background: type-i diabetes is an autoimmune inflammatory disease in which pancreatic ß-cells are selectively destroyed by infiltrating cells. tnf-related apoptosis-inducing ligand (trail) is a type-ii membrane protein of the tnf superfamily which is expressed in different tissues, including pancreas and lymphocytes. in humans, trail interacts with four membrane receptors. trail-r1 and trail-r2...

The classical economic production quantity (EPQ) model is a well-known and commonly used inventory control technique. Common assumptions in this model are that all units produced are of perfect quality and shortage is not allowed, since in practice shortage, non-conforming product or scrap items are possible, these assumptions will underestimate the actual required quantity. The objective of th...

Transforming growth factor beta (TGF-beta), a multifunctional cytokine that regulates a variety of biological functions, signals through a heteromeric receptor complex of the type I and type II TGF-beta receptors. The type II receptor, a transmembrane serine-threonine kinase, was cloned based on its ability to directly bind TGF-beta. Recently, a number of candidate type I TGF-beta receptors hav...

In this paper, we propose a cross-layer design which combines adaptive modulation and coding (AMC) at the physical layer with a hybrid automatic repeat request (HARQ) protocol at the data link layer to minimize the packet error rate (PER) and maximize the spectral efficiency. By using Markov model to predict the channel condition of next frame according to the second order statistics characteri...

A common type of reliability data is the right censored time-to-failure data. In this article, we developed a control chart to monitor the time-to-failure data in the presence of right censoring using weighted rank tests. On the basis of the asymptotic properties of the rank statistics, we derived the generic formulae for the operating characteristic functions of the control chart to show the r...

This paper considers an Extended Generalized Half Logistic distribution. We derive some properties of this distribution and then we discuss estimation of the distribution parameters by the methods of moments, maximum likelihood and the new method of minimum spacing distance estimator based on complete data. Also, maximum likelihood equations for estimating the parameters based on Type-I and Typ...
