Ascorbic acid content and transcriptional profiling of genes involved in its metabolism during development of petals, leaves, and fruits of orange (C…

2021

Citrus fruit is one of the most important contributors to the ascorbic acid (AsA) intake in humans. Here, we report a comparative analysis of AsA content and transcriptional changes of genes related to its metabolism during development of petals, leaves and fruits of Valencia Late oranges (Citrus sinensis). Petals of close flowers and at anthesis contained the highest concentration of AsA. In fruits, AsA content in the flavedo reached a maximum at color break, whereas the pulp accumulated lower levels and experienced minor fluctuations during development. AsA levels in leaves were similar to those in the flavedo at breaker stage. The transcriptional profiling of AsA biosynthetic, degradatio…

Architectural Representation: a Tool for Urban Regeneration : the Colour Plan of Egadi Islands

2018

The Egadi Islands, at the western end of Sicily, preserve a peculiar architectural and environmental heritage. The work of people – related to tuna fishing, stone extraction and agriculture – has created, over time, an exceptional landscape. The nature, colour and texture of the local stone have given shape to a traditional architecture that, today, risks to disappear and to be replaced by new anonymous buildings. Furthermore, the pressure of tourism threatens to damage this delicate balance established, over centuries, between people and environment. Therefore, the Local Administration decided to adopt a Colour Plan to manage the inevitable processes of territorial transformations. The Arc…

Colour image segmentation and labeling through multiedit-condensing

1992

Abstract A new method is proposed for detecting and locating objects of interest within a colour scene under very strong variabilities in lighting conditions, object shape and pigmentation. The method is based on Nearest Neighbour classification and Multiedit-Condensing techniques and is applied to implement the vision subsystem of a robotic citric harvesting device. Experiments and results are reported showing the effectiveness of the method and illustrating its appropriateness to the proposed task.

THE INFLUENCE OF CHROMATIC ABERRATION ON DEMOSAICKING

2014

International audience; The wide deployment of colour imaging devices owes much to the use of colour filter array (CFA). A CFA produces a mosaic image, and normally a subsequent CFA demosaick-ing algorithm interpolates the mosaic image and estimates the full-resolution colour image. Among various types of optical aberrations from which a mosaic image may suffer, chromatic aberration (CA) influences the spatial and spectral correlation through the artefacts such as blur and mis-registration, which demosaicking also relies on. In this paper we propose a simulation framework aimed at an investigation of the influence of CA on demosaicking. Results show that CA benefits de-mosaicking to some ex…

Briganti, Longhi und «La Maniera italiana» (1961)

2022

Due inedite testimonianze di Giuliano Briganti e Roberto Longhi gettano luce sul ruolo che lo storico dell'arte assume tanto nella fase di raccolta del materiale iconografico, quanto nella definizione della 'temperatura' del colorito durante la fase di stampa. Il Manierismo, così come si presenta nel volume che Briganti pubblica nel 1961 con Editori Riuniti (Roma) e Verlag der Kunst (Dresden), è un'avanguardia decadentista dal cromatismo inquietante e freddo. Two previously unpublished testimonies by Giuliano Briganti and Roberto Longhi shed light on the role of the art historian in both the collection of iconographic material and the definition of the 'temperature' of colour during the pri…

Best not to bet on the horserace: A comment on Forrin and MacLeod (2017) and a relevant stimulus-response compatibility view of colour-word contingen…

2018

International audience; One powerfully robust method for the study of human contingency learning is the colour-word contingency learning paradigm. In this task, participants respond to the print colour of neutral words, each of which is presented most often in one colour. The contingencies between words and colours are learned, as indicated by faster and more accurate responses when words are presented in their expected colour relative to an unexpected colour. In a recent report, Forrin and MacLeod (2017b, Memory & Cognition) asked to what extent this performance (i.e., response time) measure of learning might depend on the relative speed of processing of the word and the colour. With keypr…

¿Qué pueden aportar las ciencias de la visión al diseño gráfico?

2020

[ES] El diseño gráfico es importante y necesario en el mundo de hoy porque la vista es la principal forma de adquisición de información. Por lo tanto, es lógico pensar que las ciencias de la visión pueden ayudar en la toma de decisiones a nivel de diseño. Comprender conceptos como la agudeza visual, la sensibilidad al contraste, entre otros, contribuirá a optimizar la legibilidad del texto a través de una selección óptima de parámetros tipográficos para formatos impresos y digitales. Además, entender el efecto de las diferentes alteraciones en la visión del color mejorará la accesibilidad del diseño.

Liberate the form. White concrete in the work of Álvaro Siza

2022

The study of the extensive work of Álvaro Siza Vieira allows relating the progressive linguistic innovation and the spatial experimentation of his architecture with the use of different constructive techniques and technologies. Assuming the white colour as the guiding thread of the discourse, the professional trajectory of Siza is traversed from its initial link with the Portuguese architectural tradition of the early twentieth century, until the current adoption of the constructive principles of the exposed concrete. The contribution puts in perspective some recent works of the Portuguese master, ordering and analyzing the projects with the aim of elucidating the underlying architectural p…
