Kaposi's sarcoma (KS) is an angioproliferative disease occurring in several different clinical-epidemiological forms that, however, share the same histological traits and are all associated with infection by the human herpesvirus 8 (HHV8). KS initiates in a context of immune dysregulation characterised by CD8+ T cell activation and the production of Th1-type cytokines that induce a generalised ...

Until now theories of the gesture-speech relationship have been difficult to evaluate because of their descriptive basis. In this paper we provide a tool for investigating the relationship between speech and gesture: a system that generates speech, intonation, and gesture using two copies of an identical program that have different knowledge of the world and must cooperate to accomplish a goal....

Kernel spectral clustering corresponds to a weighted kernel principal component analysis problem in a constrained optimization framework. The primal formulation leads to an eigen-decomposition of a centered Laplacian matrix at the dual level. The dual formulation allows to build a model on a representative subgraph of the large scale network in the training phase and the model parameters are es...

We present an e cient algorithm for solving the \smallest k-enclosing circle" ( kSC ) problem: Given a set of n points in the plane and an integer k n, nd the smallest disk containing k of the points. We present two solutions. When using O(nk) storage, the problem can be solved in time O(nk log 2 n). When only O(n logn) storage is allowed, the running time is O(nk log 2 n log n k ). This proble...
