A Data Model for Heterogeneous Data Sources (2008)

The information has been and still is a significant factor supporting decision making. In E-Business, distributed information needs to be integrated or inter operated to provide the unique view of information from disparate sources. The integration of data sources when the relevant databases have been designed dependently does not create heterogeneity problems. However, when databases have been designed independently, there are heterogeneity problems such as different terminology, data types, units of measurement, domains, scopes, and so on. Heterogeneous data integration requires a data model which is capable of describing data, schemas and contexts. This complexity suggests the need for a new data model having characteristics appropriate for supporting a mediated approach for the integration of databases and legacy systems. This paper presents the Mediated Data Model (MDM), a data model which is designed for describing data, schemas and contexts in the mediated approach for the integration of database and legacy systems. Its main feature is its ability to describe or represent heterogeneous data both schematically and semantically.
Structure, magnetic property, and spin polarization of Co2FeAlxSi1−x Heusler alloys (2007)

We report the spin polarization of Co2FeAlxSi1−x (x=0.0, 0.3, 0.5, 0.7) bulk alloys measured by the point contact Andreev reflection method. All the Co2FeAlxSi1−x alloys had an L21 structure along with A2- and B2-type disorder. Several off-stoichiometric alloys (CoxFeyAl0.5Si0.5) were prepared to understand the effect of the compositional deviation from the stoichiometry on the spin polarization. By substituting Al for Si, the spin polarization changed from 0.57±0.01 for x=0.0 to a maximum value of 0.60±0.01 for x=0.5. The off-stoichiometric alloys had spin polarizations of 0.57−0.60±0.01. Ab initio calculations were performed to interpret the effect of Al addition as well as the effect of disorder on the magnetic properties and on the electronic structure.
The Role of the Tubulointerstitium in Radiation-Induced Renal Fibrosis (2001)

The functional and morphological response of the remaining hypertrophied kidney in unilaterally nephrectomized rats to single doses of 0-20 Gy X rays was investigated. Functional and histological end points were assessed serially 4-24 weeks postirradiation. Renal irradiation led to time- and dose-dependent reductions in renal function, seen in terms of a decreased glomerular filtration rate, increased blood urea nitrogen, and reduced hematocrit. These changes were accompanied by morphological changes in the glomerular, tubular and interstitial portions of the kidney. However, dose-dependent changes were observed only in terms of tubulointerstitial lesions. Significant increases in the degree of interstitial staining for collagen type III and fibronectin were observed 24 weeks postirradiation. These increases in extracellular matrix components were accompanied by a significant increase in interstitial alpha smooth muscle actin, suggesting activation of interstitial fibroblasts into myofibroblasts. There was no evidence of glomerular Tgfb after renal irradiation. A significant increase in tubular Tgfb staining was only seen 8 weeks postirradiation. In contrast, there was a shift of staining to the interstitium such that by 24 weeks postirradiation interstitial Tgfb staining was significantly greater than that seen in controls. These findings suggest that the tubule epithelial cell and the interstitial fibroblast are both active participants in the development and/or progression of radiation-induced renal fibrosis.
Patellofemoral joint: kinematic MR imaging to assess tracking abnormalities. (1988)

The patellofemoral joint was imaged with magnetic resonance (MR) in the axial plane while the knee was positioned from 0 degrees to 32 degrees of flexion (nine positions). These multiple sequential images obtained within the early phases of flexion of the knee were viewed in a "cine-loop" format, producing a kinematic study that clearly demonstrated the relationship of the patella to the trochlear groove. Four healthy subjects and one patient with known bilateral subluxing patellae were studied. The preliminary results suggest that kinematic MR imaging of the patellofemoral joint is potentially useful for the evaluation of patellar tracking abnormalities.

