A Prospective Study of Individuals at Risk of Multiple Sclerosis Informs the Design of Primary Prevention Studies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

A method of adaptation between steepest-descent and Newton's algorithm for multichannel active control of tonal noise and vibration [PDF]

open access: yes, 2014
Active control methods have been applied to a number of practical problems in which it is necessary to control a tonal disturbance. For example, the control of engine noise and vibration in vehicles, propeller noise in aircraft and the vibration produced

Influence of plasma-enhanced combustion on RBCC engine using URANS

open access: yesScientific Reports
The rocket-based combined-cycle (RBCC) engine is regarded as one of the most viable propulsion systems for single-stage-to-orbit launch vehicles. Because of the relatively low total temperature of the incoming flow, it is difficult to maintain sustained ...

Active vibration control of doubly-curved panels [PDF]

open access: yes, 2014
This thesis considers active control of the vibration of doubly-curved panels. Such panels are widely used in vehicles such as cars and aircraft, whose vibration is becoming more problematic as the weight of these vehicles is reduced to control their CO2

Stem Cell Transplantation in Friedreich Ataxia: Cure for Leukemia but No Effect on Neurological Progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Friedreich Ataxia (FRDA) is a neurodegenerative disorder of children and young adults associated with cardiomyopathy and other systemic complications. We report a 10‐year‐old girl who presented simultaneously with Acute Myelogenous Leukemia and FRDA who was successfully treated for her leukemia with allogeneic hematopoietic stem cell ...
