A number of different but complementary approaches have been used to demonstrate the immunogenicity of Necator americanus acetylcholinesterase to infected individuals. Western blotting of parasite somatic extracts with human post‐infection sera and a specific rabbit antiserum to AChE resulted in the development of almost identical antigen‐recognition profiles. AChE‐containing fractions produced by preparative iso‐electric focusing were subsequently shown to be antigenic in ELISA using post‐infection sera. This preliminary data was reinforced by the affinity‐purification of AChE by immobilized post‐infection IgG, and the immunoprecipitation of AChE activity from ES by post‐infection IgG. Finally, AChE purified by affinity chromatography on edrophonium chloride was shown to be antigenic by Western blotting, and in ELISA, against post‐infection sera, although a degree of re‐activity was also seen with normal human sera. This data is discussed in the context of the host‐parasite relationship.

Abstract The differential transformation method is combined with the dual reciprocity boundary element method to solve the non-Fourier heat conduction problems in functionally gradient materials. The cuckoo search algorithm is improved by the Broyden–Fletcher–Goldfarb–Shanno algorithm to identify the boundary conditions for the heat conduction problems. The polynomial function related to coordinate and time is proposed to approximate the unknown boundary conditions. Numerical examples discuss the influences of measurement point numbers and measurement errors on inverse solutions. Numerical results demonstrate the effectiveness and accuracy of the proposed method.


The pharmacokinetic study of vasicine was conducted on 6 human volunteers after a bolus iv dose of 1.5 mg/kg. The peak plasma concentration of 65±5 μmol/L was obtained at 15 min, and by 4 h only one third of the peak concentration was detected in plasma. These findings correlate well with the clinical studies conducted earlier with vasicine on patients of bronchial asthma.

It has been shown on various animal taxa that magnetic compass
behavior depends on presence and wavelength of light. Crucial
role of short wavelength half of spectrum in magnetoreception
is consistent with process of constitution of radical pairs
consisting of cofactor flavin (FAD) and protein Cryptochrome
(Cry). The investigation of light wavelength and intensity
thresholds for magnetic sensing in vivo gives important data
underpinning experimental identification of radical partners.
To date, only fruitfly and birds wavelength limits were
reported (<420 nm and <565 nm respectively) yet generally
without mapping of color-specific intensity thresholds
throughout the spectrum. Here, we tested spontaneous reaction
to rotations of geomagnetic horizontal vector - magnetically
induced restlessness of German cockroach (Blattella germanica )
under 365, 385, 405, 466 and 520 nm lights and defined
respective light intensity thresholds. Two maxima of
sensitivity have been found at 365 nm UV and 466 nm blue-green
lights. However, even the highest intensities of green 520 nm
light used (10e19 photons s-1m-2) did not support
magnetosensitive behavioral reaction. Our data show spectral
curve of behavioral reaction to geomagnetic field which seem to
be well compatible with Cry light absorption spectrum. Since
both Cry1 and Cry2 have been cloned from Blattella and
molecular approaches are applicable (e.g. gene silencing) our
assay may well be used to decipher open questions of Cry
mediated light-dependent magnetoreception mechanism of animals.


In present study,developmental patterns of Myostatin and Myogenin genes expression in longissimus dorsi(LD)muscle were compared between Erhualian and Large White pigs with semi-quantitative RT-PCR.The results indicated that:(1)the Myostatin mRNA expression in Large White pigs reached a peak at D 20 which was higher than that in Erhualian pigs significantly(P0.05),and Myostatin mRNA expression increased significantly until D_45,no difference between breeds was observed at other ages;(2)the expression of Myostatin increased in both Erhualian gilts and boars after birth,then reached a peak at D 45,and the sexual difference was observed at D_120(P0.05);(3)the development pattern of the expression of Myogenin mRNA was the same in two breeds,the expression of Myogenin mRNA was high at 20 dayold(D_20),then declined gradually;(4)compared with Erhualian boars,the Myogenin expression in Erhualian gilts exhibited remarkable down-regulation at D_90(P0.05).The results suggest that the high level of Myostatin and Myogenin genes expression might play a role in regulating the metabolic and contractile maturation of myofibers during the early postnatal growth;there is strain difference at D_20;around the sex maturation,the sexual difference was found in two genes expression.

Abstract The present study was undertaken to establish the effect of salinity and acclimation time on the oxygen consumption of juvenile white shrimp Litopenaeus vannamei through evaluation of the mechanisms involved in adjustments of respiratory metabolism during acclimation and the effects on the apparent heat increment (AHI). Four experiments were conducted to assess the effect of acclimation time on oxygen consumption of shrimp exposed to salinity changes between 30‰ to 5‰. The effects of a change of salinity were recorded immediately in the first hour and 24 h after change. The results showed that L. vannamei juveniles are well adapted to tolerate salinity changes when they are subjected to sudden change in salinity or are acclimated to salinity change. The effect of salinity on the apparent heat-increment coefficient (AHI-%) in shrimp acclimated over time was also tested. The fasting and feeding oxygen consumptions were increased according to a reduction in salinity, with high values in 5‰ and lower values in 30‰. Although at 15‰ salinity the animals require energy to maintain homeostasis, we believe the juveniles acclimated at that salinity could be more efficient than those acclimated at 5‰ or 30‰ salinity because in that salinity shrimp consumed 1.22 and 1.69 more food than that observed in shrimp acclimated at 30‰ and 5‰, respectively, and without an excessive increase in the costs associated with AHI-%.


This paper analyzes the artistic viewpoints of Choi In-Hoon's novels. The purpose of this paper was to define the tragic thought of Choi In-Hoon's novels, to renew the characteristic of artist in his novels. The artist novels in Choi In-hoon's novels has been appreciated significantly, and the existing study has been indicated that dualism of the main character is a fatal limit. But I can find that the narrative method of dualism of 'sublime' is used to show the artistic viewpoints and involves the point of 'freedom' of the subject. In this, 'necessity' and 'freedom' are based on the life(art) of subjects. Just two aspects of the fundamental conditions indicate that the antagonism between the subject and the other. That situation makes inner splits of subject having a connection with the other(s) causes anguish to each other. The subject has reached an impasse and I explained how to link subject's conduct with 'freedom'. As a result of analysis, I expect to reveal the tragic thought of Choi In-Hoon's novels. Such the tragic thought deserves consider seriously. The subject having it ways could affirm extremes of the antinomy. The ethical responsibility does not exist without freedom of subjects in their 'art'.

Pre-liminary examination and data collection were performedusing a Bruker SMART CCD detector system single-crystalX-ray diffractometer equipped with a sealed-tube X-raysource (40 kV×50 mA) using graphite-monochromated MoKα radiation (λ=0.71073 A). Preliminary unit cell con-stants were determined with a set of 45 narrow-frame (0.3


Elastic parameters such as Young's modulus, Poisson's ratio, and density are very important characteristic parameters that are required to properly characterise shale gas reservoir rock brittleness, evaluate gas characteristics of reservoirs, and directly interpret lithology and oil‐bearing properties. Therefore, it is significant to obtain accurate information of these elastic parameters. Conventionally, they are indirectly calculated by the rock physics method or estimated by approximate formula inversion. The cumulative errors caused by the indirect calculation and low calculation accuracy of the approximate Zoeppritz equations make accurate estimation of Young's modulus, Poisson's ratio, and density difficult in the conventional method. In this paper, based on the assumption of isotropy, we perform several substitutions to convert the Zoeppritz equations from the classical form to a new form containing the chosen elastic constants of Young's modulus, Poisson's ratio, and density. The inversion objective function is then constructed by utilising Bayesian theory. Meanwhile, the Cauchy distribution is introduced as a priori information. We then combine the idea of generalised linear inversion with an iterative reweighed least squares algorithm in order to solve the problem. Finally, we obtain the iterative updating formula of the three elastic parameters and achieve the direct inversion of these elastic parameters based on the exact Zoeppritz equations. Both synthetic and field data examples show that the new method is not only able to obtain the two elastic parameters of Young's modulus and Poisson's ratio stably and reasonably from prestack seismic data but also able to provide an accurate estimation of density information, which demonstrates the feasibility and effectiveness of the proposed method. The proposed method offers an efficient seismic method to identify a "sweet spot" within a shale gas reservoir.

