Airborne wind energy resource analysis
No full textWe compare the available wind resources for conventional wind turbines and for airborne wind energy systems. Accessing higher altitudes and continuously adjusting the harvesting operation to the wind resource substantially increases the potential energy yield. The study is based on the ERA5 reanalysis data which covers a period of 7 years with hourly estimates at a surface resolution of 31 × 31 km and a vertical resolution of 137 barometric altitude levels. We present detailed wind statistics for a location in the English Channel and then expand the analysis to a surface grid of Western and Central Europe with a resolution of 110 × 110 km. Over the land mass and coastal areas of Europe we find that compared to a fixed harvesting height at the approximate hub height of wind turbines, the wind power density which is available for 95% of the time increases by a factor of two.</p

Radiative b to d Penguins
No full textThis article gives an overview of the recent searches and measurements of b {yields} d penguin transitions with the BaBar experiment. The branching fraction of these decays in the Standard Model (SM) is expected to be a factor of 10 or more lower than the corresponding b {yields} s penguin transitions, but a deviation from the SM prediction would be an equally striking sign of new physics. The exclusive decay B {yields} {pi}{ell}{ell} is searched by BaBar with no excess over the background found. The BaBar measurement of B {yields} ({rho}, {omega}){gamma} provides the first evidence of B{sup +} {yields} {rho}{sup +}{gamma}, {sup c} is in good agreement with the previous Belle results and provides a measurement of |V{sub td}/V{sub ts}| independent of the one from Bs mixing. No deviation from the SM is found
ATLAS results for Higgs and SUSY searches at the LHC
No full textThis presentation gives an overview of recent results of the ATLAS experiment in the area of SUSY searches and Higgs boson measurements. The focus lies on the interpretation of the results and on the measurement of Higgs properties. For SUSY, a short summary of inclusive searches, EW and stop production, and on final states with tau leptons is given. For the Higgs, an emphasis lies on the major results in the area of mass and coupling measurements and on constraints on invisible decays
Impact of the Euro 2020 championship on the spread of COVID-19
No full textLarge-scale events like the UEFA Euro 2020 football (soccer) championship offer a unique opportunity to quantify the impact of gatherings on the spread of COVID-19, as the number and dates of matches played by participating countries resembles a randomized study. Using Bayesian modeling and the gender imbalance in COVID-19 data, we attribute 840,000 (95% CI: [0.39M, 1.26M]) COVID-19 cases across 12 countries to the championship. The impact depends non-linearly on the initial incidence, the reproduction number R, and the number of matches played. The strongest effects are seen in Scotland and England, where as much as 10,000 primary cases per million inhabitants occur from championship-related gatherings. The average match-induced increase in R was 0.46 [0.18, 0.75] on match days, but important matches caused an increase as large as +3. Altogether, our results provide quantitative insights that help judge and mitigate the impact of large-scale events on pandemic spread
