The two main kinds of nuclear fusion devices are based on Magnetic Confinement Fusion (MCF), like the Tokamak design, and Inertial Confinement Fusion (ICF), like the NIF design using intense lasers. An improved understanding of plasma physics over the last 20 years and the huge technical difficulties in designing MCF and ICF reactors, has re-awoken the interest in several alternative reactor designs, in particular in those that capitalize on the increased stability of Field Reversed Configurations (FRC) with increased currents. In this vein, General Fusion, a company from Vancouver, has embarked since 2002 on a project of implementing a device based on Magnetic Target Fusion (MTF) first proposed in the 80s by researchers at the US Naval Weapons Research Lab. This approach is an intermediate approach between MCF (low plasma density, very strong magnetic fields, large confinement times) and ICF (high plasma density, very intense lasers, short confinement times). The Post-Doc general objectives will be to numerically validate the chosen physical models of some essential physics within General Fusion's device thereby i) providing numerical proof-of-concept ii) reducing operating uncertainties and iii) optimizing reactor design. Specialized numerical codes, often classified, exist for the simulation of specific reactor designs (MCF or ICF) but not for MTF. The Post-Doc will then adapt existing High-Performance codes for Hydrodynamics, namely Frontier [http://frontier.ams.sunysb.edu/news/news.php ], in order to address important questions about plasma instabilities during compression, Lawson's criterion, vortex collapses. Details on General Fusion's reactor can be found on [http://www.generalfusion.com]. Keywords: Hydrodynamics, Bifluid Flows, FronTier, Front-Tracking, Rayleigh-Taylor Instabilities, High Performance Computing. Requirements: A PhD in one of the following areas is required: Applied Mathematics, Physics, Mechanical or Electrical Engineering. Applicants should have a strong background in Scientific Computing ideally applied to Fluid Dynamics. Supervision: This position will be funded by MITACS and General Fusion and will part of a MITACS Cluster project. It will be co-supervised by Marc Laforest (Ecole Polytechnique de Montreal), Emmanuel Lorin (Carleton University), and Frederic Sirois (Ecole Polytechnique de Montreal). The student could be registered at Carleton University or Ecole Polytechnique de Montreal. Frequent visits in Vancouver are expected. Starting date: July 2010 Salary: $36,000 per year.

The CIRM (Centro Internazionale per la Ricerca Matematica), through its new Comitato Direttivo, formed by: Fabrizio Catanese (Bayreuth University), Director, Luigi Ambrosio (Scuola Normale Superiore di Pisa), Marco Andreatta (Trento University), Fritz Grunewald (Duesseldorf University), Alberto Valli (Trento University), Don Zagier (Max Planck Institut, Bonn and College de France, Paris), took this transformation as an occasion to expand the spectrum of the CIRM activities, held since many years in collaboration with the University of Trento. Next to the traditional activity, which has seen the CIRM organize more than 210 mathematical Meetings and Conferences in the period 1979-2007, and the related editorial activity, which has seen the publication of more than 50 research books and journal volumes, the Comitato Direttivo set up a new range of activities, especially four types of visiting positions with the intention of stimulating the interaction between the mathematical research community of the Trento area and the European and international mathematical community. The hope is that this new and important initiative may in the future bring the Trento CIRM to be in line with other European Mathematical Research Centres. One of the targeted purposes is to have foreign visitors spending part of their sabbatical at the CIRM, bringing new experiences and exciting new developments in contact with the mathematical environment of the Trento area. These visitors will receive a more than full reimbursement (see below) of the expenses connected with their stay in Trento. It is moreover agreed upon that the support of younger researchers is one of the vital functions of a research centre. In this direction, the CIRM opens the application for two Postdoc Positions. I) Postdoc Fellowships The CIRM offers two annual Postdoc Fellowships for researches in the field of Mathematics in the year 2010-2011. Each fellowship amounts to Euro 23500 gross per year (taxes should be deducted), which will be pro-rated in 12 monthly installments, and requires the presence in the CIRM Institute (address Via Sommarive 14, Povo, Trento). The applications must arrive not later than September 10th, 2010 at the address Fondazione Bruno Kessler, Centro Internazionale per la Ricerca Matematica, Via Sommarive n. 14 - Povo, 38123 Trento by ordinary mail or via electronic mail to the address micheletti@fbk.eu. The Comitato Direttivo of CIRM will make a selection of winner applicants, ranking them in consecutive order. On the basis of this list of selected candidates, the CIRM will make offers to award the fellowships (as "contratto di collaborazione coordinata e continuativa a progetto"). These fellowships are incompatible with other full-time employment or with similar fellowships. Winners must communicate their acceptance of the fellowship within 15 days from the time of receipt of the communication of CIRM. If one of the chosen candidates turns down the offer, the CIRM will proceed to make an offer to the next candidate on the list. The activities connected with the new enrollment, except for particular requirements to be agreed upon with the winners, will start preferably on November 2nd, but possibly also before or after, in any case before November 30th, 2010. Applications for Postdoctoral Fellowships may also be submitted before the official awarding of the Ph.D. title (or equivalent), but under a solid guarantee that the title will be awarded before the last deadline (November 30th, 2010). In any case the title should have been awarded before the beginning of the activity at the CIRM. Applicants must send by ordinary mail, or possibly by electronic mail to the address micheletti@fbk.eu , the following documents: 1. A curriculum vitae including surname, first name and postal address (e-mail address too) chosen to correspond with CIRM, together with three recommendation letters. 