Good explosion effect is one of the important conditions for obtaining high-quality seismic data in desert-grassland area. Because of the thickness and velocity change dramatically in the low-velocity zone, the burial depth of the favorable excitation layer is unstable. The velocity and thickness of near-surface stratification can be obtained from near-surface data, but due to the limited distribution of control points and the limitation of surface survey methods, it is difficult to ensure that the location outside the control points is designed in the favorable excitation layer. In this paper, a design method of shot depth under multi-information constraints is proposed. The near-surface velocity model is determined by multi-information constraints, then the excitation layer velocity of surface area is determined according to the parameters of experimental, and then the optimum shot depth of each point is obtained according to the coordinates of the design shot points. This method can better solve the influence of the inadequate of interpolation accuracy and topographic to the design of shot depth, and improve the condition of seismic and the quality of data.


In order to develop a new type of food source for the effective utilization of fish protein, plastein reaction was applied to improve the functional properties of filefish protein. Plasteins were synthesized from a peptic filefish protein hydrolysate by papain, pepsin, and protease(from Streptomyces griceus) under the optimum conditions of previous paper). Also, L-glutamic acid diethylester and L-leucine ethylester were incorporated into plastein during the plastein reaction by papain. And, General composition, yield, molecular weight, amino acid composition, color and IR spectrum of plasteins were measured. The protein, ash and lipid content of the plasteins were respectively. The yield of plasteins were papain , glutamic acid-incorporated plastein (Glu-Plastein) , and leucine-incorporated plastein (Leu-plastein) . The glutamic acid and leucine content in Glu-plastein and Leu-plastein were , respectively, while the contents in the peptic filefish protein hydrolysate were , respectively. The amino acid compositions were similar to that of the original filefish muscle protein. The major molecular weights of the peptic hydrolysate estimated by gel filteration were 2,000 and 310, and those of plasteihs were 21,000 and 4,900 for papain, 24,000 for pepsin, 18,500 for 6,700 for protease, 24,000 for Glu-plastein and 17,000 for Leu-plastein. The structural changes in freeze-dried filefish meat, the FPC and hydrolysate were not observed on the IR spectrum. But plasteins showed amide I band in range and resulted in a strong band in . The amide I band of Glu-plastein was wider than those of other plasteins and had also a small band at .


To verify the dynamic performance of an MEMS micro tactile probe,a vibration measurement system based on 3D micro positioning device of Suss Microtec and piezo of PI was constructed.Under low frequency vibration stimuli with different amplitudes,the responses of vertical and transverse directions were tested.The repeatability during short term measurement was studied.Nonlinear errors of curve of displacement of probe and output voltage are less than 0.102% and 0.507% under vertical and transverse modes respectively.


The efficacy of using gloves by the general population to prevent COVID-19 is unknown. Despite not having evidence to support its use, a large number of people have decided to use them, and governments and media don't have a clear message about using gloves by the general population. If we also consider the shortage of medical supplies, it's crucial to determine the efficacy of routine glove use by the general population in preventing COVID-19. Using innovative and agile processes, taking advantage of technological tools, and resorting to the collective effort of several research groups, this living systematic review aims to provide a timely, rigorous and continuously updated summary of the evidence available on the the efficacy of the use of gloves in the prevention of COVID-19 disease in healthy population.


We present a method for humanoid robot walking on partial footholds such as small stepping stones and rocks with sharp surfaces. Our algorithm does not rely on prior knowledge of the foothold, but information about an expected foothold can be used to improve the stepping performance. After a step is taken, the robot explores the new contact surface by attempting to shift the center of pressure around the foot. The available foothold is inferred by the way in which the foot rotates about contact edges and/or by the achieved center of pressure locations on the foot during exploration. This estimated contact area is then used by a whole body momentum-based control algorithm. To walk and balance on partial footholds, we combine fast, dynamic stepping with the use of upper body angular momentum to regain balance. We applied this method to the Atlas humanoid designed by Boston Dynamics to walk over small contact surfaces, such as line and point contacts. We present experimental results and discuss performance limitations.


In the last decade, social media have become widely exploited sources of information concerning every aspect of life. The reason is that they permit to create and widely share information, even in mobility by exploiting mobile apps. Information available on social media are often related to public places (restaurants, museums, etc.), and users often look for interesting public places. Currently, various social media own and publish huge and independently-built corpora of geo-located data about public places, which are not linked each other. In particular, the main players are Google and Facebook. Users searching for a public place of interest (POI) might wish to get all available information from social media. Therefore, they need an on-line aggregation engine for public places that returns an aggregated view of a place, retrieving data concerning the same place from various sources. The on-line approach is suggested by continuous variations in data within the on-line corpora, that demands for a technique that cannot rely on off-line processing. In this paper, we address the problem by devising a novel technique to aggregate geo-located data about public places; the application context is to associate data provided by Google Places with Facebook pages concerning public places; the Klondike software tool implements this technique. Tests were conducted on a data set containing about 300 public places in Manchester (UK).

Wireless reprogramming is the process of writing and updating new code or modifying the characteristics of subsisting code for a wireless sensor networks. For security reasons, every code modification must be authenticated to prevent the attacker from installing malicious code in the wireless sensor networks. The existing reprogramming protocol SDRP is based on the distributed reprogramming approach in which one of the security requirement data confidentiality is major issue. In some applications, data are also required to be kept confidential due to the possibility of message interception. The proposed distributed reprogramming protocol supports confidentiality, provides security protection for reprogramming and resistance to the intruder attacks that exploit the distributed reprogramming protocol. The reprogramming protocol uses user level individual authentication for group of cluster to ensure the data confidentiality. In-network data aggregation process applied to summarize the resultant data which enhance the robustness and accuracy of information obtained by entire network. Another advantage is that it reduces the traffic load and conserves energy of the sensors.


In 2012-2014, the germination ability of lemon balm seeds were tested. The investigated seeds were obtained from the lemon balm breeding project conducted at the Institute of natural Fibres & Medicinal Plants of Poznan, Poland. The germination rate was done by using ISTA seed germination rules and the high fluctuation of germination rate was observed. Low rate of germination usually disqualificates the seed material. Thus, the anatomy of the investigated lemon balm seeds was analyzed by scanning electron microscopy (SEM) and tetrazolium test was done. SEM analysis showed accurate morphological structure of all seed parts. The embryos, endosperm and testa were well and correctly developed. Seed coat was typical for all species of Lamiaceae. Abnormal seed part were not found. Tetrazolium test revealed the high rate of vitality of the investigated strain seeds. Thus, other useful tests should be recommended before seed disqualification will be done in case of low germination rate.

Occludin (OCLN) is an important component of the tight junction complex, providing apical intercellular connections between adjacent cells in endothelial and epithelial tissue. In 2010 O'Driscoll et al reported mutations in OCLN to cause band‐like calcification with simplified gyration and polymicrogyria (BLC‐PMG). BLC‐PMG is a rare autosomal recessive syndrome, characterized by early onset seizures, progressive microcephaly, severe developmental delay and deep cortical gray matter and basal ganglia calcification with symmetrical, predominantly fronto‐parietal, polymicrogyria. Here we report 4 additional cases of BLC‐PMG with novel OCLN mutations, and provide a summary of the published mutational spectrum. More generally, we describe a comprehensive molecular screening strategy taking into account the technical challenges associated with the genetic architecture of OCLN, which include the presence of a pseudo‐gene and copy number variants.

