This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. This spectrum is subsequently modeled to pass thr

ABSTRACT AND INTRODUCTION Theories of text and discourse have long assumed the existence of semantic objects called discourse referents, "things being talked about and referred to by pronouns and definite noun phrases"(cf. e.g. Karttunen (1976), Sigurd (1982), Sidner (1983)). Such referents are also often alluded to in sentence grammars, above all in theories of pronominalization and control -ofte

The paper presents Referent Grammar (RG), a version of generalized phrase structure grammar. RG uses descriptive labels for defective categories (categories tacking a constituent) instead of slash expressions and needs no null (empty, zero) categories. RG uses both functional and categorial representations and the grammar rules, written in the Prolog DCG formalism, relate these two levels. The fun

Most recent publications on spin-related phenomena focus on technological aspects of spin-dependent transport, with emphasis on the specific needs of spintronics. The present publication targets rather fundamental problems related to the physics of spin in solids, such as: manifestation of spin and orbital polarization in spectroscopy, including valence and X-ray photoemission, magneto-optics, low

Popular Abstract in Swedish I hjärnan finns många olika typer av nervceller. De använder sig av olika signalsubstanser, kallade neurotransmittorer, för att kommunicera med andra nervceller. En viss typ av nervceller använder neurotransmittorn dopamin. Dopaminceller finns på många ställen i hjärnan men de flesta ligger i mellanhjärnan i ett par olika cellgrupper som var och en skickar signaler tillParkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. Clinical trials have shown that cell replacement therapy, where dopaminergic neuroblasts derived from fetal vent

To any model of brain function, the variability of neuronal spike firing is a problem that needs to be taken into account. Whereas the synaptic integration can be described in terms of the original Hodgkin-Huxley (H-H) formulations of conductance-based electrical signaling, the transformation of the resulting membrane potential into patterns of spike output is subjected to stochasticity that may n

The local well-posedness for a periodic nonlinear dispersive wave equation in compressible elastic rods is established. Blow-up of solutions in finite time is obtained, provided their initial data satisfy certain conditions. (C) 2003 Elsevier Inc. All rights reserved.

PURPOSE: To investigate the impact of COVID-19 in Sweden on rates of knee and hip surgeries.METHODS: We used healthcare data for the population of the southernmost region in Sweden (1.4 million inhabitants). We did an interrupted time-series analysis to estimate changes in rates and trends of joint replacements (JR), arthroscopies, and fracture surgeries for knee or hip in April-December 2020 comp

A measurement of observables sensitive to spin correlations in tt¯ production is presented, using 36.1 fb - 1 of pp collision data at s=13 TeV recorded with the ATLAS detector at the Large Hadron Collider. Differential cross-sections are measured in events with exactly one electron and one muon with opposite-sign electric charge as a function of the azimuthal opening angle and the absolute differe

The demand for fast and energy efficient (opto-)electronic applications needs high mobility semiconductor materials, such as InAs with a very high electron mobility and GaSb with a very high hole mobility. Beyond the material itself, also an innovative device geometry is needed, for example, the gate-all-around geometry that provides higher efficiency and electrostatic control for computational un
