We propose a representation for efficiently and conveniently storing texture patches on surfaces without parameterization. The main purpose is to texture surfaces at very high resolution while using very little memory: patterns are stored once while instance (i.e., sprites) attributes (pattern number, size, orientation) are stored in an octree-like structure (requiring no surface parameterizati...

The success of mainstream computing is largely due to the widespread availability of general-purpose architectures and of generic approaches that can be used to solve real-world problems cost-effectively and across a broad range of application domains. In this chapter, we propose that a similar generic framework is used to make the development of autonomic solutions cost effective, and to estab...

This essay has two goals. The first is to define the behavioristic study of natural events and to classify behavior. The second is to stress the importance of the concept of purpose. Given any object, relatively abstracted from its surroundings for study, the behavioristic approach consists in the examination of the output of the object and of the relations of this output to the input. By outpu...

My research interest lies in the area of arithmetic geometry related to Langlands correspondence, where the theory of automorphic forms and algebraic geometry intersect. It is one of the most interesting and actively studied subject of algebraic number theory, whose origin goes back to the theory of complex multiplication. My research is currently focused on the local aspect of this theory, nam...

As a medical oncologist-researcher, I am often asked ‘How (or why) did you go into cancer?’ and ‘Isn’t it a depressing field?’ The answer to the second question is a resounding ‘no’, and this brief profile charts my path to answer the first question. Born and raised in Denver, Colorado, I am the daughter of two geologists, so ours was a scientific family. From an early age, my brother, sister a...

W hy is the sky blue? Any scientist will answer this question with a statement of mechanism: Atmospheric gas scatters some wavelengths of light more than others. To answer with a statement of purpose—e.g., to say the sky is blue in order to make people happy—would not cross the scientifi c mind. Yet in biology we often pose " why " questions in which it is purpose, not mechanism, that interests...