Let P'.112,+i(z) be the associated Legendre function of order m and degree 1/2 + ix. We give, here, two integral transforms Gm and Hm, arising naturally from the generalized Mehler transform, which is induced by Pm 1/2 + ,(cosh y), such that HmGm = Identity (formally). We show that if 1 <p < oo, -/p < a < 1lp, m < 1/2 or m = 21, 2 ., then 11 Gmf II,p, _ Am,,, Ilf II,p, and 11 Hmf p Am Ilf 11 p,., where"" denotes the Fourier cosine transform. We also prove that Gmf, Hmf exist as limits in LP'a of partial integrals, and we prove inequalities equivalent to the above pair: 11GmfIp,, ?Am.IfIp a, and IIHmf llp,a?Amalfllp,p. These we dualize to II(Hmf)'IIp,_aAm,aIfIp,a and Il(Gmf)^IIPa Am aIIf Pa Gm and Hm are given by Gm(f; y) f f f(x)Km(x, y) dx and Hm(f; x) =f J f(y)Km(x, y) dy (O _y < oo), where Km(x, y) = I.f(1/2-m-ix)/TI(-ix)I(sinh y)112Pa 1/2 + i(cosh y). The principal method of proving the inequalities involves getting asymptotic expansions for Km(x, y); these are in terms of sines and cosines for large y, and in terms of Bessel functions for y small. Then we can use Fourier and Hankel multiplier theorems. The main consequences of our results are the typical ones for transplantation theorems: mean convergence and multiplier theorems. They can easily be restated in terms of the more usual Mehler transform pair g(y) = f(X)P 1/2 + ix(Y) dX and f(x) = lr1x sinh ffx-1(1/2-m+ix) 1(1/2-m-ix) f g(Y)P12+iX(Y) dy.


The refractive index (Zeiss Abbe Model A) was compared to percentage-protein. (Technicon autoanalyzer) and percentage-solids (oven dried, 108° C. for one hour) in 505 samples of egg white. The linear regression and correlation parameter estimates indicated that the refractive index is a better predictor of percentage-pr otein than solids, although percentage-protein and percentage solids are highly correlated.

Objective
To analyze and summarize the ultrasonographic features of fibrolamellar hepatocellular carcinoma (FLHCC).

Methods
The ultrasound images were retrospectively analyzed in 23 FLHCC cases which were confirmed by pathology, including the size, echogenicity, boundary and other features on gray scale ultrasound, color Doppler flow imaging and enhancement patterns on contrast-enhanced ultrasound (CEUS).

Results
Twenty-three patients had 23 lesions of FLHCC. The average age was (40.0±17.1) (15-77) years old and among them 3 cases had liver cirrhosis(13.0%). The maximum diameter of FLHCC lesions was 2.5-16.7 cm and the average was (7.2±4.3)cm. On gray scale ultrasound, 82.6% (19/23) lesions were hypoechoic, 78.3% (18/23) lesions showed cord-like or sheet-like hyperechoic area and 47.8% (11/23) lesions displayed strip-like echogenic attenuation in the center, with calcification in 17.4% (4/23) lesions. There were 91.3% (21/23) lesions showed peripheral and internal rich color flow signals on color Doppler flow imaging and 60.9% (14/23) with subcapsular thick blood vessels. All 8 FLHCC lesions displayed early and hyper-enhancement in the arterial phase and wash-out in the portal and delayed phases on CEUS. Internal nonenhanced scar-like area was appeared in all lesions on CEUS.

Conclusions
Patients with FLHCC are mostly young and few with liver cirrhosis. Ultrasonographic features are characterized by relatively large-sized mass with internal acoustic attenuation or calcification on gray scale ultrasound and hypervascularity with central scar on CEUS.

Key words:
Ultrasonography; Carcinoma, hepatocellular; Contrast-enhanced ultrasound

We study the existence problem of harmonic maps with potential from $\mathbb{R}^2$ into $S^2$. For a specific class of potential functions on $S^2$, we give the sufficient and necessary conditions for the existence of equivariant solutions of this problem. As an application, we generalize and improve the results on the Landau-Lifshitz equation from $\mathbb{R}^2$ into $S^2$ in \cite{G_S} due to Gustafson and Shatah.

Dissolution temperatures Ts have been determined for poly(vinyl alcohol) (PVA) samples of varying tacticity as a function of crystallization temperatures Tc. From the values of Ts and Tc, one can obtain values of (Tm)∞, the dissolution temperature of crystals of infinite stepheight. (Tm)∞ is a characteristic property of a given sample. This method of characterization is very sensitive and reliable for detecting differences in molecular regularity among PVA samples. The variation of (Tm)∞ with stereoregularity is attributed in part to differences in hydrogen-bonding characteristics. Determinations of the crystallinities of solution-crystallized PVA have shown that stereoregularity in PVA does not result in higher crystallizability.


Finding all possible UV resonances of effective operators is an important task in the bottom-up approach of effective field theory. We present all the tree-level UV resonances for the dimension-5, -6 and -7 operators in the Standard Model effective field theory (SMEFT), and then obtain the correspondence between the UV resonances and the effective operators from the relations among their Wilson coefficients, through the functional matching and operator reduction procedure. This provides a cross-dimension UV/IR dictionary for the SMEFT at tree-level, and the methods used here, especially the on-shell construction of general UV Lagrangian and the systematic reduction of operators, are extendable for UV resonances of $d \geq 8$ operators in SMEFT and other EFTs.


To explore whether fibrocalculus pancreatic diabetes (FCPD) is purely of secondary type, 8 early FCPD patients (Age in years 25 ± 5; BMI - 19.54± 2.98, mean ± SD) were compared to 20 (Age 21 ± 6, BMI -17.97 ± 3.65) tropical calcific pancreatitis (TCP) patients, for their glycemic status (fasting and 2hr postprandial glucose, by glucose-oxidase method), insulinemic status (fasting and 2hr C-peptide and Insulin by ELISA) and pancreatic morphology (by ERP). Fasting serum glucose (6.28 ± 2.25mmol/l, mean ± SD) of FCPD subjects were only marginally higher than normal; however 2hr glucose levels showed considerable degree of hyperglycemia (15.21 ±2.84). FCPD subjects had very low fasting (TCP: 0.5±0.12, FCPD: 0.25±0.14 nmol/l, mean ± SD) and postprandial (TCP: 1.15 ±0.53, FCPD: 0.70±0.34) serum C-peptide. Analysis of C-peptide-glucose ratio (Fasting - 0.12 ± 0.05 in TCP vs 0.05 ± 0.03 in FCPD, mean ± SD; Postprandial - 0.17 ± 0.09 in TCP vs 0.05 ±0.03 in FCPD) revealed that capacity of increasing insulin secretion to meet the demands of hyperglycemia is almost nil in FCPD patients. This pattern was also reflected in absolute insulin values and analysis of insulin-glucose ratios. ERP could be successfully done in 13 TCP and all the FCPD patients. In contrast to sharp demarcation of TCP and FCPD subjects regarding their endocrine functional status, 12 (92.7%) out of 13 TCP and all 8 (100%) FCPD patients had severe degree of ductal damage. The results suggest that endocrine dysfunction and generalized exocrine pancreatic damage do not follow a straight-line relationship in TCP and FCPD patients and thus, FCPD does not seem to be a purely secondary form of diabetes.

The development of effective ozone control strategies requires the use of atmospheric models. There is general agreement within the scientific community that several aspects of the chemistry within these models has yet to be fully elucidated, and is influential in their predictions. The work in this thesis is aimed at trying to determine some of the unknown aspects of the mechanisms of important atmospheric species. Specifically, the gas-phase reactions of two large alkanes, 2,2,4-trimethylpentane and 2,2,5-trimethylhexane are investigated. These two alkanes are present in urban air, and are potential aerosol precursors. The chemistry of several aromatic hydrocarbons are also studied using both theoretical and experimental techniques. The effects of NO2 on the photooxidation of toluene, m-xylene, and p-xylene are examined, and mechanisms of each of these organics are thouroughly evaluated through closely coordinated laboratory work and computer modeling. In addition, product studies of the photooxidation of 1,2,4-trimethylbenzene and m-ethyltoluene are conducted. These studies provide the first identification of ring-retained products from 1,2,4-trimethylbenzene, and ring-retained and fragmented products from m-ethyltoluene.

A new indoor experimental reactor was designed to investigate gas-phase reaction kinetics and mechanisms. This new system has served to launch the atmospheric chemistry program at Caltech into a wide variety of new research topics.


