Published: August 2017

AbstractObjectiveDepression symptoms are prevalent among breast cancer survivors (BCS). Reducing sedentary behavior (SED) may be a non‐pharmaceutical strategy for alleviating depression symptoms. However, little is known about SED among BCS. The present study aimed to: (i) describe SED behaviors among BCS and identify unique SED groups based on different SED dimensions; (ii) identify personal and cancer‐specific factors that discriminate SED clusters; and (iii) examine the association between SED clusters and depression symptoms.MethodsBaseline self‐report demographic and medical information was collected from 187 BCS. SED and physical activity were assessed over seven days using an accelerometer. Self‐reported depression symptoms were reported three months later. Multiple dimensions of SED were identified and examined in cluster analysis. The clusters were examined for differences using multivariate analysis of variance and chi‐square analyses. The difference in depression symptoms among SED groups was assessed using an analysis of covariance.ResultsHigh and low SED groups were identified. Survivors in the high SED cluster were significantly older, heavier, less physically active, reported less education, and were more likely to have undergone lymph/axial node dissection. Women in the high SED cluster reported significantly higher depression symptoms prospectively (M = 9.50, SD = 6.07) compared to women in the low SED group (M = 6.89, SD = 5.18), F(8,179) = 4.97, p = 0.03, R2 = 0.34.ConclusionsThe importance of understanding multiple dimensions of SED among BCS was highlighted. Reducing SED during the early survivorship period may alleviate depression symptoms.
Suppressing aflatoxin biosynthesis is not a breakthrough if not useful
Authors: Gressel Jonathan , Polturak Guy 
Published: August 2017

AbstractLiver‐affecting, carcinogenic aflatoxins produced by Aspergillus spp. are a major problem, especially in the humid developing world where storage conditions are often optimal for the fungi. Peanuts and maize have been transformed with RNAi constructs targeting Aspergillus flavus polyketide‐synthase, an early key enzyme in aflatoxin biosynthesis. Aflatoxin biosynthesis was suppressed in developing immature grain, less so in late maturing grain, and it is doubtful that the technology will be effective in near dry mature grain. The infected grain was still mouldy. As Aspergillus that infects grain preharvest can continue to grow and produce aflatoxin in poorly stored grain, and grain storage insects vector further infections, this technology seems to have little potential utility in the humid tropics. The biotechnological approaches of RNAi directly targeting Aspergillus, coupled with transgenic insecticidal proteins should be far more effective. These biotechnological approaches can be used in tandem with the RNAi against polyketide‐synthase, as well as with irradiation, biocontrol and better grain drying and hermetic dry storage in a controlled atmosphere. © 2017 Society of Chemical Industry
Influence of side stripe on the corrosion of unlacquered tinplate cans for food preserves
Authors: Montanari Angela , Zurlini Chiara 
Published: August 2017

Metal containers are used for packaging foodstuffs; more specifically, the cans used for preserving fruit have a plain body with side seam protected by a lacquer film.The traditionally used side stripe is adopted “out of abundance of caution”, as the tin present on the seam is removed by the welding process. Not using a side stripe would have practical/functional benefits for the entire production chain, with consequent reduction in the cost of the containers and in their environmental impact.Packaging of medium‐acidity products in tinplate cans is based on the principle of cathodic protection of steel by tin. To ensure that this condition persists throughout the product's shelf life, it is necessary for the anode area to be larger than the cathode area. When the seam is protected with lacquer, this condition is met. In cans where no side stripe is applied on the inner seam, the cathode area increases; this could lead to an increase in corrosion rate and consequent reduction of shelf life. However, the use of tinplate with high tin coating weight (D 11.2 g/m2) can limit this effect, under suitable packaging conditions (absence of oxygen).The aim of this study is to analyze the possibility of using cans without lacquer stripe on the electric side seam for the packaging of fruit and, more generally, of medium‐acidity products. Electrochemical measurements of model‐systems, and pack tests were used in the study.

