2D Abrupt Nano‐Junctions Blending sp–sp2 Bonds on Atomically Precise Heterostructures
Advanced Materials, EarlyView.A lateral heterostructure between atomically precise sp–sp2$^2$ metalated graphdiyne and sp2$^2$ graphene nanoribbons is realized by on‐surface synthesis and investigated by STM and DFT. The impact of on‐surface synthesis byproducts on covalent junction formation yield is unveiled.

Statistical analysis of mixtures underlying probability of ruin
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2009 If the hypothesis on exponentially distributed claims in a risk (or surplus) model is untenable then, in many cases, the assumption that they are mixtures of two (or more) exponentials is a suitable substitute.

A new De Vylder type approximation of the ruin probability in infinite time [PDF]
In this paper we introduce a generalization of the De Vylder approximation. Our idea is to approximate the ruin probability with the one for a different process with gamma claims, matching first four moments.

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes
Advanced Materials, EarlyView.This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

Parisian ruin probability for Markov additive risk processes
Advances in Difference Equations, 2018 In this paper, we consider a spectrally negative Markov additive risk process. Using the theory of Jordan chain, a compact formula of Parisian ruin probability is given.

Calculating multivariate ruin probabilities via Gaver–Stehfest inversion technique. [PDF]
Multivariate characteristics of risk processes are of high interest to academic actuaries. In such models, the probability of ruin is obtained not only by considering initial reserves u but also the severity of ruin y and the surplus before ruin x.

Advanced Materials, EarlyView.Intrinsic material dynamics are harnessed as computational resources for neuromorphic in‐materio physical reservoir computing. Defects, ionic motion, interfaces, percolation, geometry, and biasing shape transient states that provide fading memory, nonlinearity, and high‐dimensional projection for simple readout. A descriptor‐to‐dynamics framework links

PRECISE ESTIMATES OF RUIN PROBABILITIES
Quantitative Methods in Economics, 2015 In this paper we investigate a sequence of accurate approximations of ruin probabilities in discrete time models. We prove its convergence to the exact ruin probability without any restrictive assumptions on the claim distribution. Numerical studies show

Ruin probability analysis in geometric inhomogeneous claims case
Lietuvos Matematikos Rinkinys, 2011 The discrete time risk model with inhomogeneous claims is analyzed. The finite time ruin probability expression is obtained for the case when claims are distributed by geometric distribution with changing parameters.

Finite time ruin probabilities with one Laplace inversion. [PDF]
In this work we present an explicit formula for the Laplace transform in time of the finite time ruin probabilities of a classical Levy model with phase-type claims. Our result generalizes the ultimate ruin probability formula of Asmussen and Rolski [IME
