2. 11. Supersymmetry vis-à-vis Observation : Dark Matter Constraints, Global Fits and Statistical Issues

   Author : Yashar Akrami; Joakim Edsjö; Lars Bergström; Roberto Trotta; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; cosmology of theories beyond the Standard Model; dark matter; gamma rays; dwarf galaxies; direct detection; statistical techniques; scanning algorithms; genetic algorithms; statistical coverage; Astroparticle physics; Astropartikelfysik; Cosmology; Kosmologi; Astroparticle physics; Astropartikelfysik; teoretisk fysik; Theoretical Physics;

   Abstract : Weak-scale supersymmetry is one of the most favoured theories beyond the Standard Model of particle physics that elegantly solves various theoretical and observational problems in both particle physics and cosmology. In this thesis, I describe the theoretical foundations of supersymmetry, issues that it can address and concrete supersymmetric models that are widely used in phenomenological studies. READ MORE

4. 12. Cosmological aspects of universal extra dimensions

   Author : Torsten Bringmann; Lars Bergström; Pierre Binetruy; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cosmology; dark matter; extra dimensions; Cosmology; Kosmologi;

   Abstract : It is an intriguing possibility that our world may consist of more than three spatial dimensions, compactified on such a small scale that they so far have escaped detection. In this thesis, a particular realization of this idea -- the scenario of so-called 'universal extra dimensions' (UED) -- is studied in some detail, with a focus on cosmological consequences and appplications.

5. 13. Healthcare context for knowledge translation in Vietnam : Development and application of the Context Assessment for Community Health (COACH) tool

   Author : Duong Duc; Lars Wallin; Anna Bergström; Leif Eriksson; Bui Ha; Christopher R Burton; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Knowledge translation; Vietnam; Low- and middle-income country; Healthcare context; Context Assessment for Community Health COACH tool; Psychometric properties; Tool development.; Hälso- och sjukvårdsforskning; Health Care Research;

   Abstract : The failure to translate evidence into clinical practice has been repeatedly highlighted. This failure is partly attributed to disregarding the context within which healthcare is delivered. READ MORE

6. 14. The Dark Side of the Universe

   Author : Martin Eriksson; Lars Bergström; Pierre Salati; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astroparticle physics; Physics; Fysik;

   Abstract : The dark side of the Universe presents astroparticle physics with its most outstanding challenge to date. As observational cosmology in recent years has reached a level of unprecedented accuracy, we have learned that there is very little in the Universe that we know much about, and very much about which we know very little.

7. 15. Studies of α-synuclein Oligomers-with Relevance to Lewy Body Disorders

   Author : Therese Fagerqvist; Martin Ingelsson; Joakim Bergström; Lars Lannfelt; Michael G Schlossmacher; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha-synuclein; Parkinson´s disease; Lewy body dementia; Oligomer; Monoclonal antibody; Immunotherapy; Reactive aldehydes; Medical Science; Medicinsk vetenskap;

   Abstract : The protein alpha-synuclein (α-synuclein) accumulates in the brain in disorders such as Parkinson’s disease (PD) and dementia with Lewy bodies (DLB). It is believed that the monomeric form of α-synuclein can adopt a partially folded structure and start to aggregate and form intermediately sized oligomers or protofibrils. READ MORE
