Symbolic Vector Analysis in Plasma Physics [PDF]

, 1997
Many problems in plasma physics involve substantial amounts of analytical vector calculation. The complexity usually originates from both the vector operations themselves and the choice of underlying coordinate system.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Compact shunts for the upper divertor of ASDEX Upgrade [PDF]

AIP Advances
The compact shunts that are mounted in the upper divertor of ASDEX Upgrade are now operational and measure the thermocurrents generated by the temperature difference between the two target plates of the upper divertor cassette.

Clinical Validation of Plasma p‐217tau in Neurological Diseases

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma p‐217tau is a minimally invasive but specific biomarker for diagnosing Alzheimer's disease (AD). However, its disease specificity remains to be clinically evaluated. We validated the reliability of the p‐217tau biomarker in 12 other neurological diseases.

Renormalization and plasma physics [PDF]

, 1980
A review is given of modern theories of statistical dynamics as applied to problems in plasma physics. The derivation of consistent renormalized kinetic equations is discussed, first heuristically, later in terms of powerful functional techniques.

Multi-scale core-edge instabilities and particle acceleration unveiled in EAST ion temperature peak discharge

Nuclear Fusion
Controlling fast particles in tokamaks is crucial for both safe device operation and optimal plasma performance. We report the first observation, on EAST with a fully metallic wall, of a central ion temperature peaking (Ti-peak) regime reaching 9 keV ...

A structure-preserving spline finite element solver for the cold-plasma model [PDF]

EPJ Web of Conferences
We present a spline finite element solver, which preserves the Hamiltonian structure of the coldplasma model as well as several physical invariants, such as the energy, the total charge and the zero divergence of the magnetic field.

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

Variable structure model for flow-induced tonal noise control with plasma actuators [PDF]

, 2008
The objective of this work was to study the effect of plasma actuators in attenuating low-speed flow-induced cavitytones from a control point of view by employing techniques from classical control. A modification of the existingphysics-based linear model

Predictive Ability of Plasma p‐tau217 for β‐Amyloid Status: A Prospective Multicenter Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma tau phosphorylated at threonine 217 (p‐tau217) measured with fully automated platforms has shown high accuracy for Alzheimer's disease (AD) diagnosis, but real‐world multicenter data remain limited. We aimed to validate the diagnostic performance of p‐tau217 for identifying AD pathology in a real‐world multicenter cohort ...
