Journal of Mathematics and Informatics, 2021 In this paper, we propose and analyze the perturbed mathematical model for modeling the portfolio of insurance companies with possibilities of recovery after ruin. Return on investment and refinancing are used as approaches for overcoming ruin. The model

International Journal of Mathematics for Industry, 2023 This paper studies the Gerber–Shiu function for the insurance surplus process with additional investment under the Bachelier model. The Gerber–Shiu function allows us to study the moments of the time of ruin, which is the first time that the surplus is ...

De-Co square. A New Life to a Building Adrift [PDF]
ARQ, 2022 If deconstruction means an understanding of structure to rethink it without destroying it, this project could be one of its best examples. Here, the abandonment of an old police station had transformed it into a lawless place -- that is, its opposite ...

On a Fractional Stochastic Risk Model with a Random Initial Surplus and a Multi-Layer Strategy
Mathematics, 2022 The paper deals with a fractional time-changed stochastic risk model, including stochastic premiums, dividends and also a stochastic initial surplus as a capital derived from a previous investment.

Male reproductive ageing: a radical road to ruin
Human Reproduction, 2023 In modern post-transition societies, we are reproducing later and living longer. While the impact of age on female reproductive function has been well studied, much less is known about the intersection of age and male reproduction.

A Note on a Modified Parisian Ruin Concept
Risks, 2023 Traditionally, Parisian ruin is said to occur when the insurer’s surplus process has stayed below level zero continuously for a certain grace period. Inspired by this concept, in this paper we propose a modification by assuming that once a grace period ...

Ruin probabilities as functions of the roots of a polynomial
Modern Stochastics: Theory and Applications, 2023 A new formula for the ultimate ruin probability in the Cramér–Lundberg risk process is provided when the claims are assumed to follow a finite mixture of m Erlang distributions. Using the theory of recurrence sequences, the method proposed here shifts the problem of finding the ruin probability to the study of an associated characteristic polynomial ...

Reversing the Ruin: Rehabilitation, Recovery, and Restoration After Stroke
Current Neurology and Neuroscience Reports, 2022 Stroke is a common cause of disability in aging adults. A given individual’s needs after stroke vary as a function of the stroke extent and location. The purpose of this review was to discuss recent clinical investigations addressing rehabilitation of an
