Cancer-associated fibroblasts (CAFs) support tumorigenesis by stimulating angiogenesis, cancer cell proliferation, and invasion. We demonstrate that CAFs also mediate tumor-enhancing inflammation.… Expand
Numerical modeling of the geodynamo: Mechanisms of field generation and equilibration
- P. Olson, U. Christensen, G. Glatzmaier
- Physics
- 10 May 1999
Numerical calculations of fluid dynamos powered by thermal convection in a rotating, electrically conducting spherical shell are analyzed. We find two regimes of nonreversing, strong field dynamos at… Expand
PPARδ regulates multiple proinflammatory pathways to suppress atherosclerosis
- G. Barish, A. Atkins, +9 authors C. Lee
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 18 March 2008
Lipid homeostasis and inflammation are key determinants in atherogenesis, exemplified by the requirement of lipid-laden, foam cell macrophages for atherosclerotic lesion formation. Although the… Expand
The time-averaged magnetic field in numerical dynamos with non-uniform boundary heat flow
- P. Olson, U. Christensen
- Physics
- 1 December 2002
SUMMARY The time-averaged geomagnetic field on the core‐mantle boundary is interpreted using numerical models of fluid dynamos driven by non-uniform heat flow. Dynamo calculations are made at Prandtl… Expand
Mantle plumes control magnetic reversal frequency
Magnetic reversal frequency correlates inversely with mantle plume activity for the past 150 Ma, as measured by the volume production rate of oceanic plateaus, seamount chains, and continental flood… Expand
An experimental study of subduction and slab migration
- C. Kincaid, P. Olson
- Geology
- 10 December 1987
Results of fluid dynamical experiments on the behavior of subducted slabs are presented that address two important characteristics of subduction: slab penetration through the transition zone and… Expand
A laboratory model of subduction zone anisotropy
- J. Buttles, P. Olson
- Geology
- 15 December 1998
Abstract Measurements of split seismic shear-waves near Pacific subduction zones show that fast polarization directions are primarily trench-parallel in the seaward-side mantle beneath a subducting… Expand
Experiments on convection in Earth’s core tangent cylinder
- J. Aurnou, S. Andreadis, L. Zhu, P. Olson
- Physics
- 15 July 2003
Abstract Results of thermal convection experiments in a rotating fluid with a geometry similar to the Earth’s core tangent cylinder are presented. We find four different states. In order of… Expand
Structure of axisymmetric mantle plumes
- P. Olson, G. Schubert, Charles Anderson
- Geology
- 10 April 1993
Results of high-resolution numerical calculations of axisymmetric thermal plumes in an infinite Prandtl number fluid with thermally activated viscosity are used to infer the structure of axisymmetric… Expand
