Authors: Van Hung Nguyen , Toan Nguyen Cong , Ba Duc Nguyen , Vuong Dinh Quoc 
Published: September 2015

Abstract
Thermodynamic properties of semiconductor
compounds have been studied based on Debye-Waller factors
(DWFs) described by the mean square displacement
(MSD) which has close relation with the mean square relative
displacement (MSRD). Their analytical expressions
have been derived based on the statistical moment method
(SMM) and the empirical many-body Stillinger-Weber potentials.
Numerical results for the MSDs of GaAs, GaP, InP,
InSb, which have zinc-blende structure, are found to be
in reasonable agreement with experiment and other theories.
This paper shows that an elements value for MSD is
dependent on the binary semiconductor compound within
which it resides.
Sports utility semiotics: A semantic differential study of symbolic potential in automobile design
Authors: Wilson Andrew , Haładewicz-Grzelak Małgorzata 
Published: September 2015

AbstractThe article aims to illuminate the issue of symbolic potential in postmodern society through a semiotic study of car design. In Baudrillard’s terminology, we explore the experience and sociological and psychological materiality of objects that, being above objects’ perceptible materiality, constantly modify the integrity of technological systems (Baudrillard 2005 [1968]: 6). The target concepts are analyzed through Baudrillard’s lens of symbolic capital and his technological system of objects, coupled with the method of semantic differential (SD; e.g., Osgood 1979, 1981) against the insights of Tartu semiotics. Such a complex framework helps to establish affective attitudes of the subjects towards scales selected for their perceptual saliency. The analysis is based on the responses of students in a Polish university who were administered an instrument comprising 14 concepts and 37 scales. The results of statistical analysis yield a semantic space with two factors: potency and activity/dynamism, which we shall call social prestige. At this stage of the analysis we could not determine the evaluation factor. The scales that loaded significantly showed that there is indeed an increment of perceptual saliency in both extracted factors in the case of target stimuli (pickups and SUVs).

Published: September 2015

Abstract
The auxiliary equation method presents wide applicability to handling nonlinear wave equations. In this article, we establish new exact travelling wave solutions of the nonlinear Zoomeron equation, coupled Higgs equation, and equal width wave equation. The travelling wave solutions are expressed by the hyperbolic functions, trigonometric functions, and rational functions. It is shown that the proposed method provides a powerful mathematical tool for solving nonlinear wave equations in mathematical physics and engineering. Throughout the article, all calculations are made with the aid of the Maple packet program.
Fano Antiresonance and Kondo Resonance for Electronic Transport Through a Laterally Coupled Carbon-Nanotube Quantum-Dot System
Authors: Huo Dong-Ming 
Published: September 2015

Abstract
We present nonequilibrium Green function calculations for electronic transport through a laterally coupled carbon-nanotube quantum-dot system. In this system, a one-dimensional double carbon nanotube quantum dot attached to polarised electrodes forms a main channel for electronic tunnelling. Each carbon nanotube quantum dot in the main channel couples to a dangling carbon nanotube quantum dot. Then, the conductance spectrum is calculated. The insulating band and resonance peak in this spectrum, due to Fano antiresonance and Kondo resonance, are discussed. The intradot electron’s Coulomb interaction effect on the insulating band is also investigated. By controlling the coupling coefficient between the quantum dots, we can realise mutual transformation between Kondo resonance and Fano antiresonance at the Fermi level. The spin-orbit coupling and magnetic field’s influence on the Kondo resonance peak are discussed in detail. Finally, spin magnetic moment and orbital magnetic moment of electrons in the quantum dot by applying parallel magnetic field are also predicted.
Sonochemical synthesis of 5-substituted 1H-tetrazoles catalyzed by ZrP2O7 nanoparticles and regioselective conversion into new 2,5-disubstituted tetrazoles
Authors: Safaei-Ghomi Javad , Paymard-Samani Soleiman , Zahedi Safura , Shahbazi-Alavi Hossein 
Published: September 2015