Published: August 2017

RationaleMethylation protocols commonly call for acidic, hot conditions that are known to promote organic 1H/2H exchange in aromatic and aliphatic C–H bonds. Here we tested two such commonly used methods and compared a third that avoids these acidic conditions, to quantify isotope effects with each method and to directly determine acidic‐exchange rates relevant to experimental conditions.MethodsWe compared acidic and non‐acidic methylation approaches catalyzed by hydrochloric acid, acetyl chloride and EDCI (1‐ethyl‐3‐(3‐dimethylaminopropyl)carbodiimide)/DMAP (4‐dimethylaminopyridine), respectively. These were applied to two analytes: phthalic acid (an aromatic) and octacosanoic acid (an aliphatic). We analyzed yield by gas chromatography/flame ionization (GC/FID) and hydrogen and carbon isotopic compositions by isotope ratio mass spectrometry (GC/IRMS). We quantified the 1H/2H exchange rate on dimethyl phthalate under acidic conditions with proton nuclear magnetic resonance (1H‐NMR) measurements.ResultsThe δ2H and δ13C values and yield were equivalent among the three methods for methyl octacosanoate. The two acidic methods resulted in comparable yield and isotopic composition of dimethyl phthalate; however, the non‐acidic method resulted in lower δ2H and δ13C values perhaps due to low yields. Concerns over acid‐catalyzed 1H/2H exchange are unwarranted as the effect was trivial over a 12‐h reaction time.ConclusionsWe find product isolation yield and evaporation to be the main concerns in the accurate determination of isotopic composition. 1H/2H exchange reactions are too slow to cause measurable isotope fractionation over the typical duration and reaction conditions used in methylation. Thus, we are able to recommend continued use of acidic catalysts in such methylation reactions for both aliphatic and aromatic compounds.
Stabilization of switched affine systems with disturbed state‐dependent switching laws

Published: August 2017

SummaryIn this paper, we investigate the stabilization problem for a class of switched affine systems with a state‐dependent switching law. Since the states measurements are in general subject to perturbations and noises, we propose a robust switching‐law design method. Qualitative conditions for the stability of the closed‐loop switched system are given. Stability conditions are also formulated as Linear Matrix Inequalities (LMIs) to allow numerical implementations. Results are illustrated by numerical examples to show the efficiency of the method and its limits.

AbstractCamera traps typically generate large amounts of bycatch data of non‐target species that are secondary to the study's objectives. Bycatch data pooled from multiple studies can answer secondary research questions; however, variation in field and data management techniques creates problems when pooling data from multiple sources. Multi‐collaborator projects that use standardized methods to answer broad‐scale research questions are rare and limited in geographical scope. Many small, fixed‐term independent camera trap studies operate in poorly represented regions, often using field and data management methods tailored to their own objectives. Inconsistent data management practices lead to loss of bycatch data, or an inability to share it easily. As a case study to illustrate common problems that limit use of bycatch data, we discuss our experiences processing bycatch data obtained by multiple research groups during a range‐wide assessment of sun bears Helarctos malayanus in Southeast Asia. We found that the most significant barrier to using bycatch data for secondary research was the time required, by the owners of the data and by the secondary researchers (us), to retrieve, interpret and process data into a form suitable for secondary analyses. Furthermore, large quantities of data were lost due to incompleteness and ambiguities in data entry. From our experiences, and from a review of the published literature and online resources, we generated nine recommendations on data management best practices for field site metadata, camera trap deployment metadata, image classification data and derived data products. We cover simple techniques that can be employed without training, special software and Internet access, as well as options for more advanced users, including a review of data management software and platforms. From the range of solutions provided here, researchers can employ those that best suit their needs and capacity. Doing so will enhance the usefulness of their camera trap bycatch data by improving the ease of data sharing, enabling collaborations and expanding the scope of research.
Promoting Sustainability: Towards a Segmentation Model of Individual and Household Behaviour and Behaviour Change
Authors: Verplanken Bas 
Published: August 2017

AbstractBehaviours of individuals and households have major and cumulative impacts on the ecology and sustainable development. A generic segmentation model of sustainable behaviour is presented based on three fundamental drivers of behaviour: motivation, opportunity and habit. Four segments of consumers are distinguished: low motivation/low opportunity, high motivation/high opportunity, low motivation/high opportunity and high motivation/low opportunity. Strong unsustainable habits are likely to be found among low motivation/low opportunity consumers, while high motivation/high opportunity consumers have the propensity to adopt sustainable lifestyles and form strong sustainable habits. This model is then used to highlight how different intervention techniques may be effective for the different population segments. Traditional interventions to promote sustainable behaviours (e.g. goal setting, feedback), as well as alternative approaches, are discussed, including using habit discontinuities, mental models, choice architecture and systemic approaches. The model may thus form a starting point for selecting optimal behaviour change strategies in specific contexts. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment

