2. 1. Functional and structural characterizations of phytoplankton-bacteria interactions in response to environmental challenges

   Author : Eva Sörenson; Catherine Legrand; Elin Lindehoff; Jarone Pinhassi; Sonya Dyhrman; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interactions; phytoplankton; microalgae; bacteria; communities; aquatic; diversity; functions; structure; species-specific; microbiome; core microbiome; response diversity; resilience; resource partitioning; competition; coexistence; amplicon sequencing; metatranscriptome; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

   Abstract : Microorganisms, such as phytoplankton and bacteria, make up ≈70% of aquatic biomass and contribute 50-85% of the oxygen in Earth’s atmosphere. The microbial loop concept and the discovery of the large diversity in microbial communities acknowledge that biotic interactions between microorganisms in addition to resource competition enable the recycling of energy and nutrients in aquatic food webs.

4. 2. Effects of Complement Opsonization of HIV on Dendritic Cells : and Implications for the Immune Response

   Author : Rada Ellegård; Marie Larsson; Jorma Hinkula; Johan D Söderholm; William Paxton; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; HIV; dendritic cells; complement; innate immune response; TLR signaling; T cell activation; NK cells; inflammation; antiviral response; immune evasion;

   Abstract : Dendritic cells are key players during HIV pathogenesis, and shape both the immediate immune response at the site of infection as well as directing the adaptive immune response against the virus. HIV has developed a plethora of immune evasion mechanisms that hijack dendritic cell functions, suppressing their ability to mount an accurate immune response and exploiting them for efficient viral transfer to target T cells.

5. 3. Learning flow functions : architectures, universal approximation and applications to spiking systems

   Author : Miguel Aguiar; Karl H. Johansson; João Sousa; Maarten Schoukens; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Learning flow functions of continuous-time control systems is considered in this thesis. The flow function is the operator mapping initial states and control inputs to the state trajectories, and the problem is to find a suitable neural network architecture to learn this infinite-dimensional operator from measurements of state trajectories.

6. 4. Derivation and application of response functions for nonlinear absorption and dichroisms

   Author : Tobias Fahleson; Patrick Norman; Daniel Crawford; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical spectroscopy; cubic response theory; damped response theory; magnetic circular dichroism; linear birefringence; two-photon absorption; TPA; resonant-inelastic x-ray scattering; RIXS; DALTON program; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

   Abstract : This thesis is titled ’Derivation and application of response functions for nonlinear absorption and dichroisms’ and was written by Tobias Fahleson at the Division of Theoretical Chemistry & Biology at KTH Royal Institute of Technology in Sweden. It explores and expands upon theoretical means of quantifying a number of nonlinear spectroscopies, including two-photon absorption, resonant inelastic x-ray scattering, Jones birefringence, and magnetic circular dichroism.
