Molecular genetic blood group typing by the use of PCR‐SSP technique (2007)

PCR-SSP is a helpful supplementary technique for resolving most of the common problems caused by discrepant or doubtful serologic results, and it is an easy-to-handle robust method. Questionable cases in donor, recipient, and patient typing can be examined with acceptable cost.
Ability of Neisseria gonorrhoeae, Neisseria meningitidis, and commensal Neisseria species to obtain iron from transferrin and iron compounds (1981)

The ability of Neisseria species to use iron compounds and to compete with iron-binding proteins was examined with deferrated defined medium and the iron chelator deferoxamine. All Neisseria species were able to assimilate a variety of ferric and ferrous iron salts. They were not able to efficiently solubilize an inorganic iron salt such as ferric nitrate, but were able to use iron chelated by citrate, oxalacetate, pyrophosphate, or nitrilotriacetate. Each of the 95 Neisseria isolates examined was able to use hemin as a sole source of iron, and most, but not all, of the isolates were able to obtain iron from hemoglobin. Heated human serum stimulated growth of all gonococci, meningococci, and some commensal Neisseria species in iron-deficient medium. All gonococci and meningococci were able to scavenge iron from 25% saturated transferrin, whereas most commensal organisms were inhibited by this iron-binding protein. The ability to compete with transferrin was specific, since partially saturated conalbumin was bacteriostatic for all Neisseria species. Although the pathogenic Neisseria species were able to compete more efficiently with transferrin for iron than were the nonpathogenic Neisseria species, no correlation was observed between the virulence of different strains or colony types of gonococci and the ability to scavenge iron in vitro from transferrin or other chelators.
Highly Active Nitrogen-Doped Carbon Nanotubes for Oxygen Reduction Reaction in Fuel Cell Applications (2009)

One of the main challenges in the commercialization of low temperature fuel cells is the slow oxygen reduction reaction (ORR) kinetics and the high cost and scarcity of platinum (Pt)-based catalysts. As a result, alternative non-noble electrocatalysts to Pt materials for ORR is needed to realize the practical application of fuel cells. In this study, nitrogen-doped carbon nanotubes (NCNTs) were synthesized as a non-noble electrocatalyst for the ORR using ethylenediamine (EDA-NCNT) and pyridine (Py-NCNT) as different nitrogen precursors by a single-step chemical vapor deposition (CVD) process. The resulting EDA-NCNT has shown similar ORR performance compared to platinum on carbon support in terms of onset and half-wave potentials. Moreover, EDA-NCNT showed superior ORR performance in terms of limiting current density, number of electrons transferred, and H2O selectivity. The effects of nitrogen content on ORR performance of NCNT were investigated by comparing EDA-NCNT with Py-NCNT. The ORR performance of Py-NCNT was inferior compared to EDA-NCNT in terms of onset and half-wave potentials, limiting current density, number of electrons transferred, and H2O selectivity. Further material characterizations by X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy illustrated a higher nitrogen content and more defects in EDA-NCNT compared to that of Py-NCNT which indicates the important role of the nitrogen precursor on nitrogen content and structure of NCNT. By combining the results of ORR activity and material characterization, it is concluded that higher nitrogen content and more defects of NCNT lead to high ORR performance.
Saturn satellite encounter opportunities for Mariner Jupiter-Saturn 1977. (1973)

The opportunities for close satellite encounters which meet the planetary constraints at Saturn that are imposed by science value return and environmental conditions are investigated. Since the satellites travel at various speeds in their orbits, Saturn arrival time is critical and was chosen as the design parameter. Arrival times are recommended which afford close satellite encounters and also meet important mission constraints. A design chart illustrates the satellite opportunities as a function of Saturn arrival date. Through the use of such a design chart, the Saturn encounter design process, which will take place according to recommendations by the selected science investigators over the next several years, will be considerably streamlined. Potential applications are given to illustrate the use of the Saturn satellite opportunity chart in encounter design.
IN-VEHICLE MULTIMEDIA PLATFORM BASED ON DARMA (DUAL OS APPROACH) (2000)

This paper describes a next-generation in-vehicle multimedia platform, which operates highly reliable software and open software concurrently, but independently using DARMA technology. DARMA (Dependable Autonomous hard Real-time MAnagement) allows two operating systems, which are open OS for multimedia and telematics applications and RTOS (Real-time OS) for mission-critical software, to be run on one processor. The software firewall isolates mission-critical software from open application software, and auto-restart is available if one OS crashes. For the covering abstract see ITRD E114174.
Propelling efficiency of front-crawl swimming (1988)

