Quelques éléments sur la vie et l'oeuvre de Robert d'Adhémar.
2010
Nous avons rassemblé dans cette note divers éléments sur la vie et les travaux scientifiques de Robert d'Adhémar. A notre connaissance, il n'existe pas de notice sur Robert d'Adhémar. Nous donnons quelques extraits de lettres écrites par Robert d'Adhémar à son ami, le mathématicien Robert de Montessus de Ballore.
Superficial Siderosis of the Central Nervous System associated with Hemophilia A: A case report
2021
Abstract Superficial Siderosis of the Central Nervous System (SSCNS) is a condition secondary to the deposition of hemosiderin within the subpial layers of central nervous system leading to its progressive degeneration, clinically responsible for hearing impairment, cerebellar ataxia and pyramidal syndrome. Here we report the case of a 61-year-old man with medical history of congenital hemophilia A presenting with typical clinical features of SSCNS associated with extensive hypo-intensity on fast 2D gradient-echo-weighted sequences, along the spinal cord, posterior fossa's structures and cerebral cortex. Interestingly, although his disorder was revealed by a lumbar spinal stenosis, presurgi…
Peripheral Calcifying Odontogenic Cyst : a rare case report
2018
The Calcifying Odontogenic Cyst (COC) is a simple cyst lined by ameloblastoma-like epithelium with ghost cells. The peripheral COC is a rare lesion and few reports have been published considering its clinical and histopathological features. This article aimed to report on a case of a peripheral COC, discussing its clinical, imaginological and histopathological features. A 9-year-old male patient presented a 10x5 mm painless nodule in the palatal mucosa of the left central incisor. Panoramic, occlusal and periapical radiographs did not show alterations. A computed tomography exam showed a slight soft tissue swelling located in the palatal mucosa of the left maxillary central incisor. An exci…

Aportaciones de la neurociencia cognitiva a la estimulación auditiva musical de 0 a 6 años
2016
Este artículo forma parte de una investigación más amplia acerca de la actitud y la aptitud que los maestros generalistas de 2º ciclo de Educación Infantil de los colegios públicos de Valencia tienen para estimular auditivamente a sus alumnos a partir de la discriminación auditiva y la escucha comprensiva de las audiciones musicales, con el fin de desarrollar el oído interno y la capacidad atencional. A lo largo de este trabajo se explica cómo afecta al cerebro infantil una continua estimulación sensorial, concretamente la auditiva, desde el ámbito neurológico
Morphological variability in and distributional data on phaleria bimaculata populations from islands of the central mediterranean area
2011
This study aimed to collect new taxonomic and distribution data on Phaleria bimaculata (L.) (Coleoptera Tenebrionidae) from Sicily (southern Italy), the circum-Sicilian islands and the Maltese archipelago. Particular attention was paid to the diagnostic morphological features observed in the populations sampled, focusing on the subspecies Phaleria bimaculata marcuzzii Aliquò. P. bimaculata individuals were collected from 20 different locations, of which 2 were located in the Sicilian mainland, 9 in circum-Sicilian islands and 9 in the Maltese Islands. In addition, four Phaleria acuminata Kuster populations were also recorded along southern Sicilian shores. The two Phaleria species were neve…
Correlation based networks of equity returns sampled at different time horizons
2006
We investigate the planar maximally filtered graphs of the portfolio of the 300 most capitalized stocks traded at the New York Stock Exchange during the time period 2001-2003. Topological properties such as the average length of shortest paths, the betweenness and the degree are computed on different planar maximally filtered graphs generated by sampling the returns at different time horizons ranging from 5 min up to one trading day. This analysis confirms that the selected stocks compose a hierarchical system progressively structuring as the sampling time horizon increases. Finally, a cluster formation, associated to economic sectors, is quantitatively investigated.
Wizerunek cudzoziemca w świetle Pamiętników z czasów Jana Sobieskiego, króla polskiego, Kazimierza Sarneckiego (1629–1696)
2013
Pamiętnik Kazimierza Sarneckiego należy do najczęściej wykorzystywanych źródeł do epoki Jana III Sobieskiego. Wspomnienia tego rezydenta na dworze Jana III, działającego z poruczenia kanclerza wielkiego litewskiego Karola Stanisława Radziwiłła, uzupełniają fakty znane z pamiętników Philippe Pierre de Noyersa, Philippe Duponta, Francois-Paulina d’Aleyraca i sekretarza ambasady francuskiej kawalera de Mongrillona. Wyróżniają się także dlatego, że mocodawcą Sarneckiego był siostrzeniec monarchy, syn Katarzyny z Sobieskich, primo voto Zasławskiej, a secundo voto Radziwiłłowej. Kazimierzowi Sarneckiemu zawdzięczamy szczegółowy obraz życia codziennego Jana III i jego rodziny w ostatnich latach ży…
Translationally invariant coupled cluster method in coordinate space for nuclei
2002
We study a formulation of the translationally invariant coupled cluster method in coordinate space for finite nuclei. The new formulation remedies convergence problems that plagued previous calculations in configuration space. The method is applied to light nuclei using semi-realistic central interactions.
Image Analysis of Proliferating Cells in Tumors of the Human Nervous System
1994
Obtaining growth fractions from immunohistological preparations by the commonly used cell count calculation method is time consuming. For the first time, we investigated and compared the detection of proliferating cells in immunohistologically labeled tissue from tumors of the nervous system using the monoclonal antibody Ki-67 by a new computerized image analysis system and by cell count calculation. The two methods showed a high correlation (correlation index, 0.98) in 37 gliomas (2 pilocytic astrocytomas, 10 Grade II astrocytomas, 5 Grade III astrocytomas, 20 Grade IV astrocytomas and glioblastoma multiforme) and a heterogenous group of 10 additional tumors of the nervous system, includin…