According to the field geological characteristics and petrology of the Taima rock body(now known as Taima rockdome) which is the main body of Shiwandashan rock belt,the authors consider that the Taima rock body consist of porphyroclastic lavas and is an eruptive facies but not an intrusive phases of granite porphyries.Combined with the surrounding volcanic rocks,intrusive rocks and strata,the Taima rock body is considered as a dome of the central part of the central fissure type volcanic structure.Therefore,the Shiwandashan rock belt is a volcanic-intrusive complex rocks belt,and the Taima porphyroclasts lava is one of the phases in that belt.


To promote environmental sustainability it is urgent, in all segments of society, the review of how water consumption is done and, especially, the adoption of practices and technologies to make better use of this resource and decreasing waste. In public school units is frequent the inappropriate use and also loss of water by conservation conditions of hydro-sanitary systems. The paper presented here is conducted to question about how water consumption is conducted in public schools in the region of Triangulo Mineiro. The aspects studied were separated by sector (bathroom, kitchen, indoor and outdoor area), which included the identification of water consumption, the practical procedures for cleaning and maintenance and the habits of users. Understanding the main aspects related is taken as main reference to proposition of guidelines in environmental education projects for the water rational use.


We present computer simulations to examine probability distributions of gyration radius for the no-thickness closed polymers of N straight segments of equal length. We are particularly interested in the conditional distributions when the topology of the loop is quenched to be a certain knot, K. The dependence of probability distribution on length, N, as well as topological state K are the primary parameters of interest. Our results confirm that the mean square average gyration radius for trivial knots scales with N in the same way as for self-avoiding walks, where the cross-over length to this "under-knotted" regime is the same as the characteristic length of random knotting, N_0. Probability distributions of gyration radii are somewhat more narrow for topologically restricted under-knotted loops compared to phantom loops, meaning knots are entropically more rigid than phantom polymers. We also found evidence that probability distributions approach a universal shape at N>N_0 for all simple knots.


The contemporary science of materials and condensed-matter physics is changing in response to a new awareness of the relevance of concepts associated with complexity. Scientists who design and study new materials are confronted by an ever-increasing degree of complexity, both in the materials themselves and in their synthesis. Typically, modern advanced materials are partially non-crystalline, often multicomponent, and form out of equilibrium. Further, they have functional and structural properties that are active over several length-scales. This emerging structural and functional complexity is intrinsic and necessary to many aspects of modern materials; features common also to several other complex systems. In this paper we briefly review the emerging structural complexity in a special model system: sphere packings.


The engineering drawing has the characteristics of practicality, abstraction and spatiality. To make the engineering drawing teaching meet the requirement of times, it is necessary to change the traditional teaching mode of "hanging drawings, writing on blackboard and giving models" and put the teaching idea of fostering students' creative ability into the engineering drawing teaching. We should make full use of the modern teaching medium to train students' innovative ability through carefully designing the teaching project and creative exercises.


Due to the availability of advanced image editing tools, existing image hashing techniques for image content authentication needs to be enhanced. Some of the recent better existing techniques based on ring partition cannot explore the complete content information available in the image. It is observed that around 50% of the corner information of the image remains unexplored. This paper presents an image hashing technique that tries to make use of corner information to generate the hash, which is more robust and discriminative than the existing ring partition based techniques. The algorithm based on ring partition and invariant vector distance that generates hash using intensity channel has been used to prepare the baseline system. The baseline system is extended by including the corner information of the intensity channel to develop the proposed model. It also uses the central orientation of the original image to make the system rotation invariant. The receiver operating characteristics (ROC) shows that the proposed model outperform some of the state-of-the-art methods.


valentin - Compress Me, Stupid!

Compression is a technique to reduce the number of bits needed to
represent a given dataset. A very common use-case in the distributed
digital age is to reduce the size of files in order to reduce the time
and bandwidth requirements of sending a file from one location to
another.

There are a large variety of different algorithms and implementations of
so called "codecs" - a term is derived from the fact that programs that
implement a compression algorithm commonly constitute of both a
compressor and a corresponding decompressor. There are many different
special purpose compressors that exploit specifics in the structure of the
input data, for example: MP3, Ogg and FLAC for audio data such as music,
GIF, JPEG and PNG for images and MPEG for encoding video. Also, there
are many general purpose codecs that make no assumptions about the
structure of the data, for example: Zlib(DEFLATE), Bzip2(BWT) and LZMA.

However, and due to the ever growing divide between memory access latency and CPU clock
speed a new use-case beyond faster file transfers and more efficient use
of disk-space has emerged: "in-memory compression".

Keeping data in RAM that is compressed also means that the CPU has to
do more work in order to make use of it. However, if the compressor
is fast enough, this decompression overhead could pay off, and
applications could work with compressed data transparently, and so not
even noticing the slowdown due to the extra effort for
compression/decompression.

This technique can be very beneficial in a variety of scenarios where
RAM availability is critical. For example, in-memory caching systems
like Memcached or Redis could store more data using the same resources
thereby optimizing resource usage. Another use case is to use
compression for in-memory data containers, a la NumPy's ndarray or
Pandas' DataFrame, allowing for improved memory usage and potentially
allow for accelerated computations.

In our talk, we will explain first why we are in a moment of computer
history that [in-memory compression can be beneficial for modern
applications] [1].

Then, we will introduce [Blosc] [2], a high speed
meta-compressor, allowing other existing compressors (BloscLZ, LZ4,
Snappy or even Zlib) to leverage the SIMD and multithreading framework
that it provides and help achieving extremely fast operation
(frequently faster than a plain memcpy() system call).

Finally, we will show some existing data handling libraries ([Bloscpack] [3], [PyTables] [4], [BLZ] [5]) -- all written in Python -- that
already use Blosc today for fulfilling the promise of faster operations by
doing in-memory compressing.

This paper discusses generalization bounds for complex data learning which serve as a theoretical foundation for complex support vector machine (SVM). Drawn on the generalization bounds, a complex SVM approach based on the Szegő kernel of the Hardy space H2(𝔻) is formulated. It is applied to the frequency-domain identification problem of discrete linear time-invariant system (LTIS). Experiments show that the proposed algorithm is effective in applications.


The complete multipartite graph Kn(2t) having n partite sets of size 2t, with n ≥ 6 and t ≥ 1, is shown to have a decomposition into gregarious 6-cycles, that is, the cycles which have at most one vertex from any particular partite set. Complete sets of differences of numbers in Zn are used to produce starter cycles and obtain other cycles by rotating the cycles around the n-gon of the partite sets.


Using statistic data of the cotton production and results of the national cotton variety test in Yellow River region from 1973 to 2000, cotton genetic improvement efficiency on different characters of cotton variety was analyzed, and major breeding achievements were concluded. The results indicated that breeding efficiency on yield decreased, whereas increased on resistance to diseases,pest,drought and some indices of fiber quality properties. The approach for increasing cotton genetic on improvement efficiency was studied. Since American bred trans-genie cotton played an important role in Yellow River cotton producing region,it is urgent to extend native-bred cotton varieties.


Adaptation of new habits in many aspects of life, including education, is required amid the COVID-19 outbreak. Many countries, including Indonesia, suddenly implement online learning as a realization of social distancing policies. This sudden change in the learning system has become a challenge for teachers. They must be able to integrate technology, pedagogy, and content knowledge to conduct online learning well. Therefore, this study investigates the readiness of biology teachers to face online learning based on their Technological Pedagogical Content Knowledge (TPACK). The purposive survey method was used by distributing questionnaires and conducting online interviews. The questionnaire consists of 30 statements about the TPACK readiness of biology teachers and ten questions about the online learning process during the COVID-19 outbreak. A total of 121 biology teachers in West Java, Indonesia, participated in this study. The findings indicate that biology teachers have sufficient TPACK skills in implementing online learning. However, their technological capabilities still need to be improved. The flexibility of place and time, availability of learning resources, and increased independence of teachers and students in using technology are the advantages of online biology learning during the COVID-19 outbreak. Meanwhile, the problems faced by teachers include technical connectivity and student honesty in taking exams in the implementation of online learning. The uncertainty of when the pandemic will end makes this study important to carry out for evaluation and potential improvement of online biology learning systems.


