Sharp roll‐off lowpass filter using interdigital DGS slot
Authors: Liu Shuai , Xu Jun , Xu Zhitao 
Published: August 2015

A novel lowpass filter (LPF) with a sharp roll‐off and a wide stopband is presented. The proposed LPF is based on a dual‐plane structure with an interdigital shape defected ground structure (DGS). The DGS exhibits a sharp roll‐off and three transmission zeros. By tuning the length of the fingers, the resonant frequency can be easily changed. Based on the proposed DGS, a LPF has been designed, fabricated and measured. The transition band is from 3.11 (fc) to 3.23 GHz with −3.02 and −22.5 dB, respectively. The stopband with rejection better than 25 dB can be extended to 3.4 fc.

Authors: Xu Li‐Jie , Zhang Gang , Tang Yi‐Ming , Bo Ya‐Ming 
Published: August 2015

A compact dual‐mode dual‐band bandpass filter (BPF) for WLAN applications is presented. On the basis of a primary passband formed by a ring resonator, a second passband is introduced by taking advantage of its tightly coupled input and output structures. Therefore, a dual‐band performance is achieved without increasing the overall circuit size. Shorting vias and spurlines are adopted separately to realise the dual‐mode excitation of each passband. Finally, a compact dual‐mode BPF centred at 2.4 and 5.2 GHz is designed and fabricated, along with four transmission zeros, leading to sharp skirts and a wide stopband. Experimental results reveal good agreement with simulation results.

Published: August 2015

A small footprint diode laser array of 24 individually addressable distributed Bragg reflector lasers is presented. Third‐order gratings etched into the surface of an AlGaAs vertical waveguide structure act as Bragg reflectors. The ridge waveguides have an 87 µm‐wide spacing and the emission wavelengths are spread on a 0.5 nm‐wide grid around a centre wavelength of 905 nm. All 24 lasers on the array emit single mode with side mode suppression ratios > 50 dB and output powers >17 mW at 40 mA pump current.

Published: August 2015

The potential of highly flexible and conductive graphene laminate is extended to the application of electromagnetic interference shielding. Graphene nanoflake‐based conductive ink is printed on paper, and compressed to form a graphene laminate with a conductivity of 0.43 × 105 S/m. The shielding effectiveness is experimentally measured to be above 32 dB between 12 and 18 GHz, even though the thickness of the graphene laminate is only 7.7 µm. It is demonstrated that graphene has great potential in offering lightweight, low‐cost, flexible and environmentally‐friendly shielding materials.

Authors: Caudron Mathieu , Rolland Benjamin , Deheul Sylvie , Geoffroy Pierre Alexis , Thomas Pierre , Amad Ali 
Published: August 2015

Background Catatonia is a severe motor syndrome found in approximately 10% of all acute psychiatric hospital admissions. It can occur in various psychiatric diseases. The authors report the first case report of catatonia during cannabis withdrawal. Case Presentation: Mr. A, a 32-year-old man, reported to have smoked approximately 20 g of cannabis daily since the age of 11. Mr. A was incarcerated and was reported 3 weeks later to the medical department for having completely ceased talking and eating. At admission in the authors’ department, the patient presented with classical catatonia symptoms (Bush-Francis Catatonia Rating Scale [BFCRS] score = 39/69). All laboratory results and brain magnetic resonance imaging (MRI) were normal. Six weeks after his admission and treatments by lorazepam and memantine, his BFCRS score was 0/69. Discussion: This single case study highlights the previously underreported emergence of physical and motor symptoms following cannabis withdrawal. Pathophysiological aspects of abrupt cannabis cessation contributing to γ-aminobutyric acid (GABA)/glutamate balance dysregulation and to catatonia are discussed.
Heart Rate Recovery is an Important Predictor of Outcomes in Patients with Connective Tissue Disease–Associated Pulmonary Hypertension