In this study the propelling efficiency (ep) of front-crawl swimming, by use of the arms only, was calculated in four subjects. This is the ratio of the power used to overcome drag (Pd) to the total mechanical power (Po) produced including power wasted in changing the kinetic energy of masses of water (Pk). By the use of an extended version of the system to measure active drag (MAD system), Pd was measured directly. Simultaneous measurement of O2 uptake (VO2) enabled the establishment of the relationship between the rate of the energy expenditure (PVO2) and Po (since when swimming on the MAD system Po = Pd). These individual relationships describing the mechanical efficiency (8-12%) were then used to estimate Po in free swimming from measurements of VO2. Because Pd was directly measured at each velocity studied by use of the MAD system, ep could be calculated according to the equation ep = Pd/(Pd + Pk) = Pd/Po. For the four top class swimmers studied, ep was found to range from 46 to 77%. Total efficiency, defined as the product of mechanical and propelling efficiency, ranged from 5 to 8%.
Fundamental-Frequency Reactive Circulating Current Injection for Capacitor Voltage Balancing in Hybrid-MMC HVDC Systems During Riding Through PTG Faults (2017)

This paper presents a comprehensive analysis and a novel solution for the discharge problem on the half-bridge submodules' (HBSMs') capacitors in the hybrid modular multilevel converter (MMC)-based high-voltage direct current transmission systems under a long-term (e.g., several minutes or longer) pole-to-ground fault condition. The mechanism of this issue is analyzed, and then a solution based on fundamental-frequency reactive circulating current (FFRCC) injection is proposed. The influence of FFRCC injection is analyzed in terms of the fluctuated arm capacitor energy and the current stress of semiconductors. Moreover, an enhanced arm voltage modulation method based on HBSMs and full-bridge submodules coordinate control is proposed to accelerate the capacitor voltage balance of HBSMs. Finally, the performance of the proposed control strategy is verified by the simulation results.

Social relevance of topological communities in ad hoc communication networks (2011)

In this article, we investigate the social relevance of dynamic community structures that can be determined on dynamic communication networks. We first present and validate SAND/SHARC (Stability And Network Dynamics over Sharper Heuristic for Assignment of Robust Communities), a distributed algorithm for community detection. Then, based on real-world communication traces and social information, we evaluate how the structures found by SAND/SHARC can be translated to social links and favor interaction between users with similar social characteristics. Such a study is important to envision community detection algorithm in the design of ubiquitous social interaction protocols, like those used in mobile social networks (MoSoNets).

Analysis of Endothelial Barrier Function In Vitro (2011)

Increased microvascular solute permeability underlies many forms of pathophysiological conditions, including inflammation. Endothelial monolayer cultures provide an excellent model system which allows systemic and mechanistic study of endothelial barrier function and paracellular permeability in vitro. The endothelial-specific complexus adherens junction protein VE-cadherin and their intracellular complex form pericellular structures along the cell borders which are critical to regulate endothelial barrier function by controlling pericellular permeability of vasculature. Here, we describe methods for both visualizing and quantifying junctional permeability and barrier changes in endothelial monolayers in vitro.
Synthesis, Helical Organization, and Fibrous Formation of <i>C</i><sub>3</sub> Symmetric Methoxy-Substituted Discotic Hexa-<i>peri</i>-hexabenzocoronene (2008)

A novel C3 symmetric discotic hexa-peri-hexabenzocoronene with three alternating dodecyl and methoxy substituents was synthesized. The compound revealed pronounced self-aggregation in solution. The solution processing onto a substrate resulted in the formation of long fibrous nanostructures. Additionally, a complex helical superstructure in the solid state was derived from X-ray scattering results.
Improvements in cancer staging with PET/CT: literature-based evidence as of September 2006. (2007)

