Ruin probabilities with dependence on the number of claims within a fixed time window [PDF]
We analyse the ruin probabilities for a renewal insurance risk process with inter-arrival time distributions depending on the claims that arrived within a fixed (past) time window. This dependence could be explained through a regenerative structure.

This work shows that the fusion of InSb colloidal quantum dots (CQDs) leads to the formation of band‐tail trap states that are detrimental to the performance of optoelectronic devices. These results highlight the critical role of suppressing band‐tail trap states and passivating surface defects in enhancing device performance and motivate toward the ...

Robust estimation and inference for heavy tailed GARCH [PDF]
We develop two new estimators for a general class of stationary GARCH models with possibly heavy tailed asymmetrically distributed errors, covering processes with symmetric and asymmetric feedback like GARCH, Asymmetric GARCH, VGARCH and Quadratic GARCH.

Using Dopants as Agents to Probe Key Electronic Properties of Organic Semiconductors
Dopants are typically used in organic electronics to enhance conductivity, but here their potential is demonstrated as probes for fundamental material properties. By integrating experimental data and multiscale simulations, it is shown how dopant ionization and conductivity measurements enable accurate extraction of ionization potential and Coulomb ...

The Heavy-Tail Phenomenon in SGD
In recent years, various notions of capacity and complexity have been proposed for characterizing the generalization properties of stochastic gradient descent (SGD) in deep learning. Some of the popular notions that correlate well with the performance on

Abstract This study focuses on the extraction of nickel ions from an aqueous solution using a green emulsion liquid membrane (GELM). Its primary objective is to choose between corn oil and sunflower oil as a solvent in GELM and compare their performance with a kerosene‐based emulsion liquid membrane (ELM).

Black swans or dragon kings? A simple test for deviations from the power law [PDF]
We develop a simple test for deviations from power law tails, which is based on the asymptotic properties of the empirical distribution function. We use this test to answer the question whether great natural disasters, financial crashes or electricity ...

A new class of large claim size distributions: Definition, properties, and ruin theory [PDF]
We investigate a new natural class $\mathcal{J}$ of probability distributions modeling large claim sizes, motivated by the `principle of one big jump'. Though significantly more general than the (sub-)class of subexponential distributions $\mathcal{S}$, many important and desirable structural properties can still be derived.

This graphical abstract illustrates the steps carried out in the laboratory study, including saponin modification and characterization, surface tension, interfacial tension, contact angle, adsorption, and surfactant injection tests. Abstract In this study, three forms of saponin surfactants extracted from the Camellia sinensis plant (CS1, CS2, and CS3)

Robust estimator of distortion risk premiums for heavy-tailed losses [PDF]
We use the so-called t-Hill tail index estimator proposed by Fabi\'an(2001), rather than Hill's one, to derive a robust estimator for the distortion risk premium of loss.
