  1. 1. Modeling mesoscopic unconventional superconductors

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Patric Holmvall; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phase transitions; Andreev bound states; quasiclassical theory; mesoscopic thin-films; spontaneous symmetry breaking; time-reversal symmetry; Unconventional superconductivity; translational symmetry;

    Abstract : High-temperature superconducting materials are often experimentally realized as thin films that can be patterned into devices operating in the mesoscopic regime. On this length scale, various finite-size and surface effects heavily influence the nature of the superconducting state, and can induce new ground states with spontaneously broken symmetries.

  2. 2. The origin of symmetry in the metabolism of cancer – From systems biology to translational medicine

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Francesco Gatto; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cancer; systems biology; biological networks; convergent evolution; omics; metabolism; bioinformatics;

    Abstract : Why do not we have a cure for cancer yet? Cancer is the malady of the century, the most intensely studied disease of all time. The question is puzzling. It assumes that cancer is a single entity that we can target and eradicate. READ MORE

  3. 3. Control of Quasi-Equivalence in Virus Capsids

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Charlotte Helgstrand; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; crystallography; bacteriophage; virus; RNA; capsid; quasi-equivalence; assembly; Cell- och molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Many T=3 plant and insect viruses use a molecular switch in form of order/disorder of a segment of the polypeptide chain to regulate the quasi-equivalent contacts. The structure of a mutant of the T=3 capsid of bacteriophage fr confirms that this virus and other members of the Leviviridae family lack a switch mechanism. READ MORE

  4. 4. Necked-in Superdeformed Nuclei

    University dissertation from Department of Mathematical Physics, Lund University

    Author : Lars-Ove Jönsson; Lunds universitet.; Lund University.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; cranked Nilsson-Strutinsky; superdeformation; necked-in shapes; RPA; giant dipole resonance; finite-range liquid drop model; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Jönsson;

    Abstract : Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. READ MORE

  5. 5. NMR Investigations of Host-Guest Complexes and Their Dynamic Properties

    University dissertation from Stockholm : Institutionen för fysikalisk kemi, oorganisk kemi och strukturkemi

    Author : Zdenek Tosner; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supramolecular chemistry; host-guest complexes; non-covalent interactions; nuclear magnetic resonance; molecular motion; C-13 relaxation; deuterium NMR; dipolar recoupling; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi;

    Abstract : This thesis discusses several different methods offered by solution and solid state nuclear magnetic resonance for investigation of host-guest complexes and their constituents. The presented methods were used especially (but not exclusively) to address rotational dynamics of the bound guest in different molecular systems. READ MORE
