Cas Clinique: Anévrisme de l’Aorte Abdominale Compliqué de Thrombose à Propos d’Un Cas

L’anévrisme de l’aorte abdominale est une dilatation permanente de l’aorte abdominale dans sa portion sous-rénale. Les conséquences, en cas de rupture anévrismale, peuvent être fatales. La plupart des anévrismes de l’aorte abdominale ne présentent pas de symptômes jusqu’au moment de la rupture. Le symptôme le plus courant est la douleur abdominale ou dorsale Parfois, une masse pulsatile (qui présente des pulsations) peut être palpée au niveau de l’abdomen. Le diagnostic paraclinique est basé sur l’échographie abdominale et l’angiotomodensitométrie. Le dépistage est recommandé chez tous les hommes fumeurs de plus de 65 ans ayant un parent de premier degré connu pour un anévrisme de l’aorte abdominale. Les anévrismes asymptomatiques présentant un diamètre de plus de 50mm chez la femme, 55mm chez l’homme ou une croissance du diamètre de plus de 1cm par année doivent être opérés. Le traitement est chirurgical ou endovasculaire. Le traitement médicale consiste à lutter contre les facteurs de risque athéromateux.   The abdominal aortic aneurysm is a permanent dilation of the abdominal aorta in its sub-renal portion. The consequences, in the event of an aneurysmal rupture, can be fatal. Most abdominal aortic aneurysms do not show symptoms until the moment of rupture. The most common symptom is abdominal or back pain Sometimes a throbbing mass (which is pulsating) can be felt in the abdomen. Paraclinical diagnosis is based on abdominal ultrasound and CT angiography. Screening is recommended for all male smokers over 65 years of age with a first-degree relative known to have an abdominal aortic aneurysm. Asymptomatic aneurysms with a diameter of more than 50mm in women, 55mm in men or with a diameter growth of more than 1cm per year should be operated on. Treatment is surgical or endovascular. The medical treatment consists in combating the atherosclerotic risk factors

Equations de la MHD en milieu hétérogène

Dynamo effect is one of the most commonly accepted explanation for the existence of a magnetic field on Earth. Aiming to the numerical simulation of the VKS2 experiment (one of the successful experiments highlighting dynamo effect), a numerical code (SFEMaNS) has been developed. It combines the use of Fourier decomposition in an azimuthal direction, and a Lagrange Finite Element Solver in meridian planes. This choice of FE is a challenging task and requires a non-standard approach. Results have been successfully confronted to experimental results and to other numerical simulations

Overcoming I/O bottleneck in superconducting quantum computing: multiplexed qubit control with ultra-low-power, base-temperature cryo-CMOS multiplexer

Large-scale superconducting quantum computing systems entail high-fidelity control and readout of large numbers of qubits at millikelvin temperatures, resulting in a massive input-output bottleneck. Cryo-electronics, based on complementary metal-oxide-semiconductor (CMOS) technology, may offer a scalable and versatile solution to overcome this bottleneck. However, detrimental effects due to cross-coupling between the electronic and thermal noise generated during cryo-electronics operation and the qubits need to be avoided. Here we present an ultra-low power radio-frequency (RF) multiplexing cryo-electronics solution operating below 15 mK that allows for control and interfacing of superconducting qubits with minimal cross-coupling. We benchmark its performance by interfacing it with a superconducting qubit and observe that the qubit's relaxation times ($T_1$) are unaffected, while the coherence times ($T_2$) are only minimally affected in both static and dynamic operation. Using the multiplexer, single qubit gate fidelities above 99.9%, i.e., well above the threshold for surface-code based quantum error-correction, can be achieved with appropriate thermal filtering. In addition, we demonstrate the capability of time-division-multiplexed qubit control by dynamically windowing calibrated qubit control pulses. Our results show that cryo-CMOS multiplexers could be used to significantly reduce the wiring resources for large-scale qubit device characterization, large-scale quantum processor control and quantum error correction protocols.Comment: 16+6 pages, 4+1+5 figures, 1 tabl
