Universal features of hydrogen absorption in amorphous transition-metal alloys.

We propose that all A/sub 1-//sub x/B/sub x/ glasses (where A (B) is a late (early) transition metal) are structurally isomorphic, chemically random alloys which store hydrogen in tetrahedral interstitial sites A/sub 4-//sub n/B/sub n/ (in decreasing order n = 4,3,2,. . . ). The maximum absorbed hydrogen-to-metal atomic ratio within each type of interstitial site is 1.9(/sub n//sup 4/)x/sup n/(1-x)/sup 4-n/ ((/sub n//sup 4/) = 4exclamation/nexclamation(4-n)exclamation) independent of alloy and temperature. The chemical potential as a function of hydrogen concentration within a single site type n is also independent of composition and temperature. The only nonuniversal feature is the dependence of the typical site energies E/sub n/ of the type-n sites on the A and B atoms, which may, however, be estimated from crystalline hydride properties.
The burden of chronic pain after major head and neck tumor therapy

Introduction: Little is known about the burden of chronic pain after major head and neck tumors' therapy. In this study, we aimed to estimate the prevalence of chronic pain, explore the factors associated with the presence of chronic pain, and assess the consequences of chronic pain on the patients' quality of life. Methodology: This was a cross-sectional survey among patients who had completed their therapy (e.g., surgery, radiotherapy, and chemotherapy) for major head and neck (larynx, nasopharynx, oropharynx, hypopharynx, oral cavity, tongue, and sinuses) tumors after at least 3 months. We collected relevant demographic and clinical data and administered the Brief Pain Inventory-Short Form, Neuropathic Pain Questionnaire-Short Form, and Pain Catastrophizing Scale questionnaires. Possible risk factors were explored using a classification tree model. Results: A total of 102 patients (59 men, 42 women) were enrolled in this study between 3 and 72 months after tumor treatment. 30% of the patients reported having chronic pain after their major head and neck tumors' therapy. The average pain score in the last 24-hr was 3.4 (standard deviation = 2.7). The prevalence of patients with chronic pain was higher (42%) among those who had surgery. Factors associated with chronic pain were female sex, older age, surgery, advanced cancer stage, and radiotherapy. Patients who reported having chronic pain also reported having a lower quality of life manifested by impairments in general activity, mood, walking ability, normal work, and sleeping. Patients who reported having chronic pain had higher Pain Catastrophizing Scale scores. Conclusion: Our study highlighted the high burden of chronic pain after therapy for major head and neck tumors. We identified demographic and clinical factors that are associated with the presence of chronic pain. Further studies are required to better understand the risk factors to implement strategies to prevent, alleviate, and treat chronic pain associated with major head and neck tumor therapies.
Unwrapping eddy current compensation: Improved compensation of eddy current induced baseline shifts in high‐resolution phase‐contrast MRI at 9.4 tesla

Phase‐contrast MRI (PC‐MRI) is a versatile tool allowing evaluation of in vivo motion, but is sensitive to eddy current induced phase offsets, causing errors in the measured velocities. In high‐resolution PC‐MRI, these offsets can be sufficiently large to cause wrapping in the baseline phase, rendering conventional eddy current compensation (ECC) inadequate. The purpose of this study was to develop an improved ECC technique (unwrapping ECC) able to handle baseline phase discontinuities.
Exploring the Role of IS in Dynamic Capabilities

Resource-based theory suggests that firms develop idiosyncratic capabilities that contribute to sustainable competitive advantage when they are valuable, rare, inimitable and non-substitutable. The successful use of information systems IS and information technology IT has been linked to improved firm performance. Recent literature suggests that a deeper understanding of what capability means in practice may be gained from a disaggregation into component competences and resources. A better understanding of the role of IS/IT in business level capability may be achieved through a fuller articulation, both of the capability itself, and the contribution of IS/IT, together with an evaluation of the effectiveness in delivering sustainable competitive advantage. A dynamic capabilities perspective explains the way firms adapt capabilities to changing market environments over time. This paper explores these propositions through an exploratory case study using a framework derived from a resource-based and systemic view of the firm. The analysis suggests a dynamic Capability Development Model through which the implications and potential for IS and IT over time may be understood. The paper addresses three issues. First, it offers a better articulation of what capability concepts mean in practice. Second, it takes a disaggregated understanding of capabilities, and third, it sheds light on the dynamics of capabilities.
Multiobjective Electromagnetic Optimization Based on a Nondominated Sorting Genetic Approach With a Chaotic Crossover Operator

