Improved Rain Attenuation Correction Algorithms for Radar Reflectivity and Differential Reflectivity with Adaptation to Drop Shape Model Variation (2006)

One important goal of the Collaborated Adaptive Sensing of the Atmosphere (CASA) Engineering Research Center is to observe and monitor hazardous weather events in the low troposphere (below 1 km) by deploying networks of small, low- cost radars with small antennas. The first generation of CASA radar networks with dual-polarization capabilities is being deployed in Oklahoma. To achieve good sensitivity with small antenna size, high frequencies (X-Band) are selected. It is well known that signals transmitted at such high frequencies suffer attenuation due to rain along the propagation path. This article describes improved rain attenuation correction algorithms which correct radar reflectivity (Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">h</sub> ) and differential reflectivity (Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dr</sub> .) through measured differential propagation phase (Phi <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dp</sub> ).
A simple induction motor parameter estimation method for vector control (2007)

This paper presents a simple self-commissioning algorithm to estimate various motor parameters for Rotor-Flux-Oriented (RFO) induction motor drive. As the parameters are calculated from simple voltage equations and integration, it is possible for the proposed algorithm to be included in the main program with a low cost micro-controller. Also, it works well under arbitrary operating condition, and it is robust to measurement noise.
Recognizing and Treating Premenstrual Dysphoric Disorder (2002)

During their menstrual cycles, many women of repro-ductive age experience adverse physical, emotional, andcognitive symptoms that often recur, usually during theluteal phase of their cycle. These symptoms have greatpotential to interfere with personal, social, and occupa-tional functions. A constellation of severe symptoms maybe indicative of premenstrual dysphoric disorder(PMDD), a severe form of premenstrual syndrome(PMS).

Domain wall fermion calculation of nucleon G{sub A}/G{sub V} (2000)

The authors present a preliminary domain-wall fermion lattice-QCD calculation of isovector vector and axial charges, g{sub V} and g{sub A}, of the nucleon. Since the lattice renormalizations, Z{sub V} and Z{sub A}, of the currents are identical with DWF, the lattice ratio (g{sub A}/g{sub V}){sup lattice} directly yields the continuum value. Indeed Z{sub V} determined from the matrix element of the vector current agrees closely with Z{sub A} from a non-perturbative renormalization study of quark bilinears. They also obtain spin related quantities {Delta}q/g{sub V} and {delta}q/g{sub V}.
A high efficiency three-phase AC motor drive converter that utilized the neutral point of a motor (2009)

This paper exams a three-phase power converter that utilized the neutral point of the motor and demonstrates the motor performance of the proposed converter under various operating conditions. The structure of the proposed circuit is basically consisting of an AC/AC converter (Indirect Matrix Converter (IMC)) and a boost converter that connected to the neutral point of an induction motor. Boost converter will connect to batteries to serve as a secondary input power source of the system. Secondary input power will be injected directly into the DC link voltage of the IMC. In addition, this paper also demonstrates that the DC link voltage of the indirect matrix converter is stable and capable for an additional DC power source connection. Several motor test data such as speed-torque characteristic, torque impact and acceleration-deceleration characteristic are included to confirm the performance of the induction motor. Furthermore, experimental analysis proved that this converter is low loss when controlling with carrier comparison method of either the symmetrical method or the asymmetrical method.
Fairness in electronic commerce (1998)

Commerce over open networks like the Internet, sometimes referred to as electronic commerce, is becoming more widespread. This makes it important to study, and solve the security problems associated with electronic commerce. There are three prominent characteristics of commerce which are relevant in this respect. First, the crux of a commercial transaction is usually one or more exchanges of items of value. Second, players in a commercial transaction do not necessarily trust each other fully. Thus, protecting players from each other is as important as protecting them from outside attackers. Third, commercial transactions have legal significance. Therefore, it must be possible to gather sufficient evidence during the transaction to enable correctly behaving players to win any subsequent disputes. This dissertation addresses the problem of fairness in electronic commerce. A system that does not discriminate against a correctly behaving player is said to be fair. Several protocols are p...
Genotypic and Environmental Effects on Grain Yield and Quality of Oat Grown in North Dakota (2001)

