Multicast based Dual Amplify and Forward relay scheme for 2-hop networks (2009)

The use of multicasting over multi-hop networks seems an attractive new way to provide support to real-time applications like video streaming. In this paper, we proposed a 2-hop Dual Amplify-and-Forward (DAF) relay scheme. In this scheme, only the intermediate nodes (relay nodes) can cooperate with each other and there is no cooperation between transmitting and receiving nodes. This scheme has achieved a 4 dB gain over the earlier proposed 2-hop multicast based virtual MIMO relay scheme. In this paper we compare the two multicast relay schemes and analyze their performance with the help of MATLAB simulation.

Ramifications of codoping SrI2:Eu with isovalent and aliovalent impurities (2016)

Eu2+ doped SrI2 is an important scintillator having applications in the field of radiation detection. Codoping techniques are often useful to improve the electronic response of such insulators. Using first-principles based approach, we report on the properties of SrI2:Eu and the influence of codoping with aliovalent (Na, Cs) and isovalent (Mg, Ca, Ba, and Sn) impurities. These codopants do not preferably bind with Eu and are expected to remain as isolated impurities in the SrI2 host. As isolated defects they display amphoteric behavior having, in most cases, significant ionization energies of the donor and acceptor levels. Furthermore, the acceptor states of Na, Cs, and Mg can bind with I-vacancy forming charge compensated donor-acceptor pairs. Such pairs may also bind additional holes or electrons similar to the isolated defects. Lack of deep-to-shallow behavior upon codoping and its ramifications will be discussed.

Power coordination of grid-connected wind turbine doubly fed induction generator augmented with battery storage (2013)

Wind power tends to be unsteady because it is influenced by natural and meteorological conditions, so, there is a need of energy storage system that takes care of this wind power variation. The integration of a battery energy storage system (BESS) with a wind turbine doubly fed induction generator (DFIG) can make these intermittent in wind power more dispatchable. This paper focuses on the development of a control strategy for optimal use of the BESS for this purpose. A rule-based control scheme is considered as a solution of this optimal control problem defined, to incorporate the operating constraints of the BESS, such as state of charge limits, charge/discharge current limits, and lifetime. The goal of the control is to have the BESS provides power as much smoothing as possible so that the output power of the DFIG can be maximized at all wind speed independent of the estimated grid power required. Two objectives are targeted in the paper. The first objective is to obtain the maximum output power out of the existing wind regime. This is achieved by controlling the voltage injected to the rotor terminals. The second objective is to supply the demand power commitment to the grid. This is achieved by controlling the battery power flow. The size of the battery is calculated to accommodate excess power and to compensate for the deficit power according to the wind regime and the grid power demand.
Silicide layer growth rates in Mo/Si multilayers (1993)

The thermal stability of sputter-deposited Mo/Si multilayers was investigated by annealing studies at relatively low temperatures (˜ 250-350 °C) for various times (0.5-3000 h). Two distinct stages of thermally activated Mo/Si interlayer growth were found: a primary surge, followed by a (slower) secondary steady-state growth in which the interdiffusion coefficient is constant. The interdiffusion coefficients for the interlayer formed by deposition of Mo-on-Si are higher than those of the interlayer formed by deposition of Si-on-Mo. Assuming that the activation energy is constant, an extrapolation of our results to ambient temperature finds that interlayer growth is negligible, suggesting long-term thermal stability in soft-x-ray projection lithography applications.

Comparision of wide band gap semiconductors for power electronics applications (2008)

Recently, power electronic devices have reached fundamental limits imposed by the low breakdown field, low thermal conductivity and limited switching frequency of Si. Substantial improvements can only be achieved by turning over to semiconductors showing remarkable performance in the frame. These are WBG semiconductors which constitute GaN, SiC and diamond which have long been swashed for their potential superior performance in high frequency and high power applications. This review paper envisages, the core aspects of WBG semiconductors, comparison on the basis of their characteristics and their applicability in power electronics. It also includes an overview of the market for WBG semiconductors and the future perspective for power devices.
Role of Magnetic Resonance for Assessing Structure and Function of Trabecular Bone (2002)

