Printed cross‐dipole antenna with slow‐wave structure for highly efficient and directive WLAN applications
Authors: Park S.‐B. , Eom S.‐Y. 
Published: May 2017

A study of printed cross‐dipole antenna with slow‐wave parasitic elements used to achieve high efficiency and directivity is presented. The proposed antenna is designed to operate at WLAN channels (5.15–5.85 GHz), and can produce dual‐orthogonal polarisation through a crossed structure. The printed slow‐wave elements play a role that concentrates on travelling wave and delays propagation of electromagnetic wave. Measurement results of this antenna show that it has high gain, low side‐lobe level and wide bandwidth. This proposed design has advantages in terms of manufacturing the antenna easily and optimising the radiation characteristics.

Windowing UWB microwave, mm‐wave multi‐port S‐parameter measurements using open‐ended excess electrical length
Authors: Askari Gholamreza , Kamarei Mahmoud 
Published: May 2017

Multi‐port measurements are a big challenge in circuits' verification, especially when the frequency increases. This study presents a new technique for measuring S‐parameters of multi‐port ultra‐wideband (UWB) microwave and mm‐wave circuits. The concepts are based on direct or indirect applying modulated UWB impulse radio in desired bandwidth to the one port of the modified multi‐port circuit and gathering the reflected signal in the same port and the output signal in the second port in time domain, and the other ports are left opened with a special designed added electrical length. Then by applying intelligent windowing in time domain to the gathering data, and using fast Fourier transform, the desired S‐parameters are extracted. Validation of this technique is verified by design and fabrication of a three‐port UWB Wilkinson power divider in 22–30 GHz. The simulation and measurement results of the reflection and transmission S‐parameters by using this new technique are very close to those are extracted with the conventional vector network analysers S‐parameters measurements and show the ability and the accuracy of this technique.
How Are Neonatology Fellows Trained for Antenatal Periviability Counseling?
Authors: Williams David , Carter Brian , Feltman Dalia 
Published: May 2017

Background Studies have shown rates of life-sustaining treatments for periviable newborns vary by center, centers' differing periviability approaches affect trainees' views, and formal communication training for neonatology fellows is uncommon. Parents of imperiled newborns report unmet emotional and spiritual needs. This study sought to understand how fellows learn to support parents and their periviable newborns through exposure to institutional clinical approaches and by formal curriculum.
Methods All the U.S. neonatology fellowship program directors were invited to complete an online anonymous survey. Data were analyzed with descriptive statistics.
Results In this study, 56 of 98 directors (57%) responded. Training centers differed in delivery room options offered and recommended for periviable newborns. Providing parents written information and neonatology and obstetrics co-counseling were uncommon. Directors reported weaknesses in training fellows to support parents' spiritual and emotional needs, and < 50% reported formal policies for involving social workers or chaplain. Fellows learned periviability counseling in 95% programs by observing attending physicians; however, only 54% directors reported typical joint daytime counseling with fellows and attending physicians.
Conclusion Training programs exposed fellows to different periviability care approaches, identified weaknesses in teaching support provision for parents' needs, and appeared to miss opportunities for clinical modeling of counseling and comfort care provision.

ZusammenfassungVersorgungsforscher_innen beschäftigen sich mit den Akteur_innen, Strukturen und Auswirkungen von Gesundheitsversorgung. Dies umfasst z. B. die Frage, wie soziale Faktoren, Finanzierungssysteme, Organisationsstrukturen, Technologien und persönliche Verhaltensweisen sich auf die Akteure und Ergebnisse des Versorgungsprozesses auswirken. Im Zuge dessen finden auch qualitative Methoden, die das Handeln von Menschen unter ihren jeweiligen Lebensbedingungen und nicht im klinisch-experimentellen Kontext betrachten, Anwendung. Gruppenverfahren gehören dabei zu den grundlegenden Erhebungszugängen der qualitativen Versorgungsforschung. Um die Potenziale von Gruppenverfahren (Gruppendiskussion bzw. Fokusgruppen) innerhalb der Versorgungsforschung sichtbar zu machen, sollen diese im Rahmen von 2 Artikeln in ihren Facetten und bezogen auf die Anwendung in der Versorgungsforschung dargestellt werden. Wir möchten mit diesem ersten Artikel Versorgungsforscher_innen dazu anregen, über bestimmte Fragen zu Wahl und Varianten der Methode sowie zur Planung von Gruppenverfahren nachzudenken, wie z. B. Stichprobenbildung und Gruppenzusammensetzung, aber auch die konkrete Datenerhebung und Aspekte des Datenschutzes. Im (in Vorbereitung befindlichen) Folgeartikel zum Thema Gruppendiskussion wird eine theoretische Betrachtung des Begriffs der ‚Gruppe‘ ebenso im Fokus stehen wie die Moderation, unterschiedliche mögliche Auswertungsverfahren/-strategien und der Bereich der qualitativen Online-Forschung.

