Partially coherent sources with circular coherence [PDF]
Optics Letters, 2017 A new class of partially coherent light sources is introduced. At the source plane, they exhibit perfect coherence along any annulus that is concentric to the source center. Between two points at different distances from the center, coherence can be partial or even vanishing.

Single-cycle surface plasmon polaritons on a bare metal wire excited by relativistic electrons
Nature Communications, 2016 Here, the authors demonstrate how ultra-short bunches of relativistic electrons produce coherent transition radiation at the tip of a thin wire. The radiation then propagates as a powerful surface plasmon polariton along the wire, illustrating the ...

Quantum Information Processing, 2019 The concept of entanglement fraction is generalized to define coherence fraction of a quantum state. Precisely, it quantifies the proximity of a quantum state to maximally coherent state and it can be used as a measure of coherence. Coherence fraction has a connection with $l_1$-norm coherence and provides the criteria of coherence distillability ...

Methods in Ecology and Evolution, 2023 Vegetation canopy height is a relevant proxy for aboveground biomass, carbon stock, and biodiversity. Wall‐to‐wall information of canopy height with high spatial resolution and accuracy is not yet available on large scales.

Why There Cannot be a Single Probabilistic Measure of Coherence [PDF]
, 2005 Bayesian Coherence Theory of Justification or, for short, Bayesian Coherentism, is characterized by two theses, viz. (i) that our degree of confidence in the content of a set of propositions is positively affected by the coherence of the set, and (ii ...

Studia Logica, 2002 Coherence is demonstrated for categories with binary products and sums, but without the terminal and the initial object, and without distribution. This coherence amounts to the existence of a faithful functor from a free category with binary products and sums to the category of relations on finite ordinals.

Structural Dynamics, 2018 The possibility to perform high-resolution time-resolved electron energy loss spectroscopy has the potential to impact a broad range of research fields. Resolving small energy losses with ultrashort electron pulses, however, is an enormous challenge due ...

Time-of-flight electron energy loss spectroscopy using TM110 deflection cavities
Structural Dynamics, 2016 We demonstrate the use of two TM110 resonant cavities to generate ultrashort electron pulses and subsequently measure electron energy losses in a time-of-flight type of setup.

Beyond the Features: The Role of Consistency in Impressions of Trust
Social Psychological Bulletin, 2022 To be successful in social life, perceivers need to form impressions of other people's trustworthiness. Current models of this process emphasize the role of specific descriptive content–individual verbal and visual features determining trust impressions.

COHERENCE AND ELICITABILITY [PDF]
Mathematical Finance, 2014 The risk of a financial position is usually summarized by a risk measure. As this risk measure has to be estimated from historical data, it is important to be able to verify and compare competing estimation procedures. In statistical decision theory, risk measures for which such verification and comparison is possible, are called elicitable.
