Unprecedented study of the broadband emission of mrk 421 during flaring activity in march 2010
(EDP Sciences, 2015-05-27)
Context. Because of its proximity, Mrk 421 is one of the best sources on which to study the nature of BL Lac objects. Its proximity allows us to characterize its broadband spectral energy distribution (SED). Aims. The goal ...
The 2009 multiwavelength campaign on mrk 421: variability and correlation studies
(EDP Sciences, 2015-04-01)
Aims. We perform an extensive characterization of the broadband emission of Mrk 421, as well as its temporal evolution, during the non-flaring (low) state. The high brightness and nearby location (z = 0.031) of Mrk 421 ...
Multiwavelength observations of mrk 501 in 2008
(EDP Sciences, 2014-12-17)
Context. Blazars are variable sources on various timescales over a broad energy range spanning from radio to very high energy (&gt;100 GeV, hereafter VHE). Mrk 501 is one of the brightest blazars at TeV energies and ...
Multiwavelength observations of the previously unidentified blazar rx j0648.7+1516
(IOP Publishing, 2011-11-15)
We report on the VERITAS discovery of very high energy (VHE) gamma-ray emission above 200 GeV from the high-frequency-peaked BL Lac (HBL) object RX J0648.7+1516 (GB J0648+1516), associated with 1FGL J0648.8+1516. The photon ...
Detection of pulsed gamma rays above 100 gev from the crab pulsar
(American Association for the Advancement of Science (AAAS), 2011-10-06)
We report the detection of pulsed gamma rays from the Crab pulsar at energies above 100 giga-electron volts (GeV) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) array of atmospheric Cherenkov ...
Deep broadband observations of the distant gamma-ray blazar pks 1424+240
(IOP Publishing, 2014-03-28)
We present deep VERITAS observations of the blazar PKS 1424+240, along with contemporaneous Fermi Large Area Telescope, Swift X-ray Telescope, and Swift UV Optical Telescope data between 2009 February 19 and 2013 June 8. ...
Geohab–the global ecology and oceanography of harmful algal blooms program: motivation, goals, and legacy
(The Oceanography Society, 2017-03-01)
In 2001, the first international research program focusing exclusively on harmful marine algae, GEOHAB (Global Ecology and Oceanography of Harmful Algal Blooms), was established by the HAB research community, under the ...

Intra-abdominal hypertension and the abdominal compartment syndrome: updated consensus definitions and clinical practice guidelines from the world society of the abdominal compartment syndrome
(Springer Nature, 2013-05-15)
To update the World Society of the Abdominal Compartment Syndrome (WSACS) consensus definitions and management statements relating to intra-abdominal hypertension (IAH) and the abdominal compartment syndrome (ACS). We ...
Hydroxymethylglutaryl-coa reductase inhibition with simvastatin in acute lung injury to reduce pulmonary dysfunction (harp-2) trial: study protocol for a randomized controlled trial
(Springer Nature, 2012-09-17)
Background: Acute lung injury (ALI) is a common devastating clinical syndrome characterized by life-threatening respiratory failure requiring mechanical ventilation and multiple organ failure. There are in vitro, animal ...
