A Wireless Tactile Communication System for Conveying U.S. Army Hand-Arm Signals

Combat conditions place fearsome extremes on soldier senses, rendering many traditional visual and auditory informational pathways unusable for soldier communications. To circumvent these limitations, vibrotactile displays may offer environmental advantages (covert use in murky and noisy conditions) as well as human information processing advantages (an unimpeded sensory channel and potential resource pool). The demonstrated system uses wireless electronic communications to present exemplar Army arm and hand signals in a tactual form. Vibrotactors on an elasticized belt deliver vibrotactile patterns to the wearer's torso, with inputs originating from a hardened PDA running a custom software package. Benefits and limitations are discussed, as well as other potential applications and integrations with other information input sources.
SEE characterization of vertical DMOSFETs: an updated test protocol

The test protocols for power MOSFETs used in the manufacturer's specification sheets are inadequate in that they do not represent a realistic worst-case condition. In addition, the applicable single-event effects (SEE) test methods and guidelines do not provide sufficient details to the user as to what conditions should be used, placing an undue burden on them. This paper addresses several of these deficiencies and others. We present a new test protocol; we suggest a new approach to describe the SEE response; and we provide a model to predict critical ion energies that should produce a worst-case response.
Automatic number-plate recognition

The objective of the research is to develop a computer-vision based automatic vehicle identification system to achieve vehicle identification using optical character recognition (OCR) techniques. The work involves investigations into real-time automatic number-plate recognition and its extension to other aspects of road traffic monitoring and control.
Severe Oleander Poisoning Presenting with Hyperkalaemia and Unusual Electrocardiographic Changes

Background Hyperkalaemia in oleander (Nerium oleander) poisoning has been associated with a poor prognosis. Different electrocardiographic (ECG) presentations are possible because of vagotonia and hyperkalaemia. Methods/Results We report a series of three cases of oleander poisoning in which ECG showed unusual hyperkalaemia features, such as bradyarrhythmia, sinoatrial block, atrioventricular block and junctional rhythm. Conclusions If arterial blood gas analysis or laboratory values indicate hyperkalaemia in oleander poisoning, the hyperkalaemia should be treated immediately, even if the ECG does not show typical hyperkalaemia features. LEARNING POINTS Hyperkalaemia in oleander poisoning is associated with a poor prognosis. Hyperkalaemia should be treated aggressively in oleander poisoning even if the ECG does not show typical features, as mimics other conditions on ECG.
Large-scale laboratory observations of wave forces on a highway bridge superstructure

The experimental setup and data are presented for a laboratory experiment conducted to examine realistic wave forcing on a highway bridge superstructure. The experiments measure wave conditions along with the resulting forces, pressures, and structural response of a 1:5 scale, reinforced concrete model of a typical section of the I-10 Bridge over Escambia Bay, Florida that failed during Hurricane Ivan in 2004. A unique feature of this model is its roller and rail system which allowed the specimen to move freely along the axis of wave propagation to simulate the dynamic response of the structure. The data are analyzed to study the relative importance of the impulse load versus the sustained wave load, the magnitudes of the horizontal to vertical forces, and their time histories to identify the modes of failure. The thesis examines the relationship between measured forces and wave momentum flux. The measured forces are also compared to recently published AASHTO guidelines. The author evaluates the distribution of forces under random wave conditions and proposes a method that calculates design loads based on exceedance probabilities.
Automatic risk adjustment for profit maximization in renewable dominated
 short‐term
 electricity markets

State-of-the-art trading strategies in short-term electricity markets employ risk awareness for reducing, inter alia, their exposure to the volatility of electricity prices. To ensure an optimal balance between risk and proﬁt, risk-aversion parameters are traditionally ﬁne-tuned via an oﬄine out-of-sample analysis. Such a computationally-intensive analysis is typically run once, which yields time-invariant risk policies. Instead, this paper proposes the use of machine learning to select, in an online fashion, optimal risk-aversion parameters. This novel automatic risk-tuning approach oﬀers the beneﬁt of continuously adjusting the risk policy based on the dynamically changing market operating conditions. Our approach is tested on two risk-aversion parameters, i.e., the conﬁdence level of the conditional value-at-risk and the budget of uncertainty, respectively considering scenario-based and robust optimization frameworks. A set of performed case studies – focusing on the very short-term dispatch of a market actor participating in electricity markets – using real-world market data from the Belgian power system demonstrate the ability of the proposed methodology to outperform traditional oﬄine risk policies.
Scanning transmission X-ray microscopy study of subcellular granules in human platelets at the carbon K- and calcium L2,3-edges

