The diffusion tensor and velocity correlation function of a Brownian particle immersed in a viscous compressible fluid confined between two parallel plane walls are calculated in point approximation. The fluid is assumed to satisfy stick boundary conditions at the walls. It is found that the velocity correlation function decays asymptotically with a negative t(-2) long-time tail due to coupling...

By use of Green 's functions f o r the diffusional motion a very concise formulation and computation of correlation functions is possible. For an axially symmetric overall diffusion with internal rotation about one and two axes correlation functions of a second rank spherical tensor are calculated. The results comprise all the solutions of the pertinent problem as given so far and allow the ext...

The two-point correlation function of the stress-energy tensor for the Φ 1,3 massive deformation of the non-unitary model M 3,5 is computed. We compare the ultraviolet CFT perturbative expansion of this correlation function with its spectral representation given by a summation over matrix elements of the intermediate asymptotic massive particles. The fast rate of convergence of both approaches ...

A factorized and analytical form for the A(γ,pp) and A(e,epp) cross section is proposed. In the suggested scheme the two-proton knockout cross sections can be directly analyzed in terms of the ground-state correlation functions. Central, spin-spin and tensor correlations are considered. In the longitudinal channel, the (e,epp) cross section is predicted to exhibit a peculiar sensitivity to grou...

∗ Author for correspondence. Abstract: In this paper we have analysed the aperiodic correlation properties and the average BER performance of a family of complex orthogonal sequences suitable for code spreading in an asynchronous BPSK DS-CDMA communication system. The proposed complex sequences form a complex orthogonal matrix with desirable equal odd and even aperiodic correlations. Concatenat...
