Quantifying chaos and randomness in magnetar bursts [PDF]
arXiv, 2023 In this study, we explore the dynamical stability of magnetar bursts within the context of the chaos-randomness phase space for the first time, aiming to uncover unique behaviors compared to various astrophysical transients, including fast radio bursts (FRBs).

Strange Nonchaotic Bursting in A Quasiperiodially-Forced Hindmarsh-Rose Neuron [PDF]
J. Korean Phys. Soc. 57, 1356 (2010), 2011 We study the transition from a silent state to a bursting state by varying the dc stimulus in the Hindmarsh-Rose neuron under quasiperiodic stimulation. For this quasiperiodically forced case, a new type of strange nonchaotic (SN) bursting state is found to occur between the silent state and the chaotic bursting state.

Advanced Healthcare Materials, EarlyView.The limitations of existing clinical treatments highlight the need for a more comprehensive strategy for addressing infected diabetic wounds. A tri‐layered scaffold is developed to deliver therapeutics loaded in CuBDC and ZIF‐8 MOFs that are tailored to the requirements of deep‐infected diabetic wounds.

Thermal and Nonthermal Emission from a Peculiar Long-duration GRB 211211A
The Astrophysical Journal, 2023 Long-duration GRB 211211A that lacks a supernova emission even down to very stringent limits at such a low redshift z = 0.076 and is associated with kilonova emission, suggests that its physical origin is from a binary compact star merger. By reanalyzing

Gamma-Ray Burst Energetics [PDF]
The Astrophysical Journal, 1999 We estimate the fraction of the total energy in a Gamma-Ray Burst (GRB) that is radiated in photons during the main burst. Random internal collisions among different shells limit the efficiency for converting bulk kinetic energy to photons. About 1% of the energy of explosion is converted to radiation, in 10-1000 kev energy band in the observer frame ...

Advanced Materials, EarlyView.This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

GRB 200829A: External-shock Origin of the Very Early Prompt Emission?
The Astrophysical Journal, 2023 Long-duration GRB 200829A was detected by Fermi-GBM and Swift-BAT/XRT, and then rapidly observed by other ground-based telescopes. It has a weak γ -ray emission in the very early phase and is followed by a bright spiky γ -ray emission pulse.

Gamma-ray bursts from stellar mass accretion disks around black holes
, 1993 A cosmological model for gamma-ray bursts is explored in which the radiation is produced as a broadly beamed pair fireball along the rotation axis of an accreting black hole.

A UNIFIED PICTURE FOR LOW-LUMINOSITY AND LONG GAMMA-RAY BURSTS BASED ON THE EXTENDED PROGENITOR OF llGRB 060218/SN 2006AJ [PDF]
, 2015 The relation between long gamma ray bursts (LGRBs) and low-luminosity GRBs (llGRBs) is a long standing puzzle—on one hand their high energy emission properties are fundamentally different, implying a different gamma ray source, yet both are associated ...

Cosmology with gamma-ray bursts
Astronomical and Astrophysical Transactions, 2022 Gamma-ray bursts constitute one of the most fascinating and relevant phenomena in modern science, with strong implications for several fields of astrophysics, cosmology and fundamental physics. In this short review, I focus on the prospective key-role of GRBs for cosmology. Indeed, the huge luminosity, the redshift distribution extending at least up