Abstract Platelets and their subcellular components (e.g., dense granules) are essential components in hemostasis. Understanding their chemical heterogeneities at the sub-micrometer scale, particularly their activation during hemostasis and production of platelet-derived extracellular vesicles, may provide important insights into their mechanisms; however, this has rarely been investigated, mainly owing to the lack of appropriate chemical characterization tools at nanometer scale. Here, the use of scanning transmission X-ray microscopy (STXM) combined with X-ray absorption near edge structure (XANES) to characterize human platelets and their subcellular components at the carbon K-edge and calcium L2,3-edge, is reported. STXM images can identify not only the spatial distribution of subcellular components in human platelets, such as dense granules (DGs) with sizes of ~200 nm, but also their granule-to-granule chemical heterogeneities on the sub-micrometer scale, based on their XANES spectra. The calcium distribution map as well as the principal component analysis of the STXM image stacks clearly identified the numbers and locations of the calcium-rich DGs within human platelets. Deconvolution of the carbon K-edge XANES spectra, extracted from various locations in the platelets, showed that amide carbonyl and carboxylic acid functional groups were mainly found in the cytoplasm, while ketone-phenol-nitrile-imine, aliphatic, and carbonate functional groups were dominant in the platelet DGs. These observations suggest that platelet DGs are most likely composed of calcium polyphosphate associated with adenosine triphosphate (ATP) and adenosine diphosphate (ADP), with significant granule-to-granule variations in their compositions, while the cytoplasm regions of platelets contain significant amounts of proteins.
Towards Sustainable Finance: Conceptualizing Future Generations as Stakeholders

The paper aims to address a difficult yet important issue of the modern world, which is related to a lack of consideration, from investors’ point of view, for the sustainable future of our socioeconomic system. Many investors think in terms of MSV (maximization of the shareholder value) and fail to consider other important stakeholders. Future generations will “inherit” the results of the actions of current generations. Investing money in some lucrative ideas is definitely a very important financial activity, but it must be done responsibly. The Sustainable Development Goals (SDGs) postulated by the UN; the Environmental, Social, and Governance (ESG) criteria; and the Equator Principles are some notions proposed to be considered to make investors’ actions more responsible. Future generations deserve a better, safer, and unwasted place to live in, so it is the right time to start thinking of them as major stakeholders. The paper reviews some of the important research related to this issue and brings its contribution to the stakeholder theory by proposing a new vision, one that is future oriented. The proposal to conceptualize future generations as stakeholders is an important contribution of the paper. Methodologically, we relied on relevant literature and recent initiatives and approaches. Further research is needed to identify the means to operationalize our proposal.
The Rise of Casual Work in Nigeria: Who Loses, Who Benefits?

The use of casual labour has been a source of ongoing conflict between workers, labour unions, and employers in most organizations in Nigeria. Many scholars and commentators have written and spoken extensively on the subject matter, yet in most cases their approach tended to be one-sided, skewed and lack duality of purpose. Attempt to look at it from another angle or juxtapose its position is rare and almost absent. Therefore, this paper through content analysis of literature review examined the rise of casual work in Nigeria vis-a-vis its challenges and benefits to Nigerians. It anchored casual work in Nigeria on Neo-liberal and Equity theories. The paper opined that casual work is not in all cases bad as most people think. It has its benefits and in some cases, it is a matter of choice. Also, the paper is
In-line optical phase-sensitive amplifier with pump light source controlled by optical phase-lock loop

This paper describes an in-line optical phase-sensitive amplifier (PSA) with a pump laser whose optical phase is locked to that of a randomly modulated signal by using an optical phase-lock loop (OPLL). The OPLL is designed with the capability of optical phase locking at an arbitrary relative phase. Experimental evaluation is presented of the OPLL employing a newly developed external cavity semiconductor ring laser with a spectrum linewidth of less than 20 kHz. Employing this pump laser with the OPLL in conjunction with a 4.4-km long nonlinear fiber Sagnac interferometer (NFSI) yields optical phase-sensitive gain of up to 11 dB. A randomly modulated signal is successfully amplified and confirmed offering a clear eye-opening.
THE INJECTION LINE AND CENTRAL REGION DESIGN OF CYCIAE-70*

A 70MeV compact cyclotron is under design at CIAE, which is aimed to provide both proton and deuteron by stripping two electrons from H – beam and D – beam respectively. Both of the negative charged beams are produced in a single external multi-cusp ion source, injected axially by a low energy beam injection line and bent onto the median plane through a spiral inflector. In the central region, the electrode structures and the shape of Dee tips are constructed and optimized to achieve matching at the inflector exit and to maximize the acceptance of the central region. The preliminary design results of the injection line, the spiral inflector and the central region are elaborated in the paper.
Exploring the Praxis of Occupational Therapy-Community Development Practitioners

