Published: June 2017

AbstractFabrication of the out-of-plane atomically sharp p–n junction by stacking two dissimilar two-dimensional materials could lead to new and exciting physical phenomena. The control and tunability of the interlayer carrier transport in these p–n junctions have a potential to exhibit new kind of electronic and optoelectronic devices. In this article, we present the fabrication, electrical, and opto-electrical characterization of vertically stacked few-layers MoTe2(p)–single-layer MoS2(n) heterojunction. Over and above the antiambipolar transfer characteristics observed similar to other hetero p–n junction, our experiments reveal a unique feature as a dip in transconductance near the maximum. We further observe that the modulation of the dip in the transconductance depends on the doping concentration of the two-dimensional flakes and also on the power density of the incident light. We also demonstrate high photo-responsivity of ~105 A/W at room temperature for a forward bias of 1.5 V. We explain these new findings based on interlayer recombination rate-dependent semi-classical transport model. We further develop first principles-based atomistic model to explore the charge carrier transport through MoTe2–MoS2 heterojunction. The similar dip is also observed in the transmission spectrum when calculated using density functional theory–non-equilibrium Green’s function formalism. Our findings may pave the way for better understanding of atomically thin interface physics and device applications.
The Persistence and Functional Impact of English Language Difficulties Experienced by Children Learning English as an Additional Language and Monolingual Peers
Authors: Whiteside Katie E. , Norbury Courtenay Frazier 
Published: June 2017

Purpose
This study explored whether a monolingual-normed English language battery could identify children with English as an additional language (EAL) who have persistent English language learning difficulties that affect functional academic attainment.

Method

Children with EAL (
n
= 43) and monolingual English-speaking children (
n
= 46) completed a comprehensive monolingual-normed English language battery in Year 1 (ages 5–6 years) and Year 3 (ages 7–8 years). Children with EAL and monolingual peers, who either met monolingual criteria for language impairment or typical development on the language battery in Year 1, were compared on language growth between Year 1 and Year 3 and on attainment in national curriculum assessments in Year 2 (ages 6–7 years).

Results
Children with EAL and monolingual peers who met monolingual criteria for language impairment in Year 1 continued to display comparably impaired overall language ability 2 years later in Year 3. Moreover, these groups displayed comparably low levels of academic attainment in Year 2, demonstrating comparable functional impact of their language difficulties.

Conclusion
Monolingual-normed language batteries in the majority language may have some practical value for identifying bilingual children who need support with language learning, regardless of the origin of their language difficulties.
Effective radiation pattern concept for wireless systems analysis
Authors: Zarbouti D.A. , Tsoulos G.V. , Athanasiadou G.E. 
Published: June 2017

In this Letter, the use of the effective radiation pattern (ERP) concept for wireless systems analysis is proposed, in order to account for multipath angular spread effects upon ideal antenna radiation patterns. The method for producing the ERP that optimally models any real antenna radiation pattern is presented and the proof of concept is demonstrated via large‐scale simulations for a multicellular beamforming system. Results show that the accuracy in SIR calculations is better than 1 dB.
Endurance of magnetic tunnel junctions under dynamic voltage stress
Authors: Choi C.M. , Sukegawa H. , Mitani S. , Song Y.H. 
Published: June 2017

MgAl2O4 (MAO)‐based magnetic tunnel junctions (MTJs) with an MAO thickness of ∼1.25 nm are fabricated and their cycling characteristics under dynamic voltage stress are evaluated. The speed of breakdown strongly depended on the pulse polarities used, bipolar, positive (+) unipolar, and negative (−) unipolar. The bipolar condition yielded more rapid breakdown under cycling. Between the two unipolar conditions, positive bias yielded more rapid breakdown than negative bias; the difference between these is understood to arise from the conditions of the interface between the MAO and ferromagnetic layers. Among apparently normal MTJ cells showing little resistance drift, 20% were degraded during a long cycling test in the bipolar stress condition. Thus, the use of bipolar voltage stress is essential to screen for potentially defective MTJs, and the asymmetric condition at the interface is minimised by process control for application of the simple unipolar bias condition.
Seismic uncoupled analyses for offshore wind turbines
Authors: Santangelo Fabio , Failla Giuseppe , Arena Felice , Ruzzo Carlo 
Published: June 2017

For seismic assessment of wind turbines in seismically active areas, International Standards and Guidelines allow combining two separate analyses under environmental and earthquake loads, respectively. Time‐domain or response‐spectrum‐based analyses are prescribed to compute the separate earthquake response. While some work has already been done to estimate the accuracy of uncoupled analyses for land‐based wind turbines, to date no similar studies have been carried out for offshore ones. This paper investigates two different implementations of uncoupled analyses for seismic assessment of offshore wind turbines, considering the case study of a 5 MW wind turbine mounted on a tripod in intermediate waters.
Incorporating the Principles of Self-Management into Treatment of Dysarthria Associated with Parkinson's Disease
Authors: Baylor Carolyn , Britton Deanna , Yorkston Kathryn 
Published: June 2017

