WIREs Data Mining and Knowledge Discovery, Volume 13, Issue 1, January/February 2023., 2023 Performance of GAMLSS against some machine learning algorithms. Abstract The advent of technological developments is allowing to gather large amounts of data in several research fields. Learning analytics (LA)/educational data mining has access to big observational unstructured data captured from educational settings and relies mostly on unsupervised ...

Energy Science &Engineering, EarlyView.ABSTRACT Conducting an inquiry into the structural, mechanical, electrical, and optical aspects of Ge‐based InGeX3 (Cl, Br, and I) halide perovskites using the density functional theory approach is the main objective of this study. The investigation reveals that substituting the bigger halogen atoms (Br and I) with the smaller halide (Cl) enhances the ...

Stochastic homogenization on perforated domains II – Application to nonlinear elasticity models
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 102, Issue 12, December 2022., 2022 Abstract Based on a recent work that exposed the lack of uniformly bounded W1,p→W1,p$W^{1,p}\rightarrow W^{1,p}$ extension operators on randomly perforated domains, we study stochastic homogenization of nonlinear p‐elasticity, 1

Processes and Predictions in Ecological Models: Logic and Causality
Journal of Forecasting, EarlyView.ABSTRACT To make credible ecological predictions for terrestrial ecosystems in a changing environment and increase our understanding of ecological processes, we need plant ecological models that can be fitted to spatial and temporal ecological data.

Tectonics, Volume 41, Issue 12, December 2022., 2022 Abstract Large magnitude (Mw ∼ ≥6) earthquakes in extensional settings are often associated with simultaneous rupture of multiple normal faults as a result of static and/or dynamic stress transfer. Here, we report details of the coseismic breaching of a previously unrecognized large‐scale fault relay zone in central Greece, through three successive ...

Semilinear problems with bounded nonlinear term
Boundary Value Problems, 2005 We solve boundary value problems for elliptic semilinear equations in which no asymptotic behavior is prescribed for the nonlinear term.

Deterministic submanifolds for the backward‐evolving quantum state concerning a monitored qubit
IET Control Theory &Applications, Volume 17, Issue 1, Page 92-97, January 2023., 2023 Abstract The evolution of a quantum system subject to continuous weak measurement is described by a stochastic differential equation (SDE). It has been shown that the conventional density matrix ρt$\rho _t$ characterized by such SDE, under experimentally relevant settings, remains within a deterministically evolving manifold of low dimension, whose ...
