A measurement of gravitational wave (GW) propagation speed is one of important tests of gravity in a dynamical regime. We report a method to measure the GW propagation speed by directly comparing arrival times of GWs, neutrinos from supernovae (SN), and photons from short gamma-ray bursts (SGRB). We found that the future multimessenger observations can test the GW propagation speed with the pre...
Statistical veto methods are commonly used to reduce the list of candidate gravitational wave (GW) events which are detected as transient (burst) signals in the main output of GW detectors. If a burst event in the GW channel is coincident with an event in a veto channel (where the veto channel does not contain any GW signal), it is possible to veto the event from the GW channel with a low ‘fals...
Among the various schemes being considered for structural health monitoring (SHM), guided wave (GW) testing in particular has shown great promise. While GW testing using hand-held transducers for non-destructive evaluation (NDE) is a well established technology, GW testing for SHM using surface-bonded/embedded piezoelectric wafer transducers (piezos) is relatively in its formative years. Little...
The observation of the electromagnetic counterpart of gravitational-wave (GW) transient GW170817 demonstrated the potential in extracting astrophysical information from multimessenger discoveries. The forthcoming deployment of the first telescopes of the Cherenkov Telescope Array (CTA) observatory will coincide with Advanced LIGO/Virgo’s next observing run, O3, enabling the monitoring of gamma-...
In 2011, the Virgo gravitational wave (GW) detector will definitively end its science program following the shut-down of the LIGO detectors the year before. The years to come will be devoted to the development and installation of second generation detectors. It is the opportune time to review what has been learned from the GW searches in the kilometric interferometers data. Since 2007, data hav...
During the Laser Interferometer Gravitational-wave Observatory and Virgo joint science runs in 2009–2010, gravitational wave (GW) data from three interferometer detectors were analyzed within minutes to select GW candidate events and infer their apparent sky positions. Target coordinates were transmitted to several telescopes for follow-up observations aimed at the detection of an associated op...
Factor and multiple regression analysis were used to extract the morphometric variables that contributed to feeding success in three small freshwater fishes. Of the first two factors, factor 1, showed high loading of gut weight (GW), length of the upper (UJ), and lower jaws (LJ) in mola, Amblypharyngodon mola (Hamilton), and GW and vertical mouth opening (VMO) in punti, Puntius ticto (Hamilton)...
BACKGROUND Following the 1991 Gulf War (GW) there was much controversy surrounding service-related health effects. Evidence from the Vietnam experience suggested that self-reported ill health following that conflict might be related to how service during the conflict is framed. The aim of this article is to determine if a GW health effect persisted when the same questions were asked in a "non-G...
