Neural Network-based Signal Isolation and Cross Section Estimation of the tH Process with the ATLAS Detector
Kirfel, Christian (2024-02-29)A measurement of the single top quark production in association with a Higgs boson (tH) gives insight into the properties of not only the top quark but also the Higgs boson. The associated production is sensitive to the ... -
Neurale Linienselektion humaner embryonaler Stammzellen
Limbach, Nina (2012-03-29)Im Rahmen dieser Dissertation sollte ein effektives Verfahren zur Aufreinigung hESC-abgeleiteter neuronaler Populationen entwickelt werden. Hierfür wurden zwei Strategien eingesetzt. Bei der Promotor-basierten Selektion, ... -
Neuroanatomie und Funktionsmorphologie Peripherer Rezeptorneurone mit Direkten Projektionen in das Protocerebrum des Insektengehirns
Hinz, Marcel (2023-04-20)Zur Wahrnehmung unterschiedlicher thermischer Reize hat sich bei Insekten eine Reihe von Thermorezeptoren entwickelt. Der pyrophile („feuerliebend“) „Australische Feuerkäfer“ (Merimna atrata) besitzt paarige ... -
Neurobiology and modeling of cuticular hair sensilla of scorpions: Response characteristics and implications for biomimetic design
Kladt, Nikolay (2008)In this thesis, the neurobiology of mechanoreceptive sensilla on the pectines of the scorpion Pandinus cavimanus was examined. The morphology of the pectines, the innervation and morphology of the sensilla as ...

Neuroinflammation in Mausmodellen der Metachromatischen Leukodystrophie
Stein, Axel (2016-10-18)Arylsulfatase A (ASA) katalysiert die Desulfatierung von 3-O-Sulfogalaktosylceramid (Sulfatid), einem Hauptbestandteil der Myelinscheide. Ein Verlust der Aktivität von ASA führt zu der lysosomalen Speichererkrankung ... -
Neuroinvasion and cerebral ischemia as possible sources for α-synuclein prions in Parkinson’s disease
Lohmann, Stephanie (2021-07-13)In synucleinopathies such as Parkinson’s disease misfolding of α-synuclein, normally a cellular and soluble protein, leads to the accumulation of insoluble protein aggregates and to central nervous system disease (CNS). ... -
Neuronal and Circuit Architecture Underlying Feeding Behavior in Drosophila
Miroschnikow, Anton (2021-06-28)Feeding is elemental for survival and one of the most common activities of animals. Little is known about the organization of neuronal circuits controlling feeding behavior in the cen-tral nervous system. This study maps, ... -
Neuronal functions of RIM3γ and RIM4γ
Michel, Katrin (2015-09-25)The large isoforms of the Rab3 interacting molecule (RIM) family, RIM1α/β and RIM2α/β are integral components of the cytomatrix of the presynaptic active zone. Through multiple interactions with other active zone proteins ... -
Neuronal Systems Potentially Involved in Autism Spectrum Disorder
Liemersdorf, Christian (2017-06-01)Pfn2 is a brain specific actin binding protein involved in actin dynamics. The Pfn2 knock-out mouse model shows an autistic-like phenotype with all of the features commonly reported in autism patients such as social and ... -
Neuronale Netze mit erweiterten bayesschen Methoden für reale Datensammlungen
Weber, Karsten Ernst (2004)Zu zahlreichen Problemen, die bei der Verarbeitung von realen Trainingsdaten durch neuronale Netze auftreten können, und die bisher in der Literatur nicht oder nicht ausreichend diskutiert wurden, werden Lösungen präsentiert. ... -
Neuropeptides in stress reactivity: Role of enkephalin in response to chronic stress
Melo de Carvalho, Irene (2015-01-29)The incidence of mood pathologies, such as chronic anxiety and major depression, is a serious health problem in modern societies. The knowledge about the molecular mechanisms involved in the development of these disorders ... -
Neuroprotective Effects of Polysialic Acid and SIGLEC-11 in Activated Phagocytic Cells
Shahraz, Anahita (2016-03-30)SIGLEC-11 is an inhibitory receptor expressed on microglial cells and macrophages and can recognize α 2→8 linked Sias structures. The surface of neuron is decorated by different lengths of polySias. PolySia-SIGLEC-11 ... -
Die neurotoxische Wirkung von Sphingosin-1-phosphat: Mögliche Zusammenhänge zwischen Glykosphingolipid-Metabolismus und neurodegenerativen Prozessen
Hagen, Nadine (2010-11-16)Kleinhirnneuronen von S1P-Lyase-defizienten Mäusen und ein synthetischen Sphingosin Analogon wurden in dieser Arbeit verwendet, um die Toxizität von S1P, einem bioaktiven Sphingolipid, in terminal differenzierten Nervenzellen ... -
Neurotransmitter receptors in mouse models of Alzheimer’s disease
von Staden, Elena (2014-06-20)Alzheimer's disease (AD) is the most common form of dementia. The disease occurs in a common sporadic and a familiar form (FAD). Both forms show a very similar clinical and pathological picture, with ß-amyloid (Aß) plaques ... -
Neutral Atom Interactions at Surfaces, in Mixtures and Bose-Condensates
Leung, Vanessa (2007)This thesis presents, through a series of experimental and numerical results, an investigation of the collisional interactions of neutral atoms for topics of technological and scientific interest, namely, atom-surface ... -
A neutral atom quantum register
Schrader, Dominik (2005)In this thesis I present the realization of a quantum register of single neutral atoms, which is a building block of a quantum computer. It consists of a well known number of "qubits" - the quantum analogs of classical ... -
Neutral Pion Electroproduction off Light Nuclei in Chiral Perturbation Theory
Lenkewitz, Mark (2013-12-12)Threshold pion electroproduction on tri-nucleon systems is investigated in the framework of baryon Chiral Perturbation Theory (ChPT) at next-to-leading one-loop order O(q4) in the chiral expansion. To this order ... -
New Approach to Arakelov Geometry
Durov, Nikolai (2007)This work is dedicated to a new completely algebraic approach to Arakelov geometry, which doesn't require the variety under consideration to be generically smooth or projective. In order to construct such an approach we ... -
New aspects of deglaciation in southern Norway: Climate variability derived from surface exposure ages of Late Quaternary and Holocene landforms
Marr, Philipp (2020-01-30)The investigation of periglacial and related landforms in South Norway is of high interest for exploring timings of deglaciation and to assess their geomorphological connectivity to palaeoclimatic changes during the Late ... -
