Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Confins, 2020 Two questions triggered this research: From the moment that maps are considered historical sources, how are they chosen and used as sources? Do the narratives that deal with space and spatialities of the past out of Geography and the map do so from a set

Rocky Mountain Journal of Mathematics, 1996 This paper examines when a moment map exists for a symplectic torus action on a compact manifold. Having in mind that a moment map for a \(G\)-action restricts to a moment map for the action of a Lie subgroup \(H\subset G\), then, nonexistence results for \(S^1\)-actions extend to nonexistence results for torus actions.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Symplectic Reduction and Convexity of Moment Maps [PDF]
, 2017 This thesis is was written as part of a contribution to a book on symplectic geometry. The first section is corresponds to a chapter on symplectic reduction and the second section to a chapter on convexity of moment maps for torus actions.

Permuting actions, moment maps and the generalized Seiberg-Witten equations [PDF]
, 2016 In this thesis, we study properties and the geometry related to the generalization of the Seiberg-Witten equations introduced by Taubes and Pidstrygach. A crucial ingrediant to these equations is a hyperkähler manifold M with a permuting Sp(1)-action. We

Moment maps and diffeomorphisms [PDF]
Asian Journal of Mathematics, 1999 Some times ago in a very nice paper, \textit{M. F. Atiyah} and \textit{R. Bott} [Philos. Trans. R. Soc. Lond., Ser. A 308, 523-615 (1983; Zbl 0509.14014)], proved that the curvature of a connection on a bundle over a surface can be viewed as the momentum corresponding to the action of the gauge group.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Quantum Moment Map and Invariant Integration Theory on Quantum Spaces
Acta Polytechnica, 2011 It is shown that, on the one hand, quantum moment maps give rise to examples for the operator-theoretic approach to invariant integration theory developed by K.-D.

Non-Hamiltonian Actions and Lie-Algebra Cohomology of Vector Fields
Symmetry, Integrability and Geometry: Methods and Applications, 2009 Two examples of Diff^+S^1-invariant closed two-forms obtained from forms on jet bundles, which does not admit equivariant moment maps are presented.
