Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT This communication discusses the application of implicit Runge–Kutta methods to constrained flexible multibody systems. Since the resulting systems of differential algebraic equations (DAEs) are typically considered to be very stiff, the family of stiffly accurate A$A$‐ and L$L$‐stable Radau IIA collocation methods is investigated.

On the Global Asymptotic Stability of an Infection‐Age‐Structured Competitive Model
Mathematical Methods in the Applied Sciences, Volume 49, Issue 17, Page 18040-18072, 30 November 2026.ABSTRACT We investigate an infection‐age‐structured competitive epidemiological model involving multiple strains. While classical results establish competitive exclusion when a unique maximal basic reproduction number exists, we provide here a complete characterization of the asymptotic behavior for an arbitrary number of populations without assuming ...

Engineering Reports, Volume 8, Issue 11, November 2026.Computational modeling of tumors is foundational in exploring cancer behavior, guiding clinical decision‐making, and assessing therapeutic impact in a controlled, predictive framework. While integer‐order models have been extensively explored in the past, innovative applications of fractional calculus to cancer‐immune system modeling remain largely ...

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3540-3560, November 2026.ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Computational Models of the Foreign Body Response: A Focus on Biomaterial Properties
Journal of Biomedical Materials Research Part A, Volume 114, Issue 11, November 2026.ABSTRACT The foreign body response (FBR) is the main biological process governing the long‐term performance and safety of implantable biomaterials. As the FBR is complex, multifactorial, and unfolds over extended time scales, making in vitro replication challenging, standard biological evaluation frameworks continue to rely primarily on in vivo testing

Traveling Fronts for (q,r)$(q, r)$‐Relativistic Operators: Existence and Asymptotic Properties
Mathematische Nachrichten, Volume 299, Issue 11, Page 3665-3688, November 2026.ABSTRACT A new reaction–diffusion model governed by a (q,r)$(q, r)$‐relativistic type diffusion, generalizing the p$p$‐relativistic one and encompassing singular and/or degenerate diffusivity, is introduced. In the monostable case, some existence results for (decreasing) fronts are then provided, exploiting the study of a suitable two‐point problem ...

Journal of Food Process Engineering, Volume 49, Issue 11, November 2026.A compact multispectral imaging system combined with a physics‐informed neural network enables real‐time quantitative monitoring and prediction of enzymatic browning in fresh‐cut apples. The Weibull‐constrained model improves temporal extrapolation over conventional Weibull and data‐driven neural network approaches.

An Optimal Control Framework for Multi‐Species Harvesting in the Southern Black Sea
Natural Resource Modeling, Volume 39, Issue 4, November 2026.ABSTRACT The management of marine fisheries requires balancing ecological sustainability with economic profitability, particularly in ecosystems vulnerable to overexploitation. This study develops a multi‐species optimal control modeling framework for the southern Black Sea, focusing on three key species: horse mackerel (Trachurus mediterraneus) as ...

Johnson–Schwartzman gap labeling for metric and discrete decorated graphs
Journal of the London Mathematical Society, Volume 114, Issue 5, November 2026.Abstract We study Schrödinger operators on metric and discrete decorated graphs. The values taken by the integrated density of states (IDS) on spectral gaps are called gap labels. A natural question is which gap labels can occur. We answer this for graphs arising from uniquely ergodic one‐dimensional dynamical systems by proving Johnson–Schwartzman gap‐

A Unified Block‐Modal Framework for Inverse Source Problems in Heat and Mass Transfer
International Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.ABSTRACT This work presents a unified block–modal framework for inverse source identification in linear diffusive problems arising in heat and mass transfer. Starting from a general parabolic model with mixed boundary operators, the Classical Integral Transform Technique is employed to project the dynamics onto an orthonormal eigenbasis, yielding a ...
