Evaluation results of power supply to ICT equipment using HVDC distribution system (2010)

In recent years, Higher Voltage Direct Current (HVDC) distribution systems have been proposed to reduce power consumption in telecommunication buildings and data centers. NTT FACILITIES and NTT Data conducted verification tests of a HVDC distribution system at a Tokyo data center from January 29 to October 30, 2009. This paper summarizes the results of studies on HVDC distribution systems obtained so far, describes verification tests based on those results, and examines the test results. The verification tests were conducted with the cooperation of domestic and international ICT equipment vendors. We measured the energy savings and stability of the power supply involved long-term powering of ICT equipments (servers and storages) with an HVDC system. The test results show the superiority of the HVDC distribution system over the existing AC system. These test results also validate the HVDC system specifications proposed by the NTT group for standardization. These results may develop the current vigorous discussion of international standardization for HVDC distribution systems.
The SINFET&#8212;A Schottky injection MOS-gated power transistor (1986)

A new MOS-gated power device, the Schottky injection FET (SINFET), is described in this paper. The device offers 6 times higher current handling capability than conventional n-channel power LDMOS transistors of comparable size and voltage capability and still maintains a comparable switching speed. The low on-resistance is obtained by conductivity modulation of the high-resistivity n- drift region using a Schottky injector. Since only a small number of minority carriers are injected, the speed of the device is not degraded substantially and high latchup resistance is achieved. Breakdown voltages and specific on-resistance observed on typical devices are 170 V and 0.01 Ω . cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , respectively. Gate-turn off times are of the order of 30 ns. Two-dimensional simulation and experimental results comparing the SIN-FET with the LDMOST and lateral insulated gate transistor (LIGT) are presented.
Query Generation for Resolving Ambiguity in User's Command for a Mobile Service Robot (2019)

This paper describes a method of generating queries for resolving ambiguities in the user's command in service robotics applications. We deal with bring-me tasks, in which a robot brings a user-specified object from a distant place. A user's command may be ambiguous due to various reasons such as the uncertainty in his/her knowledge of the distant scene and the robot's knowledge. In such a case, the robot compares its recognition result with the command and generates a query for disambiguation. Based on previous VDQG (visual discriminative question generation) work, we develop a method for query generation using the concept of attribute contrast with the attribute categorization. We verified our method by comparing the user and the generated queries. We also implemented a robotic system, as a proof-of-concept, that can interact with the user and certainly achieve bring-me tasks.
Redox proteomics identification of 4‐hydroxynonenal‐modified brain proteins in Alzheimer's disease: Role of lipid peroxidation in Alzheimer's disease pathogenesis (2009)

Numerous studies have shown that neuronal lipids are highly susceptible to oxidative stress including in those brain areas directly involved in the neurodegenerative process of Alzheimer's disease (AD). Lipid peroxidation directly damages membranes and also generates a number of secondary biologically active products (toxic aldehydes)that are capable of easily attacking lipids, proteins, and DNA. Accumulating evidence has demonstrated regionally increased brain lipid peroxidation in patients with AD; however, extensive studies on specific targets of lipid peroxidation-induced damage are still missing. The present study represents a further step in understanding the relationship between oxidative modification of protein and neuronal death associated with AD. We used a proteomics approach to determine specific targets of lipid peroxidation in AD brain, both in hippocampus and inferior parietal lobule, by coupling immunochemical detection of 4-hydroxynonenal-bound proteins with 2-D polyacrylamide gel electrophoresis and MS analysis. We identified 4-hydroxynonenal-bound proteins in the hippocampus and inferior parietal lobule brain regions of subjects with AD. The identified proteins play different biological functions including energy metabolism, antioxidant system, and structural proteins, thus impairing multiple molecular pathways. Our results provide further evidence for the role of lipid peroxidation in the pathogenesis of AD.
A novel coded excitation scheme to improve spatial and contrast resolution of quantitative ultrasound imaging (2009)

