An echo-scintigraphic probe for medical applications and the method of merging images. It is constituted by the union of an ultrasound probe suitably integrated, both in geometric terms, and in terms of image processing, with a scintigraphic probe or gamma camera (3). With a single application of said probe, one is able to provide a double image of the object under examination. The ultrasound probe is housed in the head, above the plane of the collimator and kept projecting to favor the direct contact with the body part of the patient to be examined. The collimator is able to obtain images of the biodistribution of a radiolabelled drug by radiation with frontal incidence, maintaining the characteristics of the ultrasound probe. The probe is applicable to both clinical diagnosis and intraoperative diagnosis of cancer with the use of radio tracers. A guided diagnostic method is disclosed that realizes a functional integration of a pair of ultrasound and scintigraphic images concurrently obtained by the echo-scintigraphic probe.

The present invention relates to a rectifier for a sensor of electromagnetic signal, said electromagnetic signal having a frequency between 300Ghz and 10THz. Said rectifier comprising: - a semiconductor substrate (1 ) doped p comprising a electrons/holes gathering well (2) for gathering electrons/holes; said electrons/holes gathering well (2) being arranged inside said semiconductor substrate (1 ) and comprising at least a first zone doped n/p (21 ); said first zone doped n/p (21 ) having an end surface (21 A); - a metal end surface (41 ) of an antenna (4), said antenna being capable of receiving and concentrating said electromagnetic signal; - a layer doped p (3) having a first surface (31) and a second surface (32), opposite to said first surface (31 ). In particular, a first portion of said first surface (31) of said layer doped p (3) is in contact with said end surface (21 A) of said first zone doped n/p (21 ) of the electrons/holes gathering well (2), so as to form a first metallurgical junction (G1 ), and a first portion of said second surface (32) of said layer doped p (3) is in contact with said metal end surface (41 ), so as to form a second metallurgical junction (G2). The concentration of the doping of said layer doped p (3) and the concentration of the doping of said first zone doped n/p (21) of said electrons/holes gathering well (2) are such that said first metallurgical junction (G1) has a first potential barrier (VZ1) inside and the work function of the metal of said metal end surface (41 ) is selected such that it is equal to that of a semiconductor doped n/p and such that said second metallurgical junction (G2) has a second potential barrier (Vzz) inside. Said first metallurgical junction (G1 ) and said second metallurgical junction (G2) form a double metallurgical junction n-p-n/p-n-p with a double potential barrier composed of said first potential barrier (Vz1) and said second potential barrier (Vz2), where said double metallurgical junction n-p-n/p-n-p comprises a first depletion zone (Z1 ), and a second depletion zone (Z2), in contact with said first depletion zone (Z1 ) along a line of contact (A), disposed within said layer doped p (3), said first depletion zone (Z1 ) having a thickness greater than the thickness of the second depletion zone (Z2); said first potential barrier (Vzi) being associated with said first depletion zone (Z 1 ), and said second potential barrier (Vz2) being associated with said second depletion zone (Z2). Said layer doped p (3) is dimensioned in such a way that said double potential barrier has a value such as to allow said layer doped p (3) being completely deprived of holes/electrons, so that, when a variable electric field is induced by said electromagnetic signal received by said antenna (4), said double metallurgical junction n-p-n/p-n-p is subjected to said variable electric field, and a first potential difference (AV^) and a second potential difference (AVZ2) are generated, through the first depletion zone (Z1 ) and through the second depletion zone (Z2) respectively, where each potential difference (Vzi, Vz2) is proportional to the thickness of the respective depletion zone (Z1, Z2) and is added algebraically to the respective potential barrier (Vz1, Vz2). The present invention relates also to a charge gathering system comprising said rectifier.

