Some explorations in holomorphy.
In supersymmetric theories, one can obtain striking results and insights by exploiting the fact that the superpotential and the gauge coupling function are holomorphic functions of the model parameters. The precise meaning of this holomorphy is subtle, and has been explained most clearly by Shifman and Vainshtein, who have stressed the role of the Wilsonian eeective action. In this note, we ela...
متن کاملBrief Notes on Recent Anthropological Explorations Under the Auspices of the Smithsonian Institution and the U. S. National Museum.
In the April and July (1915) numbers of these PROCEEDINGS I have given notes on 'Some Recent Anthropological Explorations' carried out under the auspices of the Smithsonian Institution, and on 'An Exhibit in Physical Anthropology' which was prepared on the basis of these explorations for the Panama-California Exposition; I will now complete the account by referring in brief to the scientific re...
متن کاملEvolving Finite State Transducers: Some Initial Explorations
Finite state transducers (FSTs) are finite state machines that map strings in a source domain into strings in a target domain. While there are many reports in the literature of evolving general finite state machines, there has been much less work on evolving FSTs. In particular, the fitness functions required for evolving FSTs are generally different to those used for FSMs. This paper considers...
متن کاملParallelizing Probabilistic Inference: Some Early Explorations
We report on an experimental investigation into opportunities for parallelism in belief net inference. Specifically, we report on a study performed of the available parallelism, on hypercube style machines, of a set of ran domly generated belief nets, using factoring (SPI) style inference algorithms. Our results indicate that substantial speedup is available, but that it is available only thr...
متن کاملRecent Work on Culture and Schizophrenia: Epidemiological and Anthropological Approaches
Schizophrenia is observed worldwide in diverse cultures. However as Abed & Abbas [1] note, the supposed universality of the incidence and prevalence of schizophrenia has been seriously challenged. It is now widely accepted that the life-time prevalence and incidence of this disorder vary considerably in time and place. A lower, 50% concordance between identical twins suggests that environmental...
