The current talk is concerned with traveling wave solutions of reaction diffusion equations in random media.I will first introduce the concept of random traveling wave solutions and present a general theorem about theexistence of such traveling wave solutions. I will then discuss the existence, uniqueness, and stability of random traveling wave ...

In this talk, traveling waves for nonlocal evolution systems with bistable nonlinearity are discussed. The spectrum of the operator obtained by linearizing about such a traveling wave are also examined.

I will describe several works dealing with the construction of different solutions on lattices. I will first investigate the problem of pulsating trvaelling waves known as travelling breathers. I will secondly deal with qusi-periodic motions on the lattice via a KAM theorem. I will construct finite dimensional and infinite dimensional invariant ...

While the theory of nonlinear waves in partial differential equations is very well developed, understanding travelling waves in systems posed on lattices is challenging, and many basic questions remain open. Indeed, travelling waves on lattices can be found only by solving functional differential equations of mixed mode, which are ill-posed as i...

We present results for an advection-reaction-diffusion model describing malignant tumour (i.e. skin cancer) invasion. Numerical solutions indicate that both smooth and shock-fronted travelling wave solutions exist for this model. We verify the existence of both type of these solutions using techniques from geometric singular perturbation theory ...

We will consider the inverse problem of determining the sound speed or index of refraction of a medium by measuring the travel times of waves going through the medium. This problem arises in global seismology in an attempt to determine the inner structure of the Earth by measuring travel times of earthquakes. It has also several applications in ...

In inverse boundary problems one attempts to determine the properties of amedium by making measurements at the boundary of the medium. In thelecture we will concentrate on two inverse boundary problems, ElectricalImpedance Tomography and Travel Tomography in anisotropic media. Theseproblems arise in medical imaging, geophysics and other fields. ...

In practice of medicine, multiple treatments are often available to treat individual patients. The task of identifying the best treatment for a specific patient is very challenging due to patient inhomogeneity. Multi-armed bandit with covariates provides a framework for designing effective treatment allocation rules in a way that integrates the ...

Two pencil drawings on one sheet, divided by a horizontal pencil slash. The upper drawing depicts a detail of spindly tree roots, with labels noting "on bank" and "current", with an arrow pointing left, indicating the direction of water current. The lower drawing portrays the base of an elm tree, with spreading roots.
Pencil drawing of a landscape, framed by a rectangular pencil border. A second rectangle in pencil, with the same dimensions as the larger border, overlays the center of the scene. Leafy trees in hilly foreground and middle ground, opening onto distant hills. Likely a study for a taxidermy diorama background, depicting a scene from Panama as enc...
