Adaptive anomaly detection disruption prediction starting from first discharge on tokamak [PDF]

open access: yesNuclear Fusion
Plasma disruption presents a significant challenge in tokamak fusion, especially in large-size devices like ITER, where it causes severe damage. While current data-driven machine learning methods perform well in disruption prediction, they require ...

Disruption of hierarchical predictive coding during sleep [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Significance Sleeping disrupts the conscious awareness of external sounds. We investigated the stage of processing at which this disruption occurs. In the awake brain, when a regular sequence of sounds is presented, a hierarchy of brain areas uses the available regularities to predict forthcoming sounds and to respond with a series of ...

C-clamp and pelvic packing for control of hemorrhage in patients with pelvic ring disruption [PDF]

open access: yes, 2011
BACKGROUND: Exsanguinating hemorrhage is the major cause of death in patients with pelvic ring disruption. AIMS: The aim of this study was to document outcomes after the stabilization of pelvic ring injuries by a C-clamp and control of hemorrhage ...

Initial analytical theory of plasma disruption and experimental evidence

open access: yesScientific Reports, 2023
It is a great physical challenge to achieve controlled nuclear fusion in magnetic confinement tokamak and solve energy shortage problem for decades. In tokamak plasma, large-scale plasma instability called disruption will halt power production of reactor

Cerebellar rTMS disrupts predictive language processing [PDF]

open access: yesCurrent Biology, 2012
The human cerebellum plays an important role in language, amongst other cognitive and motor functions [1], but a unifying theoretical framework about cerebellar language function is lacking. In an established model of motor control, the cerebellum is seen as a predictive machine, making short-term estimations about the outcome of motor commands.
