Anisotropy of small-scale stratospheric irregularities retrieved from scintillations of a double star α-Cru observed by GOMOS/ENVISAT [PDF]

open access: yesAtmospheric Measurement Techniques, 2012
In this paper, we discuss estimating anisotropy of air density irregularities (ratio of characteristic horizontal and vertical scales) from satellite observations of bi-chromatic scintillations of a double star whose components are not resolved by the ...

Color contributes to object-contour perception in natural scenes [PDF]

open access: yes, 2017
The magnitudes of chromatic and achromatic edge contrast are statistically independent and thus provide independent information, which can be used for object-contour perception.

Deep learning virtual colorization overcoming chromatic aberrations in singlet lens microscopy

open access: yes, 2021
Singlet lenses are free from precise assembling, aligning, and testing, which are helpful for the development of portable and low-cost microscopes. However, balancing the spectrum dispersion or chromatic aberrations using a singlet lens made of one ...

Universal Chromatic Resin-Based Composites: Aging Behavior Quantified by Quasi-Static and Viscoelastic Behavior Analysis

open access: yesBioengineering, 2022
Universal chromatic dental resin-based composites were recently developed in an attempt to speed up the restoration process with the aim of making it easier for the practitioner to decide on a suitable shade and to avoid time-consuming matching and ...

A Monitoring Campaign for Luhman 16AB. I. Detection of Resolved Near-Infrared Spectroscopic Variability [PDF]

open access: yes, 2013
[abbreviated] We report resolved near-infrared spectroscopic monitoring of the nearby L dwarf/T dwarf binary WISE J104915.57-531906.1AB (Luhman 16AB), as part of a broader campaign to characterize the spectral energy distribution and temporal variability

Intricate visibility effects from resolved emission of young stellar objects: the case of MWC158 observed with the VLTI [PDF]

open access: yes, 2012
In the course of our VLTI young stellar object PIONIER imaging program, we have identified a strong visibility chromatic dependency that appeared in certain sources.

Triangle-free geometric intersection graphs with large chromatic number [PDF]

open access: yes, 2013
Several classical constructions illustrate the fact that the chromatic number of a graph can be arbitrarily large compared to its clique number. However, until very recently, no such construction was known for intersection graphs of geometric objects in ...

An optical angle sensor based on chromatic dispersion with a mode-locked laser source

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
This paper proposes a new optical angle sensor, in which a mode-locked laser is employed as the light source, and chromatic dispersion of a collimator objective is utilized to detect the angular displacement of a target of interest.

Investigating neuromagnetic brain responses against chromatic flickering stimuli by wavelet entropies. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Photosensitive epilepsy is a type of reflexive epilepsy triggered by various visual stimuli including colourful ones. Despite the ubiquitous presence of colorful displays, brain responses against different colour combinations are not properly ...
