Rational homology and homotopy of high-dimensional string links
Authors: Songhafouo Tsopméné Paul Arnaud , Turchin Victor 
Published: April 2018

Abstract
Arone and the second author showed that when the dimensions are in the stable range, the rational homology and homotopy of the high-dimensional analogues of spaces of long knots can be calculated as the homology of a direct sum of finite graph-complexes that they described explicitly. They also showed that these homology and homotopy groups can be interpreted as the
higher-order Hochschild homology, also called Hochschild–Pirashvili homology.
In this paper, we generalize all these results to high-dimensional analogues of spaces of string links.
The methods of our paper are applicable in the range when the ambient dimension is at least twice the maximal dimension of a
link component plus two, which in particular guarantees that the spaces under study are connected. However, we conjecture that our homotopy graph-complex computes the rational homotopy groups of
link spaces always when the codimension is greater than two, i.e. always when the Goodwillie–Weiss calculus is applicable. Using Haefliger’s approach to calculate the groups of isotopy classes of higher-dimensional links, we confirm our conjecture at the level of

Authors: Lu Jui-Han , Hung Ming-Tsung 
Published: April 2018

Abstract
A MIMO dipole antenna with triple band operation for 4 G LTE femtocell is proposed. This designed dipole antenna with a regulated RL ≥ 10 dB can achieve 128/1007 MHz (18.3/39.2 %) for the LTE 700/2300/2500 MHz operating bands respectively. The measured maximum peak antenna gains and efficiencies approach 4.8/7.4 dBi and 92/88 % across 700/2300/2500 MHz bands, respectively, which cover the required bandwidth for 4 G LTE system, and the compliant unidirectional radiation patterns show in XZ- and XY-plane.
Design of a Compact Balanced Bandpass Filter based on CSRR-loaded Substrate Integrated Waveguide Structure
Authors: Zhang Hao , Kang Wei , Wu Wen 
Published: April 2018

Abstract
A compact balanced bandpass filter (BPF) based on complementary split ring resonator (CSRR) -loaded substrate integrated waveguide (SIW) structure is reported in this paper. Both TE102 and TE201 modes of the SIW cavity can be excited under differential-mode (DM) operation with the proper positions of the balanced feeds. Meanwhile, the CSRR etched on the top layer of the substrate can also be excited by the axial electric excitation. Then, three transmission poles and two transmission zeros (TZs) have been obtained which improve the selectivity of the DM passband. To verify the above design concept, an X-band prototype operating at 8 GHz has been fabricated and measured. A good agreement is observed between the simulations and the measurements.

AbstractDetail results of microfaunal, sedimentological and geochemical investigations are documented from a newly discovered section of the Permian–Triassic boundary (PTB) interval in the area of the town of Valjevo (northwestern Serbia). The presence of various and abundant microfossils (conodonts, foraminifers, and ostracodes) found in the Upper Permian “Bituminous limestone” Formation enabled a determination of the ChanghsingianHindeodus praeparvusconodont Zone. This paper is the first report of latest Permian strata from the region, as well as from all of Serbia, where the PTB interval sediments have been part of a complex/integrated study by means of biostratigraphy and geochemistry.
Who Fears the Big Government? A Coordinated Attemp to Downsize Federal Agencies’ Power in the United States
Authors: Romeo Graziella , Palazzo Nausica 
Published: April 2018

Abstract
While agencies have an important role in the interplay between central government and states, their functioning impacts both separation of powers and cooperative federalism. Unorthodoxy in rule-making process serves as an example for the ways agencies can further exploit their privileged position in the frame of government. A reaction to an expansion of the weight and centrality of agencies’ decisions consisted in introducing pieces of legislation substantially downsizing agencies’ rulemaking, and in reconsidering judicial deference towards agencies’ determinations. The paper central claim is that all the three branches of government are showing to some extent a willingness to crack down on agencies: the judiciary through employing preliminary injunctions and reshaping the deference doctrine, the President and the Congress through reforms reducing the space of agencies’ actions.

