Classification of cubic auxetics
Authors: Goldstein Robert V. , Gorodtsov Valentin A. , Lisovenko Dmitry S. 
Published: September 2013

Two‐parameter analysis of auxetics among the cubic crystals is proposed. A brief analysis of the equivalence of this two‐parameter consideration and other approaches is given. The main result of this paper is the classification of partial auxetics with a single dimensionless complex, which is composed of the crystals elastic compliances. The auxetic surface separates the regions with negative and positive Poisson's ratio. The character of its changes with change of the dimensionless complex is determined. The critical value of the complex where a topological rearrangement of the auxetic surface occurs is obtained. The distribution of partial auxetics in zones with different values of the dimensionless complex was found. The sign of another dimensionless parameter influences the location of a region with negative Poisson's ratio relative to the auxetic surface.

Published: September 2013

AbstractSilver microgrid/TiO2/ITO (indium tin oxide glass) sandwich‐structure photodetectors with various pore sizes are fabricated by a microsphere lithography strategy. This ultraviolet (UV) detector possesses ohmic contact characteristics. The high UV transmittance results from an enhanced bulk plasmon effect of the silver microgrid electrode. Photoelectric properties of the sandwich structure with various pore sizes are discussed. The short transport distance of carriers and the low blocking of incoming UV light are the main reasons of the high activity for silver microgrid/TiO2/ITO sandwich‐structure photodetectors.

A generalized robust H ∞  filtering for singular Markovian jump systems and its applications
Authors: Wang Guoliang , Zhang Peng , Zhang Qingling 
Published: September 2013

SUMMARYIn this paper, a generalized robust H ∞  filtering method is proposed for a class of singular Markovian jump systems, whose generality is mainly embodied that the desired filter could bear perturbances in terms of uncertainties on its parameter matrices. Firstly, an LMI condition of robust mode‐dependent filter is developed. Based on the given result, a new approach to mode‐independent H ∞  filter is presented, which establishes a direct connection between mode‐dependent and mode‐independent filters. Secondly, when the transition rate matrix is with elementwise bounded uncertainties or partially unknown, sufficient conditions of such robust mode‐dependent and mode‐independent filters are all developed within LMI frameworks. Finally, a numerical example is used to demonstrate the effectiveness of the proposed methods. Copyright © 2013 John Wiley & Sons, Ltd.
H ∞  model reduction for discrete‐time positive systems with inhomogeneous initial conditions
Authors: Shen Jun , Lam James 
Published: September 2013

SUMMARYThis paper addresses the H ∞  model reduction problem of discrete‐time positive linear systems with inhomogeneous initial conditions. For an asymptotically stable positive system with non‐zero initial condition, our goal is to approximate it by a reduced‐order initial‐valued positive system without introducing significant error. We establish a necessary and sufficient condition for the existence of a desired reduced‐order model such that the output error between the original system and the reduced‐order one is bounded by a weighted sum of the magnitude of the input and that of the initial condition. Moreover, based on congruent transformation and the dual form of bounded real lemma, several equivalent conditions are derived in terms of LMIs and an iterative convex optimization algorithm is developed accordingly. Finally, an illustrative example is presented to show the effectiveness of the proposed methods. Copyright © 2013 John Wiley & Sons, Ltd.
Contention management in federated virtualized distributed systems: implementation and evaluation
Authors: Salehi Mohsen Amini , Toosi Adel Nadjaran , Buyya Rajkumar 
Published: September 2013

SUMMARYThe paper describes creation of a contention‐aware environment in a large‐scale distributed system where the contention occurs to access resources between external and local requests. To resolve the contention, we propose and implement a preemption mechanism in the InterGrid platform, which is a platform for large‐scale distributed system and uses virtual machines for resource provisioning. The implemented mechanism enables the resource providers to increase their resource utilization through contributing resources to the InterGrid platform without delaying their local users. The paper also evaluates the impact of applying various policies for preempting user requests. These policies affect resource contention, average waiting time, and imposed overhead to the system. Experiments conducted in real settings demonstrate efficacy of the preemption mechanism in resolving resource contention and the influence of preemption policies on the amount of imposed overhead and average waiting time.

