Ruin-based risk measures in discrete-time risk models
Insurance, Mathematics & Economics, 2020 For an insurance company, effective risk management requires an appropriate measurement of the risk associated with an insurance portfolio. The objective of the present paper is to study properties of ruin-based risk measures defined within discrete-time

Inequalities for the ruin probability in a controlled discrete-time risk process [PDF]
, 2009 Ruin probabilities in a controlled discrete-time risk process with a Markov chain interest are studied. To reduce the risk there is a possibility to reinsure a part or the whole reserve. Recursive and integral equations for ruin probabilities are given.

Reinvigorating Life of Southern Italy Fortified Architecture in Ruin: From Knowledge to Conservation [PDF]
Athens Journal of Architecture, 2020 Southern Italy, the ancient Kingdom of Naples and Sicily, shows a rich heritage of fortified architecture, with towers, castles, boundary walls and any other defensive works, witnesses of historical seasons of sieges and enemy attacks.

Uniform asymptotics for finite-time ruin probability of a bidimensional risk model
Journal of Mathematical Analysis and Applications, 2019 Consider a continuous-time bidimensional risk model with constant force of interest in which the claim sizes from the same business are heavy-tailed and upper tail asymptotically independent.

Martingales and the distribution of the time to ruin
Stochastic Processes and their Applications, 2003 The author considers the classical risk model, where claims arrive according to a renewal process, with waiting times that are of phase-type, while the claims themselves follow a distribution with a Laplace transform that is a rational function. Using martingales, the optional sampling theorem and the theory of piecewise Markov process, he determines ...

Ruin probability and time of ruin with a proportional reinsurance threshold strategy [PDF]
TOP, 2010 In this paper, we present a threshold proportional reinsurance strategy and we analyze the effect on some solvency measures: ruin probability and time of ruin. This dynamic reinsurance strategy assumes a retention level that is not constant and depends on the level of the surplus.

PANoptosis in the pathogenesis of myelodysplastic syndromes
Molecular Oncology, EarlyView.PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

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.

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer
Molecular Oncology, EarlyView.Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.
