Frontiers in Aging Neuroscience, 2016 Tau is a microtubule-associated protein that plays an important role in axonal stabilization, neuronal development, and neuronal polarity. In this review, we focus on the primary, secondary, tertiary, and quaternary tau structures. We describe the structure of tau from its specific residues until its conformation in dimers, oligomers, and larger ...

Discrete structures in gravity [PDF]
, 2000 Discrete approaches to gravity, both classical and quantum, are reviewed briefly, with emphasis on the method using piecewise-linear spaces. Models of 3-dimensional quantum gravity involving 6j-symbols are then described, and progress in generalising ...

Structures and Structural Realism [PDF]
Logic Journal of the IGPL, 2005 Summary: The `ontic' form of structural realism (OSR), roughly speaking, admits a complete elimination of the objects in the discourse of scientific theories, leaving us with structures only. As put by the defenders of such a claim, the idea is that all there is are structures and, if the relevant structures are to be set-theoretical constructs ...

Effect of Welding Process on Microstructural and Mechanical Characteristics of Hardox 600 Steel
Metals, 2017 In the article, the structure and selected mechanical properties of welded Hardox 600 steel are presented. It is shown that, after welding of this material in as-delivered condition (i.e., with post-martensitic structure), structures of lower wear ...
