Background: To provide, maintain and promote the health of children as a vulnerable group in the health service has a special place. So, the first step in reducing mortality and improve their health, identify causes of morbidity and mortality. Materials and Methods: In this retrospective study, the main causes of neonate death in the case of neonatal who died in Aboozar hospital in 1390 ...
It has been known for a long time that for birth-and-death processes started in zero the first passage time of a given level is distributed as a sum of independent exponentially distributed random variables, the parameters of which are the negatives of the eigenvalues of the stopped process. Recently, Diaconis and Miclo have given a probabilistic proof of this fact by constructing a coupling be...
این قطعه یک سوییت سمفونیک ، برای ارکستر سمفونیک درسه موومان به شرح زیر می باشد. موومان اول : تولد (the birth) موومان دوم : زندگی (the life) مووما ن سوم : مرگ (the death) این موضوع ( تولد ، زندگی ، مرگ ) همیشه برای من جذابیت داشته است و با توجه به اینکه این قانون در زندگی ما جاری است ، علاقه مند بودم ذهنیا ت خود را دررابطه با این موضوع بیان کنم. تا به حا ل حتما" متوجه شده ایم که هر اثر،...
Network models extend evolutionary game theory to settings with spatial or social structure and have provided key insights on the mechanisms underlying the evolution of cooperation. However, network models have also proven sensitive to seemingly small details of the model architecture. Here we investigate two popular biologically motivated models of evolution in finite populations: Death-Birth ...
This article defines and describes the level-dependent quasi-birth-and-death (LDQBD) process, a generalization of the homogeneous (or level-independent) quasi-birth-and-death (QBD) process. Like its level-independent counterpart, the LDQBD process is a bivariate Markov process whose transition probability matrix (or infinitesimal generator matrix) exhibits a block tri-diagonal structure. Howeve...
