Excitation of electrostatic fluctuations by jets in a flaring plasma [PDF]
Astronomy & Astrophysics, 2006 Context. During magnetic reconnection as the proposed basic process of solar flares, hot high speed plasma streams (jets) are ejected from the reconnection site. Jets are sometimes associated with type III radio bursts as signatures of electron beams in the solar corona. Aims.

Suppression and excitation condition of collision on instabilities of electrostatic plasmas
Two-stream (TS) and Bump-On-Tail (BOT) electron distributions can induce instabilities in collisionless plasmas, which is closely related to phenomena in space and fusion plasmas. Collisions can lead to unexpected plasma behavior, especially in dense and/or low temperature plasmas.

Modeling and Experimental Evaluation of Haptic Localization Using Electrostatic Vibration Actuators
IEEE Access, 2023 Touch screen devices have become ubiquitous in modern day-to-day lives. While smaller touchscreen devices provide enough user engagement with meaningful haptic feedback, large touch devices still lack meaningful haptic stimulation.

Linear and Nonlinear Electrostatic Excitations and Their Stability in a Nonextensive Anisotropic Magnetoplasma [PDF]
Symmetry, 2021 In the present work, the propagation of (non)linear electrostatic waves is reported in a normal (electron–ion) magnetoplasma. The inertialess electrons follow a non-extensive q-distribution, while the positive inertial ions are assumed to be warm mobile.

A three million Q factor tuning fork resonator based on a vibration isolation structure
AIP Advances, 2022 The quality factor (Q factor) is one of the most important parameters for a resonant sensor since it determines the performance of the resonant system. The mass distribution imbalance caused by the fabrication error has a great impact on the anchor loss,

Electrostatic and whistler instabilities excited by an electron beam [PDF]
Physics of Plasmas, 2017 The electron beam-plasma system is ubiquitous in the space plasma environment. Here, using a Darwin particle-in-cell method, the excitation of electrostatic and whistler instabilities by a gyrating electron beam is studied in support of recent laboratory experiments.
