We investigated the temperature dependency of photosynthetic rates for five Sphagnum species: Sphagnum palustre, S. fimbriatum in the Tadewara mire (south-western Japan in a warm-temperate zone) and S. papillosum, S. fuscum, S. fallax in the East Ochiishi mire (north-eastern Japan in a cool-temperate zone) measuring photosynthetic light response within a temperature range between 5 and 40。C. The maximum photosynthetic rate was obtained at T = 35。C for S. palustre, S. fuscum and S. papillosum, and at T = 30。C for S. fimbriatum and S. fallax. Photosynthetic rates of all these species showed a maximum at 300 - 500 μmol·m-2·s-1 of PPFD and it decreased at higher PPFD (>500 μmol·m-2·s-1) under low temperature (5。C - 10。C). These results imply that Sphagnum species are not fully physiologically adapted to low temperature environments, although Sphagnum species distribute mostly in the circumpolar region.


Additive for ready mixed mortar can be obtained better performance,so it has been widely adopted in practice,but it also has some problems.Effects of retarding high range water reducing agent,thickening and water retention components,retarding components and saled in the market special additive for ready-mixed mortar on performance of mortar were studied respectively.Testing results showed that the additive was good for water retention of mortar,excellent workability,strength was also influenced significantly by mixing amount of additive,the mixing amount of additive must be strictly controlled.


Thermoacoustic engine is an energy conversion device that uses the energy carrying capacity of sound waves to generate sound power from thermal energy. Although it is not difficult to build thermoacoustic engines due to having no moving parts, many researchers have always tried to reduce the temperature difference required to run thermoacoustic engines, so that these devices can be used in most industries. To investigate the onset conditions of the system, temperature changes in the stack section of a standing wave Thermoacoustic engine were investigated. Numerical analysis of temperature changes along the stack, was performed using the Rott's thermoacoustic equations. The temperature was calculated instantaneously along the stack, and this process continued until the thermal equilibrium was established in the system. In addition, integrating numerical solution equations with the circuit analogy method, made it possible to calculate the startup time of spontaneous oscillations. A standing wave with an open end was designed and built to validate the temperature curves obtained at different moments. This thermoacoustic engine was able to display the temperature instantaneously along the stack with parallel plates structure. The data obtained from the experimental tests and the temperature changes diagram resulting from the numerical solution method, showed a good agreement with each other for the onset process in the system. Analysis of the Onset Process of Spontaneous Oscillations in a Standing Wave Thermoacoustic Engine, Using the Experimental Method and an Improved Numerical Solution Method.


With the introduction of the Federal Motor Vehicle Safety Standards (FMVSS) 208 Final Rule, the requirements for occupant protection systems in frontal crashes have significantly increased. Especially the requirements regarding the airbag aggressiveness for "Low Risk Deployment" pose new challenges for both automobile manufacturers and suppliers. The testing procedure detailed in § S26 of the FMVSS 208 is commonly referred to as "Out-of-Position" (OoP). This procedure considers the HIII 5% dummy on the driver side for two different positions (position 1: "Chin on Module", position 2: "Chin on Rim"). With the applied testing method, the test setup allows tolerances regarding the dummy positioning relative to the vehicle environment. A comprehensive analysis of the influence of the dummy positioning has shown that particularly the head angle can vary among dummy manufacturers and may result in different OoP load characteristics. Beside In addition to tolerances caused by the airbag module and the steering wheel design itself, the dummy's head angle is a significant factor for a variation of the OoP test results. Out-of-position tests with identical module design have shown that the dummy positioning resulting from the head angle can lead to a misinterpretation of the test results. Depending on the dummy position, the OoP results range from far below the legal limits to a value exceeding them. During the module development process, this scope of interpretations dramatically affects the assessment of the OoP performance and may lead to wrong conclusions.


Abstract The present study evaluated the clinical potential of magnetic resonance (MR) diffusion-weighted imaging (DWI) in the diagnosis of rectal cancer. A total of 84 patients confirmed with rectal cancer were used as study subjects in the present study. All patients received conventional sequence MR T1WI, T2WI, and DWI examination as well as operative pathological examination. The differences between the MRI results and operative pathological results were analyzed. The diagnosis accordance rates of conventional sequence examination in stage T1, T2, T3, and T4 were 60.00%, 82.75%, 62.85%, and 80.00%, respectively. The diagnosis accordance rates of conventional sequence combined with DWI examination in stages T1, T2, T3, and T4 were 100.00%, 100.00%, 82.85%, and 100.00% respectively. The total diagnosis accordance rates in the T staging of rectal cancer with conventional (Routinely or generally applied) sequence examination and conventional sequence combined with DWI examination were 71.42% and 92.85%, respectively. The analysis on consistency of MR conventional sequence examination suggested that the conventional sequence combined with DWI examination is more consistent with pathological staging when compared with the convention sequence examination alone. MR DWI combined with conventional sequences reveals quite good accuracy in the T staging of rectal cancer.


To the Editor, I note with interest the changes that are taking place regarding containment testing of biosafety cabinets under Australian Standard 1807. The new containment test using the potassium iodide ('KI') test method follows that specified in British Standard BS 5726 (1992), which has now been incorporated into a new European Standard, BS EN 12469 (2000), leading to the partial withdrawal of BS 5672 (1992). The 'KI' test has now been in general use in the UK and elsewhere for many years and besides qualifying 'type test' performance for new cabinets, routinely identifies those with poor performance when they are out of specification or where adverse laboratory conditions exist. Users of Australian Standard 1807 may find it useful to familiarise themselves with some published work on the 'KI' method and its applications that has appeared since the inception of the test in 1981.

Introduction: IMT2020 (5G) networks can significantly improve the performance of previous generation mobile communication systems in terms of improving broadband multiple access (eMBB – enhanced Mobile Broadband) and providing ultra-reliable low-latency communication (ULLRC – Ultra Low Latency Rellable Communication). The purpose of the work is to review and comparative analysis of multiple access technologies for promising mobile communication networks, which are based on OFDM. Result: The general principles of signal generation and processing when using variants of signals with OFDM using various methods of digital filtering of subcarrier frequencies are considered. For those OFDM options where a cyclic prefix may not be used (FBMC, UFMC), the possibility of increasing the information transfer rate is controversial, since the impulse responses of filters, for example, with FBMC, significantly exceed the duration of information signals, which increases intersymbol interference. Practical significance: The analysis of the general principles for constructing devices for generating and processing physical layer signals for OFDM variants with various methods of additional digital filtering of subcarrier frequencies shows that in all cases there is a significant complication of digital algorithms for generating and processing signals with a practical absence or in some cases a small gain (not more than (0.5&0.8) dB in relation to signal/noise) by the magnitude of the error per information bit. Based on the results of computer simulation, it is shown that OFDM technology and its variants do not allow obtaining breakthrough solutions in the field of physical layer signal characteristics for 5G and 6G networks, and alternative options for building group signal structures should be considered.

This paper shows that companies tend to switch auditors when audit opinions are inconsistent with those in the previous period, financial performances are worse, and both stock and option values fall. We find no evidence that, during the switching year, option values and firm performance affect the exercise of executives' stock options, possibly because the exercise of stock options often occurs before switching auditors in order to prevent the SEC from investigating insider trading in the switching year. The changes in holdings of executives' stock options are positively correlated with the degree to which analysts' earnings forecasts deviate from previous periods; the announcements of analysts' earnings forecast errors have no influence on the value of executives' options, since that signaling effect has already reflected on the stock price. Furthermore, accruals are unrelated to the changes in holdings of executive stock options, possibly because investors often have negative beliefs about auditor switches, so executives do not tend to take advantage of this opportunity to manipulate earnings.

 Key words: Auditor switch, analyst forecast, executive stock option, earnings management.


Optokinetic nystagmus was analyzed in ten normal subjects by superimposing a gaze point indicator on the image of moving objects. The foveal pattern of nystagmus was commonly elicited at stimulus velocities below approximately 60°/sec. The retinal pattern was observed at all rates. At low stimulus speeds, rudimentary forms of inadequate adjustment such as the waiting or overshooting forms appeared. These changed to the auxilliary or skipping forms of nystagmus, indicating direct influence of stimulus frequency on inadequate response. At high stimulus speeds, the foveal pattern of nystagmus was changed to an inadequate retinal pattern by the slowing of pursuit or the increasing of the degree of waiting.