Real-world engineering optimization problems involve multiple design factors and constraints and consist in minimizing multiple noncommensurable and often competing objectives. In recent years, many evolutionary techniques for multiobjective optimization have been proposed. In this context, the Non-dominated Sorting Genetic Algorithm II (NSGA-II) algorithm is an effective methodology to solve multiobjective optimization problems. A modified NSGA-II to seek the Pareto front of electromagnetic multiobjective design problems is proposed in this paper. We propose the use of chaotic sequences based on Zaslavskii map in the NSGA-II crossover operator. The proposed method is tested on TEAM 22 benchmark optimization problem with promising results.
Differentiated Human Alveolar Type II Cells Secrete Antiviral IL-29 (IFN-λ1) in Response to Influenza A Infection1

Alveolar type II epithelial cells (ATIIs) are one of the primary targets for influenza A pneumonia. The lack of a culture system for maintaining differentiated ATIIs hinders our understanding of pulmonary innate immunity during viral infection. We studied influenza A virus (IAV)-induced innate immune responses in differentiated primary human ATIIs and alveolar macrophages (AMs). Our results indicate that ATIIs, but not AMs, support productive IAV infection. Viral infection elicited strong inflammatory chemokine and cytokine responses in ATIIs, including secretion of IL-8, IL-6, MCP-1, RANTES, and MIP-1β, but not TNF-α, whereas AMs secreted TNF-α as well as other cytokines in response to infection. Wild-type virus A/PR/8/34 induced a greater cytokine response than reassortant PR/8 virus, A/Phil/82, despite similar levels of replication. IAV infection increased mRNA expression of IFN genes IFN-β, IL-29 (IFN-λ1), and IL-28A (IFN-λ2). The major IFN protein secreted by type II cells was IL-29 and ATIIs appear to be a major resource for production of IL-29. Administration of IL-29 and IFN-β before infection significantly reduced the release of infectious viral particles and CXC and CC chemokines. IL-29 treatment of type II cells induced mRNA expression of antiviral genes MX1, OAS, and ISG56 but not IFN-β. IL-29 induced a dose-dependent decrease of viral nucleoprotein and an increase of antiviral genes but not IFN-β. These results suggest that IL-29 exerts IFN-β-independent protection in type II cells through direct activation of antiviral genes during IAV infection.
Advocacy: a conceptualization for social work practice.

view of the specific methods that an a vocate should use, but this is not the case. Many authors focus on one method of advocacy to the exclusion of others. For example, some consider only class advocacy, and others con sider only case advocacy.4 Some claim that conflict is always necessary to advocacy; others believe that conflict should always be minimized.5 Some believe that advocacy must be based on the worker's decisions concerning what should be advocated; others claim that the task of advocacy is to persuade, not to decide.6 Logic and experience dictate that each method has some use and that methods
Monoclonal and polyclonal antibodies against Epstein-Barr virus nuclear antigen 5 (EBNA-5) detect multiple protein species in Burkitt's lymphoma and lymphoblastoid cell lines

The Epstein-Barr virus nuclear antigen 5 (EBNA-5) is encoded by highly spliced mRNA from the major IR1 (BamHI-W) repeat region of the virus genome. A mouse monoclonal antibody, JF186, has been raised against a synthetic 18-amino-acid peptide deduced from the EBNA-5 message of B95-8 and Raji cells. The antibody showed characteristic coarse nuclear granules by indirect immunofluorescence and revealed multiple EBNA-5 species by immunoblotting and immunoprecipitation. The B95-8 line itself and all B95-8 virus-carrying cells, whether lymphoblastoid cell lines or in vitro-converted sublines of Epstein-Barr virus (EBV)-negative Burkitt's lymphoma (BL) lines, were EBNA-5 positive. Among 36 cell lines carrying different EBV strains, only 10 expressed the B95-8-Raji-prototype EBNA-5 recognized by JF186; this was probably due to genetic variation in the epitope recognized by JF186, as shown for P3HR-1. Human antibodies, affinity purified against EBNA-5-JF186 immunoprecipitates, detected EBNA-5 in the majority of EBV-positive BL lines and in all lymphoblastoid cell lines containing the BL-derived viruses. Thus, EBNA-5 can be expressed by all virus isolates examined, but is down-regulated, together with other latent gene products, in a minority of BL lines which have a particular cellular phenotype. EBNA-5 was detected as a ladder of protein species of 20 to 130 kilodaltons (kDa), with a regular spacing of 6 to 8 kDa, consistent with the coding capacity of the combined BamHI-W 66- and 132-base-pair exons, together with shifts of 2 to 4 kDa, consistent with the size of the separate 66- and 132-base-pair exons. Multiple EBNA-5 proteins can be expressed by the single cell as shown by cloning of newly infected cells.
How to set up a local cluster with optimal member nodes in wireless sensor networks

