The Proto spatial computing language [1] simplifies the creation of scalable, robust, distributed programs by abstracting a network of locally communicating devices as a continuous geometric manifold. However, Proto’s successful application in a number of domains is challenging its coherence across different platforms and distributions. We thus present a complete operational semantics for the P...

Studies in 14 patients with unconjugated hyperbilirubinaemia caused by Gilbert's syndrome have revealed abnormalities of the enzymes of haem biosynthesis measured in peripheral blood cells. The activity of the penultimate enzyme of haem biosynthesis protoporphyrinogen (PROTO) oxidase was reduced at 3.1 +/- 2.6 nmol PROTO/g protein/h (mean +/- ISD) compared with 8.2 +/- 5.1 in controls (p less t...

In comparing deliberation to the analysis of a geometrical figure, Aristotle made a highly significant theoretical statement on design, which has largely gone unnoticed. Through an interpretation of the accounts given by Aristotle and the Greek geometer Pappus, seven features of the method of analysis can be identified, concerning the types of analysis, its stages, its start and end points, the...

Image salient object detection is useful for applications like image retrieval, object recognition etc. Aiming to obtain the pixel-level saliency map, most traditional saliency models ignore the object-level information and become inappropriate in complex scenes. A new salient object detection method is proposed in this paper by incorporating the notion of object and background prior directly i...

We consider a simple information-theoretic model for evolutionary dynamics approaching the "coding threshold," where the capacity to symbolically represent nucleic acid sequences emerges in response to a change in environmental conditions. We study the conditions when a coupling between the dynamics of a "proto-cell" and its proto-symbolic representation becomes beneficial in terms of preservin...
