Trans-rectal ultrasound-coupled near-infrared optical tomography of the prostate. Part I: Simulation
(Optica Publishing Group, 2008-10-15)
We investigate the feasibility of trans-rectal optical tomography of the prostate using an endo-rectal near-infrared (NIR) applicator that is to be integrated with a trans-rectal ultrasound (TRUS) probe. Integration with ...
Arsenic-induced changes in the gene expression of lung epithelial L2 cells: Implications in carcinogenesis
(BioMed Central, 2008-03-03)
Background: Arsenic is a carcinogen that is known to induce cell transformation and tumor formation. Although studies have been performed to examine the modulation of signaling molecules caused by arsenic exposure, the ...
Prevalence and genotypes of Anaplasma species and habitat suitability for ticks in a Mediterranean ecosystem
(American Society for Microbiology, 2008-12)
Anaplasma species are tick-transmitted pathogens that impact veterinary and human health. Sicily is one of the locations where these pathogens are endemic. Sicily represents a typical Mediterranean ecosystem to study ...
Nonclassical correlation of polarization-entangled photons in a biexciton-exciton cascade
(IOP Publishing, 2008-11-07)
We develop a theoretical model to study the intensity–intensity correlation of polarization-entangled photons emitted in a biexciton–exciton cascade. We calculate the degree of correlation and show how polarization ...
Electromagnetic field induced modification of branching ratios for emission in structured vacuum
(IOP Publishing, 2008-01-17)
We report a fundamental effect of the electromagnetic field induced modification of the branching ratios for emission into several final states. The modifications are especially significant if the vacuum into which the ...
Resonant terahertz transmission in plasmonic arrays of subwavelength holes
(EDP Sciences, 2008-07-04)
A review of transmission properties of two-dimensional plasmonic structures in the terahertz regime is presented. Resonant terahertz transmission was demonstrated in arrays of subwavelength holes patterned on both metals ...
Underlying terahertz vibrational spectrum of explosives solids
(AIP Publishing, 2008-07-08)
Using waveguide terahertz time-domain spectroscopy, we demonstrate the measurement of the underlying terahertz vibrational spectrum of the explosive solids hexahydro-1,3,5-trinitro-1,3,5-triazine, and 2,4,6-trinitrotoluene. ...
Analysis of the enacted curriculum for the Oklahoma State Department of Education for the collection period February – March, 2008
(The Standards Company LLC, 2008-10-17)
As part of a 120-school, statewide curriculum analysis project contracted by the Oklahoma State Department
of Education, The Standards Company LLC used its RubyTM curriculum analysis service to perform a statistical
study ...
Exploitation and destabilization of a warm, freshwater ecosystem through engineered hydrological change
(Ecological Society of America, 2008)
Exploitation of freshwater resources is having catastrophic effects on the ecological dynamics, stability, and quality of those water resources on a global scale, especially in arid and semiarid regions. Lake Kinneret, ...
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 ...
