High-resolution spectroscopy of gaseous 83m Kr conversion electrons with the KATRIN experiment
No full text© 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
No full textThe 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

A Probabilistic Analysis of Lahar Bulking and Debulking in Channelized Proximal Volcanic Settings
No full textThis item is available only to currently enrolled UTSA students, faculty or staff. To download, navigate to Log In in the top right-hand corner of this screen, then select Log in with my UTSA ID.Lahars are gravitationally driven mudflows that occur on volcanic slopes and pose a significant threat to communities located downslope. The initial stages of their evolution, particularly bulking and debulking, within the proximal hazard zone are understudied and poorly understood. The goal of this study is to investigate the relationship between certain geometric channel characteristics and field observations of bulking and debulking from a 2012 lahar along a section of the Jamapa watershed, located within the proximal zone of the Pico de Orizaba. Drone acquired Digital Elevation Models (DEMs) were used to extract the geometric channel characteristics. The relationships were then investigated by developing logistic regression models with bulking and debulking as dependent variables and the 14 independent variables. When used in a multivariate model, these models show that lithology, channel width, and channel shapes are significantly related to observations of bulking and debulking, whereas slope, sinuosity, average catchment slope, and watershed contributing area are not. Although the models developed here are based on variables related to channel geometry and a single lahar event, this author recommends additional variables related to the physical characteristics of lahar flow itself be incorporated into future models. This could help improve its predictive capability and resolve issues related to abnormally small parameter estimates. Even though the models' results are far from perfect, they provide a foundation for developing more complex models that could advance our understanding of lahar evolution during the early stages that could be used to improve lahar flow models in the future.Geoscience
The haunted public sphere: women and the power of emotion in the works of Alexander Kluge and the films of the Berlin School
No full textMy dissertation sheds light on the German filmmaker and author Alexander Kluge and his ideas on filmmaking as they evolved out of his conception of the public versus the private spheres since the early 1960s. It was Kluge’s contention that personal experiences of war and violence could not be expressed publicly in the postwar Federal Republic, causing a rift between the two realms and a haunting presence of trauma within individuals and society as a whole. What Kluge, in cooperation with Oskar Negt, called “alternative public sphere” in Public Sphere and Experience (1972) and History and Obstinacy (1981) is closely linked to Woman and so-called “proletarian” forces countering instrumental reason and the bourgeois cultural matrix. Analyzing four crucial films from Kluge’s creative work, I outline the increasingly allegorical role of his concept of “female mode of production,” which constitutes Kluge’s aesthetics and thematic focus. How the ideas of “alternative public sphere” and “female mode of production” are linked to the cinema and Kluge’s theory of film is the focus of another chapter that scrutinizes Kluge’s recent literary compilation Cinema Stories (2007). Finally, I read a selection of contemporary German films considered the new filmic avant-garde through the lens of Kluge’s approach to film, to the “female mode of production,” and to the public sphere. This allows me to compare the ethics, the formal and political attitude of the so-called Berlin School directors to the vanguard movement of Young German Film in the sixties and early seventies. I conclude that the filmic Autoren today deal with a similar problem as Alexander Kluge has done throughout his career, namely the dissociation of personal, lived experience from public representation. They also employ formal and thematic strategies that can be related to the thoughts behind the Oberhausen generation of German filmmakers. While the generation of the leftist student movements sought public recognition of the atrocities committed under National Socialism, the Berlin School directors deal with mediated experience in times of media and finance corporatism as virtual realities threaten to take over the empiric world.Ph.

Thoughts on the Importance of the Meso Perspective: the “ Plattform Produktives Stadtgrün” / Gedanken zur Bedeutung der Mesoperspektive: „Plattform Produktives Stadtgrün“
No full textInvited to contribute to a book section on Berlin, Katrin Bohn thinks about the importance of a middle ground between the big pressing macro questions of climate change and the micro spaces of individual food system activities. She writes: ‘Judging by the realities of environmental degradation, traditional urban planning has failed. Concerns of experts have not been sufficiently acknowledged. It requires a middle ground—a meso perspective—to better enable conversation between the various urban stakeholders and bring about widely supported and lasting change. How can this be initiated? In a time of social media, the author proposes to look at a recently developed tool for information, communication, networking, and—ultimately—urban planning’.Bohn uses the Plattform Produktives Stadtgrün [Plattform Productive Urban Green], a Berlin-based interactive online tool developed in a collaboration between the local council, local community gardeners and external experts, including Katrin, to illustrate such a meso perspective.The book Urban Open Space + is edited by Carolin Mees and published by Jovis. Subtitled Strategies inbetween architecture and open space planning, the bi-lingual publication (English/German) explores ‘commonly used and designed open spaces [as] anchor points in the city and a possible response to the consequences of urbanization and climate change, as well as to the presence of social and cultural differences’
