The variability of the large-amplitude internal wave field on the Australian North West Shelf
Internal waves Solitary waves Internal tide Continental slope Australian North West Shelf (14–221S, 114–1261E)
2015/6/30
Observations are presented of large-amplitude internal waves (LAIWs) generated by the steepening of the internal tide on the Australian North West Shelf (NWS) over a 4-month period extending from stro...
The leading chiral electromagnetic correction to the nonleptonic Delta I=3/2 amplitude in kaon decays
Kaon decay electromagnetic radiation amplitude phenomenology electromagnetic effect
2014/12/22
In kaon decay, electromagnetic radiative corrections can generate shifts in the apparent ΔI=3/2 amplitude of order αA0/A2not, vert, similar22α. In order to know the true ΔI=3/2 amplitude for compariso...
We propose amplitude death phenomenon as an underlying mechanism of auditory transduction. When non-identical auditory hair bundles are elastically coupled, their spontaneous oscillations can be quenc...

Explicit expressions of the vertex constant for the decay of a nucleus into two charged particles for an arbitrary orbital momentum $l$ are derived for the standard expansion of the effective-range fu...
Global existence of small amplitude solution to nonlinear system of wave and Klein-Gordon equations in four space-time dimensions
Global existence nonlinear system wave and Klein-Gordon equations four space-time dimensions
2011/9/14
Abstract: In this article one will develop a so-called hyperboloidal foliation method, which is an energy method based on a foliation of space-time into hyperboloidal hypersurfaces. This method permit...
Pulse-amplitude-resolved spectroscopy of bright accreting pulsars: indication of two accretion regimes
X-ray binaries – neutron stars – accretion
2011/10/8
Context: In addition to coherent pulsation, many accreting neutron stars exhibit flaring activity and strong aperiodic variability on time scales comparable to or shorter than their pulsation period. ...
