Direct optoelectronic generation and detection of sub-ps-electrical pulses on sub-mm-coaxial transmission lines
(AIP Publishing, 2004-12-20)
We report efficient direct optoelectronic generation of sub-ps-THz pulses on 50 Ohm coaxial transmission lines with a 330 micro-m diameter solid copper outer tube filled with Teflon containing the 80 micro-m diameter inner ...
Direct observation of the Gouy phase shift in THz impulse ranging
(AIP Publishing, 2000-02-07)
Here we present a direct observation of the Gouy effect through THz impulse scattering from cylindrical and spherical targets. A pi/2 Gouy phase shift through a one-axis focus compared to the more common pi phase shift of ...
Evidence for WZ and ZZ production in final states with b-tagged jets
(2011-11-15)
We present evidence for the combined production of VZ (V = W or Z) events in final states containing charged leptons (electrons or muons) or neutrinos, and heavy flavor jets, using data collected by the D0 detector at the ...

Sex specific expression and distribution of small RNAs in papaya
(BioMed Central, 2014-01-13)
Background: Regulatory function of small non-coding RNAs (sRNA) in response to environmental and developmental cues has been established. Additionally, sRNA, also plays an important role in maintaining the heterochromatin ...
Effects of dietary energy and starch concentrations for newly received feedlot calves: I. Growth performance and health
(American Society of Animal Science, 2004)
Crossbred calves (n = 572; initial BW = 186 +/= 27 kg) purchased from northern Texas, Arkansas, and southeast Oklahoma auction markets were delivered to the Willard Sparks Beef Research Center, Stillwater, OK, and used to ...
Broccoli (Brassica oleracea) phloem tissue proteome
(BioMed Central, 2013-11-07)
Background: The transport of sugars, hormones, amino acids, proteins, sugar alcohols, and other organic compounds from the sites of synthesis to the sites of use or storage occurs through the conducting cells of the phloem. ...
Crystal structure of Bacillus anthracis dihydrofolate reductase with the dihydrophthalazine-based trimethoprim derivative RAB1 provides a structural explanation of potency and selectivity
(American Society for Microbiology, 2009-07)
Bacillus anthracis possesses an innate resistance to the antibiotic trimethoprim due to poor binding to dihydrofolate reductase (DHFR); currently, there are no commercial antibacterials that target this enzyme in B. ...
Development of a rickettsia isolated from an aborted bovine fetus
(American Society for Microbiology, 1990-10)
An obligate intracellular rickettsial organism isolated from an aborted bovine fetus was studied in bovine turbinate and mouse macrophage cell cultures with light and electron microscopy. Development of the organism was ...
Application of the transtheoretical model to sedentary behaviors and its association with physical activity status
(Public Library of Science (PLoS), 2017-04-27)
Background: The Transtheoretical Model (TTM) is a successful framework for guiding behavior change programs for several health behaviors, yet its application to reduce of sedentary behavior has been neglected. In addition, ...
