We have decided to use to to enable the participation of a number of young US-based colleagues at the forthcoming workshop on "Effective computational methods for highly oscillatory problems: The interplay between mathematical theory and applications" (2--6 July 2007, http://www.newton.cam.ac.uk/programmes/HOP/hopw05). The grant will cover the full "workshop package" of local expenses (room and full board, workshop fees, workshop dinner) but not travel. Having said so, participants might find it convenient to combine their travelling arrangements with any of several other conferences and meetings held in Western Europe in close time proximity. Anybody interested should email Arieh Iserles (ai@damtp.cam.ac.uk) as soon as possible, enclosing a brief CV. Explaining (briefly, please) how will you benefit from the workshop will come useful. In case you would like to offer a talk or a poster (neither is a condition for funding!), please enclose a (tentative) title and abstract. ------ Subject: Climate Modelling Summer School: grants available From: Nikos Nikiforakis Date: Tue, 24 Apr 2007 11:32:35 -0400 Full grants are available (see below for eligibility criteria) for a two-week summer school at the University of Cambridge on the development and use of climate models. The school will provide a solid foundation on the algorithms, numerical methods and techniques suitable for the design and operation of modern climate models and the analysis of their results. Elements of the dynamics and physics of the climate system are an integral part of the school. The schedule includes lectures, daily hands-on computing practical sessions and seminars from practitioners. It is highly recommended for early-career scientists (advanced Ph.D. and/or post-docs) who are interested to pursue research in climate modelling. Registration deadline: May 31, 2007 The school operates under the auspices of the of the UK-Japan Climate Collaboration and is supported by the UK Foreign and Commonwealth Office and the National Centre for Atmospheric Science (UK-HiGEM programme). Dates: September 10, 2007 - September 21, 2007 Location: Centre for Mathematical Sciences, Cambridge, United Kingdom Accommodation: Selwyn College. Web Page: http://www.earthsimulator.org.uk/ (follow the link for Summer School) Eligibility: The school will consider applications from PDRAs and PhD students who are either funded by the UK Research Councils or are Japanese Nationals. However, participants from other countries are also welcome, subject to independent funding and availability of places. ------ Subject: Conference on Differential Equations & Computational Simulations From: "Zhu, Jianping" Date: Thu, 26 Apr 2007 16:45:25 -0500 Seventh Mississippi State - UAB Conference on DIFFERENTIAL EQUATIONS & COMPUTATIONAL SIMULATIONS November 1-3, 2007 Doubletree Hotel, Birmingham, AL Principal Speakers: OSCAR BRUNO, California Institute of Technology CHRIS COSNER, University of Miami JEFF CRANDALL, University of Virginia NORMAN DANCER, University of Sydney, Australia JOSHUA EPSTEIN, The Brookings Institution LISA FAUCI, Tulane University YANYAN LI, Rutgers University JEAN MAWHIN, University of Catholique de Louvain, Belgium CHARLES NIETUBICZ, Army research Laboratory STANLEY OSHER, University of California, Los Angeles JAIME PERAIRE, Massachusetts Institute of Technology JOHN RICE, IBM TJ Watson Research Center PETER TAKAC, University of Rostock, Germany This Interdisciplinary Conference will provide a joint forum where mathematicians, scientists, and engineers from academia and industry can exchange research ideas involving theoretical and applied developments in differential equations and computational simulations. In addition to the thirteen principal lectures, there will be sessions of contributed talks. Reviewed manuscripts will be published as a special issue of the Electronic Journal of Differential Equations. Pre-registration deadline is October 1, 2007.

Izhikevich" Date: Sun, 22 Apr 2007 00:55:15 -0700 Encyclopedia of Dynamical Systems, hosted by Scholarpedia - the free peer-reviewed encyclopedia, conducted election of authors for the article "Bifurcation" with the goal to identify the best living expert to invite to write such an article. The letter below was sent to John Guckenheimer from Cornell University, who won the election and already accepted the invitation. See http://www.scholarpedia.org/article/Bifurcation Eugene M. Izhikevich, Editor-in-chief of Scholarpedia, thanks all participants of the election. *** Dear Dr. Guckenheimer, As you might know, Scholarpedia, the free peer-reviewed encyclopedia, conducted election of authors for the article "Bifurcation" with the goal to identify the best living expert to invite to write such an article. The nominees (in the order of nomination by the public) were 1.Yuri A. Kuznetsov 2.Willy Govaerts 3.Eusebius Doedel 4.Philip Holmes 5.John Guckenheimer As the editor-in-chief, it is my great privilege to let you know that you were elected to write this article for Scholarpedia (http://www.scholarpedia.org). The election started on 12 May 2006 and ended today, engaging 112 participants. Rules of the election are described in http://scholarpedia.org/article/Scholarpedia:Election In summary, each participant can vote for no more than 3 candidates. Each vote is multiplied by the participant's Scholar Index, which reflects the expertise and usefulness of contributions of that person to Scholarpedia. (So that experts have greater weight in the election). Then, the weighted sum of the votes and a soft-max procedure is used to select the future author of the article. I am sending you a short explanation of this project and the instructions to reserve the article in a separate letter. Please, let me know whether you could write this article withing a reasonable period of time. ------ Subject: Post-doctoral position in Glaciology at University Joseph Fourier From: GAGLIARDINI Olivier Date: Mon, 23 Apr 2007 12:14:03 +0200 Isochrone geometry inversion in polar ice sheets Post-doctoral position at Joseph Fourier University, Grenoble, France.
