Nonequilibrium dynamics in noncommutative spacetime
AbstractWe study the effects of spacetime noncommutativity on the nonequilibrium dynamics of particles in a thermal bath. We show that the noncommutative thermal bath does not suffer from any further...
View ArticleOn neutrino flavor states
AbstractWe review the issues associated with the construction of neutrino flavor states. We then provide a consistent proof that the flavor states are approximately well-defined only if neutrinos are...
View ArticleNew light species and the CMB
AbstractWe consider the effects of new light species on the Cosmic Microwave Background. In the massless limit, these effects can be parameterized in terms of a single number, the relativistic degrees...
View ArticleDoes the BICEP2 observation of cosmological tensor modes imply an era of...
AbstractBICEP2 observations, interpreted most simply, suggest an era of inflation with energy densities of order (1016 GeV)4, not far below the Planck density. However, models of TeV gravity with large...
View ArticleInstability of quantum de Sitter spacetime
AbstractQuantized fields (e.g., the graviton itself) in de Sitter (dS) spacetime lead to particle production: specifically, we consider a thermal spectrum resulting from the dS (horizon) temperature....
View ArticleDetermination of nonlinear genetic architecture using compressed sensing
AbstractBackgroundOne of the fundamental problems of modern genomics is to extract the genetic architecture of a complex trait from a data set of individual genotypes and trait values. Establishing...
View ArticleMacroscopic Einstein equations for a cosmological model with a λ term
AbstractBy averaging the Einstein equations over transverse gravitational perturbations we obtain a closed set of two ordinary differential equations describing the macroscopic cosmological evolution...
View ArticleGIA-Net: Global Information Aware Network for Low-Light Imaging
AbstractIt is extremely challenging to acquire perceptually plausible images under low-light conditions due to low SNR. Most recently, U-Nets have shown promising results for low-light imaging....
