Authors: Kiran Sumit K. , Nace Vaughn M. , Silvestri Maximilian A. , Monk Keith A. , Moloney Jeremy , Schmidt Loreen , Acosta Edgar J. 
Published: August 2014

AbstractThe partitioning of corrosion inhibitor (CI) products is a measure of their potential to protect oilfield pipelines. In this paper the hydrophilic–lipophilic deviation (HLD) model is first used to quantify their partitioning in terms of the characteristic curvature (Cc,act) of a series of anionic (alkoxylated phosphate esters) and cationic (alkoxylated amines, aromatic amines, imidazoline acetates and quaternary amines) actives. This parameter is expressed over a range of pHs within which pipeline corrosion occurs. The HLD model is next used to predict the partitioning of each active from water into toluene at increased salinities. Linear mixing rules are lastly used to predict the characteristic curvature of Product A (Cc,mix) as a function of the Cc,act of a subset of actives.
Supportive relationships within ongoing families: Cross‐lagged effects between components of support and adjustment in parents and young adult children
Authors: Lanz M. , Tagliabue S. 
Published: August 2014

ABSTRACTItaly is the first country in which the phenomenon of cohabitation of parents and young adult children was examined. From the earliest studies, it seemed clear that the transition to adulthood occurs within the family of origin: indeed, the successful outcome of this transition depends on the quality of family relationships. Using the Social Relations Model, this study examines the importance of the components of support within family relationships during the transition of young adults from university to job contexts (Kenny & La Voie, 1984). The cross‐lagged influence among the components of perceived support and the adjustment of family members has also been investigated. Findings show that family components of support are significant for perception in both parents and young adults. Furthermore, cross‐lagged models reveal different results for parents than for young adults. Discussion of results regarding the transition to adulthood and family theory is provided.
The wave-induced added mass of walking droplets
Authors: Bush John W. M. , Oza Anand U. , Moláček Jan 
Published: August 2014

AbstractIt has recently been demonstrated that droplets walking on a vibrating fluid bath exhibit several features previously thought to be peculiar to the microscopic realm. The walker, consisting of a droplet plus its guiding wavefield, is a spatially extended object. We here examine the dependence of the walker mass and momentum on its velocity. Doing so indicates that, when the walker’s time scale of acceleration is long relative to the wave decay time, its dynamics may be described in terms of the mechanics of a particle with a speed-dependent mass and a nonlinear drag force that drives it towards a fixed speed. Drawing an analogy with relativistic mechanics, we define a hydrodynamic boost factor for the walkers. This perspective provides a new rationale for the anomalous orbital radii reported in recent studies.
ON A DIAGONAL QUADRIC IN DENSE VARIABLES
Authors: KEIL EUGEN 
Published: August 2014

AbstractWe examine the solubility of a diagonal, translation invariant, quadratic equation system in arbitrary (dense) subsets$\mathcal{A}$⊂ ℤ and show quantitative bounds on the size of$\mathcal{A}$if there are no non-trivial solutions. We use the circle method and Roth's density increment argument. Due to a restriction theory approach we can deal with equations ins≥ 7 variables.
ON LENGTH DISTORTIONS WITH RESPECT TO QUADRATIC DIFFERENTIAL METRICS
Authors: SUN ZONGLIANG 
Published: August 2014

AbstractIn this paper, we consider the question about length distortions under quasiconformal mappings with respect to quadratic differential metrics. More precisely, letXandYbe closed Riemann surfaces with genus at least 2, andf: X → Ybeing aK-quasiconformal mapping. Given two quadratic differential metrics |q1| and |q2| with unit areas onXandYrespectively, whether there exists a constant$\mathcal C$depending only onKsuch that$\frac{1}{\mathcal C} l_{q_1} (\gamma) \leq l_{q_2} (f(\gamma)) \leq \mathcal C l_{q_1} (\gamma)$holds for any simple closed curve γ ⊂X. Herelqi(α) denotes the infimum of the lengths of curves in the homotopy class of α with respect to the metric |qi|,i= 1, 2. We give positive answers to this question, including the aspects that the desired constant${\mathcal C}$explicitly depends onq1,q2andK, and that the constant$\mathcal C$is universal for all the quantities involved.
To Concede or to Resist? The Restraining Effect of Military Alliances
Authors: Fang Songying , Johnson Jesse C. , Leeds Brett Ashley 
Published: August 2014

