Infection of semen-producing organs by SIV during the acute and chronic stages of the disease.
BACKGROUND: Although indirect evidence suggests the male genital tract as a possible source of persistent HIV shedding in semen during antiretroviral therapy, this phenomenon is poorly understood due to the difficulty of sampling semen-producing organs in HIV+ asymptomatic […]
Small-bodied humans from Palau, Micronesia.
Newly discovered fossil assemblages of small bodied Homo sapiens from Palau, Micronesia possess characters thought to be taxonomically primitive for the genus Homo. BACKGROUND: Recent surface collection and test excavation in limestone caves in the rock islands of Palau, Micronesia, has produced a sizeable sample of human skeletal […]
A novel high-capacity ion trap-quadrupole tandem mass spectrometer.
We describe a prototype tandem mass spectrometer that is designed to increase the efficiency of linked-scan analyses by >100-fold over conventional linked-scan instruments. The key element of the mass spectrometer is a novel high ion capacity ion trap, combined in tandem configuration with a quadrupole […]
Child mental representations of attachment when mothers are traumatized: The relationship of family-drawings to story-stem completion.
This study examines the relationship between child play-narratives and family drawings by children of violence-exposed mothers with posttraumatic stress disorder (PTSD). The Family Attachment Drawing Task (FAD-T) and MacArthur Story Stem Battery (MSSB) were administered. Of the […]
Turbulence-induced square-root broadening of the Raman fiber laser output spectrum.
The output characteristics of the conventional one-stage Raman fiber laser (RFL) are described in an optical wave turbulence formalism. Simple analytical expressions describing RFL output power and its spectral shape are presented, and square-root law for the output spectrum broadening law has been […]
Combined Mueller and Jones matrix method for the evaluation of the complex modulation in a liquid-crystal-on-silicon display.
We apply the polar decomposition of the Mueller matrix describing a liquid-crystal-on-silicon display to identify the diattenuator, depolarizer, and retarder contributions as a function of the gray level. The retarder contribution is expressed in terms of […]
Simultaneous time- and wavelength-resolved fluorescence spectroscopy for near real-time tissue diagnosis.
A novel fiber-optic-based method for simultaneous time- and wavelength-resolved fluorescence spectroscopy for the rapid diagnosis of diseased tissue is demonstrated. By combining multiple bandpass and dichroic filters (405/40, 460/50, and 550/50) with different lengths of optical fiber (1, 10, and 19 m) […]
Scattering differentiates Alzheimer disease in vitro.
The molecular bases of Alzheimer disease and related neurodegenerative disorders are becoming better understood, but the means for definitive diagnosis and monitoring in vivo remain lacking. Near-infrared optical spectroscopy offers a potential solution. We acquired transmission and reflectance spectra of thin brain tissue slabs, from which we […]
Plasmon-assisted transparency in metal-dielectric microspheres: erratum.

Broadband light generation at ~1300 nm through spectrally recoiled solitons and dispersive waves.
We experimentally study the generation of broadband light at ~1300 nm from an 810 nm Ti:sapphire femtosecond pump laser. We use two photonic crystal fibers with a second infrared zero-dispersion wavelength (lambda(Z2)) and compare the efficiency of two schemes: in […]
