On the Proper Treatment of Dynamics in Cognitive Science

Topics in Cognitive Science, Volume 18, Issue 3, July 2026.
Abstract This essay examines the relevance of dynamical ideas for cognitive science. On its own, the mere mathematical idea of a dynamical system is too weak to serve as a scientific theory of anything, and dynamical approaches within cognitive science are too rich and varied to be subsumed under a single “dynamical hypothesis.” Instead, after first ...

Freeform Manufacturing of Plant‐Based Structural Colors for Scalable Photonic and Mechanochromic Devices

Advanced Materials, Volume 38, Issue 35, 23 June 2026.
A green, freeform manufacturing approach that utilizes robust aqueous two‐phase systems to create intricate and scalable photonic structures and non‐planar mechanochromic hydrogel actuators from plant‐based hydroxypropyl cellulose. This approach broadens the structural possibilities of sustainable photonic devices and mechanochromic systems, offering ...

Turing instability in a modified cross-diffusion Leslie–Gower predator–prey model with Beddington–DeAngelis functional response

Boundary Value Problems, 2022
In this paper, a modified cross-diffusion Leslie–Gower predator–prey model with the Beddington–DeAngelis functional response is studied. We use the linear stability analysis on constant steady states to obtain sufficient conditions for the occurrence of ...

A Survey for Deep Reinforcement Learning Based Network Intrusion Detection

Applied AI Letters, Volume 7, Issue 2, June 2026.
This paper surveys deep reinforcement learning (DRL) for network intrusion detection, evaluating model efficiency, minority attack detection, and dataset imbalance. Findings show DRL achieves state‐of‐the‐art results on public datasets, sometimes surpassing traditional deep learning.

The Role of Inducible Defence in Ecological Models: Effects of Nonlocal Intraspecific Competition

Studies in Applied Mathematics, Volume 156, Issue 6, June 2026.
ABSTRACT Phenotypic plasticity significantly influences species interactions, especially via inducible defensive mechanisms in predator–prey dynamics. This work proposes and explores a predator–prey scenario whereby the prey species demonstrates inducible defence mechanisms against predators.

Bifurcation analysis in a diffusive predator–prey system with Michaelis–Menten-type predator harvesting

Advances in Difference Equations, 2018
In this paper, we consider a modified predator–prey model with Michaelis–Menten-type predator harvesting and diffusion term. We give sufficient conditions to ensure that the coexisting equilibrium is asymptotically stable by analyzing the distribution of

Quantifying the Uncertainty of Molecular Dynamics Simulations: Good–Turing Statistics Revisited

Journal of Computational Chemistry, Volume 47, Issue 14, 30 May 2026.
A method and associated computer program are described that allow the estimation of the remaining structural uncertainty of a molecular dynamics trajectory. ABSTRACT We have previously shown that Good–Turing statistics can be applied to molecular dynamics trajectories to estimate the probability of observing completely new (thus‐far unobserved ...

Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

Advanced Science, Volume 13, Issue 30, 28 May 2026.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

Turing instability and Hopf bifurcation in a predator–prey model with delay and predator harvesting

Advances in Difference Equations, 2019
In this paper, we study a predator–prey model with delay and harvesting on predator. We give the conditions for stability and Turing instability of coexisting equilibrium by analyzing the eigenvalue spectrum.
