The IMA is pleased to introduce the 20052007 postdocs and industrial postdocs. The new postdocs, who will arrive in September, are Evgeniy Bart (Weizmann Institute), SongHwa Kwon (Seoul National University), Hstau Liao (City University of New York), Alison Malcolm (Colorado School of Mines), Gloria Haro Ortega (Universitat Pompeu Fabra), Winston Ou (Purdue University ), Tatiana Soleski (Univeristy of Wisconsin–Milwaukee), and Carl Toews (MIT). The new industrial postdocs are Jungha An (University of Florida), who will be the fourth IMA industrial postdoc to work with Siemens, Kai Medville (Rutgers University), who will work with the Air Force Research Laboratory, and Xiaoqiang Wang (Pennsylvania State University), who will be the the VA Medical Center's third IMA industrial postdoc. These outstanding young researchers were selected from pools of seventytwo applicants for the regular postdoc positions and fiftynine industrial postdoc applicants.
The IMA 2005 Summer Program Wireless Communications, June 22July 1, is designed to meet the challenges posed by the rapid growth in the demand for multimedia wireless services such as voice, data, webbrowsing, video, and ecommerce in mobile telephony. Mathematical methods, including stochastic calculus, stochastic approximation, and stochastic control theory, have had a major impact on hybrid communication network models, asynchronous communication networks, CDMA systems, heavy traffic formulation, fluid models, etc. The program, which consists of a threeday tutorial followed by a fiveday workshop, will focus on the interplay of the physical, link, and network layers in wireless networks. The objective is to facilitate communication between academia and the industry, and to bridge the mathematical sciences, engineering, and operations research communities.
The Special Workshop MixedInteger Programming, July 2529, will bring together many of the leading researchers in both the theoretical and computational aspects of mixedinteger programming (MIP) to highlight recent advances, foster interaction and collaboration, and to discuss the expansion of the role of MIP in several potential highimpact application areas, such as network design for the Power Grid, computational biology, medical treatment planning, and cryptography. MIP constitutes a unique computational science: it routinely attempts to solve fundamentally intractable problems arising from many applications, and it does so by blending mathematics, ever more sophisticated implementations, and innovative modeling. This workshop is supported in part by the Mathematical Sciences Department of IBM Research and SAS Operations Research & Management Science.
Mathematical Modeling in Industry—A Workshop for Graduate Students, August 110, will provide graduate students and qualified advanced undergraduates with first hand experience in industrial research. Students will work in six teams of up to seven students under the guidance of a mentor from industry. The mentor will help guide the students in the modeling process, analysis and computational work associated with a realworld industrial problem. Each team will make a midprogram progress report and an final presentation, and submit a written final report. The deadline for applications for the Mathematical Modeling in Industry workshop is April 15.
The meeting New Directions in Probability Theory, August 56, is cosponsored by the Institute of Mathematical Statistics and the IMA. The meeting, which will be held at the IMA and immediately precedes the Joint Statistical Meetings, August 711, is intended for a general probability audience interested in recent developments in probability theory. The topics of the sessions are flows and random media; probability, combinatorics, and statistical mechanics; stochastic integration; stochastic partial differential equations; and random walk in random environments.
The School of Mathematics, University of Minnesota, will host the eighth RiviéreFabes Symposium on Analysis and PDE April 810, 2005.

Paolo Biscari (Politecnico di Milano)  Telephonecord instabilities in thin smectic capillaries 
Abstract: Telephonecord patterns have been recently observed in smectic liquid crystal capillaries. In this talk we analyse the effects that may induce them. As long as the capillary keeps its linear shape, we show that a nonzero chiral cholesteric pitch favors the SmA*SmC* transition. However, neither the cholesteric pitch nor the presence of an intrinsic bending stress are able to give rise to a curved capillary shape. The key ingredient for the telephonecord instability is spontaneous polarization. The free energy minimizer of a spontaneously polarized SmA* is attained on a planar capillary, characterized by a nonzero curvature. More interestingly, in the SmC* phase the combined effect of the molecular tilt and the spontaneous polarization pushes towards a helicoidal capillary shape, with nonzero curvature and torsion.  