The grain yield and quality determine much of the value of an oat ( Avena sativa L.) crop to the producer. This study investigated effects of genotype and environment on grain yield and quality. Twelve oat genotypes were grown during 3 yr at four locations in North Dakota where detailed environmental data were being collected. Grain yield, test weight, groat percentage, groat weight, and groat composition (protein, oil, β‐glucan, and starch concentrations) were evaluated. Results were subjected to analysis of variance and influences of environmental factors were evaluated by correlation analysis. Analysis of variance suggested that grain yield, groat starch, and ash concentrations were more strongly affected by environment than by genotype. Test weight, groat percentage, groat weight, protein, and β‐glucan were about equally influenced by environment and by genotype, whereas groat lipid was more strongly influenced by genotype. Significant environment × genotype interactions for all characteristics were attributed to differential resistance of genotypes to crown rust (caused by Puccinia coronata Corda var. aveneae W.P. Fraser & Ledingham) infection. Environments severely affected by crown rust produced grain with lower test weight, groat weight, and groat percentage in susceptible genotypes. Correlation analyses suggested that warm, bright (high solar radiation) spring weather, and cooler summer weather without excessive rains during grain filling generated the best oat yields with high quality grain.
Extracellular matrix profiles in the progression to heart failure (2008)

The myocardial extracellular matrix (ECM), which preserves the geometry and integrity of the myocardium, is a dynamic structure whose component proteins are maintained by a finely controlled homeostatic balance between deposition and degradation. One of the key targets in cardiology is the elucidation of the molecular mechanisms which mediate pathological remodelling of this matrix causing the transition from compensatory hypertrophy to congestive decompensated heart failure. In response to injury or increased workload, cardiac remodelling including myocyte hypertrophy, develops as the heart attempts to compensate for increased wall stresses. Persistence of these stresses over extended time periods leads to disruption of ECM homeostasis resulting in irreversible maladaptive cardiac remodelling, ventricular dilatation and finally heart failure. ECM remodelling is regulated by the matrix metalloproteinases (MMPs) and their endogenous inhibitors (TIMPs). Clinical studies and experimental models of cardiac disease states have reported alterations in the balance between the MMPs and TIMPs in the failing heart and crucially at intermediate time points in the progression to failure. This article reviews the recent clinical, genetic and experimental approaches employed to compare ECM, MMP and TIMP profiles in healthy, compensated and failing hearts and identifies common themes in the perturbation of ECM homeostasis in the transition to heart failure.
Numerical simulation of compressible Navier-Stokes flow in a double throat nozzle (1987)

Flow through a double throat nozzle has been computed for Reynolds numbers by 100, 400 and 1,600 on three different grid sizes. The computations were performed using a modified two-dimensional version of Shang's Navier Stokes code which employs MacCormak's explicit finite difference algorithm. The computations establish a benchmark against which new developments can be verified and also add to the growing confidence in this approach for applications to more complex flow situations.

[Microsurgical elimination of foot soft tissue defects with free vascularized flaps]. (1997)

The results of 40 microsurgical transplantations of complex flaps in 37 patients with cicatricial-ulcerous foot deformations are analysed. The surgery was indicated in cicatricial soft tissues defects, unhealing trophic ulcers, inability to use local tissues for plastic surgery. The scapular flap was used in 34 cases, thoraco-dorsal flap in 5 cases, deltoid flap in 1 case. It was necessary to increase the square of the scapular flap in case of a vast cicatricial soft tissue defect of the talocrural joint and dorsal surface of the foot and the sole. A special expander was used for this purpose. The importance of ultrasound methods for evaluation of the vessels supplying the sole, as well as the state of the microvascular anastomoses in postoperative period is stressed. The long-term results were followed up for 1.5 to 5 years in 29 of 37 patients. The good results was noted in 18 patients, satisfactory in 7 patients, complications (unhealed trophic ulcers) in 4 patients. The complications were caused by calcanel tuber deformation with osteophyte, osteomyelitis, inradically removed scars.

