Evidence for a Canonical Gamma-Ray Burst Afterglow Light Curve in the Swift XRT Data [PDF]

, 2005
We present new observations of the early X-ray afterglows of the first 27 gamma-ray bursts (GRBs) well observed by the Swift X-Ray Telescope (XRT). The early X-ray afterglows show a canonical behavior, where the light curve broadly consists of three ...

Radio‐Activated Selenium‐Doped Janus Ag/Ag2SexSy Nanoparticles for Precise Cancer NIR‐II Fluorescence Imaging and Radiosensitization Therapy

Advanced Science, EarlyView.
A new kind of selenium‐doped Ag/Ag2S Janus nanoparticles (Ag/Ag2SexSy JNPs) is reported as radio‐responsive probes for specifically hydrogen peroxide (H2O2)‐activated cancer imaging and enhanced radiosensitization, offering a promising approach for precision cancer theranostics.

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 ...

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

Hepatitis B virus movement through the hepatocyte: An update

Biology of the Cell, Volume 114, Issue 12, Page 325-348, December 2022., 2022
Model of intracellular trafficking routes of progeny hepatitis B virus (HBV) viral and subviral particles through the liver cell involving nucleocytoplasmic shuttling, movement through the ER/Golgi secretory pathway, and budding and release through the multivesicular body (MVB) and/or secretory autophagosomes (sAP) axis.

Propagation of Gamma-Ray Burst Relativistic Jets in Active Galactic Nucleus Disks and Its Implication for Gamma-Ray Burst Detection

The Astrophysical Journal
The accretion disks of supermassive black holes (SMBHs) harboring in active galactic nuclei (AGN) are considered to be an ideal site for producing different types of gamma-ray bursts (GRBs). The detectability of these GRB phenomena hidden in AGN disks is

Functional Materials Targeted Regulation of Gasdermins: From Fundamentals to Functionalities and Applications

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.

The early diversification of ray‐finned fishes (Actinopterygii): hypotheses, challenges and future prospects

Biological Reviews, Volume 98, Issue 1, Page 284-315, February 2023., 2023
ABSTRACT Actinopterygii makes up half of living vertebrate diversity, and study of fossil members during their Palaeozoic rise to dominance has a long history of descriptive work. Although research interest into Palaeozoic actinopterygians has increased in recent years, broader patterns of diversity and diversity dynamics remain critically understudied.