Bacteremia caused by hemolytic, high-level gentamicin-resistant Enterococcus faecalis (1991)

Between 1 January 1984 and 31 December 1987, 206 enterococcal blood isolates at the University of Wisconsin Hospital and Clinics were analyzed for high-level aminoglycoside resistance (hereafter high-level aminoglycoside resistance is simply referred to as "resistance") and hemolysin production. Of 190 Enterococcus faecalis isolates, 68 (35.8%) were resistant to gentamicin. Of these 68 strains, 67 (98.5%) contained a gene coding for the bifunctional aminoglycoside-modifying 6'-aminoglycoside acetyltransferase-2"-aminoglycoside phosphotransferase [AAC(6')-APH(2")] enzyme. Of 190 isolates, 85 (44.7%) were hemolytic and contained a gene coding for component A of the enterococcal hemolysin. Sixty-two of 68 (91.2%) gentamicin-resistant isolates but only 23 of 122 (18.8%) gentamicin-susceptible isolates were hemolytic (P less than 0.001). Twelve of the hemolytic, gentamicin-resistant E. faecalis blood isolates, but only 2 of 9 nonhemolytic or gentamicin-susceptible isolates, had identical chromosomal DNA restriction endonuclease digestion patterns, suggesting a common derivation for these strains. A historical cohort study from 1 July 1985 to 31 March 1987 identified by regression analysis postsurgical intensive care unit status (odds ratio [OR], 5.0; 95% confidence interval [CI], 1.1 to 22.8) and prior treatment with an expanded- or broad-spectrum cephalosporin (OR, 3.0; 95% CI, 0.9 to 10.1) as risk factors for gentamicin-resistant E. faecalis bacteremia. Patients with hemolytic, gentamicin-resistant E. faecalis bacteremia had a fivefold-increased risk for death within 3 weeks of their bacteremia compared with patients with nonhemolytic, gentamicin-susceptible strains (95% CI, 1.0 to 25.4).
Dehalogenation of Chlorinated Ethenes and Immobilization of Nickel in Anaerobic Sediment Columns under Sulfidogenic Conditions (2002)

A sediment column study was carried out to demonstrate the bioremediation of chloroethene- and nickel-contaminated sediment in a single anaerobic step under sulfate-reducing conditions. Four columns (one untreated control column and three experimental columns) with sediment from a chloroethene- and nickel-contaminated site were investigated for 1 year applying different treatments. By stimulating the activity of sulfate-reducing bacteria by the addition of sulfate as supplementary electron acceptor, complex anaerobic communities were maintained with lactate as electron donor (with or without methanol), which achieved complete dehalogenation of tetra- and trichloroethenes (PCE and TCE) to ethene and ethane. A few weeks after sulfate addition, production of sulfide increased, indicating an increasing activity of sulfate-reducing bacteria. The nickel concentration in the effluent of one nickel-spiked column was greatly reduced, likely due to the enhanced sulfide production, causing precipitation of nickel sulfide. At the end of the study, 94% of the initial amount of nickel added to that column was recovered in the sediment As compared to the untreated (nonspiked) control column, all chloroethene-spiked columns ladditions of PCE and TCE) showed a permanent release of small chloride ion quantities (approximately 0.5-0.7 mM chloride), which were detected in the effluents a few weeks after sulfide production was observed for the first time. The formation of ethene and ethane as final products after dechlorination of PCE and TCE was detected in some effluents and in some gas phases of the columns. Other metabolites or intermediates (such as DCE isomers) were only detected sporadically in negligible quantities. The results of this study demonstrated thatmicrobial activity stimulated under sulfate-reducing conditions can have a beneficial effect on both the precipitation of heavy metals and the complete dechlorination of organochlorines. The strongly negative redox potential created by the activity of sulfate-reducing bacteria may be one factor responsible for stimulating the activity of the dehalogenating bacteria in the test columns.
Corybantic (2013)

Software-Defined Networking (SDN) promises to enable vigorous innovation, through separation of the control plane from the data plane, and to enable novel forms of network management, through a controller that uses a global view to make globally-valid decisions. The design of SDN controllers creates novel challenges; much previous work has focused on making them scalable, reliable, and efficient.
Protection of Petroleum Pipeline Carbon Steel Alloys with New Modified Core‐Shell Magnetite Nanogel against Corrosion in Acidic Medium (2013)

