##### Demixing Sines and Spikes: Spectral Super-resolution in the Presence of Outliers

In this talk we consider the problem of super-resolving the line spectrum of a multisinusoidal signal from a finite number of samples, some of which may be completely corrupted. Measurements of this form can be modeled as an additive mixture of a sinusoidal and a sparse component.

##### A random walk on the upper triangular matrices

We study the following random walk on the group of n n upper triangular matrices with coecients in Z=pZ and ones along the diagonal. Starting at the identity, at each step we choose a row at random and either add it to or subtract it from the row immediately above.

##### Algorithms for Reducing the Computational Burden of cryo-EM

**Please note different day and location (Thursday, McDonnell 102A).** Computational expense has long been a challenge for 3D structure determination in electron cryomicroscopy (cryo-EM). This problem has become more pressing as resolutions have increased and the desire to separate