Quantitative ultrasound (QUS) imaging techniques based on ultrasonic backscatter have been used successfully to diagnose and monitor disease. A method for improving the contrast and axial resolution of QUS parametric images by using the resolution enhancement compression (REC) technique is proposed. Resolution enhancement compression is a coded excitation and pulse compression technique that enhances the -6-dB bandwidth of an ultrasonic imaging system. The objective of this study was to combine REC with QUS (REC-QUS) and evaluate and compare improvements in scatterer diameter estimates obtained using the REC technique to conventional pulsing methods. Simulations and experimental measurements were conducted with a single-element transducer (f/4) having a center frequency of 10 MHz and a -6-dB bandwidth of 80%. Using REC, the -6-dB bandwidth was enhanced to 155%. Images for both simulation and experimental measurements contained a signal-to-noise ratio of 28 dB. In simulations, to monitor the improvements in contrast a software phantom with a cylindrical lesion was evaluated. In experimental measurements, tissue-mimicking phantoms that contained glass spheres with different scatterer diameters were evaluated. Estimates of average scatterer diameter in the simulations and experiments were obtained by comparing the normalized backscattered power spectra to theory over the -6-dB bandwidth for both conventional pulsing and REC. Improvements in REC-QUS over conventional QUS were quantified through estimate bias and standard deviation, contrast-to-noise ratio, and histogram analysis of QUS parametric images. Overall, a 51% increase in contrast and a 60% decrease in the standard deviation of average scatterer diameter estimates were obtained during simulations, while a reduction of 34% to 71% was obtained in the standard deviation of average scatterer diameter for the experimental results.
GNSS Spoof Detection Using Passive Ranging (2016)

Advances in electronics technology have enabled the creation of malicious RF interference of GNSS signals. For example jamming completely denies the GNSS user of position, navigation, and time (PNT) information. While a serious concern when we expect PNT at all times, current generation GNSS receivers often warn the user when PNT is unavailable. A second threat to GNSS integrity is spoofing, the creation of counterfeit GNSS signals with the potential to confuse the receiver into providing incorrect PNT information. This type of attack is considered more dangerous than a jamming attack since erroneous PNT is often worse than no solution at all. A variety of approaches have been proposed in the literature to recognize spoofing and can vary widely based upon the assumed capabilities and a priori knowledge of the spoofer. One method is to compare the GNSS result to data from a non-GNSS sensor. At the January 2016 ION ITM these authors developed and analyzed a spoof detection algorithm based upon measurements from an active ranging system (distances, but no heading). This paper expands the class of signals viable for this spoofing detection approach to passive ranging; equivalently, to range measurements which depend upon knowledge of precise time (effectively pseudoranges).
Wilms Tumor Locus on 11p13 Defined by Multiple CpG Island-Associated Transcripts (1990)

Wilms tumor is an embryonal kidney tumor involving complex pathology and genetics. The Wilms tumor locus on chromosome 11p13 is defined by the region of overlap of constitutional and tumor-associated deletions. Chromosome walking and yeast artificial chromosome (YAC) cloning were used to clone and map 850 kilobases of DNA. Nine CpG islands, constituting a "CpG island archipelago," were identified, including three islands that were not apparent by conventional pulsed-field mapping, and thus were at least partially methylated. Three distinct transcriptional units were found closely associated with a CpG island within the boundaries of a homozygous DNA deletion in a Wilms tumor.
The right to refuse medical treatment. (1983)

It is becoming an increasingly frequent occurrence for the emergency nurse to encounter patients and families who question treatment offered in the emergency department and who even refuse treatment. In general, a competent, conscious adult has the right to refuse medical treatment. The key to handling the patient who refuses treatment in the emergency department is careful assessment of the patient and the apparent reason for his refusal of treatment. The emergency nurse who is confronted with a patient who refuses care must initially ask whether the patient is mentally competent to refuse treatment. Is the patient’s ability to reason impaired by drugs or alcohol? Does the patient show signs of organic mental impairment? Patients who are disoriented, confused, or unable to comprehend this condition should not be permitted to leave the emergency department. It is appropriate to use reasonable restraints when necessary to maintain the patient in the emergency department, pending further medical evaluation of his condition. Documentation of the patient’s physical and mental status should be carefully noted on the ED record, as well as careful notation of the need for any reasonable restraints. If the patient who insists on leaving without treatment appears to be in control of his mental processes, the ED staff has a duty to warn the patient
Agent neutralization studies III. Detoxification of VX in aqueous persulfate. Final report, May-August 1993 (1994)

