A dynamic sensor network may be represented as a sequence of simplicial complexes, and analyzed using zigzag persistent homology, with the resulting barcode containing birth-death intervals for homological features of the sequence. In this talk I will first describe the relationship between these intervals and the time-varying coverage holes in ...

We discuss a set up for the Boltzmann - Poisson system for full electronic bands with a variety of boundary condition, including the effect of roughness. We present a a detailed numerical by means of DG schemes study of specular vs diffusive reflection conditions for a two dimensional domain with transport in full phase $k$-space (work in collab...

We discuss a numerical approach an inverse problem strategy associated to the Boltzmann-Poisson system of equations for transport of electrons in the reconstruction of space inhomogeneities for the background function associated to total charges. The objective of the (ill-posed) inverse problem is to recover the shape of distributions of ions or...

We will discuss a deterministic approximation for charged transport model of Boltzmann Poisson type along electronic bands. This is a kinetic model of hot electron flow in a graph given by computed energy bands and the scattering mechanisms for the collisional structure such as Fermi's golden rule for symmetric bands or full scattering forms for...

Queueing systems exhibit a fundamental tradeoff between the availability of resources and performance, such as delays and queue lengths. Typically such resources include the number and the speed of servers, but other resources, for example, the availability of a common buffer and the amount of information exchange, can also have a first order im...

Neural networks have surpassed the performance of virtually any traditional computer vision algorithm thanks to their ability to learn priors directly from the data. The common and relatively simple encoder/decoder architecture, for instance, has pushed the state-of-the-art of a number of tasks, from optical flow estimation, to image deblurring,...

The crocodilia have multiple interesting characteristics thataffect their population dynamics. They are among severalreptile species which exhibit temperature-dependent sexdetermination (TSD) in which the temperature of eggincubation determines the sex of the hatchlings. Their lifeparameters, specifically birth and death rates, exhibitstrong age...
