Forced oscillation technique (FOT) is a non-invasive method for measurement of respiratory resistance and reactance at various frequencies (commonly 4–50 Hz)1 using changes in pressure and airflow by applying sound waves from a loudspeaker during quiet breathing. As it does not require breathing ...
The modes of 1D and 2D vortex core structures are schematically illustrated in Fig.4c–e, which were confirmed by calculating inverse FFT corresponding to each oscillation mode (See Supplementary Figs.4,5, Supplementary Notes3,4). For the 1D vortex core structure (See Fig.4c, Supplementary Fig...
Atmospheric Oscillations – Teleconnections include the Arctic Oscillation (AO), Antarctic Oscillation (AAO), North Atlantic Oscillation (NAO), North Pacific Oscillation (NPO), the Madden / Julian Oscillation (MJO), Equatorial Indian Ocean Oscillation (EQUINOO) and Southern Oscillation (SO): The Arcti...
In a recent review, VanRullen and Koch (2003) postulated that alpha and nested gamma cycles produce ‘discrete perception’ in which gamma waves contain the information of each snapshot, with the organization of the ensemble of snapshots mediated by the alpha waves. That is, those events repre...
These can become stationary for days and block the normal circulation of the atmosphere. The negative AO/NAO is associated with a slowed polar vortex and polar jet stream. When the jet stream slows, it meanders in a waveform pattern (Rossby waves). The general effect is illustrated below (...

systematically related to mid and high-latitude teleconnections across the Eurasian continent via eastward-propagating quasi-stationary Rossby waves instigated over the Atlantic and terminating in the northeastern Pacific. These findings underscore the importance of rapidly evolving dynamical processes in ...
The presence of a static tilt between the inner core and mantle is an ongoing discussion encompassing the geodynamic state of the inner core. Here, we confirm an approximate 8.5 yr signal in polar motion is the inner core wobble (ICW), and find that t
The Madden–Julian Oscillation (MJO) is a slow-moving tropical mode that produces a planetary-scale envelope of convective storms. By exciting Rossby waves, the MJO creates teleconnections with far-reaching impacts on extratropical circulation and weathe
