Fragile histidine triad (FHIT) serves a critical function as a tumor suppressor that inhibits p53 degradation by mouse double minute 2 (MDM2). The functional domains of FHIT involved in tumor inhibition was interpreted. In-silico screening data were employed to construct truncated forms of FHIT to assess their cytotoxic effects on the HT1080 cell line. Full FHIT expression was confirmed by west...

Given an algebraic ordinary differential equation (AODE), we propose a computational method to determine when truncated power series can be extended formal solution. If certain regularity condition on the given AODE or initial values is fulfilled, compute all of solutions. Moreover, existence confirmed, present structure set

In this paper, the stochastic fixed-point equation X d = inf i≥1: Ti>0 Xi/Ti is studied, where d = means equality in law, (Xn)n≥1 and T = (Ti)i≥1 denote independent sequences of non-negative random variables, and X1,X2, ... are independent copies of the random variable X. Under suitable conditions on the given weight sequence T , most notably that 1 < EN < ∞ for N = ∑ i≥1 1{Ti>0} and that T has...

In this paper we propose a mixture of two different distributions such as Exponential-Gamma, Exponential-Weibull and Gamma-Weibull to model heterogeneous survival data. Various properties of the proposed mixture of two different distributions are discussed. Maximum likelihood estimations of the parameters are obtained by using the EM algorithm. Illustrative example based on real data are also g...

The statistics of texture operators on natural images are empirically determined to conform to a Weibull process. We explain these findings from the physical principles of fragmentation processes. The Weibull parameters are known to indicate the fractal dimension of the underlying system. Hence, we show the Weibull process to have a physical foundation for describing natural image statistics. K...

Weibull distribution was used to fit tree diameter data collected from 86 sample plots located in Chinese pine stand in Beijing. To estimate the Weibull distribution parameters, three methods [namely maximum likelihood estimation method (MLE), method of moment (MOM) and least-squares regression method (LSM)] were compared and evaluated on the basis of the mean square error (MSE) and sample size...

Ascertaining the importance of the recently proposed spatial modulation, we study its performance in Weibull multipath fading channels. Closed form integral expressions for calculating the symbol error rate of spatial modulation (SM) in independent, not necessarily identical Weibull fading channels are derived. Simulation and the analytical results, considering different transmission scenarios,...

background : so far, several studies were conducted to estimate the prevalence of cigarette smoking in iran, but none of them used a statistical model to deal with unobserved smokers. the present study planned to estimate the accurate prevalence of cigarette smoking using mixture of truncated poisson distribution. methods : a cross-sectional study was conducted in hamadan, west of iran in 2009,...

The distribution of earthquake interevent times is a subject that has attracted much attention in the statistical physics literature [1-3]. A recent paper proposes that the distribution of earthquake interevent times follows from the the interplay of the crustal strength distribution and the loading function (stress versus time) of the Earth’s crust locally [4]. It was also shown that the Weibu...
