The entropy evolution property of a single-mode light field interacting with V-type three-level atoms via intensity-dependent coupling has been studied, and the influence of detuning of light field and initial photon number on entropy evolution of field is discussed. It is found that if detuning...

The quadrature squeezing properties of an atom laser originating from atomic Bose–Einstein condensate interacting with light field are studied. We find that the squeezing properties of the atom laser are dependent on the initial light field interacting with the atomic Bose–Einstein...

This paper considers the optimal dividend problem with proportional reinsurance and capital injection for a large insurance portfolio. In particular, the reinsurance premium is assumed to be calculated via the variance principle instead of the expected value principle. Our objective is to...

This article presents a review of the issues associated with a manufacturer's pricing strategies in a two-echelon supply chain that comprises one manufacturer and two competing retailers, with warranty period-dependent demands. The manufacturer, as a Stackelberg leader, specifies wholesale...

Assume that an insurer has two dependent lines of business. The reserves of the two lines of business are modeled by a two-dimensional compound Poisson risk process or a common shock model. To protect from large losses and to reduce the ruin probability of the insurer, the insurer applies a...

In this paper, we consider the optimal dividend problem with transaction costs when the incomes of a company can be described by an upward jump model. Both fixed and proportional costs are considered in the problem. The value function is defined as the expected total discounted dividends up to...

As an important extension of the regular kappa statistic, the weighted kappa statistic has been widely used to assess the agreement between two procedures for independent matched-pair ordinal data. For clustered matched-pair ordinal data, based on the delta method and sampling techniques, a...

Based on the cost efficiency of individual banks, this paper constructs an indicator to clarify Chinese regional banking system’s credit allocation efficiency in accordance with the panel data of the provinces and central-government-administered cities of China. When applying this...

Panel attrition is frequently encountered in panel sample surveys. When it is related to the observed study variable, the classical approach of nonresponse adjustment using a covariate-dependent dropout mechanism can be biased. We consider an efficient method of estimation with monotone panel...

This paper introduces a new characterization of multivariate normality of a random vector based on univariate normality of linear combinations of its components.
