From Individual Stress Responses to Emergent Network Dynamics: The Conceptual Stress Propagation Model for Animal Groups

This paper introduces the Conceptual Stress Propagation Model (CSPM), a qualitative framework proposing that individual stress in group-housed animals aggregates into emergent network dynamics through social transmission pathways, supported by exploratory stakeholder perceptions and accompanied by specific, falsifiable predictions for future empirical validation.

Analysis of a Spatio-temporal Harvested Prey-Predator Model and a Machine Learning Framework for Prediction of Pattern Regimes with Demonstration on the Model

This paper investigates the spatio-temporal dynamics of a harvested prey-predator model with Holling Type-II functional response through analytical stability and bifurcation analysis, while simultaneously developing and validating a hybrid CNN-Random Forest machine learning framework to predict pattern regimes and construct transition diagrams across a two-parameter space.

Afadin Loss Uncovers an Ectopic Neurogenic Niche and Reorganizes the Adult Ventricular-Subventricular Zone

This study demonstrates that developmental loss of the adherens junction protein Afadin reorganizes the adult brain by inducing a stable, ectopic neurogenic niche in the neocortex and disrupting the canonical ventricular-subventricular zone, thereby revealing the profound plasticity of neural stem cells in response to adhesion defects.

Phytochemical Screening and Comparative Antimicrobial Activity of Phyllanthus niruri L. (Phyllanthaceae) against Staphylococcus aureus, Escherichia coli, and Candida albicans

This study validates the ethnomedicinal use of *Phyllanthus niruri* L. from Mozambique by demonstrating that its leaf extract, rich in phenols, flavonoids, and tannins, exhibits potent, dose-dependent antifungal activity against *Candida albicans* and *Staphylococcus aureus* (with MICs of 12.5 mg/mL), outperforming Fluconazole at higher concentrations, while showing no efficacy against *Escherichia coli*.

Rethinking Model Selection in Choice Behavior

Naoki Kamiya, who was affiliated with The Institute of Statistical Mathematics when the work reported in the manuscript was conducted and who now conducts research through Relations & Behavior Lab, Tokyo, Japan, argues for shifting the focus of choice behavior model selection from identifying a single "correct" formulation to evaluating how different models capture distinct manipulable environmental components, advocating for the use of ensemble methods like Bayesian model averaging and stacking to integrate these complementary structures for improved prediction and control.

Structure-Based Design of RNA Aptamers Targeting the Oncogenic KRAS G12D Variant

This study employs a comprehensive in silico approach to identify and characterize RNA-106, a stable RNA aptamer that selectively binds to and inhibits the oncogenic KRAS G12D variant through specific interactions with its Switch I and II domains, offering a promising foundation for developing RNA-based therapeutics against KRAS-driven cancers.

Brain Activity Related to Cheating Identification: A Step Towards the Study of Corruption

This study utilized an fMRI paradigm with INDETRAE scenarios to demonstrate that different cheating circumstances elicit distinct neural signatures across mentalizing, executive control, and reward networks, thereby validating the paradigm for investigating the neural substrates of corruption.
