Double Crossproducts of Hopf* Algebras, Discrete Quantum Groups and Amenable Groups
In Appendix A, we consider a third construction, the bicrossproduct which is a simultaneous cross product/cross coproduct construction. We find conditions which ensure that the bicrossproduct of two Hopf $\sp{\*}$ algebras is a Hopf $\sp{\*}$ algebra. In Appendix B, we provide physical motivation …

Nonlinear Growth of Structure in Cosmological Simulations
Finally, we present the results of a comparison between 10 different cosmology codes. These include virtually all major codes used today, and more importantly, they completely cover the range of numerical algorithms used in cosmological N-body simulations. For the mass function, the matter power …

Physics of Compton Scattering and X-Ray Spectra of Weakly Magnetic Accreting Neutron Stars
… with spherical symmetry. The algorithm is a generalization of the method of Eddington factors and provides solutions that are valid both in the diffusion and free-streaming regimes. Using this algorithm we perform detailed numerical calculations of the X-ray spectra of the so-called Z sources …

Theoretical Studies of Quantum Dynamics
Using the FPF method, we have carried out accurate path integral simulations of the primary charge separation in bacterial photosynthesis. The process is modeled in terms of three coupled electronic states corresponding to the photoexcited special pair, the reduced accessory bacteriochlorophyll and …

Quantum Electrodynamic Theory of Optical High-Order Harmonic Generation
Based on the theoretical analysis, harmonies with higher orders are predicted to be generated with higher efficiency, if a means is devised to utilize more energetic photoelectrons to the harmonic generation process.

Experimental Evidence for Mixed Reality States in an Interreality System, And, Generalized Resonant Forcing of Nonlinear Dynamics
… includes time-discrete chaotic maps as well as generalized systems of nonlinear first order differential equations. The calculus of variations is used to determine the minimal additive forcing function that induces a desired terminal response. In contrast to previous efforts, in this work only …

A Measurement of the Three-Body Photodisintegration of (3)He Between 81 and 157 MeV
Future comparison of the data with theory is possible via routines that allow theoretical calculations to be put into an identical format to the measured data.

A Numerical Study of Three-Dimensional Black Hole Spacetimes
We present results from numerical evolutions of vacuum black hole spacetimes in 3D Cartesian coordinates. We first studied the Schwarzschild spacetime, comparing extensively with 1D studies. We show that although accurate 3D evolutions are possible, there are a number of difficulties in evolving 3D …

Control of Ligand Binding to Heme Proteins: The Role of The Distal Histidine
We have investigated the effect of the distal histidine on the recombination rates of CO and O(,2) to sperm whale myoglobin, separated beta chains of normal human hemoglobin and to the beta chains of hemoglobin Zurich. The recombination was measured using flash photolysis from 300 to 40 K, on a …

Measured Electron Spin Relaxation Rates in Frozen Solutions of Azurin, Vitamin-B12r, and Nitrosyl Ferrous Myoglobin
Rates in frozen glycerin/water solutions at temperatures between 1.4 K and 20 K are reported for a copper-containing protein, azurin, and a cobalt-containing biomolecular complex, vitamin B$\sb{\rm 12r}$, the paramagnetic product of the photolysis of coenzyme B$\sb $. Results are interpreted in …

An X Ray Study of the Structure of Potassium(1-X)-Rubidium(x)-Carbon(y)
The mixed layered compounds K$\sb{\rm 1-x}$Rb$\sb{\rm x}$C$\sb8$ and K$\sb{\rm 1-x}$Rb$\sb{\rm x}$C$\sb{24}$ represent quasi two-dimensional alloys interleaved by graphite hexagonal planes. We report extensive x-ray scattering investigations of the structural aspects of these compounds.