Abstract
The ultrasound-assisted preparation of 2-(1H-tetrazol-5-yl) acrylonitrile derivatives via a one-pot multi-component method is described successfully using ZrP2O7 nanoparticles as a catalyst. Readily available tetrazoles can be transformed into the corresponding 1,5- and 2,5-disubstituted tetrazoles. 2,4′-Dibromoacetophenone gave the corresponding 2,5-disubstituted derivative as the only isomer. Synthesis of tetrazole derivatives with excellent yields in short times, a wide range of products under ultrasound irradiation, environmental benignity and a simple work-up procedure are some of the important features of this protocol.
Regulation of Notch Signaling by an Evolutionary Conserved DEAD Box RNA Helicase, Maheshvara in Drosophila melanogaster

Published: September 2015

Abstract
Notch signaling is an evolutionary conserved process that influences cell fate determination, cell proliferation, and cell death in a context-dependent manner. Notch signaling is fine-tuned at multiple levels and misregulation of Notch has been implicated in a variety of human diseases. We have characterized maheshvara (mahe), a novel gene in Drosophila melanogaster that encodes a putative DEAD box protein that is highly conserved across taxa and belongs to the largest group of RNA helicase. A dynamic pattern of mahe expression along with the maternal accumulation of its transcripts is seen during early stages of embryogenesis. In addition, a strong expression is also seen in the developing nervous system. Ectopic expression of mahe in a wide range of tissues during development results in a variety of defects, many of which resemble a typical Notch loss-of-function phenotype. We illustrate that ectopic expression of mahe in the wing imaginal discs leads to loss of Notch targets, Cut and Wingless. Interestingly, Notch protein levels are also lowered, whereas no obvious change is seen in the levels of Notch transcripts. In addition, mahe overexpression can significantly rescue ectopic Notch-mediated proliferation of eye tissue. Further, we illustrate that mahe genetically interacts with Notch and its cytoplasmic regulator deltex in trans-heterozygous combination. Coexpression of Deltex and Mahe at the dorso-ventral boundary results in a wing-nicking phenotype and a more pronounced loss of Notch target Cut. Taken together we report identification of a novel evolutionary conserved RNA helicase mahe, which plays a vital role in regulation of Notch signaling.
Plasma volume after heat acclimation: Variations due to season, fitness and methods of measurement
Authors: Loeppky JA 
Published: September 2015

Purpose
The reported magnitude of plasma volume increase (Δ%PV) following heat acclimation (HA) varies widely. Variations may result from differences in measurement techniques, season and subjects’ fitness. This report compares direct and indirect measurements of Δ%PV after 10 days of HA from studies in winter (WIN, n = 8) and summer (SUM, n = 10) in men, age 21–43 yr, at two fitness levels (VO2max: 35 and 51 ml/min/kg). Direct measurements were made before and after HA (cycling at 30% of VO2max at 50 °C, for 100 min/day) by carbon monoxide (CO) rebreathing and compared with indirect estimates from changes in hematocrit, hemoglobin and plasma protein concentration.

Results
Overall, Δ%PV by CO was small (2.9%) and greater in SUM than WIN (5.0 vs. 0.3%). Red cell, blood and plasma volumes/kg lean body mass increased in SUM and decreased in WIN, the difference being significant, and Δ%PV by CO was similar for high and low VO2max.

Conclusion
Overall, indirect estimates of Δ%PV by hemoglobin and hematocrit were similar to CO, but tended to differentiate by fitness and not season. The difference in THb increase in SUM and decrease in WIN was significant. This probably accounts for the differences from the seasonal and fitness results by the direct CO method.
Wellbore-Trajectory Control by Use of Minimum Well-Profile-Energy Criterion for Drilling Automation
Authors: Liu Zhengchun , Samuel Robello 
Published: September 2015