Wireless sensor networks are networks for collecting environment information in specific area using sensor nodes with low power. The process of sensor networks is a multiphase process compromised of sensing environment, transmitting the sensing data to neighbor nodes, collecting it from nodes for aggregating, and processing it for a request. As sensor networks have a feature which can have many similar data between adjacent nodes, they use a clustering method which sets up a cluster heads, collects many similar data from member nodes in a local cluster and sends the collected data to sink by cluster heads. A clustering method of sensor networks needs to equally distribute member nodes to a cluster head because of affecting the number of member nodes in a local cluster to the energy consumption of a cluster head, a local cluster and sensor network. So, this paper proposes how to set up a local cluster with optimal member nodes in wireless sensor networks.
A broadband circularly-polarized antenna with wide axial-ratio beamwidth

A broadband circularly polarized antenna with wide axial-ratio beamwidth utilizing a wideband power divider network is presented. The vertical and horizontal paired-dipoles are used as the antenna elements, which are excited by a 1-to-4 sequential broadband feeding network. Through a rational design of the spacing between two parallel dipoles and the feeding network, an antenna with broad impedance and axial-ratio bandwidth and wide 3-dB axial ratio beamwidth is achieved. A prototype of the proposed antenna is designed, fabricated, and tested. It can achieve a measured impedance bandwidth for VSWR≤1.5 of 67.9% and a 3-dB axial-ratio bandwidth of 42.5%. Moreover, the antenna has wide 3-dB axial ratio beamwidth of more than 120° ranging from 1.16 to 1.46 GHz. The proposed antenna is low profile, and can be built using low-cost printed circuit fabrication methods.
Battered women: a health care problem in disguise.

Women should have the right to move about within the confines of their homes among those persons with whom they share the most intimate, interpersonal relationships without fearing for their safety and well-being, for life itself. In general women accept and expect that right as a given; however recent studies cited by Davidson (1978) from the National Institute of Mental Health suggest that 50%-60% of all American marriages have experienced at least one incident of minor battering or assault upon the female in the relationship. Understated estimates report greater than three to four million American women are battered on more than one occasion each year (Iver, 1980; Stark, Flitcraft & Fraxier, 1979). The Crime Index of the Federal Bureau of Investigation (1980) reported the incidence of wife beating to be greater than that of rape, another act of violence that frequently goes unreported. The estimates of the Index project the incidence to be ten times more common than official figures indicated. One of the myths surrounding battered women is that it is a lower socioeconomic phenomenon. This assumption interferes with the ability of middle-class and upper-class health care providers to confront the universality of the problem. Citing Fairfax County, Virginia, one of the wealthiest counties in the United States, Martin (1976) reported that during 1974 there were at least 30 assault warrants sought each week by Fairfax County wives, with police receiving approximately 400 family disturbance calls per month. Lichtenstein (1981) echoed the beliefs of victims and many professionals when she stated, “Medical agencies usually only treat physical injuries and do very little to prevent the problem” (p. 241). A study done by Rounsaville and Weismann (1977-1978) revealed that battered women reflect 3.5% of the emergency room population. Tracking twenty women previously treated in an emergency room for injuries secondary to battering, only three medical records included any mention of abuse. Health care providers seem to be more comfortable accepting spurious explanations than probing for the truth. According to Martin (1976), “Even if they suspect that a woman’s injuries are due to a beating they seldom want to risk personal involvement by asking questions” (p. 12). Parker and Schumacher (1977) emphasized the “long suffering inattention to battered women from social agencies and the health care system” (p. 760).
Developing built in test to meet the demands of the product test lifecycle

Companies are incorporating Built-In-Test (BIT) capabilities into their products to 1) reduce the need for external Special Test Equipment (STE), 2) incorporate test capability for all levels of manufacturing test from Circuit Card Assembly (CCA) to the finished product, 3) decrease the test/diagnostics cycle time, and 4) product logistics test needs in the field. Customer BIT requirements are typically phrased as “BIT shall be used as the final verification of the product assembly” or “The product shall have a 95% BIT coverage”. These vague requirements can leave the BIT Developer overwhelmed with the interpretation of the “how” to create a BIT or “what is BIT” to successfully meet the customer's needs. This paper provides a BIT development methodology and process that defines the “how” and “what” to meet both the needs of the customer and to provide beneficial capabilities to increase product test effectiveness while decreasing cost of test. The “how” defines the development process of Built-in-Test artifacts as it progresses through the various development phases: requirements derivation, design evolution, test integration and validation, and finally deployment for production and field maintenance. The “what” discusses the selection and definition of Built-in-Test artifacts for the product, selected through design methodologies such as testability design and modeling analyses.
An Accurate Physics-Based Compact Model for Dual-Gate Bilayer Graphene FETs

In this paper, an accurate compact model based on physical mechanisms for dual-gate bilayer graphene FETs is presented. This model is developed based on the 2-D density of states of bilayer graphene and is implemented in Verilog-A. Furthermore, physical equations describing the behavior of the source and drain access regions under back-gate bias are proposed. The accuracy of the developed large-signal compact model has been verified by comparison with measurement data from the literature.
Non-Markovian Control with Gated End-to-End Memory Policy Networks

