Localized breathing modes in granular crystals with defects [PDF]

open access: yesPhysical Review E, 2009
We investigate nonlinear localized modes at light-mass impurities in a one-dimensional, strongly-compressed chain of beads under Hertzian contacts. Focusing on the case of one or two such "defects", we analyze the problem's linear limit to identify the system eigenfrequencies and the linear defect modes.

Nonlinear dynamics of a rotating shaft with a breathing crack [PDF]

open access: yes, 2011
In this paper, the effects of a breathing crack on the vibratory characteris- tics of a rotating shaft are investigated. A new, simple and robust model composed of two rigid bars connected with a nonlinear flexural spring is proposed.

Spin-wave modes of magnetic bimerons in nanodots

open access: yesNew Journal of Physics, 2022
We report the resonance excitations and the spin-wave modes of a single bimeron in a confined nanodot by using micromagnetic simulations. Magnetic bimerons can be considered as in-plane topological spin textures of magnetic skyrmions, which means that ...

The cerebral cost of breathing: an FMRI case-study in congenital central hypoventilation syndrome. [PDF]

open access: yesPLoS ONE, 2014
Certain motor activities--like walking or breathing--present the interesting property of proceeding either automatically or under voluntary control. In the case of breathing, brainstem structures located in the medulla are in charge of the automatic mode,

Damping properties of the breathing mode in 208Pb

open access: yesPhysics Letters B, 1992
Abstract We study the properties of the isoscalar monopole resonance in 208 Pb, within the framework of a self-consistent model employing a Skyrme force. Including the coupling of the resonance to a set of particle-hole-phonon configurations, we obtain both a good description of the strength function of the mode and a consistent accout of the ...

Breathing dissipative solitons in mode-locked fiber lasers [PDF]

open access: yes, 2019
Dissipative solitons are self-localized coherent structures arising from the balance between energy supply and dissipation. Besides stationary dissipative solitons, there are dynamical ones exhibiting oscillatory behavior, known as breathing dissipative ...

Flexible pressure and temperature dual-mode sensor based on buckling carbon nanofibers for respiration pattern recognition

open access: yesScientific Reports, 2022
Breathing condition is an essential physiological indicator closely related to human health. Wearable flexible breath sensors for respiration pattern recognition have attracted much attention as they can provide physiological signal details for personal ...
