Due to existence of uncertainties in input geometrical properties of fractures, there is not any unique solution for assessing the stability of slopes in jointed rock masses. Therefore, the necessity of applying probabilistic analysis in these cases is inevitable. In this study a probabilistic analysis procedure together with relevant algorithms are developed using Discrete Fracture Network-Dis...

The upcoming Surface Water and Ocean Topography (SWOT) satellite mission, planned to launch in 2022, is the first mission focus on measuring hydrological processes Earth's surface water. As such, SWOT will vastly expand observations of global rivers ?100 m wide. provide a variety data products, including vector river product containing water elevation (WSE), width, slope, estimated discharge. P...

In this paper, we develop dispersive PDE techniques for the Fermi–Pasta–Ulam (FPU) system with infinitely many oscillators, and show that general solutions to infinite FPU can be approximated by counter-propagating waves governed Korteweg–de Vries (KdV) equation as lattice spacing approaches zero. Our result not only simplifies hypotheses but also reduces regularity requirement in previous stud...

When studying river hydrodynamics and water quality evolution laws on the basis of numerical simulation analysis, it is necessary to carry out topographic interpolation along bend direction measured section, as this can provide accurate reliable data for modeling. In paper, a two-step terrain method based sparse discrete sections proposed by comprehensively considering trends lack monitoring se...

Effective acoustic communication in the face of intense conspecific background noise constitutes a constant sensory challenge in chorusing and colonial species. An evolutionary approach suggests that behavioural and environmental constraints in these species should have shaped signal design and signalling behaviour to enable communication in noisy conditions. This could be attained both through...

Effectiveness of a second phase in metallic glass heterostructures to improve mechanical properties varies widely. Unfortunately, methods to fabricate such heterostructures like foams and composites do not allow controlled variation of structural features. Here we report a novel strategy, which allows us to vary heterostructural features independently, thereby enabling a systematic and quantita...

The proliferation of efficient fishing practices has promoted the depletion of commercial stocks around the world and caused significant collateral damage to marine habitats. Recent empirical studies have shown that marine reserves can play an important role in reversing these effects. Equilibrium metapopulation models predict that networks of marine reserves can provide similar benefits so lon...

The title of my paper comes from an essay by Václav Havel. In his essay, Havel addressed most evocatively the question of the unique power of words for thinking and to influence, for good or for harm, as well as to inform and to educate. As analysts our medium is the word. I suggest that it is of inestimable importance that we are able to listen deeply to our patients' words and to be aware of ...
