Authors: Crutcher Bryan , Moran Ryan N. , Covassin Tracey 
Published: June 2018

Context:Although social support has been reported to be a factor that increases retention of athletic trainers in their profession, there is a lack of literature examining the specific relationship of social support satisfaction and its predictive influence on stress and depression among athletic training students.Objective:To determine which sources of social support were perceived to be the most salient and ascertain whether social support satisfaction can predict stress and depression among athletic training students.Design:Cross-sectional study.Setting:Nine Commission on Accreditation of Athletic Training Education–accredited professional athletic training programs.Patients or Other Participants:A total of 204 athletic training students from Commission on Accreditation of Athletic Training Education–accredited athletic training programs were included in this study.Main Outcome Measure(s):Participants completed the Perceived Stress Scale, Center for Epidemiologic Studies Depression Scale, and the Social Support Questionnaire.Results:Social Support Satisfaction significantly predicted overall perceived stress (P = .010) and depression (P &lt; .001). Satisfaction of support from family (P = .043) and other athletic trainers (P = .011) were significant predictors of perceived stress, whereas satisfaction of support from family (P = .003), other athletic trainers (P = .002), and athletes (P = .038) significantly predicted depression.Conclusions:The current study suggests that having an increased satisfaction of social support may reduce stress perceptions and depression in athletic training students.

Mentee participants recognized the program gave them a chance to gain an external perspective and advance their research agendas, while mentors learned from their mentees and were able to use the program as a means to gain professional service.
An improved logistic regression model based on a spatially weighted technique (ILRBSWT v1.0) and its application to mineral prospectivity mapping
Authors: Zhang Daojun , Ren Na , Hou Xianhui 
Published: June 2018

Abstract. The combination of
complex, multiple minerogenic stages and mineral superposition during
geological processes has resulted in dynamic spatial distributions and
nonstationarity of geological variables. For example, geochemical elements
exhibit clear spatial variability and trends with coverage type changes.
Thus, bias is likely to occur under these conditions when general regression
models are applied to mineral prospectivity mapping (MPM). In this study, we
used a spatially weighted technique to improve general logistic regression
and developed an improved model, i.e., the improved logistic regression
model, based on a spatially weighted technique (ILRBSWT, version 1.0). The
capabilities and advantages of ILRBSWT are as follows: (1) it is a
geographically weighted regression (GWR) model, and thus it has all
advantages of GWR when managing spatial trends and nonstationarity; (2) while
the current software employed for GWR mainly applies linear regression,
ILRBSWT is based on logistic regression, which is more suitable for MPM
because mineralization is a binary event; (3) a missing data processing
method borrowed from weights of evidence is included in ILRBSWT to extend its
adaptability when managing multisource data; and (4) in addition to
geographical distance, the differences in data quality or exploration level
can be weighted in the new model.

USING STATISTICAL TOOLS TO DETECT GASOLINE ADULTERATION
Authors: Barbeira Paulo Jorge Sanches 
Published: June 2018

Histograms and normal distribution curves (Gaussian fit) were used to determine the average composition of the gasoline commercialized in the state of Minas Gerais, Brazil, and to detect samples with atypical composition. Atypical composition may rise from the fact that the gasoline comes from distinct sources (refinery or petrochemical plant) or may be due to the careful addition of industrial solvents. A considerable number of samples of atypical composition have been detected despite the samples tested having the same source. This statistical analytical tool has been shown useful in the evaluation of fuel quality.

Authors: Campigotto Angelica , Leahy Stephane , Choudhury Ayan , Zhao Guowei , Lai Yongjun 
Published: June 2018

A novel, inexpensive, and easy-to-use strain sensor using polydimethylsiloxane (PDMS) was developed. The sensor consists of a microchannel that is partially filled with a coloured liquid and embedded in a piece of PDMS. A finite element model was developed to optimize the geometry of the microchannel to achieve higher sensitivity. The highest gauge factor that was measured experimentally was 41. The gauge factor was affected by the microchannel’s square cross-sectional area, the number of basic units in the microchannel, and the inlet and outlet configuration. As a case study, the developed strain sensors were used to measure the rotation angle of the wrist and finger joints.