Published: April 2018

Abstract
In this paper, we implement the optimal homotopy asymptotic method to find the approximate solutions of the Poisson–Boltzmann equation.
We also use the results of the conjugate gradient method for comparison with those of the optimal homotopy asymptotic method.
Our study reveals that the optimal homotopy asymptotic method gives more effective results than conjugate gradient algorithms for the considered problems.
Characterization and low-cost, green synthesis of Zn2+ doped MgO nanoparticles
Authors: Mohammad Shafiee Mohammad Reza , Kargar Mahboubeh , Ghashang Majid 
Published: April 2018

Abstract
The synthesis of oxides has a significant role in their improved properties. This is why a green method is used to gain stable oxide nanoparticles. Zn2+ doped magnesium oxide (MgO) nanoparticles were synthesized through a green method, extracting Aloe vera latex media. The green method has the advantages of being a cost-effective, innocuous, eco-friendly method. Firstly, thanks to the structure of Aloe vera latex, its extract has an important role in morphology, and crystal size of MgO structure, which leads to homogenous nanoparticles dispersion. The elliptical particles with ranges from 45 nm to 65 nm were observed by scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM). Furthermore, the effect of calcination temperature was investigated, showing that increasing calcination temperature made larger particles with sharper peaks in X-ray diffraction (XRD) analysis. The strain value (ε) and crystallite size by Williamson-Hall (nm), dislocation density, and crystallinity index were evaluated. Finally, energy dispersive X-ray spectroscopy (EDS) confirmed the doping of Zn2+ in MgO nanoparticles. Fourier transform infrared (FT-IR) and HRTEM analyses were also used.

Authors: Nhivekar Girish S. , Rathod Virendra K. 
Published: April 2018

Abstract
Polyethylene glycol stearate is widely used in pharmaceuticals and cosmetic industries. The current work describes the synthesis and optimization of polyethylene glycol stearate by esterification of polyethylene glycol 600 and stearic acid using Fermase CALBex 10000, a commercial immobilized lipase B in a solvent-free system. The impact of various parameters that include temperature, reaction time, biocatalyst loading, agitation, acid to alcohol molar ratio, and amount of molecular sieves was optimized to achieve maximum conversion. The highest conversion of 86.98% was obtained in 6 h under the following optimized conditions: temperature 70°C, biocatalyst loading 0.5%, acid to alcohol molar ratio 1:4, speed of agitation 300 rpm, and molecular sieves 5% (w/w). The final condensate product was analyzed through Fourier transform infrared spectroscopy to confirm the functional group and also by 1H nuclear magnetic resonance spectroscopy. The immobilized catalyst can be reused up to four cycles, exhibiting more than 60% of its initial activity.
Evaluation of the saponin green extraction from Ziziphus spina-christi leaves using hydrothermal, microwave and Bain-Marie water bath heating methods
Authors: Mohaddes-Kamranshahi Mahdiyeh , Jafarizadeh-Malmiri Hoda , Simjoo Mohammad , Jafarizad Abbas 
Published: April 2018

AbstractSaponin as a biosurfactant was extracted from IranianZiziphus spina-christileaves using three green extraction methods namely, autoclave, microwave and Bain-Marie heating methods. In this study, three solvents namely, methanol, ethanol and water were used to extract saponin. The results revealed that water, as compared to the methanol and ethanol, is a more suitable solvent to extract saponin from theZ. spina-christileaves. The obtained results indicated that saponin extraction using autoclave provided more suitable physico-chemical properties along with a better yield. In fact, maximum foam volume (12.56 cm3), color intensity (3.24% absorbance unit [a.u.]) and turbidity (1.39% a.u.) of the extracted solutions was obtained by the autoclave heating method. The high performance liquid chromatography (HPLC) results also illustrated that the amounts of extracted saponin using autoclave, Bain-Marie and microwave heating extraction methods were 14, 8.8 and 1.3 (intensity mV), respectively. The results obtained by HPLC were reconfirmed by Fourier transform infrared (FT-IR) analysis.

Published: April 2018

Abstract

Background
The purpose of this study was to investigate irisin and myostatin responses to acute high-intensity interval exercise.

Materials and methods
Ten male professional kick-boxers aged between 18 and 24 years and 10 sedentary males with similar age and body weight participated in the present study. Participants performed 4 × 30-s Wingate test separated with 4 min of rest. Blood samples were taken immediately before and after exercise, and 3 and 6 h of recovery.

Results and conclusion
At rest, irisin levels were higher in the kick-boxers (p < 0.05). Immediately after the exercise, irisin levels were decreased in both groups (p < 0.05). A trend toward a return to baseline appeared after 3 h of recovery in the kick-boxers (p < 0.05). At rest, myostatin concentrations were not different between the groups (p > 0.05). Immediately after the exercise, myostatin levels were increased in both groups (p < 0.05). A trend toward a return to baseline appeared after 3 h of recovery in the kick-boxers (p < 0.05). Acute high-intensity interval exercise decreased irisin levels and increased myostatin levels.

