Text Mining in Bibliometrics and Science Mapping: A Methodological Review
WIREs Computational Statistics, Volume 18, Issue 2, June 2026.Text mining has become a foundational component of contemporary bibliometrics and science mapping, enabling systematic analysis of the semantic structure, thematic evolution, and cognitive organization of scientific fields. Integrating textual evidence with relational indicators enriches knowledge maps and supports more comprehensive, content‐sensitive

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Rainfall nowcasting, the short‐term prediction of precipitation, is a vital component of early warning systems aimed at mitigating the effects of extreme weather events. In this study, we develop a deep learning approach based on convolutional neural networks (CNNs) for rainfall nowcasting and train it exclusively on data from rain gauge ...

International Journal of Robust and Nonlinear Control, Volume 36, Issue 8, Page 4717-4728, 25 May 2026.ABSTRACT A newly developed robust control strategy based on an adaptive neural network (ANN) estimator performed in concert with adaptive super‐twisting (ASTW) control is presented. The proposed adaptive robust control algorithm is applied to a class of perturbed nonlinear systems and features a significantly decreased control gain with respect to the ...

Electronic Journal of Differential Equations, 2015 The authors consider a discontinuous planar autonomous system of differential equations having the following properties: (i) the system is linear in two domains \(G_1\) and \(G_2\) of the plane; its matrix has complex eigenvalues \(\gamma_1\pm i\omega_1\) with \(\gamma_1>0\) in \(G_1\) and complex eigenvalues \(\gamma_2\pm i\omega_2\) with ...

Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 5897-5912, 15 May 2026.ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...

Analysis of a Mathematical Model of Marital Satisfaction
Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 6143-6157, 15 May 2026.ABSTRACT A large number of marriages end in divorce. In this paper, we present a model for the emotional state of a couple based on bilinear ordinary differential equations. We study the effect of changes of each individual's self‐emotional state on the couple's state.

Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1179-1202, May 2026.ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 5, May 2026.ABSTRACT Although time‐varying Cox regression modeling approaches have been developed, exposure–response analyses for time‐to‐event (TTE) endpoints often rely on static exposure covariates and may overlook the real‐world dosing variability and drug concentration fluctuations over time. To better characterize pharmacokinetic (PK) or pharmacodynamic (PD)
