The Cherenkov Telescope Array CTA will be the first open facility for gamma-ray astronomy in the very-high-energy domain, with a performance which is dramatically improved over existing instruments in terms of sensitivity, energy coverage, survey capability and flexibility. CTA will probe non-thermal phenomena in the Universe known to have comparable energy content to other forms of energy such as thermal radiation both in our own Galaxy and at cosmological distances, addressing questions in astrophysics, astroparticle physics, particle physics, plasma physics, cosmology, and fundamental physics. The CTA preparatory phase CTA-PP will address a number of crucial prerequisites for the approval, construction and operation of CTA: > the set-up of a Project Office offering means for electronic communication as well as data storage and handling for documents of the whole consortium > the legal framework, governance schemes, and financial regulations for the following phases of CTA (pre-construction, construction and operation) > assuring funding for the pre-construction phase after termination of CTA-PP > the preparation of funding agreements between potential funding agencies > the preparation of negotiations with potential host countries for the CTA instrument > the detailed technical design and costing of the CTA observatory > the selection of sites for deployment negotiations, and detailing and cost-estimation of the required site infrastructure > the schemes for procurement and industry involvement in the technical design and construction of CTA > the required linking with relevant science communities regarding the detailed definition of the science program, the corresponding final optimisation of the observatory layout, and the definition of user services and data access. For CTA-PP, support is sought primarily for work on the legal, governance and financial issues, for the installation of a project office coordinating and supporting management of CTA-PP as well as the design of CTA and the planning of the implementation, and for studies regarding the optimisation and production of CTA components by industry. The ultimate delivery of CTA-PP will be a detailed implementation plan for the CTA infrastructure.

The project objective is the definition and development of a framework enabling the successful integration and implementation at European level and beyond, of the Code of Conduct (CoC) for responsible N&N research defined by the EC. This will be done by: identifying and consulting stakeholders (scientific, institutional, industrial and Civil society organisations) to explore knowledge, attitudes, reactions and proposals in relation to the CoC assessing the most relevant codes of conducts, voluntary measures and practices for a responsible technology development, regarding in first place N&N R&D, already defined or under study ; proposing criteria and indicators of good practices to implement the CoC; basing on identified criteria and indicators, defining and testing a practical tool for the assessment of performances for the application of the CoC (CodeMeter) selecting a set of incentives and disincentives to stimulate the adoption of the CoC; identifying future regulatory, policy and research needs in order to integrate foresight oriented aspects in further developments of the CoC. designing of a CoC MasterPlan enabling the implementation and integration of the CoC, including future changes, best practices, incentives/disincentives and performance criteria for the adoption of the CoC. The project outcomes will support the EC, EU policy makers and stakeholders in the implementation of the European CoC and it will also help the EC to prepare the second CoC review (beginning 2012). The engagement of stakeholders in the debate will help to increase awareness on the CoC and in shaping its content to the stakeholders needs and expectations, making it a more accepted, concrete and practical instrument for decision-making in N&N R&D.

A key thrust of FP7 is to promote international collaborative research with third countries. The EULASUR project will address the Call for Co-ordination Action in Materials by creating a cooperation platform for forming strategic research partnerships between scientists, policy makers, technology transfer and industrial experts in the EC and 3 Latin-American countries belonging to MERCOSUR: Brazil, Uruguay and Argentina (BRAU). Research topics will be identified within the fields of i) advanced functional ceramics and ii) hybrid materials and nanomaterials where significant opportunities exist for mutually beneficial actions between the two regions. The goals are designed to gain first hand knowledge of the state of the art research in these fields through summer schools, exchanges and partnership actions. The project will also address the social, political and cultural factors impacting technology transfer and collaboration between the EU and BRAU countries. The core activities of EULASUR are based on some research Groups of Excellence that already cooperate bilaterally and will integrate them with additional groups to generate a stable, integrated scientific platform of international excellence interested to collaborate in the development of materials research in specific topics of interest to both regions. The EULASUR partnership is composed of 15 research centres, 8 from Europe and 7 from BRAU countries selected on the basis of: excellence in research, complementary skills and access to national and international R&D policy makers. Government representatives will participate in the EULASUR Advisory Board. Industrial companies and technological centres are expected to take part in the project activities. EULASUR has 5 WPs. 3 designed to build contacts and identify opportunities, 1 to disseminate results to key stakeholders and policy makers and 1 management and progress measures. Each WP has two WP Leaders: one from BRAU and the other from the EU.

