Authors: Deeley Robin J. , Putnam Ian F. , Strung Karen R. 
Published: February 2016

Abstract
The principal aim of the present paper is to give a dynamical presentation of the Jiang–Su algebra. Originally constructed as an inductive limit of prime dimension drop algebras, the Jiang–Su algebra has gone from being a poorly understood oddity to having a prominent positive role in George Elliott’s classification programme for separable, nuclear

-algebras. Here, we exhibit an étale equivalence relation whose groupoid

-algebra is isomorphic to the Jiang–Su algebra. The main ingredient is the construction of minimal homeomorphisms on infinite, compact metric spaces, each having the same cohomology as a point. This construction is also of interest in dynamical systems. Any self-map of an infinite, compact space with the same cohomology as a point has Lefschetz number one. Thus, if such a space were also to satisfy some regularity hypothesis (which our examples do not), then the Lefschetz–Hopf Theorem would imply that it does not admit a minimal homeomorphism.

Published: February 2016

Abstract
As an important protein, UL31 has been demonstrated to play multiple roles in herpes simplex virus 1 (HSV-1) replication. Previous studies showed that UL31 predominantly locates in the nucleus in chemical fixed cells and live cells, however, the determining mechanisms for its nuclear translocation is not clear. In the present study, by utilizing live cells fluorescent microscopy and co-immunoprecipitation assays, the nuclear import of UL31 was characterized to be dependent on Ran-, importin α1- and transportin-1-mediated pathway. Therefore, these results will promote the understanding of UL31-mediated biological functions in HSV-1 infection cycle.

Published: February 2016

Abstract
Cardiac glycosides (CGs) or cardiotonic steroids, which constitute a group of naturally occurring compounds with a steroid-like structure, can act on Na+/K+-ATPase as a receptor and activate intracellular signaling messengers leading to a variety of cellular responses. Epidemiological studies have revealed that CGs, used for the treatment of cardiac disorders, may also be beneficial as anti-cancer agents. CGs, acting in combination with other chemotherapeutic agents, may significantly alter their efficiency in relation to cancer cell elimination, causing both sensitization and an increase in cancer cell death, and in some cases resistance to chemotherapy. Here we show the ability of CGs to modulate apoptotic response to conventionally used anti-cancer drugs. In combination with etoposide, CGs digoxin may enhance cytotoxic potential, thereby allowing the chemotherapeutic dose to be decreased and minimizing toxicity and adverse reactions. Mechanisms behind this event are discussed.

Published: February 2016

Abstract
Unsaturated fatty acids can be converted into mono and dicarboxylic acids, which are applicably valuable materials, through oxidative cleavage reaction in the presence of a highly efficient catalyst/oxidant system. In this work, two types of advanced heterogeneous catalysts have been developed; (i) high surface area mesoporous tungsten oxide/γ-alumina mixed metal oxide, and (ii) surfactant-capped tungsten oxide nanoparticles. Various technique including N2 adsorption/desorption isotherms, XRD, SEM, EDS, TGA and catalytic test were used to monitor the physicochemical and catalytic properties of these materials. The characterization results revealed that type (i) materials exhibit high surface area and narrow particle size distribution, and the used surfactant could quantitatively enough cap the surface of type (ii) materials. The catalytic activities of these materials in the oxidative cleavage of oleic acid with H2O2 as oxidant were investigated. GC-MS was used to determine the produced amounts of desired products, azelaic and pelargonic acids. The catalytic test results showed more than 90 % conversion for type (ii) catalyst in 5 h reaction at 120 °C with acceptable production yields for azelaic and pelargonic acids. The significantly higher activity of this catalyst compared to type (i) arises from the interesting surface properties of tungsten oxides nanoparticles, which make them able to exploit the good features of homogeneous and heterogeneous catalysts.