2. A detailed Research Program with explicit reference to either a Professor of Trento University, or a member of the Comitato Direttivo of CIRM. The applicant's program must be related to the Research Group of the Host Professor. 3. A list of publications. 4. Copies (possibly, electronic files) of recent articles and preprints. 5. A copy (possibly, electronic file) of the Doctoral Thesis; in case of submission of a preliminary version a statement by the Ph.D. advisor should be attached. The Comitato Direttivo of CIRM will make a selection of winner applicants, ranking them in consecutive order, and with a preference for Research Programs connected to the research activity at CIRM and at the Universita di Trento. It is expected that the results of the selection process will be communicated to the applicants within October 5th, 2010. If one of the chosen candidates has not yet been awarded the Ph.D. title within the date agreed upon for commencing the activity at the CIRM, the Comitato Direttivo will proceed to make an offer to the next candidate on the list. The fellows will have access, free of charge, at the FBK Cafeteria in Povo. CIRM will provide the necessary logistic support: office space and computer facilities, access to the library and to other facilities of the Department of Mathematics of the Universita di Trento and of the Fondazione Bruno Kessler. II) CIRM Visiting Professors and CIRM Visiting Scholars CIRM Visiting Scholars will perform mathematical research in cooperation with scientists and researchers of Trento University or, more generally, of the Trento area, holding some research seminars; CIRM Visiting Professors will hold short Ph.D. courses, or 'Summer Courses', or series of seminars. It is foreseen that the selection process for Visiting Professors-Scholars take place through either i) individual application, or ii) invitation by a professor of Trento University or by a member of the Comitato Direttivo. In both cases, as a rule, the applications-proposals must be motivated on the basis of cooperation or synergy with Mathematicians belonging to Institutions which are related with Trento. Applications must be sent to the address FBK, Centro Internazionale per la Ricerca Matematica, Via Sommarive n. 14-Povo, 38123 Trento, Italy by ordinary mail or via electronic mail to the address micheletti@fbk.eu. Applications must also contain a specific indication of the proposed dates for the visit (usually: between 15 days and three months); it is possible to enclose recommendation letters. Applications and proposals may be sent at any time. However, it is recommended to submit them sufficiently ahead of time, since they will be usually examined three times every year. Three levels of remuneration are foreseen, according to the corresponding career level and the period of staying at CIRM. All levels include a full coverage of expenses, preferably by direct payment by the FBK-CIRM administration, travel reimbousement, and a honorarium (subject to taxation), up to a maximum of: Level I) Euro 3000, all inclusive, per month. Level II) Euro 3500, all inclusive, per month. Level III) Euro 4000, all inclusive, per month. CIRM will provide the necessary logistic support: office space and computer facilities, access to the library and to other facilities of the Dipartimento di Matematica della Universita di Trento, and of the Fondazione Bruno Kessler (such as FBK Cafeteria). III) Research in Pairs This type of program is similar to the one of the Mathematisches Forschungsinstitut Oberwolfach, and provides for the presence of two or three partners from Universities located in different towns, who intend to work on a definite research project and for a well specified period of time (ranging from one to six weeks). Applicant partners must submit a scientific project in the field of mathematics, with a detailed research program, resulting in one or more scientific publications in journals of excellent mathematical level; the support of the CIRM will then be acknowledged in the resulting publications. Participants in the RIP Program will also give occasional research seminar talks at the CIRM or at the University of Trento, but will enjoy freedom in the pursuit of their scientific goals. Applications where one or more of the partners are Italians will of course be welcome. CIRM will provide the necessary logistic support: office space and computer facilities, access to the library and to other facilities of the Dipartimento di Matematica della Universita di Trento, and of the Fondazione Bruno Kessler (such as FBK Cafeteria). Participants in the RIP Program will have their living expenses (full board and lodging) fully paid by CIRM and will possibly get an insurance covering their activity inside the CIRM offices. As a rule, travel expenses will not be reimbursed, except in exceptional cases. Applications must be sent to the address FBK, Centro Internazionale per la Ricerca Matematica, Via Sommarive n. 14-Povo, 38123 Trento, by ordinary mail or possibly via electronic mail to the address micheletti@fbk.eu. Applications can be submitted at any time, but preferably a few months before the planned stay, since decision making might require up to three months or more. Applicants are asked to submit, together with their application, a brief description of their research proposal, their C.V.'s, a list of publications, and possibly electronic copies of some recent articles. They must specify in detail the dates of their intended visit. The Director of CIRM Prof. Fabrizio Catanese The Visitors program (RIP included) will be run by the Comitato Direttivo of CIRM in a similar way to the one of the Editorial Committee of a scientific journal. Proposals can be sent either by ordinary mail or by electronic mail, and will be discussed by the Comitato Direttivo per e-mail, possibly asking for experts' opinions on the submitted proposals. ------ Subject: Contents, Networks and Heterogeneous Media 5:3 From: "Liwei Ning" Date: Tue, 13 Jul 2010 14:34:05 -0500 Networks and Heterogeneous Media (NHM) Volume: 5, Number: 3 September 2010 http://aimsciences.org/journals/displayPapers1.jsp?pubID=378 We offer a couple of weeks free online access to the full paper of NHM 5-3, A special issue New Trends in Model Coupling, Theory, Numerics and Applications.
