  2. 1. Epigenetic regulation of gene expression in the vascular endothelium

    Author : Mia Magnusson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epigenetics; histone acetylation; DNA methylation; t-PA; PLAT; HUVECs; valproic acid; gene expression; enhancers;

    Abstract : Epigenetic mechanisms, such as DNA methylation and histone modifications, constitute one way for a cell or an organism to respond to changes in the surrounding environment. While histone modifications are recognized to be quite dynamic, DNA methylation has been considered a more stable, or long-term, modification. READ MORE

  4. 2. Simulations And Experiments Of Plasma-Induced Effects In Silicon Detectors

    Author : Ana Maria Gomez L; Ali Al-Adili; Diego Tarrío; Stephan Pomp; Andreas Solders; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VERDI - VElocity foR Direct particle Identification; PIPS - Passive Implanted Planar Silicon; PDT - Plasma Delay Time; PHD - Pulse Height Defect; FF - Fission Fragment; ToF - Time-of-flight; MCP - Micro Channel Plat; Kärnfysik; Nuclear Physics;

    Abstract : When an atomic nucleus undergoes fission, two fragments with different mass and kinetic energy are emitted. The highly unstable fission fragments (FFs) evaporate prompt neutrons soon after the nucleus splits. READ MORE

  5. 3. Trust-Based User Profiling

    Author : Nima Dokoohaki; Mihhail Matskin; Vlad Vlassov; Felix Wu; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; trust; userprofiling; userprofiles; privacy; interest; socialnetwork; recommendersystems;

    Abstract : We have introduced the notion of user profiling with trust, as a solution to theproblem of uncertainty and unmanageable exposure of personal data duringaccess, retrieval and consumption by web applications. Our solution sug-gests explicit modeling of trust and embedding trust metrics and mechanismswithin very fabric of user profiles. READ MORE

  6. 4. Multi-Modal Deep Learning with Sentinel-1 and Sentinel-2 Data for Urban Mapping and Change Detection

    Author : Sebastian Hafner; Yifang Ban; Paolo Gamba; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geoinformatics; Geoinformatik;

    Abstract : Driven by the rapid growth in population, urbanization is progressing at an unprecedented rate in many places around the world. Earth observation has become an invaluable tool to monitor urbanization on a global scale by either mapping the extent of cities or detecting newly constructed urban areas within and around cities.

  7. 5. The influence of soil pH on plant and microbial communities in sandy grasslands

    Author : Linda-Maria Mårtensson; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in situ 13CO2 labelling; disturbance; sandy grasslands; species diversity; acidification; soil pH; microbial biomass; C allocation;

    Abstract : Sandy, calcareous grasslands are species rich temperate semi-natural grasslands. The species composition in 136 plots was analysed in relation to soil chemistry parameters; extractable P and N, soil pH and lime content. READ MORE
