Les importations d'amphores orientales tardives en Gaule méridionale (IVe-VIIe siècles)

International audienceL'étude d'une masse considérable de matériel, acquis ces dix dernières années, a révélé de nombreuses lacunes tant au sujet des typologies que des chronologies. Aussi, il paraît aujourd'hui indispensable de s'affranchir des différents outils typologiques proposés, et notamment ceux élaborés depuis 1976 par J.A. Riley, qui, s'ils permirent de mettre en évidence un matériel jusqu'alors méconnu, ne parviennent plus à traduire la complexité des variations chrono-typologiques. Dans cette communication, il n'est pas question de proposer une nouvelle typologie des amphores orientales tardives mais il s'agît plutôt de compléter et de préciser celle de Riley élaborée à Carthage, et dont les appellations " Late Roman Amphorae " (LRA 1 à 7) restent les plus usitées actuellement

Les importations d'amphores orientales en Gaule méridionale durant l'Antiquité tardive et le haut Moyen Age (IVe-VIIe s. apr. J.-C.). Typologie, chronologie et contenu.

International audienceL'étude d'une masse considérable de matériel inédit, acquis ces dernières années, a permis la mise à jour des connaissances sur les amphores orientales tardives, ces nouvelles données répondant parfois à différentes interrogations restées jusqu'alors sans réponses. Parmi les données récentes, il faut surtout insister sur les résultats significatifs obtenus à Marseille dans divers lieux de la ville. En dehors de Marseille, les résultats obtenus à partir de mobiliers provenant de divers points du sud de la France, comme par exemple ceux d'Arles, Fos-sur-Mer, Saint-Blaise, Port-Vendres, Toulon, Narbonne, Toulouse, Bordeaux, Avignon, ainsi que ceux de trois épaves permettent d'enrichir ponctuellement les données marseillaises

Amphores du Ve au VIIe s. à Marseille: nouvelles données sur la typologie et le contenu

Les fouilles archéologiques de sauvetage menées depuis plus de 25 ans à Marseille, ville dont l'importance à la fin de l'Antiquité n'est plus à démontrer, ont produit des masses considérables de mobiliers datant des Ve-VIIe s. En ce qui concerne les amphores, l'examen d'une vingtaine de contextes stratigraphiques permet dès maintenant d'apporter de nouvelles données chronologiques et typologiques, ponctuellement enrichies par des comparaisons avec des mobiliers découverts en d'autres points du littoral français

Note sur un lot d'amphores du Ve siècle de notre ère à Narbonne (Aude).

International audienceIl s'agit du compte rendu d'une étude céramologique menée à partir d'un lot de mobilier inédit de Narbonne dont l'intérêt réside dans la diversité des produits méditerranéens importés (Afrique du Nord, Méditerranée orientale, péninsule ibérique) au second quart du Ve s. siècle apr. J.-C

Dynamic configuration of the CMS Data Acquisition cluster

The CMS Data Acquisition cluster, which runs around 10000 applications, is configured dynamically at run time. XML configuration documents determine what applications are executed on each node and over what networks these applications communicate. Through this mechanism the DAQ System may be adapted to the required performance, partitioned in order to perform (test-) runs in parallel, or re-structured in case of hardware faults. This paper presents the CMS DAQ Configurator tool, which is used to generate comprehensive configurations of the CMS DAQ system based on a high-level description given by the user. Using a database of configuration templates and a database containing a detailed model of hardware modules, data and control links, nodes and the network topology, the tool automatically determines which applications are needed, on which nodes they should run, and over which networks the event traffic will flow. The tool computes application parameters and generates the XML configuration documents as well as the configuration of the run-control system. The performance of the tool and operational experience during CMS commissioning and the first LHC runs are discussed

The Run Control and Monitoring System of the CMS Experiment

The CMS experiment at the LHC at CERN will start taking data in 2008. To configure, control and monitor the experiment during data-taking the Run Control and Monitoring System (RCMS) was developed. This paper describes the architecture and the technology used to implement the RCMS, as well as the deployment and commissioning strategy of this important component of the online software for the CMS experiment

High Level Trigger Configuration and Handling of Trigger Tables in the CMS Filter Farm

The CMS experiment at the CERN Large Hadron Collider is currently being commissioned and is scheduled to collect the first pp collision data in 2008. CMS features a two-level trigger system. The Level-1 trigger, based on custom hardware, is designed to reduce the collision rate of 40 MHz to approximately 100 kHz. Data for events accepted by the Level-1 trigger are read out and assembled by an Event Builder. The High Level Trigger (HLT) employs a set of sophisticated software algorithms, to analyze the complete event information, and further reduce the accepted event rate for permanent storage and analysis. This paper describes the design and implementation of the HLT Configuration Management system. First experiences with commissioning of the HLT system are also reported

An analysis of the control hierarchy modeling of the CMS detector control system

The supervisory level of the Detector Control System (DCS) of the CMS experiment is implemented using Finite State Machines (FSM), which model the behaviours and control the operations of all the sub-detectors and support services. The FSM tree of the whole CMS experiment consists of more than 30.000 nodes. An analysis of a system of such size is a complex task but is a crucial step towards the improvement of the overall performance of the FSM system. This paper presents the analysis of the CMS FSM system using the micro Common Representation Language 2 (mcrl2) methodology. Individual mCRL2 models are obtained for the FSM systems of the CMS sub-detectors using the ASF+SDF automated translation tool. Different mCRL2 operations are applied to the mCRL2 models. A mCRL2 simulation tool is used to closer examine the system. Visualization of a system based on the exploration of its state space is enabled with a mCRL2 tool. Requirements such as command and state propagation are expressed using modal mu-calculus and checked using a model checking algorithm. For checking local requirements such as endless loop freedom, the Bounded Model Checking technique is applied. This paper discusses these analysis techniques and presents the results of their application on the CMS FSM system

ECMO for COVID-19 patients in Europe and Israel

Since March 15th, 2020, 177 centres from Europe and Israel have joined the study, routinely reporting on the ECMO support they provide to COVID-19 patients. The mean annual number of cases treated with ECMO in the participating centres before the pandemic (2019) was 55. The number of COVID-19 patients has increased rapidly each week reaching 1531 treated patients as of September 14th. The greatest number of cases has been reported from France (n = 385), UK (n = 193), Germany (n = 176), Spain (n = 166), and Italy (n = 136) .The mean age of treated patients was 52.6 years (range 16–80), 79% were male. The ECMO configuration used was VV in 91% of cases, VA in 5% and other in 4%. The mean PaO2 before ECMO implantation was 65 mmHg. The mean duration of ECMO support thus far has been 18 days and the mean ICU length of stay of these patients was 33 days. As of the 14th September, overall 841 patients have been weaned from ECMO support, 601 died during ECMO support, 71 died after withdrawal of ECMO, 79 are still receiving ECMO support and for 10 patients status n.a. . Our preliminary data suggest that patients placed on ECMO with severe refractory respiratory or cardiac failure secondary to COVID-19 have a reasonable (55%) chance of survival. Further extensive data analysis is expected to provide invaluable information on the demographics, severity of illness, indications and different ECMO management strategies in these patients