Abstract : The U.S. Congress has mandated that all aircraft operating within the National Airspace System, military or civilian, be equipped with ADS-B transponders by the year 2020. The ADS-B aircraft tracking system, part of the Federal Aviation Administration's NextGen overhaul of the Air Transportation System, replaces Radar-based surveillance with a more accurate satellite-based surveillance system. However, the unencrypted nature of ADS-B communication poses an operational security risk to military and law enforcement aircraft conducting sensitive missions. The non-standard format of its message and the legacy communication channels used by its transponders make the ADS-B system unsuitable for traditional encryption mechanisms. FPE, a recent development in cryptography, provides the ability to encrypt arbitrarily formatted data without padding or truncation. Indeed, three new algorithms recommended by the NIST, may be suitable for encryption of ADS-B messages. This research assesses the security and hardware performance characteristics of the FF1, FF2, and FF3 algorithms, in terms of entropy of ciphertext, operational latency and resource utilization when implemented on a Field-Programmable Gate Array. While all of the algorithms inherit the security characteristics of the underlying AES block cipher, they exhibit differences in their performance profiles. Findings demonstrate that a Bump-in-the-Wire FPE cryptographic engine is a suitable solution for retrofitting encryption to ADS-B communication.


THE following cases present ,certain points of resemblance which induce me to publish them together. They, however, are in many respects divergent, and I do not wish to assert that the initial pathological process was the same in each. The first case is remarkable on account of the enormous size to which the growth attained, but its pathology is very obscure. Before proceeding to discuss this, however, it will be necessary to give a full account of the history of the


The paper summarized the evolvement characteristics of typical big city suburb regions based on analyzing the evolvement process of farmland landscape size and spatial pattern in 1980,1995 and 2006.The results showed that,firstly,the size of the farmland landscape presented accelerated diminishing,and the rural residential areas and other low density construction land are the subjects which embezzlement farmland;Secondly,the spatial center of gravity of farmland landscape patches moved from the middle position to the northeast direction,far from the center of the urban agglomeration;Thirdly,based on the region mosaic and the single landscape levels,the landscape pattern presented fragmentation and homogenization simultaneously.With the adjustment of the social economic structure and the regional development direction,the farmland landscape of Shunyi occurred significant change.The farmland landscape lost aesthetic feeling gradually by embezzled and cut by roads and mass disordered building.We should protect and use the farmland landscape of the urban suburban reasonably through exploring the different pattern of the farmland landscape treatment and construct.


Several 3-party-based authentication protocols have been proposed, which are resistant to off-line password guessing attacks. We show that they are not resistant to a new type of attack called "undetectable on-line password guessing attack". The authentication server is not able to notice this kind of attack from the clients' (attacker's) requests, because they don't include enough information about the clients (or attacker). Either freshness or authenticity of these requests is not guaranteed. Thus the authentication server responses and leaks verifiable information for an attacker to verify his guess.

Objective To discuss the clinical value of preoperative dual- source CT angiography in evaluating chronic total occlusive coronary artery disease and in guiding interventional management Methods A total of 300 patients with chronic total occlusive coronary artery disease were enrolled in this study. Both dual- source CT angiography and coronary angiography were performed in all patients. The clinical value in guiding the interventional management was assessed, and the results were compared between different examination methods. Results A total of 340 chronic total occlusion coronary branches were detected in 300 patients with coronary artery disease. With the help of dual- source CT angiography vascular reformation, the length of the diseased segment could be precisely determined, and the recognition rate of calcification was improved(up to 76.5%), which was significantly higher than that determined by coronary angiography(41.2%). A total of 240 coronary arteries in 220 patients were confirmed to be completely obstructed.Interventional treatment was employed and successful result was obtained in 120 lesions(50%). Conclusion The dual- source CT scanning can well display calcified lesions, and 3D reformation of the coronary arteries can be obtained, which is very helpful in scientifically guiding the interventional treatment.

Like many of his contemporaries, Francis Galton believed in a positive relationship between head size and intelligence. Head measurements were included among the "mental tests" in Galton's Anthropometric Laboratory of the mid-1880s, which he believed provided measures of inherited natural ability. His pioneering self-report questionnaires distributed to the scientific members of the Royal Society in 1873, designed to elicit information pertinent to their scientific development, did not fail to ask for "measurement round inside of hat."' When Galton's disciple and friend Karl Pearson used his newly developed correlational techniques in 1901 to compute the r between head size and academic record for 1000 Cambridge graduates at only about +0.10, Galton was astonished. He wrote Pearson, "The non-correlation of ability and size of head continues to puzzle me the more I recall my own measurements and observations of the most eminent men of the day."2 D. W. Forrest's recent biography of Galton embellishes this point, asserting that, "throughout his life, [Galton] retained a belief in the high intelligence of those, like himself, with large heads."3 Stated this way, Galton's belief seems a rather transparent form of self-flattery. The relation of Galton's larger theories to the basic facts of his life might be similarly interpreted. He believed that great mental ability was almost completely determined by heredity, and he devoted many years of his life to promulgating his vision of a eugenic society that would bestow breeding advantages on the highly gifted. (Indeed, the ultimate purpose of the tests in his Anthropometric Laboratory was to identify such highly gifted individuals.) Given Galton's own impressive pedigree (he had eminent ancestors from the Galton, Darwin, and Barclay family lines) and his posthumous reputation as a "genius" (hence the subtitle of Forrest's biography, The Life and Work of a Victorian Genius), it is perhaps natural to assume that his theories were, at least partly, vehicles for self-serving vanity.


Abstract : The threshold wavelength for the photolysis of methyl nitrite isolated in solid argon at 14 deg K has been determined to be near 370 nm. Photolyzed samples show prominent infrared absorptions of H2CO and HNO, which are perturbed by the hydrogen-bonding interaction of these two molecules trapped in adjacent sites. In studies with 122- an 105-nm radiation sources and with concurrent deposition and photolysis, some of the H2CO escapes interaction with HNO. Similar observations result on photolysis of methyl-d3 nitrite. Time dependence studies show that in the early stages of photolysis the trans-CH3ONO absorptions grow at the expense of those of the cis rotamer. The stabilization of H2CO and HNO is consistent with gas-phase observations, which have demonstrated that the primary products of the photodecomposition of both cis- and trans-CH3ONO are CH3O + NO, which can recombine with zero activation energy either to re-form CH3ONO or to form H2CO + HNO. The cage recombination of CH3O and NO to form these same products should predominate in the decomposition of methyl nitrates in other condensed-phase systems. The possible deactivation of electronically excited methyl nitrite into lower electronic states or into excited vibrational levels of the ground electronic state which favor direct decomposition into H2CO + HNO is considered.


This paper suggests that fuzzy rules can be extracted from historical data to construct a rule base,and subsequently be used to formulate a mathematical programming model with fuzzy rule constraints. Sugeno inference arithmetic is recommended to establish fuzzy mapping systems in the context of decision variables,which serve as equality constraints of the mathematical programming. Subsequently,a genetic algorithm combined with fuzzy inference is introduced to solve the corresponding problems. The resulting mathematical programming model with fuzzy rules has been applied in a distillation column steady-state optimization problem,and the effectiveness of the proposed approache has been demonstrated.


Mikhail Tarusin in his contribution to "Real Russia (Stratification of the Contemporary Russian Society)", which should come out in 2006, argues that the analysis of changes in the Russian society and of the history of change is necessary not only to understand the nature of historical processes and to forecast the future of the Russian state and people. He provides the statistical data about the structure of the Russian society in the 19th century and during the Soviet times.


Abstract 4845 Hodgkin lymphoma (HL) represents 10–15% of all types of lymphoma. At present, more than 70% of patients can be cured with current strategies based on chemotherapy with or without radiotherapy. However, one third of the cases finally relapses and needs salvage regimens usually consolidated with high dose chemotherapy and autologous stem cell transplantation. The number of regimens and drugs available are limited and new protocols that increase the efficacy with manageable toxicity are needed. In the present communication we report the results of a retrospective study using the GemOx schema that combines the efficacy of gemcitabine in Hodgkin lymphoma with oxaliplatin, a less toxic and effective platinum-based drug. Patients and methods: Patients were eligible for this retrospective study, according to the following criteria: diagnosis of HL, which relapsed or failed to achieve complete remission after induction treatment. They received GemOx regimen that consisted of gemcitabine 1000mg/m2 and oxaliplatin 100mg/m2 on day 1. Treatment was given every 15 days if feasible or every 21 days. To evaluate response and toxicity Cheson criteria and OMS toxicity scale were used respectively. Results: Between 2003 and 2012, 29 patients with Hodgkin lymphoma were retrospectively included in this study. All patients had recurrent (n=17) or refractory (n=12) disease. Median age was 24 (14–76) years and 50% had an International Prognosis Score (IPS) higher than 2. Patients received a mean of 2.79 previous regimens and 79% more than 1 regimen before GemOx with 48% relapsing after a prior autologous stem cell transplant (ASCT). Median follow-up was 41 months. 76% of patients responded (31% complete responses; CR). Responses were better in the relapsed setting or partial response (PR) (85% with a 45% of CR) compared to the truly refractory cases (55% PR) (p=0.037). Main prognostic factors for HL were assessed to view their impact on survival. Factors related with progression- free survival (PFS) and overall survival (OS) were age lower than 45 years, response to GemOx and consolidation with stem cell transplantation (p=0.001). Presence of B-symptoms at diagnosis also influenced OS. Neurologic toxicity was present in 9% of patients, all of them grade I or II. Hematologic toxicity was also common, including grade 3 or 4 neutropenia in 23% of patients, and grade 3 or 4 thrombocytopenia in 33%. Nausea and vomiting occurred in all the patients at grade 2, or lower. At last follow-up, 13 patients (45%) are alive and remain free of progression. However, 16 patients (54%) had died: 12 (41%) due to progression of disease, 3 (10%) due to complications due to a subsequent allogenic transplant (graft versus host disease, thrombotic thrombocytopenic purpura and bleeding) and 1 due to pneumonia. PFS was better in patients consolidated with autologous or allogeneic transplantation (100%) compared with patients not consolidated (14%) (p=0.009). PBSC collection after GemOx and G-CSF was successful for all of candidates. Conclusions: 1) GemOx regimen is effective in relapsed or refractory Hodgkin lymphoma with manageable toxicity; 2) Results are better in relapsed or chemosensitive disease compared to truly refractory cases; 3) No mobilization failures were observed; 4) Consolidation after response is needed. Disclosures: No relevant conflicts of interest to declare.

