Authors: Ju Yun Yong , Hong Won G. , Choi Nak-Jin , Hoon Kim Byung , Jun Yongseok , Lee Hyung-Kun 
Published: June 2015

AbstractElectric components based on fibers or textiles have been investigated owing to their potential applications in wearable devices. High performance on response to gas, drape-ability and washing durability are of important for gas sensors based on fiber substrates. In this report, we demonstrate the bendable and washable electronic textile (e-textile) gas sensors composed of reduced graphene oxides (RGOs) using commercially available yarn and molecular glue through an electrostatic self-assembly. The e-textile gas sensor possesses chemical durability to several detergent washing treatments and mechanical stability under 1,000 bending tests at an extreme bending radius of 1 mm as well as a high response to NO2 gas at room temperature with selectivity to other gases such as acetone, ethanol, ethylene and CO2.

Authors: Li Yuchao , Xin Hongbao , Liu Xiaoshuai , Li Baojun 
Published: June 2015

AbstractNon-contact intracellular binding and controllable manipulation of chloroplasts in vivo was demonstrated using an optical fiber probe. Launching a 980-nm laser beam into a fiber, which was placed about 3 μm above the surface of a living plant (Hydrilla verticillata) leaf, enabled stable binding of different numbers of chloroplasts, as well as their arrangement into one-dimensional chains and two-dimensional arrays inside the leaf without damaging the chloroplasts. Additionally, the formed chloroplast chains were controllably transported inside the living cells. The optical force exerted on the chloroplasts was calculated to explain the experimental results. This method provides a flexible method for studying intracellular organelle interaction with highly organized organelle-organelle contact in vivo in a non-contact manner.

AbstractThe xeroderma pigmentosum group C (XPC) protein complex is a key factor that detects DNA damage and initiates nucleotide excision repair (NER) in mammalian cells. Although biochemical and structural studies have elucidated the interaction of XPC with damaged DNA, the mechanism of its regulation in vivo remains to be understood in more details. Here, we show that the XPC protein undergoes modification by small ubiquitin-related modifier (SUMO) proteins and the lack of this modification compromises the repair of UV-induced DNA photolesions. In the absence of SUMOylation, XPC is normally recruited to the sites with photolesions, but then immobilized profoundly by the UV-damaged DNA-binding protein (UV-DDB) complex. Since the absence of UV-DDB alleviates the NER defect caused by impaired SUMOylation of XPC, we propose that this modification is critical for functional interactions of XPC with UV-DDB, which facilitate the efficient damage handover between the two damage recognition factors and subsequent initiation of NER.
Investigation and simulation of photonic crystal directional coupler switch
Authors: Maktoobi Sh. , Bahadori‐Haghighi Sh. 
Published: June 2015

The photonic crystal optical switch is one of the most important applications of photonic crystals in telecommunication networks. Switching is a main process in digital computers and signal processing systems. The growth of optical signal processing systems draws particular attention to the design of ultra‐fast optical switches. In this reported work, first a directional coupler switch based on photonic crystals is designed and the linear state has been analysed and simulated. Then, the principles of nonlinear optics are used to perform optical switching at a wavelength of 1550 nm by COMSOL Multiphysics in micron dimension. The dielectric rods of this photonic crystal lattice are made of AlGaAs. The central row is an important factor for attaining the required power in nonlinear switching performance. Finally, the radius of rods in the central nonlinear row is changed several times and the results are compared with each other. In this switch, the output power ratio, called the extinction ratio, and the required refractive index change for the nonlinear status are taken into account. The former is for the evaluation of directional coupler efficiency and the latter is generally an important factor in optical nonlinear switches.
Single‐stage fully recycling folded cascode OTA for switched‐capacitor circuits
Authors: Akbari M. 
Published: June 2015

A single‐stage multi‐path operational transconductance amplifier (OTA) is presented. The proposed amplifier uses the transconductance enhancing technique in an upgraded folded cascode (FC) amplifier. It significantly improves the DC gain, unity‐gain bandwidth and slew rate compared with previous FC amplifiers with the same power consumption. Simulation results in 90 nm complementary metal‐oxide semiconductor (CMOS) technology show that the proposed OTA achieves a 59.1 dB DC gain and a gain bandwidth of 650 MHz, which makes it suitable for fast‐settling switched‐capacitor circuits.
Some new surprises in chaos
Authors: Bunimovich Leonid A. , Vela-Arevalo Luz V. 
Published: June 2015

“Chaos is found in greatest abundance wherever order is being sought. It always defeats order, because it is better organized” Terry Pratchett
A brief review is presented of some recent findings in the theory of chaotic dynamics. We also prove a statement that could be naturally considered as a dual one to the Poincaré theorem on recurrences. Numerical results demonstrate that some parts of the phase space of chaotic systems are more likely to be visited earlier than other parts. A new class of chaotic focusing billiards is discussed that clearly violates the main condition considered to be necessary for chaos in focusing billiards.

