The Central Andes are the Earth's highest mountain belt formed by ocean-continent collision. Most of this uplift is thought to have occurred in the past 20 Myr, owing mainly to thickening of the continental crust, dominated by tectonic shortening. Here we use P-to-S (compressional-to-shear) converted teleseismic waves observed on several temporary networks(More)
The paper describes our experiences in the design, implementation and use of load distribution on top of Mach. As a rst step towards load distribution, we provided task migration which is our base mechanism for distributed scheduling. We compared task migration with initial placement. In order to make more accurate scheduling decisions, we instrumented Mach(More)
The neural cell adhesion molecule L1, a member of the immunoglobulin superfamily, mediates cell interactions in the developing and regenerating nervous system of mammals and is also detectable in the immune system and in the epithelia of intestine, skin, lung, and kidney. This diverse pattern of expression begs the question as to the regulatory mechanisms(More)
We quantitatively determine cross sections for rotational decoherence from the decay of nonadiabatic laser-induced alignment in nitrogen and nitrogen-foreign gas mixtures in a temperature range between 80 K and room temperature. The cross section for rotational decoherence in pure nitrogen decreases from 102 A(2) at 80 K to 48 A(2) at 295 K, leading to(More)
The paper investigates the appropriateness of a kernel for load distribution. We demonstrate kernel beneets by presenting a load distribution implementation on top of the Mach kernel. Our load distribution scheme is based o n t h r ee main parts: task migration, load information management and distributed scheduling. We show that it is relatively easy to(More)
