Site-directed Mutagenesis of Cytochromec 6 from Synechocystissp. PCC 6803
(Elsevier, 1999)
This paper reports the first site-directed mutagenesis analysis of any cytochrome c 6, a heme protein that performs the same function as the copper-protein plastocyanin in the electron transport chain of photosynthetic ...

Origin of density clustering in a freely evolving granular gas
(American Physical Society, 1999)
The physical mechanisms leading to the development of density inhomogeneities in a freely evolving low density granular gas are investigated. By means of the direct simulation Monte Carlo method, numerical solutions of the ...

Excitation of multiple giant dipole resonances: From spherical to deformed nuclei
(Elsevier, 1999)
The effect of deformation on the excitation of multiple giant dipole resonances is studied. Analytical expressions are derived in the framework of the interacting boson model for the energies and E1 properties of giant ...

On the approximate and null controllability of the Navier-Stokes equations
(Society for Industrial and Applied Mathematics, 1999-06)
This paper presents some known results on the approximate and null controllability of the Navier–Stokes equations. All of them can be viewed as partial answers to a conjecture of J.-L. Lions.

Brownian motion in a granular gas
(American Physical Society, 1999)
The dynamics of a heavy particle in a gas of much lighter particles is studied via the Boltzmann-Lorentz equation with inelastic collisions among all particles. A formal expansion in the ratio of gas to tagged particle ...

Coupling the Stokes and Navier-Stokes equations with two scalar nonlinear parabolic equations
(EDP Sciences, 1999)
This work deals with a system of nonlinear parabolic equations arising in turbulence modelling. The unknowns are the N components of the velocity field u coupled with two scalar quantities θ and ϕ. The system presents ...

Quasielastic scattering from relativistic bound nucleons: Transverse-longitudinal response
(American Physical Society, 1999-12-27)
Predictions for electron induced proton knockout from p1/2 and p3/2 shells in 16O are presented using various approximations for the relativistic nucleonic current. Results for differential cross section, transverse-longitudinal ...

Logarithmic differential operators and logarithmic de Rham complexes relative to a free divisor
(Elsevier, 1999)
We prove a structure theorem for differential operators in the 0-th term of the V-filtration relative to a free divisor. manifold. As an application, we give a formula for the logarithmic de Rham complex with respect to a ...

Simulation study of the link between molecular association and reentrant miscibility for a mixture of molecules with directional interactions
(American Physical Society, 1999-06-28)
The reentrant liquid-liquid miscibility of a symmetrical mixture with highly directional bonding interactions is studied by Gibbs ensemble Monte Carlo simulation. The resulting closed loop of immiscibility and the corresponding ...