The strength of trabecular bone and its resistance to fracture traditionally have been associated with apparent density. This paradigm assumes that neither the ultrastructural nor microstructural make-up of the bone is altered during aging and osteoporosis. During the past decade there has been growing evidence from both laboratory and clinical studies against this view. Recent advances in noninvasive imaging technology, notably micro-magnetic resonance imaging (micro MRI) and computed tomography, offer an opportunity to test the hypothesis that architecture is an independent contributor to bone strength. MRI appears to be ideally suited for this task because bone marrow has uniform high signal intensity while bone appears with background intensity, thus yielding a binary system tomographic system. However, in vivo trabecular bone imaging is hampered by the limited signal-to-noise ratio that precludes voxel sizes much smaller than trabecular thickness, which would be required to yield a bimodal intensity histogram for segmentation of the image into bone and marrow. The resulting partial volume blurring leads to fuzzy boundaries. Successful structure analysis thus demands more elaborate processing strategies. This article reviews new approaches conceived in the authors' laboratory toward acquisition, processing, and structural analysis of trabecular bone images in the limited spatial resolution regimen of in vivo micro MRI. These methods are shown to provide detailed insight into the three-dimensional trabecular network topology and scale at the distal radius or distal tibia that typically serve as surrogate sites. The micro MRI-derived structural parameters are shown to be associated with the bone's biomechanical properties and fracture resistance. Further, the technology has advanced to a stage permitting serial studies in laboratory animals and humans as a means to evaluate the effects of treatment. The method currently is confined to peripheral skeletal sites, and its extension to typical fracture sites such as the proximal femur hinges on further advances in detection sensitivity.
Redfield topology of the lattice-ordered group of regular measures on a locally compact and sigma compact topological space. (1980)

En este trabajo se estudia la topologia de Redfield (R-topologia) en el espacio de las medidas finitas y regulares sobre un espacio topologico numerable en el infinito. Para ello debemos estudiar bajo que condiciones suficientes se puede asegurar que una medida bivalorada es exactamente una carga puntual. En general esta afirmacion no es cierta y de ahi las condiciones restrictivas impuestas sobre el tipo de medidas y sobre la naturaleza del espacio topologico en lo que se refiere a la compacidad.
Los resultados a que se llega son los siguientes: El grupo reticulado de todas las medidas es producto directo de las medidas concentradas en puntos (necesariamente una cantidad numerable) y de las medidas difusas (sin cargas puntuales). La R-topologia es grosera sobre la parte difusa y sobre la parte concentrada es Hausdorff y coincide con la topologia de la convergencia puntual de saltos.
[An experimental study of metacresol burn]. (1999)

To study the characteristics of metacresol burn.Metacresol of 99.6% was used. The animals were randomly separated into control group, excision group, topical SD-Ag group, saturated sodium sulfate wet compress group, and warm running water flushing group.It was proved that metacresol could not only cause deep burns to skin but also penetrate skin and to produce impairment of functions of the main internal organs of the body, as shown by abnormalities in blood BUN, GPT, GOT, GGT, and AKP. Pathological changes were also found in the liver, heart, brain, kidney, and skin with light and electron microscopy.Through comparison of the four different treatment methods for metacresol burns, it is concluded that excision of the wound followed by skin grafting should be done as early as possible to minimize absorption of the chemical. Topical application of SD-Ag or sodium sulfate wet compress, and flushing with running water can alleviate direct injury to skin. Drugs to protect the heart, liver, and kidney should be used for a longer period than usual.

Antillatoxin is a sodium channel activator that displays unique efficacy in heterologously expressed rNav1.2, rNav1.4 and rNav1.5 alpha subunits (2010)

ATX displayed a unique efficacy with respect to stimulation of sodium influx in cells expressing rNa(v)1.2, rNa(v)1.4 and rNa(v)1.5 α-subunits. The efficacy of ATX was distinctive inasmuch as it was not shared by activators of neurotoxin sites 2 and 5 on VGSC α-subunits. Given the unique pharmacological properties of ATX interaction with sodium channel α-subunits, decoding the molecular determinants and mechanism of action of antillatoxin may provide further insight into sodium channel gating mechanisms.
Volatilization of Lindane and DDT from Soils (1970)

