Experiments and theory characterize the novel chaotic neoclassical transport scaling as νcB in contrast to traditional collisional neoclassical transport scaling as ν 1/2 c B−1/2. This chaotic transport occurs when local trapping separatrices have θ-variations or temporal fluctuations. Experiments observe bulk particle transport, damping of Langmuir waves and diocotron waves, and nonlinear wave...

[1] We present a revised model of soil evolution constrained by the recent LSCC data for lunar soils. In addition to an observed universal increase in feldspathic components in the finer fractions of soils [Taylor et al., 2001, 2003a, 2003b], both differential melting and lateral mixing processes appear to be required during the evolution of lunar soils. We propose mare-highland mixing of a sig...

A review of the problem of neutrino mass, mixing and oscillations is given. Possible phenomenological schemes of neutrino mixing are discussed. The most important consequences of neutrino mixing–neutrino oscillations are considered in some details. The data of atmospheric, solar and LSND experiments are discussed. The results of phenomenological analyses of the data under the assumption of the ...

We describe an algorithm and chip implementation for separating a mixture of unknown, but independent, temporal signals in static and dynamic environments. The proposed algorithm, which is a simple modi cation of the Herault and Jutten (HJ) algorithm, proved to be robust to parameter variations in both cases. We present chip test results to quantify the performance of the modi ed algorithm in s...

In this paper, we exhibit, for any sparse enough increasing sequence {pn} of integers, totally minimal, totally uniquely ergodic, and topologically mixing systems (X,T ) and (X ′, T ′) and f ∈ C(X) for which the averages 1 N ∑N−1 n=0 f(T nx) fail to converge on a residual set in X , and where there exists x′ ∈ X ′ with x′ / ∈ {T ′pnx′}.

The portioning-mixing (PM) procedure is one of the earliest combinatorial synthetic methods. It was introduced 10 years ago, in 1988 [1]-[3]. This method exemplified the first time that it is possible to prepare with high confidence a previously unimaginable large number of compounds. It taught a large number of chemists to think combinatorially. The tenth anniversary of the method offers an oc...

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 non-supersymmetric grand unified models a “radiative fermion mass hierarchy” can be achieved in which the spectrum of quark and lepton masses is determined entirely by physics at the unification scale, with many relations following from the unified gauge symmetry, and with the masses of the lightest family arising from loops. A simple, realistic, and predictive model of this kind is presente...

We examine the constraints imposed by the requirement of successful nucleosynthesis on models with one large extra hidden space dimension and a single bulk neutrino residing in this dimension. We first use naive out of equilibrium conditions to constrain the size of the extra dimensions and the mixing between the active and the bulk neutrino. We then use the solution of the Boltzman kinetic equ...

If neutrinos are to play a relevant cosmological role, they must be essentially degenerate. We study whether radiative corrections can or cannot be responsible for the small mass splittings, in agreement with all the available experimental data. We perform an exhaustive exploration of the bimaximal mixing scenario, finding that (i) the vacuum oscillations solution to the solar neutrino problem ...
