B10Au, B12Au, B3Aun (n=1, 2), respectively. During the recent photoelectron spectroscopy experiments, the spectra of BiBO- and BiAu- clusters are found to exhibit similar patterns, hinting that they possess similar geometric structures. While BiAu- is a linear molecule, BiBO- is also linear. The similarity in bonding between BiBO- and BiAu- is owing to the fact that Au and BO are monovalent σ ligands. The electron affinities are measured to be 1.79±0.04eV for BiBO- and 1.36±0.02eV for BiAu-. The current results provide new examples for the BO/Au isolobal analogy and enrich the chemistry of boronyl and gold. H.-J. Zhai, C.-Q. Miao, S.-D. Li, L.-S. Wang, J. Phys. Chem.

How Bilayer Graphene Got a Bandgap
Wang, Feng
Graphene is the two-dimensional crystalline form of carbon, whose extraordinary electron mobility and other unique features hold great promise for nanoscale electronics and photonics. But theres a catch: graphene has no bandgap. Now Feng Wang and his colleagues at Berkeley Lab and UC Berkeley have engineered a bandgap in bilayer graphene that can be precisely controlled from 0 to 250 milli-electron volts, which is the energy of infrared radiation.
Comment on 'Nonlinear gyrokinetic theory with polarization drift' [Phys. Plasmas 17, 082304 (2010)
Leerink, S.; Parra, F. I.; Heikkinen, J. A.
In this comment, we show that by using the discrete particle distribution function the changes of the phase-space volume of gyrocenter coordinates due to the fluctuating ExB velocity do not explicitly appear in the Poisson equation and the [Sosenko et al., Phys. Scr. 64, 264 (2001)] result is recovered. It is demonstrated that there is no contradiction between the work presented by Sosenko et al. and the work presented by [Wang et al., Phys. Plasmas 17, 082304 (2010)].
An inhomogeneous T-Q equation for the open XXX chain with general boundary terms: completeness and arbitrary spin
NASA Astrophysics Data System (ADS)
Nepomechie, Rafael I.
An inhomogeneous T-Q equation has recently been proposed by Cao, Yang, Shi and Wang for the open spin-1/2 XXX chain with general (nondiagonal) boundary terms. We argue that a simplified version of this equation describes all the eigenvalues of the transfer matrix of this model. We also propose a generating function for the inhomogeneous T-Q equations of arbitrary spin.
Gold Nanocups: Colloidal Gold Nanocups with Orientation-Dependent Plasmonic Properties (Adv. Mater. 30/2016).
Jiang, Ruibin; Qin, Feng; Liu, Yejing; Ling, Xing Yi; Guo, Jun; Tang, Minghua; Cheng, Si; Wang, Jianfang
On page 6322, J. F. Wang and co-workers report a wet-chemistry method for the preparation of colloidal Au nanocups and their plasmonic properties. The Au nanocups are prepared through single-vertex-initiated Au deposition on PbS nano-octahedrons and subsequent selective dissolution of PbS. Owing to the orientation-dependent coupling strengths, the obtained Au nanocups display orientation-dependent plasmonic properties and Raman enhancements when deposited on substrates. PMID:27493069

The association between LEPR Q223R polymorphisms and breast cancer risk.
Wang, Yadong; Yang, Haiyan; Gao, Huiyan; Wang, Haiyu
Recently, we have read with great interest the article entitled "The association between polymorphisms in the leptin receptor (LEPR) gene and risk of breast cancer: a systematic review and pooled analysis" published online by Wang et al. (Breast Cancer Res Treat 136:231-239, 2012). This article suggests that the A allele of LEPR gene rs1137101 variant was low-penetrant risk factor for developing breast cancer. The result is encouraging. Nevertheless, several key issues are worth noticing. PMID:25863476
Response to Comment on "Crystal structures of translocator protein (TSPO) and mutant mimic of a human polymorphism".
Li, Fei; Liu, Jian; Zheng, Yi; Garavito, R Michael; Ferguson-Miller, Shelagh
Wang comments that the diffraction data for the structure of the A139T mutant of translocator protein TSPO from Rhodobacter sphaeroides should be used to 1.65 instead of 1.8 angstroms and that the density interpreted as porphyrin and monoolein is better fitted as polyethylene glycol. Although different practices of data processing exist, in this case they do not substantially influence the final map. Additional data are presented supporting the fit of a porphyrin and monooleins.

