AbstractUnderstanding the relative importance of dispersal limitation and environmental filtering processes in structuring the beta diversities of subtropical forests in human disturbed landscapes is still limited. Here we used taxonomic (TBD) and phylogenetic (PBD), including terminal PBD (PBDt) and basal PBD (PBDb), beta diversity indices to quantify the taxonomic and phylogenetic turnovers at different depths of evolutionary history in disturbed and undisturbed subtropical forests. Multiple linear regression model and distance-based redundancy analysis were used to disentangle the relative importance of environmental and spatial variables. Environmental variables were significantly correlated with TBD and PBDt metrics. Temperature and precipitation were major environmental drivers of beta diversity patterns, which explained 7–27% of the variance in TBD and PBDt, whereas the spatial variables independently explained less than 1% of the variation for all forests. The relative importance of environmental and spatial variables differed between disturbed and undisturbed forests (e.g., when Bray-Curtis was used as a beta diversity metric, environmental variable had a significant effect on beta diversity for disturbed forests but had no effect on undisturbed forests). We conclude that environmental filtering plays a more important role than geographical limitation and disturbance history in driving taxonomic and terminal phylogenetic beta diversity.

AbstractOrganic-inorganic perovskite materials, typically methylammonium lead trihalide (MAPbX3: MA = methylammonium; X = Br, I), are recently attract enormous attention for their distinguished photo-electronic properties. The control of morphology, composition and dispersability of MAPbX3 perovskite nanocrystals is crucial for the property tailoring and still a major challenge. Here we report the synthesis of colloidal MAPbBrxI3−x(0 ≤ x ≤ 3) nanocrystals at room temperature by using alkyl carboxylate as capping ligands. These nanocrystals exhibit continuously tunable UV-vis absorption and photoluminescence (PL) across the visible spectrum, which is attributed to the quantum confinement effect with certain stoichiometry. Their unique exciton recombination dynamics was investigated and discussed.
A high-throughput microfluidic approach for 1000-fold leukocyte reduction of platelet-rich plasma

Published: October 2016

AbstractLeukocyte reduction of donated blood products substantially reduces the risk of a number of transfusion-related complications. Current ‘leukoreduction’ filters operate by trapping leukocytes within specialized filtration material, while allowing desired blood components to pass through. However, the continuous release of inflammatory cytokines from the retained leukocytes, as well as the potential for platelet activation and clogging, are significant drawbacks of conventional ‘dead end’ filtration. To address these limitations, here we demonstrate our newly-developed ‘controlled incremental filtration’ (CIF) approach to perform high-throughput microfluidic removal of leukocytes from platelet-rich plasma (PRP) in a continuous flow regime. Leukocytes are separated from platelets within the PRP by progressively syphoning clarified PRP away from the concentrated leukocyte flowstream. Filtrate PRP collected from an optimally-designed CIF device typically showed a ~1000-fold (i.e. 99.9%) reduction in leukocyte concentration, while recovering >80% of the original platelets, at volumetric throughputs of ~1 mL/min. These results suggest that the CIF approach will enable users in many fields to now apply the advantages of microfluidic devices to particle separation, even for applications requiring macroscale flowrates.

AbstractHypermethylated cancer populations are hard to treat due to their enhanced chemo-resistance, characterized by aberrant methylated DNA subunits. Herein, we report on invoking response from such a cancer lineage to chemotherapy utilizing multifunctional copper telluride (Cu2−XTe) nanocubes (NCs) as photothermal and photodynamic agents, leading to significant anticancer activity. The NCs additionally possessed photoacoustic and X-ray contrast imaging abilities that could serve in image-guided therapeutic studies.
Evaluating the Impact of a Multistrategy Inference Intervention for Middle-Grade Struggling Readers
Authors: Barth Amy E. , Elleman Amy 
Published: October 2016

Purpose
We examined the effectiveness of a multistrategy inference intervention designed to increase inference making and reading comprehension for middle-grade struggling readers.

Method

A total of 66 middle-grade struggling readers were randomized to treatment (
n
= 33) and comparison (
n
= 33) conditions. Students in the treatment group received explicit instruction in 4 inference strategies (i.e., clarification using text clues; activating and using prior knowledge; understanding character perspectives and author's purpose; answering inferential questions). In addition, narrative and informational texts were carefully chosen and sequenced to build requisite background knowledge to form inferences. Intervention was delivered in small groups of 3 students for 10 days of instruction.

Results

One-way analysis of covariance models on outcome measures with the respective pretest scores as a covariate revealed significant gains on a proximal measure of Egyptian-content knowledge (
g
= 1.37) and on a standardized measure of reading comprehension—i.e., Wechsler Individual Achievement Test–Third Edition Reading Comprehension (
g
= 0.46).

