Many US libraries subscribe only to the American version, but tell your librarian ZentralblattMATH is a little bit better because it considers applied math to be math so it finds more publications. Every search of ZentralblattMATH produces a list of pubs and a list of authors ranked by numbers of pubs. I am using that feature here. There have been 21 titles for SIAM journals of which 16 are currently in use. I am ignoring the one, translated journal. The 21 titles beginning with the venerable J. SIAM in 1952 have published 34,234 articles by 45,907 authors. SIAM may have a different count because for example it is not clear whether a book review is an article and it is an art to identify unique people from names. Who has the most SIAM articles? I planned to list only the top 10 but to keep peace in Boulder I thought it wise to list a few more. They are: Manteuffel, Thomas A. (73), Matkowsky, Bernard J. (69), Chan, Tony (68), Kunisch, Karl (63), Golub, Gene H. (62), Saad, Yousef (56), Keller, Joseph B. (56), Tarjan, Robert E. (55), Kushner, Harold J. (55), Higham, Nicholas J. (55), McCormick, Stephen F. (52), Ito, Kazufumi (52), and Babuška, Ivo M. (52). ------------------------------------------------------- From: Dan Stefanica [log in to unmask] Date: October 23, 2014 Subject: New Book, A Linear Algebra Primer for Financial Engineering The book covers numerical linear algebra methods for financial engineering applications.

The author combines three pillars of optimization — theoretical and algorithmic foundation, familiarity with various applications, and the ability to apply the theory and algorithms on actual problems — and rigorously and gradually builds the connection between theory, algorithms, applications, and implementation. Readers will find more than 170 theoretical, algorithmic, and numerical exercises that deepen and enhance the reader's understanding of the topics. The author includes several subjects not typically found in optimization books—for example, optimality conditions in sparsity-constrained optimization, hidden convexity, and total least squares.

The position is affiliated with the project High- Definition Tomography (www2.compute.dtu.dk/~pcha/HDtomo) financed by the European Research Council. The title of the PostDoc project is “Formulation and Application of Priors in Spectral CT.” We will develop new robust and efficient computational methods for spectral CT, where the reconstruction model must include information about the absorption’s energy dependence. The main challenge is to formulate and incorporate prior information about the spectral behavior into the reconstruction algorithm, in order to ensure a reliable reconstruction. This involves careful considerations of the formulation and parameterization of the forward model and the spectral information, how to apply compressed sensing techniques (sparsity), and how to represent large spectral 3D solutions. We will also develop efficient implementations of the methods and test them on real data, e.g., from CT scanners at DTU. Preference will be given to candidates that have documented research experience in Scientific Computing and Applied Mathematics. A background in Optimization and Inverse Problems is especially relevant.

The position is affiliated with the project High-Definition Tomography (www2.compute.dtu.dk/~pcha/HDtomo) financed by the European Research Council. The title of the PhD project is “Priors for Temporal Tomographic Image Reconstruction.” We will develop large-scale computational reconstruction methods for tomography where the temporal evolution of the object must be incorporated in the reconstruction model. To do this we must formulate and develop reconstruction models that incorporate prior information about the dynamics of the object. The emphasis of the project is on the mathematical and computational aspects, preferably guided by applications in materials science, and possibly using spectral CT and techniques from compressed sensing (sparsity). The goal is to arrive at novel algorithms that perform better than existing methods due to the inclusion of strong priors for in the reconstruction model. Candidates must have a master degree in applied mathematics or equivalent academic qualifications. Preference will be given to candidates who have a strong background in numerical computations, and must have experience with computational methods for optimization and differential equations. Applications must be submitted ONLINE in English as one single PDF via DTU’s home page: www.dtu.dk/english/career/job?id=7a110569-1ccc-43f7-a1a5- a38fa6306f2b For more information please contact Prof. Per Christian Hansen, [log in to unmask] or Assistant Prof. Martin S.