Ken A. Dill (University of California  San Francisco)  Protein folding: A problem in global optimization 
Abstract: Joint work with Banu Ozkan, John Chodera, and Thomas Weikl. To compute the folded structure of a protein using a physical model and the monomer sequence has been regarded as a challenge because it involves multiple time and space scales. Our approach has been to understand how proteins physically fold and to try to apply that strategy to protein structure prediction. We believe that proteins break their large global optimization problem into smaller local optimizations. We have been exploring various methods for exploiting that idea for protein structure prediction.  
Weinan E (Princeton University)  CauchyBorn rule, generalized CauchyBorn rule and applications to nanomechanics 
Abstract: The focus of this talk is to develop continuum mechanics type of models for studying the deformation of nanoscale objects such as nanotubes, nanorods and DNA. The basic tool we will use is various generalizations of the classical CauchyBorn rule. For this purpose, we will first review the classical CauchyBorn rule for bulk crystals. We will discuss the validity of the CauchyBorn rule and give a precise characterization of its boundary of invalidity. We then discuss the generalization of the CauchyBorn rule to curved low dimensional objects, including the local CauchyBorn rule and the exponential CauchyBorn rule. Finally we turn our attention to nanotubes and nanorods, and examine whether their deformation can be described by these continuum theories.  
Ron Elber (Cornell University)  Computing timescales by milestoning 
Abstract: An algorithm is presented to compute time scales of complex processes following predetermined milestones along a reaction coordinate. A nonMarkovian hopping mechanism is assumed and constructed from underlying microscopic dynamics. General analytical analysis, a pedagogical example, and numerical solutions of the non Markovian model are presented. No assumption is made in the theoretical derivation on the type of microscopic dynamics along the reaction coordinate. However, the detailed calculations are for Brownian dynamics in which the velocities are uncorrelated in time (but spatial memory remains).  
Ryan S. Elliott (University of Michigan)  Stability and bifurcation of multilattice crystals undergoing martensitic transformation 
Abstract: Understanding thermoelastic martensitic transformations is a fundamental component in the study of shape memory alloys. These transformations involve a hysteretic change in stability of the crystal lattice between an austenite (high symmetry) phase and a martensite (low symmetry) phase within a small temperature range. To study these transformations, a set of phenomenological temperaturedependent atomic pairpotentials is used to derive the crystal's energy density W(F,S_1,S_2,...;T) as a function of a uniform deformation F and a set of internal atomic shift degrees of freedom S_i. Special attention is paid to the evaluation of crystal structure stability. Using a specific set of temperaturedependent pairpotentials a stressfree bifurcation diagram is generated for the B2 binary crystal structure (with temperature serving as the loading parameter). A hysteretic transformation is suggested by the existence of certain stable equilibrium branches corresponding to B2 (CsCl) and B19 (orthorhombic) crystal structures. These results indicate the ability of temperaturedependent atomic potential models to provide valuable insight into the behavior of shape memory alloys such as NiTi, AuCd, and CuAlNi.  
Kevin Ellwood (Ford Motor Company)  A Model for the Oxidative Aging of Tires 
Abstract: A simple kinetic model has been developed to interpret issues related to accelerated aging of tires. The finiteelement model is based on the Basic Autoxidation Scheme and incorporates mass transport limitations related to diffusion of oxygen into the layered elastomer system. The effect of aging on transport properties, such as diffusivity, due to changes in crosslink density is also considered in the model. The extent of oxidation is calculated at different locations within the tire as functions of time, temperature, and inflation media. Approximate changes to physical properties were derived from oxidation histories predicted by the model and compared to experimentally measured data which includes crosslink density and elongationtobreak. Finally, we will examine the effect of temperature on accelerated ageing in the context of accelerated testing.  