Systemizing: A cross‐cultural constant for motivation to learn science
Authors: Zeyer Albert , Çetin‐Dindar Ayla , Md Zain Ahmad Nurulazam , Juriševič Mojca , Devetak Iztok , Odermatt Freia 
Published: September 2013

AbstractThe present study is based on the empathizing‐systemizing (E‐S) theory of cognitive science. It was hypothesized that the influence of students' gender on their motivation to learn science is often overestimated in the research literature and that cognitive style is more important for motivation than students' gender. By using structural equation modeling, and based on previous research, a precise causal model was formulated to test this hypothesis. Then, using multiple group confirmatory analysis, the model was tested in a cross‐cultural context that included four countries—Malaysia, Slovenia, Switzerland, and Turkey—and 1,188 upper secondary students. Data were collected using standard questionnaires on cognitive style and motivation to learn science. The results showed full mediation of systemizing—the second dimension of the E‐S theory—between gender and motivation. That is, gender had no direct impact on motivation, but systemizing explained 27% of the variation in students' motivation scores. The indirect impact of gender was significant but very low; it explained 1.5% of the variance, in favor of boys. Empathizing—the first dimension of the E‐S theory—had no impact on students' motivation scores. This causal model proved to be similar (invariant) in all four cultures. The results suggest that considering students' cognitive style, instead of or in addition to their gender, could lead to a better understanding of students' motivation to learn science. Science teaching methods that support both cognitive styles—systemizing and empathizing—could enhance students' learning of science. © 2013 Wiley Periodicals, Inc. J Res Sci Teach 50: 1047–1067, 2013
Wavefunction methods for the accurate characterization of water clusters
Authors: Howard J. Coleman , Tschumper Gregory S. 
Published: September 2013

Although the first ab initio Hartree–Fock computations of the water dimer were reported more than four decades ago, the detailed characterization of water clusters with sophisticated electronic structure techniques remains an important and vibrant area of research. The field of computational quantum chemistry has made significant advances since those pioneering studies. Geometry optimizations of the water dimer can now be carried out at the CCSDTQ level, and CCSD(T) energies can be computed with the aug‐cc‐pVTZ basis for clusters as large as (H2O)17. Some of these high‐level studies are starting to reveal that the electronic structure is harder to describe for some hydrogen bonds than others. For example, discrepancies between MP2 and CCSD(T) energetics tend to increase when there are qualitative differences in the hydrogen‐bonding networks of the water clusters being studied. This review highlights the recent and exciting work in this area and provides an overview of popular strategies for generating reliable properties and benchmark quality energetics for water clusters with correlated wavefunction methods.This article is categorized under:

Abstract
We report microbially facilitated synthesis of cadmium sulfide (CdS) nanostructured particles (NP) using anaerobic, metal-reducing Thermoanaerobacter sp. The extracellular CdS crystallites were &lt;10 nm in size with yields of ~3 g/L of growth medium/month with demonstrated reproducibility and scalability up to 24 L. During synthesis, Thermoanaerobacter cultures reduced thiosulfate and sulfite salts to H2S, which reacted with Cd2+ cations to produce thermodynamically favored NP in a single step at 65 °C with catalytic nucleation on the cell surfaces. Photoluminescence (PL) analysis of dry CdS NP revealed an exciton-dominated PL peak at 440 nm, having a narrow full width at half maximum of 10 nm. A PL spectrum of CdS NP produced by dissimilatory sulfur reducing bacteria was dominated by features associated with radiative exciton relaxation at the surface. High reproducibility of CdS NP PL features important for scale-up conditions was confirmed from test tubes to 24 L batches at a small fraction of the manufacturing cost associated with conventional inorganic NP production processes.

Authors: Thuan Nguyen Huy , Sohng Jae Kyung 
Published: September 2013

AbstractGlycosylation is one of the most important post-modification processes of small molecules and enables the parent molecule to have increased solubility, stability, and bioactivity. Enzyme-based glycosylation has achieved significant progress due to advances in protein engineering, DNA recombinant techniques, exploitation of biosynthetic gene clusters of natural products, and computer-based modeling programs. Our report summarizes glycosylation data that have been published within the past five years to provide an overall review of current progress. We also present the future trends and perspectives for glycosylation.

