Asymptotic Expected Utility of Dividend Payments in a Classical Collective Risk Process

open access: yesRisks, 2023
We find the asymptotics of the value function maximizing the expected utility of discounted dividend payments of an insurance company whose reserves are modeled as a classical Cramér risk process, with exponentially distributed claims, when the initial ...

Record linkage of claims and cancer registries data—Evaluation of a deterministic linkage approach based on indirect personal identifiers

open access: yesPharmacoepidemiology and Drug Safety, Volume 31, Issue 12, Page 1287-1293, December 2022., 2022
Abstract Purpose In Germany, record linkage of claims and cancer registry data is cost‐ and time‐consuming, since up until recently no unique personal identifier was available in both data sources. The aim of this study was to evaluate the feasibility and performance of a deterministic linkage procedure based on indirect personal identifiers included ...

Stieltjes integral boundary value problem involving a nonlinear multi-term Caputo-type sequential fractional integro-differential equation

open access: yesAIMS Mathematics, 2023
In this article, we analyze the existence and uniqueness of mild solution to the Stieltjes integral boundary value problem involving a nonlinear multi-term, Caputo-type sequential fractional integro-differential equation.

An introduction to causal inference for pharmacometricians

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 12, Issue 1, Page 27-40, January 2023., 2023
Abstract As formal causal inference begins to play a greater role in disciplines that intersect with pharmacometrics, such as biostatistics, epidemiology, and artificial intelligence/machine learning, pharmacometricians may increasingly benefit from a basic fluency in foundational causal inference concepts.

On the Connections of Generalized Entropies With Shannon and Kolmogorov–Sinai Entropies

open access: yesEntropy, 2014
We consider the concept of generalized Kolmogorov–Sinai entropy, where instead of the Shannon entropy function, we consider an arbitrary concave function defined on the unit interval, vanishing in the origin.

Modelling the phenological development of cv. Touriga Nacional and Encruzado in the Dão Wine Region, Portugal

open access: yesOENO One, 2021
The grapevine vegetative cycle, which is morphologically described by its phenological stages, is strongly determined by weather conditions. Phenological models are widely applied in viticulture and are based on the assumption that air temperature is the

2019 Mw 6.0 Mesetas (Colombia) Earthquake Sequence: Insights From Integrating Seismic and Morphostructural Observations

open access: yesEarth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract The boundary between the Northern Andean block and the South American plate is a first‐order tectonic structure in Colombia with historically M > 7 earthquakes. However, details about individual sections of the system remain unknown. We illuminate the seismotectonic of the Algeciras fault by investigating an earthquake sequence that started on

A Proper Use of the Adjacent Land‐Based Observatory Magnetic Field Data to Account for the Geomagnetic Disturbances During Offshore Directional Drilling

open access: yesSpace Weather, Volume 20, Issue 12, December 2022., 2022
Abstract Directional drilling in the oil fields relies particularly on the “on‐fly” measurements of the natural magnetic field (measurements while drilling; MWD); the MWD are eventually used to construct the well path. These measurements are the superposition of the signals from the internal, core and crustal, and external, ionospheric and ...