Jim Evans (Iowa State University)  From atomic scale ordering to mesoscale spatial patterns in surface reactions: Heterogeneous coupled LatticeGas (HCLG) simulation approach 
Abstract: Homoepitaxial thin film growth produces a rich variety of farfromequilibrium morphologies. Atomistic latticegas models analyzed by KMC simulation have been most successful to date in predicting behavior observed in specific experiments. However, 2D continuum formulations (levelset, phasefield, geometrybasedsimulation = GBS) retaining discrete layers have been explored as alternatives, especially for the regime of highly reversible island formation where KMC becomes inefficient. Exploiting GBS, we present the first precise results for the submonolayer island size distribution in this regime [1]. 3D continuum formulations have been applied to describe multilayer kinetic roughening where step edge barriers inhibit downward transport and produce unstable growth (mound formation). We analyze this phenomonon using realistic atomistic modeling to show that Ag/Ag(100) [regarded as the prototype for smooth growth] actually grows very rough [2]. Furthermore, mound dynamics is seen to be more complex than predicted by standard 3D continuum models. [1] PRB 68 (03) 121401; SIAM MMS 3 (05); [2] PRB 65 (02) 193407.  
Matthias Kurzke (University of Minnesota)  Boundary vortices in thin magnetic films 
Abstract: We analyze a model for thin ferromagnetic films that leads to the formation of vortices at the boundary. The energy asymptotically splits into a singular part depending only on the number of vortices and a finite part depending on their position. This finite part, the renormalized energy, is shown to also control the gradient flow motion associated to the boundary vortex functional. The results and proofs are similar to the theory for GinzburgLandau vortices by BethuelBrezisHelein for the static and SandierSerfaty for the dynamic case.  
Frederic Legoll (University of Minnesota)  Analysis of a prototypical multiscale method coupling atomistic and continuum mechanics 
Abstract: In order to describe a solid which deforms smoothly in some region, but non smoothly in some other region, many multiscale methods have been recently proposed, that aim at coupling an atomistic model (discrete mechanics) with a macroscopic model (continuum mechanics). We present here a theoretical analysis for such a coupling in a onedimensional setting. We study both the general case of a convex energy and a specific example of a nonconvex energy, the LennardJones case. In the latter situation, we prove that the discretization needs to account in an adequate way for the coexistence of a discrete model and a continuous one. Otherwise, spurious discretization effects may appear. We also consider the effect of the finite element discretization of the continuum model on the behaviour of the coupled model. This work is joint with Xavier Blanc (Paris 6) and Claude Le Bris (CERMICS, ENPC).  
Alexander Mielke (WIAS  Berlin)  Macroscopic equations for microscopic dynamics in periodic crystals 
Abstract: In infinite periodic lattices the solutions can be studied by Fourier analysis on the associated dual torus. However, in doing a limit procedure with vanishing atomic distance, one observes new phenoma which are usually studied by WKB mehtods. We show that similar results can be obtained under much weaker assumptions by using weak convergence methods. First we show that linearized elastodynamics can be obtained by a gamma limit procedure which automatically produces the effective elastic tensor. Second we study the transport of energy in the lattice which occurs on quite different wave speeds as the macroscopic elastic waves. It is possible to derive a energy transport equation for a Wigner measure which depends on time, space and the wave vector on the dual torus.  
Julie C. Mitchell (University of Wisconsin)  Computer Prediction of Protein Docking and Analysis of Binding Interfaces 
Abstract: Recent work on the development of methods for protein docking and analysis of binding interfaces will be discussed. One of the methods presented is the Docking Mesh Evaluator that uses an implicit solvent model for electrostatics. The Docking Mesh Evaluator is capable of exhaustive search as well as of local and global optimization of binding energies, all of which can be performed using parallel computation. The Fast Atomic Density Evaluator is a method for analyzing protein shape, and shape complementarity within binding interfaces. The Fast Atomic Density Evaluator's complementarity "hot spots" correlate with residues in which mutation is known to impact binding. This has recently been used in the development of engineered ribonucleases able to kill cancer cells. Shape complementarity analysis can also aid docking prediction, either as a postfilter for exhaustive search results or as a means of dynamic parameterization for flexible docking calculations.  