AbstractCreating institutions that effectively manage interstate conflict is a priority for policy-makers. In this article we demonstrate that military allies are well positioned to influence the crisis-bargaining behavior of both challengers and targets in ways that often lead to peace. Through a three-player game-theoretic model, we demonstrate that a target's alliances not only have an effect on the demand that the challenger makes, but also on the behavior of the target. When a target values an alliance highly, an ally's recommendation for settlement can encourage the target to concede to demands without further escalation. Our statistical analysis provides evidence in support of the theoretical finding. Allies can both deter challengers and restrain partners, and as a result, can encourage peaceful behavior not only from adversaries, but from member states as well. Our study thus sheds new light on the role of military alliances as potential conflict management devices.
Co-extinct and critically co-endangered species of parasitic lice, and conservation-induced extinction: should lice be reintroduced to their hosts?
Authors: Rózsa Lajos , Vas Zoltán 
Published: August 2014

AbstractThe co-extinction of parasitic taxa and their host species is considered a common phenomenon in the current global extinction crisis. However, information about the conservation status of parasitic taxa is scarce. We present a global list of co-extinct and critically co-endangered parasitic lice (Phthiraptera), based on published data on their host-specificity and their hosts’ conservation status according to the IUCN Red List. We list six co-extinct and 40 (possibly 41) critically co-endangered species. Additionally, we recognize 2–4 species that went extinct as a result of conservation efforts to save their hosts. Conservationists should consider preserving host-specific lice as part of their efforts to save species.
Enhanced laser ion acceleration with a multi-layer foam target assembly

Published: August 2014

AbstractInteraction of a linearly polarized Gaussian laser pulse (at relativistic intensity of 2.0 × 1020 Wcm−2) with a multi-layer foam (as a near critical density target) attached to a solid layer is investigated by using two-dimensional particle-in-cell simulation. It is found that electrons with longitudinal momentum exceeding the free electrons limit of meca02/2 so-called super-hot electrons can be produced when the direct laser acceleration regime is fulfilled and benefited from self-focusing inside of the subcritical plasma. These electrons penetrate easily through the target and can enhance greatly the sheath field at the rear, resulting in a significant increase in the maximum energy of protons in target normal sheath acceleration regime. The results indicate that the maximum proton energy is enhanced by 2.7 times via using an assembled target arrangement compared to a bare solid target. Furthermore, by demonstration of this assembly, the maximum proton energy is improved beyond the optimum amount achieved by a two-layer target proposed by Sgattoni et al. (2012).

Published: August 2014

AbstractObjectiveAdherence to a Mediterranean diet is associated with significant improvements in health status. However, to date no systematic review and meta-analysis has summarized the effects of Mediterranean diet adherence on the risk of type 2 diabetes mellitus.DesignElectronic searches for randomized controlled trials and cohort studies were performed in MEDLINE, SCOPUS, EMBASE and the Cochrane Trial Register until 2 April 2014. Pooled effects were calculated by an inverse-variance random-effect meta-analysis using the statistical software Review Manager 5·2 by the Cochrane Collaboration.SettingMeta-analysis of randomized controlled trials and cohort studies.SubjectsEligibility criteria: 19+years of age.ResultsOne randomized controlled trial and eight prospective cohort studies (122 810 subjects) published between 2007 and 2014 were included for meta-analysis. For highest v. lowest adherence to the Mediterranean diet score, the pooled risk ratio was 0·81 (95 % CI 0·73, 0·90, P<0·0001, I2=55 %). Sensitivity analysis including only long-term studies confirmed the results of the primary analysis (pooled risk ratio=0·75; 95 % CI 0·68, 0·83, P<0·00001, I2=0 %). The Egger regression test provided no evidence of substantial publication bias (P=0·254).ConclusionsGreater adherence to a Mediterranean diet is associated with a significant reduction in the risk of diabetes (19 %; moderate quality evidence). These results seem to be clinically relevant for public health, in particular for encouraging a Mediterranean-like dietary pattern for primary prevention of type 2 diabetes mellitus.
Biotic interactions and temporal dynamics of the human gastrointestinal microbiota
Authors: Trosvik Pål , de Muinck Eric Jacques , Stenseth Nils Christian 
Published: August 2014

