Reconfigurable dipole antenna array with shared parasitic elements for 360° beam steering

Different from the traditional reconfigurable antennas, in which PIN diodes are just used as switches, a novel method for achieving the reactance tuning is proposed, in which the impedance characteristics of the PIN diode in different working states are used to realize elements sharing. The mechanism of element sharing is explained by mathematical analysis, firstly. Then, the novel method of realizing element sharing based on the impedance characteristics of PIN diode is explained. By this way, reactance tuning can be easily achieved using PIN diode. Finally, a 360° beam switchable dipole antenna array is designed to illustrate the feasibility of the proposed method. The results show that gains of 7.8 dBi, and FBRs (front‐to‐back ratios) of greater than 19 dB are achieved by the proposed antenna. In particular, the maximum gain drop of the proposed antenna is less than 0.72 dB when switching between different working modes.
Peak p-values and false discovery rate inference in neuroimaging

Peaks are a mainstay of neuroimage analysis for reporting localization results. The current peak detection procedure in SPM12 requires a pre-threshold for approximating p-values and a false discovery rate (FDR) nominal level for inference. However, the pre-threshold is an undesirable feature, while the FDR level is meaningless if the signal is assumed to be nonzero everywhere. This article provides: 1) a peak height distribution for smooth Gaussian error fields that does not require a screening pre-threshold; 2) a signal-plus-noise model where FDR of peaks can be controlled and properly interpreted. Matlab code for calculation of p-values using the exact peak height distribution is available as an SPM extension.
Actualisation des besoins protéiques des ruminants et détermination des réponses des femelles laitières aux apports de protéines digestibles dans l’intestin

Dans le cadre de la révision des unités d’alimentation des ruminants (projet INRA « Systali »), les besoins protéiques ainsi que les réponses aux variations des apports protéiques ont été actualisés. Le calcul des besoins d’entretien intègre les trois principales voies de pertes obligatoires azotées, qui aboutissent aux besoins protéiques non productifs : les protéines endogènes fécales, les pertes azotées urinaires endogènes et les pertes de protéines par les phanères. Ces actualisations ont été effectuées par approche factorielle et à partir de méta-analyses de larges bases de données de la littérature. Les nouvelles valeurs de ces besoins en protéines digestibles dans l’intestin (PDI) « non productifs » ont ensuite été appliquées à de nombreuses expériences conduites sur vaches ou chèvres laitières avec pour objectif d’étudier les variations des réponses aux apports protéiques. Pour l’estimation de la réponse de l’efficacité des PDI en protéine de lait (EffPDI), il a été décidé d’appliquer une valeur commune pour les différentes productions de protéines ainsi que pour l’accrétion et la mobilisation des protéines corporelles, liées au bilan d’énergie. EffPDI est une fonction décroissante non linéaire de la concentration en PDI, identique entre les vaches et les chèvres. Il est aussi possible de prédire la réponse de la production des protéines laitières en fonction du niveau d’apport des PDI disponibles et en utilisant, comme situation pivot, soit la production pour EffPDI = 67%, soit le potentiel de production. Les données recueillies ont également permis de calculer, de façon factorielle, les pertes azotées urinaires dont les deux principales causes sont l’inefficacité des PDI et l’état nutritionnel azoté du rumen évalué par le critère de la balance protéique du rumen (BalProRu).
Anomaly detection in large-scale networks: A state-space decision process

Abstract A new data fusion and network analytics framework is proposed that is based on the topology of large-scale networks and the stochastic dependencies between nodes, edges, and sensor data. The framework can transform real-time sensor data collected from disparate sources in a network to detect the location of anomalies and the nodes that are impacted by the detected anomalies. By intelligently fuzing multidimensional sensor data based on the topology of a large-scale network, this article also contributes to big data analytics for network systems. We will show that the proposed framework not only brings computational benefits, but also results in better anomaly estimates leading to lower false alarm rates and higher detection rates.
Macrophages Switch to an Osteo‐Modulatory Profile Upon RANKL Induction in a Medaka (Oryzias latipes) Osteoporosis Model

