TL;DR: In this paper, the authors describe a set of benchmark exercises that are designed to test if computer codes that simulate dynamic earthquake rupture are working as intended, and they produce simulation results that include earthquake size, amounts of fault slip, and the patterns of ground shaking and crustal deformation.
Abstract: We describe a set of benchmark exercises that are designed to test if computer codes that simulate dynamic earthquake rupture are working as intended. These types of computer codes are often used to understand how earthquakes operate, and they produce simulation results that include earthquake size, amounts of fault slip, and the patterns of ground shaking and crustal deformation. The benchmark exercises examine a range of features that scientists incorporate in their dynamic earthquake rupture simulations. These include implementations of simple or complex fault geometry, off‐fault rock response to an earthquake, stress conditions, and a variety of formulations for fault friction. Many of the benchmarks were designed to investigate scientific problems at the forefronts of earthquake physics and strong ground motions research. The exercises are freely available on our website for use by the scientific community.

TL;DR: In this article, the authors investigated the character and mechanism of two-way shape memory in Cu-Zn-Al alloys by means of closely controlled thermomechanical cycling and careful measurement of the progressive effect of the particular training routine, as well as by correlary studies of submicrostructural evolution as training proceeds.
Abstract: The character and mechanism of two-way shape memory in Cu-Zn-Al alloys is investigated by means of closely controlled thermomechanical cycling and careful measurement of the progressive effect of the particular “training” routine, as well as by correlary studies of submicrostructural evolution as training proceeds. The results establish the quantitative relationship between the cyclic training routine and the ability of the sample to exhibit two-way shape memory. The variation of numerous training parameters with cycling is presented and interpreted. Microscopic studies indicate that as two-way shape memory training proceeds, specific physical features develop in the parent phase submicrostructure, particularly dislocation tangles and “vestigial” martensite markings; these assist in the nucleation and growth of a preferred martensite plate arrangement during cooling.

TL;DR: In this article, the authors studied the relationship between the Nino-3 sea surface temperature (SST) and the Maritime Continent monsoon rainfall during 1979-2002 and reported that the correlations are mostly negative except in the vicinity of Sumatra and Malay Peninsula (SMP), including the western sections of Java and Borneo, where the correlations range from zero to weakly positive.
Abstract: Several studies have reported that Indonesian rainfall is poorly correlated with El Nino–Southern Oscillation (ENSO) events during the northern winter wet monsoon season. This work studies the relationship between the Nino-3 (5°S–5°N, 150°–90°W) sea surface temperature (SST) and the Maritime Continent monsoon rainfall during 1979–2002. The study indicates that the correlations are mostly negative except in the vicinity of Sumatra and Malay Peninsula (SMP, including the western sections of Java and Borneo), where the correlations range from zero to weakly positive. The monsoon rainfall during ENSO events is influenced by a pair of anomalous Walker cells and a low-level closed circulation centered near the Philippines. East of SMP, the rainfall is negatively correlated with Nino-3 SST. The anomalous low-level wind over the Indian Ocean west of SMP causes rainfall to also be correlated negatively with Nino-3 SST, but rainfall over SMP is sheltered from this effect because of the high mountains along...

TL;DR: In this article, a multiblock Navier-Stokes solver is employed to compute unsteady flow fields around a single flapping airfoil and the unstaired potential flow code is also computed.
Abstract: Thrust generation on a single flapping airfoil and a flapping/stationary airfoil combination in tandem is studied parametrically. A multiblock Navier-Stokes solver is employed to compute unsteady flowfields. The unsteady flowfield around a single flapping airfoil is also computed by an unsteady potential flow code. The numerical solutions predict thrust generation in flapping airfoils and a significant augmentation of thrust in flapping/stationary airfoil combinations in tandem. The propulsive efficiency is found to be a strong function of reduced frequency and the amplitude of the flapping motion. At a flapping amplitude of 0.40 chord lengths and a reduced frequency of 0.10, the propulsive efficiency of a single NACA 0012 airfoil was computed to be more than 70 %. For the airfoil combination in tandem, the propulsive efficiency was augmented more than 40% at a reduced frequency of 0.75 and a flapping amplitude of 0.20 chord lengths when the airfoils are separated by about two chord lengths.

TL;DR: In this paper, the authors present a status report on the present understanding of the physics of atom ejection by ion bombardment and indicate the contributions of molecular dynamics simulations to this research area.
Abstract: This article has two primary objectives: to present a status report on our present understanding of the physics of atom ejection by ion bombardment and to indicate the contributions of molecular dynamics simulations to this research area. Because this application of molecular dynamics is relatively unfamiliar, basic simulation techniques useful in open systems are described in some detail. While this review discusses the current situation, explanations and historical background are necessarily included to place problems in perspective.
