We tested the hypothesis that neuromechanical uncoupling of the respiratory system forms the mechanistic basis of dyspnea during exercise in the setting of "abnormal" restrictive constraints on ventilation (VE). To this end, we examined the effect of chest wall strapping (CWS) sufficient to mimic a "mild" restrictive lung deficit on the interrelationships between VE, breathing pattern, dynamic ...

Summary In this study we inverted a large set of normal-mode centre frequencies and quality (attenuation) factors, including geodetic data (mass, moment inertia tidal response), using self-consistently-built models the radial elastic anelastic seismic structure Earth. The mantle are constructed petrologic phase equilibria in combination with laboratory-based visco-elastic model that connects di...

We use N-body simulations to explore the effects of tidal stripping on the structure of dwarf spheroidal galaxies (dSphs). Our models assume cosmologically motivated initial conditions where dSphs are modeled as King spheres, embedded in Navarro-Frenk-White dark halos and orbiting the Galactic potential on eccentric orbits. As expected, systems that orbit through dense regions of the Galaxy los...

The tiny general relativistic Lense-Thirring effect can be measured by means of a suitable combination of the orbital residuals of the nodes of LAGEOS and LAGEOS II and the perigee of LAGEOS II. This observable is affected, among other factors, by the Earth’ s solid and ocean tides. They induce long-period orbital perturbations that, over observational periods of few years, may alias the detect...

The effects of barometric pressure and earth tide changes are often observed in ground water level measurements. These disturbances can make aquifer test interpretation difficult by masking the small changes induced by aquifer testing at late times and great distances. A computer utility is now available that automatically removes the effects of barometric pressure and earth tides from water le...

Tidal modulation of ice streams and their adjacent shelves is a real-world experiment to understand ice-dynamic processes. We observe the dynamics Priestley Glacier, Antarctica, using Terrestrial Radar Interferometry (TRI) GNSS. Ocean tides are predominantly diurnal but horizontal GNSS displacements also oscillate semi-diurnally. The oscillations strongest in shelf tidal signatures decay near-l...

The cascade from tides to turbulence has been hypothesized to serve as a major energy pathway for ocean mixing. We investigated this cascade along the Hawaiian Ridge using observations and numerical models. A divergence of internal tidal energy flux observed at the ridge agrees with the predictions of internal tide models. Large internal tidal waves with peak-to-peak amplitudes of up to 300 met...
