(University College Dublin. School Of Economics, 2006-11)We extend the Bikhchandani, Hirshleifer and Welch (1992) informational cascade framework to allow for asymmetric signal accuracy. Simulations demonstrate that even small departures from symmetry may lead to non-monotonic ...

(Optical Society of America, 2009-10-11)If we sample a scalar wave field, it becomes periodic in frequency. We examine the cross-terms which occur between these periodic replicas in the Wigner-Ville distribution function of such a signal. We present analytic ...

(Institution of Civil Engineers/Thomas Telford Publishing, 2012-03-01)Accurate determination of shear wave arrival time using bender elements may be severely affected by a combination of near field effects and reflected waves. These may mask the first arrival of the shear wave, making its ...

(Elsevier, 2008-08)In humans, thromboxane (TX) A2 signals through the TPalpha and TPbeta isoforms of the TXA2 receptor that exhibit common and distinct roles. For example, Gq/phospholipase (PL)Cbeta signaling by TPalpha is directly inhibited ...

(Optical Society of America, 2011-07-10)Modeling the propagation of light through free space and simple paraxial systems continue to be enduring, and practically important topics in optics. Is there anything new or interesting that remains to be said? Given the ...

(Institute of Electrical and Electronic Engineers, 2012-05)This article gives a brief description of the Degenerate Unmixing Estimation Technique (DUET) and applies it in a geophysical setting. Source separation has not been fully addressed by geophysicists and is a crucial first ...

(Optical Society of America, 2008-02-01)A signal may have compact support, be band-limited (i.e., its Fourier transform has compact support), or neither (“unbounded”). We determine conditions for the linear canonical transform of a signal having these properties. ...

(Portland Press, 2001)Since its discovery in 1975, we now have a wealth of knowledge relating to the biochemical, pharmacological and physiologic actions of thromboxane (TX) A2 and its related metabolites. These molecular insights have been ...

(Springer-Verlag, 2013-01)Tumour necrosis factor (TNF)-α is a pro-inflammatory cytokine, which is synthesised and released in the brain by astrocytes, microglia and neurons in response to numerous internal and external stimuli. It is involved in ...

(IEEE, 2007-11)An important pre-processing stage in speech recognition systems is that of extracting phonetically pertinent acoustic features from the speech signal. These features form the basis for discriminative classification and ...
