Dynamical Systems Method (DSM) for solving nonlinear operator equations in Banach spaces

open access: yes, 2012
Let F (u) = h be a solvable operator equation in a Banach spaceX with a Gateaux differentiable norm. Under minimal smoothness assumptions on F, sufficient conditions are given for the validity of the Dynamical Systems Method (DSM) for solving the above ...

Posterior Cortical Atrophy in the Asia‐Pacific: A Report From the PCA Asian Workgroup

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Posterior Cortical Atrophy (PCA) is a distinct dementia syndrome primarily affecting spatial abilities and visual processing. It is associated with degeneration in the posterior part of the brain. PCA is subclassified into PCA‐pure and PCA‐plus syndromes based on consensus criteria.

The norm of an averaging operator [PDF]

open access: yes, 2001
We consider the operator $A: \ell^2 \to \ell^2$ defined by $A(a) = b$ for $a=(a_n)$ and $b=(b_n)$ with $b_n=\dfrac1n (a_1+a_2+\dots + a_n)$.

Operator norm localization property of metric spaces under finite decomposition complexity

open access: yes, 2009
The notions of operator norm localization property and finite decomposition complexity were recently introduced in metric geometry to study the coarse Novikov conjecture and the stable Borel conjecture.

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Operator growth in disordered spin chains: Indications for the absence of many-body localization

open access: yesPhysical Review Research
We consider the spreading of a local operator A in one-dimensional many-body systems with Hamiltonian H by calculating the k-fold commutator [H,[H,[...,[H,A]]]].

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.
