Heterogeneity in Short Gamma-ray Bursts [PDF]
, 2011 We analyze the Swift/BAT sample of short gamma-ray bursts, using an objective Bayesian Block procedure to extract temporal descriptors of the bursts' initial pulse complexes (IPCs). The sample comprises 12 and 41 bursts with and without extended emission (EE) components, respectively.

Semiconducting Open‐Shell Radicals for Precise Tumor Activatable Phototheranostics
Advanced Science, EarlyView.A versatile phototheranostics nanoplatform of tumor‐specific activatable semiconducting open‐shell radicals for precise chemodynamic/photodynamic therapy (CDT/PDT) guided by “Turn On” second near‐infrared (NIR‐II) window fluorescence imaging (FLI) and PA imaging (PAI) through molecular engineering strategies. Abstract Semiconducting open‐shell radicals

Multiwavelength Analysis of the Supernova-associated Low-luminosity GRB 171205A
The Astrophysical JournalMultiwavelength properties of the nearby supernova (SN)-associated low-luminosity GRB 171205A are investigated in depth to constrain its physical origin synthetically. The pulse width is found to be correlated with energy with a power-law index of −0.24 ±

Response of the Separated Flow over an Airfoil to Actuator Bursts [PDF]
arXiv, 2019 The separated flow response to single and multiple burst mode actuation over a 2-D airfoil at $12^o$ angle of attack was studied experimentally. For the single-burst actuation case, surface pressure signals were correlated with the flowfield observations of the roll-up and convection of a large-scale vortex structure that follows the actuator burst ...

GAMMA-RAY BURSTS ARE OBSERVED OFF-AXIS [PDF]
, 2014 We constrain the jet opening angle and, for the first time, the off-axis observer angle for gamma-ray bursts in the Swift-XRT catalog by using the ScaleFit package to fit afterglow light curves directly to hydrodynamic simulations.

Advanced Science, EarlyView.Targeted regulation of pyroptosis to modulate the immune landscape is a novel design strategy for cancer immunotherapy and anti‐inflammatory treatment. Pyroptosis, as a double‐edged sword, underscores the importance of optimizing the design strategy of functional materials and appropriately activating pyroptosis for the effective treatment of diseases.

Advanced Electronic Materials, EarlyView.All‐solution process technique is used to fabricate an ultraviolet photodetector based on the heterojunction with ZnO nanorod arrays/CuI@GO films structure. The property of CuI is modulated by the introduction of GO. The device with the hybrid CuI@GO hole transport layer obtains enhanced responsivity and detectivity together with the short response ...

Contribution of γ-Ray Burst Afterglow Emissions to the Isotropic Diffuse γ-Ray Background
The Astrophysical JournalThe isotropic diffuse γ -ray background (IGRB) serves as a fundamental probe of the evolution of the extreme Universe. Although various astrophysical sources have been proposed as potential contributors to the IGRB, the dominant population is still under