Published: June 2015

Abstract
New research techniques and changing Muskellunge Esox masquinongy and Northern Pike E. lucius fisheries have contributed to paradigm shifts in the science and management of these species. A symposium on Muskellunge and Northern Pike biology, ecology and management was held at the American Fisheries Society Annual Meeting in Little Rock, Arkansas, and a panel discussion following the symposium identified several research and management priorities, including spawning habitat identification, habitat and population restoration, genetics, and selective mortality and exploitation. Future Muskellunge and Northern Pike research should focus on quantifying egg and age-0 survival based on habitat characteristics, rigorously evaluating habitat restoration efforts using statistically sound study designs, describing range-wide genetic structure of populations, and developing a better understanding of how selective mortality and exploitation can alter population size structure, sex ratios, and life history characteristics. Information and outcomes from the proposed research and management priorities will be critical for conserving and restoring self-sustaining populations of Muskellunge and Northern Pike.

Incoherent Texts? Storytelling, Preaching, and theCent nouvelles nouvellesin Marguerite de Navarre’sHeptaméron21*
Authors: Ridder-Vignone António De 
Published: June 2015

AbstractTo analyze Marguerite de Navarre’s response to the misogynist francophone novella tradition, this article asks how material provided by oldernouvellesis reorganized in theHeptaméron, blurring both normative definitions of masculinity and femininity and the lines between framed novellas and other genres. This article describes Marguerite’s use of nonfictional sources as well asCent nouvelles nouvelles26. Visual iconographic transformations in theCent nouvelles nouvellesare converted in theHeptaméroninto textual and intergeneric transformations. In the distance betweenCent nouvelles nouvelles26’s elaborate crossdressing farce andHeptaméron21, which blends romance, pardon request, and martyr’s tale, one perceives the differences in gendered thought and rhetorical strategy separating Marguerite from her anonymous predecessors.
The Homeric Question in the Sixteenth Century: Early Modern Scholarship and the Text of Homer*
Authors: Demetriou Tania 
Published: June 2015

AbstractGerard Falkenburg’s annotations on Homer reveal a type of philology rare in the Renaissance: Falkenburg probed the epics’ histories by analyzing their textual fault lines, as F. A. Wolf would do in 1795 when he revolutionized the study of Homer. Following in the footsteps of certain other scholars, Falkenburg alone arrived at a methodology for this sort of work, without publishing his observations. Obertus Giphanius did use them liberally in his 1572 commentary on Homer and his short preface to this is often noted as a mysterious forerunner to the Homeric Question. But if this previously unnoticed scholarship contextualizes famous early modern insights on the Homeric Question like Giphanius’s, one important reason it was not taken further lies with Giphanius’s flawed grasp and transmission of the technical innovations in Falkenburg’s work.
A web application for the unspecific detection of differentially expressed DNA regions in strand-specific expression data

Published: June 2015

Abstract
Genomic technologies allow laboratories to produce large-scale data sets, either through the use of next-generation sequencing or microarray platforms. To explore these data sets and obtain maximum value from the data, researchers view their results alongside all the known features of a given reference genome. To study transcriptional changes that occur under a given condition, researchers search for regions of the genome that are differentially expressed between different experimental conditions. In order to identify these regions several algorithms have been developed over the years, along with some bioinformatic platforms that enable their use. However, currently available applications for comparative microarray analysis exclusively focus on changes in gene expression within known transcribed regions of predicted protein-coding genes, the changes that occur in non-predictable genetic elements, such as non-coding RNAs. Here, we present a web application for the visualization of strand-specific tiling microarray or next-generation sequencing data that allows customized detection of differentially expressed regions all along the genome in an unspecific manner, that allows identification of all RNA sequences, predictable or not.

