In this article, the Lorentzian manifolds isometrically embeddable in L N (for some large N , in the spirit of Nash's theorem) are characterized as a a subclass of the set of all stably causal spacetimes; concretely, those which admit a smooth time function τ with |∇τ | > 1. Then, we prove that any globally hyperbolic spacetime (M, g) admits such a… (More)
Object similarities are now more and more characterized by connectivity information available in form of network or graph data. Complex graph data arises in various fields like e-commerce, social networks, high throughput biological analysis etc. The generated interaction information for objects is often not simply binary but rather associated with… (More)
The study sought to establish cross-test validity for The Teddy Bears' Picnic (TBP), which assesses the internal personal constructs of the troubled child. After showing that the TBP could discriminate between 4-year-olds who were above and below cut-off on the Preschool Behaviour Checklist, the research demonstrated that both tests could distinguish levels… (More)
The case of an XX male suffering from paranoid schizophrenia is presented. Findings in the development of the personality and the illness in this patient support the theory that XX males are genetically similar to XXY males.
