Crystal structure instability of FeSe grains: Formation of non-superconducting phase at the grain surface
Authors: Izawa Hiroki , Tanaka Yuji , Mizuguchi Yoshikazu , Miura Osuke 
Published: April 2016

Abstract
We investigated the magnetization and crystal structure of FeSe polycrystalline samples with various grain sizes. For the samples with large grains, a large magnetic critical current density J
c was observed. For the samples with small grains, superconductivity signals were not observed; instead, magnetization hysteresis, which is not a result of superconductivity, was observed. In the X-ray diffraction pattern for the samples with small grains, broad additional peaks were observed, corresponding to the formation of the non-superconducting (monoclinic) Fe–Se phase at the FeSe grain surface. The crystal structure instability at the grain surface would be the reason for the low superconducting properties of the Fe-chalcogenide polycrystalline wires investigated thus far.

Published: April 2016

Abstract
We report on the material and optical properties of core–shell InGaN layers grown on GaN nanorod arrays. The core–shell InGaN layers were well grown on polarization-reduced surfaces such as semipolar pyramids and nonpolar sidewalls. In addition, to compensate the biaxial strain between GaN and InGaN layers, we grew interlayers underneath a thick InGaN layer. Here, the interlayers were composed of multiple superlattice structures. We could observe that the indium composition of core–shell InGaN structures increased with the number of interlayers. This indicates that the absorption energy band of InGaN alloys can be better matched to the spectral irradiance of the solar spectrum in nature. We also implemented a simulation of Ga-polar and nonpolar InGaN-based solar cells based on the indium composition obtained from the experiments. The result showed that nonpolar InGaN solar cells had a much higher efficiency than Ga-polar InGaN solar cells with the same thickness of the absorption layer.
The Content of Beginning Special Educators' Conversations with Their Electronic Mentors
Authors: Gentry Roberta 
Published: April 2016

Abstract
This exploratory study examined the frequency and content of text-based interactions between special education mentors (n=22) and mentees (n=50) within the Electronic Mentoring for Student Success Program (eMSS). Perceived outcomes of participants, based on an open ended survey question, were also analyzed. The Interstate Teacher Assessment and Support Continuum (InTASC) Model Core Standards (2011) were used to qualitatively code the conversations between novice teachers and their mentors. Support for all standards was found with learning environments (n=850), professional learning and ethical practices (n=878), and leadership and collaboration (n=906) being the most common topics of discussion. However, several standards (i.e. assessment and content knowledge) were difficult to code because demonstration is required which cannot be observed in an asynchronous site. Frequency of interactions revealed a surprising result that mentors posted (n=675) twice as often as mentees (n=322). Mentees reported perceived outcomes in three main areas: collaboration, pedagogical knowledge, and emotional support.

Published: April 2016

AbstractTraditional jet‐in‐air cell sorters have been designed and optimized to isolate small particles such as mammalian lymphocytes with an average diameter of 10 μm. We discuss the practical considerations of setting up a conventional jet‐in‐air cell sorter, using a 200‐μm nozzle, to isolate the large parasitic nematode eggs of Nippostrongylus brasiliensis, with a maximum size of 60 μm. The eggs were separated based on light scattering properties, no fluorescent dye or molecule was required. © 2016 by John Wiley & Sons, Inc.

Characteristics and consequences of medical care interruptions in HIV-infected patients in France
Authors: CUZIN L. , DELLAMONICA P. , YAZDANPANAH Y. , BOUCHEZ S. , REY D. , HOEN B. , CABIÉ A. ,   for the Dat'AIDS Study Group
Published: April 2016

