    We continue our research on perversely awful randomized algorithms, which started nearly a decade ago. Based on the bogo-method we design a bogo-selection algorithm and variants thereof and analyse them with elementary methods. Moreover, practical experiments are performed

    Global value chains: Potential synergies between external trade policy and internal economic initiatives to address the strategic dependencies of the EU

    Get PDF
    Global value chains enable two-thirds of international trade, notably for the EU. The EU wants to preserve its commercial links with third countries and organisations to make up for trade disruptions. This study examines sustainable supply of raw materials, commodities, and critical goods using the EU's Open Strategic Autonomy concept. It examines which raw material are crucial for sustainable supply and necessary for the green transition. The paper examines EU internal legislation and international cooperation instruments to determine the EU's disruption risk. It evaluates the economic impact of EU preferential trade agreements on raw material availability. The study illustrates the political and economic relevance of raw material partnerships and plurilateral and bilateral trade agreements. It analyses the EU's toolbox for safeguarding its interests and making independent trade choices to counteract other actors' unfair practices and intervention. Finally, the paper examines regulatory frameworks, international alliances, and activities to find ways to strengthen global value chains in critical EU industries

    Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

    Get PDF
    We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation, compare the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