Anja Riegert (Max Planck Institute for the Physics of Complex Sys)  Modeling fast Hamiltonian chaos by suitable stochastic processes 
Abstract: Projection operator techniques known from nonequilibrium statistical mechanics are applied to eliminate fast chaotic degrees of freedom in a lowdimensional Hamiltonian system. A perturbative approach, involving a Markov approximation, yields a FokkerPlanck equation in the slow subspace which respects the conservation of energy. A numerical and analytical analysis of suitable model systems demonstrates the feasibility of obtaining the system specific drift and diffusion terms and the accuracy of the stochastic approximation on all time scales. NonMarkovian and nonGaussian features of the fast variables are negligible.  
Miroslav Trajkovic (Symbol Technologies)  Industrial applications of scene change detection algorithms 
Abstract: In this presentation I am going to discuss different approaches to scene change detection and its various industrial applications. I will give several examples of different scene change detection algorithms I developed including: motion detection from a moving camera, with application to video surveillance; building background model in the presence of moving objects; detection of the foreground objects with fixed background, and it’s application in automotive industry; and illumination invariant motion detection based on frame differencing; and its application in the bar code reading industry.  
Curtis R. Vogel (Montana State University)  Estimation and Control in Adaptive Optics for Extremely Large Telescopes 
Abstract: Adaptive optics (AO) refers to the realtime correction of wavefront aberrations in an optical imaging system. AO has important applications which range from retinal imaging to highspeed laser communications to astronomy. In astronomical AO, wavefront aberrations are caused by density variations due to differential heating of the air, combined with turbulent mixing. These aberrations are indirectly measured with wavefront sensors and corrected with one or more deformable mirrors. Wavefront reconstruction refers to the control algorithms which map sensor measurements to actuator commands that shape the deformable mirror(s). In this talk we will present an overview of astronomical AO, with an emphasis on wavefront reconstruction. In particular, we will address an interesting limited angle tomography problem, known as atmospheric turbulence tomography, which arises in a particular flavor of AO called multiconjugate adaptive optics.  
Giovanni Zanzotto (University of Padua)  Stressed microstructures in M9RM18R martensites 
Abstract: Joint work with Xavier Balandraud (Laboratoire de Mécanique et Ingénieries (LaMI), Institut Français de Mécanique Avancée (IFMA), Université Blaise Pascal (UBP). We revisit the phase transformation that produces monoclinic 'longperiod stacking' M9R or M18R martensites in Cubased shapememory alloys, and analyze some associated microstructures, in particular a typical wedgeshaped configuration (Fig.). The basic premise is that the cubictomonoclinic martensitic phase change in such alloys is, geometrically, a slight modification of the wellknown bccto9R transformation occurring for instance in Li and Na, whose basic strain, at the micro level, is the same Bain strain as for the bcctofcc transition. One then determines the 'nearBain' microstrain variants pertaining to these elements and alloys, and analyze the longperiod stacking martensite as a mesoscale 'adaptive phase.' Twins, habit planes, and also more complex microstructures, such as the CuZnAl wedge, can be analyzed in this way. Earlier conclusions that this microstructure is not kinematically compatible at zero stress are confirmed. However, one can check the wedge is `close enough' to compatibility and compute the corresponding stresses, which turn out to be low, causing only minimal plastification and damage in the crystal. This microstructure is therefore rationalized as a viable path for the transformation also in these alloys. One can moreover verify this to be true for all the known lattice parameters reported for materials exhibiting longperiod M9RM18R martensites. The general conclusion is that the observed martensitic microstructures can be stressed to various degrees also in good memory alloys; and that there seem to be no need for material tuning in order tgat such stresses be low. Indeed, the latticeparameter relations, guaranteeing the zerostress compatibility of special configurations, favoring the transformation and its reversibility, do not need to be strictly enforced because microstructural stresses are not very sensitive to lattice parameter values.
