Second-order perturbations in Alfvén waves in finite pressure plasma

open access: yesSolar-Terrestrial Physics, 2022
It is shown first that in finite pressure plasma, just as in cold plasma, Alfvén waves created by an initial perturbation generate plasma flows and decreases in the magnetic field, which propagate along with these waves.

Waves in a fluid layer excited by pressure variations above the free surface [PDF]

open access: yesГеосистемы переходных зон
The aim of the paper was to study the problem of waves in a layer of incompressible fluid of constant depth. The interest in the problem arose due to the excitation and propagation of surface waves in the Pacific Ocean as a result of the powerful ...

B waves: a systematic review of terminology, characteristics, and analysis methods

open access: yesFluids and Barriers of the CNS, 2019
Background Although B waves were introduced as a concept in the analysis of intracranial pressure (ICP) recordings nearly 60 years ago, there is still a lack consensus on precise definitions, terminology, amplitude, frequency or origin. Several competing

Transient Friction Analysis of Pressure Waves Propagating in Power-Law Non-Newtonian Fluids

open access: yesApplied Sciences
Modulated pressure waves propagating in the drilling fluids inside the drill string are a reliable real-time communication technology that transmit data from downhole to the surface during oil and gas drilling.

Shock characteristics evolution of detonation waves forward impacting on the solid wall

open access: yesAIP Advances, 2022
The forward reflection of detonation waves on the solid wall will lead to a high pressure rise. The research systematically introduced the theoretical, numerical, and experimental exploration on the shock propagation characteristics of detonation waves ...

Pressure Anomalies Beneath Solitary Waves with Constant Vorticity

open access: yesEng, 2023
While some studies have investigated the particle trajectories and stagnation points beneath solitary waves with constant vorticity, little is known about the pressure beneath such waves.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
