Normal‐Appearing White Matter Injury Mediates Chronic Deep Venous Hypoxia and Disease Progression in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...

Compositions and chemical states on the co-deposition layer of lithiated tungsten of plasma-facing components of EAST

open access: yesNuclear Materials and Energy, 2017
Lithiation is beneficial to enhance plasma performance in EAST by reducing hydrogen and impurities recycling via lithium (Li) wall conditioning. High-Z materials like tungsten (W) have been selected as up–divertor in EAST tokamak.

Benchmarking electron-cloud simulations and pressure measurements at the LHC

open access: yes, 2013
During the beam commissioning of the Large Hadron Collider (LHC) with 150, 75, 50 and 25-ns bunch spacing, important electron-cloud effects, like pressure rise, cryogenic heat load, beam instabilities or emittance growth, were observed. A method has been

Hydrodynamic flow conditions through permeable walls

open access: yesJournal de Physique I, 1992
The flow through permeable walls is studied for a variety of hole dimensions, spacings, and boundary conditions by the method of hydrodynamic cellular automata. The flux measured on the contact section of two adjacent channels is found to scale for all studied hole sizes from 1 to 128, regardless of whether the flow is forced by an imposed pressure ...

Implementing Quantum Gates by Optimal Control with Doubly Exponential Convergence

open access: yes, 2012
We introduce a novel algorithm for the task of coherently controlling a quantum mechanical system to implement any chosen unitary dynamics. It performs faster than existing state of the art methods by one to three orders of magnitude (depending on which ...