 High-density lipoprotein (HDL) particles have been shown to undergo adverse remodelling and loss of function in the presence of comorbidities. It has been demonstrated that high low-density lipoprotein cholesterol (LDL-C) plasma levels induce compositional changes in HDL particles that render them dysfunctional. It is unknown, however, whether this HDL adverse remodelling is reversible.

 In this preclinical animal study we have investigated whether dyslipidaemia-induced HDL particle remodelling and dysfunction is a permanent adverse change or a temporal trait which can be regulated by dietary intervention.

 After 10 days of high-fat diet (HFD) and reaching LDL-C levels of 392.8±94.9 mg/dL, the HDL particles of 15 pigs were characterized. Thereafter, pigs were randomly distributed into two arms. While group 1 was maintained on the same HFD (n=9), group 2 was switched to a normocholesterolemic diet (NCD; n=8) up to day 40. Blood was drawn at days 0 (baseline), 1, 3, 5, and 10 (to characterize HDL dysfunction over the 10-day period of dyslipidaemia induction), and at days 25 and 40 (to assess the HDL particle evolution in the intervention period). We assessed: a) HDL function [cholesterol efflux capacity (CEC) and antioxidant potential]; b) HDL particle number and size by nuclear magnetic resonance; c) oxidative susceptibility of LDL particles; d) HDL protein content of APOA-I, APOM, and APOC-III; and e) biochemical parameters.

 Up to day 10 there was a time-dependent increase in LDL-C levels that progressively induced the impairment of HDL CEC and antioxidant activity, higher HDL particle numbers, increased formation of conjugated dienes, and lower HDL-APOM content (p<0.01 vs baseline). All these parameters exhibited a plateau at day 10 and remained unchanged up to day 40 in those animals that were kept on HFD. Interestingly, in these animals a strong negative correlation was observed between HDL CEC and HDL-C levels (p<0.0001), with larger HDL particles being detected at day 40 (p<0.05 vs. baseline). On the contrary, all these parameters returned to physiological levels (baseline) in those animals that switched to a NCD (p=ns vs baseline). No changes were detected in APOA-I- and APOC-III- HDL content among animal groups and over time.

 In the present study we evidence for the first time that dyslipidaemia-induced HDL particle remodelling and dysfunction is not a permanent adverse change. The implementation of a healthy dietary intervention acutely reverses HDL adverse remodelling and dysfunction in a preclinical animal model.


The analysis of drill-core samples is one of the most important steps in the mining industry for the exploration and discovery of mineral resources. Geochemical assays are a common approach to represent the abundance of different chemical elements and aid at quantifying the concentrations of the important ore accumulations. However, their acquisition is time-consuming and usually averages of long core portions. Hyperspectral data are increasingly being used in the mining industry to complement the analysis of drill-cores due to their efficiency and fast turn-around time. Moreover, hyperspectral imaging is a technique able to provide data with high spatial resolution. In this article, we propose to integrate the complementary information derived from hyperspectral and geochemical data via a superpixel-based machine learning framework. This framework considers the difference in spatial resolution through segmentation. We extract labels from the geochemical assays and select, from the hyperspectral data, representative samples for each measurement. A supervised machine learning classification (composite kernel support vector machine) is then used to extrapolate the elements relative abundance to the entire core length. We propose an innovative integration of hyperspectral data covering different regions of the electromagnetic spectrum in a kernel-based framework to facilitate the identification of a larger amount of elements. A qualitative and quantitative evaluation of the results demonstrates the capabilities of the proposed method, which provides approximately 20% more accurate results than the pixel-based approach. Results also imply that the method could be beneficial for the reduction of geochemical assays needed for the detailed analysis of the cores.


The role and place of women in the world cannot be underestimated. In governance, politics, military, commerce, industry, high-tech, agriculture. Imagine a world without Angela Markel; Hilary Clinton; Margaret Thatcher; Indira Gandhi; Mrs Gates; Mrs Zuckerberg and all the Whos Who in World Women. In agriculture, they are the bedrock from ancient times. As men go for hunting expedition, the women engage in gathering and nurture of natural resources to put food on the family's table. Even before the US launching of "Cooperative Extension" in 1914 and the UN World Conference on Women in 1995 there is no denying the fact that women were relegated to the background by men in all realms of life. Thanks to many women liberation movements that have identified and liberated women especially in developed countries. Today, women are nearly ruling the world. In agriculture, they have been identified as pillars for sustainable development and livelihood. Hence, our agricultural extension services must put women as the insurance for averting world food catastrophes as world population leap in bounds. Currently at over 6 billion and projected to reach 9 billion in 2050.


Long Term Evolution (LTE) is a standard for wireless communication of high speed data for mobile phones and data terminals. LTE is capable of delivering large data rate on the order of several megabits per second, which is even larger than the current 3G systems. This is very challenging as the wireless networks are subjected to interference, multipath and poor propagation channel characteristics that limit data rates. Multiple-Input Multiple-Output (MIMO) in LTE enables radio systems to achieve significant performance gains by using multiple antennas at the Transmitter and Receiver, thereby leveraging the spatial dimension. When the signals are combined properly at the receiver, the signal quality or data rate for each MIMO user will be improved. This paper provides simulation data to show the performance of different MIMO transmission modes in an LTE system, so that in the future we could develop an adaptation algorithm which would result in better performance.


Abstract. Previous studies have found that different trajectories of conflicted relationships with teachers predicted academic underachievement. However, little is known about what places children at risk of atypical conflict trajectories. This follow-up study examines whether African American ethnicity, IQ, and socioeconomic status (SES) are unique predictors of teacher–student conflict trajectories, taking into account sociobehavioral predictors, including aggression and prosocial behavior. The study included an ethnically diverse sample of 657 academically at-risk children in which four latent growth classes of conflict trajectories (Grades 1–5) predicted underachievement previously. In this follow-up study, six predictors were examined: African American ethnicity, SES, IQ (independent assessment), inhibitory control (performance measure), and aggression and prosocial behavior (peer assessment). The results showed that African American ethnicity, but not IQ and SES, uniquely predicted atypical conflict trajectories while controlling for sociobehavioral predictors. African American children were at risk of increasingly conflicted relationships with elementary school teachers, which has been found to increase the risk of academic underachievement in middle school.


Detecting manipulated facial images and videos on social networks has been an urgent problem to be solved. The compression of videos on social media has destroyed some pixel details that could be used to detect forgeries. Hence, it is crucial to detect manipulated faces in videos of different quality. We propose a new multi-stream network architecture named GGViT, which utilizes global information to improve the generalization of the model. The embedding of the whole face extracted by ViT will guide each stream network. Through a large number of experiments, we have proved that our proposed model achieves state-of-the-art classification accuracy on FF++ dataset, and has been greatly improved on scenarios of different compression rates. The accuracy of Raw/C23, Raw/C40 and C23/C40 was increased by 24.34%, 15.08% and 10.14% respectively.


