1. 6. Exploring the Boundaries of Gene Regulatory Network Inference

   Författare :Andreas Tjärnberg; Erik Sonnhammer; Richard Bonneau; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GRN; gene regulatory network; network inference; signal to noise ratio; model selection; variable selection; data properties; reverse engineering; ordinary differential equations; gene networks; linear regression; lasso; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Sammanfattning : To understand how the components of a complex system like the biological cell interact and regulate each other, we need to collect data for how the components respond to system perturbations. Such data can then be used to solve the inverse problem of inferring a network that describes how the pieces influence each other. LÄS MER

3. 7. Evolution of the Biodiversity Hotspot of Madagascar from the Eye of Diving Beetles : Phylogeny, colonization and speciation

   Författare :Rasa Bukontaite; Johannes Bergsten; Ingi Agnarsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dytiscidae; diving beetles; Biogeography; Phylogeny; Dating; phylogenetic informativeness; colonization; speciation; microendemism; Madagascar; systematisk zoologi; Systematic Zoology;

   Sammanfattning : Dytiscidae, contains numerous endemic and non-endemic species on Madagascar. Their evolutionary history is largely unknown on the island. Herein, I use analyses to infer phylogenetic relationship among groups of diving beetles, with a focus on the subfamily Dytiscinae and endemic species in two other groups of Dytiscidae. LÄS MER

4. 8. Model calibration methods for mechanical systems with local nonlinearities

   Författare :Yousheng Chen; Andreas Linderholt; Thomas Abrahamsson; Gaëtan Kerschen; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model calibration; finite element modelling; nonlinear structural dynamics; pre-test planning; multi-sinusoidal excitation; vibrational testing; cross validation; Maskinteknik; Mechanical Engineering;

   Sammanfattning : Most modern product development utilizes computational models. With increasing demands on reducing the product development lead-time, it becomes more important to improve the accuracy and efficiency of simulations. LÄS MER

5. 9. Population Genetic Methods and Applications to Human Genomes

   Författare :Lucie Gattepaille; Mattias Jakobsson; Kevin Thornton; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Human evolution; Genetic diversity; Genetic differentiation; Adaptation; Population structure; Effective population size; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Population Genetics has led to countless numbers of fruitful studies of evolution, due to its abilities for prediction and description of the most important evolutionary processes such as mutation, genetic drift and selection. The field is still growing today, with new methods and models being developed to answer questions of evolutionary relevance and to lift the veil on the past of all life forms. LÄS MER

7. 10. Assessments of Advertisements on Social Networking Sites

   Författare :Hossam Deraz; Gabriel Awuah; Klaus Søilen; Gerson Tontini; Tim Foster; Högskolan i Halmstad; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Internet Marketing; Advertisements; Social networking sites; Assessment of advertisements; National Culture; Brand communities;

   Sammanfattning : Advertisements (ads) in social networking sites (SNSAs) have been considered by many researchers as a crucial area of research. However, the scope of the existing studies on consumers’ assessments of SNSAs has been very limited. LÄS MER
