Salad = success and fries = failure? Conceptualizing and assessing self‐control outcome measures in food decision‐making research
Authors: Haws Kelly , Davis Scott , Dholakia Utpal 
Published: December 2015

AbstractResearchers studying decisions about food utilize a wide variety of measures to assess self‐control outcomes in experimental studies. However, it is often unclear whether or not the chosen dependent variables truly implicate self‐regulatory mechanisms in decision making. In the present research, we provide a conceptual framework for evaluating self‐control outcome measures, concentrating specifically on the domain of food and eating self‐control decisions. We propose and empirically examine the essential characteristics [i.e., (i) recognized as self‐control relevant by study population, (ii) related to individual differences in self‐control, and (iii) recognized as self‐control relevant by individual] of good self‐control outcome measures and provide specific methodological recommendations (including the “rank‐then‐choose” method) for capturing exhibited self‐control in the domain of food decision making. Our conceptual developments and recommendations seek to enhance the consistency, efficiency, and effectiveness of food‐related decision research. Copyright © 2015 John Wiley & Sons, Ltd.

Published: December 2015

AbstractIn vitro cell culture has provided a useful model to study the effects of oxygen on cellular behavior. However, it remains unknown whether the in vitro operations themselves affect the medium oxygen levels and the living states of cells. In addition, a prevailing controversy is whether reactive oxygen species (ROS) production is induced by continuous hypoxia or reoxygenation. In this study, we have measured the effects of different types of cell culture containers and the oxygen environment where medium replacement takes place on the actual oxygen tension in the medium. We found that the deviations of oxygen concentrations in the medium are much greater in 25‐cm2 flasks than in 24‐well plates and 35‐mm dishes. The dissolved oxygen concentrations in the medium were increased after medium replacement in normoxia, but remained unchanged in glove boxes in which the oxygen tension remained at a low level (11.4, 5.7, and 0.5% O2). We also found that medium replacement in normoxia increased the number of ROS‐positive cells and reduced the cell viability; meanwhile, medium replacement in a glove box did not produce the above effects. Therefore, we conclude that the use of 25‐cm2 flasks should be avoided and demonstrate that continuous hypoxia does not produce ROS, whereas the reoxygenation that occurs during the harvesting of cells leads to ROS and induces cell death.

ObjectivesThis observational study assessed the 9‐month clinical outcomes in an « all comers » population with a focus on patients with atrial fibrillation (AF) after thin strut bare metal stenting.BackgroundDrug eluting stent (DES) implantation is the treatment of choice for coronary artery disease (CAD) leaving only marginal indications for the use of bare metal stents (BMS). However, selected treatment populations with DES contraindications such as patients who cannot sustain 6–12 months of dual antiplatelet therapy (DAPT) remain candidates for BMS implantations.MethodsThin strut bare metal stenting ina prioridefined subgroups were investigated in a non‐randomized, international, multicenter «all comers» observational study. Primary endpoint was the 9‐month TLR rate whereas secondary endpoints included the 9‐month MACE and procedural success rates.ResultsA total of 783 patients of whom 98 patients had AF underwent BMS implantation. Patient age was 70.4 ± 12.8 years. Cardiovascular risk factors in the overall population were male gender (78.2%, 612/783), diabetes (25.2%, 197/783), hypertension (64.1%, 502/783), cardiogenic shock (4.9%, 38/783) and end stage renal disease (4.9%, 38/783). In‐hospital MACE was 4.1% (30/783) in the overall population. The 9‐month TLR rate was 4.5% (29/645) in the non‐AF group and 3.3% (3/90) in the AF group (P = 0.613). At 9 months, the MACE rate in the AF‐group and non‐AF group was not significantly different either (10.7%, 69/645 vs. 6.7%, 6/90;P = 0.237). Accumulated stroke rates were 0.3% (2/645) in the non‐AF subgroup at baseline and 1.1% (1/90) in the AF subgroup (P = 0.264).ConclusionBare metal stenting in AF patients delivered acceptably low TLR and MACE rates while having the benefit of a significantly shorter DAPT duration in a DES dominated clinical practice. © 2015 Wiley Periodicals, Inc.
Pressure Effects on Lignocellulose‐Degrading Enzymes
Authors: Kirsch Christian , Surendran Sruthi , Smirnova Irina 
Published: December 2015

AbstractThe effect of elevated pressure on the activity and stability of industrially relevant lignocellulose‐degrading enzymes and their mixtures was investigated. It was observed that even at moderate pressure the tested enzymes can be applied at higher temperature as at ambient pressure without significant activity loss. No negative influence of pressure on the enzyme stability was detected in the pressure range investigated. It can be concluded that pressure can improve the stability of lignocellulose‐digesting enzymes, enabling higher reaction temperatures and, therefore, higher reaction rates. This might be a useful tool in industrial applications of lignocellulose‐digesting enzymes.

