The topical area is important to many fields of optics, as well as a broader constituency due to its interdisciplinary nature; examples include digital image reconstruction from Fourier intensity measurements, superresolution, tomographic reconstruction and blind deconvolution. This topical meeting is concerned with theory, algorithms and applications of signal recovery and synthesis in optics and other disciplines.

Founder of the prize is the Bavarian Graduate School of Computational Engineering (BGCE, http://www.bgce.de/), a consortium offering an honors track to the best students of three international master's programs in Computational Engineering at Technische Universitaet Muenchen (TUM) and Universitaet Erlangen-Nuernberg (FAU). The prize will be awarded for outstanding student work in the field of CS&E, and the winner will be invited to spend one week (air fare and lodging expenses covered) in Bavaria, visiting FAU and TUM (one of the three German universities having recently succeeded in the federal excellence initiative) and getting in contact with BGCE's educational and research program, one of the most advanced ones in Europe. The main objective is to promote excellent students in CS&E and to foster international exchange at an early career stage. Eligible for the prize will be undergraduate students as well as graduates prior to receiving their PhD (at date of submission). Candidates are required to summarize their work in a short paper of at most 4 pages and to present their work at SIAM CSE 2007 with a talk to be given in the special "CSE Student Prize Minisymposium". Excluded from the competition are only students from our own universities, FAU and TUM. Deadline for application is December 31, 2006. Submissions should be sent in pdf format by e-mail to bungartz@in.tum.de or ruede@cs.fau.de Since we are interested in a broad and high-level competition, we ask you to encourage suitable candidates in your group or department to submit a paper and to support their participation in SIAM CSE 2007. Your support is appreciated!

Scientific Computing Special Issue on Computational Science & Engineering http://www10.informatik.uni-erlangen.de/~ruede/SISC-CSE.html Guest Editors-in-Chief: Chris Johnson, University of Utah David Keyes, Columbia University Ulrich Ruede, Universitaet Erlangen-Nuernberg Call for papers: Computational Science and Engineering (CS&E) is a rapidly growing multidisciplinary field that employs advanced computation to understand and solve complex problems. Recognizing the growing importance of and interest in CS&E, the SIAM Journal on Scientific Computing (SISC) will devote a special issue to innovative research papers in CS&E. The guest editors are seeking papers that tackle problems from the real world and make a research contribution in one or more of the techniques of CS&E. Papers should illustrate new and useful techniques and tools for solving realistic problems, which often have complicated three-dimensional geometries, multiple scales, heterogeneities, anisotropies, and multi-physical or biological descriptions. Though such problem domains often thwart proofs of accuracy or efficiency, papers should address validation and verification through reduction to analyzable cases and convergence studies, as applicable, and comparisons with alternative approaches. Deadlines: The deadline for submission of papers is April 30, 2007, following the SIAM Conference on CS&E: http://www.siam.org/meetings/cse07/ Review Process: Papers will be subject to review according to SISC standards by a guest Editorial Board. Submission: All interested should submit a manuscript and cover letter via SISC's online submission site.
