Modeling of Rattlesnake Creek Watershed Using Swat Model (1996)

Watershed scale models are widely used in design and operation of river basin projects and for guiding public decisions. This paper presents modeling details of Rattlesnake Creek watershed in south-central Kansas. The Soil and Water Assessment Tool (SWAT) model was utilized for this purpose. This model was developed by USDA, ARS, Grassland Soil & Water Research Laboratory, Texas. Parameter estimation and sensitivity analysis were carried out using historical data such as precipitation, temperature, land use, land cover, conservation practices, stream flow and weather information. These results will be used to calibrate the model and to predict the effect of managing water rights and land use changes on the surface yield.
CXCL12-CXCR4 Axis in Ulcerative Colitis (2011)

Regulated immune responses are essential to maintain intestinal homeostasis and require direct or indirect communication among cells. Communication that occurs among cells in the absence of direct contact is often through the use of cytokines and chemokines. Ulcerative colitis (UC) and Crohn's disease (CD) are chronic intestinal inflammatory bowel diseases (IBD). IBD is characterized by increased influx of immune cells to the mucosa of genetically susceptible hosts. The characteristic increase of inflammatory infiltrate is mainly of T cells recruited to the lamina propria (LP) by a multistep process that involves the integrated interactions and effects of adhesion molecules and chemokines (1). Numerous studies in IBD patients and in animal models of colitis have demonstrated that both inflammatory chemokines and their receptors are up-regulated in settings of active inflammation (2). More importantly, blockade or absence of various chemokine receptors attenuates disease in murine models of IBD. Thus, identifying chemokines and their receptors that are involved in intestinal inflammation provide promising targets for new drug development in the treatment of IBD.
Installation considerations for multi-motor AC drives and filters used in metal industry applications (2002)

This paper investigates the zero sequence current that develops in the ground circuit of a multi-motor drive application. The motivation was to reduce the magnitude of common mode electrical noise in the system ground grid and to reduce occurrence of ground fault sensor trips as a result of this noise. The phenomenon of line to ground cable charging current (I/sub l/g) during drive switching is a main component of zero sequence current and is discussed with basic equations describing its magnitude. Results of a high frequency characterization study of all components in the zero sequence path was required to obtain estimates of surge impedance for these equations. Measured surge impedance was also used in a simulation program designed to predict I/sub lg/ magnitude for various system conditions. A PWM output filter and an input isolation transformer with the neutral high resistance grounded were two solutions investigated to reduce the zero sequence current that were both simulated and measured on site.
Effects of Reflow Processing and Flux Residue on Ionic Migration of Lead-Free Solder Plating Using the Quartz Crystal Microbalance Method (2001)

To investigate the ionic migration, quite a new measurement method has been developed by the authors, which enables real time monitoring of the growth process of ionic migration using a QCM (Quartz Crystal Microbalance). This research has focused on the QCM method to study the growth process of ionic migration in various types of lead-free solder plating and the effects of the reflow processing and flux residue of soldering processes. In addition, we investigated the anode dissolution characteristics of the elements in each type of solder alloy by measuring the current-potential curve in 0.1 kmol m−3 KNO3 solution. When using Sn–3.5 mass%Ag solder plating, reflow processing segregates the stable compound Ag3Sn layer and Sn layer. The Sn layer selectively promotes the anode dissolution reaction, increasing the occurrence of migration. When using Sn–9 mass%Zn solder plating, the Sn effectively prevents the excessive dissolution reaction of Zn. However, since reflow processing causes each element to separate out, reflow processing lessens the effectiveness of Sn, thus promoting the occurrence of migration. The flux processing of lead-free solders suppresses anode dissolution and effectively prevents the occurrence of migration. However, with Sn–9 mass%Zn, the lowered adhesion between the flux film and the electrodes is a factor in speeding the growth of migration.

