AZP2006 in Progressive Supranuclear Palsy: Outcomes from a Phase 2a Multicenter, Randomized Trial, and Open-Label Extension on Safety, Biomarkers, and Disease Progression. [PDF]

open access: yesMov Disord
Abstract Objectives The aim was to evaluate the safety, tolerability, pharmacokinetics, and potential clinical efficacy of AZP2006, an oral pleiotropic drug modulating progranulin levels, in patients with progressive supranuclear palsy (PSP), a rare tauopathy. Methods A randomized, double‐blind, placebo‐controlled, parallel‐group trial was conducted at

Basic Questions on Artin-Tits groups

open access: green, 2011
This paper is a short survey on four basic questions on Artin-Tits groups: the torsion, the center, the word problem, and the cohomology ($K(\pi,1)$ problem).

The conjectures of Artin-Tate and Birch-Swinnerton-Dyer [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
We provide two proofs that the conjecture of Artin-Tate for a fibered surface is equivalent to the conjecture of Birch-Swinnerton-Dyer for the Jacobian of the generic fibre.

Graph automaton groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2021
In this paper we define a way to get a bounded invertible automaton starting from a finite graph. It turns out that the corresponding automaton group is regular weakly branch over its commutator subgroup, contains a free semigroup on two elements and is ...

Curve graphs for Artin–Tits groups of type B, A∼ and C∼ are hyperbolic

open access: yesTransactions of the London Mathematical Society, 2021
The graph of irreducible parabolic subgroups is a combinatorial object associated to an Artin–Tits group A defined so as to coincide with the curve graph of the (n+1)‐times punctured disk when A is Artin's braid group on (n+1) strands.

Interval groups related to finite Coxeter groups Part II

open access: yesTransactions of the London Mathematical Society, 2023
We provide a complete description of the presentations of the interval groups related to quasi‐Coxeter elements in finite Coxeter groups. In the simply laced cases, we show that each interval group is the quotient of the Artin group associated with the ...

Hilbert series of mixed braid monoid $ MB_{2, 2} $

open access: yesAIMS Mathematics, 2022
Hilbert series is a simplest way to calculate the dimension and the degree of an algebraic variety by an explicit polynomial equation. The mixed braid group $ B_{m, n} $ is a subgroup of the Artin braid group $ B_{m+n} $.

XXL type Artin groups are CAT(0) and acylindrically hyperbolic [PDF]

open access: yes, 2021
We describe a simple locally CAT(0) classifying space for extra extra large type Artin groups (with all labels at least 5). Furthermore, when the Artin group is not dihedral, we describe a rank 1 periodic geodesic, thus proving that extra large type ...

Correlation Functions of Quantum Artin System

open access: yesUniverse, 2020
It was conjectured by Maldacena, Shenker and Stanford that the classical chaos can be diagnosed in thermal quantum systems by using an out-of-time-order correlation function.