In mammals, osteoclasts differentiate from macrophages in the monocyte lineage. Although many factors driving osteoclast formation are known, the detailed processes underlying precursor recruitment, differentiation, and interaction of macrophages with other cell types involved in bone remodeling are poorly understood. Using live imaging in a transgenic medaka osteoporosis model, where ectopic osteoclasts are induced by RANKL expression, we show that a subset of macrophages is recruited to bone matrix to physically interact with bone‐forming osteoblast progenitors. These macrophages subsequently differentiate into cathepsin K‐ (ctsk‐) positive osteoclasts. One day later, other macrophages are recruited to clear dying osteoclasts from resorbed bone by phagocytosis. To better understand the molecular changes underlying these dynamic processes, we performed transcriptome profiling of activated macrophages upon RANKL induction. This revealed an upregulation of several bone‐related transcripts. Besides osteoclast markers, we unexpectedly also found expression of osteoblast‐promoting signals in activated macrophages, suggesting a possible non‐cell autonomous role in osteogenesis. Finally, we show that macrophage differentiation into osteoclasts is dependent on inflammatory signals. Medaka deficient for TNFα or treated with the TNFα‐inhibitor pentoxifylline exhibited impaired macrophage recruitment and osteoclast differentiation. These results show the involvement of inflammatory signals and the dynamics of a distinct subset of macrophages during osteoclast formation. © 2020 The Authors.

Z‐shaped gate TFET with horizontal pocket for improvement of electrostatic behavior

In this paper, a new Z‐shaped gate TFET structure is proposed with an n+ horizontal pocket insertion beneath the source. The Z‐TFET structure provides higher ON current by 2‐decades as compared to conventional TFET due to the vertical tunneling and presence of HfO2 gate oxide. Similarly, the ambipolar current reduces by 2‐decades without affecting subthreshold swing (SS) and OFF current significantly. The ON current is further improved by positioning a horizontal pocket layer in the source. The impact of horizontal pocket (HP) concentration and thickness on the analog performance is investigated further using a TCAD device simulator. The simulated results reveal the superiority of the proposed ZHP‐TFET device in terms of ON current (higher by seven times) and average SS (reduces by 13%) as compared to Z‐TFET keeping ambipolar current constant. The ambipolar current can be further reduced by optimizing the length of the back gate. Thus, the proposed device is capable of providing higher ION/IOFF (~1012), ION/IAMB (~109) ratio, and transconductance with improved average SS of 45 mV/decade.
Factors Affecting the Dividend Payout Ratio of Agriculture and Mining Companies

The main purpose of this research was to determine the effect of Cash Ratio (CR), Sales Growth (SG), and Investment Opportunity Set (IOS), on Dividend Payout Ratio (DPR). This quantitative research used a sample of 18 agriculture and mining companies listed in Indonesia Stock Exchange (IDX) within the period of 2013-2017. The data used in this research were ssecondary data such as financial statement and annual reports. Data analysis employed panel data regression test with Eviews program version 10. The results of hypothesis testing show that cash ratio has a significant and positive effect on dividend payout ratio, but sales growth and investment opportunity set do not have a significant effect on dividend payout ratio. Meanwhile, the simultaneous hypothesis results show that cash ratio, sales growth, and investment opportunity set have an effect on dividend payout ratio. This study adds new independent variables that are different from the reference research, namely the cash ratio and investment opportunity set.
"It felt like I was part of the data": Comparing Mouse, Touch, and Physical Interaction with Visualizations

With my two exploratory studies I contribute a deeper understanding of the different experiences people have when manipulating data representations using mouse, touch, and physical interaction. To uncover experiences rather than performance measures I employed two different methodologies in the context of “data connectedness. ” My first study used Likert-based questionnaires to determine differences in how connected participants felt to the data they were interacting with. To gain a deeper understanding, my second study employed a word selection activity (using the Desirability Toolkit), which led to much richer data. I found that people associated words like “engaged,” “direct,” and “satisfying” with touch and physical interaction, but often used words like “awkward,” “dull,” and “distant” with the mouse. My findings help to tease apart the characteristics of experienced interaction modalities in relation to how people feel about their connection to the data. Furthermore, my work provides a deeper look into how to measure abstract concepts such as connectedness that are highly elusive but important to understanding why certain ways of interacting with data may be more attractive, more liked, or even more effective.
Simultaneously operating threats cannot predict extinction risk

