Are physiological oscillations physiological?
The Journal of Physiology, EarlyView., 2023 Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Supramolecular Chalcogen‐Bonded Shape Memory Actuators
Angewandte Chemie, EarlyView.Supramolecular chalcogen‐bonded liquid crystal elastomers incorporating Se⋯N interactions exhibit distinct shape memory and actuation properties. Stronger Se⋯N ChBs enable programmable one‐way and two‐way SME, while weaker S⋯N ChBs fail to induce actuation.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This study examines the complex dynamics of dengue transmission by incorporating time delay into a comprehensive model. The model is designed to capture several essential components, including steady‐state events, immune waning, recuperation from infection, and partial shielding in human populations.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.

Individuals Strategies and Predator–Prey Game Models in Deterministic and Random Settings
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The authors propose a new predator–prey game model by integrating two optional strategies into prey species: cooperative and isolation strategies. An investigation of the evolutionary impact on predator–prey system dynamics is given. The model utilizes a replicator equation to track changes in the frequency of cooperative strategy among preys,

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...

physica status solidi (RRL) – Rapid Research Letters, EarlyView.Reservoir computing with optical devices offers an energy‐efficient approach for time‐series forecasting. For quantum‐dot lasers with optical self‐feedback, the scattering timescale R into the quantum‐dot levels changes the predictive performance of the reservoir computer.

Kaldor, Hicks and Goodwin Meet the Supermultiplier: On Growth Cycles and Autonomous Demand
Metroeconomica, EarlyView.ABSTRACT This paper presents an approach to reconciling short‐run business cycles with long‐run growth in macroeconomic models. It addresses recent criticisms of supermultiplier models by developing a framework that combines investment‐driven cycles with autonomous demand‐led growth in the long run.

Quantitative Biology, Volume 13, Issue 3, September 2025.Abstract Critical transitions and tipping phenomena between two meta‐stable states in stochastic dynamical systems are a scientific issue. In this work, we expand the methodology of identifying the most probable transition pathway between two meta‐stable states with Onsager–Machlup action functional, to investigate the evolutionary transition dynamics ...

Estimates of Solutions for Integro‐Differential Equations in Epidemiological Modeling
Mathematical Methods in the Applied Sciences, Volume 48, Issue 10, Page 10533-10543, 15 July 2025.ABSTRACT Integro‐differential equations (IDE) have been applied in a variety of areas of research, including epidemiology. Recently, IDE systems were applied to study dengue fever transmission dynamics at the population level. In this study, we extend the approach presented in a previous study for describing the epidemiological model of dengue fever ...
