Exploratory cell dynamics: a sense of touch for cells?
Authors: Nalbant Perihan , Dehmelt Leif 
Published: April 2018

Abstract
Cells need to process multifaceted external cues to steer their dynamic behavior. To efficiently perform this task, cells implement several exploratory mechanisms to actively sample their environment. In particular, cells can use exploratory actin-based cell protrusions and contractions to engage and squeeze the environment and to actively probe its chemical and mechanical properties. Multiple excitable signal networks were identified that can generate local activity pulses to control these exploratory processes. Such excitable signal networks offer particularly efficient mechanisms to process chemical or mechanical signals to steer dynamic cell behavior, such as directional migration, tissue morphogenesis and cell fate decisions.
Constitutional Jurisdiction in a Democracy Governed by the Rule of Law
Authors: Holzinger Gerhart 
Published: April 2018

Abstract
Today, the Austrian Constitutional Court looks back on an eventful history. The Austrian model of constitutional adjudication attracted wide attention, in particular after World War II and proved to be a success story. Carefully managing both the influences of the ECHR and, most recently, those of European Union law, the Court has become an active player in the dialogue of the courts involved.
Pragmatic challenges in the communication of emotions in intercultural couples
Authors: Dewaele Jean-Marc 
Published: April 2018

Abstract
Statistical analysis of quantitative and qualitative data collected via an online questionnaire from 429 participants who were in an intercultural relationship revealed strongly divided opinions on the pragmatic challenges of communicating emotions with their partner. Though most participants reported some degree of difficulty, most agreed that love and emotional acculturation helped them overcome language barriers. Difficulties in communication were attributed to linguistic, pragmalinguistic and sociopragmatic issues by almost three quarters of the participants who filled out an open question. Participants with higher scores on Emotional Stability, Flexibility and – marginally – Openmindedness, male participants and participants with high levels of education reported fewer difficulties. Partners in intercultural couples thus faced serious and sometimes totally unexpected pragmatic challenges in communicating emotions but generally managed to overcome the obstacles after some months.

Published: April 2018

AbstractWe propose, design, fabricate and characterize a subwavelength grating slot (SWGS) waveguide on silicon platform at short-wave infrared (SWIR) wavelength of 2 μm. The mode guiding mechanism, i.e. SWGS mode, is a combination of surface-enhanced supermode and Bloch mode. We also design and fabricate a low-loss strip-to-SWGS mode converter. We further demonstrate chip-scale direct modulation data transmission at 2 μm through the fabricated SWGS waveguides. Favorable operation performance is achieved in the experiment.
Huygens’ metasurfaces from microwaves to optics: a review
Authors: Chen Michael , Kim Minseok , Wong Alex M.H. , Eleftheriades George V. 
Published: April 2018

AbstractIn this article, the basic principles and the main applications of Huygens’ metasurfaces (HMSs) are reviewed from microwaves to optics. In general, HMSs comprise a thin layer of orthogonal electric and magnetic dipoles, which form an array of Huygens’ sources. In a refraction setting, these sources radiate mostly in the forward direction and can be used to manipulate an incident electromagnetic wave at will. In the case of passive HMSs, the Huygens’ sources are induced by an incident electromagnetic field. Examples of passive manipulations include reflectionless refraction, perfect anomalous reflection, and arbitrary antenna beam forming. In the case of active HMSs, the Huygens’ sources are impressed active sources. Active HMS manipulations include cloaking and subwavelength spot formation in a cavity environment.
Global Cities and the Ends of Globalism
Authors: Curtis Simon 
Published: April 2018

AbstractThe global city has been both a product and driver of contemporary globalization. But today the global city is under threat from at least two directions. Firstly, despite their astonishing economic growth over the last four decades, they have become deeply divided and polarized in ways that threaten the integrity of the urban fabric. The second source of threat comes from the weakening of liberal world order. This article argues that global cities are at a point of crisis, because they embody an unstable form of global market society. In order to survive in a ‘global’ form, they will need to evolve by repurposing some of the political, economic and governance capacities that they have been developing over the last four decades. The article asks: what capacities and capabilities have global cities generated, and how might they be reoriented in the creation of alternative global city futures?
Growth, yield attributes and yield of irrigated spring wheat as influenced by sowing depth

