Image-based physical characterization of magnetotactic bacteria from an environmental sample
Mara Smite, Mihails Birjukovs, Mila Sirinelli-Kojadinovic +10
Magnetotactic bacteria (MTB) are a diverse group of microorganisms that are able to biomineralize magnetic nanoparticles. Most MTB remain uncultured, making population-level charac…
Explicit and fully automatic analysis of magnetotactic bacteria motion reveals the magnitude and length scaling of magnetic moments
Mara Smite, Mihails Birjukovs, Peteris Zvejnieks +3
Magnetotactic bacteria (MTB) are a diverse group of microorganisms whose movement can be directed via a magnetic field, which makes them attractive for applications in medicine and…
Physical model of serum supplemented medium flow in organ-on-a-chip systems
Viesturs Šints, Jānis Cīmurs, Mihails Birjukovs +8
Creating a physiologically relevant shear stress in organ-on-a-chip (OOC) devices requires careful tailoring of microfluidic flow parameters. It is currently fairly common to use a…
Magnetic control of magnetotactic bacteria swarms
Mihails Birjukovs, Klaas Bente, Damien Faivre +2
Magnetotactic bacteria (MTB) are of significant fundamental and practical interest, especially for applications such as drug delivery and general-purpose object manipulators and pa…
Optical imaging of MHD bubble flow in Hele-Shaw liquid metal cells
Aleksandrs Jegorovs, Mihails Birjukovs, Jevgenijs Telicko +1
As a simple and affordable alternative to often prohibitively expensive or unavailable X-ray and neutron imaging, an improved optical imaging method for bubble flow in Hele-Shaw li…
An image processing pipeline for in-situ dynamic X-ray imaging of directional solidification of metal alloys in thin cells
Mihails Birjukovs, Natalia Shevchenko, Sven Eckert
We present an image processing algorithm developed for quantitative analysis of directional solidification of metal alloys in thin cells using X-ray imaging. Our methodology allows…
