Influence of fabric permeability on breathing phenomenon of supersonic parachute
Journal of Industrial Textiles, 2023 In order to investigate the dynamics and vortex shedding of flexible supersonic canopies, a compressible permeability model combined with fabric structure parameters is proposed, and the periodic oscillation of the supersonic parachute which is referred ...

Frontiers in Neuroscience, 2023 Periodic Cheyne–Stokes breathing (CSB) oscillating between apnea and crescendo–decrescendo hyperpnea is the most common central apnea. Currently, there is no proven therapy for CSB, probably because the fundamental pathophysiological question of how the ...

Periodic breathing at high altitude. [PDF]
IMA journal of mathematics applied in medicine and biology, 2002 Periodic breathing is often associated with heart disease or stroke, and commonly Cheyne-Stokes breathing has a period of about a minute. Periodic breathing also commonly occurs in healthy subjects at high altitude, and here the periods may be much shorter, of the order of 15-20 s.

Oxygen therapy in infants with extreme periodic breathing
, 2023 Periodic breathing (PB) is a respiratory pattern in infants defined as 3 episodes of apneas lasting longer than 3 seconds, separeted by continued respiration of 20 seconds or less. PB is generally thought to be benign, but sometimes PB is extreme (PB >

Characterizing and Modeling Breathing Dynamics: Flow Rate, Rhythm, Period, and Frequency
Frontiers in Physiology, 2022 The characterization of breathing dynamics provides researchers and clinicians the ability to differentiate respiratory compensation, impairment, disease progression, ventilator assistance, and the onset of respiratory failure.

The origin of the period-$2T/7$ quasi-breathing in disk-shaped Gross-Pitaevskii breathers
SciPost Physics, 2022 We address the origins of the quasi-periodic breathing observed in [Phys. Rev.\ X vol. 9, 021035 (2019)] in disk-shaped harmonically trapped two-dimensional Bose condensates, where the quasi-period $T_{\text{quasi-breathing}}\sim$~$2T/7$ and $T$ is the ...

The Periodic Flapping and Breathing of Saturn's Magnetodisk During Equinox [PDF]
, 2018 Periodic variations have been observed in many field and particle properties in Saturn's magnetosphere, modulated at a period close to the planetary rotation rate. Magnetic field observations by Cassini's magnetometer instrument suggest that in the outer

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017 BackgroundDifferent sleep‐disordered breathing (SDB) phenotypes, including coexisting obstructive and central sleep apnea (OSA‐CSA), have not yet been characterized in a large sample of patients with heart failure and reduced ejection fraction (HFrEF ...