In newborns, high signal intensity in the subthalamic nuclei may be indicative of cerebral ischemia, particularly in combination with high signal in the posterior putamen. This article describes transient and normal high signal intensity in the subthalamic nuclei and globi pallidus. Seventy-nine neonates who had normal examinations 2 years later were included in the study. The authors performed qualitative and quantitative evaluations of these 2 regions on T1- and T2-weighted images and correlated their results with postnatal and gestational ages. With increasing postnatal age at examination, the high signal intensity on the T1-weighted images for both subthalamic and globi pallidus diminished. Although the disappearance of this hyperintensity was well correlated with the postnatal age at examination for both the qualitative and quantitative studies, there was no correlation with gestational age at examination. For the T2 images, there was no correlation with either the postnatal age or gestational age at examination. BACKGROUND AND PURPOSE: In the brains of newborns, changes in signal intensity in most structures can be explained by the development of myelination. However, there are some structures for which signal intensity changes cannot be accounted for by myelination alone. We examined the STN and globus pallidus signal intensities and tried to determine whether a relationship exists between the signal intensity and the postnatal age or the gestational age at the examination. MATERIALS AND METHODS: We examined T1WI and T2WI obtained from 79 neonates who showed normal development at their 2-year follow-up examinations. We performed both qualitative and quantitative (signal intensity ratio to the thalamus) evaluation of the STN and globus pallidus signals, and we examined the correlation between signal intensity changes and the age of neonates. RESULTS: With increasing postnatal age at examination, the high signal intensity on the T1WI for both STN and globus pallidus diminished. Although the disappearance of this hyperintensity was well correlated with the postnatal age at examination for both the qualitative and quantitative studies, there was no correlation with gestational age at examination. For the T2WI, there was no correlation with either the postnatal age or the gestational age at examination. CONCLUSIONS: Signal intensity on T1WI in the STN and globus pallidus is not related to the gestational age at examination; instead, signal intensities on T1WI seem to be more dependent upon the postnatal age at examination.


Abstract : We present high resolution x-ray spectra taken during a large solar flare on 10 June 1979. Many lines of highly ionized iron are resolved and identified for the first time in solar spectra. Lines with a wide range of excitation temperatures are found to have a similar time development during the flare's rapid rise phase. We discuss density-sensitive line ratios in Fe XXI and Fe XXII.

Minimum cycle base of a graph which is the join of two disjoint graphs is discussed according to two cases,and the corresponding formula for length of minimum cycle base of each case is given.As applications of two formulae,it gives formulae for lengths of minimum cycle bases of some special graphs,such as the graph which is the join n isomorphic graphs and the complete r-partite graph,etc.


Synthesis of 2-amino-6-chloropyridine by the reduction of 2-hydrazino-6-chloropyridine under various conditions is described. The way through 2-azido-6-chloropyridine and its reduction afforded the pure product, but it is laborious. The best results were achieved by the reduction with hydrazine and Ra/Ni catalysis. The method usually used – reduction with hydrogen – afforded the product containing large amount of dehalogenated by-product.


[1] Impact of climate change on streamflow in the Upper Mississippi River Basin is evaluated by use of a regional climate model (RCM) coupled with a hydrologic model, Soil and Water Assessment Tool (SWAT). The RCM we used resolves, at least partially, some fine-scale dynamical processes that are important contributors to precipitation in this region and that are not well simulated by global models. The SWAT model was calibrated and validated against measured streamflow data using observed weather data and inputs from the U.S. Environmental Protection Agency Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) geographic information systems/ database system. Combined performance of SWAT and RCM was examined using observed weather data as lateral boundary conditions in the RCM. The SWAT and RCM performed well, especially on an annual basis. Potential impacts of climate change on water yield and other hydrologic budget components were then quantified by driving SWAT with current and future scenario climates. Twenty-one percent increase in future precipitation simulated by the RCM produced 18% increase in snowfall, 51% increase in surface runoff, and 43% increase in groundwater recharge, resulting in 50% net increase in total water yield in the Upper Mississippi River Basin on an annual basis. Uncertainty analysis showed that the simulated change in streamflow substantially exceeded model biases of the combined modeling system (with largest bias of 18%). While this does not necessarily give us high confidence in the actual climate change that will occur, it does demonstrate that the climate change ''signal''stands out from the climate modeling (global plus regional) and impact assessment modeling (SWAT) ''noise.''

A novel reentrant cavity-microstrip patch antenna integrated wireless passive pressure sensor was proposed in this paper for high temperature applications. The reentrant cavity was analyzed from aspects of distributed model and equivalent lumped circuit model, on the basis of which an optimal sensor structure integrated with a rectangular microstrip patch antenna was proposed to better transmit/receive wireless signals. In this paper, the proposed sensor was fabricated with high temperature resistant alumina ceramic and silver metalization with weld sealing, and it was measured in a hermetic metal tank with nitrogen pressure loading. It was verified that the sensor was highly sensitive, keeping stable performance up to 300 kPa with an average sensitivity of 981.8 kHz/kPa at temperature 25°C, while, for high temperature measurement, the sensor can operate properly under pressure of 60–120 kPa in the temperature range of 25–300°C with maximum pressure sensitivity of 179.2 kHz/kPa. In practical application, the proposed sensor is used in a method called table lookup with a maximum error of 5.78%.


In this study, two methods to evaluate the disassemblability of the parts are proposed, which are constructed from the concepts of ease-of-disassembly and disassembly time. A method to evaluate the disassemblability of the products is consequently developed using the concept of minimum parts. The methods are applied to evaluate the disassemblability of computer cases. The results show the conclusions that the new model has less disassemblability than the old one. These methods are expected to be used for the evaluation of the possibility of remanufacturing and recycling of a part.


When a given plant has poles on the jω axis in the two block mixed sensitivity problem setting, they become the zeros of G12 or G21 in the generalized plant, and the H∞ control problem becomes a nonstandard one. To circumvent this problem on zeros, the authors introduce a loop transforming technique and the extended H∞ control theory, previously proposed by authors, and derive an H∞ controller. The results include a design method of a servo system where the poles of the plant or/and the designed controller play a role of the internal model. This particularly is useful in designing motion control systems because one often models actuators to have single or double integlators when the damping coefficient and/or the spring coefficient are small but uncertain.


Determination of the CH 4 flux from the reed wetland of Liaohe delta, China using closed chamber technique showed that the emission of CH 4 from the reed wetland had a significant seasonal variation. Before irrigation, wetland soil absorbed CH 4.Higher emission rate of CH 4 occured durin the flooding period. And after drainage, CH 4 emission decreased significantly. CH 4 flux from reed wetland ecological system during the period of measurement was -968~2734μgCH 4/(m 2·h). In addition, CH 4 released into atmosphere was mainly through the transportion of reed plant. The experimental result also showed that CH 4 emission from the wetland dominated with reeds was fifteen times greater than that without reeds. We suggest that the reed field should be flooded by intermittent management, which improves both growth of reeds and mitigates emission of CH 4.


Although agricultural land abandonment (LA) is accompanied by land degradation, it could be considered a kind of self-rehabilitation. Studies have shown that long-term LA has profound ecological and environmental benefits, whereas few studies have compared LA with human intervention (HI), which involves planting and fertilization in agroecosystem restoration. Here, we established four different scenarios based on local livestock husbandry, including LA without HI, LA with slight human intervention (HIS), medium human intervention (HIM), and intensive human intervention (HII). LA experiments were conducted for 3 years and repeatedly sampled three times. The soil bacterial and fungal communities were determined to present the ecological impacts. In this study, LA and HIS could save soil inorganic carbon and total calcium (Ca) contents and benefit soil mycorrhizal fungi and plant growth-promoting rhizobacteria. LA and HIM benefited some microbial communities associated with complicated organic compounds. Human interference methods did not significantly increase soil nutrients after 3 years of farmland abandonment. However, indigenous vegetation increased the risk of plant diseases based on soil microbial communities. Forage grass may control the risk, and HIS was a cost-effective scenario in our study. Moreover, we should maintain a cautious attitude toward HII to prevent excessive intervention.


The presence of hydrogen sulfide (H2S) determines the air quality of both indoor and outdoor environments. To measure H2S concentration levels in the environment, a variety of sensors have been developed. metal oxide (MO x ) based gas sensors are among the most interesting class of MEMS sensors, capable of producing highly sensitive, selective, and specific signals in a plethora of chemical and physical signals. Nonetheless, in the presence of moisture, they have poor selectivity and response. However, the sensing performance of MO x towards H2S gas is previously reported in a number of studies. Nanotechnology advancements are expected to lead to the progress of highly sensitive, stable, and selective MO x -based H2S gas sensors in the future. This review article aims at enlightening the various aspects of H2S gas sensing technology in an unpretentious yet comprehensive manner.


