Forward Global Photometric Calibration of the Dark Energy Survey [PDF]

open access: yes, 2017
Many scientific goals for the Dark Energy Survey (DES) require calibration of optical/NIR broadband $b = grizY$ photometry that is stable in time and uniform over the celestial sky to one percent or better.

Aspects of Villa-Lobos’s Tonal Style in Some of His Studies for Guitar

open access: yesRevista Vortex, 2020
The goal of this paper is to shed new light on selected strategies that characterize the tonal style of the first nine studies of the set by means of examining Villa- Lobos’s treatment of tonality from a perspective that takes into account the role of ...

Sex-related differences in chromatic sensitivity [PDF]

open access: yes, 2008
Generally women are believed to be more discriminating than men in the use of colour names and this is often taken to imply superior colour vision. However, if both X-chromosome linked colour deficient males (~8%) and females (

Calibration and removal of lateral chromatic aberration in images [PDF]

open access: yes, 2007
This paper addresses the problem of compensating for lateral chromatic aberration in digital images through colour plane realignment. Two main contributions are made: the derivation of a model for lateral chromatic aberration in images, and the ...

Development of coloring alloys: Color design for lightweight Al-Mg-Si alloys

open access: yesMaterials & Design, 2021
Here, novel lightweight Al alloys were designed with an objective to achieve diverse color range and improved mechanical properties. The alloy design strategy was based on a scientific color expression method controlling the microstructural attributes ...

Luminance cues constrain chromatic blur discrimination in natural scene stimuli [PDF]

open access: yes, 2013
Introducing blur into the color components of a natural scene has very little effect on its percept, whereas blur introduced into the luminance component is very noticeable.

An optimized method for 3D fluorescence co-localization applied to human kinetochore protein architecture

open access: yeseLife, 2018
Two-color fluorescence co-localization in 3D (three-dimension) has the potential to achieve accurate measurements at the nanometer length scale. Here, we optimized a 3D fluorescence co-localization method that uses mean values for chromatic aberration ...