Species afflicted by multiple threats are thought to face greater extinction risk. However, it is not known whether multiple threats operate antagonistically, additively, or synergistically, or whether they vary across different taxonomic and spatial scales. We addressed these questions by analyzing threats to 10,378 species in six vertebrate classes at global and regional spatial scales using network analysis. The total number of threats was a poor predictor of extinction risk, and particular combinations of threats did not predict extinction risk in the same way at different spatial scales. The exception was cartilaginous fishes, which faced increased extinction risk with increasing numbers of threats. Except for cartilaginous fishes, our findings indicate that species facing more threats than others do not face a higher risk of extinction and suggest that effective conservation will require more investment in identifying how threats and different ecosystem stressors operate together at local scales.

Objective: This paper aims to evaluate the success rate of vesicovaginal fistula (VVF) repair surgery by transvaginal (TVAG) and transabdominal (TPA) procedure. Method: Literatures were searched on the online database, PUBMED and Google Scholar. All of the studies should be belonging on to inclusion criteria. The literatures had qualitative analyze by the authors and bias criteria based on Review Manager 5.3 application. It also had quantitative analyzed by the same application. Results: The literatures have 191 patients (transvaginal-n=107; transabdominal-n=84). The data was homogen (Chi2 0,05). The forest plot showed that TPA has a higher success rate than TVAG, still not statistically significant (test overall effect P>0,05; 95%CI was 0,59 to 5,30). Conclusion: Transabdominal procedure has a higher success rate.
Senpai: Learner Responses to a Near-Peer Role Modeling Intervention

Though Japanese learners often express a preference for so-called “native” English teachers, a growing body of research indicates that their development of multilingual identity is more positively influenced by those with whom they readily identify—other successful Japanese learners. This mixed methods study, conducted in tandem with an existing communication strategy curriculum, explored university students’ responses to a “near-peer role modeling” intervention combining prerecorded video with reflective practice. Participants included two groups, both majoring in Japanese, enrolled in a compulsory 1st-year English conversation tutorial course. Results indicate that less confident students may experience positive belief changes and increased classroom participation following exposure to near-peer role models. More confident learners did not exhibit these changes to a significant degree. Moreover, following this intervention, lower-performing students responded more positively to statements expressing self-efficacy. Participants’ use of Japanese respect language may illuminate to what extent near-peers are valued as role models. 日本の学習者達は「英語母語話者」である英語教師から指導を受ける事が理想的だという意見をよく示すが、近年の研究調査では、学習者にとって最もお手本となる人物は自身の身近に存在する英語を使いこなす日本人英語学習者(NPRM)であると主張されている。 本研究では、混合研究法を用い1学期間のNPRM活動を通して学習者の信念の変化を探究した。 映像と反省的実践を用いた実験的手法は、既存の会話手法習得の為のカリキュラムと並行して導入された。 結果として、英語能力に自信のない学習者達は模範的な日本人から受ける自己効力感について肯定的な変化を示し、学習活動への参加が増加した。 一方で、英語能力に自信のある学習者達は明確な変化を示さなかった。 量的な結果は面談調査と映像を見た後の学習者による感想文を用いた質的データにより解釈が可能となった。 参加者たちが使用する日本語の尊敬語である先輩という表現はどの級友がロールモデルであると理解されているかの程度を示している。 本研究は独特な教育環境によって行われた為、更なる詳細な研究調査が必要となるだろう。
A 8.5 to 11.6 GHz digitally controlled variable gain amplifier with 15‐dB gain range and 1‐dB step