On page 5837, L. Yang, B. Wang, and co-workers describe a metal-organic framework (MOF) templating method to synthesize copper azide uniformly anchored in a 3D interconnected carbon matrix and evenly spaced by the electron-conductive joints. This strategy sheds light on the preparation of powerful yet safe primary explosives and fulfills the need for controllable explosive systems. PMID:27442967

Microparticles: Facile and High-Throughput Synthesis of Functional Microparticles with Quick Response Codes (Small 24/2016).
Ramirez, Lisa Marie S; He, Muhan; Mailloux, Shay; George, Justin; Wang, Jun
Microparticles carrying quick response (QR) barcodes are fabricated by J. Wang and co-workers on page 3259, using a massive coding of dissociated elements (MiCODE) technology. Each microparticle can bear a special custom-designed QR code that enables encryption or tagging with unlimited multiplexity, and the QR code can be easily read by cellphone applications. The utility of MiCODE particles in multiplexed DNA detection and microtagging for anti-counterfeiting is explored. PMID:27306741
Science communication. Comment on "Quantifying long-term scientific impact".
Wang, Jian; Mei, Yajun; Hicks, Diana
Wang et al. (Reports, 4 October 2013, p. 127) claimed high prediction power for their model of citation dynamics. We replicate their analysis but find discouraging results: 14.75% papers are estimated with unreasonably large μ (>5) and λ (>10) and correspondingly enormous prediction errors. The prediction power is even worse than simply using short-term citations to approximate long-term citations. PMID:25013055
Bridging the knowledge gap: from microbiome composition to function.
Faith, Jeremiah J
Despite the wealth of metagenomic sequencing data, the functions of most bacterial genes from the mammalian microbiota have remained poorly understood. In their recent study (Yaung et al 2015), Wang, Gerber, and colleagues present a platform which allows functional mining of bacterial genomes for genes that contribute to fitness in vivo and holds great potential for forward engineering microbes with enhanced colonization abilities in the microbiota.

Zhang, Jin; Wang, Chengyuan; Adhikari, Sondipon
A large scattering of effective atomic charge distribution was found in the literature for hexagonal boron nitride nanostructures (BNNSs). In our paper (Zhang J, Wang C Y and Sondipon A 2013 J. Phys. D: Appl. Phys. 46 235303) '±3e' was chosen as a rough approximation for the effective atomic charge in BNNSs as it gave the piezoelectric coefficient of BNNSs close to the values in the literature.

In this study, quantum simulations promise to be one of the primary applications of quantum computers, should one be constructed. This article briefly summarizes the history of quantum simulation in light of the recent result of Wang and co-workers, demonstrating calculation of the ground and excited states for a HeH+ molecule, and concludes with a discussion of why this and other recent progress in the field suggest that quantum simulations of quantum chemistry have a bright future.
The effect of elementary reactions on solitary waves in dusty plasmas
Tahraoui, A.; Annou, R.
The conditions of existence of solitons have been determined by Wang et al.[Phys. Lett. A 339, 96 (2005)], in negative ions containing dusty plasmas where Boltzmannian ions and electrons are assumed. The study is revisited taking into account actual elementary reactions in plasma conditions, viz., particles attachment by grains as well as neutrals and electron impact ionization of neutrals. Dust charge variation is self-consistently introduced leading to the Boltzmannian approximation relaxation.
Comment on "Optimum absorption and aperture parameters for realistic coupled volume spaces determined from computational analysis and subjective testing results" [J. Acoust. Soc. Am. 127, 223-232 (2010)].
Xiang, Ning; Robinson, Philip; Botts, Jonathan
A recent paper [D. T. Bradley and L. M. Wang, J. Acoust. Soc. Am. 127, 223-232 (2010)] has reported inconsistencies between the results of two different approaches for characterizing non-exponential decays in coupled-volume systems. This letter aims to expose the origin of these inconsistencies, which are due to a limitation in the methodology utilized for the analysis presented in the paper referenced above. PMID:21110551

