A new form of coherent optical microscopy is described thatgenerates images (reconstructions) of two and three-dimensional,penetrable scatteringobjects computationally from sets of measured digital hologramsof scattered field data collected in a suite of scatteringexperiments. Themicroscope uses the technique of 'phase shifting holography'(expla...

Photonic crystals and Metamaterials are made from assemblies of multiple elements usually arranged in repeating patterns at scales of the order or smaller than the wavelengths of the phenomena they influence. Because time and space play a similar role in wave propagation, wave propagation is affected by spatial modulation or by time modulation o...

After separating the electronic end nuclear coordinates through the Born-Oppenheimer approximation, one may attempt to solve the electronic Schrodinger equation by a hierarchy of wave function techniques. The lowest level in this hierarchy and the core method of the wave function quantum chemistry is the Hartree-Fock (HF) model, in which each el...

Measured bioresponses are often characterized byan intrinsic high frequency and strong persistent correlationsinhibiting statistical modeling by the traditional techniques.The talk overviews two novel wavelet-based techniquesfor modeling such challenging data.Wavelet domains provide natural modelingenvironments for data that scale, as well as fo...

We analyze long range wave propagation in three-dimensional randomwaveguides. The waves are trapped by top and bottom boundaries, butthe medium is unbounded in the two remaining directions. We considerscalar waves, and motivated by applications in underwater acoustics,we take a pressure release boundary condition at the top surface anda rigid bo...

Wave propagation in optical lattices with honeycomb background, termed Photonic Graphene, is investigated. A tight binding approximation leads to a coupled mode system. In bulk media a nonlinear Dirac type system is obtained which describes conical, elliptical and straight-line diffraction. With rapidly varying helical waveguides linear and nonl...

In this talk, we shall survey some recent results on the wave propagation inthe two species competition systems with Lotka-Volterra type nonlinearity. This includes systems with continuous and discrete diffusion.Both monostable and bistable cases shall be discussed.Questions on minimal wave speed for the monostable case,propagation failure in th...

We study wave motion in a lattice differential equation, specifically, in a spatially discrete Allen-Cahn equation with a bistable nonlinearity. The system may, but need not, be near the continuum limit. Superimposed on the regular (periodic) lattice is a spatial variation which varies in an arbitrary (generally non-periodic) fashion; it can eit...

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...

Phytoplankton floating in the ocean, sperm moving through the reproductive tract, and fish swimming in the sea all rely on an intricate interplay of forces. These are examples of how flexible structures interact with a surrounding fluid €“ a common theme in biological fluid dynamics. This lecture will explore how mathematical models and computat...

In center of field is a heart within which is an Akan stool on which are placed 2 fleur de lis and a Maltese cross in the center. Radiating out from the center are ten hearts, each with the name of a Ghanaian town, either located along the coast or inland as far as Kumasi. Color: yellow, tangerine, and indigo.