Abstract
The generation of authentic mouse-models for human α1-antitrypsin (A1AT)-deficiency is difficult due to the high complexity of the mouse Serpina1 gene locus. Depending on the exact mouse strain, three to five paralogs are expressed, with different proteinase inhibitory properties. Nowadays with CRISPR-technology, genome editing of complex genomic loci is feasible and could be employed for the generation of A1AT-deficiency mouse models. In preparation of a CRISPR/Cas9-based genome-engineering approach we identified cDNA clones with a functional CDS for the Serpina1-paralog DOM-7. Here, we show that DOM-7 functionally inhibits neutrophil elastase (ELANE) and chymotrypsin, and therefore needs to be considered when aiming at the generation of A1AT-deficient models.

Published: April 2018

AbstractA thorough understanding of hot deformation behavior plays a vital role in determining process parameters of hot working processes. Firstly, uniaxial tensile tests have been performed in the temperature ranges of 150 °C–600 °C and strain rate ranges of 0.0001–0.01s−1 for analyzing the deformation behavior of ASS 304 and ASS 316. The phenomenological-based constitutive models namely modified Fields–Backofen (m-FB) and Khan–Huang–Liang (KHL) have been developed. The prediction capability of these models has been verified with experimental data using various statistical measures. Analysis of statistical measures revealed KHL model has good agreement with experimental flow stress data. Through the flow stresses behavior, the processing maps are established and analyzed according to the dynamic materials model (DMM). In the processing map, the variation of the efficiency of the power dissipation is plotted as a function of temperature and strain rate. The processing maps results have been validated with experimental data.
Creation of a Short Version of the User Experience Questionnaire UEQ
Authors: Alberola Catherine , Walter Götz , Brau Henning 
Published: April 2018

Abstract
This article focuses on the creation of a short version of the User Experience Questionnaire (UEQ). The goal is to reduce the number of 26 items significantly, allowing more efficient measurement of a product’s user experience (UX) while sustaining the high reliability and validity of the original questionnaire. The shortening will be based on a data set from a company in the home appliance industry which included 1534 participants. A reliable short version of the quantitative measuring instrument was developed using factor and reliability analyzes. This new version comprises only 11 items, has a high reliability and covers all dimensions of the original instrument. Correlations between the dimensions of the UX and various questions regarding user satisfaction indicate a high criterion validity of the UEQ short version. This new short version can help prevent participant fatigue during a test session when repeated application of the questionnaire is necessary to account for testing of multiple prototypes.
The Influence of User Interface Attributes on Aesthetics
Authors: Schmidt Thomas , Wolff Christian 
Published: April 2018

Abstract
In this paper we present an empirical study among 40 participants which investigates the relationship between various factors of user interface aesthetics on the one hand, and the influence of the user interface attributes, symmetry, colorfulness as well as visual complexity on user interface aesthetics on the other hand. The user interface aesthetics will be classified in intuitive aesthetics (1st impression with a presentation time of 500 ms) and reflective aesthetics (reflective long-term impression after a longer presentation). Reflective aesthetics is further classified in classical aesthetics (common attractiveness) as well as expressive aesthetics (creativity). For this study we have set up a corpus of 30 websites which are used as stimulus material. In a multi-step lab experiment, participants rate aesthetics and their subjective impression concerning user interface attributes using questionnaires. We are able to show that the intuitive aesthetic judgment correlates strongly with the reflective judgment. The symmetry of a website positively correlates with all definitions of aesthetics, especially with the classical or traditional interpretation in the sense of attractiveness. Visual complexity can be seen as the strongest predictor for the aesthetic judgement of users and it negatively correlates with all definitions. Concerning colorfulness, a preference for websites of a medium degree of colorfulness for the intuitive as well as the classical aesthetics can be stated. Concerning expressive aesthetics, websites of moderate to high colorfulness receive the best judgments. The relationships which we have found are finally discussed in the context of previous research and some implications for future user interface design are given.

Abstract
The structural characteristics of lotus (Nelumbo nucifera Gaertn.) seeds preserved by microwave vacuum drying (MVD) were investigated under various drying parameters, including microwave power density and vacuum degree. Dried lotus seeds were examined for microstructure by field emission scanning electron microscopy. Fractal dimension of the microscopic images was calculated by the box counting method. The apparent physical changes of the seeds, namely shrinkage ratio, rehydration rate, and hardness index, were determined to correlate well with their microstructural changes computed by the normalized changes of the fractal dimension (ΔFD/FD0). The samples at −90 kPa, 15 W/g exhibited a lower shrinkage ratio (46.2 %), higher rehydration rate (187.5 %) and lower hardness (3692.4 N). Although the physical and microstructural changes of the samples prepared by different drying methods (MVD, microwave drying, and hot air drying) varied, the changes of the ΔFD/FD0 of the dried samples exhibited the same trends.
Translation as a sub-set of public and social policy and a consequence of multiculturalism: the provision of translation and interpreting services in Australia
Authors: Hlavac Jim , Gentile Adolfo , Orlando Marc , Zucchi Emiliano , Pappas Ari 
Published: April 2018

