DIAMAGNETIC MODULATION OF TRANSVERSE GALVANOMAGNETIC EFFECTS IN LONGITUDINAL AUTOSOLITON IN P-INSB

open access: yesВестник Северо-Кавказского федерального университета, 2022
Experiments show that Ettingshausen effect that is revealed in longitudinal autosoliton in transverse magnetic field that causes movement in the autosoliton can be suppressed with diamagnetism, which appears in the longitudinal magnetic field. Current in

Data-Driven Diagnostics of Mechanism and Source of Sustained Oscillations [PDF]

open access: yes, 2015
Sustained oscillations observed in power systems can damage equipment, degrade the power quality and increase the risks of cascading blackouts. There are several mechanisms that can give rise to oscillations, each requiring different countermeasure to ...

Hydrodynamics Study of Riser with Helical Strakes Oscillating in Flow

open access: yesShanghai Jiaotong Daxue xuebao, 2021
To reduce the vibration damage to the riser, hydrodynamic parameters of a smooth riser and a riser with triple symmetrically distributed helical strakes are evaluated in an experiment. The wave and current in natural environment are conceptualized to the

A sharp oscillation result for second-order half-linear noncanonical delay differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
In the paper, new single-condition criteria for the oscillation of all solutions to a second-order half-linear delay differential equation in noncanonical form are obtained, relaxing a traditionally posed assumption that the delay function is ...

Neutrino oscillations [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2013
This review summarizes recent experimental and theoretical progress in determining neutrino mixing angles and masses through neutrino oscillations. We describe the basic physics of oscillation phenomena in vacuum and matter, as well as the status of solar, reactor, atmospheric, and accelerator neutrino experiments that probe these phenomena.

A mechanism for high-frequency oscillation in ramjet combustors and afterburners [PDF]

open access: yes, 1956
An experimental investigation was made of the behavior of a small two-dimensional combustion chamber, burning a uniform mixture of air and fuel vapor under conditions of high-frequency oscillation or screech.

Drums of Doubt: On the Rhythmical Origins of Poetic and Scientific Exploration

open access: yesHungarian Studies Yearbook, 2019
In his article “Drums of Doubt: On the Rhythmical Origins of Poetic and Scientific Exploration” Caius Dobrescu argues that even though the sciences and arts of doubt have never been connected to the notion of rhythm, doubt is a form of energy, and more ...

AC Oscillation of a Spin Soliton Driven by a Constant Force

open access: yes, 2020
The phenomena of AC oscillation generated by a DC drive, such as the famous Josephson AC effect in superconductors and Bloch oscillation in solid physics, are of great interest in physics.

Cilia oscillations

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2019
Cilia, or eukaryotic flagella, are microscopic active filaments expressed on the surface of many eukaryotic cells, from single-celled protozoa to mammalian epithelial surfaces. Cilia are characterized by a highly conserved and intricate internal structure in which molecular motors exert forces on microtubule doublets causing cilia oscillations.

Oscillatory results for second-order noncanonical delay differential equations [PDF]

open access: yesOpuscula Mathematica, 2019
The main purpose of this paper is to improve recent oscillation results for the second-order half-linear delay differential equation \[\left(r(t)\left(y'(t)\right)^\gamma\right)'+q(t)y^\gamma(\tau(t))= 0, \quad t\geq t_0,\] under the condition \[\int_ ...