Published: August 2015

Reduced heart rate recovery (HRR) after exercise is associated with increased mortality in cardiac and pulmonary diseases. We sought to evaluate the association between HRR after the 6‐minute walk test (6MWT) and outcomes in patients with connective tissue disease–associated pulmonary hypertension (CTD‐PH). Data were obtained by review of the medical records. HRR was defined as the difference in heart rate at the end of the 6MWT and after 1 minute (HRR1), 2 minutes (HRR2), and 3 minutes (HRR3) of rest. All patients with pulmonary hypertension and a diagnosis of systemic sclerosis, systemic lupus erythematosus, or mixed connective tissue disease who underwent the 6MWT between August 1, 2009, and October 30, 2011, were included (n = 66). By Kaplan‐Meier analysis, HRR1, HRR2, and HRR3 at different cutoff points were all good predictors, with HRR1 of <16 being the best predictor of time to clinical worsening (log‐rank P < 0.0001), hospitalization (log‐rank P = 0.0001), and survival (log‐rank P < 0.003). By proportional hazards regression, patients with HRR1 of <16 were at increased risk of clinical worsening (hazard ratio [HR]: 6.4 [95% confidence interval (CI): 2.6–19.2]; P < 0.0001], hospitalization (HR: 6.6 [95% CI: 2.4–23]; P < 0.0001), and death (HR: 4.5 [95% CI: 1.6–15.7]; P = 0.003). Patients in the highest tercile (HRR1 of ≥19) were unlikely to have a clinical worsening event (HR: 0.1 [95% CI: 0.04–0.5]; P = 0.001], to be hospitalized (HR: 0.1 [95% CI: 0.02–0.5]; P = 0.001), or to die (HR: 0.3 [95% CI: 0.07–0.9]; P = 0.04]. In conclusion, in patients with CTD‐PH, abnormal HRR1 (defined as HRR1 of <16) after the 6MWT is a strong predictor of clinical worsening, time to clinical worsening, survival, and hospitalization.

: Jean-Luc Nancy's ‘Sonotropism’
Authors: Hickmott Sarah 
Published: August 2015

Abstract

This article offers a critical, feminist, and interdisciplinary account of the question of listening in Jean-Luc Nancy's 2002 text,
À l'écoute
. Nancy's text is at once an auditory counterpart to his larger philosophical project; an articulation of the specifically sonorous subject; and a more expressly musicological contribution to his other work on the literary and visual arts. While Nancy's — among others' — attempts at steering philosophy away from or beyond a visual bias proliferate, considerably less commentary has been devoted to the way in which inherited ideas about aesthetic ‘objects’ — in this case music— already inhabit certain conceptions of the senses. By paying close attention to the characterization and inclusion of music in the
corps sonore
, and by tracing the genealogies of Nancy's thought on music (and sound), this article will finally offer a rereading of Nancy's oto-iconographical reading of Titian's
Venus and Cupid with an Organist
; one that highlights the ethical and political dimensions of Nancy's position. I shall argue that problematic and preconceived notions about the supposed nature of music abound in Nancy's philosophy of listening, revealing a metaphysical (sono)tropism that is all too familiar.
Escape conditions of radiative-driven strati from luminous accretion disks
Authors: Nakai Takuya , Fukue Jun 
Published: August 2015

Abstract
We examine the dynamical motion and escape conditions of continuum-driven strati (flat cloud) with finite optical depth from luminous accretion disks around a black hole. We adopt the near-disk approximation, and treat the problem in the framework of special relativity, where the radiation drag force as well as the radiation pressure are included. We find that the optically thin strati are easy to accelerate, compared with the particles, and the escape condition of the stratus is reduced. That is, when the disk luminosity is around the Eddington luminosity, the optically thin strati can escape from the inner disk (≲ 20 rg; rg being the Schwarzschild radius). When the disk luminosity is about half the Eddington luminosity, it can escape at around 5 rg. This is due to the translucent effect. In addition, the trajectories of the strati are not vertical, but a funnel-like shape due to the centrifugal force. Stratus outflow could easily blow out from usual accretion disks with sub-Eddington luminosities, and this may explain outflows observed in broad absorption line quasars and ultra-fast outflow objects.
Avoiding accuracy-limiting pitfalls in the study of protein-ligand interactions with isothermal titration calorimetry
Authors: Boyce Sarah E. , Tellinghuisen Joel , Chodera John D. 
Published: August 2015

