2. 1. Monte Carlo Simulations of the Equilibrium Properties of Semi-stiff Polymer Chains : Efficient Sampling from Compact to Extended Structures

   Author : Alexey Siretskiy; Christer Elvingson; Alexander Lyubartsev; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymers; equilibrium properties; statistical mechanics; computer simulation; Monte Carlo; Wang-Landau; compact structures; parallel computations; Physical chemistry; Fysikalisk kemi; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

   Abstract : Polymers is a class of molecules which can have many different structures due to a large number of degrees of freedom. Many biopolymers, e.g. DNA, but also synthetic macromolecules have special structural features due to their backbone stiffness. READ MORE

4. 2. The role of tectonics, structures and etch processes for the present relief in glaciated Precambrian besement rocks of SW Sweden

   Author : Magnus Johansson; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landforms; morphotectonics; palaeosurfaces; GIS; digital elevation data; granite; deep weathering; saprolites; etchsurface; basins; structures; glacial reshaping; roche moutonnée; Naturgeografi; Physical Geography;

   Abstract : In high latitudes, landscapes of low relief are known to contain residues of pre-glacial deep weathering, or etching, which testify to limited modification of the pre-glacial relief by the Pleistocene ice sheets. In this thesis landforms in all scales are classified according to their process of formation. READ MORE

5. 3. Prediction of zinc-binding sites in proteins and efficient protein structure description and comparison

   Author : Nanjiang Shu; Sven Hovmöller; Elisabeth Sauer-Eriksson; Alexander Luybartsev; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc-binding; shape strings; protein structures; secondary structures; machine learning; Molecular biology; Molekylärbiologi; Biochemistry; Biokemi; Bioinformatics; Bioinformatik; Structural biology; Strukturbiologi; Biochemistry; biokemi; strukturbiologi; Structural Biology; Molecular Biology; molekylärbiologi;

   Abstract : A large number of proteins require certain metals to stabilize their structures or to function properly. About one third of all proteins in the Protein Data Bank (PDB) contain metals and it is estimated that approximately the same proportion of all proteins are metalloproteins. READ MORE

6. 4. Miniaturized Hard Waveguides in Multifunction Array Antennas

   Author : Malcolm Ng Mou Kehn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interlaced arrays; Floquet theorem; reflector antennas; focal plane array; multifunction antennas; miniaturized waveguides; multilayer structures; spectral domain technique; periodic structures; aperture reuse; method of moments; soft and hard surfaces; array antennas;

   Abstract : Recent advances in technologies of wireless communications systems have led to an increasing desire for several antennas performing diverse functions at different frequencies to be integrated into a common radiating aperture. This gives rise to the so-called multifunction antenna, which affords the saving of scarce premium real estate and can alleviate problems arising from excessive antenna protrusions in aspects such as aerodynamics, aesthetics, and stealth capability in military applications.
