The structural composition and the properties of the first quantum spin-orientation–dependent correction to synchrotron radiation power are discussed. On the basis of spin mass renormalization it is shown that, in the conventional sense, the Thomas precession is not a source of relativistic radiation. This conclusion is in agreement with well-known statements on the spin dependence of mass and ...

We discuss recent developments in macroscopic-microscopic mass models, including the 1992 finite-range droplet model, the 1992 extended-ThomasFermi Strutinsky-integral model, and the 1994 Thomas-Fermi model, with particular emphasis on how well they extrapolate to new regions of nuclei. We also address what recent developments in macroscopic-microscopic mass models are teaching us about such ph...

We investigate the particle and kinetic energy densities of harmonically trapped fermion gases at zero temperature in arbitrary dimensions. We derive analytically a differential equation connecting these densities, which so far have been proven only in one or two dimensions, and give other interesting relations involving several densities or the particle density alone. We show that in the asymp...

After an introduction to the basics on Petri nets (PNs), I present a brief overview of their use for the modelling of biological networks, in particular for the qualitative modelling of metabolic networks by means of standard PNs. At a higher level of abstraction, the genetic regulatory networks are qualitatively modelled using the logical approach initially introduced by R. Thomas. I summarise...

A Combined Retail Evolution model was developed for this study in fulfillment of Objectives 1 and 2. The Combined Retail Evolution model was developed from previous retail evolution theories (i.e., the conceptual and empirical literature reviewed in Chapter II), which provided detailed information about retail change and fragmented information about consumer change. No single retail evolution t...

In Table 2 we have collected results for o for certain elements belonging to the same groups in the periodic table. Table 2 contains the numerical values of the total cross section for several elements. The results show that o is not a monotonic function of k for small A:-values but neither a complicated function of k. o contains some maxima and minima which means it ahs an oscillatory characte...

The calculation of the electronic energy levels of n-type d-doped quantum wells in a AlGaAs matrix is presented. Many-body effects in the two-dimensional electron gas are taken into account by using a local-density Thomas-Fermi approach. Special consideration is taken into when the values of the Al molar fraction xR0.45, and the ternary alloy becomes an indirect gap material. The results sugges...

Proactive interference (PI) refers to the finding that memory for recently studied (target) information can be vastly impaired by the previous study of other (nontarget) information. PI can be reduced in a number of ways, for instance, by directed forgetting of the prior nontarget information, the testing of the prior nontarget information, or an internal context change before study of the targ...

The l a method for an atom or molecule is transformed into an all-electron pseudopotential formalism. The equations of the l a method are exactly transformed into pseudo-orbital equations and the resulting pseudopotentials are replaced by simple density-dependent potentials derived from Thomas-Fermi model. It is shown that the new formalism satisfies the virial theorem. As the first application...

The effects of spatial correlations of density fluctuations on merger histories of dark matter haloes (so-called ‘merger trees’) are analysed. We compare the mass functions of dark haloes derived by a new method for calculating merger trees, that proposed by Rodrigues & Thomas (RT), with those given by other methods such as the Block model, the Press-Schechter formula and our own formula in whi...
