The time-dependent role of cations was investigated by ageing four different aqueous solutions of cation chlorides. A linear correlation was found between the cations’ Setchenov coefficient for the salting-out of benzene and the increase in the conductivity with time. The conductivity of the structure-breaking cations or the chaotropes increased more significantly with time than the conductivit...

We reply to the Comment by Achim Rosch 1) who challenges our finding in Ref. 2) with regard to the validity of the Luttinger theorem in the cases of Mott insulating N-particle ground states (even) when the chemical potential used in applying this theorem coincides with the zero-temperature limit of the chemical potential satisfying the equation of state corresponding to N particles. Rosch furth...

Proposal This proposal describes the innovative and competitive lunar payload solution developed at the Queensland University of Technology (QUT) – the LunaRoo: a hopping robot designed to exploit the Moon's lower gravity to leap up to 20m above the surface. It is compact enough to fit within a 10cm cube, whilst providing unique observation and mission capabilities by creating imagery during th...

We investigate the excitation spectrum of a model of N colour fermions with correlated hopping which can be solved by a nested Bethe ansatz. The gapless excitations of particle-hole type are calculated as well as the spin-wave like excitations which have a gap. Using general predictions of conformal field theory the long distance behaviour of some groundstate correlation functions are derived f...

We develop a theory for the electronic excitations in UPt 3 which is based on the localization of two of the 5f electrons. The remaining f electron is delocalized and acquires a large effective mass by inducing intra-atomic excitations of the localized ones. The measured deHaas-vanAlphen frequencies of the heavy quasiparticles are explained as well as their anisotropic heavy mass. A model calcu...

A method is presented to determine the diversity gain achieved by increasing the hopping rate in a frequency hopped spread spectrum system using frequency mean square correlation (FMSC). In particular, it is demonstrated that the detailed shape of the delay power profile of a given channel does not play a fundamental role in the determination of the performance saturation point given the FMSC o...

Different from one-dimensional systems, nesting in two-dimensional (2D) systems is not perfect but some 2D systems still have Peierls instability and hidden nesting. This paper shows that the nextnearest neighbor (NNN) hopping which controls the nesting deviation, heavily suppresses the Peierls instability. There is a critical value for the NNN hopping, beyond which the Peierls instability is d...

that run on one leg. The generalization uf these one-leg algorithms for control of machines with several legs is explored. The generalization is quite simple when multilegged systems run with gaits that use the support legs one at a time. For these gaits the ~ n e-l e g algorithms can be used b o control multilegged running. The cortcept of a virtual leg is introduced to further extend the appr...

Diffusion-limited reaction A+A→inert with anisotropic hopping on the d = 1 lattice, is solved exactly for a simultaneous updating, discrete time-step dynamics. Diffusion-dominated processes slow down as the anisotropy increases. For large times or large anisotropy, one can invoke the appropriate continuum limits. In these limits the effects of the anisotropy on variation of particle density can...
