Trapped Ion Oscillation Frequencies as Sensors for Spectroscopy [PDF]

open access: yesSensors, 2010
The oscillation frequencies of charged particles in a Penning trap can serve as sensors for spectroscopy when additional field components are introduced to the magnetic and electric fields used for confinement. The presence of so-called “magnetic bottles”

Fermi surface reconstruction from bilayer charge ordering in the underdoped high temperature superconductor YBa2Cu3O6+x

open access: yesNew Journal of Physics, 2012
We show that a Fermi surface in underdoped YBa _2 Cu _3 O _6+ _x yielding the distribution of quantum oscillation frequencies observed over a broad range of magnetic field can be reconciled with the wavevectors of charge modulations found in nuclear ...

Radial oscillation of an encapsulated bubble near a planar rigid wall under dual-frequency acoustic excitation in viscoelastic fluids [PDF]

open access: yesUltrasonics Sonochemistry
Microbubbles play an important role in acoustic cavitation, power ultrasonics, and biomedical diagnosis and therapy. However, the influence of surrounding boundary conditions on the dynamic behaviors of an encapsulated bubble requires more in depth ...

Research on the dynamics of multi-storey buildings [PDF]

open access: yesГеосистемы переходных зон, 2023
The design of multi-storey buildings is a natural trend in the development of a modern metropolis. Obtaining exact solutions when studying their own and forced oscillations within the framework of a continuous homogeneous medium model (continuum ...

Zeeman Splitting of Torsional Oscillation Frequencies of Magnetars

open access: yesUniverse, 2023
Magnetars form a special class of neutron stars possessing superstrong magnetic fields and demonstrating power flares triggered by these fields. Observations of such flares reveal the presence of quasi-periodic oscillations (QPOs) at certain frequencies;

Simulation of a tubular cultivator rack of tillage machines under static and dynamic loads [PDF]

open access: yesE3S Web of Conferences, 2023
Curved tubes of non-circular cross section are widely used in various fields of technology. The change in the planned operating modes of various technological processes is associated with the wear of the executing mechanisms, which is caused by unstable ...

Chromatophore activity during natural pattern expression by the squid Sepioteuthis lessoniana: contributions of miniature oscillation. [PDF]

open access: yesPLoS ONE, 2011
Squid can rapidly change the chromatic patterns on their body. The patterns are created by the expansion and retraction of chromatophores. The chromatophore consists of a central pigment-containing cell surrounded by radial muscles that are controlled by

High-frequency oscillation in adolescents [PDF]

open access: yesBritish Journal of Anaesthesia, 2002
High-frequency oscillation (HFO) is a widely used lung-protective ventilatory strategy in paediatric and neonatal acute lung injury. Its safe and effective use has been hindered by inadequate recruitment of the lung during oscillation and, until recently, the lack of an adequately powered oscillator for use in adult practice.We present data from three ...
