Long-duration gamma-ray bursts (GRBs) are associated with type Ic supernovae that are more luminous than average and that eject material at very high velocities. Less-luminous supernovae were not hitherto known to be associated with GRBs, and therefore GRB-supernovae were thought to be rare events. Whether X-ray flashes--analogues of GRBs, but with lower(More)
Massive present-day early-type (elliptical and lenticular) galaxies probably gained the bulk of their stellar mass and heavy elements through intense, dust-enshrouded starbursts--that is, increased rates of star formation--in the most massive dark-matter haloes at early epochs. However, it remains unknown how soon after the Big Bang massive starburst(More)
BACKGROUND Increase of EGFR gene copy number consequent to gene amplification and/or polysomy of chromosome 7 has been significantly associated with better clinical outcome in Non Small Cell Lung Cancer (NSCLC) patients treated with Tyrosin-Kinase Inhibitors (TKIs).The primary method to detect EGFR copy number is FISH (Fluorescence in Situ Hybridization),(More)
– 2 – We use a large sample of Gamma-Ray Burst (GRB) afterglow and prompt emission data to compare the optical afterglows (or the lack thereof) of " short/hard " Type I GRBs (those that are assumed not to be due to the death of massive stars, but, e.g., merger of compact objects) with those of " long/soft " Type II GRBs (those due to the core collapse of(More)
Management of rhythm related issues might be particularly challenging in patients with congenital heart disease due to complex anatomy and restricted vascular access. The leadless technology appears a suitable and attractive alternative for this population. We describe a patient with single ventricle physiology who successfully underwent implantation of a(More)
Gamma-ray bursts (GRBs) are produced by rare types of massive stellar explosion. Their rapidly fading afterglows are often bright enough at optical wavelengths that they are detectable at cosmological distances. Hitherto, the highest known redshift for a GRB was z = 6.7 (ref. 1), for GRB 080913, and for a galaxy was z = 6.96 (ref. 2). Here we report(More)
AIMS An antiarrhythmic effect of spinal cord stimulation (SCS) has been recognized in an animal model. The actual mechanism is still mainly unknown. An adrenergic output reduction has been advocated as the main mechanism, although a modulation effect on the arrhythmic substrate has not yet been investigated. We studied T-wave alternans (TWA) modifications(More)
Magnetars are young neutron stars with very strong magnetic fields of the order of 10(14)-10(15) G. They are detected in our Galaxy either as soft gamma-ray repeaters or anomalous X-ray pulsars. Soft gamma-ray repeaters are a rare type of gamma-ray transient sources that are occasionally detected as bursters in the high-energy sky. No optical counterpart to(More)
