Un nouveau regard sur les épées à poignée métallique de l’âge du Bronze à la lumière des rayons X

2023

Les épées de l’âge du Bronze, a fortiori celles à poignée métallique, figurent parmi les objets les mieux documentés de la période, avec un grand nombre d’études réalisées à l’échelle européenne depuis la fin du XIXe siècle. Malgré tout, l’emploi de techniques d’imagerie utilisant les rayons X, telles que la radiographie et la tomographie, permettent de porter un regard nouveau sur ces armes grâce à l’examen de leurs entrailles qui révèlent certaines techniques mises en place par les artisans pour leur production. Ces épées sont en effet des objets complexes formés de plusieurs pièces agencées à l’aide de techniques variées, pour lesquelles les artisans de l’âge du Bronze se sont montrés tr…

Multi-channel search for squarks and gluinos in root s=7 TeV pp collisions with the ATLAS detector at the LHC

2013

A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb[superscript −1] of √s = 7 TeV pp collisions produced by the Large Hadron Collider and recorded by the ATLAS detector is presented. The search uses a set of variables carrying information on the event kinematics transverse and parallel to the beam line that are sensitive to several topologies expected in supersymmetry. Mutually exclusive final states are defined, allowing a combination of all channels to increase the search sensitivity. No deviation from the Standard Model expectation is observed. Upper limits at 95 % confidence level…

DIGITAL MARKETING PERFORMANCE EVALUATION METHODS

2018

The share of digital marketing from total marketing spending is increasing fast year by year. Still the majority of companies admit that they are missing clear methods on how to evaluate (positive/negative) effects obtained using digital marketing. As this field of digital marketing is relatively new, there are no firm and widely recognized measurement methods resulting in marketing specialists being confused by an overwhelming amount and variety of different digital marketing metrics and large amounts of data. Therefore, the aim of this paper is to list the existing methods which could help marketers to evaluate their digital marketing campaign effectiveness and to discuss these methods’ e…

Theoretical study of a Bénard Marangoni problem

2011

[EN] In this paper we prove the existence of strong solutions for the stationary Benard-Marangoni problem in a finite domain flat on the top, bifurcating from the basic heat conductive state. The Benard-Marangoni problem is a physical phenomenon of thermal convection in which the effects of buoyancy and surface tension are taken into account. This problem is modelled with a system of partial differential equations of the type Navier-Stokes and heat equation. The boundary conditions include crossed boundary conditions involving tangential derivatives of the temperature and normal derivatives of the velocity field. To define tangential derivatives at the boundary, intended in the trace sense,…

CODEX Weak Lensing Mass Catalogue and implications on the mass-richness relation

2021

The COnstrain Dark Energy with X-ray clusters (CODEX) sample contains the largest flux limited sample of X-ray clusters at $0.35 = \alpha \mu + \beta$, with $\mu = \ln (M_{200c}/M_{\mathrm{piv}})$, and $M_{\mathrm{piv}} = 10^{14.81} M_{\odot}$. We find a slope $\alpha = 0.49^{+0.20}_{-0.15}$, normalization $ \exp(\beta) = 84.0^{+9.2}_{-14.8}$ and $\sigma_{\ln \lambda | \mu} = 0.17^{+0.13}_{-0.09}$ using CFHT richness estimates. In comparison to other weak lensing richness-mass relations, we find the normalization of the richness statistically agreeing with the normalization of other scaling relations from a broad redshift range ($0.0<z<0.65$) and with different cluster selection (X-ray, Sun…

Wearable electromyography recordings during daily life activities in children with cerebral palsy.

2020

To test whether wearable textile electromyography (EMG) recording systems may detect differences in muscle activity levels during daily activities between children with cerebral palsy (CP) and age-matched typically developing children.Wearable textile EMG recording systems were used to obtain leg muscle activity in 10 children with spastic CP (four females, six males; mean age 9y 6mo, standard deviation [SD] 2y 4mo, range: 6-13y; Gross Motor Function Classification System [GMFCS] level I and II) and 11 typically developing children (four females, seven males; mean age 9y 9mo, SD 1y 11mo, 7-12y) at rest and while performing seven daily activities.Children with CP showed significantly lower a…

Difficult laparoscopic cholecystectomy and preoperative predictive factors

2021

AbstractLaparoscopic cholecystectomy (LC) is the standard technique for treatment of gallbladder disease. In case of acute cholecystitis we can identify preoperative factors associated with an increased risk of conversion and intraoperative complications. The aim of our study was to detect preoperative laboratory and radiological findings predictive of difficult LC with potential advantages for both the surgeons and patients in terms of options for management. We designed a retrospective case–control study to compare preoperative predictive factors of difficult LC in patients treated in emergency setting between January 2015 and December 2019. We included in the difficult LC group the surge…
