  2. 1. Theory of water-proton spin relaxation in complex biological systems

    Author : Zhiwei Chang; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin relaxation theory; immobilized macromolecules; magnetic relaxation dispersion; integral longitudinal relaxation rate; stochastic Liouville equations; multi-spin systems; cross-mode relaxation; spectral density functions;

    Abstract : In complex biological systems (e.g. gels, cross-linked proteins and biological tissues), the longitudinal spin relaxation of water protons is primarily induced by exchange-mediated orientational randomization (EMOR) of intra- and intermolecular magnetic dipole-dipole couplings.

  4. 2. Extended Computational Module for Tractive Effort at Rolling and Spinning Point Contacts

    Author : Mikael Törmänen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spin; thermal effects; Hertzian contact; continuously variable transmission; rolling resistance; speed pole; traction drive; multi-body system; efficient numerical procedure;

    Abstract : One category of mechanical systems that contains power-transferring point contacts is traction drive variators. These variators can be used in different concepts for Continuously Variable Transmissions (CVTs) and in vehicle applications, in order to achieve optimum engine operating conditions leading to improved driveability, reduced fuel consumption and an increase in overall vehicle performance.

  7. 5. Majorana Representation in Quantum Optics : SU(2) Interferometry and Uncertainty Relations

    Author : Saroosh Shabbir; Gunnar Björk; Maria Chekhova; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Majorana representation; Quantum optics; interferometry; SU 2 group; angular momentum; arbitrary optical gates; Fysik; Physics;

    Abstract : The algebra of SU(2) is ubiquitous in physics, applicable both to the atomic spin states and the polarisation states of light. The method developed by Majorana and Schwinger to represent pure, symmetric spin-states of arbitrary value as a product of spin-1/2 states is a powerful tool that allows for a great conceptual and practical simplification.
