I will report on recent work which proposes that the network dynamicsof the mammalian visual cortex are neither homogeneous nor synchronous buthighly structured and strongly shaped by temporally localized barrages ofexcitatory and inhibitory firing we call `multiple-firing events' (MFEs).Our proposal is based on careful study of a network of spi...

This talk is about a class of particle systems in which energyexchange among particles is mediated by 'the environment',symbolized by a lattice of rotating disks in mechanical modelsand 'energy tanks' in stochastic versions of these models.A number of years ago, J-P Eckmann and I studied models ofthis type. Taking for granted mathematical issues...

We present a geometric flow approach to the segmentation of two- three- dimensional shapesby minimizing a cost function similar to the ones used with geometric active contours or to the Chan-Vese approach. Our goal, well-adapted to many shape segmentation problems, including those arising from medical images, is to ensure that the evolving conto...

We present a series of applications of the Jacobi evolution equations alonggeodesics in groups of diffeomorphisms. We describe, in particular, how theycan be used to perform feasible gradient descent algorithms for imagematching, in several situations, and illustrate this with 2D and 3Dexperiments. We also discuss parallel translation in the gro...

Cassandra Yoo is the child of her Korean father and white, American mother and because of this, she has struggled to define her identity, never seeming to fit in with any one group. Her perception of her own race and ethnicity has changed throughout her academic career, influenced by her schoolmates, friends, family, and classes.

Classical optimal control problems for (ordinary, stochastic, or evolutionary partial) differential equations have the following feature: When an optimal control is found for a given initial time and initial state, the optimal control will remain optimal as time goes by along the optimal trajectory. This is called the time-consistency of the pro...

Economists have traditionally viewed futures prices as fully informative about future economic activity and asset prices. We argue that open interest could be more informative than futures prices in the presence of hedging demand and limited risk absorption capacity in futures markets. We find that movements in open interest are highly pro-cycli...

Interfacial effects are important in many cases for microscale transport. One of the few experimental techniques that can resolve interfacial transport with sub-micron spatial resolution is evanescent wave-based, or nano-, particle-image velocimetry (PIV), which determines fluid velocities over the first 500 nm next to the wall from the displace...