Reviews of Modern Physics | Year: 2015
In the past decade modern societies have developed enormous communication and social networks. Their classification and information retrieval processing has become a formidable task for the society. Because of the rapid growth of the World Wide Web, and social and communication networks, new mathematical methods have been invented to characterize the properties of these networks in a more detailed and precise way. Various search engines extensively use such methods. It is highly important to develop new tools to classify and rank a massive amount of network information in a way that is adapted to internal network structures and characteristics. This review describes the Google matrix analysis of directed complex networks demonstrating its efficiency using various examples including the World Wide Web, Wikipedia, software architectures, world trade, social and citation networks, brain neural networks, DNA sequences, and Ulam networks. The analytical and numerical matrix methods used in this analysis originate from the fields of Markov chains, quantum chaos, and random matrix theory. © 2015 American Physical Society.

The contribution of different components of sunlight to the lethal action exerted by this radiation on bacteria was studied using Pseudomonas aeruginosa ATCC27853 as a model organism. When solar UVB was excluded from the incident radiation by filtering it through a naphthalene solution (cut off 327 nm), significant modifications were observed in the cell-death kinetics. These modifications were comparable to those expected for a reduction of 27-32% in the dose rate, according to the model used in the analysis of the survival curves, and were also observed when the effects of sunlight filtered through polyethylene terephthalate (cut off 331 nm) or polystyrene (cut off 298 nm) were compared. Viability of P. aeruginosa remained almost unchanged when the incident radiation was filtered through a sodium nitrite solution (cut off 406 nm) in order to exclude the UVA and UVB components of sunlight. Nevertheless, a delay in colony formation was detected in bacteria treated in this way, suggesting that a non-lethal effect was exerted by visible light. The results are not consistent with a generally accepted notion which attributes the lethal action of sunlight to the radiation with wavelengths above 320 nm. The characterization of UVB contribution to the lethal effect of sunlight on bacteria is relevant for understanding of the mechanism of cell death, and for improvement of dosimetry techniques and irradiation procedures. © 2012 Elsevier B.V.

TiO2 membrane nanotubes prepared by anodization method was used for detection of d-butylamine (DBA) operating at low temperature. The TiO2 membrane nanotubes have an average diameter of 100 nm and a length of 12 μm. The flexible gas sensor was achieved using a flexible substrate onto which array interdigitated gold electrodes were obtained using conventional microfabrication procedure.The sensing characteristics were investigated by measuring the electrical resistance of the sensor in a test chamber as a function of gas concentration. This was used to detect DBA within a concentration range of 8-20 ppm.The results indicate that TiO2 membrane nanotubes has good potential in practical applications, due to its remarkable performance and facile synthesizing methods. © 2016 Elsevier Ltd.

The universal scaling behavior is studied for nonequilibrium transport through a quantum dot. To describe the dot we use the standard Anderson impurity model and use the nonequilibrium noncrossing approximation in the limit of infinite Coulomb repulsion. After solving de Hamiltonian, we calculate the conductance through the system as a function of temperature T and bias voltage V in the Kondo and in the mixed valent regime. We obtain a good scaling function in both regimes. In particular, in the mixed valent regime, we find excellent agreement with recent experiments and previous theoretical works. © 2010 The American Physical Society.

A fluidic device is disclosed for making electrophoresis of molecules. The device has channels of closed geometry and variable powers over time. Migration of molecules is contained within channel of closed geometry, whereby they can circulate again and again, thus separating the molecules at a wide migration distance. The device has an injection system which is a secondary channel which intersects the main channel. An arrangement of electrodes along this main channel connected to a variable voltage source with multiple outlets which regulates the value of the electric power in each electrode, and the frequency at which the same varies from one electrode to another. Thus it is achieved to generate a periodic arrangement of powers along the channel which set the flow of the sample optimizing the separation process. Electrodes can be added for the detection of molecules by measuring the changes in electric resistivity, current or voltage.

A method of quantization of magnetic nanoparticle absorption in animal tissues includes determination of the number of magnetic nanoparticles absorbed in animal tissues by magnetization measurements. The method is based on the measurement of magnetization versus magnetic field applied of the tissue sample absorbed with the nanoparticles obtaining their saturation magnetization. This magnitude is compared to the saturation magnetization of the same nanoparticles found in the tissue for the determination of the absolute number of magnetic nanoparticles in the animal tissue studied. The method includes preparing the samples for the sample holder, measuring the magnetization vs. applied magnetic field of a known number of magnetic nanoparticles, determining the saturation magnetization of the sample to be studied by measuring the magnetization and calculating the nanoparticle mass in the tissues from the data measured (saturation magnetization of the sample and of calibration of nanoparticles).