AbstractTranslation can be an overt feature of public policy, typically in situations where there are status planning regulations that prescribe the use of two or more languages that then enable the development of translation infrastructure. In New World countries, one language, usually that of a former colonial power, is thede jureorde factoofficial language and seldom does translation feature as a national policy in its own right. Accounts for the provision of translation in a country such as Australia are to be found elsewhere. This article adopts a “looking sideways” approach to account for the provision of translation in a range of settings – healthcare, welfare, court/police, etc. In these areas, and since the introduction ofmulticulturalismin the mid-1970s, linguistic diversity of the Australian populace has been a component of policy formulation and the provision of translation has become a means for policy to be implemented. A national policy on languages that expressly includes translation does exist in Australia. However, it is the cross-portfolio convention of addressing language barriers in the provision of government services and beyond that accounts for translation. It is here conceptualized not so much as a cultural-linguistic value, but as a means for service delivery.

Published: April 2018

AbstractNecrotizing enterocolitis (NEC) remains the leading cause of gastrointestinal surgical emergency in preterm neonates. Over the last five decades, a variety of experimental models have been developed to study the pathophysiology of this disease and to test the effectiveness of novel therapeutic strategies. Experimental NEC is mainly modeled in neonatal rats, mice and piglets. In this review, we focus on these experimental models and discuss the major advantages and disadvantages of each. We also briefly discuss other models that are not as widely used but have contributed to our current knowledge of NEC.
Improved serotonergic neurotransmission by genistein pretreatment regulates symptoms of obsessive-compulsive disorder in streptozotocin-induced diabetic mice
Authors: Phadnis Pradeep , Dey Sarkar Purnima , Rajput Mithun Singh 
Published: April 2018

Abstract

Background
Initial evidences have shown that diabetes mellitus occurs concomitantly with obsessive-compulsive disorder (OCD) symptomatology. Serotonergic psychiatric therapy posits that serotonin is a central character in the management of OCD. Hence, it is worth investigating novel chemical entities affecting the serotonergic system for targeting OCD. An isoflavonoid phytoestrogen, genistein, has been recognized as of great pharmacological value especially for protecting neurodegeneration, depression (serotonin regulation), and diabetes. The effectiveness of genistein pretreatment on the symptoms of OCD in streptozotocin-induced diabetic mice is investigated in this study. We also evaluate the probable involvement of the serotonergic system.

Methods
Groups of diabetic mice were treated with genistein at the dose of 5.0 and 10.0 mg/kg (intraperitoneal, twice daily, 14 days), and symptoms of OCD were assessed by the marble-burying behavior, in comparison with the standard drug fluoxetine. Neurochemical assessment of the serotonergic ratio 5-hydroxyindole-3-methoxyphenylacetic acid/5-hydroxytryptamine (5-HIAA/5-HT) in the cortical region of the brain was performed using HPLC (high-pressure liquid chromatography).

Results
Chronic treatment with genistein significantly recovered [F(6, 35)=53.00, p<0.0001, R
2=0.9008] the symptoms of OCD as assessed by marble burying behavior in normal and diabetic mice. Locomotor performance was not influenced by the diabetic condition or any associated treatment. The turnover of serotonin neurotransmission (5-HIAA/5-HT) was significantly boosted in the diabetic condition; genistein treatment dragged it [F(6, 35)=35.75, p<0.0001, R
2=0.8597] toward the respective control.

Conclusions
Genistein supplementation might be a potential therapeutic line for the management and/or prevention of diabetes-associated OCD symptomatology.
Does Compressing High School Duration Affect Students’ Stress and Mental Health? Evidence from the National Educational Panel Study
Authors: Sophie Quis Johanna 
Published: April 2018

AbstractStarting in 2004/2005, the German state Baden-Wurttemberg reduced academic track duration from nine to eight years, leaving cumulative instruction time mostly unchanged. I use this change in schooling policy to identify the effect of increased schooling intensity on students’ internalizing mental health problems and perceived stress. Using data on 2306 students from the Additional Study Baden-Wurttemberg of the National Educational Panel Study (NEPS), estimates show strong negative effects on internalizing mental health problems for girls and an increase in stress for both genders.
