Genera/ constraints on the interpretation of image curves are described and implemented We illustrate the use of these constraints to interpret three dimensional structure from an image up to the volumetric level These constraints do not use any knowledge regarding the specific objects in the image, but rely on general assumptions regarding illumination, occlusion, object geometry, and the imag...

Let f, g : X → G/K be maps from a closed connected orientable manifold X to an orientable coset space M = G/K where G is a compact connected Lie group, K a closed subgroup and dimX = dimM . In this paper, we show that if L(f, g) = 0 then N(f, g) = 0; if L(f, g) 6= 0 then N(f, g) = R(f, g) where L(f, g), N(f, g), and R(f, g) denote the Lefschetz, Nielsen, and Reidemeister coincidence numbers of ...

Transitions between states up to spin 16' populated in the ' Nd(a, 4n) reaction were observed using y-y coincidence, y-ray angular distribution and excitation function, and delayed y-ray measurements. A level scheme was constructed up to 6.2 MeV with all levels above 3.8 MeV observed for the first time. Levels below 4.1 MeU were interpreted in terms of the coupling between two extra-core neutro...

Given two maps f1, f2 : M −→ N between manifolds of the indicated arbitrary dimensions, when can they be deformed away from one another? More generally: what is the minimum number MCC(f1, f2) of pathcomponents of the coincidence space of maps f ′ 1 , f ′ 2 where f ′ i is homotopic to fi, i = 1, 2 ? Approaching this question via normal bordism theory we define a lower bound N(f1, f2) which gener...

Overlap coincidence is an equivalent criterion to pure discrete spectrum of the dynamics of self-affine tilings in R. In the case of d = 1, strong coincidence on m-letter irreducible substitution has been introduced in [10, 8] which implies that the system is metrically conjugate to a domain exchange in Rm−1. However being a domain exchange does not imply the property of pure discrete spectrum ...

Introduction: Pharmacokinetic (PK) modeling of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely applied in tumor diagnosis and treatment evaluation. Precision analysis of the estimated PK parameters is essential when they are used as a measure for therapy evaluation or treatment planning. In this study, the accuracy of PK parameters in brain DCE...