AbstractObjectiveTo investigate promoters and barriers for cervical cancer screening in rural Tanzania.MethodsWe interviewed 300 women of reproductive age living in Kiwangwa village, Tanzania. The odds of attending a free, 2‐day screening service were compared with sociodemographic variables, lifestyle factors, and knowledge and attitudes surrounding cervical cancer using multivariable logistic regression.ResultsCompared with women who did not attend the screening service (n = 195), women who attended (n = 105) were older (OR 4.29; 95% CI, 1.61–11.48, age 40–49 years versus 20–29 years), listened regularly to the radio (OR 24.76; 95% CI, 11.49–53.33, listened to radio 1–3 times per week versus not at all), had a poorer quality of life (OR 4.91; CI, 1.96–12.32, lowest versus highest score), had faced cost barriers to obtaining health care in the preceding year (OR 2.24; 95% CI, 1.11–4.53, yes versus no), and held a more positive attitude toward cervical cancer screening (OR 4.64; 95% CI, 1.39–15.55, least versus most averse).ConclusionEfforts aimed at improving screening rates in rural Tanzania need to address both structural and individual‐level barriers, including knowledge and awareness of cervical cancer prevention, cost barriers to care, and access to health information.
Stillbirths and neonatal mortality as outcomes
Authors: Goldenberg Robert L. , McClure Elizabeth M. , Jobe Alan H. , Kamath‐Rayne Beena D. , Gravette Michael G. , Rubens Craig E. 
Published: September 2013

AbstractSeveral recent studies in low‐resource countries have claimed that training in—and increased use of—newborn resuscitation resulted in reduced stillbirth rates. In the present article, we explore the ability of various types of birth attendant in some low‐resource country locations to gather data that accurately differentiate a stillbirth from a live birth/early neonatal death. We conclude that, in many situations, it cannot be determined whether the infant was a stillbirth or a live birth/early neonatal death, and therefore the least‐biased description of study outcomes includes a combined stillbirth and live birth/neonatal death outcome. However, because defining the burden of stillbirth and neonatal death is important from a public health perspective, every effort should be made, in low‐income countries and elsewhere, to distinguish between stillbirths and live births/neonatal deaths and to report the results independently.
Enhancing Crisis Leadership in Public Health Emergencies
Authors: Deitchman Scott 
Published: September 2013

AbstractReviews of public health emergency responses have identified a need for crisis leadership skills in health leaders, but these skills are not routinely taught in public health curricula. To develop criteria for crisis leadership in public health, published sources were reviewed to identify attributes of successful crisis leadership in aviation, public safety, military operations, and mining. These sources were abstracted to identify crisis leadership attributes associated with those disciplines and compare those attributes with crisis leadership challenges in public health. Based on this review, the following attributes are proposed for crisis leadership in public health: competence in public health science; decisiveness with flexibility; ability to maintain situational awareness and provide situational assessment; ability to coordinate diverse participants across very different disciplines; communication skills; and the ability to inspire trust. Of these attributes, only competence in public health science is currently a goal of public health education. Strategies to teach the other proposed attributes of crisis leadership will better prepare public health leaders to meet the challenges of public health crises.

Vortex development on pitching plates with lunate and truncate planforms
Authors: Hartloper Colin , Rival David E. 
Published: September 2013

AbstractThe three-dimensional flow field and instantaneous forces are measured on pitching rectangular, lunate and truncate planforms of aspect-ratio four. The leading-edge vortex on the rectangular planform is compressed as it grows, and subsequently forms an arch-shaped vortex. For the lunate and truncate planforms, which both have identical spanwise leading-edge curvature but differ in planform area, outboard-directed convection of vorticity, rather than vortex stretching, mitigates arch-vortex formation. The vortical near wake that is formed by the planforms with spanwise leading-edge curvature is found to be strongly correlated with a favourable lift-to-drag ratio during the force-relaxation phase.