Published: December 2015

AbstractAn enantioselective synthesis of an intermediate in the Tanino total synthesis of solanoeclepin A has been developed. The key step was an intramolecular [2+2] photocycloaddition, which led to the tricyclo[5.2.1.01, 6]decane core in six steps. The first photosubstrate, prepared through an indium‐mediated Barbier‐type reaction, gave an excellent [2+2] cycloaddition, but it could not be obtained in sufficient enantiopurity. The second photosubstrate, prepared through an asymmetric allene diborylation in high enantiomeric excess, gave the [2+2] cycloaddition product in high yield on irradiation at 365 nm on 20 g scale in a flow system. Other important steps were the replacement of a boronate group at the quaternary carbon by a vinyl group and diastereoselective cyclopropanation of an allylic alcohol.

Published: December 2015

AbstractIn process systems engineering models are used for many applications, e.g., process simulation, optimization or control. Various types of models such as shortcut or rigorous models exist. An exchange and reuse thereof is highly desirable, but seldom performed. This article focuses on current approaches for developing and solving process models in specific instances for different applications. A close look will be made at the state of the art in modeling, simulation, and optimization software. Requirements for future software developments are derived to reduce the development and synthesis costs for new chemical engineering processes. The web‐based modeling, simulation, and optimization environment MOSAIC is taken as an example to highlight current developments towards collaborative computer‐aided engineering work.

Published: December 2015

AbstractIn the past two decades, tremendous efforts have been made towards the development of synthetic strategies for nanostructured materials with well‐controlled size, shape, composition, and spatial arrangement. Herein, we report a systematic study on the synthesis of tellurium nanostructures, which can evolve from nanoparticles to nanorods, nanowires, and nanotubes by a simple solution‐based process. The size‐ and diameter‐dependent optical properties of Te nanowires have been explained based on the modeling calculations using the joint density of states (JDOS).

Published: December 2015

SummaryWith the rapid development of smartphones in recent years, we have witnessed an exponential growth of the number of mobile apps. Considering the security and management issues, network operators need to have a clear visibility into the apps running in the network. To this end, this paper presents a novel approach to generating the fingerprints for mobile apps from network traffic. The fingerprints that characterize the unique behaviors of specific mobile apps can be used to identify mobile apps from the real network traffic. In order to handle the large volume of traffic efficiently, we use non‐negative matrix factorization (NMF) to perform traffic analysis to cluster similar network traffic into groups. Then, access patterns of individual apps that are extracted from each group can be used as fingerprints distinguishing apps from others uniquely. The experimental evaluations show that the proposed approach can identify the mobile apps from random and mixed network traffic with high precision. Copyright © 2015 John Wiley & Sons, Ltd.
GPU‐based parallel fuzzy c‐mean clustering model via genetic algorithm
Authors: Hung Che‐Lun , Wu Yuan‐Huai 
Published: December 2015

SummaryDetection of white matter changes in brain tissue using magnetic resonance imaging has been an increasingly active and challenging research area in computational neuroscience. A genetic algorithm based on a fuzzy c‐mean clustering method (GAFCM) was applied to simulated images to separate foreground spot signal information from the background, and the results were compared. The strength of this algorithm was tested by evaluating the segmentation matching factor, coefficient of determination, concordance correlation, and gene expression values. The experimental results demonstrated that the segmentation ability of GAFCM was better than that of fuzzy c‐means and K‐means algorithms. However, GAFCM is computationally expensive. This study presents a new GPU‐based parallel GAFCM algorithm to improve the performance of GAFCM. The experimental results show that computational performance can be increased by a factor of approximately 20 over the CPU‐based GAFCM algorithm while maintaining the quality of the processed images. Thus, the proposed GPU‐based parallel GAFCM algorithm can achieve the same results and significantly decrease processing time. Copyright © 2015 John Wiley & Sons, Ltd.
First‐Principles Study on Doping of SnSe2 Monolayers
Authors: Huang YuCheng , Zhou Danmei , Chen Xi , Liu Hai , Wang Chan , Wang Sufan 
Published: December 2015

