The ciliate Tetrahymena thermophila is a model organism for molecular and cellular biology. Like other ciliates, this species has separate germline and soma functions that are embodied by distinct nuclei within a single cell. The germline-like micronucleus (MIC) has its genome held in reserve for sexual reproduction. The soma-like macronucleus (MAC), which(More)
A k ey diiculty in the design of multi-agent robotic systems is the size and complexity of the space of possible designs. In order to make principled design decisions, an understanding of the many possible system conngurations is essential. To this end, we present a taxonomy that classiies multi-agent systems according to communication, computational and(More)
BACKGROUND Ichthyophthirius multifiliis, commonly known as Ich, is a highly pathogenic ciliate responsible for 'white spot', a disease causing significant economic losses to the global aquaculture industry. Options for disease control are extremely limited, and Ich's obligate parasitic lifestyle makes experimental studies challenging. Unlike most(More)
W e quantify the observation by Kender and Freudenstein [6] that degenerate views occupy a significant fraction of the viewing sphere surrounding an object. This demonstrates that systems for recognition must explicitly account f o r the possibility of view degeneracy. W e show that view degeneracy cannot be detected from a single camera viewpoint. As a(More)
Dynein is the large molecular motor that translocates to the (-) ends of microtubules. Dynein was first isolated from Tetrahymena cilia four decades ago. The analysis of the primary structure of the dynein heavy chain and the discovery that many organisms express multiple dynein heavy chains have led to two insights. One, dynein, whose motor domain(More)
This paper deals with coordinating behaviour in a multi-autonomous robot system. When two or more autonomous robots must interact in order to accomplish some common goal, communication between the robots is essential. Diierent inter-robot communications strategies give rise to diierent overall system performance and reliability. After a brief consideration(More)
The ARK mobile robot project has designed and implemented a series of mobile robots capable of navigating within industrial environments without relying on ar-tiicial landmarks or beacons. The ARK robots employ a novel sensor, Laser Eye, that combines vision and laser ranging to eeciently locate the robot in a map of its environment. Laser Eye allows(More)
