ChemistryEurope, Volume 4, Issue 4, April 2026.The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Nonlocal Approximation of Slow and Fast Diffusion
Journal of Differential EquationsMotivated by recent work on approximation of diffusion equations by deterministic interacting particle systems, we develop a nonlocal approximation for a range of linear and nonlinear diffusion equations and prove convergence of the method in the slow, linear, and fast diffusion regimes.

An integrated framework to identify and characterize regional‐scale insect dispersal
Ecological Applications, Volume 36, Issue 3, April 2026.Abstract Forest pest insects cause major socio‐economic impacts, global losses of millions of dollars, and ecosystem changes. A key challenge for their management is tracing regional dispersal events critical to outbreak dynamics. We developed an integrated tracing framework for pest insects by combining isotope geolocation, ecological data, and ...

Evidence of negative density‐dependent dispersal in an invasive forest pest
Ecosphere, Volume 17, Issue 4, April 2026.Abstract Understanding the mountain pine beetle's dispersal patterns is critical for evaluating its threat to Canada's boreal forests. It is generally believed that higher beetle densities lead to increased long‐distance dispersal. One possible explanation is that beetle aggregation pheromones become repellent at high concentrations, causing beetles to

Maximum principles, sliding techniques and applications to nonlocal equations
Electronic Journal of Differential Equations, 2007 This paper is devoted to the study of maximum principles holding for some nonlocal diffusion operators defined in (half-) bounded domains and its applications to obtain qualitative behaviors of solutions of some nonlinear problems.

Mott–Schottky Analysis of Archaeological Etruscan Pottery
Electroanalysis, Volume 38, Issue 4, April 2026.Mott–Schottky plots of the inverse of the square of capacitance versus applied potential is used to study archaeological pottery from the Etruscan site of Pyrgi in Santa Severa (Rome, Italy). The application of Mott–Schottky (MS) analysis to electrochemical impedance data recorded for microparticulate deposits of archaeological ceramic materials is ...

Well-posedness of elliptic-parabolic differential problem with integral condition
Қарағанды университетінің хабаршысы. Математика сериясыIn this paper, we study a class of nonlocal boundary value problems for elliptic-parabolic equations subject to integral-type conditions. Such problems naturally emerge in various physical and engineering contexts, including diffusion processes in ...
