In this paper we prove a new matrix Li-Yau-Hamilton (LYH) estimate for Kähler-Ricci flow on manifolds with nonnegative bi-sectional curvature. The form of this new LYH estimate is obtained by the interpolation consideration originated in [Ch] by Chow. This new inequality is shown to be connected with Perel-man's entropy formula through a family of… (More)
Genome sequences of Methylobacter luteus, Methylobacter whittenburyi, Methylosarcina fibrata, Methylomicrobium agile, and Methylovulum miyakonense were generated. The strains represent aerobic methanotrophs typically isolated from various terrestrial ecosystems.
OBJECTIVE This article sought to define whether an alternative safety-engineered device (SED) could help prevent needlestick injury (NSI) in healthcare workers (HCWs) who place central venous catheters (CVCs). DESIGN The study involved three phases: (1) A retrospective analysis of deidentified occupational health records from our tertiary care urban US… (More)

Bentley et al.'s scheme generates distributions characteristic of situations of high and low social influence on decisions and of high and low salience ("transparency") of rewards. Another element of decisions that may influence the placement of a decision process in their map is the way in which individual decisions interact to determine the payoffs. This… (More)
INTRODUCTION The smallpox vaccination emergency preparedness program has been unsuccessful in enrolling sufficient numbers of healthcare workers. OBJECTIVE The objective of this study was to use game theory to analyze a pre-event vaccination versus post-event vaccination program using the example of a terrorist considering an attack with smallpox or a… (More)
In this paper we consider the class A of those solutions u(x, t) to the conjugate heat equation d dt u = −∆u + Ru on compact Kähler manifolds M with c 1 > 0 (where g(t) changes by the unnormalized Kähler Ricci flow, blowing up at T < ∞), which satisfy Perelman's differential Harnack inequality on [0, T). We show A is nonempty. If |Ric(g(t))| ≤ C T −t ,… (More)
