Self-assembled lamellar structures composed of block copolymers are simulated by molecular dynamics. The response of a bulk system to external shear is investigated, in particular, the average energy, the entropy production, and the stability of the lamellae's orientation. We distinguish two orientations, a parallel orientation in which the normal to the lamellae sheets lies in the direction of...

Understanding the strength and slip behaviour of tectonic faults is a central problem in earthquake physics and seismichazard assessment1–8. Many major faults, including the San Andreas Fault, are weak compared with the surrounding rock, but the cause of this weakness is debated1. Previous measurements of the frictional strength of San Andreas Fault rocks are too high to explain the observed we...

Reliability is set to become a major concern on emergent large-scale architectures. While there are many parallel languages, and indeed many parallel functional languages, very few address reliability. The notable exception is the widely emulated Erlang distributed actor model that provides explicit supervision and recovery of actors with isolated state. We investigate scalable transparent faul...

Described is a method of parallel pattern fault simulation for synchronous sequential circuits that is based on parallel pattern single fault propagation for combinational circuits as described in [1]. This method of fault simulation was proposed in two independent works published in 1991 [2] and 1992 [3] that were a mere three months apart. In this paper this method shall be referred to as PAR...

We present a group of methods for decomposing an arbitrary 3D volume rotation into a sequence of simple shear (i.e., regular shift) operations. We explore different types of shear operations: 2D beam shear, a shear in one coordinate based on the other two coordinates; 2D slice shear, a shear of a volume slice (in two coordinates) according to the third coordinate; and 2D slice–beam shear, the c...

The transition between the two structural regimes of the Walker Lane and the Basin and Range allows for complex transtensional fault interactions. NWtrending dextral shear in the Walker Lane and WNW extension in the northern Great Basin imparts enhanced extension and pull-apart basins that bring about structural controls for geothermal systems. The Carson Sink is the surface expression of this ...

Interferometric Synthetic Aperture Radar observations of surface deformation due to the 1999 Hector Mine earthquake reveal motion on several nearby faults of the eastern California shear zone. We document both vertical and horizontal displacements of several millimeters to several centimeters across kilometer-wide zones centered on pre-existing faults. Portions of some faults experienced retrog...

We propose three synchronous parallel algorithms for scalable parallel test set partitioned fault simulation. The algorithms are based on a new two-stage approach to parallelizing fault simulation for sequential VLSI circuits in which the test set is partitioned among the available processors. The test set partitioning inherent in the algorithms overcomes the good circuit logic simulation bottl...

Spontaneous bilateral mode II shear ruptures were nucleated on faults in photoelastic Homalite plates loaded in uniaxial compression. Rupture velocities were measured and the interaction between the rupture front and short fault branches was observed using high-speed digital photography. Fault branches were formed by machining slits of varying lengths that intersected the fault plane over a ran...