Objective: To evaluate the effectiveness of a patient-specific
immobilization and positioning device in prostate radiotherapy. Methods: Eighty
patients were immobilized and positioned by a patient-specific device. Prostate
translations and rotations were estimated from daily cone beam computed
tomography scans using a contour-based approach assisted by auto-registration
and quantified by the group mean GM, systematic Σ and random σ' errors. Dosimetric impacts of
residual prostate rotations where the translation errors were corrected were
evaluated by robustness plan analysis. Results: Using the patient-specific
immobilization alone without online image-guidance, the GM, Σ and σ' of the prostate translations were
0.8, 1.7, and 1.5 mm (left-right; LR), 0.8, 2.1, and 1.9 mm (superior-inferior;
SI), and 0.5, 1.7 and 1.5 mm (anterior-posterior; AP), while for the prostate
rotations they were 0.0°, 0.6°, and 0.7° (pitch), 0.2°, 0.5°, and 0.6° (roll), and 0.2°, 0.5°, and 0.6° (yaw). The resulting
van Herk's margin was 5.8 (LR), 7.3 (SI) and 5.8 (AP) mm. With adaptive online
image-guidance based on estimates from the first 5 fractions, Σ were reduced by
0.7 - 1.2 mm for the prostate translations, resulting in a margin reduction by
2 - 3.5 mm. Changes of Σ and σ' in
the prostate rotations were insignificant regardless of translation
corrections. Dosimetric impacts of residual rotation errors were negligible if
a 2 mm margin was applied. Conclusions: Our patient-specific immobilization system can effectively
limit the prostate translations and rotations, which is important without 6D
treatment couches or using ultrasound image-guidance without rotational
corrections.


ABSTRACT Procedural differences between civil justice and redress schemes are well known, but knowledge gaps stymie an ability to compare monetary outcomes. This paper advances the field of institutional abuse of children by analysing outcomes for 4563 civil justice and redress scheme claims of sexual abuse of children received by 36 Australian Catholic Church authorities (CCAs) over 35 years. The authorities are archdioceses, dioceses and male and female religious institutes. As expected, average civil justice payments are higher than those for redress schemes. However, there is huge payment variation and a good deal of overlap between the two, especially at the lower end of the payment spectrum. We explain payment variation by a generally lower, average or higher paying orientation of the CCAs, coupled with a strong lower paying orientation of the female religious institutes. Victims and survivors of institutional child abuse require information on outcomes of civil justice and redress scheme claims, rather than the siren song of large civil payments. We join others in calling upon all relevant actors to 'show the data' on settled claims.


Cross ratio is an essential invariant with respect to projective transformations.To discover intrinsic properties of a scene by using the computation of cross ratio invariance has been one of the most hot research areas in computer vision fields.The computation by using image coordinates will cause computational breakdown or deterioration of accuracy,and the computation by using homogeneous coordinates will increase computation.The N-vector formalism for computing cross ratio is proposed from the perspective of computational processes in this paper if a point and a line on the image plane are represented in terms of N-vectors.One application of the formalism on the basis of study is presented: The procedures for computing collineation matrix that maps four arbitrarily given image points in general position to four arbitrarily given image points in general position based on projective invariance of cross ratio are constructed.The result of example shows that this algorithm is more utility and reliable than traditional algorithms.


The use of local ingredients in poultry diets is a key strategy to mitigate the high cost of commercial feed and improve profitability of small-scale farming. The aim of the study was to assess the growth performance and production costs of broilers fed a diet of milled cassava blended with a locally formulated protein concentrate. The test diet was compared against the commercially available broiler finisher feeds presented as pellets and milled crumble. The three diets were replicated four times with fifteen birds per replicate using a completely randomised design. Broiler chickens (N=180) at 21 days were randomly allocated in 12 pens and the weekly body weights, body weight gains, in-takes, feed conversion ratio and production costs based on feed consumed were recorded. The live body weights of birds on the three diets were similar at days 28, 35 and 42. At day 28, feed intake of birds fed the commercial diets as pellets and milled crumble were higher (P<0.05) than that for birds fed the test diet. All feed intakes were similar after day 35. Birds on test diet performed better (P<0.05) in terms of body weight gain and feed conversion at day 28. However, body weight gain and feed conversion did not differ at days 35 and 42. The overall production cost for birds on test diet was 2.3 % higher than the commercial diet. However, the feed cost for test diet was 11 % lower compared to the commercial diet, suggesting that protein concentrate blended with cassava is cheaper to purchase. Further studies are recommended to assess different inclusion levels of cassava root meals as well as other local ingredients with the protein concentrate.


In this work, we report the phase diagram of lead-free ternary (1 - y)[(1 - x)(Bi0.5Na0.5) TiO3-x (Bi0.5K0.5)TiO3]-y(K0.5Na0.5)NbO3 (BNT-BKT-KNN) system and study the switching characteristics of the morphotropic phase boundary (MPB). The addition of KNN intrinsically changes the structural nature of the system with the shift of MPB from MPB(I) between ferroelectric rhombohedral and ferroelectric tetragonal phases to MPB(II) between ferroelectric rhombohedral and relaxor pseudocubic phases. As the MPB(I) switches to MPB(II), large piezoelectric response with d(33) similar to 150pC/N that obtained for BNT-0.20BKT near MPB(I) almost disappears. Instead, a significant jump of electric-filed-induced strain S up to 0.32%-0.46% (S-max/E-max = 400-575 pm/V) is achieved near MPB(II) due to the shift of the ferroelectric-relaxor transition temperature TF-R down to room temperature. In this study, giant strain similar to 0.46% occurs in a very narrow region in the BNT-BKT-KNN system with x = 0.20, y = 0.01, which lies on an underlying tricritical triple point of a rhombohedral (R), tetragonal (T), and pseudocubic (Pc) phases. In-situ high-energy X-ray scattering experiments with external electric field reveal an initial electric-field-induced distortion from the Pc structure for the MPB(II) compositions, while those with single R phase shows no such distortion, which suggests that the large strain achieved near the MPB(II) is likely to be induced by the electric-field-induced structure distortion due to its relative instability structure. We believe that the discovery of a compositional line in the pseudo-ternary system, where the strain response is consistently derivable, should be useful for designing high-performance piezoelectric materials in other BNT-based systems by searching MPBs.

Conventional coherent illumination provides the interference at high orders necessary for microtopography. However, the resulting interferogram is not a true, undistorted contour map of the specimen, nor is there any direct method of assessing the distortion. In addition, coherent illumination gives poor resolution, and when vertical illumination is used reflections in the objective reduce the contrast. These problems are all ameliorated by using incoherent illumination limited to a small range in angle relative to the plane of the reference reflector but unconfined in azimuth, i.e., the illumination produced by an annular source in the back focal plane of the illuminating lens.


The aim of this paper is to introduce and solve the following p-radical functional equation related to quartic mappings. where f is a mapping from R into a vector space X and p ≥ 3 is an odd natural number. Using an analogue version of Brzd¸ek's fixed point theorem [13], we establish some hyperstability results for the considered equation in non-Archimedean Banach spaces. Also, we give some hyperstability results for the inhomogeneous p-radical functional equation related to quartic mapping.


abstract This Briefing relates the experiences of women in a state-run institution in 2008 at the height of Zimbabwe's economic and political crisis. The crisis, characterised by record inflation and massive food, basic commodities and currency shortages, impacted negatively on the state's ability to provide key services. Bako Redonhodzo Old People's Home was severely affected. The British charity HelpAge cut its funding in 2008 as foreign aid into Zimbabwe continued to dwindle during the political crisis in the country. The Home had little or no assistance from government and was dependent for its survival on well-wishers and non-governmental organisations (NGOs). Within this context of crisis and poverty, we sought to find out in what ways gender influenced the experiences of elderly people at the Home. Using qualitative research methods, the research reflects that old age is intricately linked to class and gender. Gender analysis of the experience of the residents of Bako Redonhodzo Home reflect that elderly women were precariously situated and experienced the crisis in ways that reflect specific gendered needs. Their vulnerabilities and desires distinguished them from their male counterparts in the time of crisis, where shortages and lack of social security were the defining features of existence.


