The Serre-Green-Naghdi (SGN) equations, also known as the fully nonlinear Boussinesq wave equations, are known to accurately describe a wide range of waves and in particular shoaling waves for which dispersive effects cannot be neglected. I will show how this model can be solved in a simple way using the combination of a robust, well-balanced ex...

Neurons of the higher brain immediately undergo spreading depolarization (SD) in response to ischemia resulting from heart failure, traumatic brain injury or focal stroke. The current(s) driving SD remain unidentified. At SD onset, neurons cease firing, swell and can die within minutes. To account for the massive SD current, the channel has to b...

On April 19, 1943, the destruction of the Warsaw Ghetto began. The remaining Jewish population, depleted by transports to the death camp at Treblinka, was exterminated. Units of SS stormed the Ghetto under the command of General Stroop. Unexpectedly, Jewish resistance was strong, and it took more than a month for the Germans to subdue the Warsaw...

If A is a finite-dimensional algebra with automorphism group G, then varieties of generating r-tuples of elements in A, considered up to G-action, produce a sequence of varieties B(r) approximating the classifying space BG. I will explain how this construction generalizes certain well-known examples such as Grassmannians and configuration spaces...

In an approach similar to Ewald's method for evaluating lattice sums, we split the application of Helmholtz Green's functions between the spatial and the Fourier domains and, for any finite accuracy, approximate their kernels.In the spatial domain we use a near optimal linear combination of decaying Gaussians with positive coefficients and, in t...

The Steiner polynomial of a solid body in R^d is of degree d and describes the volume as a function of the thickening parameter (parallel body). There are d+1 coefficients which are used to define the d+1 intrinsic volumes of the solid body. In d=2 dimensions, the first intrinsic volume is the length, and in d=3 dimensions, it is the total mean ...

The inverse photolithography problem is a key step in the production of integrated circuits. I propose a regularization and computation strategy for this optimization problem, whose key feature is a regularization procedure for a suitable thresholding operation. The validity of the method is shown by a convergence analysis and by numerical exper...

We present an approximation algorithm for network revenue management problems. In our approximation algorithm, we construct an approximate policy using value function approximations that are expressed as linear combinations of basis functions. We use a backward recursion to compute the coefficients of the basis functions in the linear combinatio...

We consider solving for a single component of the solution to a system of linear equations, Ax = b, where A is an n-by-n real-valued matrix, and b is a real-valued n dimensional vector. This equation can equivalently be written as x = Gx + z for an appropriate choice of G and z. We are interested in utilizing the sparsity of G (equivalently of A...

For discretizations of partial differential equations, the standard methods for numerically solving Lyapunov and Riccati equations (as for example implemented in matlab) are usually not suitable since the computational effort and storage requirements are too high.

Duplex DNA, the genetic material in living cells, is an unusually inflexible biopolymer. The persistence length of duplex DNA corresponds to 150 base pairs under physiological conditions. Surprisingly, the physical origin of this DNA stiffness is unknown. In particular, the contribution of the high negative charge density of DNA to its stiffness...

Recently we introduced a framework for applying subgradient methods to solve general convex, conic optimization problems. The framework, once seen, is 'obvious,' but had not appeared in the literature, a blind spot. Quite recently we posted a refinement of the framework in the special case of hyperbolic programming. Hyperbolicity cones have alge...