GEOMORPHOLOGY. Comment on "Tectonic control of Yarlung Tsangpo Gorge revealed by a buried canyon in Southern Tibet".
Zeitler, Peter K; Koons, Peter O; Hallet, Bernard; Meltzer, Anne S
Wang et al. (Reports, 21 November, 2014, p. 978) describe a buried canyon upstream of the Yarlung Tsangpo Gorge and argue that rapid erosion of the gorge was merely a passive response to rapid uplift at ~2.5 million years ago (Ma). We view these data as an expected consequence emerging from feedbacks between erosion and crustal rheology active well before 2.5 Ma. PMID:26293946
Dynamic Transitions of Generalized Burgers Equation
NASA Astrophysics Data System (ADS)
Li, Limei; Ong, Kiah Wah
In this article, we study the dynamic transition for the one dimensional generalized Burgers equation with periodic boundary condition. The types of transition are dictated by the sign of an explicitly given parameter b, which is derived using the dynamic transition theory developed by Ma and Wang (Phase transition dynamics. Springer, New York, 2014). The rigorous result demonstrates clearly the types of dynamics transition in terms of length scale l, dispersive parameter δ and viscosity ν.

Algorithmic Self-Assembly of DNA: Theoretical Motivations and 2D Assembly Experiments.
Winfree, E
Abstract Biology makes things far smaller and more complex than anything produced by human engineering. The biotechnology revolution has for the first time given us the tools necessary to consider engineering on the molecular level. Research in DNA computation, launched by Len Adleman, has opened the door for experimental study of programmable biochemical reactions. Here we focus on a single biochemical mechanism, the self-assembly of DNA structures, that is theoretically sufficient for Turing-universal computation. The theory combines Hao Wang's purely mathematical Tiling Problem with the branched DNA constructions of Ned Seeman. In the context of mathematical logic, Wang showed how jigsaw-shaped tiles can be designed to simulate the operation of any Turing Machine. For a biochemical implementation, we will need molecular Wang tiles. DNA molecular structures and intermolecular interactions are particularly amenable to design and are sufficient for the creation of complex molecular objects. The structure of individual molecules can be designed by maximizing desired and minimizing undesired Watson-Crick complementarity. Intermolecular interactions are programmed by the design of sticky ends that determine which molecules associate, and how. The theory has been demonstrated experimentally using a system of synthetic DNA double-crossover molecules that self-assemble into two-dimensional crystals that have been visualized by atomic force microscopy. This experimental system provides an excellent platform for exploring the relationship between computation and molecular self-assembly, and thus represents a first step toward the ability to program molecular reactions and molecular structures.

