On the Bardeen-Petterson Effect in black hole accretion discs

, 2015
We investigate the effect of black hole spin on warped or misaligned accretion discs - in particular i) whether or not the inner disc edge aligns with the black hole spin and ii) whether the disc can maintain a smooth transition between an aligned inner ...

Effect of grain disorientation on early fatigue crack propagation in face-centred-cubic polycristals: A three-dimensional dislocation dynamics investigation [PDF]

, 2013
Three-dimensional dislocation dynamics simulations are used to study micro-crack interaction with the first micro-structural barrier in face-centred cubic bi-crystals loaded in high cycle fatigue conditions. In the examined configuration, we assumed that

Pediatric Syncope: An Examination of Diagnostic Processes, Therapeutic Approaches and the Role of the Tilt Test: Insights from an 18-Year Single-Center Experience

Children
Objectives: Syncope is a common cause of the transient loss of consciousness, with neurally mediated syncope (NMS) and particularly vasovagal syncope (VVS) being the most prevalent types among older children and adolescents.

Age and the head-up tilt test outcome in syncope patients

Research in Cardiovascular Medicine, 2015
Background: The head-up tilt test (HUTT) is a useful diagnostic tool for syncope. Objectives: We sought to investigate the outcome of the HUTT in syncope patients and identify the relationship between age and different hemodynamic outcomes.

Orthostatic symptoms does not always manifest during tilt-table test in pediatric postural orthostatic tachycardia syndrome patients [PDF]

Korean Journal of Pediatrics, 2013
PurposeChronic day-to-day symptoms of orthostatic intolerance are the most notable features of postural orthostatic tachycardia syndrome (POTS). However, we have encountered patients with such symptoms and excessive tachycardia but with no symptoms ...

Optical Gravitational Wave Antenna with Increased Power Handling Capability [PDF]

, 2015
Fundamental sensitivity of an optical interferometric gravitational wave detector increases with increase of the optical power which, in turn, limited because of the opto-mechanical parametric instabilities of the interferometer.

Improved constraints on non-Newtonian forces at 10 microns

, 2008
Several recent theories suggest that light moduli or particles in "large" extra dimensions could mediate macroscopic forces exceeding gravitational strength at length scales below a millimeter.

Benefit of dual-chamber pacing with Closed Loop Stimulation in tilt-induced cardio-inhibitory reflex syncope (BIOSync trial): study protocol for a randomized controlled trial

Trials, 2017
Background The efficacy of dual-chamber cardiac pacing in neuro-mediated reflex syncope with a cardio-inhibitory response to the Tilt-Table test (TT) has not been definitively assessed so far.