AbstractIsothermal titration calorimetry (ITC) can yield precise (3%) estimates of the thermodynamic parameters describing biomolecular association (affinity, enthalpy, and entropy), making it an indispensable tool for biochemistry and drug discovery. Surprisingly, interlaboratory comparisons suggest that errors of ∽ 20% are common and widely underreported. Here, we show how to reduce precision- and accuracy-limiting errors while obtaining good estimates and minimizing material and time consumed by an experiment. We provide a simple spreadsheet that allows practitioners to identify precision-limiting operations during protocol design, track precision during the experiment, and propagate error to yield realistic final uncertainties.
Species Tree Estimation from Genome-wide Data with Guenomu
Authors: Oliveira Martins Leonardo de , Posada David 
Published: August 2015

SummaryThe history of particular genes and that of the species that carry them can be different due to different reasons. In particular, gene trees and species trees can truly differ due to well-known evolutionary processes like gene duplication and loss, lateral gene transfer or incomplete lineage sorting. Different species tree reconstruction methods have been developed to take this incongruence into account, which can be divided grossly into supertree and supermatrix approaches. Here, we introduce a new Bayesian hierarchical model that we have recently developed and implemented in the program Guenomu, that considers multiple sources of gene tree/species tree disagreement. Guenomu takes as input the posterior distributions of unrooted gene tree topologies for multiple gene families, in order to estimate the posterior distribution of rooted species tree topologies.
D3M: Detection of differential distributions of methylation levels
Authors: Matsui Yusuke , Mizuta Masahiro , Miyano Satoru , Shimamura Teppei 
Published: August 2015

ABSTRACTMotivation:DNA methylation is an important epigenetic modification related to a variety of diseases including cancers. We focus on the methylation data from Illumina’s Infinium HumanMethylation450 BeadChip. One of the key issues of methylation analysis is to detect the differential methylation sites between case and control groups. Previous approaches describe data with simple summary statistics and kernel function, and then use statistical tests to determine the difference. However, a summary statistics-based approach cannot capture complicated underlying structure, and a kernel functions-based approach lacks interpretability of results.Results:We propose a novel method D3M, for detection of differential distribution of methylation, based on distribution-valued data. Our method can detect high-order moments, such as shapes of underlying distributions in methylation profiles, based on the Wasserstein metric. We test the significance of the difference between case and control groups and provide an interpretable summary of the results. The simulation results show that the proposed method achieves promising accuracy and shows favorable results compared with previous methods. Glioblastoma multiforme and lower grade glioma data from The Cancer Genome Atlas show that our method supports recent biological advances and suggests new insights.Availability:R implemented code is freely available fromhttps://github.com/ymatts/D3M/https://cran.r-project.org/package=D3M.Contact:ymatsui@med.nagoya-u.ac.jp

AbstractTransposons are mobile genetic elements that are found in nearly all organisms, including humans. Mobilization of DNA transposons by transposase enzymes can cause genomic rearrangements, but our knowledge of human genes derived from transposases is limited. Here, we find that the protein encoded by humanPGBD5, the most evolutionarily conserved transposable element-derived gene in chordates, can induce stereotypical cut-and-paste DNA transposition in human cells. Genomic integration activity of PGBD5 requires distinct aspartic acid residues in its transposase domain, and specific DNA sequences with inverted terminal repeats with similarity topiggyBactransposons. DNA transposition catalyzed by PGBD5 in human cells occurs genome-wide, with precise transposon excision and preference for insertion at TTAA sites. The apparent conservation of DNA transposition activity by PGBD5 raises the possibility that genomic remodeling may contribute to its biological function.
The impact of partitioning on phylogenomic accuracy
Authors: Darriba Diego , Posada David 
Published: August 2015

