Dark Matter Detection With Electron Neutrinos in Liquid Scintillation Detectors
We consider the prospects for liquid scintillation experiments (with a focus
on KamLAND) to detect the flux of electron neutrinos arising from dark matter
annihilation in the core of the sun. We show that, with data already taken,
KamLAND can provide the greatest sensitivity to the dark matter-proton
spin-dependent scattering cross-section for dark matter lighter than 20 GeV. It
is also possible to probe the dark matter-nucleon spin-independent scattering
cross-section for isospin-violating dark matter lighter than 10 GeV. KamLAND
can thus potentially confirm the dark matter interpretation of the DAMA and
CoGeNT signals, utilizing data already taken.Comment: 5 pages, 4 figures, PDFLaTeX; v2: references added, figures updated,

Astrophysical tau neutrinos and their detection by large neutrino telescopes
We present results of the detailed Monte Carlo calculation of the rates of
double-bang events in 1 km underwater neutrino telescope with taking into
account the effects of -neutrino propagation through the Earth. As an
input, the moderately optimistic theoretical predictions for diffuse neutrino
spectra of AGN jets are used.Comment: Talk given at the NANP'03 conference, June 2003. 4 pages, one eps

PC tools for project management: Programs and the state-of-the-practice
The use of microcomputer tools for NASA project management; which features are the most useful; the impact of these tools on job performance and individual style; and the prospects for new features in project management tools and related tools are addressed. High, mid, and low end PM tools are examined. The pro's and con's of the tools are assessed relative to various tasks. The strengths and weaknesses of the tools are presented through cases and demonstrations