On static Poincaré-Einstein metrics
NASA Astrophysics Data System (ADS)
Galloway, Gregory J.; Woolgar, Eric
The classification of solutions of the static vacuum Einstein equations, on a given closed manifold or an asymptotically flat one, is a long-standing and much-studied problem. Solutions are characterized by a complete Riemannian n-manifold ( M, g) and a positive function N, called the lapse. We study this problem on Asymptotically Poincaré-Einstein n-manifolds, n ≥ 3, when the conformal boundary-at-infinity is either a round sphere, a flat torus or smooth quotient thereof, or a compact hyperbolic manifold. Such manifolds have well-defined Wang mass, and are time-symmetric slices of static, vacuum, asymptotically anti-de Sitter spacetimes. By integrating a mildly generalized form of an identity used by Lindblom, Shen, Wang, and others, we give a mass formula for such manifolds. There are no solutions with positive mass. In consequence, we observe that either the lapse is trivial and ( M, g) is Poincaré-Einstein or the Wang mass is negative, as in the case of time symmetric slices of the AdS soliton. As an application, we use the mass formula to compute the renormalized volume of the warped product ( X, γ) ≃ ( M 3 , g) × N 2 ( S 1 , dt 2).
Process simulation for a new conceptual design of LNG terminal coupling NGL recovery and LNG re-gasification for maximum energy savings
NASA Astrophysics Data System (ADS)
Muqeet, Mohammed A.
With the high demands of shale gas and promising development of LNG terminals, a lot of research has focused towards the process development for effective recovery of C2+ hydrocarbons (NGL). Shale gas requires a large amount of cold energy to cool down and recover the NGL; and the LNG re-gasification process requires a lot of heat energy to evaporate for NGL recovery. Thus, coupling the shale gas NGL recovery process and LNG re-gasification process, for utilizing the cold energy from LNG re-gasification process to assist NGL recovery from shale gas has significant economic benefits on both energy saving and high value product recovery. Wang et al. developed new conceptual design of such coupled process in 2013 and later Wang and Xu developed an optimal design considering uncertainties in 2014. This work deals with process simulation of both these designs and the feasibility of the process is verified. A steady state model is developed based on the plant design proposed by Wang et al. using Aspen plusRTM and then a dynamic model of the process is developed using Aspen dynamicsRTM. An effective control strategy is developed and the flexibility of the dynamic model is examined by giving disturbances in the shale gas feed. A comparison is made between the two proposed design and the prospects of the design for real plant scenario is discussed.
Optimal Stopping with Information Constraint
Lempa, Jukka
We study the optimal stopping problem proposed by Dupuis and Wang (Adv. Appl. Probab. 34:141-157, 2002). In this maximization problem of the expected present value of the exercise payoff, the underlying dynamics follow a linear diffusion. The decision maker is not allowed to stop at any time she chooses but rather on the jump times of an independent Poisson process. Dupuis and Wang (Adv. Appl. Probab. 34:141-157, 2002), solve this problem in the case where the underlying is a geometric Brownian motion and the payoff function is of American call option type. In the current study, we propose a mild set of conditions (covering the setup of Dupuis and Wang in Adv. Appl. Probab. 34:141-157, 2002) on both the underlying and the payoff and build and use a Markovian apparatus based on the Bellman principle of optimality to solve the problem under these conditions. We also discuss the interpretation of this model as optimal timing of an irreversible investment decision under an exogenous information constraint.

Adam, Allan G.; Konder, Ricarda M.; Nickerson, Nicole M.; Linton, Colan; Tokaryk, D. W.
In the last few years, the Cheung group in Hong Kong and the Steimle group in Arizona have successfully studied several ruthenium containing diatomic molecules, RuX (X =C, O, N, B, using the laser-ablation molecular jet technique. Based on this success, the UNB spectroscopy group decided to try and find the optical signatures of other RuX molecules. Using CH_3OH and PH_3 as reactant gases, the RuH and RuP diatomic molecules have been detected in surveys of the 420 - 675 nm spectral region. RuD has also been made using fully deuterated methanol as a reactant. Dispersed fluorescence experiments have been performed to determine ground state vibrational frequencies and the presence of any low-lying electronic states. Rotationally resolved spectra for these molecules have also been taken and the analysis is proceeding. The most recent results will be presented. F.

An Eight-Degree-of-Freedom, Time-Dependent Quantum Dynamics Study for the H₂+C₂H Reaction on a New Modified potential Energy Surface
Wang, Dunyou; Huo, Winifred M.
An eight dimensional time-dependent quantum dynamics wavepacket approach is performed for the study of the H₂+C₂H ! H + C₂H₂ reaction system on a new modified potential energy surface (PES) [Chem. Phys. Lett. 409, 249 (2005)]. This new potential energy surface is obtained by modifying Wang and Bowman's old PES [ J. Chem. Phys. 101, 8646 (1994)] based on the new ab initio calculation. This new modified PES has a much lower transition state barrier height at 2.29 kcal/mol than Wang and Bowman's old PES at 4.3 kcal/mol. This study shows the reactivity for this diatom-triatom reaction system is enchanced by vibrational excitations of H₂; whereas, the vibrational excitations of C₂H only have a small effect on the reactivity. Furthermore, the bending excitations of C₂H, comparing to the ground state reaction probability, hinder the reactivity. The comparison of the rate constant between this calculation and experimental results agree with each other very well. This comparison indicates that the new modified PES corrects the large barrier height problem in Wang and Bowman's old PES.

