Travel time tomography with adaptive dictionaries
Michael Bianco, Peter Gerstoft
We develop a 2D travel time tomography method which regularizes the inversion by modeling groups of slowness pixels from discrete slowness maps, called patches, as sparse linear co…
Optimal heat transfer and optimal exit times
Florence Marcotte, Charles R. Doering, Jean-Luc Thiffeault +1
A heat exchanger can be modeled as a closed domain containing an incompressible fluid. The moving fluid has a temperature distribution obeying the advection-diffusion equation, wit…
Iron Snow in the Martian Core?
Christopher Davies, and Anne Pommier
The decline of Mars' global magnetic field some 3.8-4.1 billion years ago is thought to reflect the demise of the dynamo that operated in its liquid core. The dynamo was probably p…
Geomagnetic spikes on the core-mantle boundary
Christopher Davies, Catherine Constable
Extreme variations of Earth's magnetic field occurred in the Levant region around 1000 BC, when the field intensity rapidly rose and fell by a factor of 2. No coherent link current…
Heat Flow and Boundary Heterogeneity in Rotating Convection
Jon E. Mound, Christopher J. Davies
Convection in the metallic cores of terrestrial planets is likely to be subjected to lateral variations in heat flux through the outer boundary imposed by creeping flow in the over…
Statistical state dynamics of weak jets in barotropic beta-plane turbulence
Nikolaos A. Bakas, Navid C. Constantinou, Petros J. Ioannou
Zonal jets in a barotropic setup emerge out of homogeneous turbulence through a flow-forming instability of the homogeneous turbulent state (`zonostrophic instability') which occur…