A X‐band variable gain amplifier (VGA) with low phase variation and high control resolution is presented in 180‐nm CMOS. The linear gain VGA and current‐type digital‐to‐analog converter (DAC) are implemented to improve the accuracy of gain control and the robustness against process, supply voltage, and temperature variations (PVT). The measured peak gain and 3‐dB bandwidth are 8 dB and 8.5 to 11.6 GHz, respectively. The gain range is 15 dB with a gain step of 1 dB. With a supply voltage varying from 1.6 to 2.0 V, the root‐mean‐square (RMS) gain and phase errors in 3‐dB bandwidth are <0.62 dB and <1.5°, respectively. With supply of 1.8 V, the measured root‐mean‐square (RMS) gain and phase errors across −25 to 110°C are <0.65 dB and <1.7°, respectively. Comparing the measurement results of five chips, the variation of RMS gain error is <0.24 dB, and the RMS phase errors are almost the same. The measurement results demonstrate the proposed VGA is very suitable for phased arrays in X‐band.
An Adaptive Distance Protection Scheme for High Varying Fault Resistances

The variation of fault resistances introduces error in the measured apparent impedance of the conventional distance protection scheme. With this, the measured apparent impedance at the relay location is not proportional to its length. This paper presents an adaptive protection scheme using Artificial Neural Network (ANN) to address the problem. A MATLAB based adaptive distance relaying scheme is proposed using the ANN feed-forward nonlinear supervised back-propagation algorithm based on the Levenberg-Marquardt network topology. The PSCAD /EMTDC software is used to generate the current and voltage signals for specified transmission lines which are used for subsequent ANN training and testing of the proposed algorithm. The proposed non-conventional adaptive scheme was validated with a new set of high fault resistances data using the proposed model. The results show the ability of ANN to correctly detect, classify and localized fault under varying fault resistance.
Hard-of-Hearing Individuals’ narratives of Inclusion and Exclusion about their schooled EFL learning

This paper deals with research on inclusion concentrating on the pedagogical implications derived from a qualitative case study that looked into three hard-of-hearing (HHs) students’ perspectives and retrospectives on their schooled EFL learning. Data came from narratives gathered in autobiographical writings and interviews. Although there is a good body of literature on pedagogy in terms of strategies for dealing with HHs, few works have counted on the student’s perspectives. The authors’ insights, one of them being hard-of-hearing, call for truly inclusive policies and practices that address the categories developed in this case study, namely: 1. Deafness separates HHs from people. 2. Hearing aids are not like glasses, and 3. An exemption is not inclusion. The authors feel that the recommendations made are valid for learners with or without disabilities.
Parent experience of the national disability insurance scheme (NDIS) for children with hearing loss in Australia

Abstract The introduction of a National Disability Insurance Scheme (NDIS) in Australia has changed the basis of service provision for people with disability. This mixed-methods study presents the experiences of parents of children with hearing loss during national rollout of the NDIS. Surveys were completed by 100 parents, with 57 parents reporting their child received NDIS funding. Individual interviews of seven parents in different locations provided further information. Between-group comparisons were made and regression analysis examined the influence of parental disadvantage on NDIS experiences. Qualitative data were analysed for themes and findings were triangulated. The NDIS has improved services for some children with hearing loss but initial access and ongoing navigation can be challenging for others. Barriers included a complicated system, planning delays, poor communication and uninformed National Disability Insurance Agency (NDIA) staff. This study suggests areas of refinement and further investigation that may improve services for children with hearing loss. Points of interest Parents of children with hearing loss in Australia had difficulty accessing the National Disability Insurance Scheme (NDIS) due to poor communication and delays. Parents reported the NDIS system was challenging and felt they needed high levels of education and advocacy skills to navigate the system and prepare information to justify necessary disability supports for their child. Parents were concerned that disadvantaged families would not receive adequate supports for their child with hearing loss due to the complexity of the NDIS. This small-scale national study indicates that recent and upcoming changes to the NDIS should be evaluated to ensure children with hearing loss can access equivalent funding packages and services regardless of family circumstances.
A Curated Chronology: Traits of Electro-Energy from Research-through-Design Practices