AbstractSeveral strategies have been proposed to assign substitution models in phylogenomic datasets, or partitioning. The accuracy of these methods, and most importantly, their impact on phylogenetic estimation has not been thoroughly assessed using computer simulations. We simulated multiple partitioning scenarios to benchmark twoa prioripartitioning schemes (one model for the whole alignment, one model for each data block), and two statistical approaches (hierarchical clustering and greedy) implemented in PartitionFinder and in our new program, PartitionTest. Most methods were able to identify optimal partitioning schemes closely related to the true one. Greedy algorithms identified the true partitioning scheme more frequently than the clustering algorithms, but selected slightly less accurate partitioning schemes and tended to underestimate the number of partitions. PartitionTest was several times faster than PartitionFinder, with equal or better accuracy. Importantly, maximum likelihood phylogenetic inference was very robust to the partitioning scheme. Best-fit partitioning schemes resulted in optimal phylogenetic performance, without appreciable differences compared to the use of the true partitioning scheme. However, accurate trees were also obtained by a “simple” strategy consisting of assigning independent GTR+G models to each data block. On the contrary, leaving the data unpartitioned always diminished the quality of the trees inferred, to a greater or lesser extent depending on the simulated scenario. The analysis of empirical data confirmed these trends, although suggesting a stronger influence of the partitioning scheme. Overall, our results suggests that statistical partitioning, but also thea prioriassignment of independent GTR+G models, maximize phylogenomic performance.
Trait Evolution on Phylogenetic Networks
Authors: Jhwueng Dwueng-Chwuan , O’Meara Brian C. 
Published: August 2015

AbstractSpecies may evolve on a reticulate network due to hybridization or other gene flow rather than on a strictly bifurcating tree, but comparative methods to deal with trait evolution on a network are lacking. We create such a method, which uses a Brownian motion model. Our method seeks to separately or jointly detect a bias in trait value coming from hybridization (β) and a burst of variation at the time of hybridization (vH) associated with the hybridization event, as well as traditional Brownian motion parameters of ancestral state (μ) and rate of evolution (σ2) of Brownian motion, as well as measurement error of the tips (SE). We test the method with extensive simulations. We also apply the model to two empirical examples, cichlid body size andNicotianadrought tolerance, and find substantial measurement error and a hint that hybrids have greater drought tolerance in the latter case. The new methods are available in CRAN R packageBMhyd.
Disentangling sources of selection on exonic transcriptional enhancers
Authors: Agoglia Rachel M. , Fraser Hunter B. 
Published: August 2015

AbstractIn addition to coding for proteins, exons can also impact transcription by encoding regulatory elements such as enhancers. It has been debated whether such features confer heightened selective constraint, or evolve neutrally. We have addressed this question by developing a new approach to disentangle the sources of selection acting on exonic enhancers, in which we model the evolutionary rates of every possible substitution as a function of their effects on both protein sequence and enhancer activity. In three exonic enhancers, we found no significant association between evolutionary rates and effects on enhancer activity. This suggests that despite having biochemical activity, these exonic enhancers have no detectable selective constraint, and thus are unlikely to play a major role in protein evolution.
Australian government budget balance numbers
Authors: Wines Graeme , Scarborough Helen 
Published: August 2015

