  2. 21. Adult human neural stem cells : properties in vitro and as xenografts in the spinal cord

    Author : Ulf Westerlund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Action potential; adult; allodynia; auto-transplantation; endoscope; glutamate; hippocampus; human; neural stem cells; p75; patch clamp; progenitor; spinal cord injury; subventricular zone; synapse; transplantation;

    Abstract : Though the presence of stem cells in the adult human brain has been presented earlier, much has yet to be discovered about these cells. However, the mere potential of these cells has had a significant impact of how we today evaluate the regenerative capacity of the central nervous system and, importantly, on the possible means for science to provide insights in neural repair.

  4. 22. Accelerating column generation schemes : applications to routing problems

    Author : Andreas Westerlund; Oli Madsen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : Many integer optimization problems of great practical importance are today attacked with column generation. Merits of column generation is that it enables the use of compact and flexible formulations of many complex optimization problems, and that it often gives rise to good (strong) formulations.

  5. 23. Decomposition schemes for the traveling salesman subtour problem

    Author : Andreas Westerlund; Athanasios Migdalas; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Given an undirected graph with edge costs and both revenues and weights on the vertices, the Traveling Salesman Subtour Problem is to find a subtour that passes a depot vertex, satisfies a knapsack constraint on the vertex weights, and that minimizes edge costs minus vertex revenues along the subtour. This problem generalizes the Traveling Salesman Problem and is therefore -hard. READ MORE

  6. 24. Deciphering conformational ensembles and communication pathways in biomolecules

    Author : Annie M. Westerlund; Lucie Delemotte; Erik Lindahl; Kresten Lindorff-Larsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; Clustering; Machine learning; Network analysis; Calmodulin; KCNQ1; Biological Physics; Biologisk fysik;

    Abstract : Life is constructed by small building blocks called cells. Proteins are the biomolecules within these cells which carry out different functions. Proteins located in the cell membrane, for example, allow for the transport of ions and small molecules, as well as communication, across the cell membrane. READ MORE

  7. 25. The role of implementation science in healthcare improvement efforts : investigating three complex interventions

    Author : Anna Westerlund; Monica Nyström; Anneli Ivarsson; Rickard Garvare; Eva Eurenius; Johan Thor; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; healthcare improvement; knowledge-practice gap; implementation science; complex interventions; implementation strategy; change facilitation; case studies; folkhälsa; Public health; hälso- och sjukvårdsforskning; health services research;

    Abstract : For decades, scholars have found significant gaps between the knowledge available and the knowledge applied in healthcare. Many potential benefits of adequate knowledge based interventions are therefore never achieved. A considerable body of knowledge has evolved on how to promote a better uptake of evidence-based knowledge into routine use. READ MORE