Solventless reaction dramatically accelerates supramolecular self-assemblyElectronic supplementary information (ESI) available: experimental details and CD spectra. See http://www.rsc.org/suppdata/cc/b2/b203651g/ (2002)

It has been disclosed that the supramolecular self-assembly is dramatically accelerated under solvent-free conditions leading to higher-order fabrications of two- or three-dimensional topology and even double helicates.
Synthesis of Eupalinilide E, a Promoter of Human Hematopoietic Stem and Progenitor Cell Expansion (2016)

Improving the ex vivo and in vivo production of hematopoietic stem and progenitor cells (HSPCs) has the potential to address the short supply of these cells that are used in the treatment of various blood diseases and disorders. Eupalinilide E promotes the expansion of human HSPCs and inhibits subsequent differentiation, leading to increased numbers of clinically useful cells. This natural product represents an important tool to uncover new methods to drive expansion while inhibiting differentiation. However, in the process of examining these effects, which occur through a novel mechanism, the natural product was consumed, which limited additional investigation. To provide renewed and improved access to eupalinilide E, a laboratory synthesis has been developed and is reported herein. The synthetic route can access >400 mg in a single batch, employing reactions conducted on useful scales in a single vessel. Key transformations enabling the approach include a diastereoselective borylative enyne cyclization and a late-stage double allylic C-H oxidation as well as adapted Luche reduction and aluminum-mediated epoxidation reactions to maximize the synthetic efficiency. Retesting of the synthetic eupalinilide E confirmed the compound's ability to expand HSPCs and inhibit differentiation.
Distinct Recirculating and Non-Recirculating B-Lymphocyte Pools in the Peripheral Blood Are Defined by Coordinated Expression of CD21 and L-Selectin (1997)

The continual recirculation of lymphocytes between the blood, tissues, and lymph is essential for the coordination and dissemination of immune responses. We have compared the functional and phenotypic properties of lymphocytes isolated from blood and lymph, the two major migratory populations. Lymph-borne lymphocytes migrated readily into the lymphatic recirculation pathway, but greater than one third of all peripheral blood lymphocytes (PBLs) were excluded from the lymphatic circuit and showed an enhanced migration to the spleen. Phenotypic analysis showed that most non-recirculating PBLs were B cells. The migration competence of B cells correlated with the surface expression of CD21 and L-selectin; recirculating B cells expressed both of these molecules, whereas non-recirculating B cells lacked both antigens. These results establish that blood contains distinct pools of lymphocytes that differ in their recirculation competence. Clearly, blood sampling is not an efficient method to directly measure the status of the recirculating immune system, and implies important constraints and restrictions in the interpretation of experimental or clinical data that include phenotypic and quantitative analyses of blood lymphocytes.
Annual report for FY 1976 on project AN0115A: the migration of plutonium and americium in the lithosphere (1976)

Studies have been carried out on the migration of plutonium and americium in solutions flowing through porous and crushed rock and through fissures. The migration process can be described in terms of the surface absorption of these elements. In addition, chemical effects on the absorption have been observed. One of these effects is possibly due to the presence of a plutonium polymer that migrates at a more rapid rate than normal plutonium.
Glycogen Depletion in Specific Types of Human Skeletal Muscle Fibers in Intermittent and Continous Exercise (1975)

Within the past few years considerable progress has been made toward our understanding of some of the fundamental characteristics of motor units and their muscle fibers. For example, specific metabolic, circulatory and dynamic properties of skeletal muscles of different animals including humans are closely related [2, 4, 5, 8, 19, 21, 23, 24, 28, 32]. In spite of our increasing understanding of these properties we know little about how these different types of motor units are used by an intact animal in normal movements such as walking, running, swimming and jumping [1, 9, 10, 12, 16, 17]. These studies do however provide some evidence of how types of muscle fibers may be used differentially by assessing glycogen. depletion in specific types of muscle fibers.

