On conjugation orbits of semisimple pairs in rank one
Authors: Gongopadhyay Krishnendu , Kalane Sagar B. 
Published: June 2019

AbstractWe consider the Lie groupsSU⁢(n,1){\mathrm{SU}(n,1)}andSp⁢(n,1){\mathrm{Sp}(n,1)}that act as isometries of the complex and the quaternionic hyperbolic spaces, respectively. We classify pairs of semisimple elements inSp⁢(n,1){\mathrm{Sp}(n,1)}andSU⁢(n,1){\mathrm{SU}(n,1)}up to conjugacy. This gives local parametrization of the representations ρ inHom⁢(F2,G)/G{{\mathrm{Hom}}({\mathrm{F}}_{2},G)/G}such that bothρ⁢(x){\rho(x)}andρ⁢(y){\rho(y)}are semisimple elements inG, whereF2=〈x,y〉{{\mathrm{F}}_{2}=\langle x,y\rangle},G=Sp⁢(n,1){G=\mathrm{Sp}(n,1)}orSU⁢(n,1){\mathrm{SU}(n,1)}. We use thePSp⁢(n,1){{\mathrm{PSp}}(n,1)}-configuration spaceM⁢(n,i,m-i){{\mathrm{M}}(n,i,m-i)}of orderedm-tuples of distinct points in𝐇ℍn¯{\overline{{\mathbf{H}}_{{\mathbb{H}}}^{n}}}, where the firstipoints in anm-tuple are boundary points, to classify the semisimple pairs. Further, we also classify points onM⁢(n,i,m-i){{\mathrm{M}}(n,i,m-i)}.

Authors: Roshani Sobhan , Dehghani Khatereh , Roshani Saeed 
Published: June 2019

AbstractIn this paper a new lowpass filter (LPF) with curved line resonators and fountain shaped resonators is proposed. The proposed filter has achieved wide stopband, compact size, sharp roll-off rate and low return loss. Two tapered resonators are used to produce transmission zeros and widen the stopband. Also, a fountain shaped resonator is proposed using curved transmission lines to obtain good sharpness in the filter response. The cut-off frequency of the designed LPF is 1.74 GHz and the overall size of the designed LPF is 0.135 λg × 0.132 λgwhere λgis the guided wavelength at the cut-off frequency. The results show that the overall size of the lowpass filter could be reduced using curved line resonators and curved transmission lines.
In vitro import experiments with semi-intact cells suggest a role of the Sec61 paralog Ssh1 in mitochondrial biogenesis
Authors: Laborenz Janina , Hansen Katja , Prescianotto-Baschong Cristina , Spang Anne , Herrmann Johannes M. 
Published: June 2019

Abstract
Mitochondrial biogenesis relies on the synthesis of hundreds of different precursor proteins in the cytosol and their subsequent import into the organelle. Recent studies suggest that the surface of the endoplasmic reticulum (ER) actively contributes to the targeting of some mitochondrial precursors. In the past, in vitro import experiments with isolated mitochondria proved to be extremely powerful to elucidate the individual reactions of the mitochondrial import machinery. However, this in vitro approach is not well suited to study the influence of non-mitochondrial membranes. In this study, we describe an in vitro system using semi-intact yeast cells to test a potential import relevance of the ER proteins Erg3, Lcb5 and Ssh1, all being required for efficient mitochondrial respiration. We optimized the conditions of this experimental test system and found that cells lacking Ssh1, a paralog of the Sec61 translocation pore, show a reduced import efficiency of mitochondrial precursor proteins. Our results suggest that Ssh1, directly or indirectly, increases the efficiency of the biogenesis of mitochondrial proteins. Our findings are compatible with a functional interdependence of the mitochondrial and the ER protein translocation systems.

Abstract

Background
The Dominican Republic (DR) has some of the highest rates of sexually transmitted infections (STI) and adolescent pregnancy in the Caribbean. Well-designed comprehensive sexuality education programs (CSEP) can reduce risky sexual behavior. This study sought to evaluate the Módulo Anexo Materno Infantil (MAMI) adolescent clinic’s CSEP in changing knowledge of STI and pregnancy and attitudes towards risky sexual behavior following implementation.

Methods
A mixed methods study was conducted among students aged 11–25 years from three schools between September 2017 and February 2018. Participants in MAMI CSEP completed questionnaires, before, immediately following, and 3 months following the CSEP. Questions assessed knowledge, attitude, and sexual experience, and obtained program feedback. There was one eight-participant focus group discussion (FGD) per school. Descriptive statistics summarized sample demographics and cross-sectional responses. McNemar’s test evaluated differences in the proportions of students selecting correct responses over time. Paired t-tests compared mean test scores across time.

