Truncation of Tau selectively facilitates its pathological activities
Journal of Biological Chemistry, 2020 Neurofibrillary tangles of abnormally hyperphosphorylated Tau are a hallmark of Alzheimer's disease (AD) and related tauopathies. Tau is truncated at multiple sites by various proteases in AD brain.

Inference: International Review of Science, 2022 In the mid-1980s, an enigmatic document began circulating in French mathematical circles. Entitled Récoltes et Semailles, it was a lengthy, philosophical and deeply personal tract from the elusive mathematician Alexander Grothendieck, by then living in self-imposed seclusion.

On the Reversibility of Discretization
Mathematics, 2020 “Discretization” usually denotes the operation of mapping continuous functions to infinite or finite sequences of discrete values. It may also mean to map the operation itself from one that operates on functions to one that operates on infinite or finite

Certifying Convergence of Lasserre's Hierarchy via Flat Truncation [PDF]
, 2012 This paper studies how to certify the convergence of Lasserre's hierarchy of semidefinite programming relaxations for solving multivariate polynomial optimization. We propose flat truncation as a general certificate for this purpose.

On noncommutative spherically symmetric spaces [PDF]
, 2014 Two families of noncommutative extensions are given of a general space-time metric with spherical symmetry, both based on the matrix truncation of the functions on the sphere of symmetry.

Scoring rules, ballot truncation, and the truncation paradox
Public Choice, 2022 A voting rule that permits some voters to favor a candidate by providing only the initial segment of their sincere rankings is said to be vulnerable to the truncation paradox. In this paper, we consider four models for counting truncated ballots, optimistic, pessimistic (the most common), averaged, and round-down.

PHF-Core Tau as the Potential Initiating Event for Tau Pathology in Alzheimer’s Disease
Frontiers in Cellular Neuroscience, 2020 Worldwide, around 50 million people have dementia. Alzheimer’s disease (AD) is the most common type of dementia and one of the major causes of disability and dependency among the elderly worldwide.

Truncation Effects in Monte Carlo Renormalization Group Improved Lattice Actions [PDF]
, 1998 We study truncation effects in the SU(3) gauge actions obtained by the Monte Carlo renormalization group method. By measuring the heavy quark potential we find that the truncation effects in the actions coarsen the lattice by 40-50 % from the original ...

Improved results on frequency-weighted balanced truncation and error bounds [PDF]
, 2011 In this paper, we present some new results on frequency-weighted balanced truncation which is a significant improvement on Lin and Chiu's frequency-weighted balanced truncation technique. The reduced-order models, which are guaranteed to be stable in the
