A theoretical phase diagram for an active nematic on a spherical surface.

Soft matter

Brown AT.
PMID: 32391540
Soft Matter. 2020 May 21;16(19):4682-4691. doi: 10.1039/d0sm00166j.

Systems combining rod-shaped objects with self-generated motion such as suspensions of microtubules or growing bacterial colonies are commonly modeled as active nematics - nematic liquid crystals with an additional active stress term. Confining a 2D active nematic to the...

Hyperuniformity and density fluctuations at a rigidity transition in a model of biological tissues.

Soft matter

Zheng Y, Li YW, Ciamarra MP.
PMID: 32542303
Soft Matter. 2020 Jul 01;16(25):5942-5950. doi: 10.1039/d0sm00776e.

The suppression of density fluctuations at different length scales is the hallmark of hyperuniformity. Here, we explore the presence of this hidden order in a manybody interacting model of biological tissue, known to exhibit a transition, or sharp crossover,...

Measured Hyperelastic Properties of Cervical Tissue with Shear-Wave Elastography.

Sensors (Basel, Switzerland)

Ge W, Brooker G, Mogra R, Hyett J.
PMID: 35009856
Sensors (Basel). 2021 Dec 31;22(1). doi: 10.3390/s22010302.

The nonlinear mechanical behaviour of cervical tissue causes unpredictable changes in measured elastograms when pressure is applied. These uncontrolled variables prevent the reliable measurement of tissue elasticity in a clinical setting. Measuring the nonlinear properties of tissue is difficult...

Finite-element kalman filter with state constraint for dynamic soft tissue modelling.

Computers in biology and medicine

Xie H, Song J, Gao B, Zhong Y, Gu C, Choi KS.
PMID: 34182332
Comput Biol Med. 2021 Aug;135:104594. doi: 10.1016/j.compbiomed.2021.104594. Epub 2021 Jun 22.

This research work proposes a novel method for realistic and real-time modelling of deformable biological tissues by the combination of the traditional finite element method (FEM) with constrained Kalman filtering. This methodology transforms the problem of deformation modelling into...
