Highly Sensitive, Low‐Cost Deep‐UV Resonant Raman Microspectroscopy Systems

open access: yesChemistry–Methods, EarlyView.
Low‐cost deep UV resonant Raman microscope for chemical sensing and imaging has been developed and its performance has been experimentally validated for several potential applications. Multimodal imaging capabilities of a new instrument have been demonstrated as well.

Field population II blue stragglers

open access: yesThe Astrophysical Journal, 1981
Photometry and high-resolution spectra are presented and discussed of metal-poor stars hotter than the turn-off of globular clusters. Very few nonvariable candidates for blue stragglers can be identified One, HD 100363, is probably an old-disk short-period variable.

Predicting the Uniform Electron Gas Stopping Power at Moderate and Strong Coupling

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT This paper presents a detailed study of the stopping power of a homogeneous electron gas in moderate and strong coupling regimes using the self‐consistent version of the method of moments as the key theoretical approach capable of expressing the dynamic characteristics of the system in terms of the static ones, which are the moments.

Star Formation History and Chemical Evolution of the Sextans Dwarf Spheroidal Galaxy

open access: yes, 2009
We present the star formation history and chemical evolution of the Sextans dSph dwarf galaxy as a function of galactocentric distance. We derive these from the $VI$ photometry of stars in the $42' \times 28'$ field using the SMART model developed by Yuk

Most mammals do not wander: few species escape continental endemism

open access: yesEcography, EarlyView.
Terrestrial mammals are found nearly everywhere on Earth. Yet, most taxa are endemic to a single continent; geological, evolutionary, ecological, or physiological filters constrain geographic distributions. Here, we synthesize data on geography, taxonomy, lineage age, dispersal, body size, and diet for > 4000 terrestrial mammals prior to detectable ...