AbstractAlthough understanding patient perspectives on treatment is a major component of patient-centered care, little is known about patient perspectives related to dysarthria treatment in Parkinson's disease (PD). This article attempts to explore the perspective of patients with dysarthria associated with PD by interviewing them before and after treatment. Treatment expectations and experiences are summarized along with a discussion of how patients are using the tools they learned once treatment was completed. Comments about treatment were generally positive and suggested increased awareness and improved speech loudness. However, areas for improvement were also identified including: (1) treatment was not addressing some communication problems that were of concern to patients; (2) therapy programs were not enjoyable; and (3) it was difficult to maintain gains after therapy ended. Principles of self-management are reviewed to address some of the shortcomings of current treatment approaches.
Interdisciplinary Management of a Perforated Aneurysmal Arteria Lusoria: A Case Report
Authors: Rouman Mina , Petrovitch Alexander , Gey Eva-Maria , Kuntze Thomas 
Published: June 2017

Background An aberrant right subclavian artery (RSA) or arteria lusoria is the most common congenital abnormality of the aortic arch with an incidence of 0.3 to 3.0%.
Case Description We report a case of a perforated aneurysmal aberrant RSA, managed using a hybrid approach.
Conclusion In emergency cases with acute bleeding, we recommend an endovascular approach to avoid the lethal sequel of arterial leakage. Whenever possible, the pulsatile blood flow to the right arm should be restored. Management should be tailored to the nature of the aneurysmal aberrant RSA, patient's comorbidities, and concomitant lesions.
The shrug
Authors: Debras Camille 
Published: June 2017

AbstractThe shrug is a widely shared gesture ensemble with several different components. These include: lifting the shoulders; rotating the forearms outwards with extended fingers to a “palm up” position; with mouth firmly closed, pulling the lips downwards (the “mouth shrug”), which may or may not be combined with raising the eyebrows and tilting the head to one side. It comprises a rich yet consistent network of forms (a single component or a combination of components can index the whole enactment). These components, together or in various combinations, are shown to express incapacity, powerlessness, indetermination, indifference, obviousness which, we suggest, are unified by a common semantic theme of personal disengagement. Since the shrug expresses pragmatic meanings and its formational and semantic core remains stable across different contexts and speakers, the shrug also qualifies as a recurrent gesture. Based on empirical evidence gathered from a videotaped corpus of dyadic interactions between native speakers of British English, this study proposes a qualitative-yet-systematic method to provide a unified account of shrugging.
Study on reinforcement of soil for suppressing fugitive dust by bio-cementitious material
Authors: Zhan Qiwei , Qian Chunxiang 
Published: June 2017

Abstract
Microbial-induced reinforcement of soil, as a new green and environmental-friendly method, is being paid extensive attention to in that it has low cost, simple operation and rapid effects. In this research, reinforcement of soil for suppressing fugitive dust by bio-cementitious material was investigated. Soil cemented by bio-cementitious material had superior mechanical properties, such as hardness, compressive strength, microstructure, wind-erosion resistance, rainfall-erosion resistance and freeze-thaw resistance. The average hardness of sandy soil, floury soil and clay soil is 18.9 º, 25.2 º and 26.1 º, while average compressive strength of samples is 0.43 MPa, 0.54 MPa and 0.69 MPa, respectively; meanwhile, the average calcite content of samples is 6.85 %, 6.09 %, and 5.96 %, respectively. Compared with the original sandy soil, floury soil and clay soil, the porosity decreases by 38.5 %, 33.7 % and 29.2 %. When wind speed is 12 m/s, the mass loss of sandy soil, floury soil and clay soil cemented by bio-cementitious material are all less than 30 g/(m2·h). After three cycles of rainfall erosion of 2.5 mm/h, the mass loss are less than 25 g/(m2·h) and the compressive strength residual ratio are more than 98.0 %. Under 25 cycles of freeze-thaw, the mass loss ratio are less than 3.0 %.

Abstract

Motivation
Genomic analysis has become one of the major tools for disease outbreak investigations. However, existing computational frameworks for inference of transmission history from viral genomic data often do not consider intra-host diversity of pathogens and heavily rely on additional epidemiological data, such as sampling times and exposure intervals. This impedes genomic analysis of outbreaks of highly mutable viruses associated with chronic infections, such as human immunodeficiency virus and hepatitis C virus, whose transmissions are often carried out through minor intra-host variants, while the additional epidemiological information often is either unavailable or has a limited use.

