To accommodate the new Argos 500 MEG instrument [1] a general upgrade of the existing 2+1layer magnetically shielded room at the neurological department was necessary. Due to the innovative technology and the ambitious goal more stringent requirements where set for shielding performances and shielding anisotropy. The upgrade process of the existing MSR was carried out in cooperation with Advanc...

A bipartite graph is biplanar if the vertices can be placed on two parallel lines (layers) in the plane such that there are no edge crossings when edges are drawn straight. The 2-Layer Planarization problem asks if k edges can be deleted from a given graph G so that the remaining graph is biplanar. This problem is NP-complete, as is the 1Layer Planarization problem in which the permutation of t...

A key characteristic of work on deep learning and neural networks in general is that it relies on representations of the input that support generalization, robust inference, domain adaptation and other desirable functionalities. Much recent progress in the field has focused on efficient and effective methods for computing representations. In this paper, we propose an alternative method that is ...

Deep neural nets have caused a revolution in many classification tasks. A related ongoing revolution—also theoretically not understood—concerns their ability to serve as generative models for complicated types of data such as images and texts. These models are trained using ideas like variational autoencoders and Generative Adversarial Networks. We take a first cut at explaining the expressivit...
