The role of inequalities in information theory is reviewed and the relationship of these inequalities to inequalities in other branches of mathematics is developed. I NEQUALITIES in information theory have been driven by a desire to solve communication theoretic problems. To solve such problems, especially to prove converses for channel capacity theorems,(More)
A system with many senders and receivers contains many new elements in the communication problem: interference, cooperation and feedback. These are the issues that are the domain of network information theory. The general problem is easy to state. Given many senders and receivers and a channel transition matrix which describes the effects of the(More)
BACKGROUND Diffusion tensor imaging (DTI) has been widely used in psychiatric research and has provided evidence of white matter abnormalities in first episode schizophrenia (FES). The goal of the present meta-analysis was to identify white matter deficits by DTI in FES. METHODS A systematic search was conducted to collect DTI studies with voxel-wised(More)
Nature has provided us with infections - acute and chronic - and these infections have both harmful and beneficial effects on the human system. Worldwide, a number of chronic infections are associated with a risk of cancer, but it is also known that cancer regresses when associated with acute infections such as bacterial, viral, fungal, protozoal, etc.(More)
