    The post-synthesis procedure for cyclic amine (morpholine and 1-methylpiperazine) modified mesoporous MCM-48 and SBA-15 silicas was developed. The procedure for preparation of the modified mesoporous materials does not affect the structural characteristics of the initial mesoporous silicas strongly. The initial and modified materials were characterized by XRD, N2 physisorption, thermal analysis, and solid-state NMR. The CO2 adsorption of the obtained materials was tested under dynamic and equilibrium conditions. The NMR data revealed the formation of different CO2 adsorbed forms. The materials exhibited high CO2 absorption capacity lying above the benchmark value of 2 mmol/g and stretching out to the outstanding 4.4 mmol/g in the case of 1-methylpiperazin modified MCM-48. The materials are reusable, and their CO2 adsorption capacities are slightly lower in three adsorption/desorption cycles.

    Complex service robotics scenarios entail unpredictable task appearance both in space and time. This requires robots to continuously relocate and imposes a trade-off between motion costs and efficiency in task execution. In such scenarios, multi-robot systems and even swarms of robots can be exploited to service different areas in parallel. An efficient deployment needs to continuously determine the best allocation according to the actual service needs, while also taking relocation costs into account when such allocation must be modified. For large scale problems, centrally predicting optimal allocations and movement paths for each robot quickly becomes infeasible. Instead, decentralized solutions are needed that allow the robotic system to self-organize and adaptively respond to the task demands. In this paper, we propose a distributed and asynchronous approach to simultaneous task assignment and path planning for robot swarms, which combines a bio-inspired collective decision-making process for the allocation of robots to areas to be serviced, and a search-based path planning approach for the actual routing of robots towards tasks to be executed. Task allocation exploits a hierarchical representation of the workspace, supporting the robot deployment to the areas that mostly require service. We investigate four realistic environments of increasing complexity, where each task requires a robot to reach a location and work for a specific amount of time. The proposed approach improves over two different baseline algorithms in specific settings with statistical significance, while showing consistently good results overall. Moreover, the proposed solution is robust to limited communication and robot failures.

    In early 2020, the EOSC Community took another crucial step on the road to the development and implementation of the European Open Science Cloud, as seven key EOSC-related Horizon 2020 projects signed a Collaboration Agreement in support of the EOSC Governance. The Agreement involves all the projects supported within the INFRAEOSC-05-2018-2019 call. The Agreement provides a useful framework for all parties to collaborate on a wide range of topics, in order to enhance synergies in all mutual activities related to the EOSC. The projects also agreed on a Joint Activity Plan, which will guide them towards the first iteration of EOSC. Overlaps and complementarities among projects were identified, as well as specific areas for potential cooperation, ultimately aimed at the development of a common strategy to synchronise activities with the EOSC Working Groups. Between April and May 2020, EOSCsecretariat.eu collected the position papers on EOSC compiled by the INFRAEOSC 5b projects, the subgroup that specifically includes the four regional projects covering all corners of Europe, as well as the thematic project ExPaNDS. We would like to thank the five Horizon 2020 projects which have contributed to the making of this compilation of EOSC position papers: EOSC-Nordic (GA No. 857652), EOSC-Pillar (GA No. 857650), EOSC-synergy (GA No. 857647), ExPaNDS (GA No. 857641), and NI4OS-Europe (GA No. 857645).

    In the HIIG blog series on metaphors of the digital society, we uncover the vocabularies that are thrown around almost haphazardly these days. These terms are often deployed in the scholarly and societal discourse without much thought about their meaning and use. Here, Benedikt Fecher and Tony Ross-Hellauer dismantle one of these metaphors of the digital society: open science. We believe that, depending on how you look at it, open science can be understood as both a tautology and an antithesis.

    The challenges of precision neutrino physics require measurements of absolute neutrino cross sections at the GeV scale with exquisite (1%) precision. This precision is presently limited by the uncertainties on neutrino flux at the source; their reduction by one order of magnitude can be achieved monitoring the positron production in the decay tunnel originating from the $K_{e3}$ decays of charged kaons in a sign and momentum selected narrow band beam. This novel technique enables the measurement of the most relevant cross sections for CP violation ($\nu_e$ and $\overline{\nu}_e$) with a precision of 1% and requires a special instrumented beam-line. Such non-conventional beam-line will be developed in the framework of the ENUBET Horizon-2020 Consolidator Grant, recently approved by the European Research Council. The project, the first experimental results on ultra-compact calorimeters that can be embedded in the instrumented decay tunnel and the advances on the simulation of the beamline are presented. We also discuss the detector and accelerator activities that are planned in 2016-2021.

    Project: EC | LOFAR (640130)

    High-energy cosmic rays, impinging on the atmosphere of the Earth initiate cascades of secondary particles, the extensive air showers. The electrons and positrons in the air shower emit electromagnetic radiation. This emission is detected with the LOFAR radio telescope in the frequency range from 30 to 240 MHz. The data are used to determine the properties of the incoming cosmic rays. The radio technique is now routinely used to measure the arrival direction, the energy, and the particle type (atomic mass) of cosmic rays in the energy range from 1017 to 1018 eV. This energy region is of particular astrophysical interest, since in this regime a transition from a Galactic to an extra-galactic origin of cosmic rays is expected. For illustration, the LOFAR results are used to set constraints on models to describe the origin of high-energy cosmic rays.