Density functional theory calculations with the B3LYP-D function have been performed to investigate the mechanism of carbonyl hydrosilylation reactions catalyzed by the high-valent nitridoruthenium(VI) complex [RuN(saldach)(CH3OH)]+[ClO4]− (1; saldach is the dianion of racemic N,N′-cyclohexanediylbis(salicylideneimine)). Our computational results indicate a favored ionic outer-sphere mechanistic pathway. This pathway initiates with a silane addition to the RuVI center, which proceeds through a SN2-Si transition state corresponding to the nucleophilic attack of the carbonyl on the silicon center. This attack then prompts the heterolytic cleavage of Si–H bond. The rate-determining energy of the SN2-Si transition state is calculated to be 22.9 kcal/mol with benzaldehyde. In contrast, our calculations indicate that the initial silane addition to the nitrido ligand does not represent an intermediate of the catalytic process leading to the silyl ether products, since it involves high-energy transition states (2...


This book conducts a multidimensional study of the phenomenon of innovation transfer using the example of wikis based on Web 2.0 within a large and complex chemical pharmaceutical company. In this context, innovation transfer is understood to be a social and organisational process used for successful problem-solving by transferring a proven solution to a previous problem onto a new problem. The study's results reveal that the success of such innovation transfer not only depends on the objective material requirements of the business value adding activity in question, but also requires an understanding of the differing subjective interests involved. Assessing the transfer's success not only involves considering the criteria of technical efficiency and economic profitability, but also social acceptance. In negotiations, a compromise is sought in order to develop a social and organisational innovation from a range of technical functions. Here, the ability to act in a given situation plays a particular role. If both the negotiations and the compromise fail, the transfer of innovation fails as well.


In a recent article, Zemblys et al. [1] reported on a new method for the classification of eye-movements using deep neural networks. I will refer to this paper as the "gazeNet paper". I have found 2 errors and two problems with that paper that are explained herein. Error 1: The gazeNet machine-learningbased classification method was built assuming that a hand-scored dataset from Lund University was all collected at 500 Hz, but in fact, six of the 34 recording files were actually collected at 200Hz. Of the six datasets that were used as the training set for the gazeNet algorithm, 2 were actually collected at 200Hz. Problem 1 has to do with the fact that even among the 500Hz data, the inter-timestamp intervals varied widely. Problem 2 is that there are many unusual discontinuities in the saccade trajectories from the Lund University dataset that make it a very poor choice for the construction of an automatic classification method. Error 2 arises out of the novel event-related agreement analysis employed by the gazeNet authors. Although the authors intended to classify unmatched events as either false positives or false negatives, many are actually being classified as true negatives. True negatives are not errors, and any unmatched event misclassified as a true negative is actually driving the kappa statistic higher, whereas unmatched events should be driving the kappa statistic lower.


The Woxi Au‐Sb‐W deposit is one of the largest polymetallic ore deposits in the Xuefengshan Range, southern China, hosted in low‐grade metamorphosed Neoproterozoic volcaniclastic rocks. The orebodies of the deposit are predominantly composed of banded quartz veins, which are strictly controlled by bedding and faults. Petrographic observations and geochemical results are reported on the occurrence of Au and properties of the ore‐forming processes for different stages in the deposit. The veins extend vertically up to 2 km without obvious vertical metal zoning. The ore‐forming process can be subdivided into four mineralization stages: Pre‐ore stage; Early stage (scheelite‐quartz stage); Middle stage (pyrite‐stibnite‐quartz stage); and Late stage (stibnite‐quartz sage). Four types of pyrite (Py0, Py1, Py2, and Py3) were identified in the ores and host‐rock: Py0 occurs as euhedral grains with voids in the core, ranging in size from 50 to 100 μm and formed mainly in the Pre‐ore stage and Early stage; Py1 occurs as subhedral grains. Small grains (around 10 μm) of Py1 form irregularly shaped clusters of variable size ranging from tens to hundreds of μm and mainly formed in the Middle stage; Euhedral‐subhedral fine‐grained Py2 formed in the Late stage; Minor subhedral fine‐grained Py3 was deposited in the Late‐stage. Stibnite is widely distributed in the Middle and Late stage ore veins. No systemic difference was recognized in mineralogical features among stibnite formed in different stages. In addition to native gold, the lattice bound Au+1 widely exists in Py1 and Py2 in the deposit, and widespread Py1 is considered as the main Au‐bearing mineral with the highest Au contents. Most elements (such as Co, Ni, Cu, As, Sb, Ba, and Pb) are considered to occur as solid solution within the crystal lattice and/or invisible nanoparticles in sulfides minerals. The Co/Ni ratio of most pyrite is lower than 1, suggesting that the metals in the ore‐forming fluid are sourced from sedimentary rocks. The coupled behavior between Au and As; Au and Sb suggests that the substitution of As and Sb in pyrite can enhance the incorporation of Au. Variation of trace elements in pyrites of different stages suggests some information on the mineralization processes: Large ion lithophile elements (such as Ba and Pb) are enriched in Py0 indicating that water‐rock reaction occurred in the Early stage; Fine‐grained Py1 with a heterogeneous distribution of elements suggests fast crystallization of pyrite in the Middle stage.


A multigrid algorithm for implementation on unstructured meshes is proposed. The algorithm uses a sequence of unnested grids and requires the development of efficient inter-grid interpolation procedures. It is demonstrated how elliptic problems can be solved in this fashion by using Jacobi smoothers.


In order to simplify the computation complexity for traditional single integral equation in electromagnetic scattering from dielectric objects, a new single integral equation was proposed. The numerical results of RCS (radar cross section) obtained from several dielectric objects with large permittivity are in agreement with the exact results. Furthermore, the calculation amount is reduced apparently and the singularity of the integral core is weakened. The validity of the new single integral equation was also


Objective:To explore the configurational changes of nuclear matrix-intermediate filament(NM-IF) system during differentiation of human hepatocarcinoma SMMC-7721 cells in vitro after being induced by hexcamethylamine bisacetamide(HMBA).Methods:SMMC-7721 cells treated with or without HMBA were cultured and then treated by selective extraction method and prepared for whole mount electron microscopy observation.The samples were examined under light and transmission electron microscope respectively.Results:It can be seen that the nuclear matrix-intermediate filament(NM-IF) in SMMC-7721 cells were relatively few and arranged irregularly.The nuclear lamina was nonuniform,and the two kinds of filaments connected were relaxed and not tightly.One or more residual nucleoli which maintained by a small quantity of fibres cccurred in the nucleus.After being induced by HMBA,the NM-IF filaments were dense and distributed uniformly.The heterogeneous population of filaments,included highly branched ultrathin filaments were also appeared in the regular meshwork.The connection between the two kinds of filaments and the relatively thin,condensed and sharply demarcated lamina composed of intermediate-sized filaments was relatively fastened.And the residual nucleoli were connected with relatively abundant filament bundles.Conclusion:It is implied that the NM-IF system in SMMC-7721 cells had been undergone a restorational change similar to that of normal cells after HMBA treatment,and this alternation is an important morphological and functional indication of the reversion of cancer cell.

50 nm Magnetic nanocluster (MNC) was deliberately selected as an efficient probe for the magnetic relaxation switching (MRSw) assay. After surface modification of MNCs with poly(acrylic acid) to give PAA-MNCs, and employing streptavidin-biotin interactions for the MRSw assay model, a few tenths pM concentration of strepavidin could be determined.


In wide-ranging information society, fast and easy access to information in language of one's choice is indispensable, which may be provided by using various multilingual Natural Language Processing (NLP) applications. Natural language text contains references among different language elements, called anaphoric links. Resolving anaphoric links is a key problem in NLP. Anaphora resolution is an essential part of NLP applications. Anaphoric links need to be properly interpreted for clear understanding of natural languages. For this purpose, a mechanism is desirable for the identification and resolution of these naturally occurring anaphoric links. In this paper, a framework based on Hobbs syntactic approach and a system developed by Lappin & Leass is proposed for resolution of reflexive anaphoric links, present in Urdu text documents. Generally, anaphora resolution process takes three main steps: identification of the anaphor, location of the candidate antecedent(s) and selection of the appropriate antecedent. The proposed framework is based on exploring the syntactic structure of reflexive anaphors to find out various features for constructing heuristic rules to develop an algorithm for resolving these anaphoric references. System takes Urdu text containing reflexive anaphors as input, and outputs Urdu text with resolved reflexive anaphoric links. Despite having scarcity of Urdu resources, our results are encouraging. The proposed framework can be utilized in multilingual NLP (m-NLP) applications.