HarmonicSS vision is to create an International Network and Alliance of partners and cohorts, entrusted with the mission of addressing the unmet needs in primary Sjogren Syndrome; working together to create and maintain a platform with open standards and tools, designed to enable secure storage, governance, analytics, access control and controlled sharing of information at multiple levels along with methods to make results of analyses and outcomes comparable across centers and sustainable through Rheumatology associations. The overall idea of the HarmonicSS project is to bring together the largest well characterized regional, national and international longitudinal cohorts of patients with Primary Sjgrens Syndrome (pSS) including those participating in clinical trials, and after taking into consideration the ethical, legal, privacy and IPR issues for sharing data from different countries, to semantically interlink and harmonize them into an integrative pSS cohort structure on the cloud. Upon this harmonized cohort, services for big data mining, governance and visual analytics will be integrated, to address the identified clinical and health policy pSS unmet needs. In addition, tools for specific diagnostic procedures (e.g. ultrasonography image segmentation), patient selection for clinical trials and training will be also provided. The users of the HarmonicSS platform are researchers (basic/translational), clinicians, health policy makers and pharma companies. pSS is relevant not only due to its clinical impact but also as one of the few model diseases to link autoimmunity, cancer development (lymphoproliferation) and the pathogenetic role of infection. Thus, the study of pSS can facilitate research in many areas of medicine; for this reason, the possibility for sustainability and expandability of the platform is enhanced. Moreover, pSS has a significant impact on the healthcare systems, similar to that of rheumatoid arthritis.

Hard spheres are ubiquitous in condensed matter: they have been used as models for liquids, crystals, colloidal systems, granular systems, and powders. Packings of hard spheres are of even wider interest as they are related to important problems in information theory, such as digitalization of signals, error correcting codes, and optimization problems. In three dimensions the densest packing of identical hard spheres has been proven to be the fcc lattice, and it is conjectured that the closest packing is ordered (a regular lattice, e.g., a crystal) in low enough dimension. Still, amorphous packings have attracted much interest because for polydisperse colloids and granular materials the crystalline state is not obtained in experiments for kinetic reasons. A theory of amorphous packings, and more generally glassy states, of hard spheres is reviewed here, that is based on the replica method: this theory gives predictions on the structure and thermodynamics of these states. In dimensions between two and six these predictions can be successfully compared with numerical simulations. The limit of large dimension is also discussed where an exact solution is possible. Some of the results presented here were published, but others are original: in particular, an improved discussion of the large dimension limit and new results on the correlation function and the contact force distribution in three dimensions. The main assumptions that are beyond the theory presented are clarified and, in particular, the relation between static computation and the dynamical procedures used to construct amorphous packings. There remain many weak points in the theory that should be better investigated. © 2010 The American Physical Society.

NEXTOWER shall introduce a set of innovative materials to boost the performance of atmospheric air-based concentrated solar power (CSP) systems to make them commercially viable. In particular, tower systems are appealing for the great environmental compatibility and offer tremendous potential for efficient (electrical and thermal) power generation. Yet, their industrial exploitation has been so far hindered by limitations in the materials used both for the central receiver - the core component - and for thermal storage. Such limitations dictate maximum working temperature and in-service overall durability (mainly driven by failure from thermal cycling and thermal shocks). Improving the efficiency of a tower system entails necessarily improving the central receiver upstream and possibly re-engineering the whole systems downstream to work longer and at much higher temperature, especially in the thermal storage compartment. NEXTOWER will address this need by taking a comprehensive conceptual and manufacturing approach that will optimize bulk and joining materials for durability at the component level to achieve 25 years of maintenance-free continued service of the receiver and maximum thermodynamic efficiency at the system level. This is made possible through a unique combination of excellence in materials design and manufacturing, CSP full-scale testing facilities brought together in the Consortium, supporting the making of a new full scale demo SOLEAD (in Turkey) within the project. The successful achievement of a new generation of materials allowing for virtually maintenance free operations and increased working temperature shall result in the next-generation of air-coolant CSP highly competitive over other CSP alternatives and sustainable power supply options.
