In the final months of the project, we cracked the problem of determining the rate region of the vector Gaussian "one-helper" source coding problem. This problem was one of the most fundamental open problems in information theory, and had withstood repeated attacks by several groups around the world, starting with Liu and Viswanath (2007). The problem is similar to that of determining the capac...

We model the dynamics of social structure by a simple interacting particle system. The social standing of an individual agent is represented by an integer-valued fitness that changes via two offsetting processes. When two agents interact one advances: the fitter with probability p and the less fit with probability 1− p. The fitness of an agent may also decline with rate r. From a scaling analys...

OBJECTIVES To evaluate the response to induction therapy with intravenous (i.v.) cyclophosphamide (CYC) in Korean patients with class IV-G (diffuse global proliferative glomerulonephritis) and class IV-S (diffuse segmental proliferative glomerulonephritis) lupus nephritis (LN) according to the classification system of the International Society of Nephrology/Renal Pathology Society (ISN/RPS). ...
