When Dark Matter interacts with Cosmic Rays or Interstellar Matter: A Morphological Study

Excess emission over expected diffuse astrophysical backgrounds in the direction of the Galactic center region has been claimed at various wavelengths, from radio to gamma rays. Among particle models advocated to explain such observations, several invoke interactions between dark matter particles and ordinary matter, such as cosmic rays, interstellar gas or free electrons. Depending on the specific interstellar matter particles' species and energy, such models predict distinct morphological features. In this study we make detailed predictions for the morphology of models where the relevant electromagnetic emission is proportional to the product of the dark matter density profile and the density of interstellar matter or cosmic rays. We compare the predicted latitudinal and longitudinal distributions with observations, and provide the associated set of relevant spatial templates.Comment: 10 pages, 4 figures, submitted; Supplementary code and emission skymaps available at http://planck.ucsc.edu/dmcr-morpholog

Best Practices in Assisted Living: Considering Potential Reforms for California

Based on a review of assisted living laws of California and 11 other states, California's assisted living policy is significantly out of date. An assisted living resident today is likely to have significant care needs, but California's law in general has low standards for quality of care. Unlike many other states, California has not adjusted adequately to the sharp increase in residents' care needs over the past 10 to 15 years. California's assisted living law was enacted in 1985, and has been amended only intermittently since then. It requires significant revision in order to keep pace with the new realities of assisted living

Gravitino Dark Matter and Flavor Symmetries

In supersymmetric theories without R-parity, the gravitino can play the role of a decaying Dark Matter candidate without the problem of late NLSP decays affecting Big Bang Nucleosynthesis. In this work, we elaborate on recently discussed limits on R-parity violating couplings from decays to antideuterons and discuss the implications for two classes of flavor symmetries: horizontal symmetries, and Minimal Flavor Violation. In most of the parameter space the antideuteron constraints on R-parity violating couplings are stronger than low-energy baryon-number-violating processes. Even in the absence of flavor symmetries, we find strong new limits on couplings involving third-generation fields, and discuss the implications for LHC phenomenology. For TeV scale superpartners, we find that the allowed MFV parameter space is a corner with gravitino masses smaller than O(10) GeV and small $\tan\beta$.Comment: 19 pages, matches JHEP published version.

High throughput microbalance and methods of using same

A method and apparatus for measurement of mass of small sample sizes. The method and apparatus is particularly adapted for providing microbalance measurement of solid materials as part of a combinatorial research program. The method and apparatus contemplate monitoring the response of a resonator holding a sample and correlating the response with mass change in the samples
