Ruin probabilities in a finite-horizon risk model with investment and reinsurance [PDF]
A finite horizon insurance model is studied where the risk/reserve process can be controlled by reinsurance and investment in the financial market. Obtaining explicit optimal solutions for the minimizing ruin probability problem is a difficult task ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Beyond Repair? Ruins and Rubble in Ian McEwan’s Atonement
Études Britanniques Contemporaines, 2012 In his representation of England in the 1930s and of the Second World War, McEwan’s Atonement stages shattered worlds, both public and private, from derelict marriages and ruined relationships to the rubble of the Dunkirk retreat and the soldiers ...

Intersections of two ruin probability functions
Mathematical Communications, 2011 In this paper we study intersections of ruin probability functions for two risk models.The number of intersection points is determined for some of the most widely used models. It is also shown that there exist risk processes with ruin probability functions intersecting in an arbitrary large number of points.

Finite-Time Ruin Probabilities for Discrete, Possibly Dependent, Claim Severities [PDF]
This paper is concerned with the compound Poisson risk model and two generalized models with still Poisson claim arrivals. One extension incorporates inhomogeneity in the premium input and in the claim arrival process, while the other takes into account ...

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Inequalities for the ruin probability in a controlled discrete-time risk process [PDF]
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.

Advanced Functional Materials, EarlyView.ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

A numerical method for the expected penalty–reward function in a Markov-modulated jump–diffusion process. [PDF]
A generalization of the Cramér–Lundberg risk model perturbed by a diffusion is proposed. Aggregate claims of an insurer follow a compound Poisson process and premiums are collected at a constant rate with additional random fluctuation.

Advanced Functional Materials, EarlyView.P4bm framework in NaNbO3‐Ba(Ti, Hf)O3 ferrodistortive relaxor entails short‐range and highly‐polar ferrodistortive orders. The abundant highly‐polar orders facilitate to increase entropy change, and robust octahedral oxygen tilt enables to impede thermal perturbations.
