In this contribution we report on a transition to high-dimensional chaos through three-frequency quasiperiodic behavior. The resulting chaotic attractor has a one positive and two null Lyapunov exponents. The transition occurs at the point at which two symmetry related threedimensional tori merge in a crisis-like bifurcation. The route can be summarized as: 2D torus → 3D torus→ high-dimensional...

A novel crystal timing calibration method based on total variation (TV), abbreviated as 'TV merge', has been developed for a high-resolution positron emission tomography (PET) system. The proposed method was developed for a system with a large number of crystals, it can provide timing calibration at the crystal level. In the proposed method, the timing calibration process was formulated as a li...

1 Computation with doubling constituents: Pronouns and antecedents in Phase Theory Sandiway Fong Jason Ginsburg University of Arizona University of Aizu Abstract In the biolinguistics program, syntax has access to only limited and minimal operations such as Merge (and Move) plus local (to Phase) probe-goal, Chomsky (2000, 2001). Under this blueprint, the challenge for implementation is twofold:...

STM (Software Transactional Memory) systems can be used to speculatively parallelize irregular applications such as those based on graphs and trees. While the transactional paradigm is suitable for such speculative parallelization, STMs do not deal with the semantics of speculation. In this paper we introduce merge semantics for speculations. STMs optimistically execute code and monitor the exe...

A recent study of a child born with one cerebral hemisphere has revealed an extreme developmental reorganization of visual cortex. Self-organizing visual maps demonstrate a surprisingly flexible restructuring in response to cortical loss.

This paper investigates merge-in-transit as an approach to reengineering assembly, warehouse and billing processes for electronic commerce. Merge-in-transit is de®ned and some examples are given to illustrate its use. Processes necessary to accomplish merge-in-transit are developed, while advantages and disadvantages of merge-in-transit are studied. Additional issues arising from merge-in-trans...