Published: April 2018

Abstract
In South Asia, including Bangladesh, most farmers sow wheat under residual soil moisture after rice is harvested, but the upper layer of soil dries quickly after soil has been prepared for wheat sowing. Crop seeds that are sown either deeply or shallowly can result in failed emergence, low dry matter accumulation, and reduced grain yield. Therefore, appropriate sowing depth is crucial for seedling emergence and successful crop establishment. Considering this, a two-year field experiment was conducted at the research field of the Agricultural Research Station of the Bangladesh Agricultural Research Institute at Dinajpur during the dry, rabi (winter) season of 2013-14 and 2014-15, at four sowing depths, i.e., 2, 4, 6 and 8 cm, to identify the most appropriate sowing depth for higher grain yield. Wheat seeds sown at a depth of 4 cm resulted in significantly highest number of seedlings and seminal roots, tallest plants as well as largest roots and plant biomass followed by sowing at a depth of 6, or 2 cm. Depth of sowing also significantly affected the yield and yield-related attributes, all performing best at a depth of 4 cm. The highest number of spikes m-2, grain yield, straw yield and harvest index were observed when seeds were sown at depths of 4 or 6 cm, relative to 2 or 8 cm. Therefore, a sowing depth of 4 to 6 cm is recommended for wheat cultivation in South Asia, including Northern Bangladesh.
Transient Spectroscopy of Glass-Embedded Perovskite Quantum Dots: Novel Structures in an Old Wrapping

Published: April 2018

Abstract
Semiconductor doped glasses had been used by the research and engineering communities as color filters or saturable absorbers well before it was realized that their optical properties were defined by tiny specs of semiconductor matter known presently as quantum dots (QDs). Nowadays, the preferred type of QD samples are colloidal particles typically fabricated via organometallic chemical routines that allow for exquisite control of QD morphology, composition and surface properties. However, there is still a number of applications that would benefit from the availability of high-quality glass-based QD samples. These prospective applications include fiber optics, optically pumped lasers and amplifiers and luminescent solar concentrators (LSCs). In addition to being perfect optical materials, glass matrices could help enhance stability of QDs by isolating them from the environment and improving heat exchange with the outside medium. Here we conduct optical studies of a new type of all-inorganic CsPbBr3 perovskite QDs fabricated directly in glasses by high-temperature precipitation. These samples are virtually scattering free and exhibit excellent waveguiding properties which makes them well suited for applications in, for example, fiber optics and LSCs. However, the presently existing problem is their fairly low room-temperature emission quantum yields of only ca. 1%–2%. Here we investigate the reasons underlying the limited emissivity of these samples by conducting transient photoluminescence (PL) and absorption measurements across a range of temperatures from 20 to 300K. We observe that the low-temperature PL quantum yield of these samples can be as high as ~25%. However, it quickly drops (in a nearly linear fashion) with increasing temperature. Interestingly, contrary to traditional thermal quenching models, experimental observations cannot be explained in terms of a thermally activated nonradiative rate but rather suggest the existence of two distinct QD sub-ensembles of “emissive” and completely “nonemissive” particles. The temperature-induced variation in the PL efficiency is likely due to a structural transformation of the QD surfaces or interior leading to formation of extremely fast trapping sites or nonemissive phases resulting in conversion of emissive QDs into nonemissive. Thus, future efforts on improving emissivity of glass-based perovskite QD samples might focus on approaches for extending the range of stability of the low-temperature highly emissive structure/phase of the QDs up to room temperature.
Rationally Derived Three-Parameter Models for Elastomeric Suspension Bushings: Theory and Experiment
Authors: Kanchwala Husain , Chatterjee Anindya 
Published: April 2018

Abstract
Linear, causal, and time-invariant viscoelastic material response models are of practical interest in many areas, including our interest in automotive suspension bushings. Empirical fits to experimental data may involve several fitted parameters which, if chosen arbitrarily, violate theoretical restrictions derived from causality, linearity, and time invariance. Here, we retain a correction term in an asymptotic expansion for Bode’s representation of the famous Kramers-Kronig relations. We then derive two new mathematical forms that both satisfy theoretical restrictions and fit experimental data well. Both forms proposed in this article have three free parameters each. The first form has logarithms and power law terms and is valid if the index in the power law is small. The second form has only logarithmic terms and satisfies restrictions exactly. Both forms successfully fit the test data for four different automotive suspension bushings in a frequency range of 1–30 Hz. The first form, with the power law, is more complicated but fits the data slightly better. Because the frequency response involves both a real and imaginary part, simultaneously fitting both parts well with merely three parameters validates the approximations proposed in this article.
Of Dancing Girls and Sarabandes
Authors: Pruiksma Rose 
Published: April 2018