Health, poverty, and place in Accra, Ghana: mapping neighborhoods (2012)

The overall objective of our research project is to understand the spatial inequality in health in Accra, the capital city of Ghana. We also utilize GIS technology to measure the association of adverse health and mortality outcomes with neighborhood ecology. We approached this in variety of ways, including multivariate analysis of imagery classification and census data. A key element in the research has been to obtain in-person interviews from 3,200 female respondents in the city, and then relate health data obtained from the women to the ecology of the neighborhoods in which they live. Detailed maps are a requirement for these field-based activities. However, commercially available street maps of Accra tend to be highly generalized and not very useful for the kind of health and social science research being undertaken by this project, The purpose of this paper is to describe street maps that were created for the project's office in downtown Accra and used to locate households of respondents. They incorporate satellite imagery with other geographic layers to provide the most important visual interpretation of the linkage between imagery and neighborhoods. Ultimately, through a detailed analysis of spatial disparities in health in Accra, Ghana, we aim to provide a model for the interpretation of urban health inequalities in cities of urbanizing and often poor countries.

A framework for and assessment of demand response and energy storage in power systems (2013)

The shift in the electricity industry from regulated monopolies to competitive markets as well as the widespread introduction of fluctuating renewable energy sources bring new challenges to power systems. Some of these challenges can be mitigated by using demand response (DR) and energy storage to provide power system services. The aim of this paper is to provide a unified framework that allows us to assess different types of DR and energy storage resources and determine which resources are best suited to which services. We focus on four resources: batteries, plug-in electric vehicles, commercial buildings, and thermostatically controlled loads. We define generic power system services in order to assess the resources. The contribution of the paper is threefold: (i) the development of a framework for assessing DR and energy storage resources; (ii) a detailed analysis of the four resources in terms of ability for providing power system services, and (iii) a comparison of the resources, including an example case for Switzerland. We find that the ability of resources to provide power system services varies largely and also depends on the implementation scenario. Generally, there is large potential to use DR and energy storage for providing power system services, but there are also challenges to be addressed, for example, adequate compensation, privacy, guaranteeing costumer service, etc.
Modulation of vascular tone by low density lipoproteins: effects on L‐arginine transport and nitric oxide synthesis (1997)

Low density lipoprotein (LDL) plays an important role in atherogenesis. Focal accumulation within the arterial intima of excess amounts of cholesterol-rich LDL leads to the migration and recruitment of monocytes, which then differentiate into macrophages after taking up large amounts of oxidatively modified LDL via their scavenger receptors and become lipid-laden 'foam cells' within the subendothelial space. It is generally accepted that oxidized LDL and hyperlipidaemia impair endothelial-dependent vascular relaxation, yet the existing literature on the effects of oxidatively modified LDL on endothelium-derived nitric oxide (NO) and prostacyclin (PGI2) release is inconclusive, since oxidized LDL has been reported to enhance or reduce NO and PGI2 production. Our studies using cultured human endothelial and smooth muscle cells have established that basal rates of L-arginine (NO precursor) transport, NO and PGI2 production and soluble guanylyl cyclase activity are unaffected by pretreatment (for 1 or 24 h) with native LDL, or with mildly or highly oxidized LDL. In contrast, highly oxidized LDL inhibited histamine-stimulated release of NO and PGI2 from human endothelial cells and induced an adaptive increase in the level of intracellular glutathione in human smooth muscle cells, a response which was prevented by the chain-breaking antioxidant alpha-tocopherol. Although initial rates of L-arginine transport and basal NO and PGI2 release from human endothelium are unaffected by oxidized LDL, agonist-stimulated release of these vasodilators is markedly attenuated. Elucidation of the mechanisms regulating these responses and their sensitivity to dietary antioxidants could lead to alternative strategies for reducing atherogenesis.

