  2. 16. Structure and chemical ordering in metallic nanoparticles from atomic scale modeling

    Author : Magnus Rahm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; regular truncated octahedron; chemical ordering; nanoparticle shapes; molecular dynamics; icosahedron; Monte Carlo; modeling; Marks decahedron; nanoparticle structures;

    Abstract : In the last decades, a wide range of attractive properties have put metallic nanoparticles in the spotlight. These properties, often related to optical response and catalytic performance, are to a large extent dependent on structure and chemical ordering, that is, the distribution of elements in the nanoparticle.

  4. 17. Thioredoxin system in normal and transformed human cells

    Author : Bita Sahaf; Anders Rosén; L. A. Herzenberg; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: Thioredoxin (Trx) and thioredoxin reductase (TrxR), together with NADPH, constitute the Trx system, a major antioxidant entity that helps maintain a reducing environment within living cells. Trx designates a family of proteins that are related on the basis of structure and function. READ MORE

  5. 18. On Model Simplification in System Identification

    Author : Bo Wahlberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model simplification; System identification;

    Abstract : This report deals with the connection between system identification and model reduction. We propose an identification algorithm that is based on the least squares identification method and either of the model reduction techniques: Frequency weighted truncated balanced realization or frequency weighted optimal Hankel-norm model reduction.

  6. 19. Numerical solution of the Fokker–Planck approximation of the chemical master equation

    Author : Paul Sjöberg; Per Lötstedt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Abstract : The chemical master equation (CME) describes the probability for the discrete molecular copy numbers that define the state of a chemical system. Each molecular species in the chemical model adds a dimension to the state space. READ MORE

  7. 20. DNA-dependent protein kinase in human cells

    Author : Annahita Sallmyr; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzymology; virology; mycology; mykologi; virologi; Proteiner; enzymologi; bacteriology; Microbiology; Sjögren s syndrome; HL60; PMN; Ku86v; Ku86; DNA-PK; DNA DSBs; NHEJ; Proteins; Mikrobiologi; bakteriologi;

    Abstract : DNA-dependent protein kinase (DNA-PK) is a holoenzyme consisting of a regulatory subunit, the heterodimeric Ku70/86, and a catalytic subunit known as DNA-dependent protein kinase catalytic subunit (DNA-PKcs). DNA-PK takes part in a number of cellular functions including growth control, immunoglobulin gene rearrangement and DNA repair. READ MORE
