A family $${\mathcal {F}}$$ on ground set $$[n]:=\{1,2,\ldots , n\}$$ is maximal k-wise intersecting if every collection of at most k sets in has non-empty intersection, and no other can be added to while maintaining this property. In 1974, Erdős Kleitman asked for the minimum size a family. We answer their question $$k=3$$ sufficiently large n. show that unique obtained by partitioning [n] int...

In this paper, we propose a novel pixel-wise visual object tracking framework that can track any anonymous object in a noisy background. The framework consists of two submodels, a global attention model and a local segmentation model. The global model generates a region of interests (ROI) that the object may lie in the new frame based on the past object segmentation maps; while the local model ...

The paper reviews the Astro-WISE infrastructure and demonstrates that the Astro-WISE Information System provides a Grid itself. We describe the integration of Astro-WISE with an external Grid infrastructure (BiGGrid). The integration is performed on all infrastructural layers (data storage, metadata and processing layers) with Astro-WISE as a “master” infrastructure. We report the use of the in...

Transcatheter valve aortic implantation (TAVI) is undoubtedly one of the most notable advances in the treatment of heart disease. Its results have been repeatedly confirmed in randomized trials comparing TAVI with conventional surgical aortic valve replacement and in registries, in patients with varying degrees of surgical risk (moderate, high, very high or prohibitive), and it will presumably ...
