Collagen organisation in the fibrous joint capsules in the digits of the human hand

open access: yesJournal of Anatomy, EarlyView.
The function of the finger joints is important for daily life. In this review of the literature, we consider the role of collagen and its organization within the fibrous finger joint capsules of the interphalangeal (IP) joints and investigate the relationships between collagen orientation and joint function. Abstract Normal function of the hand and, in

Forman–Ricci communicability curvature of graphs and networks

open access: yesEuropean Journal of Applied Mathematics
Geometric parameters in general and curvature in particular play a fundamental role in our understanding of the structure and functioning of real-world networks. Here, the discretisation of the Ricci curvature proposed by Forman is adapted to capture the

Chronic and acute mediators of passive viscoelasticity in human skeletal muscle fibres

open access: yesExperimental Physiology, EarlyView.
Abstract The cellular viscoelastic modulus in skeletal muscle tissue responds dynamically to chronic stressors, such as age and exercise. Passive tissue mechanics can also be sensitive to acute stimuli, such as mechanical loading and/or activation‐induced muscle fatigue.

Geometric inequalities for manifolds with Ricci curvature in the Kato class [PDF]

open access: yes, 2016
We obtain an Euclidean volume growth results for complete Riemannian manifolds satisfying a Euclidean Sobolev inequality and a spectral type condition on the Ricci curvature.

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Ricci curvature of Bruhat orders

open access: yesAdvances in Applied Mathematics, 2022
We study the Ricci curvature of the Hasse diagrams of the Bruhat order of finite irreducible Coxeter groups. For this purpose we compute the maximum degree of these graphs for types $B_n$ and $D_n$. The proof uses a new graph $Γ(π)$ defined for any element $π$ in the corresponding group.

Expanding Ricci solitons with pinched Ricci curvature

open access: yesKodai Mathematical Journal, 2011
In this paper, we prove that expanding gradient Ricci solitons with (positively) pinched Ricci curvature are trivial ones. Namely, they are either compact or flat.

A phase transition modulates the protective function of a tardigrade disordered protein during desiccation

open access: yesProtein Science, Volume 34, Issue 10, October 2025.
Abstract Water is essential for active life, yet some organisms, such as tardigrades, can survive prolonged periods of drying‐induced dormancy. Cytoplasmic abundant heat‐soluble (CAHS) proteins are disordered proteins that undergo a phase transition from the solution to gel state.
