Hydrodynamics constrain choanoflagellate collar geometry
Tasawar Iqbal, Catherine Penington, Christian Thomas +1
As the closest living relatives of animals, choanoflagellates exhibit remarkable diversity. Even their microvilli collar, used to filter and capture food, varies significantly amon…
Remember when? Deciphering Ediacaran-Cambrian Metazoan behaviour and temporal memory using fossil movement paths
Brittany A. Laing, M. Gabriela Mángano, Luis A. Buatois +5
Evaluating the timing and trajectory of sensory system innovations is crucial for understanding the increase in phylogenetic, behavioural, and ecological diversity during the Ediac…
Spatial trends in Ediacaran Bilaterian trails
Brittany A. Laing, Luis A. Buatois, M. Gabriela Mángano +4
The Savannah Hypothesis and the Cambrian Information Revolution invoke the development of spatially heterogeneous resource distribution during the Ediacaran-Cambrian transition as…
Quantifying movement: Expanding the Ichnologist toolkit
Brittany A. Laing, Zoe Vestrum, Luke C. Strotz +4
The trace-fossil record serves as a rich dataset to examine fossil behaviour, ecologic interactions at community level, and evolutionary trends in behaviour across geological time.…
A Taylor swimming sheet under a finite Brinkman layer
Tasawar Iqbal, Catherine Penington, Christian Thomas +1
An asymptotic approach is employed to study the swimming speed of a two-dimensional Taylor swimming sheet beneath a Brinkman layer of finite thickness. This configuration is repres…
Slender Phoretic Loops and Knots
Panayiota Katsamba, Matthew D. Butler, Lyndon Koens +1
We present an asymptotic theory for solving the dynamics of slender autophoretic loops and knots. Our formulation is valid for non-intersecting 3D centrelines, with arbitrary chemi…
Viscous tubular-body theory for plane interfaces
Lyndon Koens, Benjamin J. Walker
Filaments are ubiquitous within the microscopic world. They occur frequently in both biological and industrial environments and display varied and rich dynamics. Their wide range o…
The slow viscous flow around doubly-periodic arrays of infinite slender cylinders
Lyndon Koens, Rohan Vernekar, Timm Krueger +2
The slow viscous flow through a doubly-periodic array of cylinders does not have an analytical solution. However, as a reduced model for the flow within fibrous porous media, this…
Tubular-body theory for viscous flows
Lyndon Koens
Cable-like bodies play a key role in many interdisciplinary systems but are hard to simulate. Asymptotic theories, called slender-body theories, are effective but apply in specific…
Jet-driven viscous locomotion of confined thermoresponsive microgels
Ivan Tanasijević, Oliver Jung, Lyndon Koens +2
We consider the dynamics of micro-sized, asymmetrically-coated thermoresponsive hydrogel ribbons (microgels) under periodic heating and cooling in the confined space between two pl…
Regularized Stokeslets lines suitable for slender bodies in viscous flow
Boan Zhao, Lyndon Koens
Slender-body approximations have been successfully used to explain many phenomena in low-Reynolds number fluid mechanics. These approximations typically use a line of singularity s…
Local drag of a slender rod parallel to a plane wall in a viscous fluid
Lyndon Koens, Thomas D. Montenegro-Johnson
The viscous drag on a slender rod by a wall is important to many biological and industrial systems. This drag critically depends on the separation between the rod and the wall and…
Geometric phase methods with Stokes theorem for a general viscous swimmer
Lyndon Koens, Eric Lauga
The geometric phase techniques for swimming in viscous flows express the net displacement of a swimmer as a path integral of a field in configuration space. This representation can…
Order and Information in the Patterns of Spinning Magnetic Micro-disks at the Air-water Interface
Wendong Wang, Gaurav Gardi, Paolo Malgaretti +9
The application of the Shannon entropy to study the relationship between information and structures has yielded insights into molecular and material systems. However, the difficult…
Method of regularised stokeslets: Flow analysis and improvement of convergence
Boan Zhao, Eric Lauga, Lyndon Koens
Since their development in 2001, regularised stokeslets have become a popular numerical tool for low-Reynolds number flows since the replacement of a point force by a smoothed blob…
A Light-Driven Microgel Rotor
Hang Zhang, Lyndon Koens, Eric Lauga +2
The current understanding of motility through body shape deformation of microorganisms and the knowledge of fluid flows at the microscale provides ample examples for mimicry and de…
The near and far of a pair of magnetic capillary disks
Lyndon Koens, Wendong Wang, Metin Sitti +1
Control on microscopic scales depends critically on our ability to manipulate interactions with different physical fields. The creation of micro-machines therefore requires us to u…
The swimming of a deforming helix
Lyndon Koens, Hang Zhang, Martin Moeller +2
Many microorganisms and artificial microswimmers use helical appendages in order to generate locomotion. Though often rotated so as to produce thrust, some species of bacteria such…
The boundary integral formulation of Stokes flows includes slender-body theory
Lyndon Koens, Eric Lauga
The incompressible Stokes equations can classically be recast in a boundary integral (BI) representation, which provides a general method to solve low-Reynolds number problems anal…
Analytical solutions to slender-ribbon theory
Lyndon Koens, Eric Lauga
The low-Reynolds number hydrodynamics of slender ribbons is accurately captured by slender-ribbon theory, an asymptotic solution to the Stokes equation which assumes that the three…
The non-Gaussian tops and tails of diffusing boomerangs
Lyndon Koens, Maciej Lisicki, Eric Lauga
Experiments involving the two-dimensional passive diffusion of colloidal boomerangs tracked off their centre of mobility have shown striking non-Gaussian tails in their probability…
Hydrodynamic interactions between nearby slender filaments
Yi Man, Lyndon Koens, Eric Lauga
Cellular biology abound with filaments interacting through fluids, from intracellular microtubules, to rotating flagella and beating cilia. While previous work has demonstrated the…
Microscale Flow Dynamics of Ribbons and Sheets
Thomas D. Montenegro-Johnson, Lyndon Koens, Eric Lauga
Numerical study of the hydrodynamics of thin sheets and ribbons presents difficulties associated with resolving multiple length scales. To circumvent these difficulties, asymptotic…
Rotation of slender swimmers in isotropic-drag media
Lyndon Koens, Eric Lauga
The drag anisotropy of slender filaments is a critical physical property allowing swimming in low-Reynolds number flows, and without it linear translation is impossible. Here we sh…