Summary
When the actual well path deviates from the planned path, it is imperative for a drilling system to take corrective actions. A new trajectory-control model has been developed on the basis of a minimum well-profile-energy criterion to achieve smooth well paths. In this model, the S-shaped returning path from a deviated position to the planned wellbore trajectory is divided into two sections, each of which has its length, inclination-change rate, and azimuth-change rate. Different trajectory-calculation algorithms are used to solve the deviation-correction parameters of the two sections. Results obtained from the simple balanced tangential method, the industry-standard minimum-curvature method, and the more-accurate natural-curve method are consistent with one another. The model was tested by use of wellbore-trajectory simulations of different 2D and 3D well paths. The simulation results show that the new trajectory-control model, in comparison with proportional-integral-derivative (PID) -control and fuzzy-control methods, yields much-smoother wellbore trajectories. Consequently, the new model is promising for the reduction of torque, drag, and friction of the drillstring.
Unlike PID- and fuzzy-control methods, which usually require subjective entry of several controller parameters, the new trajectory-control model provides deterministic solutions on the basis of an objective minimum-energy criterion, which represents a significant advantage for the limited computation power of downhole tools. In addition, the settings of constant inclination- and azimuth-change rates in each correction section also provide benefits, such as requiring less-frequent steering, resulting in reduced electric-power consumption and reduced abrasion failure of downhole tools.
Audit Firms' Client Acceptance Decisions: Does Partner-Level Industry Expertise Matter?
Authors: Hsieh Yu-Ting , Lin Chan-Jane 
Published: September 2015

SUMMARY
This study examines whether auditor industry expertise affects firms' client acceptance decisions. Analyzing listed firms in Taiwan, where audit partners' signatures are disclosed on the audit report, we find that partner-level industry specialists, rather than firm-level industry specialists, are less likely to accept clients with higher audit risk. We also provide weak evidence that partner-level industry specialists are less likely to accept clients with higher financial risk. This is consistent with the notion that partner-level industry specialists have an incentive to protect their reputation when making client acceptance decisions. In 2002, following the spirit of the Sarbanes-Oxley Act (SOX), the Securities and Futures Commission in Taiwan adopted a series of new rules to improve audit quality. We examine the effect of SOX on client acceptance decisions and the results indicate that partner-level industry specialists manage risk by accepting clients with less audit risk since litigation risk increased after SOX.

Published: September 2015

ABSTRACTObjective: To determine if 2-DeNT Oral Topical Powder is an effective treatment for traumatic oral ulcers.Materials and Methods: Of the 46 patients who were randomly allocated, 20 patients from the experimental group and 17 from the placebo control group completed the study. The patients, operators, and evaluators were all blinded. Patients applied the powder twice a day and completed a diary twice a day for 10 days. The diary was used to monitor the size of the lesions and pain levels (using a 10-cm visual analog scale).Results: By day 5, the ulcers in the experimental group had reduced in size by approximately 70%; and ulcers in the control group had reduced in size by 56%. The experimental-group ulcers were significantly (P &lt; .05) smaller than the control-group ulcers from day 5 through day 9. Ulcers in the experimental group were completely resolved by day 8, whereas control-group ulcers were still present on day 10. Patients experienced a significant amount of stimulated pain until the night of day 2 in the experimental group and until the night of day 5 in the control group, but group differences in pain were not statistically significant.Conclusions: The 2DeNT Oral Topical powder was more effective than the placebo powder at accelerating the healing of oral traumatic ulcers.
Estimating the location of the center of resistance of canines
Authors: Jiang Feifei , Kula Katherine , Chen Jie 
Published: September 2015

ABSTRACT

Objective:
To develop a method to quickly estimate the location of center of resistance (CR) in mesial-distal (MD) and buccal-lingual (BL) directions from the tooth's image.

Materials and Methods:
The maxillary cone-beam computed tomography (CBCT) scans of 18 patients were used. Finite element (FE) models of the canines and their surrounding tissues were built based on their CBCT scans to calculate the locations of CR. Root length, centroid of the contact surface (CCS), and centroid of projection of the contact surface (CPCS) were also obtained from the images. The CCS and CPCS locations were projected on the tooth's long axis, which were represented as percentages of the root length measured from the root's apex.

