A Local Energy Estimate On Kerr Black Hole Backgrounds, Daniel Tataru, Mihai H. Tohaneanu Jan 2011

A Local Energy Estimate On Kerr Black Hole Backgrounds, Daniel Tataru, Mihai H. Tohaneanu

Mihai H. Tohaneanu

We study dispersive properties for the wave equation in the Kerr space–time with small angular momentum. The main result of this paper is to establish uniform energy bounds and local energy decay for such backgrounds. This follows similar results for the Schwarzschild space–time proved earlier in [3], [8], and [16] and extended in earlier work [29] of the authors and collaborators.


Enantiocontrolled Solid-State Photodimerizations Via A Chiral Sulfonamidecinnamic Acid, Kraig A. Wheeler, Joshua D. Wiseman, Rebecca C. Grive Jan 2011

Enantiocontrolled Solid-State Photodimerizations Via A Chiral Sulfonamidecinnamic Acid, Kraig A. Wheeler, Joshua D. Wiseman, Rebecca C. Grive

Kraig A. Wheeler

The supramolecular patterns of three polymorphs of a chiral sulfonamidecinnamic acid reveal components effectively organized into predetermined hydrogen-bonded dimers with favorable <3.8A ° olefin spacing for enantioselective single-crystal-to-single-crystal [2 + 2] photodimerization reactions.

A Primer Of Swarm Equilibria, Andrew J. Bernoff, Chad M. Topaz Jan 2011

A Primer Of Swarm Equilibria, Andrew J. Bernoff, Chad M. Topaz

Chad M. Topaz

We study equilibrium configurations of swarming biological organisms subject to exogenous and pairwise endogenous forces. Beginning with a discrete dynamical model, we derive a variational description of the corresponding continuum population density. Equilibrium solutions are extrema of an energy functional, and satisfy a Fredholm integral equation. We find conditions for the extrema to be local minimizers, global minimizers, and minimizers with respect to infinitesimal Lagrangian displacements of mass. In one spatial dimension, for a variety of exogenous forces, endogenous forces, and domain configurations, we find exact analytical expressions for the equilibria. These agree closely with numerical simulations of the underlying …

Niche Of Harmful Alga Aureococcus Anophagefferens Revealed Through Ecogenomics, Christopher Gobler, Dianna Berry, Sonya Dyhrman, Steven Wilhelm Jan 2011

Niche Of Harmful Alga Aureococcus Anophagefferens Revealed Through Ecogenomics, Christopher Gobler, Dianna Berry, Sonya Dyhrman, Steven Wilhelm

Steven Wilhelm

Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide. Despite considerable efforts, a comprehensive understanding of the factors that promote these blooms has been lacking, because the biochemical pathways that facilitate their dominance relative to other phytoplankton within specific environments have not been identified. Here, biogeochemical measurements showed that the harmful alga Aureococcus anophagefferens outcompeted co-occurring phytoplankton in estuaries with elevated levels of dissolved organic matter and turbidity and low levels of dissolved inorganic nitrogen. We subsequently sequenced the genome of A. anophagefferens and compared its gene complement with those of six competing phytoplankton species identified through metaproteomics. …
