We consider the problem of giving explicit spectral bounds for time inhomogeneous Markov chains on a finite state space. We give bounds that apply when there exists a probability π such that each of the different steps corresponds to a nice ergodic Markov kernel with stationary measure π. For instance, our results provide sharp bounds for models such as… (More)

Dietary supplementation with the n-3 polyunsaturated fatty acids (n-3 PUFA) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) to rats preconditions the liver against ischemia-reperfusion (IR) injury, with reduction of the enhanced nuclear factor-κB (NF-κB) functionality occurring in the early phase of IR injury, and recovery of IR-induced… (More)

We discussed problems posed by the quantitative study of time inhomoge-neous Markov chains. The two main notions for our purpose are merging and stability. Merging (also called weak ergodicity) occurs when the chain asymptotically forget where it started. It is a loss of memory property. Stability relates to the question of whether or not, despite temporal… (More)

Error control codes are widely used to increase the reliability of transmission of information over various forms of communications channels. Algebraic geometry (AG) codes were introduced by V. Goppa in the 1980's. The code-words in an AG code are obtained by evaluating functions at he points of an algebraic curve over a finite field; Goppa's construction… (More)
