Ratcheted diffusion transport through crowded nanochannels
The problem of transport through nanochannels is one of the major questions in cell biology, with a wide range of applications. In this paper we discuss the process of spontaneous translocation of molecules (Brownian particles) by ratcheted diffusion: a problem relevant for protein translocation along bacterial flagella or injectosome complex, or DNA translocation by bacteriophages. We use mole...
متن کاملCollective Transport with Obstacle Avoidance through Socially-Mediated Negotiation
In this dissertation we present a novel negotiation strategy that allows different robots to perform collective transport in the presence of obstacles. The coordination of the different robots involved can be difficult, as their sensor perceptions can be different or conflicting. For example, at a given moment, one robot perceives only the goal direction, another perceives an obstacle to avoid ...
متن کاملDiffusion in a crowded environment.
We analyze a pair of diffusion equations which are derived in the infinite system-size limit from a microscopic, individual based, stochastic model. Deviations from the conventional Fickian picture are found which ultimately relate to the depletion of resources on which the particles rely. The macroscopic equations are studied both analytically and numerically, and are shown to yield anomalous ...
متن کاملStructures with pistes - different sizes
We generalize [5] and introduce structures with pistes which may have different number of models in every cardinality. 1 Structures with pistes–general setting. Assume GCH. As in [5], the first part (1.1) describes this ”linear” part of conditions in the main forcing. It is called a wide piste and incorporates together elementary chains of models of different cardinalities. The main forcing, de...
متن کاملCooperative Transport of Objects of Different Shapes and Sizes
This paper addresses the design of control policies for groups of up to 16 simple autonomous mobile robots (called s-bots) for the cooperative transport of heavy objects of different shapes and sizes. The s-bots are capable of establishing physical connections with each other and with the object (called prey). We want the s-bots to self-assemble into structures which pull or push the prey towar...