Published: May 2017

Abstract
Antidesma ghaesembilla is an important medicinal and food plant in many Asian countries. Ten substances could be isolated from the dichloromethane and methanol extract: sitostenone (3), daucosterol (4), chavibetol (5), asperphenamate (6), protocatechuic acid (7), vanillic acid-4-O-β-D-glucoside (8), 1-O-β-D-glucopyranosyl-3-O-methyl-phloroglucinol (9), and aristolic acid II-8-O-β-D-glucoside (10), and two new aristolic acid derivatives, 10-amino-5,7-dimethoxy-aristolic acid II (= 6-amino-9,11-dimethoxyphenanthro[3,4-d]-1,3-dioxole-5-carboxylic acid; 1) and 5,7-dimethoxy-aristolochic acid II (= 9,11-dimethoxy-6-nitrophenantro[3,4-d]-1,3-dioxole-5-carboxylic acid; 2). Exposure to humans of some of these compounds is associated with a severe disease today known as aristolochic acid nephropathy. Therefore, the traditional usage of this plant has to be reconsidered carefully.

AbstractNine new and eleven known phorbol esters were isolated from an acetone extract of the seeds of Croton tiglium. Their structures were determined by extensive analysis of spectroscopic data. Eleven of these compounds were evaluated for their inhibition activity on human tumor cell lines HL-60 and lung carcinoma A549. 12-O-Tiglylphorbol-13-acetate (11), 12-O-(2-methyl)-butyrylphorbol-13-aetate (12), and 12-O-tiglylphorbol-13-isobutyrate (13) exhibited strong inhibition activity against both HL-60 and A549 cell lines with IC50 values ≤ 0.02 and ≤ 0.1 µg/mL, respectively. Compound 18 showed strong inhibition activity against the HL-60 cell line with an IC50 value of 0.02 µg/mL.
Emotions travelling across cultures
Authors: Baicchi Annalisa 
Published: May 2017

AbstractThis article examines the ‘Adjem+PP’ construction in the English-Italian language pair (e.g.,angry at my audacity/arrabbiato per la mia audacia) with the aim of identifying the kinaesthetic embodied schemas that motivate the language of emotions. The analysis of corpus data highlights the interplay between culture and mind, and the cross-linguistic comparison offers some interesting observations that appear to undermine some stereotypes about the way in which emotions are conceived of in the two cultures. Comparative semantics foregrounds the non-diagrammatic rendition in the translation of emotion language and allows for typological hypotheses about cultural cognition and the connection between Talmy’s dichotomy of manner-framed and path-framed languages.
Identity, emotions and cultural differences in English and Polish online comments
Authors: Lewandowska-Tomaszczyk Barbara 
Published: May 2017

AbstractThe focus of the present paper is to examine the extent to which the language used in Computer-Mediated Communication (CMC) and online discourse emotional behavior are good predictors of individual and groupcultural typesand their identities. It is argued that theidentity markingCMC interactants develop has to be stronger, more salient, and, possibly less ambiguous than that used in direct conversation and that theemotionality markersthe users apply in their discussion,particularly those engaging negative emotions and reflecting negative judgments, are argued to be used by online discussants for the purpose of increasing the CMC commentators’conversational visibility. The questions of cultural and linguistic divergence between English and Polish emotional communication patterns are the main points discussed. Three sets of corpus materials are used and the research methodology involves both the qualitative analysis of the emotion types as well as a quantitative (frequency) approach, particularly with respect to culture-specific corpus-generated collocation patterns.
‘This silence doesn’t find favor in my eyes’
Authors: Vardi Ruti 
Published: May 2017

AbstractExamination of the figurative construction [X find favor in Y’s eyes] ([X ffi Y]) in Biblical and Israeli Hebrew reveals semantic and pragmatic differences in its use. In Biblical Hebrew, the construction reflects an ancient cultural conceptualization (Sharifian 2011) ofxen‘favor’ in which it is associated with the eyes of God or humans of high social status. The distribution of [X ffi Y] in this language emphasizes social and cultural hierarchies based on this ancient conceptualization of favor. Although originating from Biblical Hebrew, the use of the construction in Israeli Hebrew does not reflect the ancient conceptualization of xen ‘favor’ that had motivated its emergence. The analysis shows the differences in meaning and pragmatic function of [X ffi Y] in the two language variants, with a focus on contexts of use and the social-cultural identity of participants. This study illustrates the involvement of cultural conceptualization and scenarios in linguistic expression.
Categorial flexibility as an artefact of the analysis
Authors: Palmer Bill 
Published: May 2017

