We introduce the notion of one-sided mapping cones positive linear maps between matrix algebras. These are convex that invariant under compositions by completely from either left or right side. The duals such can be characterized in terms ampliation maps, which also used to characterize many notions quantum information theory—such as separability, entanglement-breaking Schmidt numbers, well dec...

We present a system for painting on an object in a view-dependent way. The user creates paintings of the object from various camera positions to produce a texture map which changes depending upon the view direction. The paintings are blended on the object, as opposed to blending the paintings themselves, to ensure that novel views are correctly interpolated. This also produces self-contained mo...

PURPOSE Both implicit time and amplitude of the cone-mediated electroretinographic (ERG) b-wave differ significantly between the C57BL/6JOlaHsd and 129S2/SvHsd inbred mouse strains. The purpose of this work was to undertake a quantitative genetics study to localize the gene or genes involved. METHODS Implicit time and amplitude of the a- and b-waves of the single-flash and flicker cone-mediat...

Abstract- In this article, the design of conformal antennas has been discussed using the characteristic modes (CM) method. For this purpose, the vector wave function(VWF) has been utilized to achieve a two-dimensional mapping of the conformal antenna. In designing and analyzing of cone-shaped antennas applicable for multi-input multi-output (MIMO) systems, the most important goal is to achieve ...

In this paper we study a special class of convex optimization problems called conically ordered convex programs (COCP), where the feasible region is given as the level set of a vector-valued nonlinear mapping, expressed as a nonnegative combination of convex functions. The nonnegativity of the vectors is defined using a pre-described conic ordering. The new model extends the ordinary convex pro...

We adapt Bar-Natan's scanning algorithm for fast computations in (even) Khovanov homology to odd homology. use a mapping cone construction instead of tensor product, which allows us deal efficiently with the more complicated sign assignments theory. The has been implemented computer program. also determine 3-strand torus links.

Using the mapping cone of a rational surgery, we give several obstructions for Seifert fibered surgeries, including obstructions on the Alexander polynomial, the knot Floer homology, the surgery coefficient and the Seifert and four-ball genus of the knot. These generalize the corresponding results in [9][21].

We show that the gradient mapping of the squared norm of Fischer-Burmeister function is globally Lipschitz continuous and semismooth, which provides a theoretical basis for solving nonlinear second order cone complementarity problems via the conjugate gradient method and the semismooth Newton’s method.

We consider a problem of solution of a multi-valued inclusion on a cone segment. In the case where the underlying mapping possesses Z type properties we suggest an extension of Gauss-Seidel algorithms from nonlinear equations. We prove convergence of a modified double iteration process under rather mild additional assumptions. Some results of numerical experiments are also presented.

Leksell Gamma Knife® IconTM with integrated Cone Beam CT (CBCT) system provides increased workflow flexibility with e.g. planning on frameless images and subsequent frameless dose delivery. The stereotactic reference is given by the CBCT images taken prior to treatment. Co-registration of the planning image volume with the CBCT volume gives the transformation mapping of the planned isocenter po...
