Studies of Corrosion of Cladding Materials in Simulated BWR Environment using Impedance Measurements (2007)

Abstract In the present work, the corrosion of three Zircaloy-2 cladding materials have been studied in-situ in an autoclave using electrochemical impedance spectroscopy. Measurements were conducted in simulated boiling water reactor environment at temperatures up to 288°C, both in the pre-transition and the post-transition stage. In addition, impedance measurements were performed at room temperature on samples previously exposed to irradiation. This work clearly demonstrates that impedance spectroscopy can be used for in-situ studies of the corrosion of Zircaloy cladding materials in the pre-transition region at high temperatures. Oxide thickness, oxide conductivity, and effective donor density were successfully evaluated from the impedance data. Less information has been able to be gained from the impedance measurements in the post-transition region compared to the measurements in the pre-transition region. However, the thickness of the inner oxide layer, oxide conductivity, and oxide porosity were successfully evaluated from the impedance data. The measurements on irradiated samples of the same materials as investigated in autoclaves indicate that irradiation introduces defects in the oxide structure, resulting in a higher number of charge carriers and a more inhomogeneous oxide than produced under autoclave exposure.
Pulmonary hypoplasia and persistent pulmonary hypertension: favorable clinical response to high-frequency jet ventilation. (1992)

Pulmonary hypoplasia in the neonate is frequently fatal. This article reports two neonates with a clinical diagnosis of pulmonary hypoplasia complicated by persistent pulmonary hypertension (PPHN). Though both infants were progressively worsening while receiving conventional mechanical ventilatory support, they survived when treated with high-frequency jet ventilation.
ON APPLICABILITY OF ENERGY HARVESTING TECHNOLOGIES FOR EMERGENCY VICTIMS DETECTION SYSTEM BUILDING (2018)

In this paper we propose a technique for a potential distance calculation for a system of detection emergency situation victims equipped with passive radio-tags. This calculation is performed for three channel models: open territories, forest and snowy field. For every model a level of a reader signal received by radio-tag is estimated as a function of distance. Basing on characteristics of state-of-art systems-on-crystal used for radio-tags building an average energy consumption is estimated with a few polling rates. An quantitative characteristics of harvested electromagnetic energy generated by reader in a far field is calculated via electric model of harvester. Our study shows that a potential distance of investigated system based on energy harvesting technology doesn’t exceed 50 meters for typical scenarios.
On-wafer large signal power, S-parameter and waveform measurement system (1994)

An on-wafer measurement system has been developed for the complete characterization of the large signal behavior of transistors up to 40 GHz based on the microwave transition analyzer HP 71500A. The vector measurement capability of the MTA is utilized to allow full vector calibration of the measurement system for the fundamental and the higher harmonics. The error corrected waveforms at the transistor terminals are derived from the measurement data. Novel analysis concepts have been developed for the extraction of transistor characteristics and parameters from large signal RF measurements, i.e., RF current and voltage constraints associated with the output characteristic and the RF large signal transfer characteristic. These parameters, measured under real RF operating conditions, can be compared directly with DC or small signal S-parameter measurements. This is essential if large signal RF measurements are used for the optimization of high power transistor structures and in the development of accurate non-linear CAD models.
Recipient mononuclear cell recognition and adhesion to graft endothelium after human cardiac transplantation. Lymphocyte recognition leads to monocyte adhesion. (1994)

Transendothelial migration of mononuclear cells is crucial in the development of allograft rejection and transplant coronary disease. Adhesion of circulating cells to endothelium is the initial step in transendothelial migration. Human aortic endothelial cell cultures were established from aortic tissue harvested at the time of organ donation for cardiac transplantation which allowed specific recipient mononuclear cell-graft endothelial interactions to be studied. Confluent untreated endothelial cells were incubated with recipient mononuclear cells for 15 min to assess adhesion. Adhesion of recipient mononuclear cells to endothelium derived from their graft was threefold higher than adhesion to nonspecific endothelium (93 +/- 20 vs. 30 +/- 11 cells/high power field, P < 0.005). Graft-specific adhesion was inhibited by preincubation of the endothelium with antibodies to class I HLA (34 +/- 16 cells/high power field, P < 0.005). Immunofluorescence performed after adhesion showed that 73 +/- 6% of both specific and nonspecific adherent cells were monocytes. The use of purified lymphocyte and monocyte preparations showed that graft-specific lymphocytes induce unrelated monocytes to become adherent. These results suggest that lymphocytes are primed in vivo to recognize endothelium derived from their graft which leads to a rapid increase in lymphocyte and monocyte adhesion. Such allo-recognition may involve endothelial class I HLA molecules.

