Realization of the Pascal based on Argon using a Fabry-Pérot refractometer
Isak Silander, Johan Zakrisson, Ove Axner +1
Based on a recent experimental determination of the static polarizability and a first-principles calculation of the frequency-dependent dipole polarizability of argon, this work pr…
Investigation of force approximations in tethered cells simulations
Johan Zakrisson, Krister Wiklund, Ove Axner +1
Simulations of tethered cells in viscous sub-layers are frequently performed using the Stokes drag force, but without taking into account contributions from surface corrections, li…
Cell shape identification using digital holographic microscopy
Johan Zakrisson, Staffan Schedin, Magnus Andersson
We present a cost-effective, simple and fast digital holographic microscopy method based upon Rayleigh-Sommerfeld back propagation for identification of the geometrical shape of a…
The biomechanical and structural properties of CS2 fimbriae
Narges Mortezaei, Bhupender Singh, Johan Zakrisson +2
Enterotoxigenic Escherichia coli (ETEC) are a major cause of diarrhea worldwide, and infection of children in underdeveloped countries often leads to high mortality rates. Isolated…
Damping properties of type 1 fimbriae
Johan Zakrisson, Krister Wiklund, Ove Axner +1
Type 1 fimbriae mediate adhesion of uropathogenic Escherichia coli (UPEC) to host cells. It has been hypothesized that fimbriae can, by their ability to uncoil under exposure to fo…
Damping effect of helix-like pili
Johan Zakrisson, Krister Wiklund, Ove Axner +1
Biopolymers are vital structures for many living organisms; for a variety of bacteria, adhesion polymers play a crucial role for the initiation of colonization. Some bacteria expre…
Multibody simulation of adhesion pili
Johan Zakrisson, Krister Wiklund, Martin Servin +3
We present a coarse grained rigid multibody model of a subunit assembled helix-like polymer, e.g., adhesion pili expressed by bacteria, that is capable of describing the polymers f…