Aqueous solutions of persulfate salts are frequently used to mineralize organic substrates in the course of total organic carbon analyses. A study has been conducted at the U.S. Army Edgewood Research, Development and Engineering Center to determine whether this approach may be useful to neutralize the nerve agent VX. VX was reacted with aqueous ammonium persulfate at 90 deg C and 70 deg C. The concentration of agent and the acidity of the mixture were varied. 31P-NMR was used to monitor the destruction of VX as well as the formation and degradation of the phosphorus-containing products. A titration procedure using ferrous sulfate and ceric ammonium nitrate was used to monitor the consumption of persulfate. The products formed and their stabilities were found to vary significantly with the acidity of the solution.

ChemCalc: A Building Block for Tomorrow’s Chemical Infrastructure (2013)

Web services, as an aspect of cloud computing, are becoming an important part of the general IT infrastructure, and scientific computing is no exception to this trend. We propose a simple approach to develop chemical Web services, through which servers could expose the essential data manipulation functionality that students and researchers need for chemical calculations. These services return their results as JSON (JavaScript Object Notation) objects, which facilitates their use for Web applications. The ChemCalc project http://www.chemcalc.org demonstrates this approach: we present three Web services related with mass spectrometry, namely isotopic distribution simulation, peptide fragmentation simulation, and molecular formula determination. We also developed a complete Web application based on these three Web services, taking advantage of modern HTML5 and JavaScript libraries (ChemDoodle and jQuery).
Beware of Scorecards (2010)

Scorecards are presented as reliable measures of medical outcomes. They are used as a means for measuring the quality of care provided and as a tool for negotiating fees for medical services. The existence of scorecards reflects our society's desire for openness and transparency in public affairs. The problem with scorecards and other publicly accessible ratings is that some of the recommendations they issue do not warrant the reliance of the public. In other words, scorecards that present ratings of medical professionals and medical institutions may themselves be untrustworthy. Scorecards are designed to encourage physicians to achieve "target rates" for health care interventions. Scorecards have been touted as a mechanism to improve patient care, advance patient decision making, and hopefully improve health outcomes. We need to be aware of how ratings of physician performance may affect your physician's clinical judgment, recommendations, and communication.
Optical Pulse Propagation via Whispering Gallery Modes in Glass Spheres (1998)

Early in this century, Rayleigh 1 showed that waves could propagate close to the wall of a spherical cavity with very little loss as long as the wavelength was small compared to the cavity circumference. The treatment was primarily for acoustic waves, modeling the whispering gallery effect, but he pointed out that electromagnetic waves should behave similarly. Study of the optical properties of dielectric spheres has received new interest with improvements in optical instrumentation and the emergence of new applications for high-Q resonators. It has recently been shown that optical pulses propagating in whispering gallery modes can be treated analogously to pulses in a fiber optic waveguide. Since the optical fields extend beyond the surface of the sphere, the sphere's environment could alter propagation properties such as cavity ringdown time. We describe here some time and frequency-domain measurements of picosecond pulses in glass spheres of millimeter dimension and discuss potential analytical applications.
Economic impacts of advanced weather forecasting on energy system operations (2010)

We analyze the impacts of adopting advanced weather forecasting systems at different levels of the decision-making hierarchy of the power grid. Using case studies, we show that state-of-the-art numerical weather prediction (NWP) models can provide high-precision forecasts and uncertainty information that can significantly enhance the performance of planning, scheduling, energy management, and feedback control systems. In addition, we assess the forecasting capabilities of the Weather Research and Forecast (WRF) model in several application domains.

