2. 1. Issues of incompleteness, outliers and asymptotics in high dimensional data

   Author : Peter S. Karlsson; Thomas Holgersson; Ghazi Shukur; Åke E. Andersson; Jönköping University; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Business and economics; Ekonomi;

   Abstract : This thesis consists of four individual essays and an introduction chapter. The essays are in the field of multivariate statistical analysis of High dimensional data. The first essay presents the issue of estimating the inverse covariance matrix alone and when it is used within the Mahalanobis distance in High-dimensional data. READ MORE

4. 2. Carbon Emissions from Western Siberian Inland Waters

   Author : Svetlana Serikova; Jan Karlsson; Oleg S. Pokrovsky; Hjalmar Laudon; Peter Raymond; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

   Abstract : Inland waters (i.e. rivers, streams, lakes, ponds) emit carbon (C) into the atmosphere. The magnitude of global inland water C emission has been estimated to equal the global ocean C sink, thus making inland waters an important component of the global C cycle. READ MORE

5. 3. The acquisition of contrast : a longitudinal investigation of initial s+plosive cluster development in Swedish children

   Author : Fredrik Karlsson; Kirk P. H. Sullivan; Peter E. Czigler; Marilyn M. Vihman; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; phonological contrast; speech development; place and manner of articulation; aspiration; structural complexity; acoustic cues; homonym production; Phonetics; Fonetik;

   Abstract : This Thesis explores the development of word-initial s+plosive consonant clusters in the speech of Swedish children between the ages of 1;6 and 4;6. Development in the word-initial consonant clusters is viewed as being determined by 1) the children’s ability to articulate the target sequence of consonants, 2) the level of understanding of which acoustic features in the adult model production are significant for the signalling of the intended distinction, and 3) the children’s ability to apply established production patterns only to productions where the acquired feature agrees with the adult target, to achieve a contrast between rival output forms.

6. 4. Studies for Better Treatment of Patients with Glioma

   Author : Annika Malmström; Peter Söderkvist; Marie Stenmark-Askmalm; Roger Henriksson; Marit Karlsson; Ole Solheim; Linköpings universitet; []

   Abstract : In Sweden annually over 500 people will be diagnosed with the malignant brain tumor glioma. They are graded from I-IV. The majority are glioblastoma (grade IV) (GBM), these being the most aggressive type. Median survival for those treated with standard of care is expected to be around 15 months. READ MORE

7. 5. Studies on regulatory networks governing virulence gene transcription in Staphylococcus aureus

   Author : Erik Gustafsson; Högskolan i Skövde; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Naturvetenskap; Natural sciences;

   Abstract : Staphylococcus aureus pathogenicity is dependent on the coordinated action of a number of virulence factors and the expression of these virulence factors is determined by several global regulators. The main regulator seems to be agr but there are several additional regulators (mostly sarA homologues) involved that mainly act downstream of agr. READ MORE
