To be successful at manipulating objects one needs to apply simultaneously well controlled movements and contact forces. We present a computational theory of how the brain may successfully generate a vast spectrum of interactive behaviors by combining two independent processes. One process is competent to control movements in free space and the other is competent to control contact forces again...

Esox lucius is an economically important freshwater species. Mitochondrial cytb, 12SrRNA, and 16SrRNA gene sequences were used in order to clarify the genetic variation and population structure in three E. Lucius populations, i.e., one Wild population (W) and two hatchery populations (Hatchery Population I-HPI and Hatchery Population II-HPII). A total of 55 individuals, with 19 from wild and 1...

We have theoretically proposed and experimentally demonstrated that two EPR photon pairs can be transformed into a threephoton W state by local operation and classical communication (LOCC). The fidelity of the final state to the ideal W state was 0.778±0.043. The obtained expectation value of the witness operator for distinguishing between the three-photon W state and bi-separable states was −0...

We prove that the Dirichlet fundamental polyhedron for a cyclic group generated by a unipotent or hyperbolic element y acting on complex hyperbolic «-space centered at an arbitrary point w is bounded by the two hypersurfaces equidistant from the pairs w, yw and w,y~lw respectively. The proof relies on a convexity property of the distance to an isometric flow containing y.

A ternary complementary pair, TCPðn;wÞ; is a pair of ð0;71Þ-sequences of length n with zero autocorrelation and weight w: These are of theoretical interest in combinatorics as well as of practical consequence in coding, transmitting and processing various kinds of signals. When one attempts to construct a TCP of given length and weight, the first thing to decide is where to place the zeros, if ...

In this paper, we deal with the problem of description of nonsingular pairs of compatible flat metrics for the general N -component case. We describe the scheme of the integrating the nonlinear equations describing nonsingular pairs of compatible flat metrics (or, in other words, nonsingular flat pencils of metrics). This scheme was announced in our previous paper [1]. It is based on the reduci...

We study the decays into six quarks of off-shell pairs of W± bosons produced in electronpositron annihilations, through the O(αs) order in the strong coupling constant. We give explicit helicity amplitude formulae. We present numerical results in the context of phenomenological analyses of relevance at LEP2 and future Linear Colliders: such as MW determinations, New Physics and Higgs searches. ...

In this paper, notions of compatible and almost compatible Riemannian and pseudo-Riemannian metrics, which are motivated by the theory of compatible (local and nonlocal) Poisson structures of hydrodynamic type and generalize the notion of flat pencil of metrics (this notion plays an important role in the theory of integrable systems of hydrodynamic type and the Dubrovin theory of Frobenius mani...

Let G be a graph. The Wiener index of G, W (G), is defined as the sum of distances between all pairs of vertices of G. Denote by L i (G) its i-iterated line graph. In the talk, we will consider the equation W (L i (T)) = W (T) where T is a tree and i ≥ 1.
