We present the results of the single-component Sérsic profile fitting for the magnitude-limited sample of IE < 23 galaxies within the 63.1 deg2 area of the Euclid Quick Data Release (Q1). The associated morphological catalogue includes two sets of structural parameters fitted using SourceXtractor++: one for VIS IE images and one for a combination of three NISP images in YE, JE, and HE bands. We compared the resulting Sérsic parameters to other morphological measurements provided in the Q1 data release and t

The well-known bimodality between star-forming discs and quiescent spheroids requires the existence of two main processes: galaxy quenching, causing the strong reduction of star formation, and morphological transformation, causing the transition from disc-dominated structures to bulge-dominated ones. In this paper, we aim to understand the link between these two processes and their relation with the stellar mass of galaxies and their local environment. Taking advantage of the first data released by the Eucl

Road traffic crashes are the leading cause of injuries, disabilities, and fatalities for children and young adults. Extremity joint injuries have been identified as one of the contributing factors to chronic disabilities among children in road crashes. However, our knowledge on the biomechanics of the pediatric upper and lower extremity joints remains limited. Understanding the biomechanics of the upper and lower extremity joints is essential to provide important information for developing enhanced protecti

The present invention concerns a variable stiffness catheter (1) for surgical applications, a system (2) and a method for manufacturing said catheter, wherein said catheter (1) comprises at least one soft biocompatible hollow sleeve (S) and further including: - a tip sealing cap (10) at a distal end, - a working channel (15) enclosed within said sleeve (S) and extending from a proximal end to said distal end, for applying a treatment outside the catheter (1), through said tip sealing cap (10), - a plurality

Surgical sealants are widely used in cardiothoracic and vascular surgery essentially for hemostasis and sealing. Their adhesive properties have mainly been studied by clinical experiments. The objective of this study is to measure adhesion of the three main types of surgical sealant used in cardiothoracic and vascular surgery under normalized realistic conditions. The bulge-and-blister test was used to quantify adhesive performances of three types of surgical adhesives: cyanoacrylates, polyethylene glycol (

Partial-thickness tears of the supraspinatus tendon frequently occur at its insertion on the greater tubercule of the humerus, causing pain and reduced strength and range of motion. The goal of this work was to quantify the loss of loading capacity due to tendon tears at the insertion area. A finite element model of the supraspinatus tendon was developed using in vivo magnetic resonance images data. The tendon was represented by an anisotropic hyperelastic constitutive law identified with experimental measu

In this study, we attempt for the first time to couple sonication and photo-Fenton for bacterial inactivation of secondary treated effluent. Synthetic wastewater was subjected to sequential high-frequency/low power sonication, followed by mild photo-Fenton treatment, under a solar simulator. It was followed by the assessment of the contribution of each component of the process (Fenton, US, hv) towards the removal rate and the long-term survival; sunlight greatly improved the treatment efficiency, with the c

Although the procedure of total knee replacement (TKR) has been improved for the last decades, patients may still face postoperative complications. Specially, causes of complications related to patellar resurfacing, such as osteonecrosis, patellar bone fracture, anterior knee pain and implant failure, are still unclear. Predicting strain state of the patellar bone after TKR by means of numerical modeling may help in understanding and possibly preventing such complications. First TKR model has been already d

This is a comparative study of photolytic degradation under exposure to UV254 nm and solar-simulator irradiation of a mixture of eight equally concentrated relevant micropollutants (atenolol, benzotriazole, clarithromycin, gabapentin, methylbenzotriazole, metformin, metoprolol and primidone; 2 µM of each compound) in the presence of H2O2 and Fe(II) in ultrapure water, Lake Geneva water, and effluent from a wastewater treatment plant (WWTP). The results indicate that the oxidation rate increased in the prese

Mobile-bearing total knee arthroplasty has potential advantages over fixed- bearing prostheses that may lead to an improvement of the range of motion and inferior long-term polyethylene wear. However, the potential disadvantages include the dislocation of the PE tibial insert that is usually the result of quadriceps deficiency, ligament laxity and traumatic events. Therefore, 2 goals are pursued in this project. In a first step, an analysis of the existing literature will let to find out the causes of beari

The aim of this study was to test the association of fetal bone cells with ceramic reinforced PLA scaffolds for tissue engineering. As animal models, the craniotomy and the femoral condyle approaches in rats were chosen to follow cortical and trabecular bone repair processes. Key findings were the observation of complete bone bridging 12 months after implantation in skulls of PLA porous structures seeded with human fetal bone cells, and a strong induction of trabecular bone ingrowth in femoral condyles 2 mo

Gold nanoparticles of 2–5 nm supported on woven fabrics of activated carbon fibers (ACF) were effective during CO oxidation at room temperature. To obtain a high metal dispersion, Au was deposited on ACF from aqueous solution of ethylenediamine complex [Au(en)2]Cl3 via ion exchange with protons of surface functional groups. The temperature-programmed decomposition method showed the presence of two main types of functional groups on the ACF surface: the first type was associated with carboxylic groups easily