Partially observable environments present an important open challenge in the domain of sequential control learning with delayed rewards. Despite numerous attempts during the two last decades, the majority of reinforcement learning algorithms and associated approximate models, applied to this context, still assume Markovian state transitions. In this paper, we explore the use of a recently proposed attention-based model, the Gated End-to-End Memory Network, for sequential control. We call the resulting model the Gated End-to-End Memory Policy Network. More precisely, we use a model-free value-based algorithm to learn policies for partially observed domains using this memory-enhanced neural network. This model is end-to-end learnable and it features unbounded memory. Indeed, because of its attention mechanism and associated non-parametric memory, the proposed model allows us to define an attention mechanism over the observation stream unlike recurrent models. We show encouraging results that illustrate the capability of our attention-based model in the context of the continuous-state non-stationary control problem of stock trading. We also present an OpenAI Gym environment for simulated stock exchange and explain its relevance as a benchmark for the field of non-Markovian decision process learning.
Intelligibility of foreign-accented words: Acoustic distances and gradient foreign accentedness

Intelligibility and degree of accentedness are interrelated aspects of non-native speech. Previous research suggests that foreign accentedness is influenced by phonetic distance measures [7]. These distance measures may also influence the intelligibility of individual words. In the present study we further investigate the relationship between the intelligibility of nativeand Mandarin-accented English words and acoustic distance measures (both spectral and temporal). We also examine the functional relationship between intelligibility and ratings of foreign accentedness assigned to the same words. Intelligibility was based on transcription accuracy scores and acoustic distances were based on formant and duration measurements in relation to mean values from a set of native talkers. The results indicate that temporal and spectral distances influence word intelligibility and that the functional relationship between intelligibility and accentedness is non-linear.
Study on diagnosis of power transformer winding deformation through vibration signal

As one of the most important equipment in power system, power transformer plays a major role in guarantying the safe and stable operation of power system. Among the faults in transformer, winding deformation takes a large part. Since 1970s, lots of method, such as Frequency Response Analysis, Low Voltage Impulse have been put into winding deformation detection. Among these methods, Vibration Analysis from oil tank has gained much attention through its advantage that it is closely related with the mechanical condition of winding and core and can be used in on-line monitoring. This paper based on the mechanism of transformer vibration and Fourier Transform, choose Fundamental Frequency of Vibration (FFV), Maximum Amplitude in Frequency spectrum (MAF) and Transformer Vibration Entropy (TVE) as vibration eigenvalue to indicate the mechanical condition of transformer. What's more, the failure threshold for diagnosis is acquired through 78 power transformer varying from 110kV to 750kV, single phase to three phase. Among the test results, the vibration eigenvalue from one 110kV power transformer who suffered an external short-circuit accident shows that the winding of 3 phases all have winding deformation. The conclusion and diagnosis results are proved to be effective after the transformer is sent back to the manufacturer and make a pendant-core examination. The diagnosis method for power transformer in this paper based on tank vibration can make contributions to condition monitoring.
Direct Voltage Control of DC–DC Boost Converters Using Enumeration-Based Model Predictive Control

This paper presents a model predictive control (MPC) approach for dc-dc boost converters. A discrete-time switched nonlinear (hybrid) model of the converter is derived, which captures both the continuous and the discontinuous conduction mode. The controller synthesis is achieved by formulating an objective function that is to be minimized subject to the model dynamics. The proposed MPC strategy, utilized as a voltage-mode controller, achieves regulation of the output voltage to its reference, without requiring a subsequent current control loop. Furthermore, a state estimation scheme is implemented that addresses load uncertainties and model mismatches. Simulation and experimental results are provided to demonstrate the merits of the proposed control methodology, which include a fast transient response and a high degree of robustness.
A low operating power FinFET transistor module featuring scaled gate stack and strain engineering for 32/28nm SoC technology

We show that FinFET, a leading transistor architecture candidate of choice for high performance CPU applications [1–3], can also be extended for general purpose SoC applications by proper device optimization. We demonstrate superior, best-in-its-class performance to our knowledge, as well as multi-Vt flexibility for low-operating power (LOP) applications. By high-k/metal-gate (HK/MG) and process flow optimizations, significant drive current (ION) improvement and leakage current (IOFF) reduction have been achieved through equivalent oxide thickness (EOT) scaling and carrier mobility improvement. N-FinFET and P-FinFET achieve, when normalized to Weff (Weff=2xHf+Wf), ION of 1325 µA/µm and 1000 µA/µm at 1 nA/µm leakage current under VDD of 1 V, and 960 uA/um and 690 uA/um at 1 nA/um under Vdd of 0.8V, respectively. This FinFET transistor module is promising for a 32/28nm SoC technology.