Abstract Four soils ranging in texture from a loamy sand to a clay were amended separately with 14 C‐labeled lindane and DDT to give a concentration of 10 ppm. Pesticide volatilization was determined each day for three consecutive drying cycles at 30C and 55C by liquid scintillation counting of trapped pesticide vapors. Soils were initially wetted to ⅓ bar suction and dried by passing dry air over the soil surface. Neither pesticide was volatilized at either temperature after the soils contained less than a monolayer of water. Since these soils became dry at different times during the 14‐day drying cycle, two factors were important in describing pesticide volatilization. First, the rate of pesticide loss was constant for each soil in the moisture range from ⅓ bar to 15 bars. Second, since essentially the same amount of water was lost from each soil per day until dryness, the pesticides were volatilized over a longer period of time from the finer textured soil than from the coarser textured soils. A mechanism is proposed. Volatilization rates for DDT and lindane from soil containing moisture greater than 15 bars tension were dependent on temperature, adsorptive characteristics of the soil, and concentraction of the pesticide (lindane). For lindane and DDT at 30C, the rate of volatilization from soil was in the order Valentine loamy sand > Hand loam > Raber silty clay loam > Promise clay. Degradation of lindane to PCCH occurred at 30C and 55C. After three wetting and drying cycles at 55C, the amount of DDT converted to DDE ranged from 6.7% for Valentine loamy sand to 21.2% for the Raber silty clay loam.

Heparin Osteoporosis (1965)

Studies of 117 patients on long-term sodium heparin therapy disclosed cumulative evidence of a relationship between prolonged use of large amounts of heparin and osteoporosis. No symptoms of osteoporosis developed in 107 who received 10,000 units of concentrated sodium heparin once daily or less for 1 to 15 years. Of ten treated daily with larger doses (15,000 to 30,000 units) for six months or longer, spontaneous fractures of vertebrae or ribs developed in six, and biopsies disclosed soft, bony matrix. Studies of rats on sufficient heparin therapy to triple clotting for ten days indicated that collagenolytic activity of rat-bone-cell homogenate increased two to four times, and the stability of the lysosome-like bodies in bone cells which contain collagenase appears to be decreased. If these observations are true, hyperheparin states, whether spontaneous or man-induced, may take their place in the small growing category of lysosomal diseases.
Clinical associations of autoantibodies to human muscarinic acetylcholine receptor 3213–228 in primary Sjogren's syndrome (2005)

The presence of m3AChR(213-228) antibodies is a common feature in pSS. Although it is significantly more common in pSS than in the comparison groups, anti-m3AChR(213-228) positivity is not exclusive to pSS.

Beamwidth-adjustable low sidelobe beamforming for space-time diversity (2003)

Extending space-time coding (STC) from element to beam domain has been considered in the past without taking into account the condition that diversity branches must be independent and identically distributed (i.i.d.). Although in element-space such a simple statistical channel model can be used under the assumption that antenna elements are placed sufficiently apart one from another, in beam-space a more realist multipath channel model must be dealt with. The required inter-element spacing to guarantee i.i.d. conditions can be theoretically determined given the nominal angular spread of the channel, and for relatively narrow angular spreads such inter-element spacing can be prohibitive. A major issue is, therefore, whether beamforming can extract i.i.d. diversity branches from a multipath scenario, thus enabling beam-space when element-space is not practical. In this paper we propose a beamforming method that allows the design of beamwidth-adjustable low sidelobe beampatterns and investigate its application to extracting i.i.d. channel conditions out of a multipath channel with Gaussian path density spatial distribution.
Nonlinear resonant ultrasound spectroscopy (NRUS) applied to damage assessment in bone (2005)

Nonlinear resonant ultrasound spectroscopy (NRUS) is a resonance-based technique exploiting the significant nonlinear behavior of damaged materials. In NRUS, the resonant frequency(ies) of an object is studied as a function of the excitation level. As the excitation level increases, the elastic nonlinearity is manifest by a shift in the resonance frequency. This study shows the feasibility of this technique for application to damage assessment in bone. Two samples of bovine cortical bone were subjected to progressive damage induced by application of mechanical cycling. Before cycling commenced, and at each step in the cycling process, NRUS was applied for damage assessment. For independent assessment of damage, high-energy x-ray computed tomography imaging was performed but was only useful in identifying the prominent cracks. As the integral quantity of damage increased, NRUS revealed a corresponding increase in the nonlinear response. The measured change in nonlinear response is much more sensitive than the change in linear modulus. The results suggest that NRUS could be a potential tool for micro-damage assessment in bone. Further work must be carried out for a better understanding of the physical nature of damaged bone and for the ultimate goal of the challenging in vivo implementation of the technique.
Organ‐Specific Metastases in Melanoma: Experimental Animal Models (1993)