Abstract
The human gastrointestinal (GI) microbiota is important to human health and imbalances or shifts in the gut microbial community have been linked to many diseases. Most studies of the GI microbiota only capture snapshots of this dynamic community at one or a few time points. Although this is valuable in terms of providing knowledge of community composition and variability between individuals, it does not provide the foundation for going beyond descriptive studies and toward truly predictive ecological models. In order to achieve this goal, we need longitudinal data of appropriate temporal and taxonomic resolution, so that established time series analysis tools for identifying and quantifying putative interactions among community members can be used. Here, we present new analyses of existing data to illustrate the potential usefulness of this approach. We discuss challenges related to sampling and data processing, as well as analytical approaches and considerations for future studies of the GI microbiota and other complex microbial systems.
Claw health and floor type in group housed sows.
Authors: Vermeer H. M. , Vermeij I. 
Published: August 2014

Abstract
The objective of this review is to give an overview of the effect of floor types on claw health in group housed sows. The risk on lameness caused by the pen floor is increasing with group housing becoming more important. Lameness is a major welfare and production problem and often related to claw lesions. A good-quality floor to ensure healthy claws is characterized by a surface with friction (non-slip), abrasion, soft and dry properties and rounded edges. During pregnancy, aggressive interactions should be minimized because the walking and activity characteristics are more important than in individual farrowing pens. During lactation, claws can recover from lesions in pregnancy and should heal before the start of a new reproductive cycle. Plastic-coated non-slippery floors are preferred during lactation. A rubber top layer is beneficial for pregnant sow claw health in the lying area and in part of the activity (slatted) area too. A combination of a good-quality floor and management measures minimizing aggressive interactions is a good basis for healthy claws in group housed sows.
Adolescent Substance use following Participation in a Universal Drug Prevention Program: Examining Relationships with Program Recall and Baseline use Status
Authors: Bavarian Niloofar , Duncan Robert , Lewis Kendra M. , Miao Alicia , Washburn Isaac J. 
Published: August 2014

Background The study examined whether adolescents receiving a universal, school based, drug prevention program in Grade 7 varied, by student profile, in substance use behaviors post program implementation. Profiles were a function of recall of program receipt and substance use at baseline. Methods A secondary analysis was conducted on data from the Adolescent Substance Abuse Prevention Study, a large, geographically diverse, longitudinal school-based cluster-randomized controlled trial of the Take Charge of Your Life drug prevention program. Profiles were created using self-reported substance use (preintervention) and program recall (postintervention) at Grade 7. First, characteristics of each of the 4 profiles of treatment students who varied by program recall and baseline substance use were explored. Then, multilevel logistic regression analyses were used to examine differences in the odds of substance use (alcohol, tobacco, and marijuana) among student profiles at the 6 additional study waves (Time 2 [Grade 7] through Time 7 [Grade 11]). Results Pearson's chi-square tests showed sample characteristics varied by student profile. Multilevel logistic regression results were consistent across all examined substance use behaviors at all time points. Namely, as compared with students who had no baseline substance use and had program recall (No Use, Recall), each of the remaining 3 profiles (No Use, No Recall; Use, Recall; Use, No Recall) were more likely to engage in substance use. Post hoc analyses showed that for the 2 subprofiles of baseline substance users, there were only 2 observed, and inconsistent, differences in the odds of subsequent substance use by recall status. Conclusions Findings suggest that for students who were not baseline substance users, program recall significantly decreased the likelihood of subsequent substance use. For students who were baseline substance users, program recall did not generally influence subsequent substance use. Implications for school-based drug prevention programs are discussed.

Published: August 2014

AbstractThe present study aimed to investigate motivations for the dual career of European student‐athletes living in countries providing different educational services for elite athletes: State‐centric regulation–State as sponsor/facilitator (State), National Sporting Federations/Institutes as intermediary (Federation) and Laisser Faire, no formal structures (No Structure). Therefore, the European Student‐athletes' Motivation towards Sports and Academics Questionnaire (SAMSAQ‐EU) was administered to 524 European student‐athletes. Exploratory Factor Analysis, and Confirmatory Factor Analysis were applied to test the factor structure, and the reliability and validity of the SAMSAQ‐EU, respectively. A multivariate approach was applied to verify subgroup effects (P ≤ 0.05) according to gender (i.e., female and male), age (i.e., ≤24 years, >24 years), type of sport (i.e., individual sport and team sport) and competition level (i.e., national and international). Insufficient confirmatory indexes were reported for the whole European student‐athlete group, whereas distinct three factor models [i.e., Student Athletic Motivation (SAM); Academic Motivation (AM); Career Athletic Motivation (CAM)] emerged, with acceptable reliability estimates, for State (SAM = 0.82; AM = 0.75; and CAM = 0.75), Federation (SAM = 0.82; AM = 0.66; and CAM = 0.87) and No Structure (SAM = 0.78; AM = 0.74; and CAM = 0.79) subgroups. Differences between subgroups were found only for competition level (P < 0.001) in relation to SAM (P = 0.001) and CAM (P < 0.001). For SAM, the highest and lowest values emerged for Federation (national, 5.1 ± 0.5; international, 5.4 ± 0.5) and State (national, 4.5 ± 0.9; international, 4.8 ± 0.7). The opposite picture emerged for CAM (Federation: national, 3.3 ± 0.7; international, 3.5 ± 0.9; State: national, 5.0 ± 0.8; international, 5.0 ± 0.9). Therefore, despite SAMSAQ‐EU demonstrated to be a useful tool, results showed that European student‐athletes' motivation for dual career has to be specifically investigated according to social contexts.

