The purpose of this thesis is to augment our understanding of the Church of Yimrhane Kristos, and the Lasta period in which it was built, from the study of a variety of source materials. Due to the fact that the Lasta period suffers from the absence of adequate and reliable literary sources, this study largely depends on the elements of historic buildings as the basic data source. Using archaeomet
The light-dependent magnetic compass of birds provides orientation information about the spatial alignment of the geomagnetic field. It is proposed to be located in the avian retina, and be mediated by a light-induced, biochemical radical-pair mechanism involving cryptochromes as putative receptor molecules. At the same time, cryptochromes are known for their role in the negative feedback loop in
Objective: To describe the electrophysiological characteristics and pathophysiological significance of electrographic status epilepticus (ESE) after cardiac arrest and specifically compare patients with unequivocal ESE to patients with rhythmic or periodic borderline patterns defined as possible ESE. Methods: Retrospective cohort study of consecutive patients treated with targeted temperature mana
We extend a thermodynamically consistent finite strain micro-sphere framework elaborated by Carol et al. towards the modelling of phase-transformations to allow for the simulation of polycrystalline solids such as, e.g., shape memory alloys and shape memory polymers undergoing large deformations. The considered phase-transformation mechanism is based on statistical physics and allows the considera
Optical mapping relies on the preparation of fluorescent DNA. DNA must be imaged with good signal to noise and therefore the background of unwanted DNA fragments, fluorescent dyes and other reagents need to be removed. We use deterministic lateral displacement to separate 48.5 kbp DNA from < 10 kbp DNA. We also show the removal of 48.5 kbp DNA fragments from a background of fluorescent ATTO647N mo
Background: A complexity of factors determines outcome of foot ulcer infections in diabetic subjects. Variations in patient characteristics, treatment strategies and differences in health care systems may influence outcome. Objective: To evaluate the homogeneity in patients with diabetic foot ulcer infections of sufficient severity to warrant antibiotic treatment in three different European foot c
Reality isn’t what it appears to be. Contexts are not always clear and visible. People don’t always say what they really mean. And they don’t always mean what they say. When life is your stage manager, anything can happen. I often say, life is hard, my head is harder. Making documentaries is not for the faint-hearted.This PhD project explores creative processes and parallel realities in documentar
Popular Abstract in Swedish Retrovirus är en typ av virus som finns hos både människor och djur. Detta virus sprider sig genom att en virus partikel tar sig in i en cell och sedan integrerar sin virala arvsmassa in i cellens arvmassa, DNA. Retrovirusets arvsmassa är från början RNA men skrivs sedan om till DNA för att kunna integreras. I molekylärbiologins barndom trodde man att det genetiska flödThe human genome contains genetic elements which are more or less similar to infectious retroviruses. These are called human endogenous retroviruses (HERVs) and are thought to be remnants of infections in the primate lineage. Most of them have been inserted 10 to 60 million years ago but have at different time points spread in the genome via intracellular retrotransposition and make up as much as
Epstein-Barr virus-mediated transformation of human B lymphocytes is inhibited by human T lymphocytes as well as by interferon-γ. Removal of the inhibitory cell populations is essential in order to achieve successful transformation in vitro. Cells with the capacity to inhibit outgrowth of lymphoblastoid cell lines can be removed by pretreatment of peripheral blood mononuclear cells with l-leucyl-l
BACKGROUND: There is no consensus whether angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) should be used for secondary prevention in all or in only high-risk patients after an acute myocardial infarction (AMI).OBJECTIVES: This study sought to investigate whether ACEI/ARB treatment after AMI is associated with better outcomes across different risk profiles, inc
Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. The paper discusses a pipelined implementation that supports the handling of gray-level images at 180 to 240 Mpixels per second by exploiting the Virtex-II macros to spatially unroll the local feedback
The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di
Multiple Sclerosis (MS), is a neurologic, autoimmune disease characterized by CNS immune cell infiltration and demyelination. To experimentally study MS, we have utilized the mouse model Experimental Autoimmune Encephalomyelitis (EAE). EAE is induced through immunization with myelin antigens, which elicits an autoreactive Th1 cell response. Encephalitogenic T cells migrate into the CNS where they
This paper considers off-line optimization of a switching sequence fora given finite set of linear control systems and joint optimization ofcontrol laws. A linear quadratic full information criterion isoptimized and dynamic programming is used to find the optimalswitching sequence and control laws. The main result is a method for efficient pruning of the search tree to avoid combinatoric explosion
Our group of researchers from a variety of backgrounds has been investigating the possibility of improving vision for patients with central scotoma. So far, these patients have only been offered enlarging devices and training. We hope that new knowledge about the peripheral vision optics of the eye will result in improvements in image quality and that this can be helpful for people with low vision
We propose a technique to generate non-projective word orders in an efficient statistical linearization system. Our approach predicts liftings of edges in an unordered syntactic tree by means of a classifier, and uses a projective algorithm for tree linearization. We obtain statistically significant improvements on six typologically different languages: English, German, Dutch, Danish, Hungarian, a
