The aim of this paper is to give effective inequalities in the form of K X ≥?pg(X) −?, where X is a minimal projective 3-fold of general type with at worst Q-factorial terminal singularities. Our method is quite effective in the sense that we have found the optimal form of Noether’s inequality: K X ≥ 4 3 pg(X) − a with a ∈ [ 10 3 , 14 3 ] among smooth canonical models. An interesting applicatio...

A 3-dimensional model dual to the Rozansky-Witten topological sigma-model with a hyper-Kähler target space is considered. It is demonstrated that a Feynman diagram calculation of the classical part of its partition function yields the Milnor linking number.

The reconstruction of broken artifacts is a common task in archeology domain; it can be supported now by 3D data acquisition device and computer processing. Many works have been dedicated in the past to reconstructing 2D puzzles but very few propose a true 3D approach. We present here a complete solution including a dedicated transportable 3D acquisition set-up and a virtual tool with a graphic...

The latent variable "δ" (for "dementia") has been proposed as a phenotype for all cause dementia. δ is extracted from cognitive batteries by a specific confirmatory factor analysis in a structural equation modeling framework. δ appears to be uniquely responsible for cognition's association with functional status. Because it is extracted from Spearman's general intelligence factor "g", this has ...

3D Segments and 3D Facets information Didier Gemmerl e CRIN/CNRS { INRIA Lorraine Bâtiment LORIA, Campus Scienti que, B.P. 239 54506 Vand uvre CEDEX, FRANCE Abstract Given a serie of trinocular images of an object, we have developed a method for building 3D Facets and 3D segments model of the object. From each triplet, a partial description of the object, called 3D View, is extracted. From the ...

A tissue P system with cell division is a computing model which has two basic features: intercellular communication and the ability of cell division. The ability of cell division allows us to obtain an exponential amount of cells in linear time and to design cellular solutions to computationally hard problems in polynomial time. In this work we present an efficient solution to the tripartite ma...

A new Digital Terrestrial Television service based on transmission and visualization of 3D images is presented. This service has been designed to be suitable for domestic users without relevant increase of the final cost for the spectator, being the production of the programs what is modified to generate adequate 3D TV signals. The systems that make possible the implementation of the service ha...

This paper gives a classification up to isotopy of automorphisms (self-homeomorphisms) of 3-dimensional handlebodies and compression bodies, analogous to the Nielsen-Thurston classification of automorphisms of surfaces. Indecomposable automorphisms analogous to pseudo-Anosov automorphisms are identified and called generic. The first steps are taken towards understanding generic automorphisms us...

An automated method to register three-dimensional Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) brain images is presented. In a first step, mathematically well founded differential operators in scale space are applied to 2D or 3D CT and MRI images resulting in feature images depicting ’ridgeness’. In a second step, a fully automatic hierarchical correlation scheme is applied to ...
