Reverse Shock Emission from Short GRBs

open access: yesGalaxies, 2018
We investigate the expected radio emission from the reverse shock of short GRBs, using the fitted afterglow parameters. In light of recent results suggesting that in some cases the radio afterglow is due to emission from the reverse shock, we examine the

The birth of black holes: neutron star collapse times, gamma-ray bursts and fast radio bursts [PDF]

open access: yes, 2014
Recent observations of short gamma-ray bursts (SGRBs) suggest that binary neutron star (NS) mergers can create highly magnetised, millisecond NSs. Sharp cut-offs in X-ray afterglow plateaus of some SGRBs hint at the gravitational collapse of these ...

Facile Fabrication of Large‐Area and High‐Quality Organic–Inorganic Hybrid Perovskite Ferroelectric Films Through Electrohydrodynamic Printing

open access: yesAdvanced Science, EarlyView.
In situ fabrication of large‐area, high‐quality organic‐inorganic hybrid perovskite ferroelectric (OIHPF) crystals and films via on‐demand electrohydrodynamic (EHD) printing modes. Abstract Traditional oxide ferroelectrics have long struggled to produce flexible, large‐area, and high‐quality thin films at low temperatures, despite their good ...

Hepatitis B virus movement through the hepatocyte: An update

open access: yesBiology 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.

Constructing Large‐Area Oriented Covalent Organic Framework Based PN Heterostructure Films to Enhance Artificial Photosynthesis of H2O2

open access: yesAngewandte Chemie, EarlyView.
We propose for the first time the concept of organic‐inorganic hybrid oriented PN heterostructured films to modulate the photocatalytic performance by constructing COF‐based PN heterostructured films, and our mechanistic studies confirm that oriented TAPB‐DMTA COFs based on thin films of PN heterostructures can provide the driving force to enhance the ...

Decameter Type III-Like Bursts [PDF]

open access: yesYSC'14 Proceedings of Contributed Papers (eds. G. Ivashchenko, A. Golovin), Kyiv, Kyivskyi Universytet, pp. 68-72, 2007, 2007
Starting from 1960s Type III-like bursts (Type III bursts with high drift rates) in a wide frequency range from 300 to 950MHz have been observed. These new bursts observed at certain frequency being compared to the usual Type III bursts at the same frequency show similar behaviour but feature frequency drift 2-6 times higher than the normal bursts.

Thermonuclear (type-I) X-ray bursts observed by the Rossi X-ray Timing Explorer [PDF]

open access: yes, 2006
We have assembled a sample of 1187 thermonuclear (type-I) X-ray bursts from 48 accreting neutron stars by the Rossi X-ray Timing Explorer, spanning more than ten years. The sample contains examples of two of the three theoretical ignition regimes and likely examples of the third.

LOCALIZATION OF GAMMA-RAY BURSTS USING THE FERMI GAMMA-RAY BURST MONITOR [PDF]

open access: yes, 2014
The Fermi Gamma-ray Burst Monitor (GBM) has detected over 1400 gamma-ray bursts (GRBs) since it began science operations in 2008 July. We use a subset of over 300 GRBs localized by instruments such as Swift, the Fermi Large Area Telescope, INTEGRAL, and ...

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

open access: yesAdvanced 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.

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

open access: yesBiological 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.