The projack: a resampling approach to correct for ranking bias in high-throughput studies
Authors: Zhou Yi-Hui , Wright Fred A. 
Published: June 2015

Abstract
The problem of ranked inference arises in a number of settings, for which the investigator wishes to perform parameter inference after ordering a set of $m$ statistics. In contrast to inference for a single hypothesis, the ranking procedure introduces considerable bias, a problem known as the “winner's curse” in genetic association. We introduce the projack (for Prediction by Re- Ordered Jackknife and Cross-Validation, $K$-fold). The projack is a resampling-based procedure that provides low-bias estimates of the expected ranked effect size parameter for a set of possibly correlated $z$ statistics. The approach is flexible, and has wide applicability to high-dimensional datasets, including those arising from genomics platforms. Initially, motivated for the setting where original data are available for resampling, the projack can be extended to the situation where only the vector of $z$ values is available. We illustrate the projack for correction of the winner's curse in genetic association, although it can be used much more generally.
Quantile regression in the presence of monotone missingness with sensitivity analysis
Authors: Liu Minzhao , Daniels Michael J. , Perri Michael G. 
Published: June 2015

AbstractIn this paper, we develop methods for longitudinal quantile regression when there is monotone missingness. In particular, we propose pattern mixture models with a constraint that provides a straightforward interpretation of the marginal quantile regression parameters. Our approach allows sensitivity analysis which is an essential component in inference for incomplete data. To facilitate computation of the likelihood, we propose a novel way to obtain analytic forms for the required integrals. We conduct simulations to examine the robustness of our approach to modeling assumptions and compare its performance to competing approaches. The model is applied to data from a recent clinical trial on weight management.
Variable selection for modeling the absolute magnitude at maximum of Type Ia supernovae
Authors: Uemura Makoto , Kawabata Koji S. , Ikeda Shiro , Maeda Keiichi 
Published: June 2015

AbstractWe discuss what is an appropriate set of explanatory variables in order to predict the absolute magnitude at the maximum of Type Ia supernovae. In order to have a good prediction, the error for future data, which is called the “generalization error,” should be small. We use cross-validation in order to control the generalization error and a LASSO-type estimator in order to choose the set of variables. This approach can be used even in the case that the number of samples is smaller than the number of candidate variables. We studied the Berkeley supernova database with our approach. Candidates for the explanatory variables include normalized spectral data, variables about lines, and previously proposed flux ratios, as well as the color and light-curve widths. As a result, we confirmed the past understanding about Type Ia supernovae: (i) The absolute magnitude at maximum depends on the color and light-curve width. (ii) The light-curve width depends on the strength of Si ii. Recent studies have suggested adding more variables in order to explain the absolute magnitude. However, our analysis does not support adding any other variables in order to have a better generalization error.
Metal enrichment in the Fermi bubbles as a probe of their origin
Authors: Inoue Yoshiyuki , Nakashima Shinya , Tahara Masaya , Kataoka Jun , Totani Tomonori , Fujita Yutaka , Sofue Yoshiaki 
Published: June 2015

Abstract
The Fermi bubbles are gigantic gamma-ray structures in our Galaxy. The physical origin of the bubbles is still under debate. The leading scenarios can be divided into two categories. One is nuclear star-forming activity similar to extragalactic starburst galaxies and the other is past active galactic nucleus (AGN)-like activity of the Galactic center supermassive black hole. In this letter, we propose that metal abundance measurements will provide an important clue to probe their origin. Based on a simple spherically symmetric bubble model, we find that the generated metallicity and abundance patterns of the bubbles’ gas strongly depend on assumed star formation or AGN activities. Star formation scenarios predict higher metallicities and abundance ratios of [O/Fe] and [Ne/Fe] than AGN scenarios do because of supernovae ejecta. Furthermore, the resultant abundance depends on the gamma-ray emission process because different mass injection histories are required for the different gamma-ray emission processes due to the acceleration and cooling time scales of non-thermal particles. Future X-ray missions such as ASTRO-H and Athena will give a clue to probe the origin of the bubbles through abundance measurements with their high energy resolution instruments.
Cosmological constraints from Subaru weak lensing cluster counts
Authors: Hamana Takashi , Sakurai Junya , Koike Michitaro , Miller Lance 
Published: June 2015

