Segregation and mixing of dissimilar grains is a problem in many industrial and pharmaceutical processes, as well as in hazardous geophysical flows, where the sizedistribution can have a major impact on the local rheology and the overall run-out. In this paper, a simple binary mixture theory is used to formulate a model for particlesize segregation and diffusive remixing of large and small part...

It is often desirable to consider an object’s movement over space and time from the perspective of different levels of detail or granularity. Changing to a more detailed view uncovers information that otherwise is unknown. Conversely, moving to a simpler view can improve our understanding of the movement patterns of an object. This paper considers shifts in granularity over geospatial lifelines...

We present the combined efforts of a research network designed to address many challenges in experimental modelling debris flow phenomena. The approach has been use apparatuses different functional arrangement and at scale with identical commonly sourced materials from highly idealised (dry, coarse uniform) complex (well graded, segregating, fluid saturated). Here we briefly some key findings p...

We present an adaptive resolution simulation of protein G in multiscale water. We couple atomistic water around the protein with mesoscopic water, where four water molecules are represented with one coarse-grained bead, farther away. We circumvent the difficulties that arise from coupling to the coarse-grained model via a 4-to-1 molecule coarse-grain mapping by using bundled water models, i.e.,...

High speed gas flows occur during the movement of aircrafts, rockets, and descent vehicles, as well in combustion chambers, nozzles, many other technological applications [...]

We use a graph-theoretical landscape modeling approach to investigate how to identify central patches in the landscape as well as how these central patches influence (1) organism movement within the local neighborhood and (2) the dispersal of organisms beyond the local neighborhood. Organism movements were theoretically estimated based on the spatial configuration of the habitat patches in the ...

Neural responses are commonly studied in terms of "tuning curves," characterizing changes in neuronal response as a function of a continuous stimulus parameter. In the motor system, neural responses to movement direction often follow a bell-shaped tuning curve for which the exact shape determines the properties of neuronal movement coding. Estimating the shape of that tuning curve robustly is h...

In the motor system, neural responses to 24 movement-direction often follow a bell-shaped tuning curve, whose exact shape determines the properties of 25 neuronal movement coding.
