A procedure with a Bayesan approach for calculating upper limits to gravitational wave bursts from coincidence experiments with multiple detectors is described.

A recent letter reports an upper limit on the galactic compact binary inspiral rate set by gravitational wave observations using the LIGO 40M prototype interferometer. The limit was set by imagining a threshold set equal to the amplitude of the loudest event and then considering the probability that only one event was observed with amplitude greater than the threshold. That limit can be improve...

If a source is not detected above some flux threshold (when expected to be present at a target position), how can one assign a plausible upper limit to its flux such that (i) it has precise probabilistic meaning; (ii) has a degree of confidence that is not subjective or arbitrarily conservative; and (iii) has no dependence on any prior knowledge about the flux? Unfortunately, the astronomical l...

Context. Very high magnetic fields at the surface of neutron stars or in the accretion disk of black holes inhibit the production of jets. Aims. We quantify here the magnetic field strength for the jet formation. Methods. By using, the Alfvén Radius, RA, we study what we call the basic condition, RA/R∗ = 1 or RA/RLSO = 1 (LSO, last stable orbit), in its dependency with the magnetic field streng...

IMPORTANCE Central neck dissection (CND) is considered an imperative part of the treatment of patients with high-risk, well-differentiated thyroid carcinoma. OBJECTIVE To examine the presence of lymphatic tissue and/or metastatic nodes in the upper part of the paratracheal region to determine the need to dissect this region as part of a paratracheal neck dissection. DESIGN, SETTING, AND PAR...