Spatial Asian Monsoon variability at MIS 6.2 inferred from oxygen isotope records of stalagmites from Yangkou Cave, Chongqing, China
NASA Astrophysics Data System (ADS)
Huang, L.; Li, T.; Yang, X.; Shen, C.
Using the oxygen isotope records of stalagmites collected from different caves in China, Asian Monsoon (AM) variation over past 380 ka has been reconstructed (e.g. Wang et al., 2001, Science, 294, 2345-2348; Yuan et al., 2004, Science, 304, 575-578; Wang et al., 2008, Nature, 451, 1090-1093; Cheng et al., 2009, Science, 326, 248-252; Zhao et al., 2010, EPSL, 298, 191-198). Chinese cave δ18O records show that summer AM intensity primarily follows Northern Hemisphere summer insolation on orbital timescales. However, an unusual stalagmite δ18O-inferred weakest summer AM at the marine isotope stage (MIS) 6.2 (129-136 ka) is recorded in Sanbao Cave (Hubei province; 31°40'N, 110°26'E) (Wang et al., 2008, Nature, 451, 1090-1093). To clarify that this weakest summer AM during the penultimate deglaciation in Hubei province is site-specific or dominant in the entire mainland, we have collected stalagmite samples with deposition time intervals of interest from Yangkou Cave (Chongqing city; 29°2'N, 107°11'E) located about 400 km southwest to Sanbao Cave. Using MC-ICP-MS techniques on these stalagmites with high uranium levels of 1-20 ppm, we can refine the durations and intensities of the summer AM events during the entire MIS 6 and also further understand the spatial variability and possible mechanism for the weakest summer AM at the MIS 6.2.
To "bee" or not to be-on some ornamental shrimp from Guangdong Province, Southern China and Hong Kong SAR, with descriptions of three new species.
Klotz, Werner; Von Rintelen, Thomas
Several atyid specimens were collected from hill streams in Guangdong Province, Southern China and Hong Kong during fieldtrips between 2004 and 2013. Some of these species, most of them also sold as ornamental pet shrimp in the international aquarium trade, proved to be new to science by morphological observation and analysis of mtDNA sequences. Three new species, Caridina logemanni n. sp., Caridina mariae n. sp. and Caridina conghuensis n. sp., all of them members of the so called Caridina serrata species group (Cai & Ng 1999) are described in detail below. Caridina tumida Wang, Liang & Li, 2008 is synonymised with Caridina venusta Wang, Liang & Li, 2008. Caridina meridionalis Wang, Liang & Li, 2008 is moved to the genus Paracaridina Liang, Guo & Tang, 1999 and synonymised with Paracaridina zijinica Liang, 2002. New records for Caridina trifasciata Yam & Cai, 2003 and Caridina serrata Stimpson, 1860 are recorded. All species are compared to their morphologically closest congeners and the phylogenetic relationships between atyid shrimps from Southern China are shown. PMID:25544138
Water use efficiency and integrated water resource management for river basin
NASA Astrophysics Data System (ADS)
Deng, Xiangzheng; Singh, R. B.; Liu, Junguo; Güneralp, Burak
Water use efficiency and management have attracted increasing attention as water has become scare to challenge the world's sustainable development. Water use efficiency is correlated to the land use and cover changes (LUCC), population distribution, industrial structure, economic development, climate changes, and environmental governance. These factors significantly alter water productivity for water balance through the changes in natural environment and socio-economic system (Wang et al., 2015b). Consequently, dynamics of water inefficiency lower the social welfare of water allocation (Wang et al., 2015b), and induce water management alternation interactively and financially (Wang et al., 2015a). This triggers on actual water price changes through both natural resource and socioeconomic system (Zhou et al., 2015). Therefore, it is very important to figure out a mechanism of water allocation in the course of LUCC (Jin et al., 2015) at a global perspective (Zhao et al., 2015), climate and economic changes of ecosystem service at various spatial and temporal scales (Li et al., 2015).
Anagrus turpanicus sp. n. (Hymenoptera: Mymaridae) from China, an egg parasitoid of Arboridia kakogowana (Hemiptera: Cicadellidae).
Hu, Hong-Ying; Triapitsyn, Serguei V
A new Palaearctic species of Anagrus Haliday (Hymenoptera: Mymaridae), A. turpanicus Triapitsyn & Hu sp. n., is described and illustrated from Xinjiang Uyghur Autonomous Region of China. It was reared from parasitized eggs of the leafhopper Arboridia kakogowana (Matsumura) (Hemiptera: Cicadellidae) (Fig. 10) on cultivated table grapes from Turpan, which had been previously misidentified there as Erythroneura apicalis (Nawa) (e.g., Wang et al. 2004, 2011; Luan et al. 2006). This leafhopper has been an important economic pest in Turpan area since 1998, causing serious damage to the cultivated grapevines (Wang et al. 2004; Luan et al. 2006). Wang et al. (2011) reported that the mite Leptus sp. (Erythraeidae) and several unidentified spider species were the main natural enemies of Erythroneura apicalis in and around Turpan. This is the first record of A. kakogowana from China; it was not included in the key to the Chinese species of the genus Arboridia Zachvatkin by Song & Li (2015). Arboridia kakogowana is native to the eastern Palaearctic region (Japan, Korea, and Far East of Russia), and has been recently recorded as an invasive pest of cultivated grapes in southern Russia (Gnezdilov et al. 2008).

