Le pont des Grilles de la Basse-Seille (fin XIVe siècle), ancienne porte d’eau de l’enceinte urbaine de Metz
2017
The bridge des Grilles de la Basse-Seille is one of the last vestiges of the medieval fortification in Metz. It is one of rare examples of fortified bridge in France. Built in the end of the 14th century, it is backfilled in 1911 and only its upper section is visible. An archaeological and historic study was made in 2011 to understand the configuration and the functioning of the bridge in the Middle Ages.
High Bias Voltage CZT Detectors for High-flux Measurements
2017
In this work, we present the performance of new travelling heater method (THM) grown CZT detectors, recently developed at IMEM-CNR Parma, Italy. Thick planar detectors (3 mm thick) with gold electroless contacts on CZT crystals grown by Redlen Technologies (Victoria BC, Canada) were realized, with a planar cathode covering the detector surface (4.1 x 4.1 mm(2)) and a central anode (2 x 2 mm(2)) surrounded by a guard ring electrode. The detectors, characterized by low leakage currents at room temperature (4.7 nA/cm(2) at 1000 V/cm), allow good room temperature operation even at high bias voltages (> 7000 V/cm). At low rates, the detectors exhibit an energy resolution around 4 % FWIEM at 59.5…
Microscale X-ray mapping of CZT arrays: Spatial dependence of amplitude, shape and multiplicity of detector pulses
2018
In this work, we present the results of a microscale X-ray mapping of a 2 mm thick CZT pixel detector, with pixel pitches of 500 μm and 250 μm, using collimated synchrotron X-ray sources at the Diamond Light source (U. K.). The detector is dc coupled to a fast and low noise ASIC (PIXIE ASIC), characterized only by the preamplifier stage. A custom 16-channel digital readout electronics was used, able to perform online fast pulse shape and height analysis (PSHA), with low dead time and reasonable energy resolution at both low and high fluxes. The detector allows high bias voltage operation (> 5000 V/cm) and good energy resolution at room temperature (5.3 %, 2.3 % and 2.1 % FWHM at 22.1, 59…
Role of the N-*(1535) in the J/psi -> pp and J/psi -> p(+)Lambda reactions
2009
We study the J/psi -> p eta p and J/psi -> pK(+)Lambda reactions with a unitary chiral approach. We find that the unitary chiral approach, which generates the N-*(1535) dynamically, can describe the data reasonably well, particularly the ratio of the integrated cross sections. This study provides further support for the unitary chiral description of the N-*(1535). We also discuss some subtle differences between the coupling constants determined from the unitary chiral approach and those determined from phenomenological studies

Red Blood Cells Distribution Width as Biomarker of Worsening in Atherosclerosis
2018
Red blood cell Distribution Width (RDW) is a parameter of the circulating erythrocytes’ size that it has reported to be associated with Cardiovascular Diseases (CVDs) [1-7]. The related mechanism of this association is not fully understood. However, RDW is an indicator of inflammation related to early inflammatory biomarkers, such as C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) [8,9]. Accordingly, systemic chronic inflammation leads to dysfunctional bone marrow with unsuccessful production of red blood cells [10]. As a result, it determines the migration of reticulocytes into the peripheral circulation, followed by an increase in circulating levels of i…
RED BLOOD CELL DISTRIBUTION WIDTH PREDICTS MORBIDITY AND MORTALITY AFTER AORTIC VALVE REPLACEMENT
2014
Objective: Red blood cell distribution width (RDW), is a measurement of the size variation as well as an erythrocyte heterogeneity index (i.e., anysocytosis). used in combination with the mean corpuscular volume for anemia diagnosis. However, it is emerging as an useful predictor biomarker of mortality and morbidity of cardiovascular diseases. However, until now no literature data there are about the RDW role in predicting mortality after aortic valve replacement (AVR). Thus, in this pilot study biological significance of elevated RDW values in early outcome following AVR was evaluated Methods: We enrolled 75 patients (mean age 73.5 ±7.9 years) subjected to AVR and/ or not co temporally to …
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
2021
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
