Coherent detection of partially coherent sources
Optics Letters, 1980The mean square of the beating component of the photodetector output current of a coherent optical or infrared receiver, illuminated by partially coherent quasi-monochromatic radiation, is expressed in terms of the mutual intensity functions of the signal and local reference fields on the detector’s active surface.

Soulevant le probleme de la justification du jugement de coherence et du prix a payer en ce qui concerne sa relation a la realite, l'A. examine la notion comparative de coherence dans le domaine de l'interet, a travers l'analyse des contraintes du choix developpee par P. Thagard et K. Verbeurgt.

Science, 2000
A principal aim of current conservation policy is to reduce the impact of habitat fragmentation. Conservation corridors may achieve this goal by facilitating movement among isolated patches, but there is a risk that increased connectivity could synchronize local population fluctuations (causing coherent oscillations) and thereby increase the danger of ...

Ergodic Theory and Dynamical Systems, 2003
Summary: A partially hyperbolic diffeomorphism is dynamically coherent if its center, center-stable and center-unstable invariant distributions are integrable, i.e. tangent to foliations. Dynamical coherence is a key assumption in the theory of stable ergodicity.

Coherent and thermal coherent state
Journal of Mathematical Physics, 1989The characterization of coherent states as the quantum states that split into two uncorrelated beams is considered. The characterization leads to the study of coherent states at finite temperature—thermal coherent states (TCS’s). These TCS’s are defined within the formalism of thermo field dynamics (TFD).

Subsumption used in subtyping breaks the term-as-proofs paradigm. Semantics most naturally are associated with proofs. Thus a problem of coherence arises: different typing proofs of the same term must have related meanings. We propose a proof-theoretical, rewriting approach to this problem.

Erkenntnis, 1999
The article advocates a particular coherence theory of justification that emphasizes the significance of explanatory relations. It is shown that other approaches to coherence have failed because they underestimate the importance of explanatory theories in forming a system of beliefs.

Coherence in conversations and in texts can be partially characterized by a set of coherence relations, motivated ultimately by the speaker's or writer's need to be understood. In this paper, formal definitions are given for several coherence relations, based on the operations of an inference system; that is, the relations between successive portions ...