Seventh Harmonic Co-Generation by Cyclotron Resonance Acceleration
NASA Astrophysics Data System (ADS)
Wang, Changbiao; Hirshfield, J. L.; Ganguly, Achintya K.
The TE_72 mode in cylindrical waveguide has group velocity nearly equal to that of the TE_11 mode if the operating frequency of TE_72 is seven times of that of TE_11.(C. Wang, J. L. Hirshfield, and A. K. Ganguly, Phys. Rev. Lett. 77), 3819 (1996). This allows coherent radiation to be generated at the seventh harmonic while the TE_11 mode interacts with an electron beam via cyclotron autoresonance.(C. Wang and J. L. Hirshfield, Phys. Rev. E 51), 2456 (1995); M. A. LaPointe, R. B. Yoder, C. Wang, A. K. Ganguly, and J. L. Hirshfield, Phys. Rev. Lett. 76, 2718 (1996). For a 300 kV, 30 A warm beam pumped by 20 MW rf power at 2.856 GHz, simulations indicate that careful choice of the magnetic field profile and suppression of TE_11 mode after it is completely depleted can increase the seventh harmonic output up to 10 MW at 20 GHz. It is furthermore shown that injection can also benefit co-generation, both increasing harmonic output up to 16 MW and improving spent beam quality, which is helpful to beam energy recovery for efficiency enhancement.

Tunable rainbow trapped in a self-similar liquid crystal waveguide

Hu, Qing; Wang, Si-Hui; Xu, Di-Hu; Zhou, Yu; Peng, Ru-Wen; Wang, Mu
We have investigated the optical propagation through a self-similar dielectric waveguide, where a hollow core is surrounded by a coaxial Thue-Morse multilayer. It is found that due to the self-similar furcation feature in the photonic band structure, the transmission multibands are achieved. And different frequency ranges of the transmission modes can be selectively guided and spatially confined along the waveguide. Consequently, a rainbow can be trapped in the waveguide. Then by infiltrating liquid crystal into the cladding layers, the transmission modes and rainbow trapping can be tuned by altering the temperature. And transverse electric (TE) and transverse magnetic (TM) polarizations present different propagating features. The attenuation and energy density distributions of different modes in the waveguide are also discussed. The finding can be applied to designing miniaturized compact photonic devices, such as a spectroscopy on a chip, color-sorters on a chip, and photon sorters for spectral imaging.