AbstractHoavasaandriahave been analysed as pronouns in some contexts, and articles in others, an apparent case of flexibility in functional categories. However, this analysis depends on an assumption that pronouns are NP head. An alternative analysis employing the Determiner Phrase (DP) demonstrates that in all contextssa/riaoccupy the same syntactic position: DP head. They are always pronouns, alternating with articles in D, an analysis supported by evidence that 1st/2nd pronouns behave in an identical way. This unified analysis gives no grounds for positing membership of separate categories. In contrast, in Standard Fijian (SF) articles and pronouns occupy different syntactic positions: SF pronouns are not in D, but in N. The paper concludes that structures such as DP have considerable descriptive power; pronouns behave variably across Oceanic; and Hoavasa/riaare pronouns in all contexts. Their apparent flexibility was an artefact of earlier analyses, not a feature of the grammar.
Two agreement markers in Austrian Sign Language (ÖGS)
Authors: Krebs Julia , Wilbur Ronnie B. , Roehm Dietmar 
Published: May 2017

AbstractFor many of the sign languages studied to date, different types of agreement markers have been described which express agreement in transitive constructions involving non-inflecting (plain) verbs and sometimes even inflected agreement verbs. Austrian Sign Language (ÖGS) belongs to the group of sign languages employing two different agreement markers (agrm-bc/agrm-mf), which will be described in this paper. In an online questionnaire, we focused on two questions: (i) whether both forms of agreement markers are rated as equally acceptable by Deaf ÖGS-signers and hearing native signers, and (ii) whether there is a preferred syntactic position (pre- vs. postverbal) for these markers. Data analysis confirmed that both agreement markers are accepted by ÖGS-signers and that both agreement markers are slightly preferred in preverbal position. Further, possible origins of both agreement markers are discussed.
Video-Based Electroshocking Platform to Identify Lamprey Ammocoete Habitats: Field Validation and New Discoveries in the Columbia River Basin
Authors: Arntzen Evan V. , Mueller Robert P. 
Published: May 2017

Abstract
A deepwater electroshocking platform (DEP), developed to sample larval lampreys (ammocoetes) and associated habitat in depths up to 15 m, was recently tested in the field. Searches were conducted at a known rearing location (mouth of the Wind River, Washington) and at locations on the Cowlitz River, Washington, where ammocoetes had not previously been found. At the Wind River, video-imaged ammocoetes ranged from 50 to 150 mm in water depths between 1.5 and 4.5 m, and were more common in sediments containing organic silt. Ammocoetes (n = 137) were detected at 61% (summer) and 50% (winter). Following the field verification, the DEP was used on the lower 11.7 km of the Cowlitz River. Ammocoetes (n = 41) were found at 26% specific search locations. Cowlitz River sediment containing ammocoetes was also dominated by silt with organic material, often downstream of alluvial bars in water depths from 0.8 to 1.7 m. Test results indicated the DEP was successful at detecting ammocoetes with little to no impact in relation to other sampling methods. The DEP can also be used to characterize lamprey ammocoete habitats.

Age Validation of Brown Trout in Driftless Area Streams in Wisconsin using Otoliths
Authors: Haglund Justin M. , Mitro Matthew G. 
Published: May 2017

Abstract
Accurate age estimation is important for understanding salmonid population dynamics and managing fisheries. In this study, we validated the age of Brown Trout Salmo trutta in four Driftless Area streams of southwestern Wisconsin using otoliths from known-age fish. We tagged and released known age-1 Brown Trout with coded wire tags in spring 2010–2015. Age-1 Brown Trout were identified by length and verified by identifying a single annulus in a subsample of otoliths. Brown Trout were recaptured 1 to 5 years after tagging to extract otoliths for aging and coded wire tags to identify known age. We used three readers to independently estimate age using otoliths for 249 Brown Trout, and we quantified bias and precision. Complete agreement (all readers assigned the same age) was 74%, partial agreement (at least two readers assigned the same age) was 98%, and consensus agreement with known age (all readers agreed on a consensus on age when assigned ages differed) was 93% with a coefficient of variation of 9.4%. Consensus agreement by age varied from 81% for age 3 (n = 31) to 98% for age 1 (n = 132) and 100% for age 5 (n = 6). We conclude that using otoliths is a valid approach for estimating the age of Brown Trout ages 1–5 in productive streams as found in Wisconsin's Driftless Area and that the use of multiple readers and consensus agreement can improve aging accuracy.

