Gerald E. Marti, William G. Stetler-Stevenson, Fatima Abbasi, Gregory A. Jasper, Robert J. Kreitman, Lili Wang
… (n = 105) CD4 value of 40,330 (CV = 8.4%) (p < 0 .05). Consistent differences in CD4 ABC based upon antibody … obtained with the lyse (NH4Cl )/stain method (45,562, 3.7% CV) were lower than those obtained with the stain/lyse …

Elastic Stiffnesses and Internal Frictions of Monocrystal Quartz

October 16, 2008
Author(s)
H M. Ledbetter, Sudook A. Kim, M Lei
Using acoustic-resonance spectroscopy (with only two point contacts with the specimen), we measured both the real and imaginary parts of the elastic-stiffness tensor C ij of a cultured quartz monocrystal. With trigonal symmetry (32 point group, P3 12 space

Suppression of Cup-Burner Flames Using Carbon Dioxide in Microgravity

April 1, 2004
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

Extinction Characteristics of Cup-Burner Flame in Microgravity

V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

In Situ Characterization of Catalytic Propylene Oxidation on the Pt (111) Surface

January 17, 2000
Author(s)
A M. Gabelnick, A T. Capitano, D J. Burnett, Daniel A. Fischer, J L. Gland
The catalytic oxidation of propylene with both propylene and oxygen in the gas phase has been characterized on the Pt(111) surface. In situ soft x-ray kinetic and spectroscopic measurements using fluorescence detection have been used to characterize this

Reduced Gravity Combustion of Thermoplastic Spheres

January 1, 2000

… alloy wire. The total initial pressure varied from 0.05 MPa to 0.15 MPa whereas the ambient oxygen concentration …

Deep Learning for MPC Extraction and False Detection

May 28, 2025
Author(s)
Howard Dai, Jack Chuang, Jian Wang, Samuel Berweger, David Griffith
Multipath component (MPC) extraction is critical for channel modeling and joint communications and sensing (JCAS). The super-resolution algorithm known as CLEAN-Space-Alternating Generalized Expectation (CLEANSAGE) is widely used for MPC extraction

Laser-assisted atom probe tomography of c-plane and m-plane InGaN test structures

April 29, 2022
Author(s)
Norman A. Sanford, Paul T. Blanchard, Alexana Roshko, Ashwin Rishinaramangalam, Daniel Feezell, Albert Davydov
Laser-assisted atom probe tomography (L-APT) was used to measure the indium mole fraction x of c-plane, MOCVD-grown, GaN/InxGa1-xN/GaN test structures and the results were compared with Rutherford backscattering analysis (RBS). Four separate sample types

Technology Development and Field Monitoring in nZEB

Vance (Wm.) Payne, Brian P. Dougherty
… Maryland USA. The first heat pump was a two-stage, 7 kW (2 ton), 15.8 seasonal energy efficiency ratio (SEER), 9.05 heating seasonal performance ratio (HSPF) conventionally …

The DNA Damaging Potential of Photoactivated P25 Titanium Dioxide Nanoparticles

September 30, 2014
Author(s)
Elijah Petersen, Vytas Reipa, Stephanie S. Watson, Deborah Jacobs, Savelas A. Rabb, Bryant C. Nelson
Titanium dioxide nanoparticles (TiO2 NPs) are found in numerous commercial and personal care products. Thus, it is necessary to understand and characterize their potential environmental health and safety risks. It is well known that photoactivated TiO2 NPs

Development and Evaluation of a Candidate Reference Measurement Procedure for the Determination of Progesterone in Human Serum Using Isotope-Dilution Liquid Chromatography-Tandem Mass Spectrometry

September 1, 2006
Author(s)
Susan S. Tai, Bei Xu, Michael J. Welch
Progesterone is a steroid hormone that is involved in regulating female reproductive processes. Its concentration in blood is measured to determine ovarian function. A candidate reference measurement procedure for progesterone in human serum involving
