Very High Energy Observations of Gamma-Ray Burst Locations with the Whipple Telescope
(2007)Gamma-ray burst (GRB) observations at very high energies (VHE, E > 100 GeV) can impose tight constraints on some GRB emission models. Many GRB afterglow models predict a VHE component similar to that seen in blazars and ... -

The Vibrio parahaemolyticus ToxRS Regulator Is Required for Stress Tolerance and Colonization in a Novel Orogastric Streptomycin-Induced Adult Murine Model
(American Society for Microbiology, 2012-03)Vibrio parahaemolyticus, a marine bacterium, is the causative agent of gastroenteritis associated with the consumption of seafood. It contains a homologue of the toxRS operon that in V. cholerae is the key regulator of ... -
The Vibrio parahaemolyticus Type III Secretion Systems manipulate host cell MAPK for critical steps in pathogenesis
(BioMed Central, 2011)Background:Vibrio parahaemolyticus is a food-borne pathogen causing inflammation of the gastrointestinal epithelium. Pathogenic strains of this bacterium possess two Type III Secretion Systems (TTSS) that deliver effector ... -
The Virasoro Algebra and Some Exceptional Lie and Finite Groups
(2006)We describe a number of relationships between properties of the vacuum Verma module of a Virasoro algebra and the automorphism group of certain vertex operator algebras. These groups include the Deligne exceptional series ... -
Virasoro Correlation Functions for Vertex Operator Algebras
(2011)We consider all genus zero and genus one correlation functions for the Virasoro vacuum descendants of a vertex operator algebra. These are described in terms of explicit generating functions that can be combinatorially ... -
The virulence plasmid of Yersinia, an anti-host genome
(American Society for Microbiology, 1998-12)Invasive pathogenic bacteria have in common the capacity to overcome the defense mechanisms of their animal host and to proliferate in its tissues. They each have their own life-style and target organs and cause a variety ... -
VLT / Infrared Integral Field Spectrometer Observations of Molecular Hydrogen Lines in the Knots in the Planetary Nebula NGC 7293 (the Helix Nebula)
(2007)Knots are commonly found in nearby planetary nebulae (PNe) and star forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and understanding the physics involved in knots ... -
VLT polarimetry observations of the middle-aged pulsar PSR B0656+14
(EDP Sciences, 2015-11-02)Context. Optical polarisation measurements are key tests for different models of the pulsar magnetosphere. Furthermore, comparing the relative orientation of the phase-averaged linear polarisation direction and the pulsar ... -
Volcanic sulphate and arctic dust plumes over the North Atlantic Ocean
(Elsevier, 2009)High time resolution aerosol mass spectrometry measurements were conducted during a field campaign at Mace Head Research Station, Ireland, in June 2007. Observations on one particular day of the campaign clearly indicated ... -
Volcanic texture identification and influence on permeability using a borehole resistivity image log in the Whakamaru Group Ignimbrite, Wairakei Geothermal Field, New Zealand
(Workshop on Geothermal Reservoir Engineering, 2018-02-12)Discerning the contributions to fluid flow in a geothermal reservoir from intrinsic and structural permeability components is an important, yet difficult task. High-quality, resistivity borehole image log data (Formation ... -
A wave near the edge of a circular disk
(2008)It is shown that in the Love-Kirchhoff plate theory, an edge wave can travel in a circular thin disk made of an isotropic elastic material. This disk edge wave turns out to be faster than the classic flexural acoustic wave ... -
Waves and vibrations in a solid of second grade
(World Scientific, 2006)We study the viscoelastic second grade solid, for which the constitutive equation consists in the sum of a purely elastic part and a viscoelastic part; this latter part is specified by two microstructural coefficients ... -
A Weibull-count approach for handling under- and overdispersed longitudinal/clustered data structures
(SAGE Publications, 2018-07-30)A Weibull-model-based approach is examined to handle under- and overdispersed discrete data in a hierarchical framework. This methodology was first introduced by Nakagawa and Osaki (1975, IEEE Transactions on Reliability, ... -
Weierstrass's criterion and compact solitary waves
(American Physical Society, 2007-04-17)Weierstrass's theory is a standard qualitative tool for single degree of freedom equations, used in classical mechanics and in many textbooks. In this Brief Report we show how a simple generalization of this tool makes it ... -
The weighted fusion category algebra and the $q$-Schur algebra for $\rm GL_2(q)$

What controls the magnetic interaction in bis-mu-alkoxo Mn(III) dimers? A combined experimental and theoretical exploration.
(Wiley, 2012-03-29)The synthesis and magnetic characterisation of a series of bis-mu-alkoxide bridged MnIII dinuclear complexes of general formula [MnIII2(mu-OR)2(biphen)2(ROH)x(L)y] (where R=Me, Et; H2biphen=2,2'-biphenol and L=terminally ... -
Whitecaps and the marine atmosphere, report no. 3
(1981-04)This report covers the period from 1 July, 1980 to 31 March, 1981, and is devoted to a description of the work carried out, and the results obtained, during this interval on the on-going ONR-sponsored study of "The Influence ... -
Whitecaps and the marine atmosphere, report no. 5
(1983-06)During this year we have continued making measurements of aerosols and electrostatic charge from our coastal tower in Gort na gCapall on Inishmore. Likewise, the experiments centred on the Whitecap Simulation Tank are ... -
Whitecaps and the marine atmosphere, report no. 6
(1984-06)This study is concerned with the interdependence of 10m elevation wind speed, oceanic whitecap coverage and marine aerosol concentration. The field work is divided into two distinct phases. On Inishmore Co. Galway. ...
