We examine the proof-theoretic strength of parameterized tree-like resolution---a proof system for the $\co\W[2]$-complete set of parameterized tautologies. Parameterized resolution and, moreover, a general framework for parameterized proof complexity was introduced by Dantchev, Martin, and Szeider (FOCS'07). In that paper, Dantchev et al.\ show a ...

In this talk I will describe the algorithms and mechanisms underlying a distributed system for genetic linkage analysis, called Superlink-online. It is a production online system which serves hundreds of geneticists worldwide allowing for faster analysis of genetic data via automatic parallelization and execution on ...

Metagenomics is a new field in which genetic material is extracted directly from the environment and is subsequently analyzed by a variety of biological and computational methods. Metagenomics makes it possible to study microbial communities directly from the environment and also to study microbial species ...

Geometric rearrangement of images includes operations such as image retargeting, object removal, or object rearrangement. Each such operation can be characterized by a shift-map: the relative shift of every pixel in the output image from its source in an input image. We describe a new ...

Fluorescence microscopy is a powerful tool in biology and biomedical sciences. Microscopic specimens usually yield fluorescence intensity images that are dim and thus suffer from low signal-to-noise ratio (SNR). Moreover, in multispectral imaging of fluorescing specimen, intensities are just a means to obtain information about ...

The images acquired via medical imaging modalities are frequently subject to low signal-to-noise ratio, bias field and partial volume effects. These artifacts, together with the naturally low contrast between image intensities of some neighboring structures, make the extraction of regions of interest (ROIs) in clinical ...

We will discuss two important conjectures in additive combinatorics. The first one is the polynomial Freiman-Rusza conjecture, which relates to the structure of sets with small doubling. The second is the inverse Gowers conjecture for $U^3$, which relates to functions which locally look like quadratics. ...