The French sarabande is typically characterized as one of the most serious and noble baroque dances in the instrumental suite. New research synthesizing eyewitness accounts, literary sources, and musical analysis reveals the sarabande’s rich history as a theatrical dance regularly performed by female dancers in French court ballets. The groups of girls and solo young women who danced it between 1651 and 1669 invite us to reshape our narrative of the sarabande in France.
Both literary references and the theatrical context reveal how the sarabande resonated with layers of culturally inscribed meanings at a time when danced and non-danced sarabandes coexisted side by side. The same individuals moved easily between dancing, watching danced sarabandes in ballets, and playing sarabandes on the keyboard or lute. Spectators and listeners likewise encountered and interpreted sarabandes in multiple settings; knowledge gained through dancing or accompanying dancing did not simply disappear from one performance context to the next. While such embodied knowledge is no longer common cultural currency, examining the historically embodied presence of the sarabande and its ties to female dancers permits a better understanding of its cultural resonances and its appeal in the seventeenth century and opens up a wider range of interpretations of this multi-faceted, multivalent dance type.

SummaryHypogonadotrophic hypogonadism is due to impaired or reduced gonadotrophin secretion from the pituitary gland. In the absence of any anatomical or functional lesions of the pituitary or hypothalamic gland, the hypogonadotrophic hypogonadism is referred to as idiopathic hypogonadotrophic hypogonadism (IHH). We present a case of a young lady born to consanguineous parents who was found to have IHH due to a rare gene mutation.Learning points:The genetic basis of a majority of cases of IHH remains unknown.IHH can have different clinical endocrine manifestations.Patients can present late to the healthcare service because of unawareness and stigmata associated with the clinical features.Family members of affected individuals can be affected to varying degrees.

Published: April 2018

This paper is concerned with the problem of nonfragile mixed H∞ and passivity control for neural networks with successive time-varying delay components. We construct a suitable Lyapunov–Krasovskii function with triple and quadruple integral terms then utilizing Jensen's lemma and Wirtinger-type inequality technique. Some sufficient conditions are presented for the existence of nonfragile mixed H∞ and passivity performance criterions. The expressions for the nonfragile controller can be obtained by solving a set of linear matrix inequality. Finally, two numerical examples are presented to demonstrate the effectiveness of our proposed method.
Iterative unique positive solutions for singular p-Laplacian fractional differential equation system with several parameters
Authors: Guo Limin , Liu Lishan , Wu Yonghong 
Published: April 2018

By using the method of reducing the order of a derivative, the higher-order fractional differential equation is transformed into the lower-order fractional differential equation and combined with the mixed monotone operator, a unique positive solution is obtained in this paper for a singular p-Laplacian boundary value system with the Riemann–Stieltjes integral boundary conditions. This equation system is very wide because there are many parameters, which can be changeable in the equation system in this paper, and the nonlinearity is allowed to be singular in regard to not only the time variable but also the space variable. Moreover, the unique positive solution that we obtained in this paper is dependent on λ, and an iterative sequence and convergence rate are given, which are important for practical application. An example is given to demonstrate the application of our main results.

Abstract

Objectives
This retrospective cohort study evaluated the impact of the Stress Check Program, a recently introduced national policy and program aimed at reducing psychological distress among Japanese workers.

Methods
A baseline survey was conducted from November 2015 to February 2016, the period when Japan began enforcing the Stress Check Program. A one-year follow-up survey was conducted in December 2016. In the follow-up survey, two exposure variables were collected: having taken the annual stress survey, and experiencing an improvement in the psychosocial work environment. Psychological distress was assessed using the Brief Job Stress Questionnaire (BJSQ) at baseline and 1-year follow-up. The two exposure variables were used to define four groups: “Neither”, “Stress survey (SS) only ”, “Psychosocial work environment improvement (WI) only”, and “Both”. BJSQ results were analyzed using repeated measures general linear modeling (GLM).

Results
The study included 2,492 participants: 1,342 in the “Neither” group, 1,009 in the “SS only” group, 76 in the “WI only” group, and 65 in the “Both” group. Overall time-group interaction effects were not significant. The “Both” group showed significantly greater improvements in psychological distress than the “Neither” group (p = 0.02) at the 1-year follow-up, although the effect size was small (d = -0.14).

