Strukturierung eines Verkehrsnetzes: Verkehrsgeographische Untersuchungen unter Verwendung graphentheoretischer Ansätze am Beispiel des süddeutschen Eisenbahnnetzes
(1979)Diese Arbeit befaßt sich mit der "Struktur" von Verkehrsnetzen. Vermittels eines stark formalisierten Ansatzes der Graphentheorie wird am Beispiel des Eisenbahnnetzes von Süddeutschland gezeigt, daß "Struktur" nicht als ... -
Convergence analysis of online algorithms for vector-valued kernel regression
(2023-09)We consider the problem of approximating the regression function from noisy vectorvalued data by an online learning algorithm using an appropriate reproducing kernel Hilbert space (RKHS) as prior. In an online algorithm, ... -
Convergence of generalized cross-validation for an ill-posed integral equation
(2023-12)In this article we rigorously show consistency of generalized cross-validation applied to an exemplary ill-posed integral equation, given a finite number of noisy point evaluations. In particular, we present non-asymptotic ... -
Data Science with Foundation Models: An Evidence-Based, Comprehensive Project Methodology
(2024-05-23)In the past decades, the interest in data science has surged across sectors and industries. Data science has been impacted by a series of paradigm shifts, such as the emergence of big data, cloud computing or the demand ... -
The Effect of Ivy Leaf Dry Extract EA 575® on the Signalling of Adenosine Receptor A2B
(2024-05-23)Ivy leaf dry extract EA 575<sup>®</sup> is used to alleviate the symptoms associated with chronic inflammatory bronchial diseases and acute inflammation of the respiratory tract accompanied by coughing. Its mechanism of ... -
Alzheimer’s and inflammation: exploring the interplay between immune cells in the peripheral immune system and the central nervous system through single-cell RNA-seq
(2024-05-23)Alzheimer’s disease (AD) is a progressive neurodegenerative disease that is the most common cause of dementia and the sixth leading cause of death globally (Haque & Levey, 2019; World Health Organization, 2017). Increases ... -
Die horizontale und vertikale Verbreitung der Vegetation im Himalaya
(1957)The idea of attempting a geographical survey of the vegetation of the Himalayas was conceived when in 1937 Professor C. TROLL was travelling in the north-western and eastern parts of the hills (Nanga Parbat, Sikkim). The ... -
Efficient solution of ill-posed integral equations through averaging
(2024-01)This paper discusses the error and cost aspects of ill-posed integral equations when given discrete noisy point evaluations on a fine grid. Standard solution methods usually employ discretization schemes that are directly ... -
Biopharmaceutical characterization and formulation development of poorly water-soluble phytochemicals using in vivo predictive biphasic dissolution
(2024-05-22)Nature offers a vast variety of different substances, some of which are known to have health-beneficial effects on humans. Thus, many of these compounds are frequently used as dietary supplements or herbal medicinal products. ... -
Neue Cities australischer Metropolen: Die Entstehung multifunktionaler Vorortzentren als Folge der Suburbanisierung
(1996)Wie in zahlreichen Metropolen anderer Industrienationen lassen sich auch in den größeren australischen Verdichtungsräumen Dekonzentrationsprozesse verschiedener ökonomischer Aktivitäten betrachten. Im Hinblick auf die ... -
Vegetationskundliche Untersuchungen an südchilenischen Vulkanen
(1985)An verschiedenen Vulkanen Süd-Chiles (Vulkan Llaima, Quetropillan, Mocho-Choshuenco, Puyehue, Antillanca, Osorno, Puntiagudo und Cerro Riggi) wurden von 1980 bis 1982 die andin verbreiteten Pflanzen gesellschaften soziologisch ... -
Charakterisierung der NLRP3-abhängigen und -unabhängigen IL-1β-Freisetzung in Makrophagen
(2024-05-22)Interleukin (IL)-1β ist ein primärer Botenstoff, der für die Vermittlung von Entzündungen verantwortlich ist und damit eine zentrale Rolle bei zahlreichen Krankheiten spielt. Bisher wird die IL-1β-Freisetzung allerdings ... -
G protein-coupled receptors mobilize intracellular calcium via the Gs-βγ-PLCβ module
(2024-05-22)Accurate regulation of calcium is essential for many physiological processes. To fine-tune these processes, the cell can draw on a large portfolio of diverse mechanisms to govern calcium mobilization, in which GPCRs present ... -
Order-Theoretic Combination Techniques and the Electronic Schrödinger Equation
(2024-05-22)Most standard constructions of the <em>combination technique</em> [M. Griebel et al., <em>Iterative Methods in Linear Algebra</em>, Elsevier, North Holland, p. 263] manipulate families of functions organised by downward-closed ... -
Florengeographische Untersuchungen im Raume der Sahara: Ein Beitrag zur pflanzengeographischen Differenzierung des nordafrikanischen Trockenraumes
(1978)Die vorliegende Arbeit ist ein Versuch, die räumliche Anordnung der Pflanzenwelt in der Sahara floristisch zu analysieren. -
Analyse und Parametrisierung von Landnutzungseigenschaften zur Modellierung von Abfluss, Bodenerosion und Sedimentation im Einzugsgebiet des Wahnbachs (Bergisches Land)
(2011)In dieser Arbeit wurden mit Hilfe einer gekoppelten Modellanwendung der Abfluss, die Bodenerosion und die Sedimentation für das 54 km<sup>2</sup> große Einzugsgebiet des Wahnbachs (Bergisches Land) analysiert. -
The yeast prion domain Sup35 NM models features of human neurodegenerative diseases in vivo
(2024-05-21)In neurodegenerative diseases, such as prion diseases and Alzheimer’s disease, disease- associated proteins misfold and form amyloid deposits that progressively invade the CNS, leading to severe neurodegeneration. Accumulating ... -
Theoretical Studies of Nuclear Magnetic Resonance Chemical Shifts
(2024-05-21)Nuclear magnetic resonance (NMR) spectroscopy is among the most important analytical methods for the determination of the chemical structure of matter. Its versatile applicability leads to the necessity of reliable ... -