In Zuoqiuming's Records, a great deal of supplements and amendments were made for the records of celestial phenomena written in the manuscripts of the Spring and Autumn annuals as follows:1.It pointed out the wrong time of records on several solar eclipses made by historians in Lu State and the mistakes on"non-sacrificial rites on the first day of leap month". 2.On the basis of the Spring-Autumn Equinoxes and the Summer-winter solstices,the Beginnings of Spring,Summer,Autumn, and Winter as well as the Waking of Insects were added so that the Solar Terms turned into nine ones. 3.The appearance of Jupitor calendar indicated the unitary trend of Calendar system. 4.On the harmony between the heavenly stars and the earthly areas,the struggle between science and superstition was objectively recorded. These offer rich historical materials on astronomy for us to research the Spring and Autumn Calendar System.


The present paper describes an investigation that implements and assesses a dynamic continuum constitutive law for all-metallic sandwich panels. It also demonstrates its application to multilayer panels subject to water blast. Finite element calculations of unit cells are used to calibrate the model, especially the hardening curves at different strain rates. Once calibrated, the law is assessed by comparison with two sets of experiments. The dynamic response of panels impacted by Al foam projectiles at impulses comparable to those expected in water blast. The response of a multilayer core to an impulse caused by an explosion occurring in a cylindrical water column. The comparisons reveal that the overall deformation, average core strain, peak transmitted pressure, and velocities of the front and back faces are adequately predicted, inclusive of fluid/structure interactions. The inherent limitations of the approach are the underprediction of the plastic strains in the faces and incomplete assessment of stress oscillations beyond the peak. The former deficiency would pertain for any continuum representation for the core and would lead to problems in the prediction of face tearing. The latter may adversely affect the predictions of the impulse.


THE extent and severity of atherosclerosis of the aorta shows a highly significant correlation with the total cholesterol content of its wall' but not with the serum cholesterol.2 This has suggested the possibility of some factors in the vessel wall that may affect the deposition of lipids in the intima. We have studied the lipidand the cholesterol-binding capacity of intimal globulins in relation to the degree of aortic atherosclerosis.


The rate of population growth in Lubuklinggau City continues to increase every year, this is a factor in the increasing demand for electricity. The development of the number of PLN customers in Lubuklinggau City in 2017 was 90.606 customers, increasing to 120.809  customers in 2021. PLN must be able to predict the number of electricity customers in the future in order to provide electricity needs. One of the forecasting models that can be used to predict the development of the number of PLN electricity customers is the Simple Linear Regression model. Simple Linear Regression is a forecasting model based on the effect of the causal variables on the effect variables. The variables used are the population variable and the number of PLN customers. From these two variables, the process of analyzing the influence of population on the number of PLN customers in the future will be carried out. The results showed that 90% increase in population affects the number of PLN customers. With the prediction of the development of the number of customers, PLN Lubuklinggau can prepare the necessary facilities and can estimate how much additional power and electrical energy will be in meeting customer needs in the future.


We consider the propagation of electromagnetic waves in one-dimensional periodic structures composed of alternating layers of negative index metamaterial and semiconductor. We study the bandgap properties of periodic structure semiconductor - dispersive negative index metamaterial.


With the continuous development of offshore engineering, major offshore projects develop rapidly. During the development of offshore engineering, different degrees of noise will be generated, and the man-made noise can have harmful effects on marine mammals. Currently, The researchers usually use Passive Acoustic Monitoring(PAM) method to monitor the marine mammals. However, it is impossible to acquire, monitor and analyze the sound of marine mammals in real time and lack of comprehensive information of marine mammals monitoring, and the data analysis and study of vocalization rules can only be carried out after data collection is completed and equipment is recovered. Therefore, this paper proposes a real-time automatic detection and classification technology to monitor targeted marine mammals efficiently and continuously timely in offshore engineering areas.

Presented paper is focused on numerical simulation of turboprop engine cooling in the section of a gas turbine. The method of heat transfer motor cooling by natural convection and radiation is described. The heat transfer in gas turbine section is represented on a simplified double annular geometry. Numerical data were compared with data that was gained from measuring on an experimental stand. The surface temperatures of the tubes were measured on the experiment stand during the cooling of the engine model. Numerical and experimental results reach a good agreement and will be further applied to the study of temperature-dependent deformation of aircraft engine parts, which have a significant effect on the safety and flawless operation of the aircraft engine.


Broad-area graded-index separate-confinement-heterostructure (GRIN-SCH) diode lasers were fabricated with a single 10-nm-thick Al/sub 0.07/Ga/sub 0.93/As quantum-well active layer. For the characteristics measured during pulsed operation of 175-192 lasers with a cavity length of 500 mu m, distributed over a 16 cm/sup 2/ wafer, the mean values and standard deviations are, respectively: threshold current density 288 and 11.3 A/cm/sup 2/; differential quantum efficiency 83.0 and 2.5%; and emission wavelength 804.9 and 0.6 nm. For lasers from ten wafers grown under the same nominal conditions, the wavelengths range from 803.5 to 807.4 nm.<<ETX>>


In this paper we are concerned with the heteroscedastic regression model y i = x i β + g ( t i ) + σ i e i , 1 ≤ i ≤ n under correlated errors e i , where it is assumed that σ i 2 = f ( u i ) , the design points ( x i , t i , u i ) are known and nonrandom, and g and f are unknown functions. The interest lies in the slope parameter β . Assuming the unobserved disturbance e i are negatively associated, we study the issue of strong consistency for two different slope estimators: the least squares estimator and the weighted least squares estimator.


The random walk (RW) is one of the effective sampling methods for large-scale networks such as the Internet and social networks. While a simple RW method tends to visit nodes with high degrees, the Metropolis-Hastings random walk (MHRW) algorithm has ready-to-use characteristics, wherein the nodes visited by the algorithm distribute uniformly. However, because the MHRW algorithm conducts many self-looping operations and the spread of its crawler is slow, it requires many samples in order to secure sufficient accuracy. This study proposes a RW that requires less self-looping than MHRW did while maintaining the ready-to-use characteristics. The ready-to-use characteristics are achieved by appropriately changing the adaption probability of MHRW and choice probability of neighboring nodes. Our experiments demonstrated that the proposed RW required less self-loop operations than MHRW did. Moreover, the cost of the proposed algorithm is discussed keeping applications to real networks in mind.


Change and growth are development's expression in industry, the emergence and the disappearance are reflected in firms´ dynamics. This article refers to the study of the industrial dynamics starting at the conjunction of three analysis bases: the industrial organization that gives information about market's structure, the combination of productive factors and the firm's behavior; the economic geography, as a recognition of time and space importance in economics and social processes; and, as integrating element, the territorial politics materializes into possibilities for regional development and, inside it, firms´ development.


The high productivity, nutrient retention, and stability (resistance and resilience in response to pests, pathogens, and invasive weeds) observed in natural systems are frequently attributed to their high diversity (Tilman, 2000). High productivity, nutrient retention, and stability are also associated with ecosystem sustainability. In much of the temperate world - as also in parts of the tropics - these aspects of ecosystem functioning have been achieved in highly simplified human-managed systems through subsidies in the form of fertilizers and pesticides. Over much of the tropical world, however, such fossil-energy-based subsidies continue to be an economically unviable option. Understanding the ecological underpinnings of the
diversity-functioning relationship, therefore, is crucial to the design of sustainable human-managed tropical systems.


Abstract : Lithium-ion batteries are the common technology for powering portable electronics. The nuclear reactions within the batteries are sensitive to neutrons. By characterizing this dependence, neutron dose and fluence information can be determined. The dose information can be used on an individual basis to provide forensic information including evidence for exposure to special nuclear material or on a broad geographic scale, mapping out exposure conditions after a catastrophic nuclear event. The goals of the program primarily focus on the correlations of the incident neutron spectrum to isotopic changes within the battery. These changes can be determined by an activation analysis of long-lived radioactive elements created from neutron interactions.


