COVID-19 pandemic providing a window of opportunity for higher education: Case study of a three-country teaching-learning experience

Aim: Since March 2020, the COVID-19 pandemic has been causing unprecedented challenges to higher education by disrupting traditional face-to-face teaching as well as international mobility of students, faculty and staff. The factual knock-out of established modes of teaching and learning and the restriction of international travel called for rapid action and a shift towards remote learning and teaching. Methods: Within the framework of a pragmatic approach, global health faculty from Fulda University of Applied Sciences in Germany and York University in Canada, including a small group of public health students from Cluj in Romania, established a globally networked learning environment. Between November and December 2020, a total of 147 students participated in joint virtual lectures and international collaborative group projects. To capture the acceptance and effectiveness of the innovative didactic experience, a semi-structured student survey was conducted directly after the last session. Results: The overall rating of internet-based cross-university teaching-learning was positive: Students reported benefits of an enriched learning experience through the sharing of different perspectives, approaches and debates with international professors and peers. Success and overcoming challenges for collaboration among students depended strongly on the level of coordination relating to time differences and expectations. Conclusion: The COVID-19 pandemic has revealed that transnational inter-university teaching-learning is feasible, provides a beneficial pedagogic option and points promising ways to the future. Conflict of interest: None declared. Acknowledgements: We gratefully acknowledge the contributions of Prof. Dr. Kai Michelsen and Prof. Dr. Marius I. Ungureanu to the development of the three-country teaching-learning experience

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
