Acoustic stimulation for sleep enhancement and declarative memory: A systematic review and meta‐analysis

open access: yesSleep Research, EarlyView.
Abstract Background Acoustic stimulation is a non‐invasive neuromodulation approach with unclear efficacy for sleep and cognition across paradigms and populations. This meta‐analysis systematically evaluated its effects on sleep architecture and declarative memory. Methods We searched the PubMed, Web of Science, the Cochrane Library, Scopus, and Embase

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

open access: yesSmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

Intelligent Continuum Micromachines in Complex Confined Spaces

open access: yesSmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Polymersome‐Enabled Multimodal Delivery of Tobramycin and Doripenem for Targeted Eradication of Pseudomonas aeruginosa Biofilms in Chronic Rhinosinusitis

open access: yesSmall, EarlyView.
Schematic representation of diffusion‐based versus pH‐triggered drug release within a bacterial biofilm. In diffusion‐based systems, drug cargo is gradually released independent of local pH, resulting in rapid burst release and reduced sustained concentrations.

Fluorescence Sensing of Anions Like Adenosine 5ʹ‐Triphosphate With pH‐Gated Porous Dye‐Loaded Cerasomes

open access: yesSmall, EarlyView.
The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐
