Cusp height in aortic valves

open access: yes, 2013
ObjectivesSuccessful aortic valve repair must normalize cusp and root dimensions. Limited information is available on the normal dimensions of human cusps, in particular the cusp height.MethodsThe cusp height was measured intraoperatively in 621 patients

Variability of Earth’s ionospheric outflow in response to the dynamic terrestrial exosphere

open access: yesFrontiers in Astronomy and Space Sciences
The most abundant neutral constituent in the exospheric region (i.e., beyond ≈ 500 km altitude) is the atomic hydrogen (H); however, its density distributions predicted by physics-based models have been challenged by satellite-based observations of its ...

Cusp Current System

open access: yes, 2018
Electric currents in the cusp region are reviewed from viewpoints of history and energy conversion. During late 1980s and early 1990s, there were debates on the cause of the cusp region current system (cusp Region 0 field‐aligned current [FAC] and cusp ...

Regionalising the circular economy: A three-step integrative review and gap analysis

open access: yesCleaner Environmental Systems
A Circular Economy (CE) is a promising path to realise sustainable societies across cities, regions, and nations. Yet, the realisation of effective regional circular economies (RCEs) remains underexplored.

A constrained-transport E-CUSP scheme for ideal magnetohydrodynamic equations

open access: yes, 2011
The constrained transport algorithm combined with an E-CUSP scheme is developed to solve the ideal magnetohydrodynamic equations. The algorithm can preserve the divergence-free condition for the magnetic field and maintain the advantages of simplicity ...
