Capacity‐Learning Paradox: How Hong Kong and Singapore's Crisis Responses Shape and Are Shaped by Policy Capacities

open access: yesReview of Policy Research, Volume 43, Issue 2, March 2026.
ABSTRACT This study examines the paradoxical relationship between policy learning and capacity: governments need certain capacities to learn effectively, yet these same capacities often emerge from previous learning experiences. Through a comparative analysis of Hong Kong and Singapore's responses to SARS and COVID‐19, we demonstrate how policy ...

Guanidinium Like‐Charge Ion Pairing and Oligoarginine Aggregation in Water by Nuclear Magnetic Resonance, Cryo‐Electron Microscopy, and Molecular Dynamics

open access: yesAggregate, Volume 7, Issue 2, February 2026.
This study shows that guanidinium cations weakly attract one another in water and form like‐charge contact ion pairs. From NMR, we determine the free energy of ion‐pair formation to be ≈${\approx }$ –0.5 kJ mol−1${\rm mol}^{-1}$, consistent with all‐atom MD simulations and DFT calculations.

A Hybrid Framework for Stock Price Forecasting Using Metaheuristic Feature Selection Approaches and Transformer Models Enhanced by Temporal Embedding and Attention Pruning

open access: yesApplied AI Letters, Volume 7, Issue 1, February 2026.
Workflow of the proposed hybrid BWO‐Transformer framework for stock price prediction. ABSTRACT Accurately predicting stock prices remains a major challenge in financial analytics due to the complexity and noise inherent in market data. Feature selection plays a critical role in improving both computational efficiency and predictive performance. In this

T1‐weighted fMRI in mouse visual cortex using an iron oxide nanoparticle contrast agent and UTE imaging at 9.4 T

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 680-692, February 2026.
Abstract Purpose This study aims to investigate the feasibility of using T1‐weighted fMRI with an iron oxide nanoparticle contrast agent and UTE imaging at 9.4 T to measure functional hyperemia in the mouse visual cortex. The goal is to capture positive signal changes in both the parenchyma and pial surface, and to test whether surface vessels respond ...
