Does High Plasma-β Dynamics "Load" Active Regions?

Does High[Plasma]-β Dynamics “Load” Active Regions?

Using long-duration observations in the He II 304Å passband of the Solar and Heliospheric Observatory (SOHO) Extreme-ultraviolet Imaging Telescope (EIT) we investigate the spatial and temporal appearance of impulsive intensity fluctuations in the pixel light curves. These passband intensity fluctuations come from plasma emitting in the chromosphere, transition region and lowest portions of the ...

Does the dynamics of sine-Gordon solitons predict active regions of DNA?

In this work we analyze the possibility that soliton dynamics in a simple nonlinear model allows functionally relevant predictions of the behaviour of DNA. This suggestion was first put forward by Salerno [Phys. Rev. A 44, 5292 (1991)] by showing results indicating that sine-Gordon kinks were set in motion at certain regions of a DNA sequence that include promoters. We revisit that system and s...

β-amyloid dynamics in human plasma.

OBJECTIVES To investigate dynamic changes in human plasma β-amyloid (Aβ) concentrations, evaluate the effects of aging and amyloidosis on these dynamics, and determine their correlation with cerebrospinal fluid (CSF) Aβ concentrations. DESIGN A repeated plasma and CSF sampling study. SETTING The Washington University School of Medicine in St Louis, Missouri. PARTICIPANTS Older adults with...

Dynamics of Active Regions Revealed by Tracking of Doppler Features

We investigate the large-scale horizontal dynamics of active regions in the 23rd solar cycle. The large-scale horizontal velocity fields were measured applying the local correlation tracking (LCT) algorithm to the processed high-cadence full-resolution full-disc MDI Dopplergrams. We performed the selection of NOAA active regions in the available dataset and followed their individual evolution i...
