Abstract As the length scales of smallest technology continue to advance beyond micron scale it becomes increasingly important equip robotic components with means for intelligent and autonomous decision making limited information. With help a tabular Q-learning algorithm, we design model training microswimmer, navigate quickly through an environment given by various different scalar motility fi...

Abstract Dense active systems are widespread in nature, examples range from bacterial colonies to biological tissues. clusters of particles can be obtained by increasing the packing fraction system or taking advantage a peculiar phenomenon named motility-induced phase separation (MIPS). In this work, we explore diagram two-dimensional model glass and show that disordered materials develop rich ...

Abstract The demixing and sorting strategies for chiral active mixtures are crucial to the biochemical pharmaceutical industries. However, it remains uncertain whether mixed particles can spontaneously demix without aid of specific strategies. In this paper, we investigate behaviors binary in a model understand mechanism mixtures. We demonstrate that motility-induced phase separation (MIPS). hi...

We predict that the average size of persistence-induced clusters formed by run-and-tumble bacteria in narrow channels increases when tumbling rates are more diverse. The effect may be strong for E. coli and present throughout active matter.

Active droplets are artificial microswimmers built from a liquid dispersion by microfluidic tools and showing self-propelled motion. These systems hold particular interest for mimicking biological phenomena, such as some aspects of cell locomotion collective behaviors bacterial colonies, well the design droplet-based biologically inspired materials, engineered tissues. Growing evidence suggests...

Regulation of dendritic spine motility was studied in dissociated cultures of the rat and mouse hippocampus, using green fluorescent protein-labeled neurons or neurons loaded with the calcium-sensitive dye Oregon Green-1. Cells were time-lapse-photographed on a confocal laser-scanning microscope at high resolution to detect movements as well as spontaneous fluctuations of intracellular calcium ...
