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.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

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.

Direct Method to Compute Doppler Beaming Factors in Binary Stars
The Astrophysical JournalThe Doppler beaming effect, induced by the reflex motion of stars, introduces flux modulations and serves as an efficient method to photometrically determine mass functions for a large number of close binary systems, particularly those involving compact ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
Advanced Engineering Materials, EarlyView.This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

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.

Advanced Engineering Materials, EarlyView.Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Beaming of particles and synchrotron radiation in relativistic magnetic reconnection
, 2016 Relativistic reconnection has been invoked as a mechanism for particle acceleration in numerous astrophysical systems. According to idealised analytical models reconnection produces a bulk relativistic outflow emerging from the reconnection sites (X ...
