Tick acquisition of Ehrlichia canis from dogs treated with doxycycline hyclate
(American Society for Microbiology, 2007-09)
Doxycycline generally alleviates clinical monocytic ehrlichiosis, but its efficacy in the control of monocytotropic ehrlichial pathogens requires further investigation. In this study, Ehrlichia canis was detected in dogs ...
High Q, one-dimensional terahertz photonic waveguides
(AIP Publishing, 2007-02-28)
A one-dimensional (1D) photonic metal parallel plate waveguide is presented in the spectral range of 0.5-3 THz that has high throughput and stop bands with up to the experimental limit of 40 dB of dynamic range. By ...
In vivo trans-rectal ultrasound-coupled near-infrared optical tomography of intact normal canine prostate
(World Scientific Publishing, 2009-07-01)
This is the first tomography-presentation of the optical properties of a normal canine prostate, in vivo, in its native intact environment in the pelvic canal. The imaging was performed by trans-rectal near-infrared (NIR) ...
Characterization of thin polymer films using terahertz time-domain interferometry
(AIP Publishing, 2001-08-06)
An interferometer for broadband single-cycle THz pulses is developed based on the Michelson configuration. Total internal reflection of THz pulses in high-resistivity silicon prisms provides a nearly 180° phase shift of ...
Assessment of codivergence of Mastreviruses with their plant hosts
(BioMed Central, 2008-12-18)
Background: Viruses that have spent most of their evolutionary time associated with a single host lineage should have sequences that reflect codivergence of virus and host. Several examples for RNA viruses of host-virus ...
Digital signal processor-based real-time optical Doppler tomography system
(SPIE, the international society for optics and photonics, 2004-05-01)
We present a real-time data-processing and display unit, based on a custom-designed digital signal processor (DSP) module for imaging tissue structure and Doppler blood flow. The DSP module is incorporated into a conventional ...
Quantum random walk of the field in an externally driven cavity
(American Physical Society, 2005-09-16)
Using a resonant interaction between atoms and the field in a high-quality cavity, we show how to realize quantum random walks as proposed by Aharonov et al. [Phys. Rev. A 48, 1687 (1993)]. The atoms are driven strongly ...
Development of an in-situ system and analysis procedure for measuring ground thermal properties
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2000)
Determination of the ground’s thermal conductivity is a significant challenge facing designers of Ground Source Heat Pump (GSHP) systems applied in commercial buildings. The number of boreholes and the depth and cost of ...
inlA premature stop codons are common among Listeria monocytogenes isolates from foods and yield virulence-attenuated strains that confer protection against fully virulent strains
(American Society for Microbiology, 2008-11)
Previous studies showed that a considerable proportion of Listeria monocytogenes isolates obtained from foods carry a premature stop codon (PMSC) mutation in inlA that leads to production of a truncated and secreted InlA. ...
THz Sommerfeld wave propagation on a single metal wire
(AIP Publishing, 2005-04-12)
We report an experimental and theoretical study of THz Sommerfeld wave propagation on a single copper wire. THz pulses are optoelectronically generated and launched onto 0.52-mm-diam copper wire, and the guided THz pulses ...
