A trial fibrillation (AF) is the most common cardiac arrhythmia. The preferred therapy for AF is sustained sinus rhythm control; however, the efficacy of currently used antiarrythmic drugs is limited by adverse side effects resulting from both a lack of ion channel selectivity and nonspecific ventricular activity. The role of the voltage-gated potassium channels in atrial myocyte repolarization...

In this work we investigate how two autonomous agent swarms, controlled by the BEECLUST algorithm are able to cooperate. The task is to locate two different target areas, which are located near each other. Therefore we developed an individual-based NetLogo model to simulate two different agent swarms moving in a temperature gradient. Both agent swarms are controlled by the BEECLUST algorithm, w...

Earthquake swarms observed before the 2006 and 2011 Nyamuragira eruptions were analysed. The activitiesand hypocenter distributions of these earthquake swarms were mainly examined.The former swarm was characterised by a higher seismic activity than the later. Although the two swarmsaccompanied eruptions, most of the swarms observed in 2006 and 2011 were not followed by any eruptions...

An alternative to deploying a single robot of high complexity can be to utilize robot swarms comprising large numbers of identical, and much simpler, robots. Such swarms have been shown to be adaptable, fault-tolerant and widely applicable. However, designing individual robot algorithms to ensure effective and correct overall swarm behaviour is actually very difficult. While mechanisms for asse...

We consider swarms as systems with partial random synchronicity and look at the conditions for their convergence to a fixed point. The conditions turn out to be not much more stringent than for linear, one-step, stationary iterative schemes, either synchronous or sequential. The rate of convergence is also comparable. The main result is that swarms converge in cases when synchronous and/or sequ...

Most research into Swarm Intelligence explores swarms of autonomous robots or simulated agents. Little work, however, has been done on swarms of networked humans. This paper introduces UNU, an online platform that enables networked users to assemble in real-time swarms and tackle problems as an Artificial Swarm Intelligence (ASI). Modeled after biological swarms, UNU enables large groups of net...

Much has been written concerning the use of raiding swarms of army ants by Neotropical birds in lowland forests. Bird-ant foraging associations are much less common at higher (subtropical) elevations, and no highland species have been identified as professional or regular ant-followers. All known professional army ant followers in the Neotropics occur below 1000 meters elevation (Ridgely & Tudo...

It is now more than 50 years since, in 1927, Sydney Campbell Dyke banded together the growing number of pathologists to form the British Pathologists' Association, which later became known as The Association of Clinical Pathologists. Dyke had a wide-ranging interest in medicine, unlike some of his successors, who have relinquished their clinical affiliations and have retired to the confines of ...
