  2. 11. 3D X-ray microscopy: image formation, tomography and instrumentation

    Author : Mårten Selin; Hans Hertz; Chris Jacobsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; image formation theory; partial coherence in imaging; wave propagation; tomography; instrumentation; Fysik; Physics;

    Abstract : Tomography in soft X-ray microscopy is an emerging technique for obtaining quantitative 3D structural information about cells. One of its strengths, compared with other techniques, is that it can image intact cells in their near-native state at a few 10 nm’s resolution, without staining. READ MORE

  4. 12. Vision Beyond the Fovea: Evaluation and Stimuli Properties

    Author : Abinaya Priya Venkataraman; Linda Lundström; Hema Radhakrishnan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peripheral vision; Visual optics; Optical correction; Orientation; Stimulus extent; Moving stimulus; Contrast sensitivity; Visual acuity; Central vision loss; Myopia; Biological Physics; Biologisk fysik;

    Abstract : This research is about evaluating vision in the periphery. Peripheral vision is of fundamental importance in the performance of our everyday activities. The aim of this thesis is to develop methods suitable for the evaluation of peripheral vision and to assess how different visual functions vary across the visual field. READ MORE

  5. 13. Molecular Dynamic Simulations of Biological Membranes

    Author : Qaiser Waheed; Olof Edholm; Friederike Schmid; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phospholipids; area compressibility; undulations; quantum corrections; cholesterol; phase transition; segregation;

    Abstract : Biological membranes mainly constituent lipid molecules along with some proteins and steroles. The properties of the pure lipid bilayers as well as in the presence of other constituents (in case of two or three component systems) are very important to be studied carefully to model these systems and compare them with the realistic systems.

  6. 14. Interactions and dynamics in biophysical model systems

    Author : Erik G. Brandt; Olle Edholm; Michael Odelius; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological physics; Biologisk fysik;

    Abstract : Computer simulations of simplified model systems provide understanding of how complex biological systems behave. The simulations give detailed information about the systems, with atomistic resolution, that can be used in combination with experimental knowledge to shed light on underlying physical principles.

  7. 15. Modeling Biophysical Mechanisms underlying Cellular Homeostasis

    Author : Padideh Kamali-Zare; Hjalmar Brismar; Charles Nicholson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological physics; Biologisk fysik;

    Abstract : Cellular homeostasis is the effort of all living cells to maintain their intracellular content when facing physiological change(s) in the extracellular environment. To date, cellular homeostasis is known to be regulated mainly by time-consuming active mechanisms and via multiple signaling pathways within the cells. READ MORE
