It is shown that the Coulomb energy U of fully ionized ionic mixture can be written as a sum over partial contributions of ion species j: U = T ∑ j Nju(Γj , yj) (generalized linear mixing rule). In contrast to the traditional linear mixing rule ULM = T ∑ j NjuOCP(Γj), applicable for strong coupling, the partial contribution function u depends not only on Γj , but on an additional parameter yj =...

The aim of microfluidic mixing is to achieve a thorough and rapid mixing of multiple samples in microscale devices. In such devices, sample mixing is essentially achieved by enhancing the diffusion effect between the different species flows. Broadly speaking, microfluidic mixing schemes can be categorized as either "active", where an external energy force is applied to perturb the sample specie...

In this paper we investigate mixing and transport in correspondence of a meandering jet. The large-scale flow field is a kinematically assigned streamfunction. Two basic mixing mechanisms are considered, first separately and then combined together: deterministic chaotic advection, induced by a time dependence of the flow, and turbulent diffusion, described by means of a stochastic model for par...

The PMNS neutrino mixing matrix UPMNS is in general a product of two unitary matrices Ulep and Uν arising from the diagonalization of the charged lepton and neutrino mass matrices, UPMNS = U † lepUν . Assuming that Uν is a bimaximal mixing matrix, we investigate the possible forms of Ulep. We identify three possible generic structures of Ulep, which are compatible with the existing data on neut...

Combining the FH entropy of mixing and the standard RS enthalpy of mixing yields the FH solution theory for polymers: ∆G N = Bφ1φ2 + RT (φ1 lnφ1 + φ2 N lnφ2). As written above, this equation is comparable to the free energy of mixing from the Regular Solution Model. Notice that the expressions differ in two ways: first, FH is cast in volume fractions rather than mole fractions, and second, FH i...

We discuss the process e ? e ? ! W ? W ? mediatedby heavy Majorana neutrino exchange in the t-and u channel. In our model the cross section for this reaction is a function of the masses (m N) of the heavy Majorana neutrinos and mixing parameters (U eN) originating from mixing between the ordinary left-handed standard model neutrinos and additional singlet right-handed neutrino elds. Taking into...

Some low-energy manifestations of a minimal extension of the Standard Model based on the quark-lepton SU (4) V ⊗ SU (2) L ⊗ G R symmetry of the Pati-Salam type are analysed. Given this symmetry a new type of mixing in the quark-lepton interactions is shown to be required. An additional arbitrariness of the mixing parameters could allow to decrease noticeably the lower bound on the leptoquark ma...

In homonuclear molecules, such as H2, the rovibrational levels close to the dissociation threshold do not have definite symmetry with respect to the inversion of electronic variables. This effect—the gerade–ungerade mixing—results from interactions between magnetic moments of electrons and protons. We calculate this mixing on the level of adiabatic approximation and numerically solve the system...