Published: August 2017

AbstractFour binary co‐crystals with same molar ratio (1:1) were prepared by solvent evaporation method, involving 3‐(9‐Anthracenyl)‐1‐phenyl‐2‐propen‐1‐one (APPO), 1‐(4‐Methoxyphenyl)‐3‐(1‐pyrenyl)‐2‐Propen‐1‐one (MPPO), 3‐(9‐Anthracenyl)‐1‐(2‐thienyl)‐2‐Propen‐1‐one (ATPO), 1‐Acetyl‐3‐phenyl‐5‐(1‐pyrenyl)‐pyrazoline (APPP) as halogen acceptors and 1,4‐Diiodotetrafluorobenzene (1,4‐DITFB) as halogen donor. Crystal structure analysis reveals that the face‐to‐face pattern of 1,4‐DITFB and donors exist and C−I•••π, C−I•••O interactions mainly formed the crystal structure. X‐ray diffraction data, vibration spectroscopy, thermal behaviors, UV‐visible, absorption spectroscopy and fluorescence properties were exploited to investigate their structures and performance. Such properties are closely related to the delayed fluorescence emission induced by triple‐triple annihilation process. These results demonstrate that these crystals have potential research value in luminescent materials design.
GUICop: Approach and toolset for specification‐based GUI testing
Authors: Hammoud Dalal , Zaraket Fadi A. , Masri Wes 
Published: August 2017

SummaryOracles used for testing graphical user interface (GUI) programmes are required to take into consideration complicating factors such as variations in screen resolution or colour scheme when comparing observed GUI elements with expected GUI elements. Researchers proposed fuzzy comparison rules and computationally expensive image processing techniques to tame the comparison process because otherwise the naïve matching comparison would be too constraining and consequently impractical. Alternatively, this paper proposes GUICop, a novel approach with a supporting toolset that takes (1) a GUI programme and (2) user‐defined GUI specifications characterizing the rendering behaviour of the GUI elements and checks whether the execution traces of the programme satisfy the specifications. GUICop comprises the following: (1) a GUI Specification Language; (2) a Driver; (3) Instrumented GUI Libraries; 4) a Solver; and (5) a Code Weaver. The user defines the specifications of the subject GUI programme using the GUI Specification Language. The Driver traverses the GUI structure of the programme and generates events that drive its execution. The Instrumented GUI Libraries capture the GUI execution trace, ie, information about the positions and visibility of the GUI elements. And the Solver, enabled by code injected by the Code Weaver, checks whether the traces satisfy the specifications. GUICop was successfully evaluated using 4 open source GUI applications that included 8 defects, namely, Jajuk, Gason, JEdit, and TerpPaint.
Single cell transcriptomics of noncoding RNAs and their cell‐specificity
Authors: Gawronski Katerina A.B. , Kim Junhyong 
Published: August 2017

Recent developments of single cell transcriptome profiling methods have led to the realization that many seemingly homogeneous cells have surprising levels of expression variability. The biological implications of the high degree of variability is unclear but one possibility is that many genes are restricted in expression to small lineages of cells, suggesting the existence of many more cell types than previously estimated. Noncoding RNA (ncRNA) are thought to be key parts of gene regulatory processes and their single cell expression patterns may help to dissect the biological function of single cell variability. Technology for measuring ncRNA in single cell is still in development and most of the current single cell datasets have reliable measurements for only long noncoding RNA (lncRNA). Most works report that lncRNAs show lineage‐specific restricted expression patterns, which suggest that they might determine, at least in part, lineage fates and cell subtypes. However, evidence is still inconclusive as to whether lncRNAs and other ncRNAs are more lineage‐specific than protein‐coding genes. Nevertheless, measurement of ncRNAs in single cells will be important for studies of cell types and single cell function.

Short-day photoperiods affect expression of genes related to dormancy and freezing tolerance in Norway spruce seedlings
Authors: Wallin Elisabeth , Gräns Daniel , Jacobs Douglass F. , Lindström Anders , Verhoef Nathalie 
Published: August 2017

Abstract

Key Message

Gene expression analysis showed that prolonged short day (SD) treatment deepened dormancy and stimulated development of freezing tolerance ofPicea abiesseedlings. Prolonged SD treatment also caused later appearance of visible buds in autumn, reduced risks for reflushing, and promoted earlier spring bud break.

