Nilpotent Spacelike Jorden Osserman Pseudo-riemannian Manifolds
Pseudo-Riemannian manifolds of balanced signature which are both spacelike and timelike Jordan Osserman nilpotent of order 2 and of order 3 have been constructed previously. In this short note, we shall construct pseudo-Riemannian manifolds of signature (2s, s) for any s ≥ 2 which are spacelike Jordan Osserman nilpotent of order 3 but which are not timelike Jordan Osserman. Our example and tech...
متن کاملUser - De ned Association
Discovering interesting associations of events is an important data mining task. In many real applications, the notion of association, which deenes how events are associated, often depends on the particular application and user requirements. This motivates the need for a general framework that allows the user to specify the notion of association of his/her own choices. In this paper we present ...
متن کاملFinal Report: NED Vis
Integrating neuroscientific data across labs is a challenging endeavour, and extracting meaning from this data is even harder still. NeuroElectro.org collects electrophysiology, neuron type, and experimental conditions data from published articles and provides all of this data in text format for analysis. Here, we present NeuroElectro Data’s Visualization (NED Vis), an interactive visual interf...
متن کاملSpeaker 1: Ned Kalin, USA
Posttraumatic stress disorder is characterized by the failure of the acute fear response to diminish after exposure to a lifethreatening traumatic event. Risk factors for PTSD include sex (female), education (less), and familial and genetic factors, as well as factors pertaining to the type and severity of trauma(s) experienced by the individual over time (including childhood maltreatment). The...
متن کاملParallel Adaptively Re ned Sparse
A parallel version of a nite diierence discretization of PDEs on sparse grids is proposed. Sparse grids or hyperbolic crosspoints can be used for the eecient representation of solutions of a boundary value problem, especially in high dimensions , because the number of grid points depends only weakly on the dimension. So far only thècombination' technique for regular sparse grids was available o...
