"... statt um Fakten und abstrakte Prozesse ging es mal um uns.": Lehr-Lern-Projekte für Medizinstudierende in Sachsen

Die Aufnahme eines universitären Studiums bedeutet in vielerlei Hinsicht eine Umstellung. Die Studierenden müssen die Anpassung an eine neue, meist ungewohnte Lernumgebung bewältigen. Diese wartet mit einem höheren Leistungsniveau und einer komprimierten Darbietung von Lernstoff auf. Zumeist werden die Themen sehr inhaltsbezogen und in unterschiedlichen Formen unterrichtet. Eine selbständige sowie langfristige Zeitplanung ist dabei vonnöten ebenso wie selbstorganisiertes Arbeiten. Zudem sind die Unterscheidung von wichtigen und unwichtigen Inhalten sowie der Umgang mit fakultativen Veranstaltungen im Studium essenziell. Diese Kompetenzen werden zu Studienbeginn überwiegend vorausgesetzt. Die Problematik der Anpassung betrifft dabei auch und insbesondere Studierende der Medizin

Towards Experimental Handbooks in Catalysis

The “Seven Pillars” of oxidation catalysis proposed by Robert K. Grasselli represent an early example of phenomenological descriptors in the field of heterogeneous catalysis. Major advances in the theoretical description of catalytic reactions have been achieved in recent years and new catalysts are predicted today by using computational methods. To tackle the immense complexity of high-performance systems in reactions where selectivity is a major issue, analysis of scientific data by artificial intelligence and data science provides new opportunities for achieving improved understanding. Modern data analytics require data of highest quality and sufficient diversity. Existing data, however, frequently do not comply with these constraints. Therefore, new concepts of data generation and management are needed. Herein we present a basic approach in defining best practice procedures of measuring consistent data sets in heterogeneous catalysis using “handbooks”. Selective oxidation of short-chain alkanes over mixed metal oxide catalysts was selected as an example.DFG, 390540038, EXC 2008: Unifying Systems in Catalysis "UniSysCat

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