Result
Overall response rate was 98.7% (1414/1432), with 486 pre-tests, 448 initial post-tests, and 480 3-month post-tests. Respondents identified as 53.5% (321/600) female and 46.5% (279/600) male with mean age of 14.2 years. More males (63.4%) reported sexual experience than females (35.8%) (p < 0.001). Increases in mean scores from pre-test to post-test and pre-test to 3-month post-test were statistically significant (p < 0.001). Three themes arose from the FGDs: (1) expanding sexual and reproductive health knowledge, (2) perception of curricular content, structure and delivery, and (3) student-health educator dynamic.

Conclusion
Improvement in test scores supports MAMI CSEP’s efficacy in educating students and reinforcing positive attitudes to reduce risky sexual behavior. Utilizing an interactive health educator model provided students with clear, accurate information in a safe environment with mutual trust. Selecting health educators employed by an adolescent clinic allows them to connect students to preventive and treatment services during the CSEP.
The Web as a legal language resource
Authors: Giampieri Patrizia 
Published: June 2019

Abstract
The literature has long explored the Web as corpus for language research and practice. However, little has been written on the Web as a legal language resource. This paper is aimed at exploring the Web as a tool which can provide answers to legal language queries. In this respect, it will show how Google advanced search and the WebCorp Web concordancer can shed light on legal language and bring recurrent patterns to the surface. To this aim, a few issues will be addressed touching upon the query search syntax, the choice of the best translation candidates, the extraction of frequent collocations, the noticing of high recurrences, etc. Considering the shortcomings and the advantages of Google advanced search and of the WebCorp Web concordancer, the paper findings will argue that the Web as corpus can be a reliable legal language resource as long as a selection of tools are used, and the query syntax is accurate.
Meaning construction and judicial identification: Difficulties and countermeasures of criminal regulation of illegal fundraising behavior on online P2P lending platforms
Authors: Peng Xinlin , Luo Xiaoshuang , Li Jian 
Published: June 2019

Abstract
At present, there exist several difficulties in the criminal regulation of illegal fundraising activities on China’s P2P platforms, such as discovering, identifying, tracking, and preventing. To solve these difficulties in the criminal regulations, this study applies the problem-oriented approach to evaluate the meaning constructions of illegal fundraising behavior on online P2P lending platforms in the corresponding judicial identifications, that is, judicial regulations and interpretations. After analyzing the judicial documents of 192 criminal cases in China, this study finds that it is necessary to actively draw on successful extra-territorial experience, and further establish a reasonable balance between maintaining financial security and promoting financial innovation. Specifically, the judiciary could adjust the current single loose criminal policy into one that combines leniency with rigidity, perfect the criminal law and its interpretation system of illegal fundraising behavior on P2P platforms, strengthen the connection mechanism of punishment and execution, explore the specialized case-handling mechanism, and implement a case guidance system.
The Power-Transition Crisis of the 160s–130s BCE and the Formation of the Parthian Empire
Authors: Overtoom Nikolaus Leo 
Published: June 2019

AbstractAlexander the Great’s conquests ushered in the Hellenistic era throughout the ancient Mediterranean and Middle East. In this period, the Seleucids, one of most successful of the Successor dynasties, ruled over most of the Middle East at the height of their power. Yet two rising powers in the ancient world, Rome and Parthia, played a crucial role in the decline and eventual fall of the Seleucids. In a prior article, I argued that geopolitical developments around the Eastern Mediterranean in the middle third century BCE were indirectly responsible for the emergence of the Parthian state in Iran. Disastrous military conflicts at home and abroad in the west caused a sudden decline of Seleucid power in the 240s–230s, triggering what political scientists call a power-transition crisis. This article utilizes similar approaches to historical analysis and International Relations theory to contend that, after a period of recovery, a further sudden decline of Seleucid power in the 160s–130s triggered another power-transition crisis that brought an end to Seleucid hegemony over the Middle East permanently. The crisis facilitated the rapid transformation of the Parthian state from a minor kingdom to a major empire, drastically changing the international environment of the ancient world.
Regional Market Income Inequality and its Impact on Crime in Germany: A Spatial Panel Data Approach with Local Spillovers
Authors: Süß Philipp 
Published: June 2019

AbstractEconomic theory predicts a positive effect of an increase in income inequality on the prevalence of crime, but the international empirical evidence is mixed. For Germany, research on this topic is virtually non-existent. Therefore, I used fixed effect regressions to estimate the effect of a market income inequality proxy on property damages, thefts from motor vehicles, domestic burglaries and assaults in Germany. The models without spatial lags suggest economically small to moderate own-district elasticities between 0.13 and 0.95. The models with spatial lags generally show insignificant own-district estimates, but significant spatial spillovers.