Context
Short day (SD) treatment of seedlings is a common practice in boreal forest tree nurseries to regulate shoot growth and prepare the seedlings for autumn planting or frozen storage.

Aims
The aim of this study was to examine responses of Norway spruce (Picea abies (L.) Karst.) to a range of SD treatments of different length and evaluate gene expression related to dormancy induction and development of freezing tolerance.

Methods
The seedlings were SD treated for 11 h a day during 7, 14, 21, or 28 days. Molecular tests were performed, and the expression profiles of dormancy and freezing tolerance-related genes were analyzed as well as determination of shoot growth, bud set, bud size, reflushing, dry matter content, and timing of spring bud break.

Results
The 7-day SD treatment was as effective as longer SD treatments in terminating apical shoot growth. However, short (7 days) SD treatment resulted in later activation of dormancy-related genes and of genes related to freezing tolerance compared to the longer treatments which had an impact on seedling phenology.

Conclusion
Gene expression analysis indicated an effective stimulus of dormancy-related genes when the SD treatment is prolonged for at least 1–2 weeks after shoot elongation has terminated and that seedlings thereafter are exposed to ambient outdoor climate conditions.
Ethnic differences in bullying victimization and psychological distress: A test of an ecological model☆

Published: August 2017

ABSTRACTThis study examines ethnic differences in the prevalence of bullying victimization by peers as well as the associations between bullying victimization and psychological distress with relevant ecological factors including parental supervision, school support, and community safety. The study utilized the 2011–2012 California Health Interview Survey (CHIS) Adolescents Data, which was collected in the United States using a multi‐stage stratified sampling design with a Random Digit‐Dial method. The final study sample contained a total of 2367 adolescents, comprised of 48.7% Whites, followed by 35.8% Latinos, 11.1% Asians, and 4.4% African Americans. About 49.3% were males with an overall mean age of 14.6 (sd = 1.7). Results showed that there were significant differences in rates of bullying victimization among the four surveyed ethnic subgroups of adolescents. Black adolescents reported the highest and Asian adolescents the lowest level of victimization. The results of the SEM test using the calibration sample revealed an adequate fit to the data (CFI = 0.95, RMSEA = 0.04, Δχ2/Δdf = 2.99). Separate model tests with the four subgroups of adolescents revealed good fits with the subsample data with the exception of the subsample of African Americans. Additionally, results show that factors associated with psychological distress vary widely among the White, Latino and Asian subgroups.
Do I fit in? Psychosocial ramifications of low gender typicality in early adolescence
Authors: Smith Danielle Sayre , Juvonen Jaana 
Published: August 2017

ABSTRACTThe current longitudinal study was designed to examine one of the possible underlying mechanisms that can help account for why low gender typicality (i.e., not feeling like a typical boy or girl) is related to subsequent psychosocial adjustment problems: peer victimization. Relying on a large (N = 5,991, 52% female), ethnically diverse U.S. sample, the results suggested that peer victimization at 7th grade partially accounts for associations between 7th grade gender typicality and 8th grade social anxiety, somatic complaints, and externalizing behavior, when controlling for earlier (e.g., 6th grade) levels of adjustment. Associations were similar across ethnic groups. Peer victimization mediated associations for boys and girls across all outcomes; however, girls showed stronger associations with somatic complaints and boys showed stronger associations with externalizing behavior. These results suggest that attempts to improve adjustment for youth feeling low gender typicality should focus in part on reducing peer victimization.

Published: August 2017

AbstractPulmonary vein isolation is an effective treatment for patients with atrial fibrillation (AF).Although vasospastic angina (VSA) is not a common complication after ablation of AF, we report 3 cases of VSA following ablation of persistent AF. Two of the 3 patients felt chest pain following pulmonary vein isolation, and complex fractionated atrial electrogram ablations were performed. ST elevation in the inferior leads and atrioventricular block occurred because of severe coronary vasospasm. In the third patient, the electrocardiography monitor detected transient ST elevation within an hour after ablation. Treatment of VSA may be required following catheter ablation of AF.