The word known peat is growth on organic systems where the plant growth is fast, but soils are defined as a partially decomposed organic matter deposit due to poor aeration and low temperature grades [1]. Peat is also named as turf and turba in different literatures owing to its unique property to natural areas called peatlands, bogs, mires, moors, or muskegs. The formation of such deposits is not related to particular climate regions, but it can occur wherever appropriate conditions are present. Organic soils are presented in all the continents of the world. Organic soils are mainly presented under tropical climates with above 60° northern latitudes, and about 450–500 million hectares of total world reserved areas. It is documented that about 150 million hectares of organic lands and about two-third of the world reserves are found in Russia and Canada [2].


peninsular rock agama on the 16th Nov 2009 in Rishi valley, Andhra Pradesh, India (13o32' N, 78o28' E; ca. 750m elevation), RS (first author) observed a large adult male Psammophilus dorsalis holding a medium sized Hemidactylus species between its jaws. The agamid was sighted with the mid-body of the gecko in its jaws at 10:30 h on a sheet-rock. Soon, the agamid made another powerful bite with its inner teeth and swallowed it alive, head first. RS assumed the size of the gecko to be around 40 mm from snout to vent. The adult male agamid measured 140mm from snout to vent and weighed 82g. The gecko was identified as Hemidactylus treutleri by the large spines on the tail and large keeled tubercles on the dorso-lateral side of the body. The identification of the gecko was further supported by the fact, that the survey site yielded only H. treutleri and no other gecko. The Peninsular rock agama P. dorsalis (Gray, 1831) occurs in most of Peninsular India, Madhya Pradesh and along the hills of the Eastern Ghats (Smith, 1935; Daniel, 2002; Chandra and Gajbe, 2005). Its food was considered to consist almost entirely of insects (Daniel, 2002; Radder et al., 2005). Hemidactylus treutleri Mahony, 2009 was recently described from Hyderabad, Andhra Herpetology Notes, volume 3: 033-035 (2010) (published online on 1 February 2010)


To support and control different design processes using Concurrent Engineering concept, all the information required in different design process must be complete, unique and most importantly, sharable. By close look at the assembly process and design process, this paper proposes an integrated information model of a product based upon its assembly relationship-- the assembly model. With all assembly information recorded and inheritated, an assembly model enables us to develop a product (rather than parts) oriented CAD system, to support top-down design process and, to control multiple design tasks and processes concurrently and ensure the consistency of the design model.

Deductive object bases (DOBs) attempt to combine the advantages of de-ductive relational databases with those of object-oriented databases. From an application perspective it is often not clear for what kind of applications this combination yields signiicant advantages. We argue for supporting distributed design environments by deductive object bases as repositories and summarize experiences made with our system ConceptBase.


ABSTRACT
In the southern coastline of the province of Guantanamo, Cuba, there are communities that have lost several hectares of soil and biodiversity due to land mismanagement. "Los Cerezos" community is located in the municipality of Imias, as part of the "Eliomar Noa" UBPC (Basic Unit for Cooperated Production), which uses 99.2% of their areas for livestock raising. The land is on hills covered with xerophytic bushes; signs of degradation are clearly observed. Restoration is one alternative to revert this situation. It constitutes an effective preservation technique implemented by man to achieve optimum recovery of degraded ecosystems close to their original states. The aim of this paper is to evaluate the results achieved after recovery of local soils, using restoration techniques. Research was done in a fragmented forest, on typical red-brown fersiallitic soil, where the limiting factors were determined (rills, slopes, effective depth, organic matter content, rocks, and erosion), as well as other negative factors that may have an effect on vegetation growth. Common Ligum-vitae (Guaiacum officinalis L.) was used for reforestation due to its adaptability to the ecosystem. The restoration works helped create the conditions for progressive recovery of the areas and mitigate soil degradation, with a decrease in losses of 1 036 t. ha-1 every year, thanks to barrier accumulation.


Classical planning is useful because it generates a partially ordered set of steps to achieve a goal consistent with the planner''s world model. Situated activity is useful for agents which responds quickly to changes in the interactive world. Unfortunately, everyday-world activity cannot rely on the costly, brittle plans of a theorem proving, nor can it resort to the stateless decisions of a situated automaton to cope with delayed feedback from the world. The only way for an agent to carry out long-term tasks in complex, dynamic worlds is to build a planning system that retrieves competent plans quickly, yet recover when its expectations fail. Furthermore, when an agent returns to a similar problem, it should avoid repeating the same mistakes. Case-based planning is the only planning paradigm which accounts for both failure tolerant planning and learning from failure. By re-using cases, MAYOR quickly retrieves and executes a plan. By monitoring the expectations associated with every plan, MAYOR determines when a plan underperforms, and recovers from the expectation failure using an approximate, causal model of the world to determine the cause of the failure. Lastly, MAYOR stores away factors which predicted the failure, and avoids the the failure in the future. This paper describes how MAYOR uses plans in the complex, dynamic world SimCity.


A survey of interactions of membrane filters with viruses has included 28 types of membranes, 4 types of enteroviruses, and 1 reovirus. Losses of these viruses in filtration, due to adsorption to the filter membranes, appear to be governed by three factors: the chemical composition of the filter membrane, the ratio of pore diameter to the diameter of the virus particle, and the presence of substances, such as those occurring in serum, which interfere with adsorption. Membranes of cellulose triacetate and of certain other materials have a very low affinity for these viruses. Cellulose triacetate filters adsorb virtually none when the pore size exceeds the virus diameter by a factor of more than 3. At porosities nearer the virus diameter, even low‐affinity membranes adsorb large quantities of virus unless serum or some other additive interferes. Cellulose nitrate membranes, in the absence of interfering substances, adsorb enterovirus significantly at a pore size 285 times the virus diameter.


This paper aims to synthesize the development of entrepreneurship with an analytical approach. After the theoretical framework, the term entrepreneurship is conceptualized with the analysis of the characteristic features of an entrepreneur in relation to the managerial roles associated with the five stages of the life cycle of a firm. This is followed by the presentation of a catalogue of factors that aid the development of sustainable entrepreneurship.


In plate girder with slender web the big transverse forces lead to web buckling produced with shear. One of the ways to increase stability of web near supports is to install stiffeners. In work the task of finding of critical stresses of clamped rectangular plate with installed inclined stiffener is considering. Investigations were performed with the finite element method and were checked with the experiment. Recommendations were given on choice of optimal size of stiffener.

In 2014–2015, 13,477 Mongolian schoolchildren (5833 boys and 7644 girls from different regions of the country), aged 8–17, were subjected to a comprehensive biological study. The program included 50+ anthropometric and anthroposcopic traits. Out of this set, bodily dimensions and functional parameters were used for the present paper. Their analysis was carried out among residents of mountain-taiga, steppe, and desert zones, which are still the main ecological niches of Mongolia. The urban sample (the best known Mongolian population, which included only subjects born and living in Ulaanbaatar) was used as a control group. The urban children and adolescents, as well as those living in the mountain-taiga zone, are characterized by maximal average values of the parameters. In the capital, these parameters are mostly affected by the living conditions, which are the best, confirming the results of previous studies. At the same time, the stressful urban factors account for higher indicators of the hemodynamic system in urban schoolchildren. The resemblance of these characteristics in steppe and desert dwellers results from relatively similar climatic conditions and physical stress patterns.


It has recently been suggested that the lifetime of the lowest triplet state in multiphoton-excited C60 is much longer than anticipated. If true, this would invalidate the assumption of internal thermal equilibrium in the description of statistical decay processes of the molecule, such as thermionic emission. We present pump–probe measurements which show that the lifetime is below 1 μs at vibrational excitation energies of 6.5 eV, and that it decreases further to 40 ns at 10 eV.


SUMMARY  Cardiovascular disease (CVD) is the leading cause of death in people with Type 1 diabetes (T1D), and improvements in CVD outcomes in the general population in recent decades are not mirrored in T1D populations. It is likely that CVD outcomes are worse for childhood-onset T1D due to a longer duration of disease and other important pathophysiological factors. However, repeated surveys show that screening for and treatment of CVD risk factors during adolescence is currently extremely poor. Here, we provide an overview of CVD in T1D, with a focus on aspects relevant to pediatric diabetes healthcare practitioners.

This article presents a new approach for security management in digital cinema applications. Metameric blacks are used as a new try for cinematic-film protection procedures, which are used in theatre projection systems. The information given by the capturing device in production time decomposes to its base spectra and makes an unacceptable image quality for camcorders by adding a specific metameric black to it. This procedure takes place during the exhibition, and the camcorders take poor quality pictures although the image may not have any changes in its quality for the audience. This try tends to reach the goal of security management during the movie plays and may be a new method to keep the rights of producers against digital theft. © 2008 Wiley Periodicals, Inc.

Microstructures on heat transfer surfaces can enhance heat transfer. This effect appears during the induction period of the crystallization fouling process where often a negative fouling resistance occurs. It is interpreted by the increase in near-wall turbulence due to first crystals growing on the surface resulting in the observed heat transfer enhancement [1]. Man-made microstructures in the same scale may utilize this positive effect in single-phase convective heat transfer. Plain copper plates with systematically and randomly distributed structures of 100 to 500 μm were designed and manufactured. Number, size, design, and allocation of the microstructures were varied. The plates were applied to a heat transfer test rig that allows investigation of Reynolds numbers between 1,000 and 17,000. The heat transfer can be calculated from temperature measurements and compared to smooth surfaces. Microstructures show an increase of heat transfer, described by the Nusselt number, up to 18% in the turbulent regime compared to a smooth plate. In laminar flow, a maximum of the Nusselt number was observed for some geometries. All results are strongly dependent on the design of the probes. These results show the potential for the optimization of microstructured surfaces to maximize heat and, subsequently, mass transfer rates.


