The structure of binary coproducts in the category of frames is analyzed, and the results are then applied widely in the study of compactness, local compactness (continuous frames), separatedness, pushouts and closed frame homomorphisms.

Research across numerous domains has highlighted the current--and presumably temporary--effects of frames on preference and behavior. Yet people often encounter information that has been framed in different ways across contexts, and there are reasons to predict that certain frames, once encountered, might tend to stick in the mind and resist subsequent reframing. We propose that loss frames are...

In this work, we give a description of the process of teleportation between Alice in an inertial frame, and Rob who is in uniform acceleration with respect to Alice. The fidelity of the teleportation is reduced due to Davies-Unruh radiation in Rob's frame. In so far as teleportation is a measure of entanglement, our results suggest that quantum entanglement is degraded in noninertial frames.

We characterize L norms of functions on R for 1 < p < ∞ in terms of their Gabor coefficients. Moreover, we use the Carleson-Hunt theorem to show that the Gabor expansions of L functions converge to the functions almost everywhere and in L for 1 < p < ∞. In L we prove an analogous result: the Gabor expansions converge to the functions almost everywhere and in L in a certain Cesàro sense. Consequ...

We employ moving frames along pairs of curves at constant separation to derive various conditions for a curve to belong to the surface of a circular cylinder.

OBJECTIVES Egocentric coordinate systems centred on the trunk, head, and gaze have been investigated in a patient who displays severe extrapersonal neglect and in five control subjects. METHODS The subjects were tested with a blind tactile exploration task in five different experimental conditions in which the role of the three distinct frames of reference was individually controlled. RESUL...

We use a three-dimensional massive field theory up to the two-loop approximation to study the critical behavior of semi-infinite quenched random Ising-like systems at the special surface transition. Besides, we extend up to the next-to leading order, the previous first-order results of the sqrt[epsilon] expansion obtained by Ohno and Okabe [Phys. Rev. B 46, 5917 (1992)]. The numerical estimates...

An integrated framework for automatic extraction of the most characteristic frames or scenes of a video sequence is presented in this paper. This is accomplished by extracting a collection of a small number of frames or scenes that provide sufficient information about the video sequence. The scene/frame selection mechanism is based on a transformation from the image to a feature domain, which i...

The EPR-Observatory--a public funded project organization--has monitored Danish EPR-projects with respect to various parameters such as diffusion and diffusion rate, barriers and limitations, experience gained. Furthermore, the Observatory has aggregated and disseminated the results and has established a constructive dialogue between the Danish EPR projects. The Observatory has also focused in ...
