Advanced Science, EarlyView.This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Advanced Science, EarlyView.The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

The Study of Cable Behavior with Two Spring-Dampers and One Viscous Damper
, 2023 The objective of this research was to investigate the behavior of cables with two springs-damper and one viscous damper. To this end, a major mode is adopted to control the vibration of the cable. In this mode, two damping springs are connected to both ends of the cable. The purpose is to reduce the vibrations of the cable by placing a third damper. In

Viscous rotary vane actuator/damper [PDF]
, 1976 A compact viscous rotary actuator/damper for use on the Mariner '71 and Viking Programs was developed. Several functions were combined into this single mechanism to control the deployment, latching, and damping of the solar panel arrays used on these ...
