Astrophysical parameters and orbital solution of the peculiar X-ray transient IGR J00370+6122 [PDF]

, 2014
BD+6073 is the optical counterpart of the X-ray source IGR J00370+6122, a probable accretion-powered X-ray pulsar. The X-ray light curve of this binary system shows clear periodicity at 15.7 d, which has been interpreted as repeated outbursts around the ...

X-ray variability during the quiescent state of the neutron-star X-ray transient in the globular cluster NGC 6440 [PDF]

, 2004
The globular cluster NGC 6440 is known to harbor a bright neutron-star X-ray transient. We observed the globular cluster with Chandra on two occasions when the bright transient was in its quiescent state in July 2000 and June 2003 (both observations were

Assessment of Artificial Intelligence Models for Estimating Lengths of Gradually Varied Flow Profiles

Complexity, 2021
The study of water surface profiles is beneficial to various applications in water resources management. In this study, two artificial intelligence (AI) models named the artificial neural network (ANN) and genetic programming (GP) were employed to ...

Discovery of the neutron star nature of SLX 1737-282

, 2002
SLX 1737-282 is a persistent moderately bright X-ray source 1.2 deg from the Galactic center. X-ray observations with the Wide Field Cameras on BeppoSAX have for the first time revealed the true nature of SLX 1737-282: a 15-min long thermonuclear flash ...

Sedimentation and Type I X-ray Bursts at Low Accretion Rates [PDF]

, 2006
Neutron stars, with their strong surface gravity, have interestingly short timescales for the sedimentation of heavy elements. Motivated by observations of Type I X-ray bursts from sources with extremely low persistent accretion luminosities, $L_X < 10 ...

Tenecteplase Versus Alteplase for First‐Pass Reperfusion in Basilar Artery Occlusion Stroke Thrombectomy

Annals of Neurology, EarlyView.
Objective The first‐pass effect (FPE), defined as excellent reperfusion after a single attempt, is associated with improved outcomes in large vessel occlusion stroke. We evaluated whether intravenous tenecteplase (TNK) compared with alteplase (TPA) increases the likelihood of FPE in basilar artery occlusion (BAO).

Environmental Dynamism and Supply Chain Responsiveness Nexus: Do Organisational Improvisation and Supply Chain Orientation Matter?

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The crucial role of environmental dynamism (ED) in achieving supply chain responsiveness (SCR) has become a controversial topic in extant literature. However, despite several empirical studies on environmental dynamism and supply chain responsiveness, inconsistent findings and underexplored areas leave supply chain managers less informed about