Our Political Points of View was a political solution put forward by Hu Shi and others to solve the problems of China's social situation in early 1920s.This program showed their interpretation of state toolism,as well as the grasp of the development of the western liberalism ideas.Besides,they had no choice but to place the hope of achieving an orderly social politics on the "good guys".


Optimizing the allocation of units into treatment groups can help researchers improve the precision of causal estimators and decrease costs when running factorial experiments. However, existing optimal allocation results typically assume a super-population model and that the outcome data comes from a known family of distributions. Instead, we focus on randomization-based causal inference for the finite-population setting, which does not require model specifications for the data or sampling assumptions. We propose exact theoretical solutions for optimal allocation in $2^K$ factorial experiments under complete randomization with A-, D- and E-optimality criteria. We then extend this work to factorial designs with block randomization. We also derive results for optimal allocations when using cost-based constraints. To connect our theory to practice, we provide convenient integer-constrained programming solutions using a greedy optimization approach to find integer optimal allocation solutions for both complete and block randomization. The proposed methods are demonstrated using two real-life factorial experiments conducted by social scientists.

Falls are a global health issue that especially affects to the elderly. In our previous research, we used a millimeter wave radar to estimate the position of the feet for fall risk assessment of cane users. Radar sensors have a good accuracy, however, due to its low resolution, it is difficult to know if the radar is really tracking the position of the feet or of any other object. In this research, we present a shoe image detector using SSD-MobileNet architecture that could be used in combination with the radar to accurately track the position of the feet. The results show that the proposed detector could correctly recognize the position of the shoes in an image.

The effects of an external shear flow on the dynamics and pattern formation in a dilute suspension of swimming micro-organisms are investigated using a linear stability analysis and three-dimensional numerical simulations, based on the kinetic model previously developed by [D. Saintillan and M. J. Shelley, Phys. Fluids 20, 123304 (2008)]. The external shear flow is found to damp the instabilities that occur in these suspensions by controlling the orientation of the particles. We demonstrate in our simulations that the rate of damping is direction-dependent: it is fastest in the flow direction, but slowest in the direction perpendicular to the shear plane. As a result, transitions from three- to two- to one-dimensional instabilities are observed to occur as shear rate increases, and above a certain shear rate the instabilities altogether disappear. The density patterns and complex flows that arise at long time in the suspensions are also analyzed from the numerical simulations using standard techniques fro...


In the $m_Q\rightarrow\infty$ limit, the hyperfine splittings in the ground state doubly heavy baryons $\left(QQq\right)$ and single heavy antimesons $(\bar{Q}q)$ are related by heavy quark-diquark symmetry (HQDQ) as the light degrees of freedom in both the hadrons are expected to have identical configurations. In this article, working within the framework of nonrelativistic QCD (NRQCD), we study the perturbative and nonperturbative corrections to the HQDQ symmetry hyperfine splitting relation that scale as ${\cal O}\left(\alpha_s^2\right)$ and $\Lambda_{\rm QCD}^2/m_Q^2$ respectively. In the extreme heavy quark limit, the perturbative corrections to hyperfine splitting of doubly charm or bottom baryons are a few percent or smaller. The nonperturbative corrections to hyperfine splitting are of order $10\%$ in the case of doubly charm baryons and $1\%$ or smaller in doubly bottom baryons.

Elagolix is a novel, oral gonadotropin‐releasing hormone receptor antagonist indicated for the management of moderate to severe pain associated with endometriosis and heavy menstrual bleeding associated with uterine fibroids. Consistent with its mechanism of action, elagolix exhibited dose‐dependent suppression of estradiol (E2) in clinical studies. A dose‐response model that describes the relationship between elagolix dosages and average E2 levels was combined with a previously published quantitative systems pharmacology (QSP) model of calcium homeostasis to predict bone mineral density (BMD) changes during and following elagolix treatment. In the QSP model, changes in E2 levels were linked to downstream changes in markers of bone resorption (carboxyterminal cross‐linked telopeptide of type 1 collagen [CTX]), formation (N‐terminal propeptide of type 1 procollagen [P1NP]) and BMD. The BMD, CTX, and P1NP predictions by the QSP model were validated against observed data from four phase III clinical trials of elagolix in premenopausal women with endometriosis. BMD, CTX, and P1NP were successfully described by the QSP model, without any model fitting, suggesting that the model was validated for further predictions of elagolix effects on BMD. Simulations using the validated QSP model demonstrated that elagolix 150 mg once daily dosing for 24 months is predicted to result in −0.91% change from baseline in lumbar spine BMD. The QSP model simulation results were part of the totality of evidence to support the approved duration of therapy for elagolix 150 mg once daily in patients with endometriosis.

Introduction: Self-medication of slimming supplements has increased. The media advertising is involved in this field. The aim of the study was to determine the effect of media literacy educational intervention in the students' self-esteem and body image and their attitudes about self-medication of slimming supplements among the female dormitories in University of Medical Sciences in Iran. Materials and Methods: In this quasi-experimental study of a controlled type, 98 students were selected by multistage cluster sampling method and randomly divided into two groups of 49 test and 49 control. The data collection instruments were the researcher-made questionnaire about media literacy and an attitude of self-medication of slimming pills, BICI questionnaire of body image and SEI Cooper Smith's questionnaire of self-esteem. Based on the results obtained from the questionnaires early completion, an appropriate educational intervention was designed and carried out. One and three months after the intervention, the data gathered and was analyzed in (16) SPSS software using descriptive and analytical tests. Results : Before the intervention, the mean scores of attitude, body image, self-esteem and dimensions of media literacy in both groups were middle, and there was no significant difference between them. Also, positive correlations were observed in the experiment group between attitude and knowledge (r=0.99, p=0.001), critical thinking (r=0.61, p=0.001) and analysis (r=0.37, p=0.009). One and three months after the intervention, the mean scores of  body image, self-esteem, and dimensions of media literacy was observed significantly in the both groups (p<0.05). Conclusion: Media literacy education was effective in promoting the attitude about slimming supplements. DOI: 10.18869/MPHBS.2016.21 Â


In my studies I focused on the writings of St. Francis. St. Francis turn to us asking for compassion resulted from my analysis of his writings. St. Francis encourages us to share compassion with the others and the whole creation. He directed his message most of all to those of us who share the same feelings for faith. The faith which he was granted from God St. Francis wrote down in his Rule which was subsequently endorsed by the Catholic Church. My paper consists of four parts: The image of man in St. Francis` writings, The meeting of the leper, The sick, the poor, the abandoned, the enemies, His attitude to the whole God`s creatures. His inspiration for love St. Francis drew from his personal experience of God`s love. He believed that human dignity was bestowed by god himself. Man was created by God and modeled on His own image, argued St. Francis therefore man testifies to God`s presence in the world. St. Francis` compassion originated from poor and humble Jesus Christ. St. Francis' compassion with the poor, sick, suffering, despised, sinners and enemies draws inspiration from the same spiritual source.


This paper deals with the study of the quasilinear critical problem − p pu + V (z)up−1 = f (u) + up−1 in R, u ∈ C loc(RN) ∩ W1,p(RN), u > 0 in R, (P ) where is a small positive parameter; f is a subcritical nonlinearity; p∗ =pN/(N −p), 1< p < N , is the critical Sobolev exponent; and V : R → R is a function which is bounded from below away from zero such that inf V > inf V for some open bounded subset of R . We study whether we can find solutions of(P ) which concentrate around a local minima of V , not necessarily nondegenerate. The proof of this result is variational based on the local mountain-pass theorem. 2005 Elsevier Ltd. All rights reserved. MSC:35J60; 35B25; secondary 35Q55; 58E05


With the steady increase of computing power, it will soon become conceivable to decode the function of an enzyme strictly from its molecular structure. To realize this ambitious goal, progress has to be made on two fronts: (1) the realism of the molecular models used in the simulations and (2) the speed at which these models can be computed. The author discuss aspects of these two problems with work on zinc enzymes and on ammonium transport proteins.


