  2. 1. Reinforcement in Biology : Stochastic models of group formation and network construction

    Author : Qi Ma; David Sumpter; Edward Codling; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reinforcement in biology; merge and split model; preferential attachment; reinforced random walk; network construction; shortest path problem; transport networks; ant algorithm; slime mould; physarum polycephalum; speed-accuracy tradeoff.; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Empirical studies show that similar patterns emerge from a large number of different biological systems. For example, the group size distributions of several fish species and house sparrows all follow power law distributions with an exponential truncation. READ MORE

  4. 2. Islet amyloid polypeptide (IAPP) : Mechanisms of Amyloidogenesis in the Pancreatic Islets and Potential Roles in Diabetes Mellitus

    Author : Zhi Ma; Arne Andersson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Islet amyloid is the most common characteristic feature of the islets in type 2 diabetes, being found in up to 90% of diabetic patients at post-mortem. lt has as its unique component the islet beta-cell peptide islet amyloid polypeptide (IAPP), which is eo-secreted with insulin.

  5. 3. Cancer Immunotherapy : Oncolytic viruses and CAR-T cells

    Author : Jing Ma; Di Yu; Magnus Essand; Mia Phillipson; Mohanraj Ramachandran; Karl-Johan Malmberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer immunotherapy; Oncolytic viruses; chimeric antigen receptor CAR -T cells; Helicobacter pylori Neutrophil Activating Protein;

    Abstract : Various forms of cancer immunotherapy have developed rapidly with improved survival and quality of life for cancer patients. Cancer immunotherapy aims to educate the patient’s immune system to eliminate cancer cells, including immune checkpoint inhibitors (ICIs), adoptive cell transfer (mostly T cells), oncolytic viruses (OVs) and cancer vaccines.

  6. 4. Studies of Morphology and Charge-Transfer in Bulk-Heterojunction Polymer Solar Cells

    Author : Zaifei Ma; Fengling Zhang; Olle Inganäs; Ludvig Edman; Linköpings universitet; []
    Keywords : ;

    Abstract : The work presented in this thesis focuses on the two critical issues of bulk-heterojunction polymer solar cells: morphology of active layers and energy loss during charge transfer process at electron donor/acceptor interfaces. Both issues determine the performance of polymer solar cells through governing exciton dissociation, charge carrier recombination and free charge carrier transport. READ MORE

  7. 5. Anti-Ageing Strategies : How to avoid failure in sodium-ion batteries

    Author : Le Anh Ma; Reza Younesi; Daniel Brandell; Laurent Duda; Philipp Adelhelm; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries; manganese-based cathodes; solid electrolyte interphase; ageing mechanism; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : In order to move away from fossil fuels, batteries are one of the most important technologies to store energy from renewable sources. The rapid demands of battery applications put pressure on supply chains of raw materials, such as lithium, nickel, copper, aluminium and cobalt. READ MORE
