  1. 16. Spatial and temporal ecology of oak-associated fungal communities

    Författare :Maria Faticov; Ayco Tack; Peter Hambäck; Paula Baptista; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; abiotic and biotic forces; climate warming; community ecology; foliar fungal community; host genotype; plant microbiome; powdery mildew; seasonal dynamics; warming-by-genotype interaction; Quercus robur; soil fungal community; spatial patterns; ekologi och evolution; Ecology and Evolution;

    Sammanfattning : Plants host a large diversity of microorganisms, which includes fungi, bacteria and archaea. Among these, fungi are highly diverse, and known to play a vital role in plant health and in regulation of the essential ecosystem functions. LÄS MER

  3. 17. Peakflow response of stream networks : implications of physical descriptions of streams and temporal change

    Författare :Anna Åkesson; Anders Wörman; Alberto Viglione; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streamflow routing; peakflow predictions; parameterization; hydrological response; stage-dependency; flooded cross-sections; stream networks; backwater effects; temporal change; land use change; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Through distributed stream network routing, it has quantitatively been shown that the relationship between flow travel time and discharge varies strongly nonlinearly with stream stage and with catchment-specific properties.Physically derived distributions of water travel times through a stream network were successfully used to parameterise the streamflow response function of a compartmental hydrological model.

  4. 18. Exploring patterns of empirical networks

    Författare :Luis E C Rocha; Petter Holme; Kimmo Kaski; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; complex systems; complex networks; network analysis; empirical networks; air transportation; consumer complaints; information technology; sexual contacts; epidemics; vaccination; Statistical physics; Statistisk fysik; Computational physics; Beräkningsfysik; Technology and social change; Teknik och social förändring; Epidemiology; Epidemiologi; Information technology; Informationsteknik; fysik; Physics; Statistics; statistik; Epidemiology; epidemiologi; Economics; nationalekonomi;

    Sammanfattning : We are constantly struggling to understand how nature works, trying to identify recurrent events and looking for analogies and relations between objects or individuals. Knowing patterns of behavior is powerful and fundamental for survival of any species. LÄS MER

  5. 19. Temporal representation of Motor Imagery : towards improved Brain-Computer Interface-based strokerehabilitation

    Författare :Jonatan Tidare; Elaine Åstrand; Pawel Herman; Mälardalens högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain-computer interface; eletroencephalogram; stroke rehabilitation;

    Sammanfattning : Practicing Motor Imagery (MI) with a Brain-Computer Interface (BCI) has shown promise in promoting motor recovery in stroke patients. A BCI records a person’s brain activity and provides feedback to the person in real time, which allows the person to practice his or her brain activity. LÄS MER

  7. 20. Diet and gut microbiota in cardiometabolic health: Studies from the Danish Diet, Cancer and Health – Next Generations Cohort and the sub-cohort MAX

    Författare :Agnetha Rostgaard-Hansen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiometabolic diseases; reproducibility; nutrients; gut microbiota; food frequency questionnaire; risk factors; 24-hour dietary recall; epidemiology; temporal variation; dietary patterns; cohort study; validity;

    Sammanfattning : Cardiometabolic diseases (CMD) are the leading cause of death globally. Diet is a key preventive factor of CMD and a determinant of gut microbiota. Gut microbiota, diet and their interactions have been associated with CMD. In observational studies, diet is measured by self-reported instruments, that need to be validated before use. LÄS MER