Abstract
We present results of weak lensing cluster counts obtained from 11-degree2 Subaru/SuprimeCam data. Although the area is much smaller than previous work dealing with weak lensing peak statistics, the number density of galaxies usable for weak lensing analysis is about twice as large. The higher galaxy number density reduces the noise in the weak lensing mass maps, and thus increases the signal-to-noise ratio (S/N) of peaks of the lensing signal due to massive clusters. This enables us to construct a weak lensing selected cluster sample by adopting a high threshold S/N, such that the contamination rate due to false signals is small. We find six peaks with S/N &gt; 5. For all the peaks, previously identified clusters of galaxies are matched within a separation of 1′, demonstrating good correspondence between the peaks and clusters of galaxies. We evaluate the statistical error in the weak lensing cluster counts using mock weak lensing data generated from full-sky ray-tracing simulations, and find Npeak = 6 ± 3.1 in an effective area of 9.0 degree2. We compare the measured weak lensing cluster counts with the theoretical model prediction based on halo models and place the constraint on the Ωm–σ8 plane which is found to be consistent with currently standard ΛCDM models. It is demonstrated that the weak lensing cluster counts can place a unique constraint on the σ8–c0 plane, where c0 is the normalization of the dark matter halo mass–concentration relationship. Finally we discuss prospects for ongoing/future wide field optical galaxy surveys.
A Perioperative Course of Gabapentin Does Not Produce a Clinically Meaningful Improvement in Analgesia after Cesarean Delivery
Authors: Monks David T. , Hoppe David W. , Downey Kristi , Shah Vibhuti , Bernstein Paul , Carvalho Jose C. A. 
Published: June 2015

AbstractAbstract
In 197 women randomized to receive gabapentin, 600 mg before cesarean delivery and 200 mg every 8 h for 2 days postoperatively or placebo, there was a statistically significant but clinically unimportant difference in pain with movement 24 h after surgery. Sedation was greater in women treated with gabapentin.

Background:
Studies examining the efficacy of a single preoperative dose of gabapentin for analgesia after cesarean delivery (CD) have been inconclusive. The authors hypothesized that a perioperative course of gabapentin would improve analgesia after CD.

Methods:
This single-center, randomized, double-blind, placebo-controlled, parallel-group, superiority trial was designed to determine the analgesic efficacy of a perioperative course of gabapentin when added to a multimodal analgesic regimen. Women scheduled for elective CD during spinal anesthesia were randomized to receive a perioperative oral course of either gabapentin (600 mg preoperatively followed by 200 mg every 8 h for 2 days) or placebo. Postoperative pain was measured at 24 and 48 h, at rest and on movement, on a visual analogue scale (VAS, 0 to 100 mm). The primary outcome was pain on movement at 24 h. Neonatal outcomes, opiate consumption, VAS satisfaction (0 to 100 mm), adverse effects, and persistent pain were also assessed.

Results:
Baseline characteristics were similar between groups. There was a statistically significant but small reduction in VAS pain score (mean [95% CI]) on “movement” (40 mm [36 to 45] vs. 47 mm [42 to 51]; difference, −7 mm [−13 to 0]; P = 0.047) at 24 h in the gabapentin (n = 100) compared with control group (n = 97). There was more sedation in the gabapentin group at 24 h (55 vs. 39%, P = 0.026) but greater patient VAS satisfaction (87 vs. 77 mm, P = 0.003).

Conclusions:
A perioperative course of gabapentin produces a clinically insignificant improvement in analgesia after CD and is associated with a higher incidence of sedation.
Competition and supply chain integration: a taxonomy perspective
Authors: Cao Zhi , Huo Baofeng , Li Yuan , Zhao Xiande 
Published: June 2015

Purpose– The purpose of this paper is to investigate the influence of competition on supply chain integration (SCI).Design/methodology/approach– Survey data from 617 manufacturers in China were used in this study. Taxonomy with cluster analysis was used to investigate the patterns of competition, and analysis of variance (ANOVA) was used to investigate the influence of these competition patterns on SCI.Findings– Seven competition patterns composed of local competition, international competition, and operational challenges were identified from the survey data. The ANOVA results showed that companies with different patterns achieved significantly different levels of SCI, indicating that higher levels of local competition, international competition, and operational challenges drove higher levels of SCI.Post hocanalyses revealed that international competition had stronger effects than local competition on SCI.Research limitations/implications– The data were collected from a single country, which may limit the generalization of the findings. The data were cross-sectional and thus lacked causal explanatory power.Practical implications– The findings provide suggestions for managers to use different configurations of SCI to adapt to different patterns of competition.Originality/value– This study makes three main contributions to the literature. First, it extends the research on the relationship between competition and cooperation to the supply chain management area. Second, it extends the concept of competition by incorporating not only competitive intensity, but also competitive scope and competitive capability. Third, the use of a configuration approach rather than a dimensional approach to investigate the effects of competition on SCI solves many methodological problems.
