The focus of this paper is on pointing gestures that do not function as deictic pointing to a concrete referent but rather as structuring the flow of information. Examples are given on their use in giving feedback and creating a common ground in natural conversations, and their meaning is described with the help of semantic themes of the Index Finger Extended gesture family. A communication mod...

We briefly review attempts to construct string theories that yield the standard model, concentrating on models with a geometric interpretation. Calabi-Yau compactifications are discussed in the context of both the weakly coupled heterotic string and the strongly coupled version, heterotic M-theory. Similarly, we consider orbifold compactifications of weakly coupled heterotic theory and of Type ...

This paper presents a brief review of our recent work investigating a novel bottom-up approach to realize silicon-based nanoelectronics. We discuss fabrication technique, electronic properties, and device applications of silicon nanodots as a building block for various nanoscale silicon devices. r 2006 Published by Elsevier Ltd.

The magnetostratigraphy of Sites 748 and 750 of Ocean Drilling Program Leg 120 is reported. About 260 sediment cubes were stepwise demagnetized with alternating fields to determine their characteristic direction of natural remanent magnetization. In general, the characteristic inclinations of the single samples have values similar to the inclination values obtained from whole-core measurements ...

A definition of distance measure between structural descriptions, which is based on a probabilistic interpretation of the matching predicate, is proposed. It aims at coping with the problem of classification when noise causes both local and structural deformations. The distance measure is defined according to a top-down evaluation scheme: distance between disjunctions of conjuncts, conjunctions...

Introduction Conclusions References

A comparative study across the most widely known blockchain technologies is conducted with a bottom-up approach. Blockchains are disentangled into building blocks. Each building block is then hierarchically classified in main and subcomponents. Then, alternative values (i.e., layouts) for the subcomponents are identified and compared between them. Finally, an ontology matrix summarises the stud...

The hypothesis that theories might influence observation was proposed in the important early work of Hanson (1958) and Kuhn (1962). It has been brought to a new focus by the interchanges between Fodor (1984, 1988) and Churchland (1979, 1988). Fodor has argued that perception is not cognitively penetrable, while Churchland has argued for a strong form of theory-Iadenness. This issue has led to v...
