Cernay-lès-Reims (Marne). Cernay-lès-Reims « le Bas de la Noue Saint Rémy » zone 9 [notice archéologique]
2019
Localisée en limite SE de l’agglomération rémoise, sur la commune de Cernay-les-Reims, l’emprise de l’opération porte sur une surface de 11 300 m2. Cette neuvième concentration de vestiges, fouillée sur un parc d’activité, correspond à un établissement rural de l’Antiquité tardive, prolongé à l’époque médiévale par une zone d’activité artisanale. Ces deux occupations se développent le long d’un axe de circulation qui perdure vraisemblablement de l’Antiquité à la première guerre mondiale.
Networking Brains: Modeling Spatial Relationships of the Cerebral Cortex
2017
Brain mapping has always been a priority in neurobiology and evolutionary neuroanatomy. In the last century, methodological issues and technical advances have generated a vivid debate on the parcellation and functions of the cortical territories. Brain structure is generally analyzed by considering the network of connections associated with neural pathways. Nonetheless, there is still a major debate on the recognition of the spatial and geometrical components of the cerebral cortex. The maps produced by Korbinian Brodmann in the early twentieth century on the basis of histological patterns represented a pioneering and decisive step in this sense, being a reference until the present day. Net…
Le cimetière du second âge du Fer de Lailly au-delà de l'eau (Yonne) : découvertes anciennes et fouilles récentes
2023
Die Nekropole von Lailly Au-delà de l’Eau (Departement Yonne) war 1927 entdeckt worden und wurde1934, 1936 und 1937 und zum letzten Mal 2012 teilweise ausgegraben. Die Untersuchung der in den Depots der Museen von Senswiederentdeckten Grabbeigaben und die systematische Aufarbeitung der Grabungsarchive der Société archéologique de Sens habenes ermöglicht, einen Teil der geschlossenen Fundkontexte zu rekonstruieren und eine Belegungschronologie dieser kleinen Nekropolevorzuschlagen, deren großes wissenschaftliches Potenzial noch in situ erforscht werden muss. Die Studie der Grabsitten hat es zudemerlaubt, die Funde in den regionalen und überregionalen soziokulturellen Kontext zu einzuordnen
Disrupted Spatial Organization of Cued Exogenous Attention Persists Into Adulthood in Developmental Dyslexia
2021
Purpose: Abnormal exogenous attention orienting and diffused spatial distribution of attention have been associated with reading impairment in children with developmental dyslexia. However, studies in adults have failed to replicate such relationships. The goal of the present study was to address this issue by assessing exogenous visual attention and its peripheral spatial distribution in adults with developmental dyslexia.Methods: We measured response times, accuracy and eye movements of 18 dyslexics and 19 typical readers in a cued discrimination paradigm, in which stimuli were presented at different peripheral eccentricities.Results: Results showed that adults with developmental dyslexia…
A Multi-scalar Approach to Long-Term Dynamics, Spatial Relations and Economic Networks of Roman Secondary Settlements in Italy and the Ombrone Valley…
2019
AbstractIn Roman landscapes, the particular sites defined as secondary settlements (also known as vici/villages, minor centres, agglomérations secondaires and/or stationes/mansiones) have played an ‘intermediary’ role between the cities and other rural structures (villae/farms), linked to medium- and long-distance economic and commercial trajectories. The aim of this paper is to apply a multi-scalar approach to model their long-term spatial relationships and connectivity with the Mediterranean exchange network. On the macro-scale, we have analysed a sample of 219 reviewed sites to understand the diachronic trends and spatial dynamics of attraction/proximity to significant elements of the la…

Division of labor is a defining characteristic of social insects and fundamental to their ecological success. Many of the numerous tasks essential for the survival of the colony must be performed at a specific location. Consequently, spatial organization is an integral aspect of division of labor. The mechanisms organizing the spatial distribution of workers, separating inside and outside workers without central control, is an essential, but so far neglected aspect of division of labor. In this study, we investigate the behavioral mechanisms governing the spatial distribution of individual workers and its physiological underpinning in the ant Myrmica rubra. By investigating worker personali…
Foraging site fidelity shapes the spatial organisation of a population of female western barbastelle bats
2009
Abstract Information about the spatial distribution of individual foraging habitats, which determines the space required by a population to be viable, is vitally important for the conservation of bats. Detailed knowledge of this kind is crucial for the design of nature reserves and management plans. Recent field studies that examined habitat use and home range distribution of bats largely ignored factors like traditional range use vs. intra- and interspecific competition, which may be responsible for the spatial organisation of a population home range. We investigated the home range sizes and distribution of a maternity colony of the western barbastelle bat via radio telemetry in four conse…
From fractal urban pattern analysis to fractal urban planning concepts
2014
International audience; Fractal geometry can be used to develop a multiscale approach toinvestigate the spatial organization of urban fabrics. First, the concepts behindfractal reference models are introduced so as to provide a better understandingof the results obtained from empirical analyses of urban patterns. Then, differentmethods for conducting fractal analyses are presented and the results obtained forurban patterns are discussed. It turns out that, despite their irregular appearance,urban patterns are often organized by an inherent fractal order principle, at leastacross a certain range of scales. More detailed analysis of the findings reveals linksbetween these fractal properties a…
