Area distances of convex plane curves and improper affine spheres
(Siam Publications, 2008)
The area distance to a convex plane curve is an important concept in computer vision. In this paper we describe a strong link between area distances and improper affine spheres. Based on this link, we propose an extremely ...
Affine skeletons and monge-ampere equations
(Siam Publications, 2009)
An important question about a. ne skeletons is the existence of differential equations that are related to the 'affine distance' and the 'area distance' (hence to a. ne skeletons) in the same way the Eikonal equation is ...
A geometric representation of improper indefinite affine spheres with singularities
(2011)
Given a pair of planar curves, one can define its generalized area distance, a concept that generalizes the area distance of a single curve. In this paper, we show that the generalized area distance of a pair of planar ...
A fast marching method for the area based affine distance
(Springer, 2008-01)
In a previous paper, it was proved that the area based affine distance of a convex region in the plane satisfies a non-homogeneous Monge-Ampere differential equation. Based on this equation, in this paper we propose a fast ...
Affine properties of convex equal-area polygons
(Springer, 2012-10)
In this paper we discuss some affine properties of convex equal-area polygons, which are convex polygons such that all triangles formed by three consecutive vertices have the same area. Besides being able to approximate ...
Affinity and distance. On the Newtonian structure of some data kernels
(De Gruyter Open Ltd, 2018-02)
Let X be a set. Let K(x, y) > 0 be a measure of the affinity between the data points x and y. We prove that K has the structure of a Newtonian potential K(x, y) = φ(d(x, y)) with φ decreasing and d a quasi-metric on X under ...
Approximating parametric curves with strip trees using affine arithmetic

INCREASED CALCIUM AFFINITY OF A FUCOSYLATED CHONDROITIN SULFATE FROM SEA-CUCUMBER
(Elsevier B.V., 1994-04-01)
Calcium binding and charge distribution on a fucosylated chondroitin sulfate and a standard chondroitin 6-sulfate have been studied using a metallochromic indicator and conductimetric titrations. The fucosylated chondroitin ...

Calcium binding and charge distribution on a fucosylated chondroitin sulfate and a standard chondroitin 6-sulfate have been studied using a metallochromic indicator and conductimetric titrations. The fucosylated chondroitin ...
Dynamic Modulation of Binding Affinity as a Mechanism for Regulating Interferon Signaling
(Academic Press Ltd - Elsevier Science Ltd, 2017-08)
How structural dynamics affects cytokine signaling is under debate. Here, we investigated the dynamics of the type I interferon (IFN) receptor, IFNAR1, and its effect on signaling upon binding IFN and IFNAR2 using a ...