New method was used to prepare magnetite nanoparticle based on reduction of Fe(III) ions with potassium iodide to produce Fe 3 O 4 nanoparticle. The prepared magnetite was stabilized with cross‐linked polymer based on 2‐acrylamido‐2‐methylpropane sulfonic acid (AMPS to prepare novel core‐shell nanogel. In this respect, Fe 3 O 4 /poly(2‐acrylamido‐2‐methylpropane sulfonic acid) (PAMPS) magnetic nanogels with controllable particle size produced via free aqueous polymerization at 65°C have been developed for the first time. The polymer was crosslinked in the presence of N,N‐methylenebisacrylamide (MBA) as a crosslinker and potassium peroxydisulfate (KPS) as redox initiator system. The structure and morphology of the magnetic nanogel were characterized by Fourier transform infrared spectroscopy (FTIR) and transmission and scanning electron microscopy (TEM and SEM). The effectiveness of the synthesized compounds as corrosion inhibitors for carbon steel in 1 M HCl was investigated by various electrochemical techniques such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The results showed enhancement in inhibition efficiencies with increasing the inhibitor concentrations. The results showed that the nanogel particles act as mixed inhibitors. EIS data revealed that R ct increases with increasing inhibitor concentration.
Tumor size does not limit radiation‐inducible gene therapy in a human xenograft model (1995)

Abstract Tumor size has been reported to be a limiting factor in both radiotherapy (RT) and gene therapy. Therefore, we assessed the effects of tumor necrosis factor‐alpha (TNF‐α) gene therapy and radiation in relatively large tumors in a human xenograft system. We linked DNA sequences from the promoter region of the radiation‐inducible gene Egr‐1 to the cDNA sequence that encodes human TNF‐α, a radiosensitizing cytokine. The Egr‐TNF construct was transfected into the human hematopoietic cell line HL525. Stable transfectants, exhibiting radiation inducibility of TNF‐α in vitro (clone 2 cells), were directly injected into xenografts of a radioresistant human squamous cell carcinoma cell line, SQ‐20B. In a previous study, 100 mm 3 tumors treated with radiation and clone 2 cells demonstrated significant tumor control ( P < 0.0001) when compared with tumors treated with clone 2 alone or radiation alone. In the present study, 450 mm 3 xenografts treated with clone 2 cells and radiation were significantly smaller ( P < 0.01) at the nadir of regression than tumors treated with radiation alone. Because the radiation dose was held constant (40 Gy) in both 100 and 450 mm 3 xenografts, only one cure was noted in the larger tumors. These data support an interactive anti‐tumor effect in vivo between radiation and TNF‐α gene therapy which is equal in both small and large human tumor xenograft models. © 1995 Wiley‐Liss, Inc.
Clustering based simulated annealing for standard cell placement (1988)

Simulated annealing has been shown to be effective in producing good quality results for the standard cell placement problem. Its main drawback is the excessive computation time required, which increases significantly with the problem size. In this paper we present a novel technique for reducing the effective problem size for simulated annealing without compromising the solution quality. We form clusters of cells based on their interconnections, and place them first using conventional simulated annealing. We then break up the clusters, and place the individual cells using another simulated annealing process that does a refinement on the placement. The original problem is thus divided into two subproblems, each requiring much less time. The results with this 2-stage simulated annealing have been superior to those with our conventional simulated annealing implementation, with more significant improvements observed for larger chips. For chips with more than 2500 cells, we have observed a factor of 2 to 3 speed-up in CPU time, together with a 6 to 17% improvement in the estimated wire-length.

