Vapor Deposition of Highly Conformal Copper Seed Layers for Plating Through-Silicon Vias (TSVs)
(Electrochemical Society, 2012)Through-silicon vias (TSV) will speed up interconnections between chips. Manufacturable and cost-effective TSVs will allow faster computer systems. In this paper, we report the successful formation of seed layers for plating ... -
VAR2CSA Signatures of High Plasmodium falciparum Parasitemia in the Placenta
(Public Library of Science, 2013)Plasmodium falciparum infected erythrocytes (IE) accumulate in the placenta through the interaction between Duffy-binding like (DBL) domains of parasite-encoded ligand VAR2CSA and chondroitin sulphate-A (CSA) receptor. ... -

Variability and Vulnerability at the Ecological Level: Implications for Understanding the Social Determinants of Health
(American Public Health Association, 2002-11)Objectives. We examined variability in disease rates to gain understanding of the complex interactions between contextual socioeconomic factors and health.Methods. We compared mortality rates between New York and California ... -
Variability Improvement by Interface Passivation and EOT Scaling of InGaAs Nanowire MOSFETs
(Institute of Electrical and Electronics Engineers, 2013)High-performance InGaAs gate-all-around (GAA) nanowire MOSFETs with channel length (\(L_{ch}\)) down to 20 nm are fabricated by integrating a higher-k \(LaAlO_3\)-based gate-stack with an equivalent oxide thickness of ... -
Variability in Blazars: Clues from PKS 2155−304
(Oxford University Press (OUP), 2012)Rapid variability on a time scale much faster than the light-crossing time of the central supermassive black hole has been seen in TeV emission from the blazar PKS 2155-304. The most plausible explanation of this puzzling ... -
Variability in conditioned pain modulation predicts response to NSAID treatment in patients with knee osteoarthritis
(BioMed Central, 2016)Background: Patients with painful knee osteoarthritis (OA) demonstrate hyperalgesia and altered pain-modulatory responses. While some prior work has demonstrated cross-sectional associations between laboratory and clinical ... -
Variability in MRI vs. ultrasound measures of prostate volume and its impact on treatment recommendations for favorable-risk prostate cancer patients: a case series
(BioMed Central, 2014)Background: Prostate volume can affect whether patients qualify for brachytherapy (desired size ≥20 mL and ≤60 mL) and/or active surveillance (desired PSA density ≤0.15 for very low risk disease). This study examines ... -
Variability in strength of red yeast rice supplements purchased from mainstream retailers
(SAGE Publications, 2017-06-23)The United States Food and Drug Administration (FDA) has introduced manufacturing standards for dietary supple- ments, including red yeast rice, to assure their identity, purity, strength, and composition. One supplement ... -
Variability in surface ozone background over the United States: Implications for air quality policy
(Wiley-Blackwell, 2003)The U.S. Environmental Protection Agency (EPA) presently uses a 40 ppbv background O3 level as a baseline in its O3 risk assessments. This background is defined as those concentrations that would exist in the absence of ... -
Variability in the Perception of Informed Consent for IV-tPA during Telestroke Consultation
(Frontiers Research Foundation, 2012)Objective: To study the perception of informed consent among various raters for thrombolysis in acute ischemic stroke patients receiving intravenous tissue plasminogen activator (IV-tPA). Methods: Twenty randomly selected ... -
Variability in the Quality of Visual Working Memory
(Nature Publishing Group, 2012)Working memory is a mental storage system that keeps task-relevant information accessible for a brief span of time, and it is strikingly limited. Its limits differ substantially across people but are assumed to be fixed ... -
Variability in thermal and phototactic preferences in Drosophila may reflect an adaptive bet‐hedging strategy
(John Wiley and Sons Inc., 2015)Organisms use various strategies to cope with fluctuating environmental conditions. In diversified bet‐hedging, a single genotype exhibits phenotypic heterogeneity with the expectation that some individuals will survive ... -
Variability in Tuberculosis Granuloma T Cell Responses Exists, but a Balance of Pro- and Anti-inflammatory Cytokines Is Associated with Sterilization
(Public Library of Science, 2015)Lung granulomas are the pathologic hallmark of tuberculosis (TB). T cells are a major cellular component of TB lung granulomas and are known to play an important role in containment of Mycobacterium tuberculosis (Mtb) ... -
Variability of Cometary X-Ray Emission Induced by Solar Wind Ions
(American Astronomical Society, 2001)X-ray emission spectra induced by the interaction of the slow and fast solar wind components with cometary gas are calculated for typical solar wind compositions. The emission spectra arising from the charge transfer ... -
Variability of Gamma‐Ray Burst Afterglows due to Interstellar Turbulence
(American Astronomical Society, 2000)Gamma-ray burst (GRB) afterglows are commonly interpreted as synchrotron emission from a relativistic blast wave produced by a point explosion in an ambient medium, plausibly the interstellar medium of galaxies. We calculate ... -
Variability of NGC 4051 and the nature of narrow-line Seyfert 1 galaxies
(Elsevier BV, 2000)We report on a three-year program of coordinated X-ray and optical monitoring of the Narrow-Line Seyfert 1 galaxy NGC 4051. The rapid continuum variations observed in the X-ray spectra are not detected in the optical, ... -
The variability of the spectrum of Arakelian 120. II - Evidence for a small broad line emitting region
(IOP Publishing, 1985)The results of four years of spectroscopic and photometric observations of the Seyfert galaxy Akn 120 are reported. The observations were carried out using the image dissector scanner attached to the Perkins 1.8-meter ...
