Five microsatellite markers were selected for studying the DNA polymorphism of fat-tailed sheep, aiming to understand the genetic diversity of this species. The genetic diversity of five microsatellite markers (BL1038, BM757, BM4621, OarFCB304 and OarFCB48) in fat-tailed sheep population was detected through the native polyacrylamide gel electrophoresis. The results indicated that fat-tailed sh...

In this paper we consider a generalization of the so-called M=G=1 model where M types of long-tailed sessions enter a buffer . The instantaneous rates of the sessions are functions of the occupancy of an M=G=1 system with long-tailed G distributions. In particular we assume that a session of type i transmits ri cells per unit time and lasts for a random time with long tailed distribution given ...

Understanding the influence of habitat alteration on population structure and persistence is critical for effective conservation strategies. Timber harvest and wildfire are two of the most prevalent disturbances across temperate forests, yet the long-term effects of these two forces on population connectivity have rarely been studied. We studied populations of the Rocky Mountain tailed frog (As...

Stochastic Neighbor Embedding (SNE) has shown to be quite promising for data visualization. Currently, the most popular implementation, t-SNE, is restricted to a particular Student t-distribution as its embedding distribution. Moreover, it uses a gradient descent algorithm that may require users to tune parameters such as the learning step size, momentum, etc., in finding its optimum. In this p...

The natural occurrence of chronic wasting disease (CWD) in a 1993 cohort of captive white-tailed deer (Odocoileus virginianus) afforded the opportunity to describe epidemic dynamics in this species and to compare dynamics with those seen in contemporary cohorts of captive mule deer (O. hemionus) also infected with CWD. The overall incidence of clinical CWD in white-tailed deer was 82% (nine of ...

We study the time it takes until a a uid queue with a nite, but large, holding capacity reaches the overrow point. The queue is fed by an on/oo process, with a heavy tailed on distribution, which is known to have long memory. It turns out that the expected time until overrow, as a function of capacity L, increases only polynomially fast, and so overrows happen much more often than in the \class...

We discuss non-Gaussian random matrices whose elements are random variables with heavy-tailed probability distributions. In probability theory heavy tails of the distributions describe rare but violent events which usually have dominant influence on the statistics. They also completely change universal properties of eigenvalues and eigenvectors of random matrices. We concentrate here on the uni...

Abstract. The upper extremes of a Markov chain with regulary varying stationary marginal distribution are known to exhibit under general conditions a multiplicative random walk structure called the tail chain. More generally, if the Markov chain is allowed to switch from positive to negative extremes or vice versa, the distribution of the tail chain increment may depend on the sign of the tail ...

Child.A correspondent of Science (June 6th) de~ scribes a tailed child which was recently born in Louisville, Ivy. The child was visited by a party of four, which included a prominent physician. The writer says :? " We found a female negro child, eight weeks old, normally formed in all respects, except that slightly to the left of the median line, and about an inch above the lower end of the sp...
