Magnons and electromagnons in a spin-lattice-coupled frustrated magnet CuFeO2 as seen via inelastic neutron scattering

open access: yes, 2011
We have investigated spin-wave excitations in a four-sublattice (4SL) magnetic ground state of a frustrated magnet CuFeO2, in which `electromagnon' (electric-field-active magnon) excitation has been discovered by recent terahertz time-domain spectroscopy

Complex networks in brain electrical activity

open access: yes, 2005
We analyze the complex networks associated with brain electrical activity. Multichannel EEG measurements are first processed to obtain 3D voxel activations using the tomographic algorithm LORETA.

A quasi-periodic fast-propagating magnetosonic wave associated with the eruption of a magnetic flux rope

open access: yes, 2017
Using high temporal and high spatial resolution observations taken by the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory, we present the detailed observational analysis of a high quality quasi-periodic fast- propagating (QFP ...

Solving the stationary Liouville equation via a boundary element method

open access: yes, 2012
Intensity distributions of linear wave fields are, in the high frequency limit, often approximated in terms of flow or transport equations in phase space.

Wave intensity analysis in the ventricles, carotid and coronary arteries – What has been learnt during the last 25 years?: Part 2

open access: yes, 2014
Wave intensity analysis (WIA) was introduced 25 years ago for the study of arterial wave travel and has since been established as a powerful tool for the investigation of cardio-vascular interaction.

Pulse wave analysis in Anesthesia and Intensive Care.

open access: yesRevista Electrónica AnestesiaR , 2020
 La frecuencia y la forma del pulso arterial han sido empleadas desde hace milenios en un amplio abanico de escenarios clínicos. Cada componente de la onda de la presión arterial; presión pico, presión diastólica, tiempo de eyección, ascenso de la presión arterial durante la sístole y presión arterial media son el resultado de una compleja ...

ANALYSIS OF THE WAVE PACKET PARAMETERS BASED ON DYNAMIC EVALUATION OF THE SPECTRAL COMPONENTS PHASE [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2013
The method of dynamic analysis for the wave packet parameters is considered. The method involves selection and evaluation of the amplitudes and phases of the separate monochromatic components of a wave packet.