Published: February 2016

Abstract: This study aimed to translate the Vineland Adaptive Behavior Scale (VABS) II Survey Form into Hindi and then adapt and use it in evaluating 3–9 year-old Indian children.The VABS II was translated to Hindi and its reliability and validity were checked. Then, it was used in a sample of 3–9 year-old children. Adaptive behavior composite (ABC) Scores, domain standard scores (DSS) and maladaptive-v scores (MBI) were compared.: Out of 433 items, 44 (10.16%) needed adaptation but no satisfactory adaptation could be made for 16 (3.6%). The adapted instrument was proven reliable and valid. Significant differences were found in all domains (except MBI) with higher scores for urban vs. rural children, school-goer vs. non-school-goer, working vs. housewife mothers and higher socioeconomic status (SES), but not between children of joint and nuclear families. Motor development significantly correlated with weight-for-age percentage, which in turn, correlated to the variables studied.The VABS was satisfactorily translated and adapted for Indian children. In addition, it was found that socioeconomic status significantly affected the social development.
Korean early childhood educators’ self-reported versus observed strategies for addressing challenging behaviors: an exploratory study
Authors: Kim Yeon ha , Stormont Melissa 
Published: February 2016

AbstractThe present study is an extension of past research profiling 34 Korean early childhood educators’ observed behavior support strategies in natural settings. Data regarding their self-reported strategy profiles were additionally collected and compared to their observed strategy profiles. Discrepancies were found between teachers’ reported and observed strategies. Teachers reported that they implemented precorrection and behavioral-specific praise more often than redirection or reprimand/punishment. However, they were observed implementing redirection more often than precorrection and behavioral-specific praise was least frequently implemented. Furthermore, no correlations were found between teachers’ observed and reported strategies. Implications of these findings are discussed.
Migration and Regional Wage Disparities in Germany
Authors: Fendel Tanja 
Published: February 2016

AbstractThis study provides an analysis of the effect of migration and commuting on regional wage disparities in Germany. Using the INKAR dataset and the GSOEP from the years 1998 to 2009, dynamic GMM panel estimations are applied to consider dynamics as well as the simultaneity between migration and regional labor market circumstances. To begin with, the influence of migration on relative wage levels is analyzed. The results show a small positive wage effect due to the overall regional migration balance. However, only domestic migration is relevant for analyzing the influence of migration on regional wage disparities. The wage effect due to domestic migration turns out to be smaller and negative. Regions seem to benefit primary from a combination of internal and foreign migration, however effects are small. Assuming that individuals usually move to high-wage regions, the negative wage effect of German migration would trigger an adjustment mechanism of wage disparities. Therefore, a second dynamic GMM panel estimation tests whether an influence of the regional wage levels on migration exists. Results show no statistically significant effects. An adjustment of existing wage disparities due to migration is not likely to occur in Germany in the next few years.
Life Satisfaction in Germany After Reunification: Additional Insights on the Pattern of Convergence
Authors: Petrunyk Inna , Pfeifer Christian 
Published: February 2016

Abstract
The authors update previous findings on the total East-West gap in overall life satisfaction and its trend by using data from the German Socio-Economic Panel (SOEP) for the years 1992 to 2013. Additionally, the East-West gap and its trend are separately analyzed for men and women as well as for four birth cohorts. The results indicate that reported life satisfaction is on average significantly lower in East than in West German federal states and that part of the raw East-West gap is due to differences in household income and unemployment status. The conditional East-West gap decreased in the first years after the German reunification and remained quite stable and sizeable since the mid-nineties. The results further indicate that gender differences are small. But the East-West gap is significantly smaller and shows a trend towards convergence for younger birth cohorts.
Local Quasi-equilibrium Description of Multiscale Systems
Authors: Santamaría-Holek Iván , Pérez-Madrid Augustin , Miguel Rubí J. 
Published: February 2016

Abstract
Systems whose dynamics result from the existence of a wide variety of time and length scales frequently exhibit slow relaxation behavior, manifested through the aging compartment of the correlations and the nonexponential decay of the response function. Experiments performed in systems such as amorphous polymers and supercooled liquids and glasses seem to indicate that these systems undergo, in general, non-Markovian and nonstationary dynamics. Hence, in this contribution, we present a dynamical description of slow relaxation systems based on a generalization of Onsager’s theory to nonequilibrium aging states. By assuming the existence of a local quasi-equilibrium state characterized by a nonstationary probability distribution the entropy of the system is expressed in terms of the conditional probability density by means of the Gibbs entropy postulate. Thus, by taking into account probability conservation and the rules of nonequilibrium thermodynamics, the generalized Fokker–Planck equation is derived.

