The deenition of a class C of functions is predicative if it doesn't use a class containing C; and is decidable if membershipto C can be decided syntactically, from the construction of its elements. Decidable and predicative characterizations of Poly-time functions are known. We present here such a characterization for the following classes of languages: P, p n ; p n , PH and PSPACE. It is obta...

Tacrine (THA) and physostigmine (PHS) have been used in Alzheimer's disease therapy for their anticholinesterasic activity. Here we show that THA is taken up in rat lysosomes in an energy-dependent manner, and that it is also accumulated in acidic compartments of rat thymocytes and neuroblastoma cells. A concentration of THA less than 1 mM dissipated the pH gradient (delta pH) in all the above ...

Kadin [6] showed that if the Polynomial Hierarchy (PH) has infinitely many levels, then for all k, PSAT[k] ⊂ PSAT[k+1]. This paper extends Kadin’s technique and shows that a proper query hierarchy is not an exclusive property of NP complete sets. In fact, for any A ∈ NP − l̂ow3, if PH has infinitely many levels, then PA[k] ⊂ PA[k+1]. Moreover, for the case of parallel queries, PA‖[k+1] is not ev...

1.1. Random walk in random potential. Let S = (S(n))n∈N0 be a nearestneighbor random walk on the lattice Zd, with start at the origin and drift h into the direction of the first axis. We suppose S being defined on a probability space (Ω,F , Ph), and we denote by Eh the associated expectation. Such a random process is characterized by the distributions of its finite-step sub-paths S[n] def = S(0...

With the arrival of km3 volume scale neutrino detectors the chances to detect the first astronomical sources of TeV neutrinos will be dramatically increased. While the theoretical estimates of the neutrino fluxes contain large uncertainties, we can formulate the conditions for the detectability of certain neutrino sources phenomenologically. In fact, since most galactic neutrino sources are tra...

In this paper we study homogenization of quasi-linear partial differential equations of the form −div (a (x, x/εh, Duh)) = fh on Ω with Dirichlet boundary conditions. Here the sequence (εh) tends to 0 as h → ∞ and the map a (x, y, ξ) is periodic in y, monotone in ξ and satisfies suitable continuity conditions. We prove that uh → u weakly in W 1,p 0 (Ω) as h → ∞, where u is the solution of a hom...
