Batalin-Vilkovisky Integrals in Finite Dimensions

The Batalin-Vilkovisky method (BV) is the most powerful method to analyze functional integrals with (infinite-dimensional) gauge symmetries presently known. It has been invented to fix gauges associated with symmetries that do not close off-shell. Homological Perturbation Theory is introduced and used to develop the integration theory behind BV and to describe the BV quantization of a Lagrangian system with symmetries. Localization (illustrated in terms of Duistermaat-Heckman localization) as well as anomalous symmetries are discussed in the framework of BV.Comment: 35 page

Academic and clinical preparation in speech-language pathology and audiology: a global training consortium

ABSTRACT: Purpose: To describe a research-based global\ud curriculum in speech-language pathology and audiology that\ud is part of a funded cross-linguistic consortium among 2 U.S.\ud and 2 Brazilian universities.\ud Method: The need for a global curriculum in speechlanguage\ud pathology and audiology is outlined, and different\ud funding sources are identified to support development of a\ud global curriculum. The U.S. Department of Education’s Fund\ud for the Improvement of Post-Secondary Education (FIPSE), in\ud conjunction with the Brazilian Ministry of Education (Fundacao\ud Coordenacao de Aperfeicoamento de Pessoal de Nivel\ud Superior; CAPES), funded the establishment of a shared\ud research curriculum project, “Consortium for Promoting\ud Cross-Linguistic Understanding of Communication Disabilities\ud in Children” for East Tennessee State University and the University of Northern Iowa and 2 Brazilian universities\ud (Universidade Federal de Santa Maria and Universidade de\ud São Paulo-Baurú).\ud Results: The goals and objectives of the research-based\ud global curriculum are summarized, and a description of an\ud Internet-based course, “Different Languages, One World,” is\ud provided\ud Conclusion: Partnerships such as the FIPSE–CAPES consortium\ud provide a foundation for training future generations of\ud globally and research-prepared practitioners in speechlanguage\ud pathology and audiology.U.S. Department of Education Fund for the Improvement of Post-Secondary Education P116M100014Brazilian Ministry of Education Fundacao Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior 094/1

Status of the Superconducting Magnets for FAIR

Silicon microdosimetry measurements in Fast Neutron Therapy were simulated using the GEANT4 Monte Carlo toolkit. The possibility of using silicon microdosimeters for verification of Monte Carlo based treatment planning systems in hadron therapy is suggested

Generalized Force Model of Traffic Dynamics

Floating car data of car-following behavior in cities were compared to existing microsimulation models, after their parameters had been calibrated to the experimental data. With these parameter values, additional simulations have been carried out, e.g. of a moving car which approaches a stopped car. It turned out that, in order to manage such kinds of situations without producing accidents, improved traffic models are needed. Good results have been obtained with the proposed generalized force model.Comment: For related work see http://www.theo2.physik.uni-stuttgart.de/helbing.htm

Status Of The FAIR Synchrotron Projects SIS18 And SIS100

A large fraction of the program to upgrade the existingheavy ion synchrotron SIS18 as injector for the FAIR synchrotron SIS100 has been successfully completed. With the achieved technical status, a major increase of theaccelerated number of heavy ions could be reached. Thenow available performance especially demonstrates thefeasibility of high intensity beams of medium charge stateheavy ions with a sufficient control of the dynamicvacuum and connected charge exchange loss. Two furtherupgrade measures, the installation of additional magneticalloy (MA) acceleration cavities and the exchange of themain dipole power converter, are presently beingimplemented. For the FAIR synchrotron SIS100, theprocurement of all major components with longproduction times has been started. With the delivery andtesting of several pre-series components, the phase ofoutstanding technical reserach and developments could becompleted and the readiness for series productionachieved