Conclusions
Combination of the annual stress survey and improvement in psychosocial work environment may have been effective in reducing psychological distress in workers, although the effect size was small.

Published: April 2018

Abstract

Objectives
Rotating shift work has been reported to increase the risk of cardiovascular diseases. Vascular endothelial dysfunction and platelet activation are among the leading causes of thrombus formation in patients with myocardial infarction or stroke. Endothelial function has been shown to be impaired immediately after night-shift work; however, it is not known whether platelets are also activated. The aim of this study was to investigate the acute impact of night-shift work on platelet function.

Methods
This observational study included 11 healthy medical staff members (seven women, median age 32 years). We examined each subject’s platelet aggregation rates and the serum concentrations of eicosanoid mediators after night-shift work and on dayshift work without preceding night-shift work (baseline).

Results
Platelet aggregation did not differ from baseline levels after night-shift work. However, serum cyclooxygenase (COX)-metabolized eicosanoid mediators, particularly thromboxane (Tx) B2 (a stable metabolite of TxA2 and the most important marker of platelet activation), were significantly higher after the night-shift than at baseline (median 65.3 vs 180.4 ng/ml).

Conclusions
Although platelet aggregation did not increase, there was an increase in serum COX-metabolized eicosanoid mediators such as TxB2 in healthy medical staff after nightshift work. This platelet hypersensitivity may be one of the mechanisms underlying the significant association between night-shift work and adverse cardiovascular outcomes.
Rock opera and resistance
Authors: Bülgözdi Imola , Réti Zsófia 
Published: April 2018

Stephen, the King (1983), the most popular Hungarian rock opera, succeeded in bringing alive the well-known foundational myth of the Hungarian nation state by means of a new genre and its political relevance as a covert protest against the Soviet military presence. The rock opera was also extremely popular among members of Hungarian communities beyond the borders. The article compares two, very different cases of trans-border Hungarian identities focused around Stephen, the King: the Transylvanian reception of the rock opera and, based on Réka Pigniczky’s documentary Incubator, its American-Hungarian readings. The latter qualifies as a hybrid identity in progress, while Transylvania, a site of permanent cultural and political friction between Hungary and Romania, displays a cultural identity that is inherently mixed, a borderland identity. Capitalizing on Stuart Hall’s understanding of cultural identities, we argue that the diasporic/minority reception of the rock opera enabled unique ways of imag(in)ing national belonging, which were, to a great extent, different from its reception in Hungary. Our case studies confirm that both diasporic and borderland identities have received a boost via the new popular genre, enabling both groups to forge bonds with the imagined community of Hungarians and what they perceived as Hungarian national culture.
Are Teachers Paying Enough Attention to Low-achieving Students While Teaching Reading Strategies?
Authors: Sičiūnienė Viktorija , Toleikytė Nijolė 
Published: April 2018

The article presents the results of the qualitative research on the attitude of teachers towards low-achieving students while teaching reading strategies. Such scientific studies have not been conducted in Lithuania before. This was the first research, which aimed to identify if the teachers allocated attention to low-achieving school learners while reflecting on the process of teaching/ learning reading strategies and the achieved results.
The sample of the research included 33 teachers from Lithuanian schools. They were participants in the national project “Learning Teachers – Learning Students” in 2015–2016. For two years it was observed how teachers in cooperating teams learned to apply reading strategies and provided collegial feedback to each other. The authors of the article were experts, who prepared diagnostic tests measuring reading skills, provided recommendations to the teachers how to apply methodology for teaching reading strategies, to measure and analyse reading achievements.
The research results revealed that not all the teachers of the Lithuanian language and mathematics repeatedly measured reading skills of their learners. The teachers’ responses show that the total dynamics of results of project schools is evaluated positively but in separate cases it is quite ambiguous. It was noticed that evaluating the dynamics of reading results, the focus is laid more on the average indicator in the class and too little attention is paid to monitoring and analysis of the results of separate learner groups, and on those of low-achieving students in particular, as well as to individual progress of learners. Analysing the teachers’ reflections on how decisions/agreements about application of specific reading strategies are made, it can be stated that collegial feedback, agreements at school level and colleagues support was particularly important to teachers but it lacked a focused orientation, too little attention was dedicated to observation and discussion of practice of reading strategy application.