Conclusion
The moderate effect on a standardized measure of reading comprehension provides preliminary evidence for the effectiveness of this multistrategy inference intervention in improving reading comprehension of middle-grade struggling readers.
Precise current sharing control for multi‐channel LED driver based on switch‐controlled capacitor
Authors: Liu Junfeng , Sun Weihua , Zeng Jun 
Published: October 2016

A switch‐controlled capacitor (SCC)‐based driver circuit is proposed for current sharing of multi‐channel light‐emitting diode (LED). The proposed circuit includes a transformer primary side and several secondary sides. Each secondary side as an independent unit includes an SCC module, a resonant inductor and an H‐bridge to power two‐channel LEDs. Two output channels within a capacitor unit achieve current sharing due to charging or discharging balance of SCC module. Since the current in each capacitor unit can be regulated independently, the proposed topology is accommodated with more units. The current sharing among different capacitor units can be realised by the adjustment of SCC module; therefore, the dimming also can be accomplished for multi‐channel LEDs. The operating cycles of SCC module, the working mode and simplified equivalent circuit are analysed in detail. The relations of LED current versus the equivalent capacitance are examined. The performance is evaluated by four‐channel prototype with input voltage of 48 V and rated power of 20 W. The output current is regulated from 180 to 350 mA per LED channel. The experimental results further prove that the proposed topology can effectively achieve current sharing of two LED channels, current sharing of four‐channel LED and independent dimming.

Published: October 2016

AbstractAirport security measures continue to be updated with the incorporation of the new body scanners and automatic target recognition software. The purpose of this study was analyze the incidence of: (1) triggering the security alarm; (2) extra security searches; (3) perceived inconvenience; and (4) presence of other surgical hardware in those who underwent total knee arthroplasty (TKA) and passed through airport security. A questionnaire was given to 125 consecutive patients with a TKA. Those who passed through airport security after January 2014 were considered for inclusion. A questionnaire was administered that addressed the number of encounters with airport security, metal detector activation, additional screening procedures, and perceived inconvenience. Out of the 125 patients, 53 met inclusion criteria. Out of the 53 patients, 20 (38%) reported that their prosthesis triggered a metal detector. Out of the 20 patients, 8 (40%) who reported triggering of metal detectors also reported the presence of surgical hardware elsewhere in the body. Eighteen of the 53 patients (34%) believed having a TKA was inconvenient for airplane travel. Compared with the historical cohort, alarms were triggered in 70 of 97 patients (p = 0.0001) and 50 of 97 reported inconvenience when traveling (n = 50 of 97 patients; p = 0.04). The incidences of those who underwent TKA triggering alarms and perceiving inconvenience when passing through airport security have decreased from previously published studies. This is most likely due to the recent updates and modifications to screening. As these security measures are modified and implant designs continue to evolve, this is an area of investigation that should continue.
Quantum-mechanical twin paradox
Authors: Franson J D 
Published: October 2016

Abstract
In the twin paradox of special relativity, an observer that travels along an accelerated trajectory at a high velocity will experience a smaller amount of elapsed time than an observer that remains at rest. This illustrates the fact that time is relative unlike the situation in classical physics where time is absolute. In a recent paper, Bushev et al (2016 New J. Phys.

18 093050) showed that the twin paradox can also be demonstrated using a single electron that functions as a quantum-mechanical clock. The wave function of the electron can travel along two different paths simultaneously, which allows a measurement of the difference in proper times along the two trajectories using a single particle. Quantum interference effects show that time cannot be thought of as a classical parameter even when associated with a single clock or observer.
Topologically protected loop flows in high voltage AC power grids

Published: October 2016

Abstract
Geographical features such as mountain ranges or big lakes and inland seas often result in large closed loops in high voltage AC power grids. Sizable circulating power flows have been recorded around such loops, which take up transmission line capacity and dissipate but do not deliver electric power. Power flows in high voltage AC transmission grids are dominantly governed by voltage angle differences between connected buses, much in the same way as Josephson currents depend on phase differences between tunnel-coupled superconductors. From this previously overlooked similarity we argue here that circulating power flows in AC power grids are analogous to supercurrents flowing in superconducting rings and in rings of Josephson junctions. We investigate how circulating power flows can be created and how they behave in the presence of ohmic dissipation. We show how changing operating conditions may generate them, how significantly more power is ohmically dissipated in their presence and how they are topologically protected, even in the presence of dissipation, so that they persist when operating conditions are returned to their original values. We identify three mechanisms for creating circulating power flows, (i) by loss of stability of the equilibrium state carrying no circulating loop flow, (ii) by tripping of a line traversing a large loop in the network and (iii) by reclosing a loop that tripped or was open earlier. Because voltages are uniquely defined, circulating power flows can take on only discrete values, much in the same way as circulation around vortices is quantized in superfluids.
Impacts of Federal Crop Insurance on Land Use and Environmental Quality
Authors: Claassen Roger , Langpap Christian , Wu JunJie 
Published: October 2016