Results:
Using the FE results as the standards, the errors of using CCS or CPCS to estimate CR were calculated. The average location of CR calculated using the FE method was 60.2% measured from the root’s apex in the MD direction and 58.4% in the BL direction. The location of the CCS was 60.9%. The difference in CR was 0.7% in the MD direction and 2.5% in the BL direction. The location of CPCS was 60.2% in the MD direction and 59.1% in the BL direction, which resulted in a 0.1% and 0.8% difference with the reference CR, respectively. The average difference of CR in the MD and BL directions was small but statistically significant (P &lt; .05).

Conclusion:
The locations of the CR of a human canine in the MD and BL directions can be estimated by finding the CPCSs in those directions.
Role of Type 1 Diabetes–Associated SNPs on Autoantibody Positivity in the Type 1 Diabetes Genetics Consortium: Overview
Authors: Rich Stephen S. , Concannon Patrick 
Published: September 2015

OBJECTIVE
Type 1 diabetes (T1D) arises from the autoimmune destruction of the β-cells of the pancreas, resulting in dependence on exogenously administered insulin for survival. Key biomarkers of the autoimmune process in T1D are the occurrence of autoantibodies directed against β-cells and other antigens. The Type 1 Diabetes Genetics Consortium (T1DGC) assembled collections to 1) discover genes that modify the risk of T1D, 2) conduct phenotyping related to risk, and 3) make available biologic and genetic resources for research. The goal of the T1DGC Autoantibody Workshop was to use T1DGC phenotypic, genotypic, and autoantibody data on affected sibling pair (ASP) families to discover genes accounting for variation in presence of autoantibodies.

RESEARCH DESIGN AND METHODS
The T1DGC provided the working groups with autoantibody and genetic data on 9,976 subjects from 2,321 ASP families. Data were distributed to numerous working groups for analyses of specific autoantibody subsets and targets.

RESULTS
Seven groups analyzed the joint autoantibody and genetic data within the ASP families. Six reports are provided in this collection, ranging from candidate gene analyses of selected autoantibodies to evaluation of regions of genetic variants associated with autoimmunity on the collection of autoantibodies.

CONCLUSIONS
Although selected variants in the available genes remain important genetic predictors for prevalence of T1D, other genes and nongenetic factors are expected to contribute to the initiation of islet autoimmunity, the first step in the pathogenesis of T1D.

Published: September 2015

Abstract

Merremia quinquefolia, is an important medicinal plant of the family Convolvulaceae known for its vasoconstrictor, uterotonic, neurohormonic, sympathicolytic and sedative effects. In the present investigation effect of cytokinins 6-benzylaminopurine (BAP), kinetin (Kn) and thidiazuron (TDZ), at concentrations 1.0, 2.0, 3.0, 4.0 and 5.0 mg·dm−3 on in vitro shoot multiplication from nodal explants of M. quinquefolia was evaluated. Bud breaking and emergence of shoots started within 10-15 days of inoculation in all media containing cytokinin. Murashige and Skoog (MS) medium supplemented with 4.0 mg·dm−3 BAP resulted in maximum number of shoots from single node within 45 days. In vitro raised shoots were successfully rooted on ½ mineral salts of MS medium with 3% sucrose supplemented with 2.0 mg·dm−3 indole-3-butyric acid (IBA). This is the first report on in vitro propagation of Merremia quinquefolia. This study can be useful for development of micropropagation protocols for related taxa.

Authors: Krzymińska Agnieszka , Ulczycka-Walorska Maria 
Published: September 2015

Abstract
Experiments were conducted on the response of Plectranthus forsteri ‘Nico’ to NaCl. Plants were grown in pots of 1.5 dm3 and 0.15 dm3 water solution of NaCl at concentrations 0, 5, 10, 15, 20 g dm−3 in 2011 and 0, 10, 20, 30, 40 g dm−3 in 2012 were applied one time in the beginning of experiment. Sodium chloride applied at 10-40 g NaCl·dm−3 water, reduced plant growth and values of SPAD readings. It may be stated that Plectranthus forsteri ‘Nico’ plants are tolerant to medium concentrations of sodium chloride (5-20 g NaCl·dm−3 water) and therefore can be planted in flowerbeds in urbanized areas.