Purpose– The purpose of this paper is to analyse the nature and comparability of budget balance (surplus/deficit) numbers headlined by the Australian Commonwealth Government and the governments of the six Australian States and the two Australian Territories. It does this in the context of the transition to Australian accounting standard AASB 1049 Whole of Government and General Government Sector Financial Reporting.Design/methodology/approach– A case study research method is adopted, based on a content/documentary analysis of the headline budget balance numbers in the general government sector budget statements of each of the nine governments for the eight financial years from 2004-2005 to 2011-2012.Findings– Findings indicate some variation in the measurement bases adopted and a number of departures from the measurement bases prescribed in the reporting frameworks, including AASB 1049. Findings also reveal that none of the nine governments have headlined a full accrual based budget balance number since the implementation of AASB 1049 in 2008.Research limitations/implications– While the study focuses on the Australian general government sector environment, it has significant implications in highlighting the ambiguity in the government budget balance numbers presented and the monitoring and information asymmetry problems that can arise. Research findings have wider relevance internationally in highlighting issues arising with the public sector adoption of accrual accounting.Practical implications– The paper highlights the manner in which governments have been selective in the manner in which they present important budget aggregates. This has important practical and social implications, as the budget balance number is one of the most important measures used to evaluate a government’s fiscal management and responsibility.Originality/value– The paper represents the first detailed examination of aspects of the effect of the transition to AASB 1049.
The effect of financial crisis on auditor conservatism: US evidence
Authors: Beams Joseph , Yan Yun-Chia 
Published: August 2015

Purpose
– This paper aims to examine the effect that the recent financial crisis had on auditor conservatism in the form of increased going-concern opinions.

Design/methodology/approach
– This study uses a sample of US’ distressed firms from 2005 to 2011 to test the change in going-concern opinions issued. This paper uses a logistic regression model to control for other predictors of going-concern opinions to determine when the financial crisis led to an increase in auditor conservatism.

Findings
– The authors find that auditors became more conservative in the form of issuing higher levels of going-concern opinions even after controlling for other predictors of going-concern opinions. This increased conservatism was present in both Big 4 and non-Big 4 accounting firms. The increased conservatism quickly returned to normal levels when the financial crisis eased.

Originality/value
– These findings add to the literature on the effects of environmental changes on audit opinions. Additionally, this study finds a difference in the timing of the reaction by large and small accounting firms, but, overall, it finds consistency in that both increased conservatism during the crisis and quickly returned to normal afterward.
Embodied prejudices: a study on diversity and practices
Authors: Figueiredo Marina Dantas de 
Published: August 2015

Purpose
– The purpose of this paper is to analyze organizational diversity with a focus on the concept of socially sustained practices, grounding the analyses in a practice-based approach.

Design/methodology/approach
– Based on data from ethnographic research, the author seeks to explain how the body and embodied marks that indicate an unequal distribution of power in society interfere with access to knowledge and in the organization of work.

Findings
– Data analyses suggest that embodied prejudices affect the division of labor and access to knowledge in organizational settings, contributing to perpetuating cultural and historical structures of domination that spark conscious attempts to manage race and gender diversity.

Originality/value
– Little research has investigated diversity from a practice-based standpoint. The originality of this paper is in its adoption of a phenomenological perspective to explain the experience of diversity as an ongoing bodily and embodied process.
Understanding context in diversity management: a multi-level analysis
Authors: Pringle Judith K. , Ryan Irene 
Published: August 2015

Purpose– The purpose of this paper is to operationalize context in diversity management research.Design/methodology/approach– A case analysis provides an example of the influences of context at macro, meso and micro levels. Country context (macro) and professional and organization contexts (meso) are analysed in relation to the micro individual experiences of gender and indigeneity at work.Findings– Tensions and inconsistencies at macro and meso levels impact on diversity management at a micro level. The authors demonstrate how power and context are intertwined in the biopolitical positioning of subjects in terms of gender and indigeneity. The contested legacy of indigenous-colonial relations and societal gender dynamics are “played out” in a case from the accounting profession.Research limitations/implications– Within critical diversity studies context and power are linked in a reciprocal relationship; analysis of both is mandatory to strengthen theory and practice. The multi-level analytical framework provides a useful tool to understand advances and lack of progress for diversity groups within specific organizations.Originality/value– While many diversity scholars agree that the analysis of context is important, hitherto its application has been vague. The authors conduct a multi-level analysis of context, connecting the power dynamics between the levels. The authors draw out implications within one profession in a specific country socio-politics. Multi-level analyses of context and power have the potential to enhance the theory and practice of diversity management.