Background. A growing body of occupational therapy knowledge and practice focuses not on health but on social transformation, and couples occupational therapy with community development. A tension in both these fields is the disconnect between what practitioners espouse and what they do, limiting the potential of practice. To address this, practitioners are encouraged to engage in praxis—the critical synthesis of theory and practice. Purpose. To explore whether and how Australian occupational therapy-community development practitioners engage in critical praxis. Method. A critical dialogical method was employed to complete multiple in-depth interviews with four occupational therapy-community development practitioners. Interviews were transcribed and analyzed using thematic analysis. Findings. Practitioners appeared capable of praxis but were not consistently employing it. Findings were grouped into themes: disjointed praxis, authentic praxis, supporting praxis, and praxis challenges and solutions. Implications. Occupational therapists need to be supported to develop, use, and maintain skills in critical praxis.
Image quality with narrow beam illumination in an active tracking system

The estimation of the angular position of an object and the evaluation of image quality are considered for an active tracking system consisting of an agile scanning transmitter and an imaging receiver. In many applications (e.g. imaging at long ranges) transmitter energy/pulse requirements are stressing, and flood illumination of targets will result in images that are severely degraded due to photon shot noise. In order to achieve better image quality and tracking accuracy, it may be preferable to scan a narrow beam over the entire object or an object feature. This may reduce the effects of shot noise, but would magnify the effects of beam jitter. In this paper, we examine the effects of these two sources of image degradation, and introduce various measures of image quality. The quality of the restoration of the degraded image is evaluated, showing the extent to which the effects of beam jitter and shot noise can be reduced. There exists an optimum beam size for which the quality of the restored image is best. The sensitivity of image quality to the selection of beam size is examined, and the effect of narrow beam illumination on the performance of various algorithms is discussed.

This paper presents the design considerations and the implementation of a cd-cd buck-boost converte, which can process the energy transferred from the ultra capacitors (UC) bank and batteries to the load (motor drive system of an Electric Vehicle EV). The UC bank is used as auxiliary source to supply the motor drive system which allows recovering the energy generated during the regenerative breaking; the above mentioned energy is used to start the EV. Also, the analysis and design of a non-linear type controller, used in this application, are presented simulation.
Great expectations for offshore wind turbines: Emulation of wind farm design to anticipate their value for customers

To date, the technical feasibility of making electricity from offshore wind energy has been convincingly proven. However, the current challenge is to reduce the costs of this form of energy. One of the aspects playing a role in cost reduction is the optimisation of the wind turbine. The wind turbine influences the costs of various elements of an offshore wind farm, such as the structure on which it will be built, the electrical cabling, the installation, maintenance and, last but not least, the electricity production. The extent of this influence is hard to determine during the design of the wind turbine. In this research a method is developed to assess the effects of a wind turbine on the costs and performance of an offshore wind farm. Core of the method is a software program that automatically designs a wind farm for a turbine for which the user provides the inputs. By varying the inputs, the user can find the turbine design for which the cost of energy would be lowest. The method has been tested with a case study and with industrial users. The case study shows that the method can indeed lead to a better wind turbine design and the test-users confirm the utility of the program. Using the program stimulates further cooperation between the marketing and engineering departments, which may require a different way of working for some companies. The thesis provides a more extensive summary.
A Review of 3-Nitrooxypropanol for Enteric Methane Mitigation from Ruminant Livestock