Low-Profile and High-Gain Yagi Wire-Patch Antenna for WiMAX Applications (2012)

This letter presents the design of a low-profile, high-gain Yagi wire-patch antenna array that radiates a directional beam in the azimuthal plane within the frequency band 5.45-5.75 GHz. The elementary unit of a typical Yagi antenna is replaced by wire-patch antenna. This antenna delivers a gain of 14.8 dB at 5.6 GHz. A prototype of this modelized antenna is manufactured, and the measured performances are similar to the simulated ones.
Low-loss high-purity GaAs waveguides for monolithic integrated optical circuits at GaAs laser wavelengths (1976)

Attenuation measurements in epitaxial n-GaAs waveguides of different purity have been made near the absorption edge. These measurements show that losses of less than 2 cm−1 can be achieved at energies within 50 meV of the band edge using material with ND+NA⩽2×1015 cm−3. These loss values are low enough to permit the use of GaAs waveguides in some integrated optical circuits and, in addition, are significantly lower than those published for AlxGa1−xAs waveguides of similar purity at energies comparably near the absorption edge.
Genome Sequence and Analysis of the Oral Bacterium <i>Fusobacterium nucleatum</i> Strain ATCC 25586 (2002)

We present a complete DNA sequence and metabolic analysis of the dominant oral bacterium Fusobacterium nucleatum. Although not considered a major dental pathogen on its own, this anaerobe facilitates the aggregation and establishment of several other species including the dental pathogens Porphyromonas gingivalis and Bacteroides forsythus. The F. nucleatum strain ATCC 25586 genome was assembled from shotgun sequences and analyzed using the ERGO bioinformatics suite (http://www.integratedgenomics.com). The genome contains 2.17 Mb encoding 2,067 open reading frames, organized on a single circular chromosome with 27% GC content. Despite its taxonomic position among the gram-negative bacteria, several features of its core metabolism are similar to that of gram-positive Clostridium spp., Enterococcus spp., and Lactococcus spp. The genome analysis has revealed several key aspects of the pathways of organic acid, amino acid, carbohydrate, and lipid metabolism. Nine very-high-molecular-weight outer membrane proteins are predicted from the sequence, none of which has been reported in the literature. More than 137 transporters for the uptake of a variety of substrates such as peptides, sugars, metal ions, and cofactors have been identified. Biosynthetic pathways exist for only three amino acids: glutamate, aspartate, and asparagine. The remaining amino acids are imported as such or as di- or oligopeptides that are subsequently degraded in the cytoplasm. A principal source of energy appears to be the fermentation of glutamate to butyrate. Additionally, desulfuration of cysteine and methionine yields ammonia, H(2)S, methyl mercaptan, and butyrate, which are capable of arresting fibroblast growth, thus preventing wound healing and aiding penetration of the gingival epithelium. The metabolic capabilities of F. nucleatum revealed by its genome are therefore consistent with its specialized niche in the mouth.
High-frequency operation of surface-acoustic-wave muiltielectrode transducers (1974)

The operation of transducers with more than two electrodes per electrical period is disussed. When two different structures are used for input and output transducers, the frequency responses can be made to overlap at one desired band of frequencies, while reducing other surface-and bulk-wave responses.
Gene Frequencies of Electrophoretically Determined Polymorphisms in Guernsey Blood and Milk (1974)

The milk and blood of 6,787 first lactation Guernsey cows from 78 herds in 11 states were typed for a~a-casein, tcasein, K-casein, fl-laetoglobulin, hemoglobin, and senma transferrin. Milk proteins were typed by polyacrylamide gel electrophoresis at Delaware, hemoglobin and transferrin by slab and disc polyacrylamide gel electrophoresis at Ohio. Gene frequencies were: a~l-casein B .74, a~l-casein C .26; t-casein A1 .011, tcasein A2 .952, t-casein A3 .004, ficasein B .014, t-casein C .019; K-casein A .72, K-casein B .28; fl-lactoglobulin A .38, fi-lactoglobulin B .62; transferrin A .37, transferrin D .62, transferrin E .0002; hemoglobin A .87, hemoglobin B .13. Hardy-Weinberg equilibrium existed in all but the fl-Iactoglobulin system where there were significantly fewer heterozygotes than expected. Two-way and three-way contingency tables indicated nonindependence of ,~l-casein and K-casein, t-casein mad K-casein, ~slcasein and t-casein, and transferrin and hemoglobin.
