background: the aim of this study was to propose a new stochastic model to study the time course of ethanol elimination in human bodies. methods: the times and amount of alcohol ingested are assumed to be random in controllable intervals. constant elimination rate follows zero order kinetics and is replaced by first order kinetics when the effects of alcohol increase due to alcohol ingestion. s...

To further improve the security of digital image steganography, based on graph transformation diversity, proposed a zero-steganographic model. After divided into many blocks, the secret information is deduced by graphic transform algorithm, and a cover image steganographic model for not carrying secret information is constructed. First step is selecting a batch of cover images through a particu...

A multicluster model of traffic flow is studied, in which the motion of cars is described by a stochastic master equation. Assuming that the escape rate from a cluster depends only on the cluster size, the dynamics of the model is directly mapped to the mathematically well-studied zero-range process. Knowledge of the asymptotic behavior of the transition rates for large clusters allows us to ap...

We study the bridge between the phenomenological mass matrix model and SO(10) GUT. Namely, we consider the four zero texture model in the framework of the renormalizable SO(10) GUT model. This unification gives more stringent constraints than the case where only either model is considered. However, we can obtain good fitting by expanding the minimal SO(10) GUT to include 120 in addition to 10 a...

Excess zeros and overdispersion are commonly encountered phenomena that limit the use of traditional Poisson regression models for modeling count data. The focus of this paper is on modeling count data in the case that a population has excess zero counts and also consists of several sub-populations in the non-zero counts. The proposed zero-inflated Poisson regression mixture model accounts for ...

We propose an extension of the standard Dolev-Yao model of cryptographic protocols to facilitate symbolic reasoning about zeroknowledge proofs. This is accomplished by communicating typed terms, and providing a proof amounts to certifying that a term is of a particular type. We present a proof system for term derivability, which is employed to yield a decision procedure for checking whether a g...

For a zero-mean Gaussian process, the covariances of zero crossings can be expressed as the sum of quadrivariate normal orthant probabilities. In this paper, we demonstrate the evaluation of zero crossing covariances using one-dimensional integrals. Furthermore, we provide asymptotics of zero crossing covariances for large time lags and derive bounds and approximations. Based on these results, ...

Multi-Speaker activity (MSA) detection helps in detecting the presence of whether the speech signals has a single speaker or multiple speaker speeches in the speech signal. It is easy to calculate the slope at ZCs (zero crossings) of the speech signal and makes a comparison with a suitable threshold (Th). Multi-speaker is declared as and when the zero crossing value exceeds the threshold. The i...
