The 'KABF conjecture states that double relative K-theory and cyclic homology agree, at least in characteristic zero. We show that K 2 (A, B, I) maps onto HC 1 (A, B, I) whenever A-* B is a map of Q-algebras and I ~ BIB. We also reinterpret the KABI conjecture in terms of the injectivity of the inverse limit of the map from NK(A, B, I) to the inverse limit of the truncated polynomial versions o...

This paper introduces two shon-time spectral amplitude estimators for speech enhancement with multiple microphones. Based on joint Gaussian models of speech and noise Fourier coefficients the clean speech amplitudes are estimated with respect to the MMSE or the MAP criterion. The estimators outperform single microphone minimum mean square amplitude estimators when the speech is highly correlate...

We examine a special case of an approximation the joint spectral radius given by Blondel and Nesterov, which we call outer radius. The is square root ordinary n2 matrix $$\sum \overline {{X_i}} \otimes {X_i}$$ ∑ X i ¯ ⊗ . give analogue formula for can be used to quickly obtain error bounds in methods based on work Nesterov. analyze iterates completely positive map, including quantum channels. a...

This paper introduces two short-time spectral amplitude estimators for speech enhancement with multiple microphones. Based on joint Gaussian models of speech and noise Fourier coefficients, the clean speech amplitudes are estimated with respect to the MMSE or the MAP criterion. The estimators outperform single microphone minimum mean square amplitude estimators when the speech components are hi...

Let P be a planar map. To be more concrete, let P be a partition of the unit square into triangles (i.e., a mesh). Since any simple polygon can be triangulated, P can represent any planar map, and its partition of the unit square into different regions, with different properties. For the sake of simplicity, assume that every vertex in P shares at most, say, nine triangles. Let us assume that we...

The presence of Mycobacterium avium subsp. paratuberculosis (MAP) in non-ruminant wildlife has raised questions regarding the role of these species in Johne's disease transmission. In this study we tested 472 tissues from 212 animals of six different species of scavenging mammals. All animals were taken from within a 210-square-mile area in Dane and Iowa counties of south central Wisconsin from...

To date, it has been shown that cognitive map representations based on cartographic visualisations are systematically distorted. The grid is a traditional element of map graphics that has rarely been considered in research on perception-based spatial distortions. Grids do not only support the map reader in finding coordinates or locations of objects, they also provide a systematic structure for...

A grazing bifurcation corresponds to the collision of a periodic orbit with a switching manifold in a piecewise-smooth ODE system and often generates complicated dynamics. The lowest order terms of the induced Poincaré map expanded about a regular grazing bifurcation constitute a Nordmark map. In this paper we study a normal form of the Nordmark map in two dimensions with additive Gaussian nois...

the mathematical aspect of cartographic mapping is a process which establishes a unique connection between points of the earth’s sphere and their images on a plane. it was proven in differential geometry that an isometric mapping of a sphere onto a plane with all corresponding distances on both surfaces remaining identical can never be achieved since the two surfaces do not possess the same gau...
