Asymptotic Behavior of the Two Level Measure Branching Process

Asymptotic Genealogy of a Critical Branching Process

Consider a continuous-time binary branching process conditioned to have population size n at some time t, and with a chance p for recording each extinct individual in the process. Within the family tree of this process, we consider the smallest subtree containing the genealogy of the extant individuals together with the genealogy of the recorded extinct individuals. We introduce a novel represe...

Asymptotic Behavior of Branching Populations before Extinction

where Xn denotes the number of offspring in the nth generation for a population starting from K offsprings, X0 = K, and throughout the paper the initial size of population K is assumed to be a large value. Such a type of branching process can be a model of real population of animals, insects etc., and the main results of our study can have applications to analysis of real populations arising in...

Asymptotic Distribution of Divergence Measure with Applications

The Entrance Space of a Measure - Valued Markov Branching Process

We explicitly identify the possible probability entrance laws for a class of measure-valued processes that are constructed by taking a particular measure-valued Markov branching process and conditioning it to stay away from the zero measure trap. The set of extreme points of the entrance space is larger than the state space of the conditioned process, and contains elements which correspond to "...

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