PET/CT with 18F-FDG is increasingly being used for staging, restaging, and treatment monitoring for cancer patients. CT is still frequently used only for attenuation correction and lesion localization. However, increasing sales of high-end scanners that combine PET with 64-detector CT strongly suggest that the field is moving toward a comprehensive concept, whereby diagnostic CT studies during intravenous contrast material application are combined with the highest-quality PET studies. At many institutions, in-line PET/CT has replaced separately acquired PET and CT examinations for many oncologic indications. This replacement has occurred despite the fact that only a relatively small number of well-designed prospective studies have verified imaging findings against the gold standard of histopathologic tissue evaluation. However, a large number of studies have used acceptable reference standards, such as pathology, imaging, and other clinical follow-up findings, for validating PET/CT findings. From these data, we believe, has emerged reliable evidence in support of the notion that PET/CT offers diagnostic advantages over its individual components for the major cancers.
UWB MicroDoppler Radar for human Gait analysis, tracking more than one person, and vital sign detection of moving persons (2013)

Pulse Doppler radars using UWB technology are becoming very popular for their wide range of capabilities and applications. UWB waveforms are used for imaging in indoor environments, target localization and classification behind walls, and evaluating micro-Doppler signatures. UWB pulse Doppler radars provide range-time-frequency representation that provides both highly accurate range and micro-Doppler information. This representation is used for detailed human gait analysis, tracking more than one subject even behind walls, and respiration rate detection even for moving subjects. That can be very useful for remotely health monitoring. In this study we experimentally investigate applying UWB to tracking more than one human subject as well as detection of respiration rate of a moving person.
USE OF HIGH‐DOSE GADOLINIUM AS CONTRAST MEDIA TO AVOID RADIOCONTRAST MEDIA‐INDUCED NEPHROPATHY (2009)

Patients at risk for radiocontrast media-induced nephropathy (RCIN) with suspected peripheral vascular disease were evaluated with high-dose (0.4 mmol/kg) gadolinium-based (Gd) contrast angiography (AG). The patients who were considered susceptible to RCIN were defined by having one or more of the following: (1) pre-existing serum creatinine (SCr) >124 micromol/l, (2) diabetes mellitus and (3) age >60 years. An increase in SCr > or = 44 micromol/l or > or = 25% of baseline was considered significant. Ten patients underwent peripheral AG using a high dose of Gd without any adverse reaction. The mean age was 67.8 years. Nine (90%) patients were diabetic. The quality of these images was satisfactory for diagnosis in eight out of 10 patients. None of these patients had significant change in SCr. The mean SCr (+/-SD) before, at 48 hours and at 72 hours after AG were 182 +/- 97, 177 +/- 99 and 177 +/- 98 micromol/l, respectively. Based on this limited study, Gd is a promising agent for peripheral angiographic study. In patients at risk for RCIN, the high dose of Gd appears to be safe without obvious nephrotoxicity.
Determination of Prostate Volume by Transrectal Ultrasound (1991)

Estimation of prostate gland volume with transrectal ultrasound may provide important information in the evaluation of benign and malignant prostatic diseases. To determine the most accurate means of volume estimation 150 patients underwent transrectal ultrasound with 15 separate methods of volume estimation. All patients underwent subsequent radical prostatectomy or cystoprostatectomy. Prostate specimen weights were compared with the results of each volume estimation method. Step-section planimetry, previously assumed to be the most accurate means of volume measurement, exhibited a Pearson correlation coefficient of 0.93. The elliptical volume, widely used as an alternative to planimetry, demonstrated a correlation coefficient of 0.90. The most accurate method to estimate prostate weight (r = 0.94) was a variation of the prolate spheroid formula, expressed as pi/6 (transverse dimension)2 (anteroposterior dimension). When different volume ranges were considered, this prolate spheroid formula provided the closest estimate of weight in glands of less than 40 gm. and those in the 40 to 80 gm. range. The most accurate method to estimate prostates weighing greater than 80 gm. was the formula pi/6 (transverse dimension)3.
Efficient radiation from an electrically small antenna: control of higher order modes (2002)

The time domain Poynting theorem is used to develop a complex Poynting vector that is applicable to all electromagnetic radiation fields. We find that the traditional complex Poynting vector applies to fields generated by either solenoidal, TE, or irrotational, TM, sources but not both; most antennas generate one or the other. A direct result is that the commonly accepted proof that Q of electrically small antennas is large and increases precipitously with decreasing size breaks down with mixed TE and TM modes. A compound antenna generating mixed TE and TM modes is analyzed and it is determined that the input impedance is purely resistive and independent of the electrical size; Q increases with decreasing size but not as rapidly as previously believed to be required. There is reasonable hope of obtaining an electrically small, efficient radiator of electromagnetic radiation. Difficulties in the implementation of compound antennas include control of unwanted higher order modes and the large differences between the input impedances of TE and TM sources. The significance and control of higher order modes for TE and TM radiators are discussed.