Estimating National-Level Exposure to Antineoplastic Agents in the Workplace: CAREX Canada Findings and Future Research Needs
Authors: Hall Amy L. , Demers Paul A. , Astrakianakis George , Ge Calvin , Peters Cheryl E. 
Published: May 2017

AbstractObjectives:Occupational exposure to antineoplastic agents occurs in various environments and is associated with increased cancer risk and adverse reproductive outcomes. National-level information describing the location and extent of occupational exposure to antineoplastic agents is unavailable in Canada and most other countries. CAREX Canada aimed to estimate the prevalence and relative levels of occupational exposures to antineoplastic agents across work setting, occupation, and sex.Methods:‘Exposure’ was defined as any potential for worker contact with antineoplastic agents. Baseline numbers of licensed workers were obtained from their respective professional bodies. For unlicensed workers, Census data or data extrapolated from human resources reports (e.g., staffing ratios) were used. Prevalence was estimated by combining population estimates with exposure proportions from peer-reviewed and grey literature. Exposure levels (classified as low, moderate, and high) by occupation and work setting were estimated qualitatively by combining estimates of contact frequency and exposure control practices.Results:Approximately 75000 Canadians (0.42% of the total workforce) are estimated as occupationally exposed to antineoplastic agents; over 75% are female. The largest occupational group exposed to antineoplastic agents is community pharmacy workers, with 30200 exposed. By work setting, 39000 workers (52% of all exposed) are located in non-hospital settings; the remaining 48% are exposed in hospitals. The majority (75%) of workers are in the moderate exposure category.Conclusions:These estimates of the prevalence and location of occupational exposures to antineoplastic agents could be used to identify high-risk groups, estimate disease burden, and target new research and prevention activities. The limited secondary data available for developing these estimates highlights the need for increased quantitative measurement and documentation of antineoplastic agent contamination and exposure, particularly in work environments where use is emerging.
Chromatin accessibility prediction via convolutional long short-term memory networks withk-mer embedding
Authors: Min Xu , Zeng Wanwen , Chen Ning , Chen Ting , Jiang Rui 
Published: May 2017

AbstractMotivationExperimental techniques for measuring chromatin accessibility are expensive and time consuming, appealing for the development of computational approaches to predict open chromatin regions from DNA sequences. Along this direction, existing methods fall into two classes: one based on handcrafted k-mer features and the other based on convolutional neural networks. Although both categories have shown good performance in specific applications thus far, there still lacks a comprehensive framework to integrate useful k-mer co-occurrence information with recent advances in deep learning.ResultsWe fill this gap by addressing the problem of chromatin accessibility prediction with a convolutional Long Short-Term Memory (LSTM) network with k-mer embedding. We first split DNA sequences into k-mers and pre-train k-mer embedding vectors based on the co-occurrence matrix of k-mers by using an unsupervised representation learning approach. We then construct a supervised deep learning architecture comprised of an embedding layer, three convolutional layers and a Bidirectional LSTM (BLSTM) layer for feature learning and classification. We demonstrate that our method gains high-quality fixed-length features from variable-length sequences and consistently outperforms baseline methods. We show that k-mer embedding can effectively enhance model performance by exploring different embedding strategies. We also prove the efficacy of both the convolution and the BLSTM layers by comparing two variations of the network architecture. We confirm the robustness of our model to hyper-parameters by performing sensitivity analysis. We hope our method can eventually reinforce our understanding of employing deep learning in genomic studies and shed light on research regarding mechanisms of chromatin accessibility.Availability and implementationThe source code can be downloaded from https://github.com/minxueric/ismb2017_lstm.Supplementary informationSupplementary materials are available at Bioinformatics online.
False discovery rate control incorporating phylogenetic tree increases detection power in microbiome-wide multiple testing
Authors: Xiao Jian , Cao Hongyuan , Chen Jun 
Published: May 2017

AbstractMotivationNext generation sequencing technologies have enabled the study of the human microbiome through direct sequencing of microbial DNA, resulting in an enormous amount of microbiome sequencing data. One unique characteristic of microbiome data is the phylogenetic tree that relates all the bacterial species. Closely related bacterial species have a tendency to exhibit a similar relationship with the environment or disease. Thus, incorporating the phylogenetic tree information can potentially improve the detection power for microbiome-wide association studies, where hundreds or thousands of tests are conducted simultaneously to identify bacterial species associated with a phenotype of interest. Despite much progress in multiple testing procedures such as false discovery rate (FDR) control, methods that take into account the phylogenetic tree are largely limited.ResultsWe propose a new FDR control procedure that incorporates the prior structure information and apply it to microbiome data. The proposed procedure is based on a hierarchical model, where a structure-based prior distribution is designed to utilize the phylogenetic tree. By borrowing information from neighboring bacterial species, we are able to improve the statistical power of detecting associated bacterial species while controlling the FDR at desired levels. When the phylogenetic tree is mis-specified or non-informative, our procedure achieves a similar power as traditional procedures that do not take into account the tree structure. We demonstrate the performance of our method through extensive simulations and real microbiome datasets. We identified far more alcohol-drinking associated bacterial species than traditional methods.Availability and implementationR package StructFDR is available from CRAN.Supplementary informationSupplementary data are available at Bioinformatics online.