How Safe Is Aggressive Statin Therapy? (2006)

The most recent guidelines of the National Cholesterol Education Program recommend more aggressive low-density lipoprotein cholesterol goals: <100 mg/dL for patients at moderate or high risk of cardiovascular disease, and <70 mg/dL for patients at very high risk. These lower goals are more likely to be achieved using the more powerful statins--atorvastatin, rosuvastatin, and simvastatin. Although statins are widely used, extensively studied, and known to have an excellent safety profile, the perception of many health care providers and patients is that safety concerns about the more efficacious statins, especially at high doses, limit their use. However, clinical data consistently support the view that adverse events are uncommon even when intensive therapy is used to reach aggressive low-density lipoprotein cholesterol goals. Overall, the more potent statins have similar safety profiles. The benefits of aggressive statin treatment in reducing the risk of cardiovascular events appear to far outweigh any potential risks of adverse events.
Immunization with nonstructural proteins E1 and E2 of cottontail rabbit papillomavirus stimulates regression of virus-induced papillomas (1995)

Cottontail rabbit papillomavirus is the major animal model for cancer-associated papillomaviruses. Here we show that vaccination with the nonstructural proteins E1 and E2 induces the regression of virus-induced papillomas and that vaccination is equally effective when proteins are given with and without adjuvant. There was no correlation between antibody levels and regression, suggesting that tumor regression may be due to a cell-mediated response.
Fire and flood: Soil-stored seed bank and germination ecology in the endangered Carrington Falls Grevillea (Grevillea rivularis, Proteaceae) (2008)

Abstract Seed germination is dependent on the interaction between the dormancy state of a seed and the presence of favourable environmental conditions. Thus, the spectacular pulse of seedling recruitment in many Australian vegetation communities following disturbances such as fire can be attributed to changes in microsite conditions and/or the dormancy-breaking effect of the disturbance on accumulated seed banks. Grevillea rivularis is a threatened species endemic to the area immediately above Carrington Falls in the NSW Southern Highlands. Most of the population is confined to the riparian vegetation zone in woodland and heath, and is therefore subject to periodic disturbance from fire and flood. For this species, a pulse of seedling recruitment has been recorded after fire, flood and mechanical soil disturbance. The aims of this study were to examine the density and vertical distribution of the soil-stored seed bank and to investigate the role of heat and scarification as cues for germination of fresh and soil-stored seed. There was a large seed bank under the canopies of established individuals (194 ± 73 seeds m−2) and most seeds were found in the 0–2 cm and leaf-litter layers of the soil profile. The germination response of soil-stored and fresh seed was examined using a hierarchical series of laboratory experiments. Seeds of G. rivularis showed marked dormancy polymorphism. Thirty-six percent of soil-stored seed germinated without treatment, whereas no untreated fresh seeds germinated. Scarification or heating caused significant germination of dormant soil-stored seed, but only scarification resulted in germination of dormant fresh seeds. These results highlight important differences in the dormancy state of soil-stored and fresh seed. Thus, being a riparian species in a fire-prone environment, the dormancy mechanisms in seeds of G. rivularis suit this species to disturbance by both fire and flood.

Survey of Attitudes for Non-Millennials Who Do Not Consume Lamb (2017)

ObjectivesLamb consists of the smallest percentage of red meat consumption in the U.S. Our objective was to estimate how many Americans do not consume lamb and describe attitudes as to why they do not.Materials and MethodsA survey was constructed using Qualtrics software and distributed using the university’s alumni email list. The online survey consisted of demographic information, lamb consumption patterns and experiences. Participants were invited to complete the survey if they were within the non-millennial population (ages 35 and older) and residing in the U.S. Results were analyzed using Chi Square with α set at 0.05.ResultsParticipants (n = 7,246) were 53.7% male, 46.2% female (P < 0.0001); 26.6% were ages 35 to 44, 32.9% were 45 to 54, 25.1% were 55 to 64, and 17.1% were 65 or older (P < 0.0001); 91.9% were Caucasian (Non-Hispanic), 4.6% Latino or Hispanic, 1.1% Asian or Pacific Islander, 0.9% African American, and 1.4% other (P < 0.0001). Household income was 1.1% $24,999 or less, 4.8% $25,000 to 49,999, 11.8% $50,000 to 74,999, 15.0% $75,000 to 99,999, and 67.3% made $100,000 or more (P < 0.0001); 22.2% were not employed, 10.7% were employed part-time, and 67.0% were full-time (P < 0.0001). Participants reported consumption of the following protein sources either away from or at home: 96.5% chicken, 94.7% beef, 88.5% pork, 88.2% fish, 5.4% lamb, 95.0% eggs, and 21.0% soy-based products. 78.5% of the participants claimed to have eaten lamb before (P < 0.0001), and of these participants (n = 5669), 61.2% selected having a positive eating experience with lamb (P < 0.0001). Although 36.4% of the participants were uncertain how the lamb was prepared (P < 0.0001), grilling outside (13.4%), and roasting (28.1%) were the most common methods of preparation. 52.6% of the participants would be willing to try lamb again (P < 0.0001), 30.9% selected maybe, and 16.5% would not be willing to try lamb again. Of the participants who had not tried lamb before (n = 1554), 57.3% would be willing to try lamb (P < 0.0001). If lamb flavor were to be improved, 17.2% of the participants would definitely and 56.3% might consume more lamb (P < 0.0001). If lamb tenderness were to be improved, 18.2% of the participants would definitely and 53.7% might consume more lamb (P < 0.0001). If eating quality of lamb were to be more consistent, 17.5% of the participants would definitely and 54.2% might consume more lamb (P < 0.0001). If lamb were to be implemented into the fast food industry, 21.8% of the participants would definitely and 33.7% might consume more lamb (P < 0.0001). While 71.4% of the participants selected they had never looked to buy lamb at their local grocery store, 14.1% selected lamb is hard to find and 5.9% selected finding lamb was hit or miss.ConclusionWe concluded that opportunities exist to increase the consumption of lamb by converting the non-millennial non-consumers of lamb.