Results
The proposed framework QUasispecies Evolution, Network-based Transmission INference (QUENTIN) addresses the above challenges by evolutionary analysis of intra-host viral populations sampled by deep sequencing and Bayesian inference using general properties of social networks relevant to infection dissemination. This method allows inference of transmission direction even without the supporting case-specific epidemiological information, identify transmission clusters and reconstruct transmission history. QUENTIN was validated on experimental and simulated data, and applied to investigate HCV transmission within a community of hosts with high-risk behavior. It is available at https://github.com/skumsp/QUENTIN.

Direct and Indirect Pathways From Social Support to Health?
Authors: Kim Seoyoun , Thomas Patricia A 
Published: June 2017

Abstract

Objectives
We aimed to investigate potential direct and indirect pathways linking social support and health, while considering mental health and chronic inflammation as inter-related outcomes. The study also contributes to the literature through testing potential bidirectional relationships between social support, mental health, and chronic inflammation.

Methods
This study uses Structural Equation Modeling and two waves of the National Social Life, Health, and Aging Project (NSHAP), including 1,124 community-living older adults aged 57–85 years at Wave 1 (2005).

Results
Analyses show that social support influenced mental health indirectly through better self-esteem. Moreover, social support was associated with lower levels of chronic inflammation but chronic inflammation did not influence social support.

Discussion
The growing number of older adults with an aging population urgently calls for a greater understanding of factors influencing their physical and mental health. The results of this study demonstrate the importance of social support in older adults’ health, while specifically focusing on understudied indirect pathways from social support to health.

Authors: Luo Ruibang , Schatz Michael C. , Salzberg Steven L. 
Published: June 2017

Abstract
16GT is a variant caller for Illumina whole-genome and whole-exome sequencing data. It uses a new 16-genotype probabilistic model to unify single nucleotide polymorphism and insertion and deletion calling in a single variant calling algorithm. In benchmark comparisons with 5 other widely used variant callers on a modern 36-core server, 16GT demonstrated improved sensitivity in calling single nucleotide polymorphisms, and it provided comparable sensitivity and accuracy for calling insertions and deletions as compared to the GATK HaplotypeCaller. 16GT is available at https://github.com/aquaskyline/16GT.
Massive quiescent galaxies at z &gt; 3 in the Millennium simulation populated by a semi-analytic galaxy formation model
Authors: Rong Yu , Jing Yingjie , Gao Liang , Guo Qi , Wang Jie , Sun Shuangpeng , Wang Lin , Pan Jun 
Published: June 2017

Abstract
We take advantage of the statistical power of the large-volume dark-matter-only Millennium simulation (MS), combined with a sophisticated semi-analytic galaxy formation model, to explore whether the recently reported z = 3.7 quiescent galaxy ZF-COSMOS-20115 (ZF) can be accommodated in current galaxy formation models. In our model, a population of quiescent galaxies with stellar masses and star formation rates comparable to those of ZF naturally emerges at redshifts z &lt; 4. There are two and five ZF analogues at the redshifts 3.86 and 3.58, respectively, in the MS volume. We demonstrate that, while the z &gt; 3.5 massive QGs are rare (about 2 per cent of the galaxies with the similar stellar masses), the existing AGN feedback model implemented in the semi-analytic galaxy formation model can successfully explain the formation of the high-redshift QGs as it does on their lower redshift counterparts.

Published: June 2017

Abstract

BACKGROUND
Image guidance based on magnetic resonance imaging (MRI) and/or ultrasound (US) is widely used to aid decision making in glioma surgery, but tumor delineation based on these 2 modalities does not always correspond.

OBJECTIVE
To analyze volumes of diffuse low-grade gliomas (LGGs) based on preoperative 3-D FLAIR MRIs compared to intraoperative 3-D US image recordings to quantitatively assess potential discrepancies between the 2 imaging modalities.

METHODS
Twenty-three patients with supratentorial WHO grade II gliomas undergoing primary surgery guided by neuronavigation based on preoperative FLAIR MRI and navigated 3-D US were included. Manual volume segmentation was performed twice in 3-D Slicer version 4.0.0 to assess intrarater variabilities and compare modalities with regard to tumor volume. Factors possibly related to correspondence between MRI and US were also explored.

RESULTS
In 20 out of 23 patients (87%), the LGG tumor volume segmented from intraoperative US data was smaller than the tumor volume segmented from the preoperative 3-D FLAIR MRI. The median difference between MRI and US volumes was 7.4 mL (range: −4.9-58.7 mL, P < .001) with US LGG volumes corresponding to a median of 74% (range: 42%-183%) of the MRI LGG volumes. However, there was considerable intraobserver variability for US volumes. The correspondence between MRI and US data was higher for astrocytomas (92%).

