In the present work we explicate the application of maximum likelihood inference in the analysis of surveys which are the result of (possibly informative) stratified sampling. In Section 1 we review basic ideas, including two general results useful for applying maximum likelihood to sample data. Ideas are illustrated by a simple through the origin regression model. In Section 2, we discuss the ...

In this work various construction character/frequency information sharing structure approaches are proposed in order to optimize transposition_invariant distance evaluation, [SD87], that distance is used to construct a Burkhard-keller tree, [BK73] and [NK82], where is organized a dictionary of strings token over a characters alphabet [SP88], to achieve searchings of strings best matching one on...

The natural sum operation for symplectic manifolds is defined by gluing along codimension two submanifolds. Specifically, let X be a symplectic 2n-manifold with a symplectic (2n − 2)submanifold V . Given a similar pair (Y, V ) with a symplectic identification V = V and a complex anti-linear isomorphism between the normal bundles of V and V , we can form the symplectic sum Z = X# V=V Y . This no...

Let X be a smooth, projective algebraic variety over an algebraically closed field k, and let H(X) denote a Weil cohomology theory. The existence of algebraic cycles on X×X inducing as correspondences the various Künneth projectors π : H(X) → H (X) is one of the standard conjectures of Grothendieck, [9], [10]. It is known in general only for the cases i = 0, 1, 2d−1, 2d where d = dimX. The purp...

Communication complexity was introduced by Yao in 1979. In this model, there are two parties, Alice and Bob, who have access to strings x and y, respectively, where x, y ∈ {0, 1}. The aim is for them to compute a function f : {0, 1} → {0, 1} with as little communication between them as possible. The minimum k for which there exists a protocol that uses at most k bits of communication to compute...

As a consequence of QCD factorization theorems, a wide variety inclusive and exclusive cross sections may be formulated in terms of a universal colour dipole cross section at small-x. It is well known that for small transverse-size dipoles this cross section is related to the leading-log gluon density. Using the measured pion-proton cross section as a guide, we suggest a reasonable extrapolatio...

Middle Jurassic fluvio-deltaic and turbiditic mudstones of the Kashafrud Formation, are important hydrocarbon sources in the gas-rich Kopet-Dagh Basin, northeast Iran. Clay mineral assemblages are important for interpretation of sediment provenance and for understanding burial diagenetic cementation in sandstones. The clay mineral assemblages in mudrocks in two areas, Saleh-Abad and Senjedak, w...

We introduce 3-irreducible modules, even roots and odd roots for Leibniz algebras, produce a basis for a root space of a Leibniz algebra with a semisimple Lie factor, and classify finite dimensional simple Leibniz algebras with Lie factor sl2. In this paper, all vector spaces are vector spaces over an algebraically closed field k of characteristic 0. This paper consists of three sections. In Se...
