Advanced Science, EarlyView.The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.

Soft factorization in QED from 2D Kac-Moody symmetry
Journal of High Energy Physics, 2018 The soft factorization theorem for 4D abelian gauge theory states that the S $$ \mathcal{S} $$-matrix factorizes into soft and hard parts, with the universal soft part containing all soft and collinear poles.

Advanced Science, EarlyView.Temozolomide treatment activates GSK3β, driving DNMT1 phosphorylation, destabilization, and CD47 promoter hypomethylation in glioblastoma. This epigenetic shift upregulates CD47, enabling TMZ‐treated GBM cells to evade macrophage phagocytosis, survive chemotherapy, and acquire resistance.

THE EIGENVECTORS OF REDUCIBLE MATRICES OVER MIN-PLUS ALGEBRA
BarekengThe eigenvalues and the eigenvectors of a matrix are fundamental concepts in max-plus algebra, especially for square matrices. A communication graph is classified as strongly connected or not, corresponding to irreducible and reducible matrices ...

On Generalized Transitive Matrices
Journal of Applied Mathematics, 2011 Transitivity of generalized fuzzy matrices over a special type of semiring is considered. The semiring is called incline algebra which generalizes Boolean algebra, fuzzy algebra, and distributive lattice.

Seeing the Chemistry of Biomolecular Condensates: In Situ Mapping of Composition and Water Content
Advanced Science, EarlyView.Raman hyperspectral imaging combined with spectral phasor analysis enables a label‐free quantification of proteins, polymers and water density within individual biomolecular condensates. By transforming complex vibrational fingerprints into intuitive compositional maps, the approach reveals the high water content and structural heterogeneity of ...

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections
Advanced Electronic Materials, EarlyView.The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

The dynamical U(n) quantum group
International Journal of Mathematics and Mathematical Sciences, 2006 We study the dynamical analogue of the matrix algebra M(n), constructed from a dynamical R-matrix given by Etingof and Varchenko. A left and a right corepresentation of this algebra, which can be seen as analogues of the exterior algebra representation ...