AbstractThis article integrates economic and biophysical models to assess how federal crop revenue insurance programs affect land use, cropping systems, and environmental quality in the U.S. Corn Belt region. The empirical framework includes econometric models that predict land conversion and crop choices at the parcel level based on expectation and variance of crop revenues, land quality, climate conditions, and physical characteristics at each site. The predictions are then combined with site‐specific environmental production functions to determine the effect of revenue insurance on nitrate runoff and leaching, soil water and wind erosion, and carbon sequestration. Results suggest that federal crop insurance has, on average, a small effect on conversions of non‐cropland to cropland, and somewhat more significant impacts on crop choice and crop rotation. These changes in cropping systems have, on average, small impacts on agricultural pollution.
Suzaku and Chandra observations of CIZA J1700.8−3144, a cluster of galaxies in the Zone of Avoidance

Abstract
We present the Chandra and Suzaku observations of 1RXS J170047.8−314442, located towards the Galactic bulge, to reveal a wide-band (0.3–10 keV) X-ray morphology and spectrum of this source. With the Chandra observation, no point source was found at the position of 1RXS J170047.8−314442. Instead, we revealed the presence of diffuse X-ray emission, via the wide-band X-ray image obtained from the Suzaku XIS. Although the X-ray emission had a nearly circular shape with a spatial extent of ∼3${^{\prime}_{.}}$5, the surface brightness profile was not axisymmetric; a bright spot-like emission was found at ∼ 1΄ away in the northwestern direction from the center. The radial profile of the surface brightness, except for this spot-like emission, was reproduced with a single β-model; β and the core radius were found to be 1.02 and 1${^{\prime}_{.}}$51, respectively. The X-ray spectrum of the diffuse emission showed an emission line at ∼6 keV, indicating an origin of a thermal plasma. The spectrum was well explained with an absorbed, optically-thin thermal plasma model with a temperature of 6.2 keV and a redshift parameter of z = 0.14 ± 0.01. Hence, the X-ray emission was considered to arise from the hot gas associated with a cluster of galaxies. Our spectroscopic result confirmed the optical identification of 1RXS J170047.8−314442 by Kocevski et al. (2007, ApJ, 662, 224): CIZA J1700.8−3144, a member of the cluster catalogue in the Zone of Avoidance. The estimated bolometric X-ray luminosity of 5.9 × 1044 erg s−1 was among the lowest with this temperature, suggesting that this cluster is far from relaxed.
Primary Cutaneous Mammary Analog Secretory Carcinoma With ETV6-NTRK3 Translocation

Published: October 2016

Abstract:
Mammary analog secretory carcinoma (MASC) is a recently described tumor of the salivary glands named for its morphological and molecular similarity to secretory carcinoma of the breast. Many primary carcinomas arising from the adnexal glands also share similar morphology to those arising from the breast. Brandt et al first described primary cutaneous MASC in 2009 and since then only 2 other cases have been reported. Herein, we describe a long-standing mass on the arm of an otherwise healthy 40-year-old female. Histologic examination revealed a circumscribed but unencapsulated, nodular tumor composed of bland epithelial cells arranged in solid and microcystic growth patterns. The cells showed vacuolated cytoplasm and round to oval nuclei with vesicular chromatin. Intraluminal homogenous eosinophilic secretions were present. Mitotic figures were not identified. The tumor cells stained positive for CK8/18, CK7, and S100 but were negative for other markers performed, including estrogen receptor, progesterone receptor, HER2/neu, paired box 8 (PAX8), and thyroid transcription factor 1 (TTF1). As the patient clinically had no other masses or known carcinomas, a diagnosis of primary cutaneous MASC was rendered. The ETV6-NTRK3 fusion transcript was subsequently detected by reverse transcriptase polymerase chain reaction amplification, further supporting the diagnosis. We present this case to review the histologic features of MASC and highlight the importance of recognizing this lesion not only as a possible cutaneous metastasis but also as a primary cutaneous tumor.