Published: September 2015

Abstract
The purpose of the presented study was to determine the best mineral composition of media and plant growth regulators in the micropropagation of the ‘Gisela 5’ (Prunus cerasus × P. canescens) dwarf sweet cherry rootstock. Nodal explants from young healthy shoots were excised and cultured on Murashige and Skoog medium without growth regulators. In vitro raised shoot tips were transferred to three culture media including Murashige and Skoog (MS), Driver and Kuniyuki (DKW) and Lloyd and McCown (WPM) containing benzyl adenine (BA) (0.5, 1 or 2 mg·l−1) in combination with kinetin (Kin) at 0 or 0.5 mg·l−1. WPM and DKW media were proving to be the most effective, resulting in a higher percentage of shoot multiplication and shoot number as compared to MS. BA in concentration 2 mg·l−1 resulted in the highest number of microshoots per explant (3.1). For rooting, 0, 0.5, 1 or 2 mg·l−1 indole-3-butyric acid (IBA) on MS, DKW and WPM media were tested. WPM medium containing 2 mg·l−1 IBA was most effective for rooting (93.7%) in comparison to MS (53.1%) and DKW (14.0%). Rooted plantlets were successfully hardened and established in pots.

The study indicated ‘Chrobry’ as the cultivar of the most favorable quality features. It was characterized by high antioxidant activity, high content of dry mass, soluble sugars and betalain pigments. Among cultivars of cylindrical shaped roots, content of soluble sugars and antiradical activity was the highest in ‘Regulski Cylinder’ roots.
Ecology and phylogeny of birds foraging at outdoor restaurants in Sweden
Authors: Haemig Paul , Sjöstedt de Luna Sara , Blank Henrick , Lundqvist Henrik 
Published: September 2015

Birds frequently visit the outdoor serving areas of restaurants to feed on scraps of food and leftovers. Although this feeding association between humans and birds is widespread and could have significant effects, both positive and negative, for all taxa involved, the authors know of no published studies that have investigated restaurant bird communities. To lay the foundation for future research, the authors conducted a basic study of birds at 80 outdoor restaurants in Sweden, identifying which species and taxonomic clades of birds visited the restaurants and comparing restaurant birds in urban and rural environments.
Thirteen species of birds visited the outdoor restaurants. Eight of these species were predominant, i.e. accounting for 51% or more of bird presence (sum of minutes of all individual birds) at one or more restaurants. Every restaurant studied had a predominant species, but species often differed from each other in frequency of predominance in different landscapes. No endangered species were seen visiting restaurants. However, three farmland bird species (House Sparrow Passer domesticus, White Wagtail Motacilla alba, Eurasian Tree Sparrow Passer montanus), whose numbers are reported to be declining in the countryside, were predominant at the majority of restaurants in rural areas, suggesting that rural restaurants might be able to contribute to the conservation of these species. The thirteen species of restaurant-visiting birds belonged to five monophyletic clades. Ninety percent of all restaurants had, as their predominant species, birds from either Clade A (Passeridae, Motacillidae, Fringillidae) or Clade C (Corvidae). Statistical testing revealed that Clade A and Clade C were distributed differently in environments along the urban-rural gradient. At all spatial scales measured, birds of Clade C were predominant at the majority of restaurants in urban areas, while birds of Clade A were the predominant clade at the majority of restaurants in rural areas. The authors use this evidence, and observations of birds foraging in association with other primates, to hypothesize that the outdoor serving areas of modern restaurants may be helping to preserve and nurture ancient human-bird symbioses that have been part of human ecology since antiquity.
