Cross‐scale Material‐Structure Synergy for 2D Metamaterials: Toward Customizable Intelligent Electromagnetic Manipulation in Multiphysics Fields

open access: yesAdvanced Science, EarlyView.
Recent advances in metasurface‐enabled low‐observable technologies are reviewed from the perspective of cross‐scale material–structure synergy. Electromagnetic, thermal, optical, and acoustic stealth are highlighted together with dynamic tuning, programmable coding, data‐driven inverse design, artificial intelligence, multispectral compatibility, and ...

Military Aviators, Special Operations Forces, and Causal Malaria Prophylaxis [PDF]

open access: yesMilitary Medicine, 2003
U.S. military aviators are currently restricted to the use of chloroquine or doxycycline for malaria prophylaxis. Ground forces are allowed the additional option of taking mefloquine. These medications are begun before deployment, must be taken for 4 weeks after leaving the malarious area, and primaquine must be added to the regimen the last 2 of those

Endowing Flexibility of Alveolar Type II Cells to Recapitulate Development From Lung Bud to Alveoli

open access: yesAdvanced Science, EarlyView.
Adult human alveolar type 2 cells are chemically reprogrammed into expandable alveolar progenitor‐like cells that acquire bud tip‐like features during expansion and form organoids that mature into alveolar‐like structures. These organoids model influenza A virus infection and innate immune responses in vitro, while transplanted cells engraft ...

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Orthogonal Light‐ and Enzyme‐Triggered and‐Gate Prodrugs for Senolytic Therapy

open access: yesAdvanced Science, EarlyView.
An orthogonal AND‐gate prodrug platform combines 390 nm near‐UV photocleavage with SA‐β‐gal activation to control payload release in senescent cells. Its modular architecture enables 4‐MU fluorescence, doxorubicin‐mediated cytotoxicity, and ARV‐771‐driven BRD4 degradation, supporting stimulus‐controlled senolytic design in cellular and organoid models.

Electrically Tuning Electromagnetic Wave Shielding in Phase Engineered 1T/2H‐MoS2‐Based Devices

open access: yesAdvanced Electronic Materials, EarlyView.
Sub‐millimeter‐thick phase‐engineered 1T/2H‐MoS2 structures enable electrically tunable electromagnetic interference shielding through active modulation of microwave absorption and reflection. The coexistence of metallic and semiconducting phases, combined with a PVA/KOH gel electrolyte, provides dynamic control over charge transport and interfacial ...

Integrating Reinforcement Learning With Explainable Artificial Intelligence for Real‐Time Clinical Decision Support in Dynamic Healthcare Environments

open access: yesAdvanced Intelligent Systems, EarlyView.
A hybrid Reinforcement Learning–Explainable AI framework integrates SHAP and LIME explanations directly into a Deep Q‐Network inference loop for real‐time ICU decision support. Trained on 18 142 mechanically ventilated stays from the eICU database, the system attains 93.0% decision accuracy, 20% fewer errors than RL alone, and a 91% clinician trust ...
