2. 1. Mathematical Modelling of Cell Migration and Polarization

   Author : Adam Malik; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Cell migration plays a fundamental role in both development and disease. It is a complex process during which cells interact with one another and with their local environment. Mathematical modelling offers tools to investigate such processes and can give insights into the underlying biological details, and can also guide new experiments. READ MORE

4. 2. Evolution of Plants : a mathematical perspective

   Author : Magnus Lindh; Åke Brännström; Jacob Johansson; Mats G Larson; Lennart Persson; Claus Rüffler; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolution; plants; mathematics; optimization; optimal control; adaptive dynamics; flowering; seasons; tree crown; drought; taproot; trade-off; strategy; trait; ESS; NPP; LAI; Red Queen; Mathematics; matematik;

   Abstract : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. READ MORE

5. 3. Hidden patterns that matter : statistical methods for analysis of DNA and RNA data

   Author : Therese Kellgren; Patrik Rydén; Sara Sjöstedt de Luna; Rebecka Jörnsten; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Genome; Next-generation sequence; statistics; microarrays; bacteria; antibiotic resistance; inherited diseases; Co-expression networks; centralization within subgroups;

   Abstract : Understanding how the genetic variations can affect characteristics and function of organisms can help researchers and medical doctors to detect genetic alterations that cause disease and reveal genes that causes antibiotic resistance. The opportunities and progress associated with such data come however with challenges related to statistical analysis. READ MORE

6. 4. Pedagogic practice between tradition and renewal : A study of the new mathematics curriculum in Mozambique

   Author : Balbina Mutemba; Candia Morgan; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

   Abstract : The new school mathematics curriculum in Mozambique, introduced in 2008, is partly competency-based and it advocates a more student-centred pedagogy. The most salient innovative features are the incorporation of mathematical competencies related to the development of students’ reasoning skills, including argumentation, justification and analytical thinking, and the use of heuristic or inductive methods that promote meaningful students’ participation.

7. 5. Inbreeding, Effective Population Sizes and Genetic Differentiation : A Mathematical Analysis of Structured Populations

   Author : Fredrik Olsson; Ola Hössjer; Steinar Engen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; matematisk statistik; Mathematical Statistics;

   Abstract : This thesis consists of four papers on various aspects of inbreeding, effective population sizes and genetic differentiation in structured populations, that is, populations that consist of a number of subpopulations. Three of the papers concern age structured populations, where in the first paper we concentrate on calculating the variance effective population size (NeV) and how NeV depends on the time between measurements and the weighting scheme of age classes.