The frequency resolution reaches 0.04GHz (@ 114GHz) and 2GHz (@ 1.78THz). The spectral line width (Δf) is preliminarily analyzed.
Single stepping in event-visualization tools (1996)

Event visualization tools are commonly used to facilitate the debugging of distributed applications. Although these tools provide a graphical view of distributed executions, they are frequently insufficient for full debugging purposes. The need for traditional debugging operations is often overlooked when building these tools. One of the most useful operations in traditional debuggers is single stepping. However, the difficulties faced when dealing with partially ordered-executions have deterred the development of a single-stepping method for concurrent processes. This paper describes a single-stepping operations suitable for eventvisualization tools. Three different methods for single stepping are presented: global-step, step-over and step-in. Abstraction techniques are commonly used to reduce the overwhelming amount of detail presented to the user. Accordingly, single stepping in the presence of abstraction is considered. The operations defined in this paper have been implemented in ...
1×8 micro-mechanical switches based on moving waveguides for optical fiber network switching (2002)

The feasibility of 1/spl times/N switches based on moving waveguides has been demonstrated. Solutions have been developed to overcome the technological hurdles encountered. The elementary 1/spl times/2 switch performances have been strongly improved: very low crosstalk (<-42 dB), low optical losses (1.5 dB), insensitivity to wavelength (<0.2 dB, 1250-1650 nm wavelength range) and polarisation (<0.3 dB), low driving voltage (<70 V), low switching time (<5 ms). Due to the results associated with a size reduction and a very accurate and reproducible control of residual deflection, we have demonstrated that the fabrication of larger 1/spl times/N switches is possible by cascading 1/spl times/2 switches. 1/spl times/8 switches have been fabricated. Moreover an 8/spl times/8 switching matrix has been demonstrated using arrays of 1/spl times/8 switches. These demonstrations show that this technology can address the different switching applications.
The Characterization of LiMn<sub>2</sub>O<sub>4</sub> Thin Film Cathode for Lithium Rechargeable Microbattery Prepared by Liquid Source Misted Chemical Deposition (2003)

Abstract Liquid source misted chemical deposition was used to fabricate LiMn 2 O 4 film as a cathode for lithium rechargeable microbatteries. The effect of crystallization temperature on the film properties was investigated by X‐ray diffraction (XRD), Raman spectroscopy (RS), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), cyclic voltammetry (CV), and charge/discharge experiments. When the heat treatment for crystallization of the as‐deposited film was carried out at 800 °C in a rapid thermal apparatus (RTA) in an oxygen atmosphere for 5 min, the structural and compositional purity, and the electrochemical activity of the deposited film, were optimized. The LiMn 2 O 4 films prepared by this method exhibited much better electrochemical rechargeability than those deposited by other techniques, such as sputtering, laser ablation, sol–gel coating, etc. The prepared film exhibits an initial discharge capacity of 62.5 μA h cm –2 μm –1 and a low capacity fade of 8.0 % over 100 cycles.

Thispaper focuses on audio-watermarking authentication and integrity-protection within the context of the speech-data transmitted over the Internet in a real-time learning environment.The Arabic Quran recitation through distance learning is used as a case-study example that is characteristic of sensitive data requiring robust authentication and integrity measures. Thisworkproposes an approach for the purpose ofauthenticating and validatingaudio-data transmitted by a publisher or during communications between an instructor and students reciting via Internet communications.The watermarking approach proposed here is based on detection of the key patternswithin the audio signal as an input to the algorithm before the embedding phase is performed.The developed application could be easily used at both sides of the communication for ensuring authenticity and integrity of the transmitted speech signal and is proved effective for many distance-learning applications that require low-complexity processing in real-time
Atlanta Fiber System Experiment: Practical 45-Mb/s Regenerator for Lightwave Transmission (1978)

A 45-Mb/s optical regenerator using an avalanche photodiode and a GaAlAs injection laser has been designed for a field environment. Its design and performance are described here. Feedback control of the optical transducers permits operation over a temperature range of 0 to 60° C. The regenerator has simple power requirements, and optical connectors permit easy installation. Its input sensitivity and output power makes useful regenerator spacings possible with currently available optical fiber. The large AGC range permits a wide range of regenerator spacings. A novel phase-locked loop design achieves a wide pull-in range for the timing recovery circuitry.
