We consider surface-induced ratcheting transport of particles in nano-channels, particularly at room temperature. show that temperature it is possible to achieve about 10 nm size a nano-channel 100 width. The typical velocity such case could be the order few hundred nano-meter when surface undulations are wavelength and amplitude tens nano-meter. At temperature, viscosity fluid enabling nano-ch...

The present paper introduces a comprehensive model capable of describing the behavior of granular materials under cyclic loading. Its main thrust is the introduction of the “Chicago” law in a continuum approach to account for the ratcheting effects. It also emphasizes the rate-dependency as a dissipative mechanism which acts independently or jointly with the ratcheting effect. Non-associated pl...

This paper describes our experiments with a distributed manipulation system. We study a system in which multiple robots cooperate to move large objects such as furniture and boxes using a constrained prehensile manipulation mode, by wrapping ropes around them. The system consists of three manipulation skills: tieing ropes around objects, affecting translations using a flossing manipulation gait...

Sequencing DNA in a synthetic solid-state nanopore is potentially a low-cost and high-throughput method. Essential to the nanopore-based DNA sequencing method is the ability to control the motion of a single-stranded DNA (ssDNA) molecule at single-base resolution. Experimental studies showed that the average translocation speed of DNA driven by a biasing electric field can be affected by ionic ...
