  5. 3. Stem cell fate regulation: computational modeling in the hematopoietic system

    Author : José Teles; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stochastic modeling; dynamical modeling; gene regulation; hematopoiesis; cell fate; stem cells; Fysicumarkivet A:2012:Teles;

    Abstract : The ability to sense the surrounding environment and respond to external fluctuations is a fundamental property of cells, the basic unit of life. Although cells can be very different in their composition and structure, they all have specialized molecular mechanisms that allow them to adapt to their environment, by coordinating gene expression and protein production.

  6. 4. Interaction of atomic ions with electrons : Recombination rate coefficients for C1+, F5+, Ne5+, S14+,S15+

    Author : Sultan Mahmood; Reinhold Schuch; Christoph Biedermann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : This thesis concentrates on electron-ion interaction studies, in particular focusing on dielectronic recombination (DR) of highly charged ions relevant to astrophysics and plasma physics. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time resolved photoluminescence; Physics; Fysik; Semiconductory physics; Halvledarfysik; Condensed matter:electronic structure; electrical; magnetic and optical properties; supraconductors; magnetic resonance; relaxation; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; egenskaper elektriska; magnetiska och optiska ; supraledare; spektroskopi; magnetisk resonans; microphotoluminescence; microcavities; photoluminescence; quantum optics; nano-optics; photonics; low dimensional structures; quantum dots; Fysicumarkivet A:2001:Zwiller;

    Abstract : The luminescence from single quantum dots has been studied. Single dot photoluminescence was studied under continuous as well as under pulsed excitation. Time-resolved studies revealed fast relaxations in quantum dots. The time resolved measurements were fitted with a set of rate equations. READ MORE