AbstractDoping is a vitally important technique that can be used to modulate the properties of two‐dimensional materials. In this work, by using first‐principles density functional calculations, we investigated the electrical properties of SnSe2 monolayers by p‐type/n‐type and isoelectronic doping. Substitution at Sn/Se sites was found to be easy if the monolayer was grown under Sn‐/Se‐poor conditions. Substitutions at Sn sites with metallic atoms (e.g. Ga, Ge, In, Bi, Sb, Pb) resulted in positive substitution energies, which indicated that they were not effective doping candidates. For substitutions at Se sites with nonmetallic atoms, no promising candidates were found for p‐type doping (e.g., N, P, As). Among these, N and As showed positive substitution energies. Although P had a negative substitution energy under Sn‐rich conditions, it introduced trap states within the band gap. For n‐type doping (e.g., F, Cl, Br), all the calculated substitution energies were negative under both Sn‐ and Se‐rich conditions. Br was proven to be a promising candidate, because the impurity introduced a shallow donor level. Finally, for isoelectronic doping (e.g., O, S, Te), the intrinsic semiconducting features of the SnSe2 monolayer did not change, and the contribution from the impurity to the states near the band edge increased with the atomic number.
Development of role‐differentiated bimanual manipulation in infancy: Part 1. The emergence of the skill
Authors: Babik Iryna , Michel George F. 
Published: December 2015

ABSTRACTThis is the first paper in a series of three discussing different aspects of the development of role‐differentiated bimanual manipulation (RDBM—two hands performing different but complementary actions on an object). Emergence of RDBM is an important shift in the development of infant manual skills. Trajectories of monthly changes in the number of RDBMs and RDBM hand preference were explored in a sample of 90 (57 males) normally developing infants (30 with a right preference for acquiring objects, 30 with a left preference, 30 with no preference) during the 9–14 month period. Multilevel analysis revealed that infants performed more RDBMs with age, with similar patterns of change in all hand preference groups. A hand‐use preference for RDBM became more prominent with age with most right‐preferring infants and those without a preference for object acquisition developing right‐hand preference for RDBM. Left‐preferring infants exhibited more heterogeneity in their hand‐use for RDBM. © 2015 Wiley Periodicals, Inc. Dev Psychobiol 58: 243–256, 2016.

Published: December 2015

AbstractCooperative behaviors are promoted by kin selection if the costs to the actor are smaller than the fitness benefits to the recipient, weighted by the coefficient of relatedness. In primates, cooperation occurs primarily among female dyads. Due to male dispersal before sexual maturity in many primate species, however, it is unknown whether there are sufficient opportunities for selective tolerance and occasional coalitionary support for kin selection to favor male nepotistic support. We studied the effect of the presence of male kin on correlates of male reproductive success (residence time, duration of high dominance rank) in non‐natal male long‐tailed macaques (Macaca fascicularis). We found that “related” (i.e., related at the half‐sibling level or higher) males in a group have a significantly higher probability to remain in the non‐natal group compared to males without relatives. Moreover, males stayed longer in a group when a relative was present at group entry or joined the same group within 3 months upon arrival. Males with co‐residing relatives also maintained a high rank for longer than those without. To our knowledge, this is the first demonstration of a potential nepotistic effect on residence and rank maintenance among non‐natal males in a social system without long‐term alliances.

Published: December 2015

AbstractThe hydration of haloalkynes to give α‐halomethyl ketones was achieved based on a combination of a Cu(OAc)2 catalyst and a TFA (trifluoroacetic acid) promoter. This is the first synthesis of chloro/bromo/iodo methyl ketones through a hydration reaction catalyzed by a recyclable catalytic system. The catalytic system has a wide substrate scope and excellent chemoselectivity, and the procedure can also be scaled up.
Investigation of Reactive Intermediates and Reaction Pathways in the Coupling Agent Mediated Phos­phonamidation Reaction
Authors: Fredriksen Kim Alex , Amedjkouh Mohamed 
Published: December 2015

