Manufacturing of four-quadrant phase mask for nulling interferometry in the thermal infrared

The Four Quadrant Phase Mask is a key component for the design of advanced coronagraphs that may be used to search exo-planets. The validity of this concept has been demonstrated in the visible and need now to be demonstrated in the mid infrared. For this purpose, two components are manufactured for wavelengths 4.75 and 16.25 μm. This manufacturing requires the deposition of ZnSe layers using Ion Assisted Deposition, followed by a lift off process

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

LES MYOCARDIOPATHIES

Myocardiopathies may be either primary or secondary. They may be hypertrophic, congestive, obliterative or restrictive. Physiopathology and clinical aspects of the main forms are briefly reviewed. Presently available therapeutic procedures are described.SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

Étude hémodynamique des anévrysmes artérioveineux périphériques

In patients with clinical or experimental arteriovenous aneurysms, systemic vascular resistances are decreased, cardiac output is increased, sometimes very much so, and heart rate is accelerated. Temporary or definitive occlusion of the aneurysm decreases blood pressure and stroke output, and slows heart rate down (Branham's phenomenon). Increased cardiac work, related to increased cardiac output, brings out cardiac failure. At that time, left and right cardiac and pulmonary arterial pressures are increased; cardiac output decreases but remains above normal figures; it is, as a matter of fact, insufficient to meet the body requirements in oxygen. On effort, these patients behave as other cases of cardiac failure: pulmonary arterial pressures become definitely higher while cardiac output does not increase as much as it should. In Paget's disease, hemodynamic changes are more or less similar to those observed in patients with peripheral arteriovenous aneurysms. © 1965 Dr. Dietrich Steinkopff Verlag.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