Long-lived complexes between peptide and class II major histocompatibility complex are formed at low pH with no requirement for pH neutralization. (1992)

The binding of peptide antigens to class II histocompatibility glycoproteins can be markedly enhanced at pH values approximating those found in acidic endosomal compartments in antigen-presenting cells (APC). It has been proposed by others that low pH may increase the conformational flexibility of class II, facilitating both the association and dissociation of peptides. Neutralization of pH, as class II is expressed on the plasma membrane of APC, could then serve to trap peptide in a stable complex. If this were the only mechanism accounting for enhanced peptide binding at low pH, one would predict that there should be a concordance between the pH conditions required for enhanced binding and those associated with increased peptide dissociation. Furthermore, long-lived complexes of class II and peptide should not be observed at low pH without neutralization. In the present communization, I provide the data that support the generality of my previous conclusion that both affinity and maximal binding are regulated by pH in experiments using purified class II and biotin-labeled peptides. The pH profile for binding and dissociation using three different class II glycoproteins was analyzed, and the results demonstrated that enhanced binding is not coupled to enhanced dissociation. Peptide complexes were observed to be quite stable at pH 4.5 and above. This result was further substantiated in experiments where biotin-peptide/class II complexes were extensively dialyzed at low pH followed by analysis on Western blots probed with avidin. Finally, a low pH assay system was devised to analyze the formation of stable peptide/class II complexes without pH neutralization. Our results indicate that stable complexes can be formed at low pH without the requirement for a shift to neutral pH.
Nearly dispersion-penalty-free transmission using blue-shifted 1.55- mu m distributed feedback lasers (1990)

Nearly dispersion-penalty-free transmission over 40 km of nondispersion-shifted single-mode fiber was demonstrated using blue-shifted 1.55- mu m distributed feedback lasers. This good system performance is attributed to the narrow and blue-shifted modulated optical spectrum which is in turn associated with the soft turn-on light-current characteristics. Transmission experiments using lasers with hard turn-on light-current characteristics give rise to broad modulated spectra and higher dispersion penalties.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A conserved RGD (Arg-Gly-Asp) motif in the transferrin receptor is required for binding to transferrin (1999)

The transferrin receptor contains a highly conserved Arg-Gly-Asp (RGD) sequence in the C-terminal region where transferrin is thought to bind. RGD sequences are commonly involved in cell adhesion. This sequence is crucial for transferrin binding, suggesting possible evolutionary links between molecules mediating iron uptake and cell adhesion.
Defect-Location Identification for Cell-Aware Test (2019)

Cell-aware test (CAT) explicitly targets defects inside library cells and therefore significantly reduces the amount of test escapes compared to conventional automatic test pattern generation (ATPG). Our CAT flow consists of three steps: (1) defect-location identification (DLI), (2) defect characterization based on detailed analog simulation of the cells, and (3) cell-aware automatic test pattern generation (ATPG). This paper focuses on Step 1, as quality and cost are determined by the set of cell-internal defect locations considered in the remainder of the flow. Based on technology inputs from the user and a parasitic extraction (PEX) run that analyzes the cell layouts, we derive a set of open defects on and short defects between both transistor terminals and intra-cell interconnects. The full set of defect locations is stored for later use during failure analysis. Through dedicated DLI algorithms, we identify a compact subset of defect locations for defect characterization and ATPG, in which we include only one representative defect location for each set of equivalent defects locations. For Cadence's GPDK045 library, the compact subset contains only 2.8% of the full set of defect locations and reduces the time required for defect characterization with the same ratio.
Comparison of statistical methods commonly used in predictive modelling (2004)

Abstract Logistic Multiple Regression, Principal Component Regression and Classification and Regression Tree Analysis (CART), commonly used in ecological modelling using GIS, are compared with a relatively new statistical technique, Multivariate Adaptive Regression Splines (MARS), to test their accuracy, reliability, implementation within GIS and ease of use. All were applied to the same two data sets, covering a wide range of conditions common in predictive modelling, namely geographical range, scale, nature of the predictors and sampling method. We ran two series of analyses to verify if model validation by an independent data set was required or cross-validation on a learning data set sufficed. Results show that validation by independent data sets is needed. Model accuracy was evaluated using the area under Receiver Operating Characteristics curve (AUC). This measure was used because it summarizes performance across all possible thresholds, and is independent of balance between classes. MARS and Regression Tree Analysis achieved the best prediction success, although the CART model was difficult to use for cartographic purposes due to the high model complexity. Abbreviations: AUC = Area under the ROC curve; CART = Classification Regression Trees; FN = False negative; FP = False positive; GAM = Generalized Additive Model; GIS = Geographic Information System; GLM = Generalized Linear Model; LMR = Logistic Multiple Regression; MARS = Multivariate Adaptive Regression Splines; NDVI = Normalized Difference Vegetation Index; PCR = Principal Components Regression; ROC = Receiver Operating Characteristics.
Seasonal H1N1 Influenza Virus Infection Induces Cross-Protective Pandemic H1N1 Virus Immunity through a CD8-Independent, B Cell-Dependent Mechanism (2011)

