    In her dissertation Revealing Śiva’s Superiority by Retelling Viṣṇu’s Deeds – Viṣnu’s Manifestation Myths in the Skandapurāṇa, Sanne Dokter-Mersch examines three myths in the Skandapurāṇa, a Sanskrit Purāṇa composed in the sixth to seventh century. Although myths about god Śiva and devotion to him are central in the text, it also contains narratives about other gods. This dissertation focusses on those myths in which god Viṣṇu manifests himself as Man-Lion (Narasiṃha), Boar (Varāha) and Dwarf (Vāmana) in order to conquer the enemies of the gods. At the time of composition of the Skandapurāṇa, Śiva and Viṣṇu each had their own religious ideology and devotees, which raises the questions why the composers of this Śaiva Purāṇa dedicated so much attention to Viṣṇu and how these manifestation myths are retold. With the help of different (narratological) methods, Dokter-Mersch addresses these questions by looking at the manifestation myths as part of a literary genre, the Purāṇas.Asian Studie

    Radar Instance Transformer: Reliable Moving Instance Segmentation in Sparse Radar Point Clouds

    The perception of moving objects is crucial for autonomous robots performing collision avoidance in dynamic environments. LiDARs and cameras tremendously enhance scene interpretation but do not provide direct motion information and face limitations under adverse weather. Radar sensors overcome these limitations and provide Doppler velocities, delivering direct information on dynamic objects. In this paper, we address the problem of moving instance segmentation in radar point clouds to enhance scene interpretation for safety-critical tasks. Our Radar Instance Transformer enriches the current radar scan with temporal information without passing aggregated scans through a neural network. We propose a full-resolution backbone to prevent information loss in sparse point cloud processing. Our instance transformer head incorporates essential information to enhance segmentation but also enables reliable, class-agnostic instance assignments. In sum, our approach shows superior performance on the new moving instance segmentation benchmarks, including diverse environments, and provides model-agnostic modules to enhance scene interpretation. The benchmark is based on the RadarScenes dataset and will be made available upon acceptance.Comment: UNDER Revie

    Echterhoff D, Grasmugg S, Mersch S, Mönckemeyer M, Spitta T, Wrede S. Die Evolution einer Standardarchitektur für Betriebliche Informationssysteme. In: Spitta T, Borchers J, Sneed HM, eds. Software-Management 2002. LNI. Vol P-23. Bonn: GI e.V.; 2002: 131-142.The paper outlines the history of a standard architecture for small and medium sized administrative systems. It has been developped 1985 in the Schering AG / Berlin, and applied in several firms over more than 15 years. Some of the about 150 applications, developped and maintained by more than 100 programmers, are still in operation. In 1999 a revision of the architecture and a new implementation in Java was started. The latest version is a four-level-architecture for distributed systems with a browser as user interface. Aside architectural considerations we discuss some of our design and implementation experiences with java

    Characteristics of transposable element exonization within human and mouse

    Insertion of transposed elements within mammalian genes is thought to be an important contributor to mammalian evolution and speciation. Insertion of transposed elements into introns can lead to their activation as alternatively spliced cassette exons, an event called exonization. Elucidation of the evolutionary constraints that have shaped fixation of transposed elements within human and mouse protein coding genes and subsequent exonization is important for understanding of how the exonization process has affected transcriptome and proteome complexities. Here we show that exonization of transposed elements is biased towards the beginning of the coding sequence in both human and mouse genes. Analysis of single nucleotide polymorphisms (SNPs) revealed that exonization of transposed elements can be population-specific, implying that exonizations may enhance divergence and lead to speciation. SNP density analysis revealed differences between Alu and other transposed elements. Finally, we identified cases of primate-specific Alu elements that depend on RNA editing for their exonization. These results shed light on TE fixation and the exonization process within human and mouse genes.Comment: 11 pages, 4 figure

    Erarbeitung betriebsindividueller Handlungsempfehlungen zur Verbesserung der Euter- und Stoffwechselgesundheit im Rahmen einer interdisziplinären Interventionsstudie

    Kernziel des im Rahmen des Bundesprogramms Ökologischer Landbau initiierten Forschungsvorhabens „Gesundheit und Leistungsfähigkeit von Milchkühen im ökologischen Landbau interdisziplinär betrachtet“ (FKZ 07OE012 - 07OE022) ist - neben der Abschätzung des Risikos für Stoffwechselstörungen und Eutererkrankungen - die Entwicklung eines praxistauglichen, präventiv orientierten Tiergesundheitsmanagements für die Praxis der ökologischen Milchviehhaltung. Basierend auf einer Interventionsstudie auf 106 repräsentativ ausgewählten Milchviehbetrieben soll dieses Managementkonzept in einer zweijährigen Praxisphase validiert und auf seine Praxistauglichkeit überprüft werden. Als Grundlage für die Identifikation einzelbetrieblicher Interventionsmaßnahmen dienen zentrale Indikatoren der Euter- und Stoffwechselgesundheit, deren Abgleich mit im Vorfeld definierten Zielgrößen sowie Informationen zur Haltungsumwelt und zum Herdenmanagement. Das entwickelte Konzept soll eine einzelbetriebliche Einschätzung des Gesundheitsstatus der Milchviehherde bezüglich der Euter- und Stoffwechselgesundheit ermöglichen, auf deren Basis Handlungsempfehlungen zur nachhaltigen Verbesserung der Milchviehgesundheit abgeleitet werden können. Die Projektbetriebe setzten zwei Drittel der empfohlenen Maßnahmen um; eine abschließende Effektivitätskontrolle in Bezug auf die Verbesserung der Euter- und Stoffwechselgesundheit auf den Betrieben auf Basis der Daten des letzten Projektjahres steht noch aus

    Seasonality in depressive and anxiety symptoms among primary care patients and in patients with depressive and anxiety disorders; results from the Netherlands Study of Depression and Anxiety

    <p>Abstract</p> <p>Background</p> <p>Little is known about seasonality of specific depressive symptoms and anxiety symptoms in different patient populations. This study aims to assess seasonal variation of depressive and anxiety symptoms in a primary care population and across participants who were classified in diagnostic groups 1) healthy controls 2) patients with a major depressive disorder, 3) patients with any anxiety disorder and 4) patients with a major depression and any anxiety disorder.</p> <p>Methods</p> <p>Data were used from the Netherlands Study of Depression and Anxiety (NESDA). First, in 5549 patients from the NESDA primary care recruitment population the Kessler-10 screening questionnaire was used and data were analyzed across season in a multilevel linear model. Second, in 1090 subjects classified into four groups according to psychiatric status according to the Composite International Diagnostic Interview, overall depressive symptoms and atypical versus melancholic features were assessed with the Inventory of Depressive Symptoms. Anxiety and fear were assessed with the Beck Anxiety Inventory and the Fear questionnaire. Symptom levels across season were analyzed in a linear regression model.</p> <p>Results</p> <p>In the primary care population the severity of depressive and anxiety symptoms did not show a seasonal pattern. In the diagnostic groups healthy controls and patients with any anxiety disorder, but not patients with a major depressive disorder, showed a small rise in depressive symptoms in winter. Atypical and melancholic symptoms were both elevated in winter. No seasonal pattern for anxiety symptoms was found. There was a small gender related seasonal effect for fear symptoms.</p> <p>Conclusions</p> <p>Seasonal differences in severity or type of depressive and anxiety symptoms, as measured with a general screening instrument and symptom questionnaires, were absent or small in effect size in a primary care population and in patient populations with a major depressive disorder and anxiety disorders.</p
