Discovering Interpretable Semantics from Radio Signals for Contactless Cardiac Monitoring

open access: yesAdvanced Science, EarlyView.
This study presents a semantic representation framework for clinically interpretable cardiac monitoring from contactless radio signals. It formulates radio semantic learning as an information‐bottleneck problem and approximates the objective via intra‐modal compression and cross‐modal alignment, structuring radio measurements into meaningful semantic ...

Employer Support for Employee Voluntarism [PDF]

open access: yes
This study uses the microdata from the 1997 National Survey of Giving, Volunteering and Participating (NSGVP) and from a comparable survey for 1987 to answer a number of key questions pertaining to the role of employers in support of employee voluntarism:

Bioinspired Cold‐Laminated Ultrathin Hydrogels as a Broadly Adaptive Platform for Physiological Monitoring

open access: yesAdvanced Science, EarlyView.
A cold‐lamination strategy is introduced to fabricate ultrathin, nanomesh‐reinforced hydrogel bioelectronics with controlled thickness, tunable mechanics, and reversible adhesion. By mechanically interlocking a TPU nanomesh within a temperature‐responsive hydrogel, the platform enables robust epidermal and implantable cardiac interfaces, supporting ...

Dual‐Strategy Design of Heterojunction‐Enhanced Piezoelectric Hydrogels for Periodontitis Treatment

open access: yesAdvanced Science, EarlyView.
This study developed a piezoelectric hydrogel integrating heterojunction enhancement and dual‐salt synergy, combining robust electrical performance with mechanical stability and bioactivity to better match the periodontal microenvironment. Under ultrasound activation, the hydrogel markedly promotes macrophage M2 polarization, thereby reducing the ...