During the 2009 H1N1 influenza virus pandemic (pdmH1N1) outbreak, it was found that most individuals lacked antibodies against the new pdmH1N1 virus, and only the elderly showed anti-hemagglutinin (anti-HA) antibodies that were cross-reactive with the new strains. Different studies have demonstrated that prior contact with the virus can confer protection against strains with some degree of dissimilarity; however, this has not been sufficiently explored within the context of a pdmH1N1 virus infection. In this study, we have found that a first infection with the A/Brisbane/59/2007 virus strain confers heterologous protection in ferrets and mice against a subsequent pdmH1N1 (A/Mexico/4108/2009) virus infection through a cross-reactive but non-neutralizing antibody mechanism. Heterologous immunity is abrogated in B cell-deficient mice but maintained in CD8(-/-) and perforin-1(-/-) mice. We identified cross-reactive antibodies from A/Brisbane/59/2007 sera that recognize non-HA epitopes in pdmH1N1 virus. Passive serum transfer showed that cross-reactive sH1N1-induced antibodies conferred protection in naive recipient mice during pdmH1N1 virus challenge. The presence or absence of anti-HA antibodies, therefore, is not the sole indicator of the effectiveness of protective cross-reactive antibody immunity. Measurement of additional antibody repertoires targeting the non-HA antigens of influenza virus should be taken into consideration in assessing protection and immunization strategies. We propose that preexisting cross-protective non-HA antibody immunity may have had an overall protective effect during the 2009 pdmH1N1 outbreak, thereby reducing disease severity in human infections.
Raman spectra for characterization of defective CVD multi‐walled carbon nanotubes (2014)

Curved graphene fragments can be considered as building blocks of carbon nanotubes. Thus, the size of graphene fragments may be considered as one of the most important characteristics of their structural disorder. In this paper, we have performed a comparative Raman study of CVD multi‐walled carbon nanotubes (MWCNTs) and graphene flakes deposited on MWCNTs. Raman data have been considered in combination with HRTEM characterization of nanotubes. The basic attention has been paid to the behavior of D (disorder‐induced), G (tangential mode), and 2D (two‐phonon scattering) bands in Raman spectra in order to use them for MWCNT characterization. A ratio of intensities of 2D and D bands ( I 2D / I D ) demonstrates almost a linear dependence on the mean diameter of MWCNTs produced with two different types of catalysts (see abstract figure). It should be mentioned that each type of catalyst provides the linear dependence with its own specific slope. The graphene fragments have been proposed to form a mosaic structure of nanotube walls. I 2D / I D ratio depends on the amount of graphene flakes deposited on nanotube surface via ethylene decomposition. A dependence of intensity ratio I 2D / I D on the diameter of nanotubes produced with different types of catalysts.
Soft Articulated Characters with Fast Contact Handling (2007)

Abstract Fast contact handling of soft articulated characters is a computationally challenging problem, in part due to complex interplay between skeletal and surface deformation. We present a fast, novel algorithm based on a layered representation for articulated bodies that enables physically‐plausible simulation of animated characters with a high‐resolution deformable skin in real time. Our algorithm gracefully captures the dynamic skeleton‐skin interplay through a novel formulation of elastic deformation in the pose space of the skinned surface. The algorithm also overcomes the computational challenges by robustly decoupling skeleton and skin computations using careful approximations of Schur complements, and efficiently performing collision queries by exploiting the layered representation. With this approach, we can simultaneously handle large contact areas, produce rich surface deformations, and capture the collision response of a character/s skeleton.
