Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a myocardial disease in which the myocardium of the right ventricular free wall is partially or almost entirely replaced by fatty or fibrofatty tissue [1–3]. The process begins at the epicardium and gradually extends through the myocardium towards the subendocardium. The anterior right ventricular outflow tract, ]the apex, and the...
The ITER project requires neutral beam injection; such additional heating power will be provided by two injectors accelerating negative ions. To study and optimise negative ion production, the SPIDER prototype is under construction in Padova, Italy, whose beam has an energy of 100 keV and a current of 50 A. The instrumented calorimeter STRIKE (Short-Time Retractable Instrumented Kalorimeter Experiment)...
The Vacuum vessel of the ITER Heating Neutral Beam injector is a key component of the neutral beam system. It supports the injector components and is also an extension of the ITER Vacuum Vessel. This paper presents the status of the design of the vessel. In the first part of this paper we present the main design requirements. Besides the pressure and thermal loads, the various interfaces with other...
In this work, we report the dielectric properties and microstructure of the Mn doped CaCu3Ti4O12 fibres, grown by the laser floating zone technique, using different pulling rates (Rp). The samples were studied by X-ray diffraction, scanning electronic microscopy, energy dispersive X-ray spectroscopy and AC impedance spectroscopy. The microstructure of CaCu3Ti4−xMnxO12 fibres has been analyzed and...
Experimental rodent models of induced ischemic injury have been extensively used in biomedical research to study molecular, cellular and histological alterations following myocar-dial infarction. These models are increasingly employed to assess the potential of newly developed therapies for functional restoration of the damaged heart. Such studies are based on myocardial infarction induction followed...
While a large body of experimental works provided results about stimulus evoked activities in primary sensory cortices, the functional role and the dynamics of spontaneous activity (SA) have been less widely addressed. From the dynamical perspective, a major open problem is represented by the evolution of SA, most modeling works tacitly assuming SA activity to be essentially random. The alternative...
Summary form only given. Particle accelerator performance, in particular the average accelerating field and the cavity quality factor, depends on the physical and chemical characteristics of the superconducting radio-frequency (SRF) cavity surface. Plasma based surface modification provides an excellent opportunity to eliminate non-superconductive pollutants in the penetration depth region and to...
Summary form only given. Superconducting radio-frequency (SRF) particle accelerators rely on bulk Niobium cavities to accelerate the particle beam. Given that the London penetration depth for the superconductor is less than 100 nm, most of the costly bulk material is wasted. One alternative is to coat cheaper Copper structures with a thin film of Niobium. The Niobium coated Copper cavities benefit...
Superconducting radio-frequency (SRF) particle accelerators rely on bulk Niobium cavities to accelerate the particle beam. Since the skin depth for the superconductor is ≪100nm, the bulk of the costly Nb material is unnecessary. An alternative is to coat less expensive copper structures with just a thin film of Niobium. The Niobium coated Copper cavities benefit from the superior thermal properties...
