This paper describes a named entity recognition (NER) system for short text messages (SMS) running on a mobile platform. Most NER systems deal with text that is structured, formal, well written, with a good grammatical structure, and few spelling errors. SMS text messages lack these qualities and have instead a short-handed and mixed language studded with emoticons, which makes NER a challenge on
The logistic regression model is frequently used in epidemiologic studies, yielding odds ratio or relative risk interpretations. Inspired by the theory of linear normal models, the logistic regression model has been extended to allow for correlated responses by introducing random effects. However, the model does not inherit the interpretational features of the normal model. In this paper, the auth
There is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction. Patients were evaluated with upper G
Long-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population. In this thesis I describe the utilization of a great reed warb
Microvascular surgery enables free tissue flaps to cover tissue defects, e.g. after trauma and malignancies. Although major improvements in techniques have been made, problems with poor tissue circulation and thrombus formation still exist. The aim of this thesis was to investigate the effects of hemodilution on tissue blood flow and thrombus formation in an animal model. In isovolemic hemodilutio
Though there is a very large literature examining whether energy use Granger causes economic output or vice versa this literature is fairly inconclusive. Almost all existing studies use relatively short time series or panels with a relatively small time dimension. Additionally, many recent papers continue to use what seem to be misspecified models. We apply Granger causality and cointegration tech
The thesis investigated clinical, neuroimaging and prognostic features in lacunar infarction. The studies were based on a series of 100 consequtive patients with a first-ever stroke and a lacunar syndrome investigated with CT, Gd-DTPA enhanced MRI, and with respect to large vessel disease and cardioembolic sources. the patients were followed for a mean of 4 years. MRI was repeated one year after s
The autoimmune disease Systemic Lupus Erythematosus is associated with hereditary deficieny of early components from the classical pathway of complement activation, but not with deficiency of complement component C3 or of the alternative pathway components. The classical pathway is involved in elimination of pathological immune complexes from the circulation by transport via complement receptor ty
The best mode of delivery for fetuses with intrauterine growth restriction (IUGR) and umbilical artery (UA) blood flow changes is not well elucidated. Uterine artery, fetal UA, middle cerebral artery (MCA), and venous blood flow changes during uterine contractions during an oxytocin challenge test (OCT) have not been observed systemically. AIMS: To evaluate outcome in IUGR with UA blood flow chang
Purpose of this paper The purpose of this paper is to propose a framework for describing and analyzing misalignments in supply chain management, which relate to changes in supply chain structures, processes, and management components. Design/methodology/approach Based on the systems approach, a single-case study with embedded design including several embedded cases from the same supply chain was
Antibodies are important protein structures in the immunological defence. Occasionally the regulation of the production of these antibodies fails and antibodies directed against self structures are produced in large scale. Antibody production can also complicate or make transfusions and transplantations impossible. Purified protein A from Staphylococcus aureus immobilised to beaded agarose can ads
The rapid developments within the life science and biotechnology areas put up ever-new demands on more sophisticated techniques and methods for chemical and biological analysis to reach deeper insight into the events at molecular level. Miniaturisation of assays and systems on microchips is one way to increase throughput and advance through parallel analysis lines, multiplexing and integration. Th
Popular Abstract in English Knowledge can be many things; it can be metaphysical, enhancing the understanding of human beings and social relations. It can be hard facts, information, structure and ordering of nature. Knowledge can be inherent in the knowing subject – the emancipated subject, or it can exist as an entity independent of its founder. An apposite metaphor is knowledge as an end in its
