The use of the term \landscape" is increasing rapidly in the eld of evolutionary computation, yet in many cases it remains poorly, if at all, deened. This situation has perhaps developed because everyone grasps the imagery immediately, and the questions that would be asked of a less evocative term do not get asked. This paper presents an important consequence of a new model of landscapes. The m...

It is a fundamental fact about simultaneous linear equations that uniqueness implies existence in the sense that if the »X» system MX= Y has, for each Y, at most one solution X, then, for each Y, the equation actually has a solution. Our purpose is to show that this situation persists for certain "nonlinear equations" as well, namely that, restricting everything to the reals, if Pi, P2 are poly...

"One Acupuncture", like "One Medicine", has the potential to improve research quality and clinical outcomes. However, while human acupuncture point locations have remained largely consistent over time, the veterinary versions remain imprecise and variable. Establishing anatomical criteria for veterinary acupuncture atlases in keeping with the human template will create congruence across species...

There is, therefore, a need for greater integration and coordination between medical researchers and practitioners, and researchers and practitioners involved in both domestic and wild animal health. This integration has been defined as the ‘One Health’ approach and is an approach that has taken hold in many developing countries where infectious diseases remain prevalent, but less so in develop...

Reversible computation is a great metaphor for the foundations of physics. General discussion A reversible computation is a computation which can be reversed completely. That is, after insertion of the input into a reversible computer, the reversible computer generates some output (if ever). In such a case one may run the entire computation backward by inserting the output as new input, thereby...

The notion that humans, animals and the environment are tightly linked and that their respective well-beings are interdependent has been recognized for centuries. However, the sophistication of these interactions has only begun to be revealed. Even by the late nineteenth century, it was established knowledge that human and animal health have many commonalities; an insight that more recently led...

184 NOTICES OF THE AMS VOLUME 51, NUMBER 2 Introduction The classification of closed surfaces is a milestone in the development of topology, so much so that it is now taught to most mathematics undergraduates as an introduction to topology. Since the solution of the uniformization problem for surfaces by Poincaré and Koebe, this topological classification is now best understood in terms of the ...

Let S be the standard class of univalent functions in the unit disk, and let So be the class of nonvanishing univalent functions g with g(0) = 1. It is shown that the regions of variability {g(r): g £ So} and {(1 — r2)f'(r) : f £ S} are very closely related but are not quite identical. Let 5 be the class of functions / analytic and univalent in the unit disk D, with /(0) = 0 and /'(O) = 1. Let ...

In a discussion of (Juola and Plunkett, 2000), (Thomas and de Wet, 1998) argue that the apparent double dissociations found in that study simply show that the backpropagation network used did not have enough hidden units and that the network did (or could) not develop “fully distributed internal representations.” In other words, the dissociations found were, in their opinion, probably not just ...