CONCLUSION
The tumor volumes of LGGs segmented from intraoperative US images were most often smaller than the tumor volumes segmented from preoperative MRIs. There was a much better match between the 2 modalities in astrocytomas.
Modern reirradiation for recurrent gliomas can safely delay tumor progression
Authors: Youland Ryan S , Lee John Y , Kreofsky Cole R , Brown Paul D , Uhm Joon H , Laack Nadia N 
Published: June 2017

Abstract

Background
Despite advances in modern therapy, high-grade gliomas continue to portend a dismal prognosis and nearly all patients will experience relapse. Unfortunately, salvage options remain limited. In this study, we assessed outcomes for patients with recurrent gliomas treated with reirradiation.

Methods
We retrospectively identified 48 glioma patients treated with reirradiation between 2013 and 2016. All had radiographic or pathologic evidence of recurrence. Prognostic factors were abstracted from the electronic medical record.

Results
Initial surgery included biopsy in 15, subtotal resection in 21, and gross total resection in 12. Initial chemotherapy included temozolomide (TMZ) in 31, TMZ+dasatinib in 7, TMZ+vorinostat in 3, and procarbazine, lomustine, and vincristine in 2. The median dose of primary radiotherapy was 60 Gy delivered in 30 fractions. Median overall survival (OS) and progression-free survival (PFS) from initial diagnosis were 3.2 and 1.7 years, respectively. A total of 36 patients failed salvage bevacizumab before reirradiation. Salvage surgery was performed before reirradiation in 21 patients. Median time to reirradiation was 1.7 years. Median follow-up was 13.7 months from reirradiation. Concurrent systemic therapy was given in 33 patients (bevacizumab in 27, TMZ in 8, and lomustine in 2). Median PFS and OS after reirradiation were 3.2 and 6.3 months, respectively. Radionecrosis occurred in 4 patients and no radionecrosis was seen in patients receiving concurrent bevacizumab with reirradiation (0% vs 19%, P = .03).

Conclusions
Reirradiation may result in delayed tumor progression with acceptable toxicity. Prospective trials are needed to determine the impact of reirradiation on tumor progression and quality of life.
Photometric studies for two contact binaries: V532 Monocerotis and GU Orionis
Authors: Yang Yuangui , Dai Haifeng , Yuan Huiyu , Zhang Xiliang , Zhang Liyun 
Published: June 2017

Abstract
We present photometry and spectroscopy data for V532 Mon and GU Ori, observed in 2011 and 2016. From the spectral observations, the spectral types are determined to be F5V for V532 Mon and G0V for GU Ori. With the 2015-version Wilson–Devinney program, the photometric solutions are simultaneously deduced from VR light curves (LCs). The intrinsic variability for V532 Mon is found by comparing LCs in 2004 and 2011, while the asymmetric LCs for GU Ori are modeled by a cool spot on the more massive component. The results imply that the two stars are A-type contact binaries. The mass ratios and fill-out factors are, respectively, q = 0.190(±0.006) and f = 43.7(±0.9)% for V532 Mon and q = 0.455(±0.020) and f = 26.9(±1.3)% for GU Ori. From the (O − C) curves, it is found that their orbital periods may be undergoing long-term variations. The rates of period change are dP/dt = −1.72(±0.05) × 10−7 d yr−1 for V532 Mon and dP/dt = +1.45(±0.01) × 10−7 d yr−1 for GU Ori. V532 Mon with a decreasing period will evolve into a deep-contact binary, while GU Ori with an increasing period may evolve into a broken-contact case.

Abstract
We report the discovery of a diffuse stellar cloud with an angular extent ≳30″, which we term “Sumo Puff”, in data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). While we do not have a redshift for this object, it is in close angular proximity to a post-merger galaxy at redshift z = 0.0431 and is projected within a few virial radii (assuming similar redshifts) of two other ∼L⋆ galaxies, which we use to bracket a potential redshift range of 0.0055 &lt; z &lt; 0.0431. The object’s light distribution is flat, as characterized by a low Sérsic index (n ∼ 0.3). It has a low central g-band surface brightness of ∼26.4 mag arcsec−2, large effective radius of ∼13″ (∼11 kpc at z = 0.0431 and ∼1.5 kpc at z = 0.0055), and an elongated morphology (b/a ∼ 0.4). Its red color (g − i ∼ 1) is consistent with a passively evolving stellar population and similar to the nearby post-merger galaxy, and we may see tidal material connecting Sumo Puff with this galaxy. We offer two possible interpretations for the nature of this object: (1) it is an extreme, galaxy-sized tidal feature associated with a recent merger event, or (2) it is a foreground dwarf galaxy with properties consistent with a quenched, disturbed, ultra-diffuse galaxy. We present a qualitative comparison with simulations that demonstrates the feasibility of forming a structure similar to this object in a merger event. Follow-up spectroscopy and/or deeper imaging to confirm the presence of the bridge of tidal material will be necessary to reveal the true nature of this object.
