Non-linear isocurvature perturbations and non-Gaussianities [PDF]

, 2008
24 pagesWe study non-linear primordial adiabatic and isocurvature perturbations and their non-Gaussianity. After giving a general formulation in the context of an extended $\delta N$ formalism, we analyse in detail two illustrative examples. The first is

Observation of island-like structures in synchrotron imaging emitted by runaway electrons on EAST

Nuclear Fusion
This paper reports on the experimental observation and numerical reconstruction of island-like structures in synchrotron imaging emitted by runaway electrons (REs) on Experimental Advanced Superconducting Tokamak. During low-density ohmic discharges with

Posterior Disconnection Syndrome in Early‐Stage Adult‐Onset Cerebral Adrenoleukodystrophy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Adult‐onset cerebral adrenoleukodystrophy is potentially treatable but often difficult to recognize before advanced cerebral involvement. Herein, we describe three men with early‐stage disease who initially presented with subtle visual complaints rather than subcortical dementia. Targeted neuropsychological testing revealed higher‐order visual

Stochastic Transport Modeling of Resonant Magnetic Perturbations in DIII-D [PDF]

, 2006
Three-dimensional two-fluid simulations of heat transport due to resonant magnetic perturbations of tokamaks have been computed by coupling the TRIP3D field line tracing code to the E3D edge transport code.

Impact of error fields and error field correction on heat fluxes in SPARC

Nuclear Fusion
Using a single toroidal array of coils to reduce the $m,n = 2,1$ resonant error field (EF) produced by the misalignment of the axisymmetric coils in SPARC can result in the enhancement of the local divertor heat fluxes. Managing high divertor heat fluxes

Changes in Immune‐Inflammation Status and Prognosis in Pregnancy‐Related Cerebral Venous Thrombosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Distinguishing pathological changes from physiological adaptations in pregnancy‐related cerebral venous thrombosis (CVT) is clinically challenging. This study aimed to characterize coagulation, immune‐inflammation, and dehydration status in these patients and assess their prognostic value.

Influence of toroidal field ripple and resonant magnetic perturbations on global ¹³C transport in ASDEX Upgrade

, 2014
In this study, 3D orbit-following simulations with the ASCOT code of a tracer injection experiment on ASDEX Upgrade (AUG) are carried out to investigate the influence of toroidal field (TF) ripple and resonant magnetic perturbations (RMPs) on global 13C ...

Simulations of NBI ion losses with 3D magnetic perturbations and charge exchange on EAST

Nuclear Fusion
Guiding-center orbit-following simulations of fast ion losses for two neutral beam injections (NBIs) with three-dimensional (3D) magnetic perturbations and charge exchange (CX) by the GYCAVA code are presented. Here, 3D magnetic perturbations include the

Early Clinical and Cerebrospinal Fluid Predictors of 1‐Year Recurrence in Autoimmune GFAP Astrocytopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP‐A) is an inflammatory central nervous system disorder with variable outcomes. Relapse occurs in a subset of patients, but early predictors remain unclear. We aimed to identify admission‐available features associated with 1‐year recurrence and develop an interpretable ...

Gyrokinetic simulations of the effects of magnetic islands on microturbulence in KSTAR

Nuclear Fusion
Gyrokinetic simulations are utilized to study effects of magnetic islands (MIs) on the ion temperature gradient (ITG) turbulence in the KSTAR tokamak with resonant magnetic perturbations. Simulations show that the transport is controlled by the nonlinear