Extremely narrow and bulk-like p-type InAs-Si nanowire TFETs are studied using a full-band and atomistic quantum transport simulator based on the sp3d5s* tight-binding model and a drift-diffusion TCAD tool. As third option, the WKB approximation has been adapted to work in heterostructures through a careful choice of the imaginary dispersion. It is found that for ultra-scaled InAs-Si nanowire TFETs, the WKB approximation and the quantum transport results agree very well, suggesting that the former could be applied to larger hetero-TFET structures and considerably reduce the simulation time while keeping a high accuracy.

Summary Glucose utilization and lactate production have been measured in suspensions of leucocytes in plasma from normal human subjects and from patients with diabetes mellitus. The rate of glucose utilization was significantly lower in leucocytes from severe diabetics than in leucocytes from normal human subjects. Lactate production did not differ significantly between normal and diabetic subjects. In more than three-fourths of the experiments on diabetics and about one-half the experiments on normal subjects, glucose utilization by leucocytes was increased by insulin in vitro.Lactate production was not increased when insulin was added in vitro.


The aim of this study was to determine the temperature field distribution and variation law of the thermoelectric efficiency of annular thermoelectric generators. To find those factors, we established thermoelectric equation in a cylindrical coordinate system. This paper shows that the maximum thermoelectric efficiency of a thermoelectric device is independent of its geometry but is dependent on its material parameters and boundary temperature. Given a certain current density, if the temperature difference changes, for example, if the temperature at the hot end rises, in structures of the same inner diameter, as the thickness increases, the thermoelectric efficiency first decreases and then increases. This theoretical analysis could provide guidance for designing cylindrical thermoelectric generators.

We thank the editorial board for the opportunity to engage in a public dialogue about our work and the commentators for providing interesting and challenging comments. We are especially pleased that Tom Snijders and Carter Butts took the time to comment on our article because the Dynamic Network Actor Model (DyNAM) builds upon both their work. Moreover, their contrasting comments highlight important distinctions between actor-oriented and tie-based network models as well as in methodological thinking more generally. We take this opportunity to clarify some misconceptions and further develop a lively discussion within our research community. First, we identify what we perceive as different ideas about the aim of statistical network modeling. Second, we outline our conclusions about the fundamental difference between actorand tie-oriented models for relational events. Third, we respond to specific comments received by Carter Butts (Butts, 2017) and Tom Snijders (Snijders, ∗Corresponding author: Christoph Stadtfeld, ETH Zürich, Chair of Social Networks, Department of Humanities, Social and Political Sciences, Clausiusstrasse 50, 8092 Zürich, Switzerland, phone: +41 44 632 07 93, e-mail: firstname.lastname@example.com

The monitoring of passenger flow congestion in subway stations is the key to passenger flow analysis and safety control of rail transit. For the problem of passenger flow monitoring in subway station, a real-time monitoring method of passenger flow congestion based on surveillance video is proposed in this paper. Considering the characteristics of high density and serious occlusion of passenger flow in subway stations, this paper constructs a real-time monitoring model of passenger congestion in subway stations based on improved YOLOv3 is built. Firstly, YOLOv3 algorithm is modified as follows: CIoU is introduced instead of IoU to calculate the regression loss function of the target bounding box, which improves the positioning accuracy of the target bounding box; the Focal Loss function is added to guide the model to focus on the training of hard-to-class samples with high occlusion; the K-means clustering algorithm is introduced to re-cluster on the self-made dataset to obtain the anchor boxes suitable for subway station passenger flow. Then the congestion level of different areas in subway stations is divided, and the method of passenger flow congestion identification is given. Finally, an experiment is carried out based on the self-made subway pedestrian dataset SOP. The experimental results show that the average accuracy of this method increases from 92.11 % to 94.45 %, the average detection speed increases from 28.634 fps to 29.681 fps compared to former algorithm, which can meet the requirements of real-time and accuracy of pedestrian detection in subway stations.

The dynamic characteristics of species composition and species diversity of meadow grassland in Keerqin Sandy Land in the last 20 years were studied.The results showed that the meadow vegetation in Keerqin Sandy Land has seriously degraded.Species diversity and evenness of community has decreased and ecological dominance increased.The quality and production of herbaceous plants in general has declined.The quantity and dominance of fine herbaceous species decreased while that of poor quality and of poisonous grass species increased.The reasons for this grassland degradation included: warming and drying of the local climate,habitat drying,soil salinization and over grazing.Over grazing was the main and direct reason for degradation of the meadow vegetation.The influence of over grazing on species composition,biomass,diversity and nutrient content in of the main communities were also analyzed.


There has been recent interest, and significant success, in adapting and extending ideas from statistical learning via Gaussian process (GP) regression to optimization via simulation (OvS) problems. At the heart of all such methods is a GP representing knowledge about the objective function whose conditional distribution is updated as more of the feasible region is explored. Calculating the conditional distribution requires inverting a large, dense covariance matrix, and this is the primary bottleneck for applying GP learning to large-scale OvS problems. If the GP is a Gaussian Markov Random Field (GMRF), then the precision matrix (inverse of the covariance matrix) can be constructed to be sparse. In this paper we show how to exploit this sparse-matrix structure to extend the reach of OvS based on GMRF learning for discrete-decision-variable problems.


Iron minerals in soil play an important role in controlling the migration of fluoroquinolones. In this study, batch experiments were carried out to investigate interactions in ciprofloxacin (CIP) adsorption to goethite, hematite and magnetite at pH 6.0. Thermodynamics and the site energy distribution theory (SEDT) were adopted to clarify the complexation types. According to the adsorption results, the pH-dependent interactions were qualitatively elucidated. The thermodynamic data implied the difference in adsorption mechanisms. With increasing sorbate loading, CIP adsorption to hematite and magnetite was endothermic and both enthalpy change (∆H) and entropy change (∆S) decreased; but CIP sorption to goethite showed totally opposite characteristics. The higher adsorption capacity and affinity of CIP to hematite and magnetite than those to goethite were caused by their higher site energy of the highest occurring frequency (E0 * ) and the temperature-dependent average site energy (Em ), respectively. The E0 * on the surface of goethite was about 17 ∼ 19 kJ/mol, while those of hematite and magnetite were in the range of 20 ∼ 26 kJ/mol. When temperature increased from 289.15 K to 308.15 K, the high- and low-energy site densities for three iron minerals changed by -32% to 167% and by -36% to 223%, respectively. The different thermodynamic and SEDT results indicated that CIP adsorption mechanisms to goethite and hematite/magnetite were mainly outer- and inner-sphere complexation, respectively. The findings of this study are helpful to reveal the adsorption mechanisms and evaluate the transport of antibiotics in soils containing typical iron minerals. This article is protected by copyright.

A social opinion process is simulated by logistic equations whose controll parameter is determined by interactions among constituents. The indivisuals take three different opinions (i.e., support, nonsupport, and neutral) in each time and they are updated according to the logistic equations in chaotic regions. The behavior of the change of the total opinion of society and distribution of it are investigated. We quantify the complexity of the opinion evolution against a social atmosphere by applying a statistical complexity measure. Key-Words:Social opinion formation, Chaos, Complexity


Abstract During the late 1980s and early 1990s white supremacist vigilantes attacked Native American spear fishers attempting to exercise treaty rights in northern Wisconsin. Nearly a decade later, Native Americans organized a coalition that included some of their former white supremacist enemies to stop plans by transnational corporations to pursue environmentally harmful resource exploitation enterprises in the region. Native Americans and their allies had to respond to corporate promoted 'new right' white identities to defend themselves in the spearfishing struggle by creating new counter-hegemonic racial identities for their enemies and themselves. Their experiences show how regressive and progressive racial identities become formed through struggle and how struggles over racial identities can help generate a broader movement for social justice.


Scientific hermeneutics thinks that Science has its premise, understanding of Science has its "hermeneutic circle" .Science is a form of people's living, is a practice of existence. Science doesn't exist in vacuum of mankind without hermeneutics. Science isn't a purified system of formula. It must exist in society, culture and politics of mankind "co-exist". The whole understanding to scientific hermeneutics can not leave tri-dimensions of ssk, micro-politics studies of science and micro-culture studies of science.
