A thought experiment considering conservation of energy and momentum for a pair of free bodies together with their internal energy is used to show the existence of states that have localised position while being eigenstates of energy and momentum. These states are applicable to all varieties of physical bodies, including planets and stars in free motion in the universe. The states are compound ...

Abstract The approximation of steady-state vibrations within non-linear dynamical systems is well-established in academics and becoming increasingly important industry. However, the complexity number degrees freedom application-oriented industrial models demand efficient methods for solutions. One possible approach to that problem are hybrid schemes, which combine advantages standard from liter...

Recent work on the behaviour of localised states in pattern forming partial differential equations has focused on the traditional model Swift-Hohenberg equation which, as a result of its simplicity, has additional structure — it is variational in time and conservative in space. In this paper we investigate an extended Swift-Hohenberg equation in which non-variational and non-conservative effect...

Hypohidrotic ectodermal dysplasia has been mapped to Xq11-q13 by linkage studies and by a translocation in a manifesting female. We report a family with hypohidrotic ectodermal dysplasia in which the disease did not segregate with this region of the X chromosome as expected. Ten DNA probes which are localised between Xp11 and Xq22 were used in the investigation. The difficulties in diagnosing t...

We report muon spin relaxation and inelastic neutron measurements on the Heusler system YbPd2Sn. Localised anisotropic and quasi-elastic Yb magnetic fluctuations are observed below T = 150K. Both μSR and neutron data indicate a slowing-down of the spin-fluctuations, upon lowering the temperature, similar to that observed in Kondo lattices. The temperature dependence of the quasi-elastic neutron...
