One-dimensional vertical dust strings in a glass box

, 2011
The oscillation spectrum of a one-dimensional vertical dust string formed inside a glass box on top of the lower electrode in a GEC reference cell was studied. A mechanism for creating a single vertical dust string is described.

Interaction energy-based power coupling oscillation analysis and suppression of grid-forming converter connected system

International Journal of Electrical Power & Energy Systems
The power coupling effect of the grid-forming converter will cause instability oscillation when it connects to low-voltage short-distance transmission lines. To solve this problem, this paper presents an energy interaction analysis method for oscillation

Ultrabroadband Excitation of Hot Carriers in Plasmonic Nanorods Revealed by Two‐Dimensional Electronic Spectroscopy

Advanced Optical Materials, EarlyView.
This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Active damping control of multi-scale oscillations in new energy grid connection considering wideband negative resistance characteristics

Results in Engineering
Due to the stochasticity and complexity of renewable energy grid-connected systems, conventional control methods are limited to single-frequency-point regulation and lack broadband adaptability, making it difficult to effectively suppress wideband ...

The effect of primordial fluctuations on neutrino oscillations

, 2008
Recent work has shown that neutrino oscillations in matter can be greatly enhanced by flips between mass eigenstates if the medium is fluctuating with a period equal to the neutrino oscillation length.
