Sorting Ions by How Fast They Move

چکیده
Researchers predict that a “flashing” electric ratchet could separate same-charge ions by their diffusion coefficients, possibility improve the energy efficiency of processes such as water desalination and purification.

How fast does Langton’s ant move?
The automaton known as ‘Langton’s ant’ exhibits a dynamical transition from a disordered phase to an ordered phase where the particle dynamics (the ant) produces a regular periodic pattern (called ‘highway’). Despite the simplicity of its basic algorithm, Langton’s ant has remained a puzzle in terms of analytical description. Here I show that the highway dynamics obeys a discrete equation where...
متن کاملCollectives and How They Move: A Tale of Two Classifications
Collective phenomena and their associated movement patterns are ubiquitous in everyday life. However, even though we need to be able to reason about these phenomena, especially their movement patterns, research suggests that we do not currently possess the tools for doing so. Research has been carried out into the movement patterns of particular types of collective but there appears to be no re...
متن کاملFast Sorting by Reversal
Analysis of genomes evolving by inversions leads to a combinatorial problem of sorting by reversals studied in detail recently. Following a series of work recently, Hannenhalli and Pevzner developed the rst polynomial algorithm for the problem of sorting signed permutations by reversals and proposed an O(n 4) implementation of the algorithm. In this paper we exploit a few combinatorial properti...
متن کاملVision affects how fast we hear sounds move.
There is a growing body of knowledge about the behavioral and neural correlates of cross-modal interactions in the perception of motion direction, as well as about the computations that underlie unimodal visual speed processing. Yet, the multisensory contributions to the perception of motion speed remain largely uncharted. Here we show that visual motion information exerts a profound influence ...
متن کاملMichael Sixt: Love the way they move
A cell's job description is reflected in both its physical form and its behavior. For example , fibroblasts and epithelial cells need to stick tightly to each other to hold tissues together. So they tend to spread out, hold tightly to surfaces, and move about only slowly. Leukocytes, on the other hand, need to move about a lot and cover large distances as they patrol the body for signs of infec...