Published: August 2014

Abstract
Motivation: Sharing genomic data is crucial to support scientific investigation such as genome-wide association studies. However, recent investigations suggest the privacy of the individual participants in these studies can be compromised, leading to serious concerns and consequences, such as overly restricted access to data.
Results: We introduce a novel cryptographic strategy to securely perform meta-analysis for genetic association studies in large consortia. Our methodology is useful for supporting joint studies among disparate data sites, where privacy or confidentiality is of concern. We validate our method using three multisite association studies. Our research shows that genetic associations can be analyzed efficiently and accurately across substudy sites, without leaking information on individual participants and site-level association summaries.
Availability and implementation: Our software for secure meta-analysis of genetic association studies, SecureMA, is publicly available at http://github.com/XieConnect/SecureMA. Our customized secure computation framework is also publicly available at http://github.com/XieConnect/CircuitService

Visualization of protein sequence features using JavaScript and SVG with pViz.js
Authors: Mukhyala Kiran , Masselot Alexandre 
Published: August 2014

Abstract
Summary: pViz.js is a visualization library for displaying protein sequence features in a Web browser. By simply providing a sequence and the locations of its features, this lightweight, yet versatile, JavaScript library renders an interactive view of the protein features. Interactive exploration of protein sequence features over the Web is a common need in Bioinformatics. Although many Web sites have developed viewers to display these features, their implementations are usually focused on data from a specific source or use case. Some of these viewers can be adapted to fit other use cases but are not designed to be reusable. pViz makes it easy to display features as boxes aligned to a protein sequence with zooming functionality but also includes predefined renderings for secondary structure and post-translational modifications. The library is designed to further customize this view. We demonstrate such applications of pViz using two examples: a proteomic data visualization tool with an embedded viewer for displaying features on protein structure, and a tool to visualize the results of the variant_effect_predictor tool from Ensembl.
Availability and implementation: pViz.js is a JavaScript library, available on github at https://github.com/Genentech/pviz. This site includes examples and functional applications, installation instructions and usage documentation. A Readme file, which explains how to use pViz with examples, is available as Supplementary Material A.

Next-generation sequencing technologies: breaking the sound barrier of human genetics
Authors: Bahassi El Mustapha , Stambrook Peter J. 
Published: August 2014

Abstract
Demand for new technologies that deliver fast, inexpensive and accurate genome information has never been greater. This challenge has catalysed the rapid development of advances in next-generation sequencing (NGS). The generation of large volumes of sequence data and the speed of data acquisition are the primary advantages over previous, more standard methods. In 2013, the Food and Drug Administration granted marketing authorisation for the first high-throughput NG sequencer, Illumina’s MiSeqDx, which allowed the development and use of a large number of new genome-based tests. Here, we present a review of template preparation, nucleic acid sequencing and imaging, genome assembly and alignment approaches as well as recent advances in current and near-term commercially available NGS instruments. We also outline the broad range of applications for NGS technologies and provide guidelines for platform selection to best address biological questions of interest. DNA sequencing has revolutionised biological and medical research, and is poised to have a similar impact on the practice of medicine. This tool is but one of an increasing arsenal of developing tools that enhance our capabilities to identify, quantify and functionally characterise the components of biological networks that keep us healthy or make us sick. Despite advances in other ‘omic’ technologies, DNA sequencing and analysis, in many respects, have played the leading role to date. The new technologies provide a bridge between genotype and phenotype, both in man and model organisms, and have revolutionised how risk of developing a complex human disease may be assessed. The generation of large DNA sequence data sets is producing a wealth of medically relevant information on a large number of individuals and populations that will potentially form the basis of truly individualised medical care in the future.
