"Nearly" Generic Monitoring and Control Programs Maintain Beam Quality

We describe a tool chain that enables experimentation and study of real C++ applications. Our tool chain enables reverse engineering and program analysis by exploiting gcc, and thus accepts any C++ application that can be analysed by the C++ parser and front end of gcc. Our current test suite consists of large, open-source applications with diverse problem domains, including language processing and gaming. Our tool chain is designed using a GXL-based pipe-filter architecture; therefore, the individual applications and libraries that constitute our tool chain each provide a point of access. The preferred point of access is the g4api Application Programming Interface (API), which is located at the end of the chain. g4api provides access to information about the C++ program under study, including information about declarations, such as classes (including template instantiations); namespaces; functions; and variables, statements and some expressions. Access to the information is via either a pointer to the global namespace, or a list interface

Charges of Exceptionally Twisted Branes

The charges of the exceptionally twisted (D4 with triality and E6 with charge conjugation) D-branes of WZW models are determined from the microscopic/CFT point of view. The branes are labeled by twisted representations of the affine algebra, and their charge is determined to be the ground state multiplicity of the twisted representation. It is explicitly shown using Lie theory that the charge groups of these twisted branes are the same as those of the untwisted ones, confirming the macroscopic K-theoretic calculation. A key ingredient in our proof is that, surprisingly, the G2 and F4 Weyl dimensions see the simple currents of A2 and D4, respectively.Comment: 19 pages, 2 figures, LaTex2e, complete proofs of all statements, updated bibliograph

Modifications to the Machine Optics of BESSY II Necessitated by the EMIL Project

The Helmholtz Zentrum Berlin and the Max Planck Society are going to build a new dedicated X ray beam line at the synchrotron light source BESSY II which will be used for analyzing materials for renewable energy generation. The new large scale project has been dubbed EMIL. In this document we present the modifications to the machine optics and to what extent these changes affect the performance of BESSY I