Metalloporphyrin Synergizes with Ascorbic Acid to Inhibit Cancer Cell Growth Through Fenton Chemistry (2010)

Ascorbic acid (AA) has been reported to inhibit tumor cell growth through the generation of extracellular hydrogen peroxide (H(2)O(2)). However, the clinical utility of AA has been limited by relatively low potency and in vivo efficacy. This study reports that the metalloporphyrin, Mn(III) tetrakis(N-methylpyridinium-2-yl)porphyrin(5+) (MnTMPyP), has a potent synergistic cytotoxic effect when combined with AA in a variety of cancer cell lines. In the presence of MnTMPyP, the concentration of AA required to inhibit cancer cell growth was markedly reduced. In vitro (cell-free) experiments demonstrated that AA alone enhanced the Fenton reaction that produces cytotoxic hydroxyl radical (HO(*)); however, this reaction was limited by the low rate by which AA generates H(2)O(2) (Fenton reaction substrate) from O(2). MnTMPyP catalyzed H(2)O(2) generation through the AA-facilitated Mn(II <--> III)TMPyP redox cycle and thereby markedly potentiated the Fenton reaction. Accordingly, MnTMPyP and AA resulted in increased cellular levels of H(2)O(2) and HO(*) in cancer cells, which mediate the synergistic cytotoxicity of this combined treatment. This effect was inhibited by cellular enzymes that metabolize H(2)O(2), such as catalase and glutathione peroxidase, suggesting that selective killing of cancer cells deficient in such enzymes can be achieved in vivo.

Doping effects on the kinetics of solid-phase epitaxial growth of amorphous alumina thin films on sapphire (1995)

The effects of doping on the kinetics of solid-phase epitaxial growth of amorphous alumina have been studied. Amorphous alumina Al2O3) thin films, 200–265 mm thick, were deposited on to (0001) sapphire substrates by electron-beam evaporation. Iron or chromium atoms were uniformly doped into the films during deposition to cation concentrations below 5 cationic %. The kinetics of the epitaxial growth were studied at 800–1050 °C in flowing oxygen gas by in situ time-resolved reflectivity techniques as well as by ion backscattering and channeling techniques. A phase transformation sequence from amorphous through gamma to alpha alumina has been observed in all the undoped and doped films. The transformation from γ to α alumina is a thermally activated process with an activation energy of 5.0±0.2 eV, independent of the presence of dopants. However, the presence of dopants affects the overall transformation rate. Fe enhances while Cr slows the growth rate relative to the undoped case.

Autofocus methods of whole slide imaging systems and the introduction of a second-generation independent dual sensor scanning method (2011)

Accurate focusing is a critical challenge of whole slide imaging, primarily due to inherent tissue topography variability. Traditional line scanning and tile-based scanning systems are limited in their ability to acquire a high degree of focus points while still maintaining high throughput. This review examines limitations with first-generation whole slide scanning systems and explores a novel approach that employs continuous autofocus, referred to as independent dual sensor scanning. This "second-generation" concept decouples image acquisition from focusing, allowing for rapid scanning while maintaining continuous accurate focus. The technical concepts, merits, and limitations of this method are explained and compared to that of a traditional whole slide scanning system.
Measurement of photon indistinguishability to a quantifiable uncertainty using a Hong-Ou-Mandel interferometer (2010)

We present a method for using the Hong-Ou-Mandel (HOM) interference technique to quantify photon indistinguishability within an associated uncertainty. The method allows the relative importance of various experimental factors affecting the HOM visibility to be identified, and enables the actual indistinguishability, with an associated uncertainty, to be estimated from experimentally measured quantities. A measurement equation has been derived that accounts for the non-ideal performance of the interferometer. The origin of each term of the equation is explained, along with procedures for their experimental evaluation and uncertainty estimation. These uncertainties are combined to give an overall uncertainty for the derived photon indistinguishability. The analysis was applied to measurements from an interferometer sourced with photon pairs from a parametric downconversion process. The measured photon indistinguishably was found to be 0.954+/-0.036 by using the prescribed method.
Interstrip characteristics of n-on-p FZ silicon detectors (2009)

