Proton Synchrotron Origin of the Very-high-energy Emission of GRB 190114C
The Astrophysical Journal, 2023 We consider here a proton-synchrotron model to explain the MAGIC observation of GRB 190114C afterglow in the energy band of 0.2–1 TeV, while the X-ray spectra are explained by electron-synchrotron emission.

Exact versus approximate beaming formulas in Gamma-Ray Burst afterglows [PDF]
, 2006 We present the exact analytic expressions to compute, assuming the emitted Gamma-Ray Burst (GRB) radiation is not spherically symmetric but is confined into a narrow jet, the value of the detector arrival time at which we start to "see" the sides of the ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Gamma Ray Burst Beaming Constraints from Afterglow Light Curves: GRB 970508
, 1999 The beaming angle (zeta) is the main uncertainty in gamma ray burst energy requirements today. We summarize predictions for the light curves of beamed bursts, and model the R band light curve of GRB 970508 to derive zeta > 30 degrees.

Molecular Oncology, EarlyView.A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

Quasi-periodic Oscillations in the X-ray Light Curves from Relativistic Tori [PDF]
, 2005 We use a relativistic ray-tracing code to analyze the X-ray emission from a pressure-supported oscillating relativistic torus around a black hole. We show that a strong correlation exists between the {\it intrinsic} frequencies of the torus normal modes ...

FEL options for power beaming [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998 Abstract We discuss the critical issues in designing an FEL–accelerator system for power beaming application and present several possible schemes.

PACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2002 The fixed target experiment E-158 has been running with an electron beam close to the highest possible charge and energy available at the Stanford Linear Accelerator Center (SLAC). A charge of 2.5/spl middot/10/sup 11/ electrons per pulse at 45 GeV and 30 Hz was routinely delivered for the E-158 commissioning run in April and May, 2001.