The revolutions and protests that have spread across the globe since 2008 have been seen as a watershed moment. In this article we examine the relationships between urban space and politics that have emerged across these events. We draw upon the political philosophy of Jacques Rancière to provide a framework to understand some events of this period as political moments and, in addition, attempt to build upon Rancière's work to trace out the geographical dimensions of politics. The paper concludes with a consideration of the counter-revolutionary projects enacted by current social orders.


As the issue of power quality becomes increasingly prominent in recent years, this paper has made a focused research on how to coordinate, control and operate several intelligent low-voltage power distribution equipments including reactive power compensation device, active power filter (APF), low-voltage three-phase load balancing equipment and pressure regulator and offered a technical plan for improving power quality. As per on-site trial operation, a systematic evaluation of effects of this intelligent coordination and control system on improving power quality is made.


The records of 47 patients with no cirrhosis who underwent 56 liver resections under total vascular exclusion (TVE) for malignant tumours, both primary and secondary, were reviewed to study the effects of TVE. The mean(s.e.m.) blood loss was 1651(233) (median 1200 (range 200–8500)) ml and the mean(s.e.m.) intraoperative blood transfusion 930(100) (median 700 (range 0–2800)) ml. In 18 liver resections (32 per cent) no blood transfusion was administered. The mean(s.e.m.) postoperative hospital stay was 19·7(14·2) days. The 30‐day operative mortality rate was nil but the hospital mortality rate was 4 per cent. Postoperative prothrombin time was influenced by the amount of liver resected and the duration of TVE but not by the amount of blood transfused. Postoperative serum levels of aspartate aminotransferase and bilirubin were not influenced by either the amount of liver resected or the duration of TVE.


The optical reflectivity spectra of the single-crystal Bi-based cuprates, ${\mathrm{Bi}}_{2}$${\mathrm{Sr}}_{2}$${\mathrm{CaCu}}_{2}$${\mathrm{O}}_{8+\mathrm{x}}$ and ${\mathrm{Bi}}_{2}$${\mathrm{Sr}}_{2}$${\mathrm{CuO}}_{6+\mathrm{x}}$, were measured in a wide energy range from 0.05 to 40 eV, and analyzed through the Kramers-Kronig relation. The obtained spectra are different from other superconducting cuprates, such as (La,Sr${)}_{2}$${\mathrm{CuO}}_{4}$ and ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{\mathrm{x}}$, which might be ascribed to the existence of the characteristic ${\mathrm{Bi}}_{2}$${\mathrm{O}}_{2}$ layer. The optical excitations within ${\mathrm{Bi}}_{2}$${\mathrm{O}}_{2}$ layer start from 2 eV or higher energy, so it is unlikely that the electrons in the ${\mathrm{Bi}}_{2}$${\mathrm{O}}_{2}$ layer contribute to low-energy excitation or dc conduction in this family of high-${T}_{c}$ superconductors.


From the outset of the Black experience in America there has existed a plethora of interpretations of what role blacks do have in the operation and values of the country, as well as of how blacks should respond to the country and its laws and institutions-and ambivalence has always prevailed. The early arguments (white initiated, but, in part, black endorsed) ran: slavery is not the best of conditions, and it is, indeed, trying to be considered a cipher in the eyes of both social convention and the law, but there is an opportunity to have a religious experience [read: Christian experience] which otherwise would be lacking in black lives. It never was a good argument, of course, and it broke down for most people, black and white, who could think at all by the turn of the nineteenth century. But later a more perplexing ambivalence emerged-made more perplexing by the fact that, following Emancipation, blacks did seem to have some options-oppression (social, political, economic, and legal) on one hand, as against the promise (and occasional actuality) of opportunity in all of those areas, on the other. Was open revolt still called for? If so, to what specific end? Or should America and her various corruptions simply be abandoned? If so, in favor of what new geographical location? Or was perpetual "in-house" agitation against injustice the most practical course of action? Obviously, given the relatively few revolts and the relatively few blacks who have abandoned America-historically, most black Americans have chosen this last option. It is probably equally accurate to say, however, that many of the best black minds have argued, with conviction and logic, the wisdom of the other positions. Two such thinkers and writers were Martin R. Delany, a physician and social theorist, and Sutton Griggs, a Baptist minister and race lecturer. What these men have in common is that they wrote the only two revolutionary novels written by black Americans in the nineteenth century, Delany's Blake; or, The Huts of America (published serially, intermittently, between 1859 and 1862), and Griggs's Imperium in Imperio (1899). The theories of black revolution in the novels, however, take substantially different directions. Delany, writing before the Emancipation Proclamation,


Soft hashing, also known as robust hashing or perceptual hashing, consists of summarising multimedia data, so as to obtain a concise representation called a hash value. There has been an increasing interest in the soft hashing problem recently. Techniques implementing soft hashing intend to mirror the behaviour of cryptographic hashing, when the information to be hashed can be subject to different kinds of distortion. Many heuristic techniques for undertaking soft hashing of images and other multimedia data have been devised. Except for some attempts, a framework giving solid guidelines to solve the problem is largely lacking. We provide one possible approach to undertake the modelling of robust soft hashing, detailing the basic problems involved. We show how some prior schemes partly fit into our model.


Objective To explore and compare the diagnostic significance of mammography and sonography in non-palpation breast lesions(NPBLs).Methods The clinical data of 87 non-palpable breast lesions in 77 patients were analyzed retrospectively.All patients were examined both by mammography and sonography.Pathologic diagnosis was made with the tissues obtained by core needle biopsy or operative resection.The age and menstrual state of benign and malignant cases were analyzed.The imaging features of mammography and sonography in non-palpable breast cancer(NPBC) were summed up,and diagnostic potency of the two measures were evaluated.Results Among the 87 non-palpable breast lesions,20(23%) of 20 patients were pathologically diagnosed as breast cancer,of which 19(95%) lesions were in 0-I early stage.67(77%) breast lesions from 57 patients were diagnosed as benign lesions.The patients with non-palpable breast cancer were significantly older than those with benign NPBLs(P0.01),but no significant difference in menstrual state existed between the two groups.The diagnostic accuracy of mammography and sonography were 75%(15/20) and 55%(11/20),respectively.The imaging features of non-palbable breast cancer were malignant calcification and ill-defined low echo-level areas,and 10 out of 15(67%) positive lesions in mammography and 6 out of 11(55%) positive lesions in sonography were diagnosed as breast cancer.The sensitivity,specificity and accuracy of mammography(75%,64% and 67%,respectively) were statistically higher than that of sonography(55%,21% and 29% respectively) in the diagnosis of non-palpable breast lesions.Twenty patients with breast cancer underwent tumor resection with wire localization led by mammography or sonography.Eleven patients underwent the operation with preservation of breast.Conclusion Mammography and sonography,especially mammography,play an important role in early detection,early diagnosis and early treatment of non-palpable breast cancer.


This paper deals with some problems of measurement error analysis for flow measurement by electromagnetic flow meter. Two main groups of errors are discussed. The first group of errors is caused by various flow parameters which differ from the flow characteristics during calibration. The authors present a new method of errors estimating, called the moving stream method that allows to estimate on error of a flow meter during the design stage much more precisely than classical methods. The second group of errors is caused by a variation of liquid level in a flow channel during flow meters' operation. Authors propose a selecting an appropriate liquid level as a parameter in designing the exciting coil of electromagnetic flow meter as a best way of that error minimization. Some results of numerical simulation are presented.

The paper will discuss how suppliers, operators and research can contribute to improve tube life, considering increasing production and quality demands.


Feingold et al. (1998) have reported the use of ultrasound in third-trimester diagnosis of nail–patella syndrome (NPS). While ultrasound has the advantage of being non-invasive, the usefulness of third-trimester diagnosis is limited. The fine mapping of the NPS locus with genetic markers (McIntosh et al., 1997), and subsequent identification of LMX1B as the mutated gene (Dreyer et al., 1998; Vollrath et al., 1998), allows first-trimester diagnosis by analysis of DNA obtained via chorionic villus sampling. Indeed, DNA-based prenatal diagnosis of NPS has been performed in at least three cases since 1995 (McIntosh et al., unpublished data). We present the details of one family as an example (Fig. 1). The proband was brought to our attention after the birth of an affected son. The proband was reported in some detail by Ben Bassat et al. (1971). He had several futile surgical attempts to improve the restricted range of motion of his elbows. At present his GFR is below 50 per cent, he has very little body fat, has soft skin and prominent veins, and suffers from severe myopia, but does not have glaucoma. The son, like his father, has antecubital pterygia and other typical findings of the syndrome, but he does not have evidence of renal disease. Antecubital pterygia are an infrequent finding in NPS, present in less than 4 per cent of cases (Rizzo et al., 1993). It has been suggested that all adult NPS patients, with antecubital pterygia, have an associated renal disease (Rizzo et al., 1993).


