27 Supercritical flow phenomena are fairly common in modern sedimentary environments, yet their 28 recognition and analysis remain difficult in the stratigraphic record. This fact is commonly 29 ascribed to the poor preservation potential of deposits from high-energy supercritical flows. 30 However, the number of flume datasets on supercritical flow dynamics and sedimentary 31 structures is ver...

This article argues that there is nothing inherently bad about power over others – it depends on how used; in many ways does not have to be a zero-sum game; and perspectives strategies for transforming from below, vital as they are, should distract the potentials transformations above. Power can used empower. requires changes mindsets behaviour, with actions like convening, catalysing, facilita...

This paper presents the new boundary condition implemented in the LNEC (Laboratório Nacional de Engenharia Civil) SPH (Smoothed Particle Hydrodynamics) numerical model based on the SPHysics model and on a standard SPH formulation: This piston-type wave-maker now includes dynamic wave absorption and allows the simulation of a semi-infinite flume. Verification of the active wave-maker absorption ...

A relational characterization of cop-win graphs was provided by Nowakowski and Winkler in their seminal paper on the game of Cops and Robbers. As a by-product of that characterization, each cop-win graph is assigned a unique ordinal, which we refer to as a CRordinal. For finite graphs, CR-ordinals correspond to the length of the game assuming optimal play, with the cop beginning the game in a l...
