Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors
Advanced Science, EarlyView.Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

A compact ultra wideband bandpass filter using arrow coupled lines with defected ground structure
Journal of Electrical Systems and Information Technology, 2014 A new ultra wideband bandpass filter (UWB-BPF) using arrow coupled lines and U-slot defected ground structures (U-DGS) is proposed. The input and output feeding lines are connected to the coupled lines placed on the conductor side of the substrate while ...

Rigid Hollow Microparticles for Enhanced Focused Ultrasound Treatment Under Optoacoustic Guidance
Advanced Science, EarlyView.By combining focused ultrasound (FUS) and acoustically active hollow borosilicate microparticles (HBMPs), we demonstrate tunable control over interparticle dynamics and their localized thermal energy deposition. Modulation of acoustic frequency and particle concentration tailors the energy delivery, allowing adaptive, material‐based regulation of ...
