any 3d seismic survey can have an acquisition footprint. acquisition footprint is an expression of the surface geometry (most common on land data) that leaves an imprint on the stack of 3d seismic data. often we recognize it as amplitude and phase variations on time slices, which of course display the amplitudes within our data set at a specified two way time (cordsen, 2004). on the other hand,...

We examine the characteristics of effective leaders in a simple leader-follower voluntary contributions game. We focus on two factors: the individual’s cooperativeness and the individual’s beliefs about the cooperativeness of others. We find that groups perform best when led by those who are cooperatively inclined. Partly, this reflects a false consensus effect: cooperative leaders are more opt...

The enterococcal cytolysin is a virulence factor consisting of two post-translationally modified peptides that synergistically kill human immune cells. Both peptides are made by CylM, a member of the LanM lanthipeptide synthetases. CylM catalyzes seven dehydrations of Ser and Thr residues and three cyclization reactions during the biosynthesis of the cytolysin large subunit. We present here the...

Abstract In this study, we perform idealized climate model simulations to assess the relative impacts of an increase in local black carbon (BC) aerosols (located over Indian region) and remote BC outside on summer monsoon precipitation India. We decompose changes into fast adjustments triggered by introduction forcing agent slow response that is associated with global mean temperature change. f...
