Morphodynamics of Active Nematic Fluid Surfaces
Sami C. Al-Izzi, Richard G. Morris
Morphodynamic equations governing the behaviour of active nematic fluids on deformable curved surfaces are constructed in the large deformation limit. Emphasis is placed on the for…
Bivalent Kinetics: Insights from Many Body Physics
Richard E. Spinney, Lawrence K. Lee, Richard G. Morris
Bivalency confers several concentration-dependent phenomena, including avidity, competitive exchange and multi-site competitive exchange. Since these concepts are crucial for a wid…
More ATP Does Not Equal More Contractility: Power And Remodelling In Reconstituted Actomyosin
Sami C. Al-Izzi, Sedigheh Ghanbarzadeh Nodehi, Darius V. Köster +1
The cytoskeletal component actomyosin is a canonical example of active matter since the powerstroke cycle locally converts chemical energy in the form of adenoside triphosphate (AT…
Active Flows and Deformable Surfaces in Development
Sami C. Al-Izzi, Richard G. Morris
We review progress in active hydrodynamic descriptions of flowing media on curved and deformable manifolds: the state-of-the-art in continuum descriptions of single-layers of epith…
Solvated Membrane Nanodiscoids: A Probe For The Effects Of Gaussian Curvature
R. G. Morris, T. R. Dafforn, M. S. Turner
Several methods now exist to solvate lipid bilayer discoids at the scale of tens of nanometres. Due to their size, such nanodiscoids have a comparatively large boundary-to-area rat…
Deriving mesoscopic models of collective behaviour for finite populations
Jitesh Jhawar, Richard G. Morris, Vishwesha Guttal
Animal groups exhibit emergent properties that are a consequence of local interactions. Linking individual-level behaviour to coarse-grained descriptions of animal groups has been…
Signatures of Mechanosensitive Gating
Richard G. Morris
The question of how mechanically-gated membrane channels open and close is notoriously difficult to address, especially if the protein structure is not available. This perspective…
Covariant Active Hydrodynamics of Shape-Changing Epithelial Monolayers
Richard G. Morris, Madan Rao
During the early-stages of embryo development, morphogenesis--- the emergence of shape and form in living organisms--- is almost exclusively associated with monolayers of tightly b…
Mobility Measurements Probe Conformational Changes in Membrane Proteins due to Tension
Richard G. Morris, Matthew S. Turner
The function of membrane-embedded proteins such as ion channels depends crucially on their conformation. We demonstrate how conformational changes in asymmetric membrane proteins m…
Growth-induced breaking and unbreaking of ergodicity in fully-connected spin systems
Richard G. Morris, Tim Rogers
Two canonical models of statistical mechanics, the fully-connected voter and Glauber-Ising models, are modified to incorporate growth via the addition or replication of spins. The…
Relaxation and curvature-induced molecular flows within multicomponent membranes
Richard G. Morris
The quantitative understanding of membranes is still rooted in work performed in the 1970s by Helfrich and others, concerning amphiphilic bilayers. However, most biological membran…
Interdependent networks: the fragility of control
Richard G. Morris, Marc Barthelemy
Recent work in the area of interdependent networks has focused on interactions between two systems of the same type. However, an important and ubiquitous class of systems are those…
Transport on coupled spatial networks
Richard G. Morris, Marc Barthelemy
Transport processes on spatial networks are representative of a broad class of real world systems which, rather than being independent, are typically interdependent. We propose a m…
Dynamical description of vesicle growth and shape change
Richard G. Morris, Duccio Fanelli, Alan J. McKane
We systematize and extend the description of vesicle growth and shape change using linear nonequilibrium thermodynamics. By restricting the study to shape changes from spheres to a…
Stability of growing vesicles
Richard G. Morris, Alan J. McKane
We investigate the stability of growing vesicles using the formalism of nonequilibrium thermodynamics. The vesicles are growing due to the accretion of lipids to the bilayer which…