We report on the measurement of interstrip parameters of p-type silicon strip sensors which we are developing in a large collaboration to be used in a future tracker for the LHC upgrade. We measure on test structures with about 1 cm long strips the interstrip resistance, interstrip capacitance (at 1 MHz) and punch-through protection both pre-rad and after irradiation with 70 MeV protons to a fluence of 1.5×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">13</sup> p/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , corresponding to about 1 MRad, from prototyping runs with Hamamatsu Photonics and Micron Semiconductors. We report the values for a variety of isolation scenarios of p-stops, p-spray and a combination of both.
Discrepancies of the Values on the Withholding Futile Interventions between Physician and Family Members of Terminal Cancer Patients (2001)

Values held on issues like therapeutic decision-making and the withholding of life-sustaining treatments in terminal cancer patients are discordant between physicians and family members. In order to resolve controversies on the role of physicians in end-of-life decisions, the values of physicians as well as patients and their family members should be considered in the final decision-making process.

Resonance! (1996)

There is something manly and invigorating about field data acquisition. True, we were only testing an acoustic logging sonde in the field at the rear of the research center, but here I was with spanking new overalls, work boots and gloves, and — best of all — my very own company hardhat (complete with logo). And I was mixing it up pretty well with the real field hands. While Spike rigged up, Bobby Joe and I had an in-depth discussion which quantitatively analyzed gas-station hot dogs in North Dallas. Then Bobby Joe got busy. Spike came into the cab to cool off and I soliloquized on the artistic genres of her tattoos.
Security analysis of NFC relay attacks using probabilistic model checking (2014)

Near Field Communication (NFC) is a short-ranged wireless communication technology envisioned to support a large gamut of smart-device applications, such as payment and ticketing applications. Two NFC-enabled devices need to be in close proximity, typically less than 10 cm apart, in order to communicate. However, adversaries can use a secret and fast communication channel to relay data between two distant victim NFC-enabled devices and thus, force NFC link between them. Relay attacks may have tremendous consequences for security as they can bypass the NFC requirement for short range communications and even worse, they are cheap and easy to launch. Therefore, it is important to evaluate security of NFC applications and countermeasures to support the emergence of this new technology. In this work we present a probabilistic model checking approach to verify resiliency of NFC protocol against relay attacks based on protocol, channel and application specific parameters that affect the successfulness of the attack. We perform our formal analysis within the probabilistic model checking environment PRISM to support automated security analysis of NFC applications. Finally, we demonstrate how the attack can be thwarted and we discuss the successfulness of potential countermeasures.
High-Speed Plasmid Isolation Using 96-Well, Size-Exclusion Filter Plates (2002)

The accelerating pace of genomics analysis has necessitated the abbreviation of DNA sample preparation protocols. We have developed a size-exclusion-based system for the rapid isolation ofplasmid DNA in a 96-well microplate format. This high-speed protocol employs a modified alkaline lysis methodfor the preparation of the bacterial lysate, followed by three short vacuum filtration steps. Unlike traditional bind/wash/elute methods, there is no need to use chaotropic salts or ethanol. The samples are recovered from the top side of the MultiScreen96 PLASMID plates. Starting with bacterial cell pellets, the entire prycedure for purifying the plasmid DNA can be performed in 30 min with a multichannel pipettor. The high yields, reproducibility, and quality of the plasmids make this system a good choice for any cloning or DNA sequencing operation.
Crystal growth and orientation in sputtered films of bismuth telluride (1964)

Abstract Films in the thickness range from 300 Å to 3 μ have been prepared by sputtering from a cathode of composition Bi2Te3 in an atmosphere of pure argon. At low substrate temperatures the stoichiometric Bi2Te3 composition is retained in the sputtered deposits, but with increasing temperature, above 250°c, progressive loss of Te occurs, until at 420°c the film composition corresponds approximately to BiTe. The Te-deficient film structures are identified as metastable β-type phases which are of the same structure type as Bi2Te3. On amorphous substrates fibre textures are developed which change from a {1015} to a {0001} type as the temperature is raised. The corresponding single-crystal orientations are obtained by epitaxy on the (100) and (111) planes respectively of NaCl crystals. The texture changes are accompanied by striking changes in the crystal habit. Hexagonal platelets appear at low temperatures and very high temperatures, while well-developed octahedra are observed at intermediate temperatures. These effects are interpreted by referring the structure to a reduced pseudo-cubic unit cell which assumes a random distribution of Bi and Te atoms on a cubic close-packed lattice. In terms of this unit, the low- and high-temperature textures are identified respectively as {100} and {111} nucleation orientations. The textures occurring at intermediate temperatures are attributed to growth orientations.
A Tapered Chalcogenide Microstructured Optical Fiber for Mid-IR Parabolic Pulse Generation: Design and Performance Study (2014)

