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 ...

Modeling chromatic emittance growth in staged plasma wakefield acceleration to 1 TeV using nonlinear transfer matrices

open access: yesPhysical Review Accelerators and Beams, 2021
A framework for integrating transfer matrices with particle-in-cell simulations is developed for TeV staging of plasma wakefield accelerators. Using nonlinear transfer matrices in terms up to ninth order in normalized energy spread sqrt[⟨δγ^{2}⟩] and ...

Evaluation of various drying approaches on the physicochemical properties, rehydration kinetics, mathematical modeling and quality of tiger nut (Cyperus esculentum)

open access: yesJournal of Agriculture and Food Research, 2023
In this study, the quality and physicochemical properties as well as rehydration kinetics of dried tiger nuts were examined in relation to four different drying techniques.

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.

A Random Forest Algorithm for Landsat Image Chromatic Aberration Restoration Based on GEE Cloud Platform—A Case Study of Yucatán Peninsula, Mexico

open access: yesRemote Sensing, 2022
With the growth of cloud computing, the use of the Google Earth Engine (GEE) platform to conduct research on water inversion, natural disaster monitoring, and land use change using long time series of Landsat images has also gradually become mainstream ...

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 ...

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.

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 ...

Colour Vision and Chromaticity Scales [PDF]

open access: yesNature, 1940
IN a recent issue of NATURE1, Dr. W. D. Wright has given a very clear and interesting account of recent work in the direction of commercially practical application of measurement in the matching of colours, and in their analysis or synthesis. On the practical side the first steps were taken independently by Helmholtz and Maxwell in the employment of ...

Verdi’s six-fours and la parola scenica [PDF]

open access: yes, 2017
Verdi’s operas display many non-normative six-four chords. The question for the opera analyst, however, is not only what occurs musically, but why it does. Is there a dramatic function being served by this mix of harmonic-intervallic instability?
