The Effect of a Threshold Proportional Reinsurance Strategy on Ruin Probabilities [PDF]
In the context of a compound Poisson risk model, we define a threshold proportional reinsurance strategy: A retention level k1 is applied whenever the reserves are less than a determinate threshold b, and a retention level k2 is applied in the other case.

Advanced Technologies for Characterizing and Detecting Battery Thermal Failure: A Review
Advanced Science, EarlyView.Illustration of advanced characterization techniques to predict battery thermal failure. ABSTRACT Energy storage is essential in accelerating the global transition toward clean and sustainable energy across various sectors. Lithium‐ion batteries (LIBs) have become increasingly significant for energy storage due to their high energy density, low ...

Ruin Probabilities with Investments in Random Environment: Smoothness
MathematicsThis paper deals with the ruin problem of an insurance company investing its capital reserve in a risky asset with the price dynamics given by a conditional geometric Brownian motion whose parameters depend on a Markov process describing random ...

The win-first probability under interest force [PDF]
In a classical risk model under constant interest force, we study the probability that the surplus of an insurance company reaches an upper barrier before a lower barrier. We define this probability as win-first probability.

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction
Advanced Science, EarlyView.The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.

Optimal cash holding model based on minimization of ruin probability
Miskolc Mathematical NotesThe management of optimal cash holding is particularly important for the sustainability of enterprises’ survival and business decision-making. It is not good for enterprises to have more or less cash holding.