This paper presents a theoretical design of chalcogenide glass based tapered microstructured optical fiber (MOF) to generate high power parabolic pulses (PPs) at the mid-IR wavelength (~2 μm). We optimize fiber cross-section by the multipole method and studied pulse evolution by well-known symmetrized split-step Fourier Method. Our numerical investigation reveals the possibility of highly efficient PP generation within a very short length (~19 cm) of this MOF for a Gaussian input pulse of 60 W peak power and full width at half maximum (FWHM) of 3.5 ps. We examined quality of the generated PP by calculating the misfit parameter including the third order dispersion and fiber loss. Further, the effects of variations in input pulse power, pulse width and pulse energy on generated PP were also studied from the point of view of tolerances in fabrication of such a device.
A gene(s) within the H-2D region determines the development of toxoplasmic encephalitis in mice. (1991)

Studies were performed in a murine model to determine if there is genetic control of the development of toxoplasmic encephalitis. Ten weeks after infection with the ME49 strain of Toxoplasma gondii, mice with the H-2b haplotype (C57BL/6, C57BL/10) and H-2k haplotype (C3H/He, CBA/J) developed remarkable inflammatory changes in their brains, whereas mice with the H-2a haplotype (A/J) and H-2d haplotype (BALB/c, DBA/2) did not. In the area of acute focal inflammation in mice with the H-2b and H-2k haplotypes, tachyzoites and toxoplasma antigens were demonstrated by immunoperoxidase staining, suggesting that the focal inflammation was induced by toxoplasma organisms. B10 congenic mice were used for further analysis of this genetic regulation. Presence of the encephalitis in B10 and B10.BR but not in B10.A and B10.D2 mice at 10 weeks after infection indicated regulation of the inflammation by a gene(s) within the H-2 complex. The encephalitis developed in B10.A (2R) and B10.A (4R) mice but not in B10.A (3R) and B10.A (18R) during infection. These results clearly indicated that the development of toxoplasmic encephalitis was controlled by a gene(s) in the H-2D region. The Qa and Tla genes did not appear to be critical in determining susceptibility to the encephalitis. There was no correlation between serum toxoplasma antibody titres and occurrence of the encephalitis. Injection of a monoclonal antibody to interferon-gamma (IFN-gamma) remarkably augmented the inflammatory changes in the brains of the infected B10 mice. In contrast, the treatment did not induce any inflammatory response in the brains of the infected BALB/c mice. A similar genetic regulation may be operative in determining development of toxoplasmic encephalitis in AIDS and other immunocompromised patients.
Variations of Tensile Strength of Myosin Gel by Heating (1995)

The variations of the tensile strength of myosin gel during heating were measured based on an equation, which was derived from the thermodynamics of elastic deformation, in orderto clarify the mechanism of the elasticity of kamaboko. Myosin was extracted from the croaker Nibea mitsukurii, and 85mg protein/g gel/0.6M KCl was prepared by heating at 80°C for 20min. The myosin gel was extended to twice its original length, and successively heated by an electric heater alone or in combination with an infrared ray. A commercially available kamaboko and a rubber band were also submitted to the experiments to compare with the myosin gel. The tensile strength of both myosin gel and kamaboko increased and immediately decreased when these gels were heated by the electric heater and it continuously decreased with heating by an infrared bulb. In the case of rubber, on the other hand, the tensile strength increased continuously. From the results of myosin gel and kamaboko, the entropy of these gels was found to increase with elongation under a constant temperature. Hence, both myosin gel and kamaboko were found to have another mechanism for elasticity, different from that of rubber, or entropy elasticity. As a result, myosin gel was concluded to be an energy elastic body, not an entropy one.
