  2. 11. Protein Folding Studies on the Ribosomal Protein S6: the Role of Entropy in Nucleation

    Author : Magnus Lindberg; Mikael Oliveberg; Jane Clarke; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; protein folding; circular permutation; topology; connectivity; entropy; protein stability; chevron plot; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : One of the most challenging tasks remaining in the field of biochemistry is the one of understanding how the information within the amino acid sequence of proteins translates into a unique structure. Solving this problem would lead to endless possibilities for application in the medical and biotechnology industry. READ MORE

  4. 12. Permutation Patterns, Continued Fractions, and a Group Determined by an Ordered Set

    Author : Anders Claesson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : We present six articles: In the first and second article we give the first few results on generalized pattern avoidance, focusing on patterns of type (1,2) or (2,1). There are twelve such patterns, and they fall into three classes with respect to being equidistributed. We use 1-23, 1-32, and 2-13 as representatives for these classes. READ MORE

  5. 13. Computational Medical Image Analysis : With a Focus on Real-Time fMRI and Non-Parametric Statistics

    Author : Anders Eklund; Hans Knutsson; Mats Andersson; Stephen LaConte; Linköpings universitet; []
    Keywords : functional magnetic resonance imaging; brain computer interfaces; canonical correlation analysis; random permutation test; graphics processing unit;

    Abstract : Functional magnetic resonance imaging (fMRI) is a prime example of multi-disciplinary research. Without the beautiful physics of MRI, there wouldnot be any images to look at in the first place. To obtain images of goodquality, it is necessary to fully understand the concepts of the frequencydomain. READ MORE

  6. 14. Sequences and games generalizing the combinatorial game of Wythoff Nim

    Author : Urban Larsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blocking manoeuvre; Beatty sequence; Combinatorial game; Complementary sequences; Impartial game; Interspersion array; Muller twist; Nim; Permutation of the natural numbers; Stolarsky array; Wythoff Nim; Beatty sequence;

    Abstract : One single Queen is placed on an arbitrary starting position of a (large) Chess board. Two players alternate in moving the Queen as in a game of Chess but with the restriction that the $L^1$ distance to the lower left corner, position $(0,0)$, must decrease. The player who moves there wins. Let $\phi =\frac{1+\sqrt{5}}{2}$, the golden ratio. READ MORE

  7. 15. Crystallographic studies of transaldolase : implications for the enzymatic mechanism and the evolution of class I aldolases

    Author : Jia Jia; Karolinska Institutet; Karolinska Institutet; []
    Keywords : transaldolase; aldolase; Schiff-base intermediate; protein crystallography; site directed mutagenesis; catalytic mechanism; circular permutation.;

    Abstract : Transaldolase catalyzes the reversible transfer of a dihydroxyacetone moiety from a ketose donor to an aldose acceptor by forming a Schiff-base intermediate between a Iysine residue and dihydroxyacetone. It belongs to the class I aldolase family. READ MORE