Simple Summary Enteric methane (CH4) from the anaerobic fermentation of feed carbohydrates in ruminant livestock accounts for 3 to 5% of global greenhouse gas emissions. Among the different CH4 mitigating approaches evaluated to decrease enteric CH4 emissions from ruminants, the feed additive 3-nitrooxypropanol is effective with a mean reduction in CH4 of 30%, depending on animal type, diet and dose. 3-nitrooxypropanol is chemically synthesized and studies show low safety risk with no detrimental effects to animals and humans. 3-nitrooxypropanol was recently approved by regulatory authorities for use in Brazil and Chile and has received a favorable opinion from the scientific panel of the European Food Safety Authority, with approvals in various jurisdictions expected in the near future. As a substantial body of research on 3-nitrooxypropanol is now available, this review offers a timely analysis of the opportunities and challenges of using 3-nitrooxypropanol to mitigate enteric CH4 emissions in ruminant livestock. Abstract Methane (CH4) from enteric fermentation accounts for 3 to 5% of global anthropogenic greenhouse gas emissions, which contribute to climate change. Cost-effective strategies are needed to reduce feed energy losses as enteric CH4 while improving ruminant production efficiency. Mitigation strategies need to be environmentally friendly, easily adopted by producers and accepted by consumers. However, few sustainable CH4 mitigation approaches are available. Recent studies show that the chemically synthesized CH4 inhibitor 3-nitrooxypropanol is one of the most effective approaches for enteric CH4 abatement. 3-nitrooxypropanol specifically targets the methyl-coenzyme M reductase and inhibits the final catalytic step in methanogenesis in rumen archaea. Providing 3-nitrooxypropanol to dairy and beef cattle in research studies has consistently decreased enteric CH4 production by 30% on average, with reductions as high as 82% in some cases. Efficacy is positively related to 3-NOP dose and negatively affected by neutral detergent fiber concentration of the diet, with greater responses in dairy compared with beef cattle when compared at the same dose. This review collates the current literature on 3-nitrooxypropanol and examines the overall findings of meta-analyses and individual studies to provide a synthesis of science-based information on the use of 3-nitrooxypropanol for CH4 abatement. The intent is to help guide commercial adoption at the farm level in the future. There is a significant body of peer-reviewed scientific literature to indicate that 3-nitrooxypropanol is effective and safe when incorporated into total mixed rations, but further research is required to fully understand the long-term effects and the interactions with other CH4 mitigating compounds.
Global Hotspots and Prospects of I-131 Therapy in Thyroid Carcinoma via Bibliometric Analysis

Background Hundreds of studies have reported the application of iodine-131 (I-131) in thyroid carcinoma (THCA) in past years. However, the status of research in the field and other related topics have not been investigated. This study aimed to identify the cooperation of authors, countries, and institutions, as well as explore the hot topics and prospects regarding I-131 therapy in THCA based on previous studies. Methods Publications from 2010 to 2020 were retrieved from Web of Science Core Collection according to research strategy. Bibliometric analyses were performed using VOSviewer 1.6. 15 and CiteSpace 5.7. 3 to evaluate and visualize the cooperation network, hot topic, and research frontier. Results The number of publications showed a trend of fluctuation between 2010 and 2020. We identified 1387 publications related to I-131 therapy in THCA, which were published by 1628 institutions from 82 countries. The largest proportion of publications were emanated from the USA, and the majority of papers were published by Thyroid. Shanghai Jiao Tong University of China contributed the most papers. Although many authors participated in the research of this field, high-yield authors were few. Co-occurrence analysis classified keywords into five clusters, including assessment, efficacy measurement, monitoring, hormone regulation, and guidelines of I-131 therapy. The terms “bone marrow dosimetry and time” were among the latest hotspots. The research frontier topic in I-131 therapy focused on the “P53 and anti-Müllerian hormone”. Conclusion The attention to I-131 therapy in THCA should be increased considerably. It was necessary to construct active co-operations between authors, countries, and institutions to promote the development of this field. Recent researches referred to the timing and dose assessment of I-131 therapy in THCA. Future studies likely focused on targeted therapy and adverse effects evaluation were worthy of research as well.
The influence of some construction parameters on electric stress grading in XLPE cable terminations

A finite element method (FEM) based analysis was performed in order to design different constructions of terminations for crosslinked polyethylene (XLPE) cables. The primary task was to limit the electric field at the insulation screen end of XLPE cables. Numerical modeling made it possible to monitor how stress relief cones and materials with different relative dielectric constant alone or in a combination with isolated or grounded embedded electrodes (EE) affected the electric stress grading. The most promising constructions of the cable terminations were selected for experimental testing in a high voltage laboratory.
At-wavelength optics characterization metrology at Shanghai Synchrotron Radiation Facility

In recent years, X-ray phase sensing technology has been widely used in at-wavelength metrology and optical characterization. One of the latest developments is the technology based on X-ray speckle. It has attracted wide attention because of its simple and flexible experimental arrangement, high-cost performance, multi-mode, and high angular sensitivity. The speckle-based technique can precisely measure the wavefront and associated aberrations and is therefore a suitable device for in-situ metrology. Shanghai Synchrotron Radiation Facility (SSRF) has been implemented and further improved such a technique. We have demonstrated that the speckle-based technique can be used in the wavefront measurement of the reflective and transmissive optics and diffraction optics such as mirrors, lens, and crystals. This paper will introduce the latest developments in speckle-based wavelength measurement technology and some application examples at SSRF.