Authors: Roques Patricia , Roux Dominique 
Published: June 2018

Dans un contexte d’incitation à la réduction énergétique, quels sont les leviers d’action sur les comportements de consommation des individus, au-delà des valeurs qu’ils associent à la maîtrise de leur consommation ? Sur la base d’une étude qualitative menée avec 40 répondants d’un même complexe locatif réhabilité, cette recherche mobilise la théorie des pratiques appliquée au contexte de la consommation énergétique. Après avoir présenté et discuté ce cadre d’analyse peu usité en marketing, elle propose une typologie de profils. Ceux-ci intègrent à la fois les savoir-faire, les routines et les significations attachées à un ensemble d’activités consommatrices d’énergie, mais aussi le système d’équipement incorporé au logement et les incitations/prescriptions qui ont accompagné le programme de réhabilitation énergétique. Les résultats enrichissent les approches comportementales par la prise en compte de l’environnement socio-technique des individus et fournissent une série de recommandations utiles aux bailleurs sociaux comme aux organisations publiques ou marchandes engagées dans ces problématiques.
Short Report: Impact of Sleep Disorders on Depression and Patient-Perceived Health-Related Quality of Life in Multiple Sclerosis
Authors: White Emily K. , Sullivan Amy B. , Drerup Michelle 
Published: June 2018

Abstract

Background:
Sleep disorders in multiple sclerosis (MS) are associated with reduced health-related quality of life (HRQOL) and depression. However, research investigating and comparing how the two most common sleep disorders—insomnia and obstructive sleep apnea (OSA)—affect depression and HRQOL in MS is limited. The goal of this study is to examine the impact of diagnosed sleep disorders on patient-reported 1) HRQOL and 2) depressive symptoms in patients with MS.

Methods:
We performed a retrospective medical record review of 531 adult patients with MS: 287 (54%) with a comorbid sleep disorder (insomnia or OSA) and 244 (46%) without a diagnosed sleep disorder.

Results:
Neither 1) average ratings of depression or HRQOL nor 2) the proportion of moderate depression or moderately impaired HRQOL differed between individuals with MS and insomnia and those with MS and OSA. Neither sleep disorder predicted increased depression or poorer HRQOL. However, individuals with MS and a comorbid sleep disorder (insomnia or OSA) had poorer HRQOL compared with those without a diagnosed sleep disorder (MS only).

Conclusions:
Presence of a diagnosed sleep disorder may negatively affect HRQOL in MS. Providers should continue to screen for sleep disorders given their negative impact on patients with MS and the availability of effective treatments for insomnia and OSA.
Sample Preparation and Quantitative Analysis for PowderX‐Ray Diffractometry
Authors: Ohbuchi Atsushi , Nakamura Toshihiro 
Published: June 2018

AbstractPowder X‐ray diffractometry (PXRD) is widely used for various material analysis, including powders, thin films, and bulk samples. Some optics configurations are used for powder X‐ray diffractometer; Kα1optics can be used as high‐end laboratory system. Semiconductor detectors can enable high‐speed measurements, suppress increased background noise from X‐ray fluorescence, and allow two‐dimensional diffraction‐image measurement. For obtaining reproducible diffraction data, sample preparation and particle size of powder sample are very important factors. Several quantitative analysis methods are applied to calculate quantitative values of crystalline phases, such as calibrating method, internal standard method, standard addition method, RIR (reference intensity ratio) method, and the Rietveld refinement. In the Rietveld refinement, amorphous phase can be calculated using internal standard material. Measurement data for the Rietveld refinement can be obtained in short time using semiconductor detectors. Sample preparation of powder sample and quantitative analysis method are described in this article.
Methods Applied for the Allosteric Site Revelation

Published: June 2018

Abstract
Allostery is the functional change at one site on a protein due to alterations at a distant site. Allosteric modulators by targeting allosteric site can fine‐tune protein's activity. Drugging allosteric sites has therefore been regarded as a novel direction in drug discovery. However, identification of allosteric sites by experimental approaches is serendipitous. Since bioinformatics and structural biology develop rapidly, protein dynamics and structures can be better understood and allosteric drug discovery is on the cusp of a novel era of rational computational methodologies. Various computational allosteric site prediction models have therefore been put forward. Computational prediction is helpful for exploration of potential allosteric sites due to its higher accuracy and relatively shorter timescale. Here, we review the state‐of‐the‐art computational allosteric sites prediction methods. We first classify different approaches according to their underlying theoretical models, then algorithms and fundamental theories behind them are revealed, and finally successful examples are presented. We put forward the current challenges faced by these approaches. Possible solutions are provided with the latest advances in the field of computational biology, and tactics to resolve these demanding tasks are also discussed.

AbstractDevelopment of flexible and freestanding electrode is attracting great attention in lithium–sulfur (Li–S) batteries, but the severe capacity fading caused by the lithium polysulfides (PSs) shuttle effect remains challenging. Herein, a completely new polymeric binder of polyethersulfone is introduced. Not only it enables massive production of flexible/current‐free electrode by a novel concept of “phase‐inversion” approach but also the resultant polymeric networks can effectively trap the soluble polysulfides within the electrode, owing to the higher hydrophilicity and stronger affinity properties than the routine polyvinylidene fluoride. Coupling with polysulfide‐based electrolyte, the Li–S cell shows a higher capacity of 1141 mAh g−1, a lower polarization of 192 mV, and a more stable capacity retention with 100% Coulombic efficiency over 100 cycles at 0.25C. The advantages of favored binder and electrolyte are further demonstrated in lithium‐ion sulfur full battery with lithiated graphite anode, which demonstrates much improved performance than those previously reported. This work not only introduces a novel strategy for flexible freestanding electrodes but also enlightens the importance of coupling electrodes and electrolytes to higher performances for Li–S battery.

