Several recent advances in turbulent dynamo theory are reviewed. High resolution simulations of small-scale and large-scale dynamo action in periodic domains are compared with each other and contrasted with similar results at low magnetic Prandtl numbers. It is argued that all the different cases show similarities at intermediate length scales. On the other hand, in the presence of helicity of ...

The unsaturated zone (UZ) extends across the Earth’s terrestrial surface and is central to many problems related land water resource management. Flow of through UZ typically thought be slow diffusive, such that it could attenuate fluxes dampen variability between atmospheric inputs underlying aquifer systems. This would reduce vulnerability contaminants water-related hazards. Reducing or negati...

The objective of the project is to examine recent progress in two major areas of research – computer science and neuroscience, and their related fields – and to understand whether progress in understanding cognition in living systems has new insights to offer those researching the construction of artificial cognitive systems. * Authors listed in alphabetical order. Authorship of specific sectio...

While large-scale seafloor features (e.g. continental slopes, mid-ocean ridges) help shape the broad patterns of ocean circulation, small-scale rough topography seamounts, abyssal hills) can also impact dynamics in two significant ways. First, they momentum budget through flow steering, blocking and drag force, non-local transfer via generation radiating internal waves dissipation by topographi...

Large scale changes to lipid bilayer shapes are well represented by the Helfrich model. However, there are membrane processes that take place at smaller length scales that this model cannot address. In this work, we present a one-dimensional continuum model that captures the mechanics of the lipid bilayer membrane at the length scale of the lipids themselves. The model is developed using the Co...

Kinematic dynamo theory is presented here for turbulent conductive fluids. We describe how inhomogeneous magnetic fluctuations are generated below the viscous scale of turbulence where the spatial smoothness of the velocity permits a systematic analysis of the Lagrangian path dynamics. We find analytically the moments and multipoint correlation functions of the magnetic field at small yet finit...