AbstractPeople who are engineering biological organisms often find it useful to communicate in diagrams, both about the structure of the nucleic acid sequences that they are engineering and about the functional relationships between sequence features and other molecular species . Some typical practices and conventions have begun to emerge for such diagrams. The Synthetic Biology Open Language Visual (SBOL Visual) has been developed as a standard for organizing and systematizing such conventions in order to produce a coherent language for expressing the structure and function of genetic designs. This document details version 2.1 of SBOL Visual, which builds on the prior SBOL Visual 2.0 standard by expanding diagram syntax to include methods for showing modular structure and mappings between elements of a system, interactions arrows that can split or join (with the glyph at the split or join indicating either superposition or a chemical process), and adding new glyphs for indicating genomic context (e.g., integration into a plasmid or genome) and for stop codons.

Conformational changes in common monosaccharides caused by per-O-sulfation
Authors: Gerbst Alexey G. , Krylov Vadim B. , Nifantiev Nikolay E. 
Published: June 2019

Abstract
Polysulfated carbohydrates play an important role in many biological processes because of their ability to bind to various protein receptors such as different growth factors, blood coagulation factors, adhesion lectins etc. Precise information about spatial organization of sulfated derivatives is of high demand for molecular modelling of such interactions as well as for understanding of the mechanism of pyranoside-into-furanoside rearrangement. In this review we summarize the changes recently revealed for the conformations of common pyranosides and furanosides upon total O-sulfation which were studied by means of NMR spectroscopy as well as molecular modelling. It was found that pentoses, being more flexible, undergo complete conformational chair inversion. Meanwhile, for hexoses the situation strongly depends on the monosaccharide configuration. Conformational changes are most pronounced in gluco-compounds though quantum chemical calculations helped to establish that no complete chair inversion occurred. In furanosides distortions of two types were observed: either the ring conformation or the conformation of the side chain changed. The presented data may be used for the analysis of chemical, physical and biological properties of sulfated carbohydrates.

Abstract
The neuroprotective role of natural polyphenols is well established but phenolics poor water solubility affects their bioavailability and bioactivity. Aiming to overcome this issue, we were encouraged to investigate the 2-deoxyglycosylation of natural or nature inspired neuroprotective molecules, using glycals as easily accessed glycosyl donors. This robust methodology allowed the generation of a set of new resveratrol and caffeic acid ester glycosides, envisioning more effective and bioavailable compounds. Resveratrol 2-deoxyglycosides were more effective at protecting the neuronal cells from peroxide-induced cytotoxicity than resveratrol itself, while the caffeic acid ester glycoside also showed extraordinary neuroprotection activity. Coefficient partition measurements demonstrated the moderate lipophilicity of resveratrol glycosides, which Log D values are typical of a central nervous system (CNS) drug and ideal for blood-brain barrier (BBB) penetration. Passive permeation assessed by the parallel artificial membrane permeability assay (PAMPA) revealed that 2,6-dideoxy-l-arabino-hexopyranosides were more effective than 2-deoxy-d-arabino-hexopyranosides. The lack of toxicity of the neuroprotective glycosides and their promising physicochemical properties revealed the usefulness of sugar coupling towards the modulation of natural product properties and bioactivity.

Abstract
In the last decade, novel approaches for post-synthesis processes of separation and high purification of gases are gaining larger acceptance in industry. The market is competing with consolidated operations such as cryogenic distillation. The key for new approaches of distillation, membranes and crystallization in challenging and harsh environments is the development of new tough, high-performance materials that are characterized by higher energy efficiency compared with conventional cryogenic distillation. This review highlights the most promising fields of research in high purification and separation of gases by considering the elevated pressure and thermal distillations, membrane cascades, purification in synthesis by use of catalytic technologies, crystallization and hydride methods based on them.
Pathological and cognitive changes in patients with type 2 diabetes mellitus and comorbid MCI and protective hypoglycemic therapies: a narrative review