Gas sensors in a dynamic operation mode (2008)

Temperature-modulated metal-oxide gas sensors exhibit different behavior from sensors operating in an isothermal mode. Such temperature-modulated sensor response is affected by stimulating excitation, sensor structure, sensitive layer preparation etc. Due to different reaction rates dependent on modulating temperature, the response yields a special signature for the investigated gas atmosphere. The response can be analyzed using different pattern recognition and artificial intelligence methods. As a result, one can achieve an improvement of selectivity and drift reduction. It is also possible to accomplish a qualitative and quantitative analysis of gas mixtures using a single sensor. One of the most important issues is the selection of proper parameters of a signal that modulates the heater temperature. The range of temperature variations should be chosen according to the gas type and its concentration to achieve good sensitivity. The period of the excitation signal also influences the sensor response and has to be chosen above the value of gas/semiconductor reaction time constant. In this paper the authors describe the ways in which a temperature-modulating signal is selected and discuss the possibility of using a dynamic sensor response to quantitatively determine the concentrations of two gases in a mixture with the help of one sensor.

Imaging the Sublimation Dynamics of Colloidal Crystallites (2006)

We studied the kinetics of sublimating crystals with single-particle resolution by experiments with colloidal spheres and by computer simulations. A short-range attraction between spheres led to crystallites one to three layers thick. The spheres were tracked with optical microscopy while the attraction was reduced and the crystals sublimated. Large crystallites sublimated by escape of particles from the perimeter. The rate of shrinkage was greatly enhanced, however, when the size decreased to less than 20 to 50 particles, depending on the location in the phase diagram. At this size, the crystallites transformed into a dense amorphous structure, which rapidly vaporized. The enhancement of kinetics by metastable or unstable phases may play a major role in the melting, freezing, and annealing of crystals.
Reliable Identification Schemes for Asset and Production Tracking in Industry 4.0 (2020)

Revolutionizing logistics and supply chain management in smart manufacturing is one of the main goals of the Industry 4.0 movement. Emerging technologies such as autonomous vehicles, Cyber-Physical Systems and digital twins enable highly automated and optimized solutions in these fields to achieve full traceability of individual products. Tracking various assets within shop-floors and the warehouse is a focal point of asset management; its aim is to enhance the efficiency of logistical tasks. Global players implement their own solutions based on the state of the art technologies. Small and medium companies, however, are still skeptic toward identification based tracking methods, because of the lack of low-cost and reliable solutions. This paper presents a novel, working, reliable, low-cost, scalable solution for asset tracking, supporting global asset management for Industry4.0. The solution uses high accuracy indoor positioning-based on Ultra-Wideband (UWB) radio technology-combined with RFID-based tracking features. Identifying assets is one of the most challenging parts of this work, so this paper focuses on how different identification approaches can be combined to facilitate an efficient and reliable identification scheme.
Adaptive Parallel Graph Mining for CMP Architectures (2006)

Mining graph data is an increasingly popular challenge, which has practical applications in many areas, including molecular substructure discovery, Web link analysis, fraud detection, and social network analysis. The problem statement is to enumerate all subgraphs occurring in at least sigma graphs of a database, where sigma is a user specified parameter. Chip multiprocessors (CMPs) provide true parallel processing, and are expected to become the de facto standard for commodity computing. In this work, building on the state-of-the-art, we propose an efficient approach to parallelize such algorithms for CMPs. We show that an algorithm which adapts its behavior based on the runtime state of the system can improve system utilization and lower execution times. Most notably, we incorporate dynamic state management to allow memory consumption to vary based on availability. We evaluate our techniques on current day shared memory systems (SMPs) and expect similar performance for CMPs. We demonstrate excellent speedup, 27-fold on 32 processors for several real world datasets. Additionally, we show our dynamic techniques afford this scalability while consuming up to 35% less memory than static techniques.
The therapeutic reactivation of fetal haemoglobin (1998)

Unusually high levels of fetal haemoglobin production can ameliorate sickle cell disease and beta thalassaemia. Although efforts directed at the pharmacological stimulation of fetal haemoglobin as an approach to managing these conditions have met with limited success, there is wide variation in individual responses. Whether this reflects the particular mutations that underlie these conditions or other genetic factors remains to be determined, as does the ideal combination of agents to achieve this end. These results are encouraging, however, in particular in view of the recent demonstration that other monogenic diseases, Duchenne muscular dystrophy, for example, might be amenable to the same therapeutic strategy.
