Let F be a finite group with a Sylow 2-subgroup S that is normal and abelian. Using hyperelementary induction and cartesian squares, we prove that Cappell’s unitary nilpotent groups UNil∗(Z[F ];Z[F ],Z[F ]) have an induced isomorphism to the quotient of UNil∗(Z[S];Z[S],Z[S]) by the action of the group F/S. In particular, any finite group F of odd order has the same UNil-groups as the trivial gr...

The Lennard-Jones (LJ) Potential Energy Problem is to construct the most stable form of N atoms of a molecule with the minimal LJ potential energy. This problem has a simple mathematical form

This paper argues that significant research and teaching in experimental phonetics at UCL preceded the establishment of the laboratory in 1912 by almost a decade. The forgotten work of E. R. Edwards [1] combined descriptive and experimental approaches in a pioneering study of Japanese. Recently recovered artefacts, and a close reading of the early publications of Daniel Jones (DJ), reveal a sur...

MOTIVATION Computational studies of the energetics of protein association are important for revealing the underlying fundamental principles and for designing better tools to model protein complexes. The interaction cutoff contribution to the ruggedness of protein-protein energy landscape is studied in terms of relative energy fluctuations for 1/r(n) potentials based on a simplistic model of a p...

The nature of Bence Jones proteins is developed by a review of the pertinent literature. This is followed by a discussion of their metabolism and catabolism under normal and abnormal clinical conditions. Various methods for the detection of Bence Jones proteins are critically reviewed and the significance of these pro­ teins in various disorders is assessed.

the virial coefficients can be obtained from statistical mechanics in connection with the intermolecular potentials. the intermolecular potential of polyatomic molecules is usually assumed to consist of a spherically symmetric component plus a contribution due to asphericaity of the molecular charge distribution. in this study, the second virial coefficients have been calculated for n2, co and ...

The microscopic effective pairing interaction in the S0-channel is investigated for two different values of the chemical potential μ starting from the separable form of the Paris NN-potential. It is shown that, within a high accuracy, this effective interaction can be approximated by the off-shell free T -matrix taken at the negative energy E = 2μ.