: Over the past two decades a number of design-led projects undertaken on the topic of energy research have contributed to the research-through-design domain. We present selected studies from design and HCI undertaken as research-through-design on the topic of energy as a curated chronology. Four design practice-based research groups from different global regions engaging with energy related issues are discussed in a chronological presentation. Using descriptive analysis of these projects we interpret four specific traits of design for approaching energy as a design subject. The interpretation is presented through tracings of traits and are analysed in a sequence. Building such a curated chronology of prior projects we generate an approach for designing a relation building consumer reward system for a project on wind-based electricity production. With this we show that such a curated chronological approach can be interpretive and generative, complimenting and strengthening conventional literature reviews when undertaking research-through-design projects.
Demonstration of Solitary Chemosensory Cells in the Nasopalatine and Vomeronasal Ducts of Rat by a-gustducin and GAP-43 Immunohistochemistry

In the present study, we used immunohistochemistry for α - gustducin and Growth Associated Protein-43 (GAP-43) to examine the spatial distribution of the solitary chemosensory cells primarily in the nasopalatine ducts of rat at the time of weaning, which is lack in the literature. Methods: We found abundant solitary cells labeled with α- gustducin in the nasopalatine duct and vomeronasal organ of rats. In the nasopalatine duct, these cells were more frequent in the medial wall epithelium; meanwhile appreciable number of α-gustducin labeled cells were localized only in the neuroepithelium portion of the vomeronasal organ. We found the number of these cells increased toward the entries of the nasopalatine and vomeronasal ducts into the nasal cavity. We also found GAP-43 heavily expressed in the core of nasopalatine duct, close to the basement membrane and around the blood vessels and cavernous spaces of the vomeronasal organ. Results: GAP-43 labeled axons apposed the solitary chemosensory cells closely, either coursing along or wrapping the solitary chemosensory cells. Individual cells were apposed by one or a few intraepithelial nerve fibers and a single fiber sometimes contacted a few solitary chemosensory cells. Intraepithelial GAP-43 labeled fibers were more frequent toward the nasal cavity and the entry of nasopalatine and vomeronasal ducts in close association with the solitary chemosensory cells. Conclusion: We conclude that α -gustducin-expressing cells alongside the GAP-43 intraepithelial nerves in the nasopalatine and vomeronasal ducts suggests that they share the same transduction mechanisms.
Integrated agricultural management practice improves soil quality in Northeast China

ABSTRACT Sustainable agricultural management practices have attracted increasing attention due to their significant roles in benefiting the functions and sustainability of agro-ecosystems. An integrated agricultural practice (IP) in a maize cropping system was developed by changing row spacing, adopting no-tillage and residue return in the Northeast China. A 12-year field study was carried out to evaluate the effect of IP and conventional practice (CP) on soil physical properties, microbial biomass and enzyme activity during the cropping season. The results showed that soil organic matter under IP was increased by 17.4, 9.88 and 6.69% in June, August and October, respectively, than CP. IP enhanced microbial biomass C (by 31.7, 25.1 and 30.4% in June, August and October) and activities of invertase, urease and phosphatase (by 27.2–38.0, 78.9–182 and 9.8–29.0%) compared to CP, possibly attributing to an increase in the soil microbial community. Furthermore, the soil pH, water content, nitrogen and phosphorus contents, microbial biomass and some specific enzyme activities varied with sampling time. It is concluded that IP improved soil quality and health by increasing organic matter content and microbial biomass and activity in maize field in Northeast China, suggesting that IP is a feasible management technology for sustainable agriculture.
Enhancing the Convective Heat Transfer Coefficient Using a Single or Doubled Strainers

Numerical investigation has been employed using Lattice Boltzmann Model (LBM) to investigate a temporal and a spatial characteristics of the flow past over a single and doubled strainers confined in a channel. A two dimensional nine directional (D2Q9) lattice arrangements is employed. The single and doubled strainers have been considered for Reynolds numbers Re=100. Flow and temperature field of a single and doubled strainers have been predicted. The local and the average Nusselt number have been evaluated for a single and a doubled arrangement of strainers. The results illustrate the effect of the porosity of the strainer on the local and the average Nusselt number. Consequently, a strainer enhances the heat transfer coefficient inside the A/C duct.
