Electric Field Effects on Emission Line Shapes when Electron Transfer Competes with Emission:an Example from Photosynthetic Reaction Centers
RHODOBACTER-SPHAEROIDES R-26 PRIMARY CHARGE SEPARATION RHODOPSEUDOMONAS-VIRIDIS BACTERIAL PHOTOSYNTHESIS FEMTOSECOND SPECTROSCOPY PROTEIN SUBUNITS 3A RESOLUTION PRIMARY DONOR SPECTRA
2016/5/23
Electron-transfer reactions are expected to be particularly sensitive to externally applied electric fields because of the presence of charge-separated, dipolar states, and the effects of the field on...
Spin-up of rubble-pile asteroids:Disruption,satellite formation,and equilibrium shapes
Asteroid, Dynamics Rotational dynamics Satellites,Dynamics
2015/12/25
We present results from numerical experiments testing the behavior of cohesionless gravitational aggregates experiencing a gradual increase of angular momentum. The test bodies used in these numerical...
Asteroids:equilibrium shapes of rotating gravitational aggregates
Asteroids shapes–Numerical simulations–Solar System evolution
2015/12/25
Many evidences lead us to think that a significant portion of asteroids are aggregates of boulders kept together by gravity, with little or no contribution from cohesive forces. The standard hydrodyna...
RUBBLE-PILE RESHAPING REPRODUCES OVERALL ASTEROID SHAPES

2015/12/25
There have been attempts in the past to fit the observed bulk shapes (axial ratios) of asteroids to theoretical equilibrium figures for fluids, but these attempts have not been successful in many case...
Asteroid rotation and shapes from numerical simulations of gravitational re-accumulation
Asteroids Asteroid formation Asteroid evolution Collisions
2015/12/25
We present simulations of the gravitational collapse of a mono-disperse set of spherical particles for studying shape and spin properties of re-accumulated members of asteroid families. Previous numer...

2015/12/25
We present numerical experiments investigating the shape and spin limits of self-gravitating “perfect” rubble piles that consist of identical, smooth, rigid, spherical particles with configurable norm...
COMPARISON OF PARSING TECHNIQUES FOR THE SYNTACTIC PATTERN RECOGNITION OF SIMPLE SHAPES

Contamination from instrumental effects interacting with bright astrophysical sources is the primary impediment to measuring Epoch of Reionization and BAO 21 cm power spectra-an effect called mode-mix...
Maximal supports and Schur-positivity among connected skew shapes
Symmetric function Schur-positive support skew shape ribbon
2011/9/19
Abstract: The Schur-positivity order on skew shapes is defined by B \leq A if the difference s_A - s_B is Schur-positive. It is an open problem to determine those connected skew shapes that are maxima...
We develop a general theory for estimating the probability that a galaxy cluster of a given shape exists. The theory is based on the observed result that the distribution of galaxies is very close to ...
