Plant root growth against a mechanical obstacle: The early growth response of a maize root facing an axial resistance agrees with the Lockhart model
Manon Quiros, Marie-Béatrice Bogeat-Triboulot, Etienne Couturier +1
Plant root growth is dramatically reduced in compacted soils, affecting the growth of the whole plant. Through a model experiment coupling force and kinematics measurements, we pro…
Compression of a pressurized spherical shell by a spherical or flat probe
Etienne Couturier, Dominic Vella, Arezki Boudaoud
Measuring the mechanical properties of cells and tissues often involves indentation with a sphere, or compression between two plates. Previously, different theoretical approaches h…
Self-similar shapes under Errera division rule on the cone
Etienne Couturier
This study provides a general construction method of cell shape invariant by the Errera rule of division on a cone and provides analytical bounds for the apical angle of the cone o…
Construction of a universal ordinary differential equation of order 3
Etienne Couturier, Nicolas Jacquet
A universal ordinary differential equation of order 3 is constructed here. The equation is universal in the sense that any continuous function on a real segment can be…
Folded Goursat surface and banana-shaped seedpod
Etienne Couturier
Thin vegetal shells have recently been a significant source of inspiration for the de\text{sign} of smart materials and soft actuators. Herein is presented a novel analytical famil…
The filling law: a general framework for leaf shape diversity and its consequences on folded leaves
Etienne Couturier, Sylvain Courrech du Pont, Stéphane Douady
Leaves are packed in a bud in different ways, being flat, enrolled, or folded, but always filling the whole bud volume. This « filling law » has many consequences, in particular on…
