The ambiguities due to the purely syntactical nature of MPEG7 have hindered its widespread application as they lead to serious interoperability issues in sharing and managing multimedia metadata. Acknowledging these limitations, a number of initiatives have been reported towards attaching formal semantics to the MPEG-7 specifications. In this paper we examine the rationale on which the relevant...

The paper introduces a new concept of intrinsic risk attitude. In contrast to the common Arrow-Pratt measure, the present concept is directly tied to preferences on the multidimensional consumption space and is independent of the way we measure consumption, of the commodity under observation, and of market prices or liquidity constraints. The measure relies on intertemporal choice to distinguis...

BYOD policies are informally specified using natural language. We show how the SP4BYOD language can help reduce ambiguity in 5 BYOD policies and link the specification of a BYOD policy to its implementation. Using a formalisation of the 5 policies written in SP4BYOD, we make comparisons between them, and explore the delegation relationships within them. We identify that whilst policy acknowledg...

Natural products are universally recognized to contribute valuable chemical diversity to the design of molecular screening libraries. The analysis undertaken in this work, provides a foundation for the generation of fragment screening libraries that capture the diverse range of molecular recognition building blocks embedded within natural products. Physicochemical properties were used to select...

Evolutionary biologists from Darwin forward have dreamed of having data that would elucidate our understanding of evolutionary history and the diversity of life. Sequence capture is a relatively old DNA technology, but its use is growing rapidly due to advances in (i) massively parallel DNA sequencing approaches and instruments, (ii) massively parallel bait construction, (iii) methods to identi...

Although product line architectures serve an increasingly important role in the software development process, no representation currently exists in which they can be precisely captured. This position paper presents our work to date in addressing this problem. Specifically, we introduce a novel representation that can be used to specify the details of a product line architecture. The representat...

This is a golden age for ion channels: a time when chemistry, molecular biology, and electrophysiology have come together with structural biology to provide glimpses into some truly amazing membrane proteins. And yet, as usual, the answers yield more questions. Is a new structure the structure of an open channel or of a closed one? How does the voltage sensor actually move? Though providing ama...

8 were performed by Mark Sussman, see ref 29], 30]. The algorithm is based on the level set method and is quite simple to implement. It should be stressed that no special work is needed at pinchoo, merging, development of kinks, etc. and the algorithm is very easy to implement on a xed, uniform grid. All these gures should be read left to right, top to bottom. Figure 1 shows the evolution of a ...
