Relationship between Aeolian tone and Wake Vortex from Inclined Flat Blade
Journal of Fluid Science and Technology, 2009 The three dimensional structure of the wake vortex was investigated in relating to the aeolian tone from the inclined blade. It was pointed out that the aeolian tone is largest not at zero, but at ten degree of the inclined angle.

Baryonic Signatures in Large-Scale Structure [PDF]
, 1998 We investigate the consequences of a non-negligible baryon fraction for models of structure formation in Cold Dark Matter dominated cosmologies, emphasizing in particular the existence of oscillations in the present-day matter power spectrum.

Responses in large-scale structure [PDF]
Journal of Cosmology and Astroparticle Physics, 2017 We introduce a rigorous definition of general power-spectrum responses as resummed vertices with two hard and $n$ soft momenta in cosmological perturbation theory. These responses measure the impact of long-wavelength perturbations on the local small-scale power spectrum.

Modified Newtonian Dynamics of Large Scale Structure [PDF]
, 2001 We examine the implications of Modified Newtonian Dynamics (MOND) on the large scale structure in a Friedmann-Robertson-Walker universe. We employ a ``Jeans swindle'' to write a MOND-type relationship between the fluctuations in the density and the ...

Large Scale Structure and Cosmic Rays revisited [PDF]
, 2000 We investigate the possibility that ultra high energy cosmic rays (E > 10^19 eV) are related to the distribution of matter on large scales. The large scale structure (LSS) data stems from the recent IRAS PSCz redshift survey.

The large-scale structure of homogeneous turbulence [PDF]
, 1967 A field of homogeneous turbulence generated at an initial instant by a distribution of random impulsive forces is considered. The statistical properties of the forces are assumed to be such that the integral moments of the cumulants of the force system ...