Chlorogenic acid/chromium supplement rescues diet-induced insulin resistance and obesity in mice (2015)

Abdominal obesity is a major risk factor for insulin resistance, type 2 diabetes and cardiovascular diseases. Dietary fat induces insulin resistance in humans and rodents. The current study investigates whether a Chlorogenic acid/Chromium III supplement rescues obesity and insulin resistance caused by high-fat feeding of male C57BL/6 J mice for 7 weeks. Administering an oral daily dose of this supplement in the last 3 weeks of feeding reversed diet-induced body weight gain and insulin resistance, assessed by hyperglycemia, glucose intolerance and insulin intolerance. Indirect calorimetry analysis revealed that this effect is mediated at least partly, by increasing energy expenditure and spontaneous locomoter activity. These findings underscore the important role that chlorogenic acid and chromium play in maintaining glucose metabolism and insulin response in mice fed a high-fat diet.
Synthesis of Multibranched Australine Derivatives from Reducing Castanospermine Analogues through the Amadori Rearrangement of <i>gem</i>-Diamine Intermediates: Selective Inhibitors of β-Glucosidase (2014)

A practical one-pot synthesis of bi- and triantennated australine analogues from a pivotal sp(2)-iminosugar-type reducing castanospermine precursor is reported. The transformation involves a gem-diamine intermediate that undergoes the indolizidine → pyrrolizidine Amadori-type rearrangement and proceeds under strict control of the generalized anomeric effect to afford a single diastereomer. The final compounds behave as selective competitive inhibitors of β-glucosidase and are promising candidates as pharmacological chaperones for Gaucher disease.
Toxicity of photodynamic therapy with photofrin in the normal rat brain (1994)

The widespread acceptance of photodynamic therapy (PDT), a potential adjuvant brain tumor therapy under clinical evaluation since 1980, has been partially restrained by its potential toxicity toward normal brain tissue. This study examined PDT-produced injury of normal rat brain as a function of photosensitizer dose. Brain injury was characterized by correlating measurements of the area of cerebral edema using T2-weighted magnetic resonance images, measurement of brain water content at the lesion site, microscopic examination of histological sections through the PDT lesion, and by evaluation of the area of blood brain barrier (BBB) disruption using computerized morphometric analysis of the region of Evans blue (EB) dye-labelled albumin extravasation. Monochromatic red light (630 nm) was delivered intracerebrally using a 5-mm-long cylindrical, diffusion-tip optical fiber at a constant energy dose of 15 joules. A Photofrin dose of 2 mg/kg of body weight produced a transient breakdown in the blood brain barrier around the site of the implanted optical fiber demonstrated by magnetic resonance imaging (MRI), extravasation of EB dye and pallor on hematoxylin and eosin-stained microscopic tissue sections. A much larger area of BBB disruption was seen at a dose of 4 mg/kg of Photofrin, and this drug dose resulted in significant permanent brain injury. In this model, a Photofrin dose of 4 mg/kg body weight is not tolerated by the normal brain.
