Wave Period Variability in a Quiescent Solar Prominence
The Astrophysical JournalOn 2022 September 26, we observed a quiescent solar prominence with H α imaging spectroscopy using the Solar Dynamics Doppler Imager (SDDI) on board the Solar Magnetic Activity Research Telescope (SMART).

Electron plasma oscillations associated with type 3 radio emissions and solar electrons [PDF]
An extensive study of the IMP-6 and IMP-8 plasma and radio wave data was performed to try to find electron plasma oscillations associated with type III radio noise bursts and low-energy solar electrons.

From kink instability to magnetic reconnection to oscillations in solar flares
Fundamental Plasma PhysicsWe show how some different fundamental plasma processes - the ideal kink instability, magnetic reconnection and magnetohydrodynamic oscillations - can be causally linked.

Excitation of Solar Acoustic Oscillations
Symposium - International Astronomical Union, 1997 The stochastic excitation of solar oscillations due to turbulent convection is reviewed. A number of different observational results that provide test for solar p-mode excitation theories are described. I discuss how well the stochastic excitation theory does in explaining these observations.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Hinode/EIS Observation of the Alfvénic Fluctuations in the Quiet Sun
The Astrophysical JournalAlfvénic fluctuations in the corona are regularly observed in EUV imaging and infrared spectroscopic data. We report here on the Doppler velocity fluctuations within the data from the Extreme-Ultraviolet Imaging Spectrometer (EIS) on board Hinode.

Newly Observed Small-Scale Structures in the Quiet Sun and Their Connection to Solar Oscillations [PDF]
, 2009 Our observations of the quiet Sun with the NST have yielded unanticipated results on smal-scale solar dynamic. Althought small-scale solar dynamic have been well-studied, the NST is enabling us to probe finer scale dynamic exploiting higher spatial ...

"Just So" Neutrino Oscillations Are Back
, 1998 Recent evidence for oscillations of atmospheric neutrinos at Super-Kamiokande suggest, in the simplest see-saw interpretation, neutrino masses such that `just so' vacuum oscillations can explain the solar neutrino deficit.