Impaired regulation of blood glucose levels in diabetes mellitus (DM) patients and the associated elevation of blood glucose levels are known to increase the risk of diabetic cardiomyopathy (DC). In the present study, a probiotic bacterium, Lactobacillus reuteri GMN-32, was evaluated for its potential to reduce blood glucose levels and to provide protection against DC risks in streptozotocin (STZ)-induced DM rats. The blood glucose levels of the STZ-induced DM rats when treated with L. reuteri GMN-32 decreased from 4480 to 3620 mg/l (with 107 colony-forming units (cfu)/d) and 3040 mg/l (with 109 cfu/d). Probiotic treatment also reduced the changes in the heart caused by the effects of DM. Furthermore, the Fas/Fas-associated protein with death domain pathway-induced caspase 8-mediated apoptosis that was observed in the cardiomyocytes of the STZ-induced DM rats was also found to be controlled in the probiotic-treated rats. The results highlight that L. reuteri GMN-32 treatment reduces blood glucose levels, inhibits caspase 8-mediated apoptosis and promotes cardiac function in DM rats as observed from their ejection fraction and fractional shortening values. In conclusion, the administration of L. reuteri GMN-32 probiotics can regulate blood glucose levels, protect cardiomyocytes and prevent DC in DM rats.

Published: September 2013

AbstractThe aim of the present study was to calculate the prevalence and intensity of intestinal helminths in the house mouse (Mus musculus) and the black rat (Rattus rattus) trapped in rural households of Yucatan, Mexico. Sampling was conducted during the rainy season from October to December 2011 and the dry season from January to March 2012. A total of 154M. musculusand 46R. rattuswere examined, with 84.2% ofM. musculusbeing infected with helminths compared with a significantly lower prevalence of 52.2% inR. rattus(P< 0.01). AdultM. musculuswere more likely to be infected with helminths (89%) than subadults (63%) (P< 0.01). Four helminth species were identified:Taenia taeniaeformislarvae,Nippostrongylus brasiliensis,Syphacia murisandTrichuris muris.Nippostrongylusbrasiliensiswas present more frequently inM. musculusthan inR. rattus(P< 0.01) and in adult mice compared to subadults (P< 0.01).Trichuris muriswas present only in adult mice. This is the first report ofN. brasiliensis,S. murisandT. murisin Yucatan, Mexico, as well as the first to report the presence ofN. brasiliensisinM. musculusfrom Mexico. The helminth fauna of commensal rodents present in households appears to constitute a low potential health risk to local inhabitants; however, it would be advisable to conduct further studies to better understand the public health risk posed by these rodent intestinal helminths.

AbstractObjective:To report previously unreported complications of bilateral sphenopalatine artery ligation.Subjects and methods:We present the case of a 45-year-old man who underwent bilateral sphenopalatine artery ligation to control intractable posterior epistaxis. After four months, he re-presented with nasal obstruction and crusting.Results and analysis:Examination under general anaesthesia showed posterior septal perforation and bilateral necrosis of the lower parts of the middle turbinates. The necrotic parts were excised. The patient had no more complaints.Conclusion:Following sphenopalatine artery occlusion, ischaemic necrosis is a potential risk in anatomical areas that receive their only arterial supply from this artery. The staging of bilateral sphenopalatine artery occlusion needs to be studied.
The association between common mental disorders and violence: to what extent is it influenced by prior victimization, negative life events and low levels of social support?

Published: September 2013

BackgroundFew studies have been published on the association between mental disorders and violence based on general population studies. Here we focus on different types of violence, adjusting for violent victimization and taking account of the limitations of previous population studies.MethodData were used from the first two waves of the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2), a nationally representative face-to-face survey of the general population aged 18–64 years (n = 6646). Violence was differentiated into physical and psychological violence against intimate partner(s), children or any person(s) in general. DSM-IV diagnoses were assessed with the Composite International Diagnostic Interview Version 3.0 (CIDI 3.0).ResultsPsychological violence occurs considerably more frequently than physical violence, but both showed almost identical associations with mental disorders. After adjustment for sociodemographic characteristics, most of the main categories of common mental disorders were associated with violence. The strongest associations were found for externalizing disorders (substance use, impulse-control, antisocial personality disorder). After additional adjustment for violent victimization, negative life events and social support, most diagnostic correlates lost their significance whereas substance use (in particular alcohol) disorders were still associated with most types of violence.ConclusionsThe increased risk of violent offending among people with common mental disorders, other than substance use disorders, can be attributed to factors other than their mental illness.