Johns Hopkins University Medical School. He had just given an unprecedented and interesting lecture on comparative oncology of cold-blooded animals. Largely through his effort with many scientists, the field of experimental fish carcinogenesis in the United States and other countries was born (3, 7). It is fitting that Dr. Bunton, as one of these scientists, has been asked to write a review to reflect our present understanding of the experimental use of fish in studying chemical carcinogenesis. Because of her contributions to


The key of development for reservoirs with bottom water is to depress water coning or control coning of bottom water,prolong the water-free oil recovery period as much as possible,and make bottom water even displacing in order to reach the purpose of improving the developing results for reservoirs with bottom water.Aiming at the practical situations of Luliang oilfield,which has the following characteristics: its main producing formations-Jurassic and Cretaceous reservoirs consist of thin pays;most of the pays have medium or high permeability;all the pillar pays have edge and bottom water;there are no solid interlacing beds between pays and aquifers;oil and water distribution is complex;and water cut increases rapidly in oil wells during production, the application study of water coning controlling techniques is conducted.With visualized physical simulation facilities,the model is developed for the thinbed reservoirs with bottom water.The effective pack-off is set up below the thin pays when well completion is done without perforation.The sufficient optimization is conducted for the formula,usage and working parameters of all using work fluids and the pilot tests are performed in the fields.With selecting injection method,the packer is placed near the oil/water boundary of the thin pays to control the invasion of bottom water.The water cut of oil wells and the increasing velocity of water cut is controlled effectively.The target to control coning of bottom water and inhibit increase of water cut is reached.The good results are achieved.The techniques can widely used in the development practice for the thin-bed reservoirs with bottom water to control water and stabilize oil production.


Flexible manufacturing workshops (FMWs) are important part of modern manufacturing enterprises. An optimized layout of radio frequency identifications (RFIDs) in an FMW is of great significance to improve information perception quality and reduce RFID deployment cost. Therefore, the RFID network planning for an FMW is studied in this paper. Firstly, three common coverage requirements are analyzed, and a RFID reader radiation model and an FMW discrete grids model are constructed. Secondly, a 0–1 integer programming-based RFID network planning model is established with the optimization objectives of the RFID deployment cost, reader interference, and reading efficiency. Thirdly, a hierarchical clustering and gradient descent-based network planning approach is proposed to solve the network planning model. An FMW case in a flexible manufacturing enterprise is taken to verify the RFID network planning model and the hierarchical clustering approach. The results show that the proposed model and approach are effective.

Objective To investigate the inherent cholinergic system in immunocytes and immune organs of rats. Methods Immunofluorescence, flow cytometry and immunohistochemical method were used to detect the expression of nicotinic acetylcholine receptors α7 (nAChRα7), choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) in peripheral blood CD4+T lymphocytes, peritoneal macrophages, synovial cells and celiac lymph nodes of rats. Results The presence of nAChRα7, ChAT and AChE in immunocytes and immune organs was detected. Macrophage of lymph node, peritoneal macrophages and synovial macrophage were abundant in expression of nAChRα7, ChAT and AChE. The lymphocytes of celiac lymph nodes were weak in expression and only less part of CD4+T lymphocytes in peripheral blood expressed nAChRα7 and ChAT(15.88%±0.753% and 23.09%±0.671%, respectively). Conclusion The inherent cholinergic system is widespread in immunocytes and immune organs. Macrophages and lymophacytes play different roles in the inherent cholinergic system.

Cerebrotendinous xanthomatosis (CTX) is a disorder of bile acid (BA) metabolism due to biallelic mutations in CYP27A1. The deposition of cholesterol and cholestanol in multiple tissues results, manifesting as neurologic disease in adults or older children. Neonatal cholestasis (NC) as a presentation of CTX is rare; it may self‐resolve or persist, evolving to require liver transplantation (LT).


Twenty hypertensive patients received single oral doses of pseudoephedrine 60 mg or placebo in a double-blind, randomised, crossover trial. Systolic, diastolic, mean arterial blood pressure, and heart rate were measured at 5 min intervals for 30 min prior to and 210 min after the administration of pseudoephedrine or placebo. Statistically significant differences between the two treatments were observed with changes in systolic blood pressure (P less than 0.03) and heart rate (P less than 0.01) but not in diastolic (P greater than 0.03) and mean arterial blood pressure (P greater than 0.1). Minor differences in the number of reported side effects between the two treatments were not statistically significant.


This work uses the intermediary quaternions in the design of a backstepping control technique with integral properties in order to perform an autonomous trajectory tracking using a quadcopter vehicle. Nowadays, in order to determine the orientation of a vehicle, most of the inertial systems of aircrafts can give directly the rotation matrix and taking advantage of this fact, the intermediary quaternions can be determined in a simple way from this matrix. Moreover, one specific orientation corresponds to only one intermediary quaternion and this helps to cope the unwinding phenomenon presented when working with the classical quaternions. The proposed control algorithm is validated numerically and experimentally when the quadrotor follows a circular trajectory. In addition, during the simulation part, some external perturbations and white noise were added in order to test the robustness of the algorithm.


To estimate the tectonic displacement history of the Yangsan Fault (YSF) in the Cretaceous Gyeongsang Basin (GB), SE-Korea, gravity field measurements were implemented and interpreted. A total of 8 000 ground-measured gravity data were compiled and deployed to calculate the Bouguer and residual gravity field. The residual field shows that the mean value in the southern segment of the YSF is very similar to that of the northern segment, meanwhile that of the central segmentation is significantly lower than those of the other segmentations. This implies that the crustal structure and petrophysical properties of the central segment differ significantly from those of the other segments. Applying dip curvature analysis to enhance the image of the residual gravity field, we find that (1) the Gaum fault system (GF) in the western-and middle part of the GB extends up to the YSF, where A-type granite outcrops are observed. (2) The middle- and eastern segments of the GF that formed before tectonic motion of the YSF are revealed in turn in areas east of the YSF, which were now covered by the younger sedimentary basin. (3) The middle segment of the GF which occupies between the YSF and the Yeonil tectonic line (YTL) has been displaced approximately 25 km southward from the main GF trace. (4) The easternmost segment is revealed buried in the eastern side of the YTL, which is displaced southward about 18 km from the main GF trace. Comparing all the available geoscientific datasets, we conclude that the right-lateral tectonic movement of the YSF, and the deeply buried middle segment of the GF remained stationary, while the most eastern segment of the GF is reversely moved to the north through left-lateral strike movement of the YTL.


This paper deals with the jointed decision question on ordering and pricing for a short-life-cycle product under stochastic multiplicative demand depended selling price. According to the marketing practices, which retailers sell their products in different periods with the different marketing policies, we depict the jointed decision question with a stochastic dynamic programming model from the view of the centralized system. Then, we prove that the expected profit function are concave on decision vectors respectively, and develop the decision method for ordering and pricing. Lastly, we design iterative search algorithm to find the optimal decision vectors.


Size-exclusion experiments of alcohols, mono- and dicarboxylic acids, aromatic acids, and amino acids were conducted. Two columns with different gel packings (TSK HW 50 S and TSK G2000SW) were used to determine the influence of the gel core structure on the elution volume of organic substances. Neither for the polymer based gel nor for the silica based gel specific interactions, especially hydrophobic interactions, could be neglected. For both alcohols and monocarboxylic acids the elution volume increased with an increasing number of carbon atoms. It was found that aromatic compounds interacted strongly with both gels. Whereas alcohols were not affected by differences in ionic strength between sample and eluent, the elution volume of carboxylic acids was strongly influenced. In combination with a multidetector system (UV absorption, fluorescence, dissolved organic carbon, electrical conductivity) changes in the chromatographic behavior of these compounds due to differences in ionic strength between sample...


Laminated object manufacturing (LOM{reg_sign}) is one of several manufacturing systems developed recently to produce a solid part directly from a 3D CAD drawing, without the use of hard tooling or dies. These systems begin with a conventional 3-D CAD file--solid model or wire-form model--that is converted to a de facto standard format for flexible manufacturing (.STL file) and sliced into thin cross sections by a separate computer program. These slices are then used to control the equipment that produces the component slice-by-slice. This paper describes an application of the CerLOM approach to produce multilayered composites of ZrO{sub 2} and Al{sub 2}O{sub 3}. The choice of materials is based on previous studies that showed that a beneficial increase in toughness can be achieved with multilayered microstructures in this system. The toughness increase is due to martensitic transformation in the ZrO{sub 2}phase. Because the CerLOM process produces the component directly from a CAD file without tooling, dies or molds, the production is rapid and cost effective. Components of complex shape can be fabricated readily, and design changes can be made easily.