Published: October 2016

Purpose:To analyze the incidence, risk factors, and time course of intraocular pressure elevation after intravitreal dexamethasone implant (Ozurdex).Methods:The medical charts of 421 consecutive eyes (361 patients) receiving one or more Ozurdex implant between October 2010 and February 2015 were reviewed retrospectively. Ocular hypertension was defined as intraocular pressure of at least 25 mmHg or an increase of at least 10 mmHg from baseline. The main indications for treatment were retinal vein occlusion (34%), diabetic macular edema (30%), postsurgical macular edema (17%), uveitis (14%), and other etiologies (5%).Results:Among 1,000 intravitreal injections, ocular hypertension was recorded for 28.5% of injected eyes over a mean follow-up period of 16.8 months (3–55). Intraocular pressure-lowering medication was required for 31% of eyes. Only three eyes with preexisting glaucoma required filtering surgery to manage postinjection intraocular pressure elevation. Early retreatment between the third and fourth month does not increase the risk of intraocular pressure elevation. Younger age, male sex, Type 1 diabetes, preexisting glaucoma treated with dual or triple therapy, and a history of retinal vein occlusion or uveitis were significant risk factors for ocular hypertension after dexamethasone implant injection (P< 0.05 for all the above).Conclusion:Episodes of ocular hypertension after Ozurdex implant were generally transient and successfully managed with topical treatment. An analysis of the risk factors may help to determine the risk–benefit ratio for individual patients treated with dexamethasone implants.

SummarySexual dimorphism manifests in many diseases and may drive sex-specific therapeutic responses. To understand the molecular basis of sexual dimorphism, we conducted a comprehensive assessment of gene expression and regulatory network modeling in 31 tissues using 8716 human transcriptomes from GTEx. We observed sexually dimorphic patterns of gene expression involving as many as 60% of autosomal genes, depending on the tissue. Interestingly, sex hormone receptors do not exhibit sexually dimorphic expression in most tissues; however, differential network targeting by hormone receptors and other transcription factors (TFs) captures their downstream sexually dimorphic gene expression. Furthermore, differential network wiring was found extensively in several tissues, particularly in brain, in which not all regions exhibit strong differential expression. This systems-based analysis provides a new perspective on the drivers of sexual dimorphism, one in which a repertoire of TFs plays important roles in sex-specific rewiring of gene regulatory networks.HighlightsSexual dimorphism manifests in both gene expression and gene regulatory networksSubstantial sexual dimorphism in regulatory networks was found in several tissuesMany differentially regulated genes are not differentially expressedSex hormone receptors do not exhibit sexually dimorphic expression in most tissues
How non-consumption goals (elicited by competitive setting or social risk) and self-confidence influence the importance of trivial attributes in product evaluation
Authors: Xiao Na 
Published: October 2016

Purpose
This research aims to provide new empirical evidence, showing that trivial attributes can exert a significant impact on product evaluation when they help to fulfill non-consumption goals (goal that goes beyond functional benefits).

Design/methodology/approach
The research presents two experimental studies that investigate the role of trivial product attributes in various non-consumption contexts.

Findings
Trivial attributes can have a significant impact on product evaluation when they help to fulfill non-consumption goals. First, in the non-competitive versus competitive choice settings, a trivial attribute becomes more important when it helps to make a choice (i.e. a non-consumption goal). Second, in the low versus high social risk settings, a trivial attribute becomes more important when it helps to reduce a social risk (i.e. a non-consumption goal). In addition, self-confidence is a moderator, which regulates consumers’ ability to rely on trivial attributes in making product choices.

Research limitations/implications
The social risk manipulations (high vs low) were operationalized by manipulating the impression motive related to social risk. The more important a goal is, the more risk consumers feel in decision making (Lazarus, 1991). Therefore, risk is a proxy of the goal strength or goal relevance. Future research is needed to examine goal strength’s sole influence on the perception of the trivial attribute.

Practical implications
From managerial perspective, trivial attributes can help companies to improve their sales. For example, a way to increase an attribute’s importance is to put the product in a competitive setting. Increasing a social risk further increases the influence of trivial attributes. When less confident consumers perceive the social risk is high, they prefer a brand with a trivial attribute. For consumers, the findings also suggest that consumers should not be tempted to consider trivial attributes in their purchase decisions. Reconsidering attributes and increasing self-confidence could help maintain focus on non-trivial attributes.

Originality/value
The study makes several contributions to theory and practice. This is the first study to systematically propose a framework of how trivial attributes’ role in product evaluation and choice change based on goals. The paper clarifies confusions about the definitions of trivial attributes and reconciles contradictory findings in literature. A trivial attribute can be instrumental in evaluation and choice when it helps to achieve a non-consumption goal. It is also the first study to introduce social risks into trivial attributes research in choices. The findings provide empirical evidence that social risks and self-confidence together drive consumers to prefer for trivial attribute.
