The DataNet Federation Consortium uses a policy-based data management system to apply and enforce preservation requirements. This paper describes the Preservation Policy Toolkit developed by the consortium. In particular, the paper describes the infrastructure needed for preservation, presents examples of computer actionable forms of policies, and provides a generic template for designing actio...

The Symmetric Positive Definite (SPD) matrices have received wide attention for data representation in many scientific areas. Although there are different attempts to develop effective deep architectures processing on the Riemannian manifold of SPD matrices, very few solutions explicitly mine local geometrical information feature representations. Given great success mechanisms Euclidean methods...

An accepted digital preservation workflow is emerging in which file formats are identified and those believed to be at risk are migrated to what are perceived to be less risky formats. This raises important questions about what to convert and when, if at all. In other words, how to connect file identification and migration. This area has become known as preservation planning, and seeks to take ...

Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and 2012 Indian Ocean earthquake sequences. In conventional Mohr-Coulomb failure theory, orthogonal faulting requires a zero frictional coefficient (pressure-insensitive), which is unlikely in brittle lithosphere. The simulations developed here show that faults can form layer i...

many food products are perishable by nature and require protection from spoilage during their preparation, storage and distribution to give them desired shelf-life. because food products are now often sold in areas of the world far distant from their production sites, the need for extended safe shelf-life for these products has also expanded. currently, there is a strong debate about the safety...

Photosynthesis relies on energy transfer from light-harvesting complexes to reaction centers. Phycobilisomes, the light-harvesting antennas in cyanobacteria and red algae, attach to the membrane via the multidomain core-membrane linker, L(CM). The chromophore domain of L(CM) forms a bottleneck for funneling the harvested energy either productively to reaction centers or, in case of light overlo...