Cellulose as Sustainable Materials for Separation Membranes
NASA Astrophysics Data System (ADS)
Chu, Benjamin
Polysaccharides, while complex, form one of the most abundant sustainable resources on earth. We want to take advantage of fundamental advances in materials understanding across length and time scales to investigate the interrelationships between structure, morphology, processing, properties, performance, and cost to meet the specific challenges arising from separation membranes for water purification. Non-woven fiber mats have unique properties, such as interconnected pores, a very large surface-to-volume ratio, and a high capacity for surface modifications. The breakthrough concept of combining fibrous mats composed of different fiber diameters for fabricating scaffolds as a unique platform for water purification is presented. Further, we take advantage of recent advances in chemical modifications, structural studies using synchrotron X-rays, and physical scale-up transformations to drastically improve filtration membrane development. Support of this work by the NSF, ONR, NIH and Stony Brook Univ. is gratefully acknowledged. The Chu/Hsiao group on water purification includes Profs. B.S.Hsiao and C.Burger, Drs.

Atmospheric temperature changes by volcanic eruptions: GPS radio occultation observations in the 2010 Icelandic and 2011 Chilean cases
NASA Astrophysics Data System (ADS)
Okazaki, Ikuya; Heki, Kosuke
Volcanic plumes modify atmospheric temperatures. Wang et al. (2009) reported localized temperature changes associated with the Mt Chaiten eruption in May 2008 using the deviation of GPS radio occultation temperature data from the NCEP global forecast system model. On 14 April 2010, a large scale eruption started under the glacier Eyjafjallajökull in Southern Iceland, and Puyehue-Cordón Caulle (Puyehue), in Chile, started eruption on 4 June, 2011. Here we study instantaneous and localized temperature changes with these two eruptions following the method of Wang et al. (2009). Post-eruption negative temperature anomalies at the 250 hPa plane were clearly observed in the Eyjafjallajökull eruption. In the Puyehue eruption, however, such anomalies were not so clear due possibly to insufficient accuracy of the forecast model. By comparing the temperature profiles in the downwind areas of the two eruptions, we found that significant temperature decreases occurred at ~ 10.5 and ~ 11.5 km altitude in the Eyjafjallajökull and the Puyehue cases, respectively. These results generally agree with Wang et al. (2009), but post-eruption temperature changes seem to be influenced by additional factors, e.g. volcanic explosivity and local climatology.

The fast development of new organic sensitizers leads to the need for a better understanding of the complexity and significance of their adsorption processes on TiO{sub 2} surfaces. We have investigated a prototype of the triphenylamine-cyanoacrylic acid (donor-acceptor) on rutile TiO{sub 2} (110) surface with special attention on the monolayer region. This molecule belongs to the type of dye, some of which so far has delivered the record efficiency of 10%-10.3% for pure organic sensitizers [W. Zeng, Y. Cao, Y. Bai, Y. Wang, Y. Shi, M. Zhang, F. Wang, C. Pan, and P. Wang, Chem. Mater. 22, 1915 (2010)]. The molecular configuration of this dye on the TiO{sub 2} surface was found to vary with coverage and adopt gradually an upright geometry, as determined from near edge x-ray absorption fine structure spectroscopy. Due to the molecular interaction within the increasingly dense packed layer, the molecular electronic structure changes systematically: all energy levels shift to higher binding energies, as shown by photoelectron spectroscopy. Furthermore, the investigation of charge delocalization within the molecule was carried out by means of resonant photoelectron spectroscopy. A fast delocalization ({approx}1.8 fs) occurs at the donor part while a competing process between delocalization and localization takes place at the acceptor part. This depicts the ''push-pull'' concept in donor-acceptor molecular system in time scale.

