In this article, I develop a methodology for inferring the transmission rate and reproductive value of an epidemic on the basis of genotype data from a sample of infected hosts. The epidemic is modeled by a birth-death process describing the transmission dynamics in combination with an infinite-allele model describing the evolution of alleles. I provide a recursive formulation for the probabili...

It has been hypothesized that number of road accidents and road casualties are increased in line with the raise in the variables of registered vehicles, population and road length. However, the effects of these variables toward road accidents are still inconclusive. Therefore, this paper develops models based on the variables which can be used to determine road accidents in Malaysia. In order t...

children’s behavior and their personality formation can be influenced by the mode of their interactions with their parents. according to this assumption, it can be said that the method of upbringing in the family plays a determinative role in the formation of religious orientation in children. the principal supposition is that the three authoritative, permissive and authoritarian styles noted b...

Today, organizational entrepreneurship is considered as an effective factor in growth, creativity and dynamicity of organizations in order for their promotion and survival. Therefore, the present study aims to identify and explain the dimensions of an entrepreneur-training organization and its impact on the organization’s policies. The research method, due to sequence of qualitative and quantit...

In this paper, we will give a certain formula for the Riemann zeta function that expresses the Riemann zeta function by an infinte series consisting of KBessel functions. Such an infinite series expression can be regarded as an analogue of the Chowla-Selberg formula. Roughly speaking, the Chowla-Selberg formula is the formula that expresses the Epstein zeta-function by an infinite series consis...

The present study was conducted to investigate the factors influencing ethnic solidarity among young people (18-30 years) in the Azeri regions of Khalkhal. Theoretical framework was presented using the theories Emile Durkheim, Ted Robert Gurr, George Homans, Anthony Giddens and others. The research method was survey, face validity was used and reliability was obtained by Cronbach's alpha coeffi...

We derive a Feynman-Kac formula for functionals of a stochastic hybrid system evolving according to a piecewise deterministic Markov process. We first derive a stochastic Liouville equation for the moment generator of the stochastic functional, given a particular realization of the underlying discrete Markov process; the latter generates transitions between different dynamical equations for the...

this research through comparison study of application of ict on marketing of agricultural crops in khozestan province, evaluate the role of such factors. the study is of applied type and the method being used is descriptive- correlational. statistical population of this research is all agricultural experts of khuzestan province and using cochran’s formula , a sample size of 144 members was sele...
