Movement on surfaces, or swarming motility, is effectively mediated by the lateral flagellar (laf) system in Vibrio parahaemolyticus. Expression of laf is induced by conditions inhibiting rotation of the polar flagellum, which is used for swimming in liquid. However, not all V. parahaemolyticus isolates swarm proficiently. The organism undergoes phase variation between opaque (OP) and transluce...

Boid flocking is a system in which several individual agents follow three simple rules to generate swarm-level flocking behavior. To control this system, the user must adjust the agent program parameters, which indirectly modifies the flocking behavior. This is unintuitive because the properties of the flocking behavior are nonexplicit in the agent program. In this paper, we discuss a domain-in...

We simulate the swarming behavior of three synthetic animal species that differ only by the degree of perception they have on their fellow animals. The species are called mosquitoes, birds and fish. The swarms that comprise many individuals of each species in turn move randomly in a rugged potential landscape. The mosquitoes pay no heed to one another. The birds follow a bunch of their nearest ...

Motion is a common phenomenon in biological processes. Major advances have been made in designing various self-propelled micromachines that harvest different types of energies into mechanical movement to achieve biomedicine and biological applications. Inspired by fascinating self-organization motion of natural creatures, the swarming or assembly of synthetic micro/nanomachines (often referred ...

Many mathematical models, which try to capture emergent phenomena, are based on state transitions that depend on neighborhood relationships. Cellular Automata (CA) and Random Boolean Networks (RBN) are examples of such models, where connectivity patterns determine the flow of signals among interconnected units. Whereas neighborhoods in CA and RBNs remain static, the focus of our investigations ...

An association between swarming and hemolysin BL secretion was observed in a collection of 42 Bacillus cereus isolates (P=0.029). The highest levels of toxin were detected in swarmers along with swarm cell differentiation (P=0.021), suggesting that swarming B. cereus strains may have a higher virulence potential than nonswarming strains.

Research on swarming has primarily focused on applying swarming behavior with physics-derived or ad-hoc models to tasks requiring collective intelligence in robotics and optimization. In contrast, applications in signal processing are still lacking. The purpose of this paper is to investigate the use of biologically-inspired swarm methods for signal filtering. The signal, in the case of images ...

This paper presents a framework for decentralized control of self-organizing swarm agents based on the artificial potential functions (APFs). The framework explores the benefits by associating agents based on position information to realize complex swarming behaviors. A key development is the introduction of a set of association rules by APFs that effectively deal with a host of swarming issues...

Swarming behaviours in animals have been extensively studied owing to their implications for the evolution of cooperation, social cognition and predator-prey dynamics. An important goal of these studies is discerning which evolutionary pressures favour the formation of swarms. One hypothesis is that swarms arise because the presence of multiple moving prey in swarms causes confusion for attacki...

We consider the issues of applying the universal swarming technique to transfer massive content efficiently. In a swarming session, a file is distributed to all the receivers by having all the nodes in the session exchange file chunks. By universal-swarming, not only all the nodes in the session, but also some nodes outside the session may participate in the chunk exchange to speed up the distr...
