Concepts and methods in optimization of integrated LC VCOs [PDF]

, 2001
Underlying physical mechanisms controlling the noise properties of oscillators are studied. This treatment shows the importance of inductance selection for oscillator noise optimization. A design strategy centered around an inductance selection scheme is

Revisiting the “Stick‐Slip” Process via Magnetism‐Coupled Flexible Sensors with Bioinspired Ridge Architecture

Advanced Materials, EarlyView.
A sandwich‐like device for stick‐slip perception is developed, featuring a deformable bioinspired ridge layer with capability of lateral deformation and fast recovery. Coupled with magnetized functionality, the morphological transformation is capable to induce periodical electrical pulses which allows to revisit the stick‐slip process when human ...

Durable Proton Exchange Membrane Based on Polymers of Intrinsic Microporosity for Fuel Cells

Advanced Materials, EarlyView.
A novel composite proton exchange membrane (PEM) design that leverages carboxylic acid‐functionalized polymers of intrinsic microporosity (cPIM‐1) and polyvinylpyrrolidone (PVP). Harnessing Lewis acid‐base interactions enables the development of a synergistic microporous structure that confines phosphoric acid clusters, enhancing proton conductivity ...

Different coding characteristics between flight and freezing in dorsal periaqueductal gray of mice during exposure to innate threats

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 491-501, December 2022., 2022
Flight and freezing are two vital defensive behaviors in the process of avoiding natural enemies in mice. We investigated the neural activity in dPAG nuclei of mice under two defensive behaviors, and found different coding features between flight and freezing behaviors. Abstract Background Flight and freezing are two vital defensive behaviors that mice
