The Gerber-Shiu function provides a way of measuring the risk of an insurance company. It is given by the expected value of a function that depends on the ruin time, the deficit at ruin, and the surplus prior to ruin. Its computation boils down to the evaluation of the overshoot/undershoot distributions of the surplus process at ruin. In this paper, we approximate it in a closed form by fitting...

We introduce an algebraic operator framework to study discounted penalty functions in renewal risk models. For inter-arrival and claim size distributions with rational Laplace transform, the usual integral equation is transformed into a boundary value problem, which is solved by symbolic techniques. The factorization of the differential operator can be lifted to the level of boundary value prob...

Abstract Date Presented 04/01/2022 We present results of a latent variable path analysis indicating that postconcussive symptoms may heighten risk for suicidal thoughts among Veterans by limiting successful participation. discuss implications with respect to OT’s role in suicide prevention efforts.

introduction : to evaluate the efficacy of niti mechanical rotary instrumentation and hedstrom file for gutta-percha/sealer removal computed tomography (ct) was utilized in vitro . materials and methods: thirty extracted human single rooted teeth, each with a single canal were selected. the samples were decoronated with a double faced diamond disk to have 17-mm root; teeth roots were instrument...

introduction: the purpose of this study was to evaluate and compare canal preparation pattern of k3 and protaper rotary files in curved resin blocks. materials and methods: twenty-four resin blocks were used in this experimental study and randomly divided into two groups. their initial images were scanned. after preparation, their images were scanned again in the same position. pre and post pre...