AbstractThe preparation of carboxamides through the coupling agent mediated reaction of carboxylic acids and amines is one of the most frequently employed reaction types of modern organic synthesis and has largely replaced older methods of amide formation based on reactive acyl chloride intermediates. However, the preparations of analogous phosphonamidates still rely on the use of phosphonochloridate intermediates – a method that is incompatible with sensitive functional groups. Herein, we present a comprehensive study in which different coupling agents are tested in the phosphonamidation reaction. The procedures, parallel to those typically applied to the preparation of carboxamides, were generally unsuccessful with regard to the coupling reactions of monoesters of phosphonic acids and amines, with the exception of those mediated by (benzotriazol‐1‐yloxy)tripyrrolidinophosphonium hexafluorophosphate (PyBOP). The implementation of a preactivation period in the absence of the amine coupling partner allowed for efficient phosphonamidate formation with coupling agents such as (1‐cyano‐2‐ethyoxy‐2‐oxoethylideneaminooxy)dimethylamino‐morpholino‐carbenium hexafluorophosphate (COMU), [ethyl cyano(hydroxyimino)acetato‐O2]tri‐1‐pyrrolidinylphosphonium hexafluorophosphate (PyOxim), dicyclohexyl carbodiimide (DCC), N,N′‐diisopropylcarbodiimide (DIC), and N,N,N′,N′‐tetramethyl‐O‐(1H‐benzotriazol‐1‐yl)uronium hexafluorophosphate (HBTU). The reactive intermediates observed by 31P NMR analysis were individually synthesized and examined to understand their influence on the reaction.
Political involvement moderates the impact of worldviews and values on SDO and RWA
Authors: Leone Luigi , Livi Stefano , Chirumbolo Antonio 
Published: December 2015

AbstractThe Dual Process Model (DPM) of social attitudes and prejudice proposes that Social Dominance Orientation (SDO) and Right Wing Authoritarianism (RWA) reflect two distinct motivational processes. In two studies, we investigated how political involvement moderates the impact of social worldviews and value‐based dimensions on SDO and RWA. We proposed that political involvement constrains SDO, RWA and their antecedents into a tighter left–right ideological dimension, therefore transforming the double dissociation pattern of the DPM into a double additive pattern. As expected, for stronger political involvement, Study 1 (N = 237) showed that SDO and RWA were a function of both the competitive jungle and the dangerous world worldviews, whereas Study 2 (N = 143) pointed out that SDO and RWA were both connected with the value dimensions of self‐enhancement and conservation.

Published: December 2015

AbstractA novel Fe2O3 modified indium tin oxide electrode (Fe2O3/ITO) was fabricated by iron ion‐implantation method first, and then annealed at 300 °C. Fe2O3/ITO reveals good catalytic performance toward hydrogen peroxide (H2O2) in phosphate buffer solution due to the Fe(II)/Fe(III) redox couple. Amperometric response shows a linear dependency on the H2O2 concentration ranging up to 360 μM with a detection limit of 0.3 μM. Moreover, electrocatalytic activity based on rarely reported higher oxidation states of iron (tentatively assigned to Fe(IV)) was shown to allow the reliable detection of glucose and cysteine. The results show promising application potential of the proposed electrode.

Published: December 2015

AbstractThis study analyzed the electrical properties of a multiple‐cells using the electric cell‐substrate impedance sensing, a scalable three‐dimensional electrode array and an equivalent circuit model (ECM). The experimental results validated the accuracy and validity of the extraction method for the ECM. The ECM simulation results using the electrical properties extracted by measuring 52 HeLa cells successfully forecasted the impedance magnitudes and phases for 15, 29, 78, and 98 HeLa cells. Comparing the ECM simulations and measurements, the maximum average errors in magnitude and phase were 3.06 % and 4.67 %, suggesting the number of HeLa cells can be classified by their electrical properties.
Evaluation of the exact conditional spectrum and generalized conditional intensity measure methods for ground motion selection
Authors: Kwong N. Simon , Chopra Anil K. 
Published: December 2015

SummaryTwo existing, contemporary ground motion selection and modification procedures – (i) exact conditional spectrum (CS‐exact) and (ii) generalized conditional intensity measure (GCIM) – are evaluated in their ability to accurately estimate seismic demand hazard curves (SDHCs) of a given structure at a specified site. The amount of effort involved in implementing these procedures to compute a single SDHC is studied, and a case study is chosen where rigorous benchmark SDHCs can be determined for evaluation purposes. By comparing estimates from ground motion selection and modification procedures with the benchmark, we conclude that estimates from CS‐exact are unbiased in many of the cases considered. The estimates from GCIM are even more accurate, as they are unbiased for most – but not all – of the cases where estimates from CS‐exact are biased. We find that it is possible to obtain biased SDHCs from GCIM, even after employing a very diverse collection of intensity measures to select ground motions and implementing its bias‐checking feature, because it is usually difficult to identify intensity measures that are truly ‘sufficient’ for the response of a complex, multi‐degree‐of‐freedom system.
