1. Channel Shortening in Wireless Communication
Sammanfattning : The concept of Channel Shortening (CS) is a well-known technique that has a rich history over 40 years. CS transfers linear vector channels such as multi-input multi-output (MIMO) and intersymbol interference (ISI) channels into ``shortened'' versions, for the purpose of reducing demodulation-complexity and improving data-transmission performance.

2. The Effect of Mechanical Characteristics of Basal Decollement and Basement Structures on Deformation of the Zagros Basin
Sammanfattning : Two fundamental structural elements, basement architecture and basal decollement, play a significant role in the evolution of a tectonically active region. Using different approaches (field data, literature review and analogue models) this thesis demonstrates that these two elements affected the deformation style in the Zagros fold-thrust belt during Mesozoic extensional and Cenozoic contractional episodes.

3. Variability and adaptation in the contractile system of smooth muscle
Sammanfattning : This thesis examines the cellular and molecular mechanisms involved in the large diversity of the contractile properties in smooth muscle. Six studies, I-VI, are included. I: a slow smooth muscle (aorta) has a different nucleotide and phosphate dependence compared to a fast type (taenia coli). LÄS MER
4. Studies in Latvian Comparative Dialectology : —with special focus on word-final *–āj(s)/*–ēj(s) and *–āji(s)/*–ēji(s)
Sammanfattning : The thesis consists of four interconnected studies of various topics in the fields of Latvian dialectology and historical linguistics: (1) apocope and shortening; (2) loss of the present 2nd singular endings *?i and *??; (3) the development of the participle desinences *??jis *??jis; (4) the ??�and ??stem locative singular endings. A recurrent theme is a potential loss of *j in the phonological sequences *??ji(s) *??ji(s), which were subsequently contracted to *??j(s) *??j(s). LÄS MER
5. On the way of making plants smell like moths - a synthetic biology approach
Sammanfattning : Moth caterpillars are major agricultural pests in many parts of the world. In general female moths attract male mates with their pheromone over long distance. Most of the described moth pheromones belong to the same class of chemical compounds, fatty acid derivatives that are produced de novo in the pheromone gland. LÄS MER
