  2. 1. My first-passage : target search in physics and biology

    Author : Markus Nyberg; Ludvig Lizana; Martin Rosvall; Carlos Mejia-Monasterio; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; first-passage; mean first-passage time; mean first-arrival time; random walk; diffusion; zero-crossing; persistence; survival probability; network; resetting; teoretisk fysik; Theoretical Physics;

    Abstract : Random walks and diffusing particles have been a corner stone in modelling the random motion of a varying quantity with applications spanning over many research fields. And in most of the applications one can ask a question related to when something happened for the first time. That is, a first-passage problem. READ MORE

  4. 2. Early Life Environmental Risk Factors and Gut Microbiota in Juvenile Idiopathic Arthritis : - More than a gut feeling

    Author : Erik Kindgren; Rosaura Casas; Johnny Ludvigsson; Thomas Abrahamsson; Robin Kahn; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Juvenile idiopathic arthritis JIA ; Gut microbiota; Nutrition; Autoimmunity; Rheumatic disease;

    Abstract : Background: The autoimmune disease juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children, but the cause is not fully established. Only a small percentage (13–18%) of the risk of contracting the disease can be attributed to genetic factors, but environmental factors are believed to be behind most of the risk. READ MORE

  5. 3. Computational Studies of Cellulose-based Materials

    Author : Jiu Pang; Igor Zozoulenko; Alexandar Mehandzhiyski; Sergei Popov; Maria Sammalkorpi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Cellulose is a remarkable organic biopolymer and sustainable raw material existing in nature. Over the past several decades, the study of cellulose materials has attracted significant attention in chemistry, physics, biomedicine, and engineering fields. READ MORE

  6. 4. Epitaxy of oxide and nitride thin films grown by magnetron sputtering

    Author : Faezeh Alijan Farzad Lahiji; Per Eklund; Arnaud Le Febvrier; Biplab Paul; Tomas Nyberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The need for electronic devices with new functionalities has caused research to move in a way to design and utilize materials with high-performance thermoelectricity, widely used in batteries, sensors, and electronic devices. Two-dimensional materials (2D) with unique structures and remarkable properties have been identified to fabricate oxide heteroepitaxy. READ MORE

  7. 5. Nuclease Activity as a Biomarker in Cancer Detection

    Author : Alien Balian; Frank Hernandez; Kajsa Uvdal; Baris Ata Borsa; Ester Boix Borrás; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nucleases; Nuclease activity; Cancer detection; Diagnosis; Oligonucleotides; Nucleic acid probes; MRI-probes; Activatable probes;

    Abstract : Nucleases are a group of enzymes that cleave the phosphodiester bonds in nucleic acids. As such, nucleases act as biological scissors that exhibit a plethora of fundamental roles, in prokaryotes and eukaryotes, dependent or non-dependent on their catalytic capability. READ MORE
