The microbiology of Lascaux Cave.
2010
Lascaux Cave (Montignac, France) contains paintings from the Upper Paleolithic period. Shortly after its discovery in 1940, the cave was seriously disturbed by major destructive interventions. In 1963, the cave was closed due to algal growth on the walls. In 2001, the ceiling, walls and sediments were colonized by the fungus Fusarium solani. Later, black stains, probably of fungal origin, appeared on the walls. Biocide treatments, including quaternary ammonium derivatives, were extensively applied for a few years, and have been in use again since January 2008. The microbial communities in Lascaux Cave were shown to be composed of human-pathogenic bacteria and entomopathogenic fungi, the for…
Jay De Feo's Forgotten Roses: The Wise and Foolish Virgins
2009
in 2012–2013 the Whitney Museum of American Art will feature a retrospective exhibition of Jay De Feo's works. In view of this, it should be noted that two of her lesser-known monumental paintings ...
El monogramista F.D.V. ¿Frans de Vriendt? A propósito de una Susana y los viejos firmada y fechada en 1543
2017
En este artículo analizamos una pintura flamenca inédita, que representa la escena de Susana y los viejos. Se conserva en una colección particular de Cartagena (Murcia). Está fechada en 1543 y firmada por F.D.V., monograma que plantea la principal incógnita de nuestra investigación. Tales siglas hacen pensar de inmediato en el pintor Frans Floris de Vriendt. En este sentido, los rasgos estilísticos de la obra están próximos al espíritu de este maestro. Sin embargo, diversas cuestiones nos impiden confirmar por el momento tal autoría. En el texto desarrollamos estas hipótesis y definimos la personalidad artística del que denominamos Monogramista F.D.V. In this paper, we analyze an unpublishe…
Mathematical Models for Restoration of Baroque Paintings
2006
In this paper we adapt different techniques for image deconvolution, to the actual restoration of works of arts (mainly paintings and sculptures) from the baroque period. We use the special characteristics of these works in order to both restrict the strategies and benefit from those properties. We propose an algorithm which presents good results in the pieces we have worked. Due to the diversity of the period and the amount of artists who made it possible, the algorithms are too general even in this context. This is a first approach to the problem, in which we have assumed very common and shared features for the works of art. The flexibility of the algorithm, and the freedom to choose some…
Opere d’arte francescane dall’alto Belice corleonese alla Valle del Sosio
2013
Si analizzano opere d’arte, anche inedite, legate alla committenza francescana dell’alto Belice corleonese e della Valle del Sosio pubblicando documenti emersi nel corso della ricerca We analyze works of art, also unpublished, related to the Franciscan patronage of the Upper Belice Corleonese and the Sosio Valley by publishing documents that emerged during the research.
Face Inpainting via Nested Generative Adversarial Networks
2019
Face inpainting aims to repaired damaged images caused by occlusion or cover. In recent years, deep learning based approaches have shown promising results for the challenging task of image inpainting. However, there are still limitation in reconstructing reasonable structures because of over-smoothed and/or blurred results. The distorted structures or blurred textures are inconsistent with surrounding areas and require further post-processing to blend the results. In this paper, we present a novel generative model-based approach, which consisted by nested two Generative Adversarial Networks (GAN), the sub-confrontation GAN in generator and parent-confrontation GAN. The sub-confrontation GAN…
Complete karyotype characterization of the K562 cell line by combined application of G-banding, multiplex-fluorescence in situ hybridization, fluores…
2001
This study combines conventional cytogenetics, fluorescence in situ hybridization (FISH), multiplex-FISH and comparative genomic hybridization (CGH). In applying this multimodal approach on the human leukemia cell line K562, the chromosome composition was refined in detail and compared with data from the literature. A hypotriploid karyotype with a modal chromosome number of 67, and 21 unique marker chromosomes were identified. The classification of six markers was identical to published data and the composition of five further markers from the literature could be fully clarified for the first time. The composition of another five markers, which have been interpreted in divergent ways in dif…
Genetic aspects in hominid evolution
2000
Genomic comparison between apes and humans have made important contributions to our understanding of human evolution. The modern period of karyological comparisons between humans and other primates began about forty years ago and has been marked by a series of technical revolutions. In the 1960s pioneering genetic and chromosomal comparisons of human and great apes suggested, as had Darwin a century before, that our closest relative were the African apes. Early immunological analyses placed human/apes divergence at about five million year ago. Acceptance of man’s late divergence from the African apes was delayed by the scarcity of paleontological evidence coupled with a fallacious Asiatic o…
The impact of arthropods on fungal community structure in Lascaux Cave
2009
Aims: To determine the major components of the fungal population present in Lascaux Cave, France. The ceiling, walls, sediments and soil were colonized by Fusarium solani in 2001 and later, in 2006, black stains appeared. However, the origin of the successive fungal invasions is unknown as well as the ecology of the cave. Methods and Results: The primers nu-SSU-0817F and nu-SSU-1536R were used for the direct amplification of fungal 18S-rDNA sequences from 11 samples. A total of 607 clones were retrieved. Eight out of the ten most abundant phylotypes corresponded to fungi associated with arthropods and represented about 50% of the clones. Conclusions: Entomophilous fungi play an important ro…
Obesity in Aging and Art
2009
THIS issue of Journal of Gerontology: Medical Sciences highlights new findings on obesity in older persons and its consequences for health and function (1,2,3). The obesity epidemic is spreading rapidly in both developed and developing countries, and perspectives on the negative effects of overweight and obesity abound in recent medical literature. What do we know so far about obesity over the lifetime? Obesity does not spare older persons (4). Obese older persons experience a wide range of negative consequences, including metabolic abnormalities, arthritis, pulmonary diseases, cataracts, cancer, impaired mobility, disability, and mortality. Given the already extensive knowledge base, why a…