SUMMARYTo describe the consequences of medical care interruptions (MCIs) we selected patients with at least two medical encounters between January 2006 and June 2013 in the Dat'AIDS cohort. Patients with any time interval >15 months between two visits were defined as having a MCI, as opposed to uninterrupted follow-up (UFU). Patients’ characteristics at the time of HIV diagnosis and at the censoring date were compared between groups. Cox proportional hazards models were built to assess the role of interruptions on survival (total and AIDS-free). Of 11 116 patients, 824 had at least one MCI. These patients were younger at the time of HIV diagnosis (30vs. 33 years,P< 0·0001). MCI was less frequent in men having sex with menvs.heterosexual patients [odds ratio (OR) 0·81, 95% confidence interval (CI) 0·69–0·96)], and a centre effect was described. MCI was independently associated with AIDS (OR 2·54, 95% CI 2·10–3·09) and death (OR 2·65, 95% CI 1·94–3·61). At the censoring date, 52·2% of patients with at least one MCI had viral load below detectionvs.85·3% of the UFU group (P< 0·0001). In conclusion, MCIs were associated with patients’ survival and with the proportion of viral loads below detection in our cohort, compromising individual and collective treatment benefits.
Early suppression effect in human primary visual cortex during Kanizsa illusion processing: A magnetoencephalographic evidence
Authors: CHERNYSHEV BORIS V. , PRONKO PLATON K. , STROGANOVA TATIANA A. 
Published: April 2016

AbstractDetection of illusory contours (ICs) such as Kanizsa figures is known to depend primarily upon the lateral occipital complex. Yet there is no universal agreement on the role of the primary visual cortex in this process; some existing evidence hints that an early stage of the visual response in V1 may involve relative suppression to Kanizsa figures compared with controls. Iso-oriented luminance borders, which are responsible for Kanizsa illusion, may evoke surround suppression in V1 and adjacent areas leading to the reduction in the initial response to Kanizsa figures. We attempted to test the existence, as well as to find localization and timing of the early suppression effect produced by Kanizsa figures in adult nonclinical human participants. We used two sizes of visual stimuli (4.5 and 9.0°) in order to probe the effect at two different levels of eccentricity; the stimuli were presented centrally in passive viewing conditions. We recorded magnetoencephalogram, which is more sensitive than electroencephalogram to activity originating from V1 and V2 areas. We restricted our analysis to the medial occipital area and the occipital pole, and to a 40–120 ms time window after the stimulus onset. By applying threshold-free cluster enhancement technique in combination with permutation statistics, we were able to detect the inverted IC effect—a relative suppression of the response to the Kanizsa figures compared with the control stimuli. The current finding is highly compatible with the explanation involving surround suppression evoked by iso-oriented collinear borders. The effect may be related to the principle of sparse coding, according to which V1 suppresses representations of inner parts of collinear assemblies as being informationally redundant. Such a mechanism is likely to be an important preliminary step preceding object contour detection.
Learning the Value of Rights: Abortion Politics and the Liberalization of Evangelical Free Speech Advocacy
Authors: Lewis Andrew R. 
Published: April 2016

AbstractFor the past century, the expansion of free speech rights has been the domain of liberals. Recently, however, conservatives have become advocates for expanded free speech rights. For Evangelicals Protestants, this advocacy would have been highly controversial only a generation ago, offending the base's ordered liberty sentiments. I suggest that abortion politics is a primary contributor to the evangelical free speech advocacy shift. Using a variety of data, I detail the evangelical shift toward expanded free speech by exploring the topics of radical protest, campaign finance, and obscenity. While rank-and-file evangelicals are less supportive of free speech than the general-public, elites have routinely used abortion politics to frame the shift toward individual free speech rights. Elites have diverged from their constituents to support a higher-priority issue (abortion), and the constituents have been supportive. Abortion politics has come to dominate evangelical advocacy decisions and has cultivated an evangelical rights culture.
Symmetry-protected ideal Weyl semimetal in HgTe-class materials
Authors: Ruan Jiawei , Jian Shao-Kai , Yao Hong , Zhang Haijun , Zhang Shou-Cheng , Xing Dingyu 
Published: April 2016

AbstractIdeal Weyl semimetals with all Weyl nodes exactly at the Fermi level and no coexisting trivial Fermi surfaces in the bulk, similar to graphene, could feature deep physics such as exotic transport phenomena induced by the chiral anomaly. Here, we show that HgTe and half-Heusler compounds, under a broad range of in-plane compressive strain, could be materials in nature realizing ideal Weyl semimetals with four pairs of Weyl nodes and topological surface Fermi arcs. Generically, we find that the HgTe-class materials with nontrivial band inversion and noncentrosymmetry provide a promising arena to realize ideal Weyl semimetals. Such ideal Weyl semimetals could further provide a unique platform to study emergent phenomena such as the interplay between ideal Weyl fermions and superconductivity in the half-Heusler compound LaPtBi.
