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 ...

Aspect-Oriented Programming (AOP) is a paradigm that allows the addition of new functionality to an existing system in a clean and modular fashion. In this research we utilize AOP to define support for the software development process within a development environment (Eclipse). AspectJ aspects that ...

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. ...
