2. 1. NMR Studies of Inclusion Compounds

   Author : Sahar Nikkhou Aski; Jozef Kowalewski; Pierre Mutzenhardt; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; 13C spin relaxation; PFGNMR; Kinetics; Correlation time; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Abstract : This thesis presents the application of some of the NMR methods in studying host-guest complexes, mainly in solution. The general focus of the work is on investigating the reorientational dynamics of some small molecules that are bound inside cavities of larger moieties. READ MORE

4. 2. Precision Standard Model Phenomenology for High Energy Processes

   Author : Timea Vitos; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; precision phenomenology; Standard Model; NLO electroweak; decay coefficients; Drell-Yan process; top quark spin correlations; colour expansion; large-Nc limit; precision phenomenology; Standard Model; NLO electroweak; decay coefficients; Drell-Yan; top quark spin correlations; colour expansion; large-Nc truncation; Fysicumarkivet A:2023:Vitos;

   Abstract : The present status of particle physics is that the Standard Model has been completed with the discovery of theHiggs boson in 2012, but there is a multitude of phenomena in nature which is not accounted for by this model.Researchers are investigating possibilities for detecting new physics at the current particle physics facilities, withthe Large Hadron Collider (LHC) at the frontier.

5. 3. Fluorescence Studies of Membranes -- Proteins and Lipids, their Dynamics and Interactions

   Author : Johan Strömqvist; Jerker Widengren; Thorsten Wohland; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence correlation spectroscopy; cytokinesis; collision theory; protein-protein interactions; lipid dynamics; single-molecule experiment; Biological physics; Biologisk fysik;

   Abstract : In this thesis, fluorescence spectroscopy was utilized to probe protein and lipid dynamics and interactions in their native, or close to native, environments. Thereby insight could be gained into the fundamentals of bacterial cell division and the innateimmune system. A particular focus has been devoted to fluorescence fluctuations. READ MORE

6. 4. Neural Network Ensembles and Combinatorial Optimization with Applications in Medicine

   Author : Henrik Haraldsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; machine learning; artificial neural networks; ensemble methods; feature extraction; ECG; combinatorial optimization; mean field annealing; Computer science; numerical analysis; systems; Datalogi; control; system; kontroll; Artificial intelligens; Artificiell intelligens; Fysicumarkivet A:2003:Haraldsson;

   Abstract : Artificial neural network (ANN) and combinatorial optimization algorithms are developed, and applied to the medical domain. A novel method for training an ensemble of ANN is presented, based on random weight updates alternated with replication of networks with low error. READ MORE

7. 5. Simulations of thermoelectric transport in granularsuperconductors

   Author : Andreas Andersson; Jack Lidmar; Vladimir Krasnov; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Supraledning;

   Abstract : This thesis presents results from numerical simulations of the Nernst effect dueto phase fluctuations in models of two-dimensional granular superconductors. Inaddition other transport properties, such as thermal conductivity and electrical re-sistivity are calculated. READ MORE