Published: June 2018

AbstractIn this work, an environmentally friendly and novel oxide‐based mechanoluminescent material, Sr3Al2O6: Eu3+, which can serve as the alternative for the widely used but environmentally hazardous transition metal–doped sulfides is reported. This oxide could exhibit highly efficient photoluminescence, but even more efficient mechanoluminescence as embedded into polydimethylsiloxane matrix under mechanical stimulation. The emitting color of the resultant Sr3Al2O6: Eu3+/polydimethylsiloxane elastomer composites could be further manipulated by adjusting the synthesis atmosphere of the Sr3Al2O6: Eu3+ based on its unique self‐reduction characteristic. Moreover, by combining the wavelength selectivity of photoluminescence and dynamic stress response of mechanoluminescence, Sr3Al2O6: Eu3+ enables the design of two types of intriguing devices. They are a dual‐responsive anticounterfeiting flexible device activated by either photons or mechanics, and a comprehensive stretching/strain sensor capable of sensing both strain level and stretching states. In comparison to the conventional luminescent materials, with a rare combination of efficient photoluminescence, highly sensitive mechanoluminescence, and facile color tunability, Sr3Al2O6: Eu3+ is much more versatile and ideal for various advanced applications.

AbstractDiscovering materials that exhibit zero linear compressibility (ZLC) behavior under hydrostatic pressure is extremely difficult. To date, only a handful of ZLC materials have been found, and almost all of them are ultrahard materials with densified structures. Here, to explore ZLC in nondense materials, a structural model analogous to the structure of the “Lu‐Ban stool,” a product of traditional Chinese woodworking invented 2500 years ago, is proposed. The application of this model to borates leads to the discovery of ZLC in AEB2O4 (AE = Ca and Sr) with the unique “Lu‐Ban stool”‐like structure, which can obtain a subtle mechanical balance between pressure‐induced expansion and contraction effects. Coupled with the very wide ultraviolet transparent windows, the ZLC behavior of AEB2O4 may result in some unique but important applications. The applications of the “Lu‐Ban stool” model open a new route for pursuing ZLC materials in nondense structural systems.

AbstractSurface‐bound microarrays of multiple oligo‐ and macromolecules (e.g., peptides, DNA) offer versatile options in biomedical applications like drug screening, DNA analysis, or medical diagnostics. Combinatorial syntheses of these molecules in situ can save significant resources in regard to processing time and material use. Furthermore, high feature densities are needed to enable high‐throughput and low sample volumes as generally regarded in combinatorial chemistry. Here, a scanning‐probe‐lithography‐based approach for the combinatorial in situ synthesis of macromolecules is presented in microarray format. Feature sizes below 40 µm allow for the creation of high‐density arrays with feature densities of 62 500 features per cm2. To demonstrate feasibility of this approach for biomedical applications, a multiplexed array of functional protein tags (HA‐ and FLAG‐tag) is synthesized, and selective binding of respective epitope recognizing antibodies is shown. This approach uses only small amounts of base chemicals for synthesis and can be further parallelized, therefore, opening up a route to flexible, highly dense, and cost‐effective microarrays.

AbstractPeriodically hydrogenated graphene is predicted to form new kinds of crystalline 2D materials such as graphane, graphone, and 2D CxHy, which exhibit unique electronic properties. Controlled synthesis of periodically hydrogenated graphene is needed for fundamental research and possible electronic applications. Only small patches of such materials have been grown so far, while the experimental fabrication of large‐scale, periodically hydrogenated graphene has remained challenging. In the present work, large‐scale, periodically hydrogenated graphene is fabricated on Ru(0001). The as‐fabricated hydrogenated graphene is highly ordered, with a √3 × √3/R30° period relative to the pristine graphene. As the ratio of hydrogen and carbon is 1:3, the periodically hydrogenated graphene is named “one‐third‐hydrogenated graphene” (OTHG). The area of OTHG is up to 16 mm2. Density functional theory calculations demonstrate that the OTHG has two deformed Dirac cones along one high‐symmetry direction and a finite energy gap along the other directions at the Fermi energy, indicating strong anisotropic electrical properties. An efficient method is thus provided to produce large‐scale crystalline functionalized graphene with specially desired properties.
