Global biodiversity is in rapid decline, yet the key threats to wildlife in many regions remain uncertain. Bats are one of the most diverse mammalian groups, playing vital roles in the ecosystems. There are at least 140 bat species in China, with 30

In this paper, we consider an insurance risk model with two-sided jumps, where downward and upward jumps typically represent claim amounts and random gains, respectively. We use the Laguerre series to expand the Gerber–Shiu function and estimate it

Abstract The expansion of anthropogenic noise poses an emerging threat to the survival and reproductive success of various organisms. Previous investigations have focused on the detrimental effects of anthropogenic noise on the foraging behavior in s

This paper considers a d-dimensional stochastic optimization problem in neuroscience. Suppose the arm’s movement trajectory is modeled by high-order linear stochastic differential dynamic system in d-dimensional space, the optimal trajectory, veloc

This article studies the optimal mean-variance reinsurance-investment selection for insurers with mispricing. Assuming that insurers wish to purchase proportional/excess-of-loss reinsurance and exc...

In this paper, we adopt a Poisson approach to find Laplace transforms of joint occupation times over n disjoint intervals for pre-exit diffusion processes. Then we generalize previous result for the 2-dimensional case and the 3-dimensional case.

In this paper, we analyze a robust optimal investment-reinsurance problem involving a defaultable security for an ambiguity-averse insurer(AAI), who worries about uncertainty in model parameters. T...