AbstractTo evaluate intraoperative and early postoperative outcomes of a novel placenta delivery technique; extra-abdominal removal vs. intra-abdominal removal of the placenta during cesarean section (CS).A total of 210 women delivering by CS at term in a tertiary university hospital between March 2014 and January 2015 were randomized to extra-abdominal removal vs. intra-abdominal removal of the placenta. The women were randomly allocated to the extra- (group 1) or intra-abdominal removal group (group 2) according to random sampling method, where women with even and odd numbers were allocated to intra- and extra-abdominal groups, respectively. The amount of intra-abdominal hemorrhagic fluid accumulation, the duration of operation and estimated blood loss during operation were the primary outcomes. The secondary outcomes included the mean difference between pre- and post-operative hemoglobin and hematocrit levels, the mean postoperative pain score, any additional need of analgesia, postoperative bowel function, postoperative endometritis and wound infections.The amount of aspirated hemorrhagic fluid was significantly higher in the intra-abdominal group compared to the extra-abdominal group (34.6±22.2 mL vs. 9.4±4.8 mL, P<0.001). Mean duration of the operation, intraoperative blood loss, postoperative requirement of additional analgesia, postoperative pain scores, postoperative endometritis or wound infection, and length of hospital stay were not significantly different between the intra- and extra-abdominal placental removal groups.By extra-abdominal removal of the placenta, the accumulation of bloody fluid in the abdominal cavity is significantly less compared to the intra-abdominal removal method, which, in turn, provides avoidance of excessive mounted-gauze use, intra-abdominal manipulations, or iatrogenic trauma.

Green Chemistry in action: towards sustainable production of Gold nanoparticles
Authors: Mnisi Robert L. , Ndibewu Peter P. , Mokgalaka Ntebogeng S. 
Published: February 2016

Abstract
This study reports the synthesis of gold nanoparticles from a gold precursor salt (HAuCl4·3H2O) using Moringa oleifera bark broth, a cheap renewable material, without adding external surfactant, capping agent or template. Biomolecules responsible for reducing Au3+ to Au0 and stabilization of the resulting nanoparticles were extracted from the bark, and the synthesis was monitored for precursor concentration, percentage broth, pH of reaction media and reaction time. The biosynthesized nanoparticles were characterized using spectroscopic (FTIR and UV-Vis) techniques, advanced microscopic imaging (HRTEM, SEM/EDS), and Zeta potential measurements. Distinct color change from yellow to wine red was observed, indicative of the formation of gold particles at nanoscale. The SPR band was found at around 550 nm, in agreement with conventional synthetic protocols. The particles were stable with a net negative surface charge (–20 mV), a contribution associated with the protein nature of the broth. Addition of Pb2+ to the polydisperse nanoparticle suspension resulted in a color shift, to a faint blue color, coupled with a corresponding SPR shift to higher wavelengths, depending on the concentration of Pb2+ added. This color change is attributed to the aggregation of the colloidal particles due to complexation effects of the metal ions with the biomolecules on the surface of the nanoparticles.
Shedding light on the hydrophobicity puzzle
Authors: Graziano Giuseppe 
Published: February 2016

Abstract
A general theory of hydrophobic hydration and pairwise hydrophobic interaction has been developed in the last years. The main ingredient is the recognition that: (a) cavity creation (necessary to insert a solute molecule into water) causes a solvent-excluded volume effect that leads to a loss in the translational entropy of water molecules; (b) the merging of two cavities (necessary to form the contact minimum configuration of two nonpolar molecules) causes a decrease in the solvent-excluded volume effect and so an increase in the translational entropy of water molecules. The performance of the theoretical approach is tested by reproducing both the hydration thermodynamics of xenon and the thermodynamics associated with the formation of the contact minimum configuration of two xenon atoms, over a large temperature range.

Provisioning, Bank Behavior and Financial Crisis: Evidence from GCC Banks
Authors: Ghosh Saibal 
Published: February 2016

AbstractThe debate on bank capital regulation has in recent years devoted specific attention to the role that bank loan loss provisions play as a part of the overall minimum capital regulatory framework. Using data for 1996–2011, we find evidence in favor of both capital management and signaling behavior by GCC banks. Islamic banks appear to engage less in such behavior as compared to their non-Islamic counterparts.
Dating US business cycles with macro factors
Authors: Fossati Sebastian 
Published: February 2016

