High-resolution spectroscopy of gaseous 83m Kr conversion electrons with the KATRIN experiment
© 2020 The Author(s). Published by IOP Publishing Ltd. In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous 83mKr with the Karlsruhe Tritium Neutrino (KATRIN) experiment. The obtained results represent one of the major commissioning milestones for the subsequent direct neutrino mass measurement with KATRIN. The successful campaign demonstrates the functionalities of the KATRIN beamline. Precise measurement of the narrow K-32, L3-32, and N2,3-32 conversion electron lines allowed to verify the eV-scale energy resolution of the KATRIN main spectrometer necessary for competitive measurement of the absolute neutrino mass scale

KATRIN: Status and Prospects for the Neutrino Mass and Beyond
The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a
high-precision integral spectrum of the endpoint region of T2 beta decay, with
the primary goal of probing the absolute mass scale of the neutrino. After a
first tritium commissioning campaign in 2018, the experiment has been regularly
running since 2019, and in its first two measurement campaigns has already
achieved a sub-eV sensitivity. After 1000 days of data-taking, KATRIN's design
sensitivity is 0.2 eV at the 90% confidence level. In this white paper we
describe the current status of KATRIN; explore prospects for measuring the
neutrino mass and other physics observables, including sterile neutrinos and
other beyond-Standard-Model hypotheses; and discuss research-and-development
projects that may further improve the KATRIN sensitivity.Comment: Contribution to Snowmass 2021. 70 pages excluding references; 35

Spielend Lehrer/in werden: problembasiertes Lernen mit virtuellen Schülerinnen/Schülern
Über das Lehramtsstudium sollen Studierende unter anderem dazu befähigt werden, die Leistung ihrer Schüler/innen zu bewerten. Dazu müssen sie Einflussfaktoren auf Schulleistung kennen und diese richtig diagnostizieren und fördern können. Mit diesem Beitrag wird eine game- und E-Learning-gestützte Lernumgebung vorgestellt, in der Studierende – anders als in vielen inputorientierten Seminarkonzepten – in einem virtuellen Klassenzimmer an realitätsnahen Fällen lernen, problembasiert zu diagnostizieren und zu fördern. Über den Einsatz der Lernumgebung in der Lehre wird berichtet, erste Rückmeldungen von Lehrenden und Studierenden werden erläutert und weitere Planungsschritte dargestellt.

Über die Hitze in der Stadt
Auf der ganzen Welt arbeiten Wissenschaftler und Architekten daran, Metropolen zu kühlen. Denn gerade im Sommer bilden sich in Städten Hitzeinseln, die eine wachsende Belastung für die Bevölkerung darstellen. Stadtklima-Expertin Katrin Hagen von der Technischen Uni Wien erforscht, wie es dazu kommt, dass das Stadtklima dem normalen Klimawandel voraus eilt und wie man entsprechende Maßnahmen dagegen findet. Saskia Jungnikl-Gossy spricht mit ihr über die Hitze in der Stadt, warum Städte von der Klimakrise besonders stark betroffen sind, welche Lösungen machbar sind und in welchen Städten die kreativsten Lösungen gefunden werden
Disturbed prefrontal and temporal brain function during emotion and cognition interaction in criminal psychopathy
Impaired emotional responsiveness has been revealed as a hallmark of psychopathy. In spite of an increasing database on emotion processing, studies on cognitive function and in particular on the impact of emotion on cognition in psychopathy are rare. We used pictures from the International Affective Picture Set (IAPS) and a Simon Paradigm to address emotion-cognition interaction while functional and structural imaging data were obtained in 12 healthy controls and 10 psychopaths. We found an impaired emotion-cognition interaction in psychopaths that correlated with a changed prefrontal and temporal brain activation. With regard to the temporal cortex, it is shown that structure and function of the right superior temporal gyrus is disturbed in psychopathy, supporting a neurobiological. approach to psychopathy, in which structure and function of the right STG may be important.

Emotion-dependent modulation of interference processes: an fMRI study.
We studied the effects of experimentally induced emotions on inhibitory control using functional magnetic resonance tomography (fMRI). The Simon task used involves two conditions with different attentional demands and is a well established paradigm for studying inhibitory control. Incompatible trials demand cognitive control for resolving interference. Compatible trials need no inhibitory control. Twelve participants viewed a series of affective pictures inducing positive, negative or neutral affects. Between the picture blocks, participants performed either incompatible or compatible trials. Behavioral and fMRI data revealed an impact of negative emotions only on the processing of ncompatible trials. Subjects made more errors and showed less activation of brain areas associated with task performance. There was no effect of positive emotions neither on compatible nor incompatible trials. The results first showed that especially the processing of negative emotions is resource competing and secondly that the competition concerns only the controlled route of cognitive processing
