Fractional integral-like processing in retinal cones reduces noise and improves adaptation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-04)In the human retina, rod and cone cells detect incoming light with a molecule called rhodopsin. After rhodopsin molecules are activated (by photon impact), these molecules activate the rest of the signalling process for a brief period of time until they are deactivated by a multistage process. First, active rhodopsin is phosphorylated multiple times. Following this, they are further inhibited by the ... -

Estimating treatment prolongation for persistent infections
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-09)Treatment of infectious diseases is often long and requires patients to take drugs even after they have seemingly recovered. This is because of a phenomenon called persistence, which allows small fractions of the bacterial population to survive treatment despite being genetically susceptible. The surviving subpopulation is often below detection limit and therefore is empirically inaccessible but can ...