Childhood obesity is a serious global public health concern (WHO, 2015; Wang Y & Lobstein T, 2006). Low self-esteem and related mental health problems are common in obese children (Strauss RS, 2000) as well as poor academic performance and career development (Gurley-Calvez T, 2010).Westernized dietary habits and sedentary lifestyles are identified as the major risk factors of current alarming rate of obesity along with genetic susceptibility (Popkin BM, 1999). Children in many countries, including South Korea, have become increasingly sedentary due to urbanization changes in their respective societies (Ng SW, et al. 2009, Salmon J et al. 2011). In particular, South Korea had abundant dissemination of mobile technology, such as tablet and smart phone devices. Children have become reliant on mobile devices and are less likely to perform physical activities (Do, et al, 2013). Effective and sustainable intervention programs are needed to fight the global obesity epidemic (IOM, 2012; Wang Y et al, 2013; Wang Y et al, 2015). Previous studies suggested focus on prevention strategies that begin in early childhood, a period when children establish their life habits. (Salmon J et al. 2011). Recent systematic reviews and meta-analysis including ours found that obesity prevention programs for young children have a greater intervention effect (Waters E, et al, 2011; Wang Y et al, 2013; Wang Y et al, 2015). The NASA Mission X: Train Like an Astronaut (MX) program was developed to promote children's exercise and healthy eating with excitement for training like an astronaut (Lloyd C, 2012).At present, the NASA MX Program covered 28 countries, enrolled children through their teachers in school setting (MX report 2014, 2015). This pilot study adapted the NASA MX intervention program for young children in South Korea. We assessed its feasibility and effectiveness in promoting physical activity (PA) in children and in improving parents' perspectives. We also examined the status of PA
Tissue Refractive Index Fluctuations Report on Cancer Development
NASA Astrophysics Data System (ADS)
Popescu, Gabriel
The gold standard in histopathology relies on manual investigation of stained tissue biopsies. A sensitive and quantitative method for in situ tissue specimen inspection is highly desirable, as it will allow early disease diagnosis and automatic screening. Here we demonstrate that quantitative phase imaging of entire unstained biopsies has the potential to fulfill this requirement. Our data indicates that the refractive index distribution of histopathology slides, which contains information about the molecular scale organization of tissue, reveals prostate tumors. These optical maps report on subtle, nanoscale morphological properties of tissues and cells that cannot be recovered by common stains, including hematoxylin and eosin (H&E). We found that cancer progression significantly alters the tissue organization, as exhibited in our refractive index maps. Furthermore, using the quantitative phase information, we obtained the spatially resolved scattering mean free path and anisotropy factor g for entire biopsies and demonstrated their direct correlation with tumor presence. We found that these scattering parameters are able to distinguish between two adjacent grades, which is a difficult task and relevant for determining patient treatment. In essence, our results show that the tissue refractive index reports on the nanoscale tissue architecture and, in principle, can be used as an intrinsic marker for cancer diagnosis. [4pt] [1] Z.

Logic design and implementation of FPGA for a high frame rate ultrasound imaging system
NASA Astrophysics Data System (ADS)
Liu, Anjun; Wang, Jing; Lu, Jian-Yu
Recently, a method has been developed for high frame rate medical imaging [Jian-yu Lu, ``2D and 3D high frame rate imaging with limited diffraction beams,'' IEEE Trans. Ultrason. Ferroelectr. Freq. Control 44(4), 839-856 (1997)]. To realize this method, a complicated system [multiple-channel simultaneous data acquisition, large memory in each channel for storing up to 16 seconds of data at 40 MHz and 12-bit resolution, time-variable-gain (TGC) control, Doppler imaging, harmonic imaging, as well as coded transmissions] is designed. Due to the complexity of the system, field programmable gate array (FPGA) (Xilinx Spartn II) is used. In this presentation, the design and implementation of the FPGA for the system will be reported. This includes the synchronous dynamic random access memory (SDRAM) controller and other system controllers, time sharing for auto-refresh of SDRAMs to reduce peak power, transmission and imaging modality selections, ECG data acquisition and synchronization, 160 MHz delay locked loop (DLL) for accurate timing, and data transfer via either a parallel port or a PCI bus for post image processing.
