On the Marriage of Chiral Perturbation Theory and Dispersion Relations
Dispersion relations chiral perturbation theory gw PI
2014/12/23
I describe the methodology for the use of dispersion relations in connection with chiral perturbation theory. The conditions for matching the two formalisms are given at $O(E^2)$ and $O(E^4)$. The two...
The techniques of dispersion relations match very well with those of effective field theory. I describe the techniques for using dispersion relations effectively, and give some pedagogical examples to...
Applicability of an integrated plume rise model for the dispersion from wild-land fires
rise model wild-land fires
2014/12/19
We have presented an overview of a mathematical model, BUOYANT, that was originally designed for the evaluation of the dispersion of buoyant plumes originated from major warehouse fires. The model add...
The Lagrangian particle dispersion model FLEXPART-WRF version 3.1
model FLEXPART-WRF Lagrangian particle dispersion
2014/12/12
The Lagrangian particle dispersion model FLEXPART was originally designed for calculating longrange and
mesoscale dispersion of air pollutants from point sources.
Crustal velocity structure of the Deccan Volcanic Province, Indian Peninsula, from observed surface wave dispersion
Deccan Volcanic Province Surface waves Crustal structure
2015/8/18
Through inversion of fundamental mode group velocities of Love and Rayleigh waves, we study the crustal and subcrustal structure across the central Deccan Volcanic Province (DVP), which is one of the ...
Dispersion of swimming algae in laminar and turbulent channel flows: theory and simulations
algae swimming microorganisms Taylor dispersion DNS turbulent transport bioreactors
2012/5/31
Algal swimming is often biased by environmental cues, e.g. gravitational and viscous torques drive cells towards downwelling fluid (gyrotaxis). In view of biotechnological applications, it is importan...
Controllable steep dispersion with gain in a four-level N-scheme with four-wave mixing
Controllable steep dispersion gain four-level N-scheme four-wave mixing Atomic Physics
2012/5/31
We present a theoretical analysis of the propagation of light pulses through a medium of four-level atoms, with two strong pump fields and a weak signal field in an N-scheme arrangement. We show that ...
Dispersion of artificial caesium-134 and -137 in the western North Pacific one month after the Fukushima accident
Fukushima caesium western North Pacific zooplankton suspended solids
2017/4/11
In March 2011, an accident at the Fukushima Daiichi nuclear power plant (FNPP-AC) was caused by the Tohoku
earthquake and tsunami. Here we show the distribution of artificial caesium-134 and -137 (13...
Monitoring and Dispersion Modeling of Polybrominated Diphenyl Ethers (PBDEs) in the Ambient Air of Two Municipal Solid Waste Incinerators and a Coal-fired Power Plant
Polybrominated diphenyl ethers (PBDEs) Municipal solid waste incinerators Coal-fired power plant Stack flue gases Dispersion
2016/3/28
The concentration of polybrominated diphenyl ethers (PBDEs) in the ambient air of two municipal solid waste
incinerators (MSWIs) and one coal-fired power plant (TPP) were determined. Along with the s...
The intrinsic dispersion of the Faber-Jackson relation for early-type galaxies as function of the mass and redshift
Galaxies fundamental parameters photometry distances redshifts
2011/10/18
Aims. Recently it has been reported that the intrinsic dispersion at constant magnitude of the structural relations from early-type galaxies is a useful tool to study the universality of these structu...

2011/8/18
Abstract: Experimental results for passive tracer dispersion in the turbulent surface layer under stable conditions are presented. In this case, the dispersion of tracer particles is determined by the...
