Reactive-infiltration instabilities in rocks. Fracture dissolution
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in theExpand

Untying knots in proteins.
A shoelace can be readily untied by pulling its ends rather than its loops. Attempting to untie a native knot in a protein can also succeed or fail depending on where one pulls. However, thermalExpand

Proteins need to be unfolded when translocated through the pores in mitochondrial and other cellular membranes. Knotted proteins, however, might get stuck during this process, jamming the pore, sinceExpand

Path selection in the growth of rivers
Significance The complex patterns of river networks evolve from interactions between growing streams. Here we show that the principle of local symmetry, a concept originating in fracture mechanics,Expand

Translocation of knotted proteins through a pore
We report the results of molecular dynamics simulations of translocation of knotted proteins through pores. The protein is pulled into the pore with a constant force, which in many cases leads to theExpand

Instabilities in the dissolution of a porous matrix
A reactive fluid dissolving the surrounding rock matrix can trigger an instability in the dissolution front, leading to spontaneous formation of pronounced channels or wormholes. TheoreticalExpand

Microfluidic observation of the onset of reactive-infitration instability in an analog fracture
Reactive-infiltration instability plays an important role in many geophysical problems yet theoretical models have rarely been validated experimentally. We study the dissolution of an analog fractureExpand

A multi-scale molecular dynamics study of the assembly of micron-size supraparticles from 30 nm alkyl-coated nanoparticles.
Atomistic and meso scale computer simulations of nanoparticle aggregation are combined to describe the self-assembly of supraparticles in bulk and on surfaces under vacuum conditions. At the nanoExpand

Translating Wikipedia Articles: A Preliminary Report on Authentic Translation Projects in Formal Translator Training
TLDR
Wikipedia translation as a genuine translation project appears to be a natural application of, and a welcome addition to, the social constructivist paradigm in education. Expand

Stabilizing effect of knots on proteins
Molecular dynamics studies within a coarse-grained, structure-based model were used on two similar proteins belonging to the transcarbamylase family to probe the effects of the knot in the nativeExpand
