Novel Gas Sensor Signal Acquisition Method: Amplifying Sensor Signals and Enabling Efficient Gas Identification

Advanced Science, EarlyView.
This study presents a novel method to improve sensitivity and gas identification in resistive gas sensors by dividing operation into reaction and signal detection phases. The reaction phase optimizes chemisorption, while the signal detection phase, using a read‐bias technique, enhances sensitivity.

Homocysteine Promotes the Pathogenesis of Atherosclerosis through the Circ‐PIAS1‐5/miR‐219a‐2‐3p/TEAD1 Axis

Advanced Science, EarlyView.
A model is schematically represented for the major molecular mechanisms by which homocysteine (Hcy) accelerates the nuclear export of circ‐PIAS1‐5, which regulates atherosclerosis by acting as a competing endogenous RNA for miR‐219a‐2‐3p. Hcy enrichment of circ‐PIAS1‐5 leads to YTHDC1 binding to circ‐PIAS1‐5 and promotes its intracellular localization ...

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities

Advanced Science, EarlyView.
This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal
