Experimental and Numerical Analysis of Rock Burst Tendency and Crack Development Characteristics of Tianhu Granite

open access: yesGeofluids, 2021
Rock burst is a serious nonlinear dynamic geological hazard in underground engineering construction. In this paper, a true triaxial unloading rock burst experiment and numerical simulation are carried out on Tianhu granite to investigate the rock burst ...

Type-I bursts within outbursts of IGR J17473-2721 [PDF]

open access: yes, 2010
Two outbursts were observed by RXTE in the history of the atoll source IGR J17473-2721. During the most recent outburst in 2008, the source showed a complete series of spectral states/transitions.

Impact of Fuzzy Offset Time on Delay and Burst Loss Ratio for Optical Burst Switching Networks

open access: yesInternational Journal of Engineering and Advanced Technology, 2023
Optical burst switching (OBS) is an optical switching technology; it uses an optical fiber's high bandwidth potential to transfer huge amounts of data in the form of huge packets, which are more commonly referred to as bursts. High burst loss brought on by numerous burst contentions is a significant problem in OBS.

SELECTION EFFECTS IN GAMMA-RAY BURST CORRELATIONS: CONSEQUENCES ON THE RATIO BETWEEN GAMMA-RAY BURST AND STAR FORMATION RATES [PDF]

open access: yesThe Astrophysical Journal, 2015
Gamma-ray bursts (GRBs) visible up to very high redshift have become attractive targets as potential new distance indicators. It is still not clear whether the relations proposed so far originate from an unknown GRB physics or result from selection effects.

GRB 050911: a black hole - neutron star merger or a naked GRB [PDF]

open access: yes, 2005
GRB 050911, discovered by the Swift Burst Alert Telescope, was not seen 4.6 hr later by the Swift X-ray Telescope, making it one of the very few X-ray non-detections of a Gamma-Ray Burst (GRB) afterglow at early times.

Relationship between the peroxidation of leukocytes index ratio and the improvement of postprandial metabolic stress by a functional food [PDF]

open access: yes, 2015
For the first time, we investigated the relationship between postprandial dysmetabolism and the Peroxidation of Leukocytes Index Ratio (PLIR), a test that measures the resistance of leukocytes to exogenous oxidative stress and their functional capacity ...

Redshifts and Luminosities for 112 Gamma Ray Bursts [PDF]

open access: yes, 2001
Two different luminosity indicators have recently been proposed for Gamma Ray Bursts that use gamma-ray observations alone. They relate the burst luminosity (L) with the time lag between peaks in hard and soft energies, and the spikiness or variability ...

Design and Implementation of Burst Buffer Over-Subscription Scheme for HPC Storage Systems

open access: yesIEEE Access, 2023
Burst Buffer is widely used in supercomputer centers to bridge the performance gap between computational power and the high-performance I/O systems. The primary role of Burst Buffer is to temporarily absorb the bursty I/O and reduce the heavy access on ...

Classifying LISA gravitational wave burst signals using Bayesian evidence

open access: yes, 2010
We consider the problem of characterisation of burst sources detected with the Laser Interferometer Space Antenna (LISA) using the multi-modal nested sampling algorithm, MultiNest.

X-ray Flashes or soft Gamma-ray Bursts? The case of the likely distant XRF 040912 [PDF]

open access: yes, 2006
In this work, we present a multi-wavelength study of XRF 040912, aimed at measuring its distance scale and the intrinsic burst properties. We performed a detailed spectral and temporal analysis of both the prompt and the afterglow emission and we ...
