A Fractal Valued Random Iteration Algorithm and Fractal Hierarchy
Michael Barnsley, John E. Hutchinson, Örjan Stenflo
We describe new families of random fractals, referred to as "V-variable", which are intermediate between the notions of deterministic and of standard random fractals. The parameter…
Dark Matter Constituents
Lars Bergstrom
As cosmology has entered a phase of precision experiments, the content of the universe has been established to contain interesting and not yet fully understood components, namely d…
Q-LET - Quick Lensing Estimation Tool - An application to SN2003es
Christofer Gunnarsson
Q-LET is a FORTRAN 77 code that enables a quick estimate of the gravitational lensing effects on a point- or an extended source. The user provided input consists of the redshifts,…
A measurement of the branching fractions of the b-quark into charged and neutral b-hadrons
The DELPHI Collaboration, J. Abdallah
The production fractions of charged and neutral b-hadrons in b-quark events from Z0 decays have been measured with the DELPHI detector at LEP. An algorithm has been developed, base…
Hamiltonian structure and noncommutativity in -brane models with exotic supersymmetry
D. V. Uvarov, A. A. Zheltukhin
The Hamiltonian of the simplest super -brane model preserving 3/4 of the D=4 N=1 supersymmetry in the centrally extended symplectic superspace is derived and its symmetries are…
Three charged particles in the continuum. Astrophysical examples
V. B. Belyaev, S. B. Levin, S. L. Yakovlev
We suggest a new adiabatic approach for description of three charged particles in the continuum. This approach is based on the Coulomb-Fourier transformation (CFT) of three body Ha…
