We review recent pilot simulations that incorporate feedback from ionising radiation in SPH calculations of star forming clouds. In the case that the ionising radiation source is located within the star forming cloud, the inhomogeneity of the cloud significantly modifies the way that feedback operates compared with spherically symmetric cloud models. Inflow/outflow behaviour develops, combining...

Harmony is a process by which some property of a trigger segment spreads onto one or more undergoer segments. In some languages, any segment that bears a harmonizing property will trigger harmony, while in others some segments bearing that property will trigger harmony while others will not. This paper examines such cases in the nasal vowelconsonant harmony systems of several Malayo-Polynesian....

We review here three main (first-order) mechanisms of stress variation able to influence the triggering of volcanic eruptions and the possible impact on eruption dynamics. They are shortand long-term unloading, seismic energy effects, and changes in far field stress due to geodynamic processes. We present an equilibrium equation for rupture of magma chamber and opening of a dyke up to the surfa...

[1] Large earthquakes can trigger distant earthquakes in geothermal areas. Some triggered earthquakes happen while the surface waves pass through a site, but others occur hours or even days later. Does this prolonged seismicity require a special mechanism to store the stress from the seismic waves that differs from ordinary aftershock mechanisms? These questions have driven studies of long-rang...

Rainfall intensity plays an important role in landslide prediction especially in mountain areas. However, the rainfall intensity of a location is usually interpolated from rainfall recorded at nearby gauges without considering any possible effects of topographic slopes. In order to obtain reliable rainfall intensity for disaster mitigation, this study proposes a rainfall-vector projection metho...

This paper concerns the development of formal approaches for speciication, simulation and validation of real-time reactive systems. Most previous approaches to this problem have focussed on discrete systems wherein the behavior of the system is described as a sequence of discrete events or state changes; they do not provide a satisfactory solution for a wide range of hybrid systems whose behavi...

[1] It’s uncertain whether more near-field earthquakes are triggered by static or dynamic stress changes. This ratio matters because static earthquake interactions are increasingly incorporated into probabilistic forecasts. Recent studies were unable to demonstrate all predictions from the static-stress-change hypothesis, particularly seismicity rate reductions. However, current dynamic stress ...

Although their number may be increased in skin lesions, eosinophils have been rather neglected as possible participants to the pathogenesis of chronic urticaria because of the absence of peripheral eosinophilia in patients with this disease. However, recent data suggest a potentially relevant role played by activated eosinophils both in triggering the tissue factor pathway of coagulation cascad...

The inflammatory mediator LTD4 (leukotriene D4) is present at high levels in many inflammatory conditions, and areas of chronic inflammation have an increased risk for subsequent cancer development. We demonstrate here that following LTD4 stimulation, beta-catenin is translocated to the nucleus, triggering the transcriptional activity of the TCF (T-cell factor)/LEF (lymphoid enhancer factor) fa...

We show a correlation between the occurrence of shallow thrust earthquakes and the occurrence of the strongest tides. The rate of earthquakes varies from the background rate by a factor of 3 with the tidal stress. The highest correlation is found when we assume a coefficient of friction of mu = 0.4 for the crust, although we see good correlation for mu between 0.2 and 0.6. Our results quantify ...