Published: June 2019

AbstractType 2 diabetes mellitus (T2DM) is becoming a significant health issue worldwide. Many studies support the hypothesis that patients with T2DM have a higher-than-expected incidence of mild cognitive impairment (MCI) than individuals without diabetes. Based on the results from recent studies, MCI might be associated with the effects of T2DM on glucose metabolism and brain atrophy. As a narrative review, we will illuminate pathological and cognitive changes in patients with T2DM and comorbid MCI and protective hypoglycemic therapies. The early abnormal signs of cognition must be elucidated, and extensive investigations are needed to develop improved therapies for use in the clinic.
Net Neutrality and Investment in the US: A Review of Evidence from the 2018 Restoring Internet Freedom Order
Authors: Ford George S. 
Published: June 2019

Abstract
In 2018, the Federal Communications Commission’s Restoring Internet Freedom Order reversed its 2015 decision to apply common carrier regulation to broadband Internet access services under Title II of the Communications Act of 1934. Empirical evidence indicating negative investment effects of the regulation played a key role in this reversal, though the quantification of these investment effects were a matter of substantial controversy. This article surveys the studies cited in the recent decision and the Commission’s scrutiny of them. In all, the Commission considered eight primary works but relied on only two of them, a culling process that relied on four principles: (1) simply comparing outcomes before-and-after an event is not a valid impact analysis; (2) before-and-after comparisons are more probative if regression analysis is used to condition the outcomes by accounting for potentially relevant factors like economic growth, sales, and so forth; (3) the causal effects of a regulation are best determined with reference to a counterfactual; and (4) the application of proper methods does not excuse the use of bad data. These principles are mostly uncontroversial and are consistent with the modern practice of impact analysis.
Transference of brand personality in brand name translation: A case study on the Chinese-English translation of men’s clothing brands
Authors: Cui Ying 
Published: June 2019

AbstractBrand names are endowed with personalities that appeal to consumers, and such personalities are often adjusted in translation. This research aims to explore the transference of brand personality dimensions in the Chinese-English translation of men’s clothing brands, which embody consumers’ values and self-perceptions as well as social cultural meanings, in the hope of revealing male consumers’ psychological characteristics and providing a reference for translators. This investigation studies the brand personality frameworks for English and Chinese consumers, analyzes a corpus of 477 Chinese-English men’s clothing brands, summarizes the major personality dimensions for men’s clothing brands, and explores how they are transferred in translation. As brand personalities reflect target consumers’ psychology to a certain extent, exploring the transference of brand personality dimensions in the Chinese-English translation of men’s clothing brands can reveal the differences between Chinese and English male consumers’ values and mentality, which can serve as a reference for translators and international businesses.

(y = 0, 1, 2, 3) compounds exhibit semiconducting behaviour at normal pressure. The energy gap of CsPbCl3 can be tuned by substituting iodine atoms for chlorine atoms. The energy gap values are found to be 3.06, 2.681, 2.330, and 2.030 eV using HSE06 calculations for CsPbCl3, CsPbCl2I, CsPbClI2, and CsPbI3, respectively. Also, it is found that the energy gap values of these materials decrease with increase in pressure and that a semiconductor-to-metallic phase transition is observed at high pressure. The optical properties of these Pb-based compounds are analysed. The dynamical stability of these perovskites is analysed by their phonon dispersion curves.
Adsorption of Dye from Wastewater onto ZnO Nanoparticles-Loaded Zeolite: Kinetic, Thermodynamic and Isotherm Studies

Published: June 2019

Abstract
The adsorption process of methylene blue (MB) and its removal from aqueous solution at initial pollutant concentration range of 1–7 ppm was investigated. Zeolite-A (Z) and its ZnO-loaded species (Z/ZnO) were prepared via microwave technique from natural resource and applied for dye removal. The loading of ZnO was governed by the cation exchange property of zeolite, followed by calcination. Experimentally, Z and Z/ZnO were tested using X-ray Diffraction (XRD), Fourier-Transform Infrared (FTIR), Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and N2 adsorption-desorption. The examined parameters such as concentration of dye, contact time, ZnO dose and solution pH were traversed. Three isothermal models were analyzed. Kinetic studies indicated that, the adsorption of MB matched with pseudo-second order model. The maximum removal efficiency at pH 3, increased from 67.8% for Z to 94.8% for Z/ZnO modified with 3% ZnO loads (Z/ZnO(3%)). Parameters such as ΔH, ΔS, ΔG, S* and Ea were thermodynamically calculated. Langmiur isotherm and pseudo-second order models were the best fitting for the obtained data. The results indicated that, the adsorption of MB dye is spontaneous and endothermic, the removal efficiency is favored by increasing the temperature. ZnO-zeolite has much higher adsorption capacity for eliminating MB dye than that of the un-loaded zeolite.
