The distribution of pairwise peculiar velocities in the nonlinear regime [PDF]

open access: yes, 1995
The distribution of pairwise, relative peculiar velocities, $f(u;r)$, on small nonlinear scales, $r$, is derived from the Press--Schechter approach. This derivation assumes that Press--Schechter clumps are virialized and isothermal.

Analytical Non-Decoupled Solution and Dispersion Characteristics of Rayleigh Waves in Multi-Layered Vertical Transverse Isotropic Media

open access: yesMathematics
Seismic wavefield simulation is the primary technique used to study the effects of vertical transverse isotropy (VTI) on the propagation of Rayleigh waves.

Steeping and dispersive effects analysis of a couple of long-wave equations in dispersive media

open access: yesAlexandria Engineering Journal, 2022
Dispersive wave propagations are described by nonlinear models, such as regularized long waves and modified regularized long waves, where nonlinearity and dispersion are important aspects of wave evolution to model long-wave propagation in dispersive ...

Equilibrium Disk-Bulge-Halo Models for the Milky Way and Andromeda Galaxies

open access: yes, 2005
We describe a new set of self-consistent, equilibrium disk galaxy models that incorporate an exponential disk, a Hernquist model bulge, an NFW halo and a central supermassive black hole.

Towards a unique formula for neutrino oscillations in vacuum [PDF]

open access: yes, 2002
We show that all correct results obtained by applying quantum field theory to neutrino oscillations can be understood in terms of a single oscillation formula.

Taylor Approximations for Model Uncertainty within the Tweedie Exponential Dispersion Family [PDF]

open access: yesASTIN Bulletin, 2009
AbstractThe use of generalized linear models (GLM) to estimate claims reserves has become a standard method in insurance. Most frequently, the exponential dispersion family (EDF) is used; see e.g. England, Verrall. We study the so-called Tweedie EDF and test the sensitivity of the claims reserves and their mean square error of predictions (MSEP) over ...

Conservation Laws, Soliton Dynamics, and Stability in a Nonlinear Schrödinger Equation with Second-Order Spatiotemporal Dispersion

open access: yesMathematics
This paper presents the construction of exact wave solutions for the generalized nonlinear Schrödinger equation (NLSE) with second-order spatiotemporal dispersion using the modified exponential rational function method (mERFM).

Pulsar motions in our Galaxy

open access: yes, 2004
Pulsar motions in our Galaxy from their birth until 2 Gyr are studied statistically via Monte-Carlo simulation of $2\times 10^5$ pulsars with the best available representation of the Galactic potential.

Constrained Violent Relaxation to a Spherical Halo [PDF]

open access: yes, 1999
Violent relaxation during the collapse of a galaxy halo is known to be incomplete in realistic cases such as cosmological infall or mergers. We adopt a physical picture of strong but short lived interactions between potential fluctuations and particle ...

The COM-Poisson Process for Stochastic Modeling of Osmotic Inactivation Dynamics of Listeria monocytogenes

open access: yesFrontiers in Microbiology, 2021
Controlling harmful microorganisms, such as Listeria monocytogenes, can require reliable inactivation steps, including those providing conditions (e.g., using high salt content) in which the pathogen could be progressively inactivated.