AbstractLatent factors estimated from panels of macroeconomic indicators are used to generate recession probabilities for the US economy. The focus is on current (rather than future) business conditions. Two macro factors are considered: (1) a dynamic factor estimated by maximum likelihood from a set of 4 monthly series; (2) the first of eight static factors estimated by principal components using a panel of 102 monthly series. Recession probabilities generated using standard probit, autoregressive probit, and Markov-switching models exhibit very different properties. Overall, a simple Markov-switching model based on the big data macro factor generates the sequence of out-of-sample class predictions that better approximates NBER recession months. Nevertheless, it is shown that the selection of the best performing model depends on the forecaster’s relative tolerance for false positives and false negatives.
On the estimation of short memory components in long memory time series models
Authors: Baillie Richard T. , Kapetanios George 
Published: February 2016

AbstractA substantial amount of recent time series research has emphasized semi-parameteric estimators of a long memory parameter and we provide a selective review of the literature on this issue. We consider such estimators applied to the issue of estimating the parameters relating to a short memory process which is embedded within the long memory process. We consider the fractional differencing filter and the subsequent properties of a two step estimator of the short memory parameters. We conclude that while the semi-parametric estimators can have excellent properties in terms of estimating the long memory parameter, they do not have good properties when applied to the two step estimator of short memory
Application of a Differential Transform Method to the Transient Natural Convection Problem in a Vertical Tube with Variable Fluid Properties
Authors: Chiba Ryoichi 
Published: February 2016

AbstractThe transient natural convection of a viscous fluid in a heated vertical tube is studied using the two-dimensional differential transform method (DTM). A time-dependent Dirichlet boundary condition is imposed for tube wall temperature. The partial differential equations for the velocity and temperature fields within the tube are solved by the DTM while considering temperature-dependent viscosity and thermal conductivity of the fluid. As a result, tractable solutions in double-series form are derived for the temperature and flow velocity. The transformed functions included in the solutions are obtained through a simple recursive procedure. Numerical results illustrate the effects of temperature-dependent properties on transient temperature and flow behaviour, including the Nusselt number and volumetric flow rate. The DTM gives accurate series solutions without any special functions for nonlinear transient heat transfer problems which are advantageous in finding the derivative or integral.
The VES Hypothesis and Protein Conformational Changes
Authors: Cruzeiro Leonor 
Published: February 2016

Abstract
This work started as a (biased) review of the state of the art of the Davydov/Scott model
for energy transfer in proteins via the propagation of amide I excitations and of how this
initial quantum stage may lead to protein conformational changes. It is not a traditional
review because certain results reported in the literature have been complemented by extra
simulations which revealed, for instance, a new class of possible states for the amide I
excitation, here designated as double discrete breathers. The issue of the thermal stability
of the Davydov soliton is discussed, as well as the deeper question of how to simulate the
non-equilibrium regime of a mixed quantum-classical system at finite temperature. While an
exact answer to the latter question is not yet available, a specific formalism that is able
to reproduce the correct canonical ensemble is described. Finally, the question of how
a quantum amide I excitation can generate of the specific protein conformational changes
known to be associated with function is also explored. Indeed, computer simulations indicate
that a local action can lead to reproducible conformational changes. The paper ends with
a discussion of some of the open questions that plague/stimulate this field and with
a suggestion for an experiment to test the basic assumption of the Davydov/Scott model.
Structural Insight into Self Assembly of Sophorolipids: A Molecular Dynamics Simulation Study
Authors: Pandey Prithvi Raj , Dhasaiyan Prabhu , Prasad B. L. V. , Roy Sudip 
Published: February 2016

Abstract
Sophorolipids contain hydrophilic head groups at the ends of a long hydrophobic tail. As
a result, sophorolipids can self assemble into variety of structures in water. Atomistic
self assembly simulations of sophorolipids are performed in water. Two sophorolipids, oleic
acid sophorolipid and linolenic acid sophorolipid, differing in number of double bonds in
the hydrophobic tail are considered for this study. Long time self assembly simulations are
performed considering 1:3 lipid to water ratio by weight for both oleic and linolenic acid
sophorolipids. In addition to 1:3 ratio, long time self assembly simulations are also
performed with 1:1 and 1:2 ratios for linolenic acid sophorolipids. Distinctions in
structural arrangements of sophorolipid molecules in the self assembled configuration for
all the systems are investigated. The present study aims to provide structural insight into
the different self assembled configurations of sophorolipids in water.
