Using a combinationof numerical Evans function computations and asymptotic ODE analysis,we carry out global stability analyses for interesting examples including ideal gas and parallel MHD shocks, across the entire rangeof physical parameters: in particular, in the large amplitude ormagnetic field limit.

We discuss finally stability and bifurcation of flow in a channel with periodic boundary conditions: cellular bifurcation, pattern formation,and an Evans function construction for genuinely multi-dimensional(i.e., nonplanar) solutions.

Determining the identities and frequencies of species present in a sample is a central problem in metagenomics, with scientific, environmental and clinical implications.A popular approach to the problem is sequencing the Ribosomal 16s RNA gene in the sample using universal primers, and using variation in the gene's sequence between different spe...

The talk will begin with a definition of RNA secondary structure,including three different ways to display these structures. Two distinctapproaches will be presented for determining secondary structure fromsequence data. The comparative method requires a multiple sequencealignment of a collection of homologous RNA sequences. It uses phylogenyto ...

The representation of color for perception differs from therepresentation for displays. We consider the map from (r,g,b)-space to (Intensity, hue, saturation)-space, and show how this non-linear space is useful for sensingdevices.

Conformational changes in proteins are intrinsic to almost every function, but sampling such changes remains one of the most difficult bio-computational problems. The challenge lies on two levels. First, algorithms which can efficiently focus computer time on the correct path ensemble are necessary. Second, even if perfect path-sampling algorith...

In this lecture we shall present a survey of recent work on several topics related with numerical approximation of waves.Control Theory is by now and old subject, ubiquitous in many areas of Science and Technology. There is a quite well-established finite-dimensional theory and many progresses have been done also in the context of PDE (Partial D...

Distance weighted discrimination (DWD) is a margin-based classifier with an interesting geometric motivation. DWD was originally proposed as a superior alternative to the support vector machine (SVM), however DWD is yet to be popular compared with the SVM. The main reasons are twofold. First, the state-of-the-art algorithm for solving DWD is...

Convolutional neural networks (CNN’s) are widely used in deep learning. The Lipschitz bound is important in the study of stability of CNN’s and computation of the Lipschitz bound is needed for generative networks. We give a general framework for CNN’s and prove that the Lipschitz bound of a CNN can be determined by solving a linear program...

Vesicles are locally-inextensible fluid membranes that cansustain bending. We consider the dynamics of flows ofvesicles suspended in Stokesian fluids. We use a boundaryintegral formulation for the fluid that results in a set ofnonlinear integro-differential equations for the vesicle dynamics.The motion of the vesicles is determined by balancingt...

We introduce the TUBE connection for domains with finite perimeters; Then a metricand we characterise the necessary condition forthe geodesic tube. We obtain a complete metricspace of Shapes with non prescribed toplogy.That metric extends the Courant metricdeveloped in the book Shape and Geometry(Delfour and Z) , SIAM 2001.

A fundamental application for optimal control of physical flows on networks is the operation of large-scale natural gas transmission pipelines. A control system model has been developed for the distributed dynamics of compressible gas flow through large-scale pipeline networks with time-varying injections, withdrawals, and control actions of com...

RNA 3D structure files contain essentially complete information about the interactions that form the 3D structure of an RNA molecule for a given organism. Homologous molecules in other organisms will have very similar 3D structures, but we expect to see sequence variability due to structurally neutral base substitutions, insertions, and deletion...
