ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

Advanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Electron Transport in Quantum Dot Light‐Emitting Diodes

Advanced Electronic Materials, EarlyView.
This work reveals that electron transport in core/multi‐shell quantum dots is severely hindered by traps located at the core‐shell interface. These traps follow a Gaussian energy distribution with a density of approximately 1023 m−3 and a common energy level of 4.0 eV below the vacuum level.

Optimizing Decision Tree Attack on CAS Scheme

Advances in Electrical and Computer Engineering, 2016
In this paper we show a successful side-channel timing attack on a well-known high-complexity cognitive authentication (CAS) scheme. We exploit the weakness of CAS scheme that comes from the asymmetry of the virtual interface and graphical layout which