Metastases from certain primary tumors frequently exhibit specific organ preference. Animal models have been developed to induce in a reproducible fashion the formation of organ-specific metastases by malignant melanoma cells. Some of these models rely on the use of immunodeficient mice, which can support the growth of murine as well as human malignant melanomas. Moreover, immunodeficient mice, because of their diminished ability to mount an effective immune response, allow the expression of malignant properties (e.g., preferential colonization of certain organs), which are intrinsic to transplanted melanoma cells. This review discusses the relevant factors (and limitations) of some of the animal models used to study the in vivo properties of melanoma cells.
Preparation of Mixtures of Humidified Air with CO, SO<sub>2</sub>, NO<sub>2</sub>, NH<sub>3</sub>, NH<sub>2</sub>CH<sub>3</sub>, Cl<sub>2</sub>, and HCl to Measure Respirator Cartridge and Canister Service Life (1975)

Four systems have been fabricated to measure the effective service life of respirator cartridges and canisters;. The four systems employ carbon monoxide, sulfur dioxide/nitrogen dioxide, ammonia/methylamine, and chlorine/hydrogen chloride as contaminants. Each system produces test concentrations in the low percentage range (typically 0.05 to 3.0%) at flow rates of 32 and 64 liters/min and at relative humidities between 20 and 95%. Suitable anlyzers have been provided to measure the downstream concentration from 1 to 500 ppm as a function of time. Holders have been designed to accommodate the wide size variation of commercially available cartridges and canisters.
The Fibroblast and Nitric Oxide (2000)

The fibroblast typically is found in loose connective tissue where it is considered to be the principal cell type. Fibroblasts are responsible for the synthesis of the extracellular matrix proteins including collagen, elastin, and reticular fibers, as well as the complex carbohydrates of the ground substance. In addition, during pathophysiological processes such as wound healing, the fibroblast can change phenotype, differentiate into a myofibroblast, and exhibit properties characteristic of both smooth muscle and conventional fibroblast cells. The role of fibroblasts during wound repair was reviewed recently, and the diverse functions for fibroblasts and their interaction with other cell types during wound healing was discussed (1,2). In addition to matrix production, those functions include growth factor production, proliferation and migration, protease release, formation and contraction of granulation tissue, and phenotypic changes to a myofibroblast or to apoptosis.
An optimized DC-to-DC converter topology for high-voltage pulse-load applications (2002)

This paper presents the study of a high-voltage DC/DC resonant converter which has excellent behaviour to be used in applications with strong variations in output voltage and in output current, because it maintains high efficiency in these types of applications. To do so, the switching losses have been minimized by integrating all parasitic elements (leakage inductance, secondary side capacitance of the high-voltage transformer and parasitic capacitances of the power switches and diodes) into the power topology, and the conduction losses have been minimized by operating the converter in a special mode (optimum switching line) in which no reactive energy is returned from the resonant elements to the input voltage source. The type of control used (PWM phase-shifted) allows one to maintains these desirable characteristics even when the operating point suffers a very strong variation. The final power topology might be called a "full-bridge, clamped mode, LCC-type parallel resonant converter with capacitive output filter".< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
C-Reactive Protein Concentration in Dogs with Various Diseases (2008)

To investigate the clinical utility of C-reactive protein (CRP) determination in dogs, its plasma concentration was measured by a laser nephelometric method in 928 dogs with various diseases, and was compared with other inflammatory parameters. CRP concentration was elevated in various inflammatory diseases, this was most frequently observed in cases with neoplastic and immune-mediated diseases. All cases of pyometra, panniculitis, acute pancreatitis, polyarthritis, and hemangiosarcoma showed significantly elevated CRP concentrations. On the other hand, the CRP concentration was elevated only in few cases of neurological diseases such as epilepsy, meningoencephalitis, and hydrocephalus and endocrine diseases such as hypothyroidism, hyperadrenocorticism, and diabetes mellitus. Only a weak correlation was observed between the CRP concentration and white blood cell (WBC) counts (r=0.44) but no correlation with band neutrophil counts. There was no correlation between the CRP and albumin concentrations, but a weak negative correlation (r=-0.40) when excluding chronic intestinal diseases and nephrotic syndrome, which can cause protein loss. Thus, CRP can be useful to detect inflammations that cannot be detected by WBC and, or band neutrophil counts, suggesting that the examination of CRP concentration is essential as routine diagnostic test.
