Bacterial suspensions under flow
Fluids laden with motile bacteria enter in the category of active matter, a new field currently develo** at the convergence of biology,...
-
Microswimmers near surfaces
Both, in their natural environment and in a controlled experimental setup, microswimmers regularly interact with surfaces. These surfaces provide a...

Introduction
Lyotropic chromonic liquid crystals (LCLCs) are an emerging class of liquid crystals that have shown profound connections to biological systems in...
-
Equilibrium map**s in polar-isotropic confined active particles
Abstract.Despite their fundamentally nonequilibrium nature, the individual and collective behavior of active systems with polar propulsion and...

Magnetotactic bacteria
Magnetotactic bacteria are aquatic microorganisms with the ability to swim along the field lines of a magnetic field, which in their natural...

Category Theory and Quantum Mechanics
In the present chapter, we shall deal with the general logical–epistemological foundations of the quantum theory, where the stress is on...

NMR relaxation parameters of methyl groups as a tool to map the interfaces of helix–helix interactions in membrane proteins
In the case of soluble proteins, chemical shift map** is used to identify the intermolecular interfaces when the NOE-based calculations of spatial...

Lattice Boltzmann methods and active fluids
Abstract.We review the state of the art of active fluids with particular attention to hydrodynamic continuous models and to the use of Lattice...

Active Brownian particles moving in a random Lorentz gas
Abstract.Biological microswimmers often inhabit a porous or crowded environment such as soil. In order to understand how such a complex environment...

Formation and Properties of Membrane Protein/Amphipol Complexes
Complexes between membrane proteins (MPs) and amphipols (APols) can be obtained (i) by transferring to APols a detergent-solubilized MP, (ii) by...

Incompressible Homogeneous Anisotropic Turbulence: Pure Rotation
This chapter is devoted to purely rotating turbulence. An exhaustive review of physical and numerical experiments is provided, and the limits of...

Light-controlled flows in active fluids
Many photosynthetic microorganisms are able to detect light and move towards optimal intensities. This ability, known as phototaxis, plays a major...
-
Flagella, flexibility and flow: Physical processes in microbial ecology
How microorganisms interact with their environment and with their conspecifics depends strongly on their mechanical properties, on the hydrodynamic...

Two-dimensional motion of Brownian swimmers in linear flows
The motion of viruses and bacteria and even synthetic microswimmers can be affected by thermal fluctuations and by external flows. In this work, we...

Quantifying the sorting efficiency of self-propelled run-and-tumble swimmers by geometrical ratchets
Suitable asymmetric microstructures can be used to control the direction of motion in microorganism populations. This rectification process makes it...

Microorganism billiards in closed plane curves
Abstract.Recent experiments have shown that many species of microorganisms leave a solid surface at a fixed angle determined by steric interactions...

Non-Newtonian Aspects of Artificial Intelligence
The challenge of this work is to connect physics with the concept of intelligence. By intelligence we understand a capability to move from disorder...

Cell Crawling Driven by Spontaneous Actin Polymerization Waves
Cell motility is a signature of life. Crawling of eukaryotic cells on solid substrates is, for example, used to feed, to evade unfavorable...
