Quantities with right-skewed distributions are ubiquitous in complex social systems, including political conflict, economics and social networks, and these systems sometimes produce extremely largeâ€¦ (More)

An expression plasmid for mammalian cells (CLDN10B) has been modified to add nucleotides encoding hexahistidine and the FLAG peptide (H/F) to cDNAs. The new mammalian expression plasmid has beenâ€¦ (More)

We reply to the recent criticism by Garriga and Tanaka of our proposal that quantum gravitational loop corrections may lead to a secular screening of the effective cosmological constant. Theirâ€¦ (More)

We use dimensional regularization to compute the 1PI 1-point function of quantum gravity at one loop order in a locally de Sitter background. As with other computations, the result is a finiteâ€¦ (More)

We derive the propagator for a massive vector field on a de Sitter background of arbitrary dimension. This propagator is de Sitter invariant and possesses the proper flat spacetime and masslessâ€¦ (More)

We consider the back-reaction of quantum electrodynamics upon an electric field E(x+) = âˆ’Aâˆ’(x+) which is parallel to x and depends only on the lightcone coordinate x+ = (x 0 + x)/ âˆš 2. Novel featuresâ€¦ (More)

We derive a simple form for the propagator of a massless, minimally coupled scalar in a locally de Sitter geometry of arbitrary spacetime dimension. We then employ it to compute the fullyâ€¦ (More)

We describe our recent calculation of two-loop corrections to the expansion rate of an initially inflating universe on the manifold T 3 Ã—R. If correct, our result proves that quantum gravitationalâ€¦ (More)

The financial crisis of 2008, which started with an initially well-defined epicenter focused on mortgage backed securities (MBS), has been cascading into a global economic recession, whose increasingâ€¦ (More)

We consider the quantum gravitational back-reaction on an initially inflating, homogeneous and isotropic universe whose topology is T 3 Ã— R. Although there is no secular effect at one loop, anâ€¦ (More)
