Thinning and thickening in active microrheology

open access: yes, 2014
When pulling a probe particle in a many-particle system with fixed velocity, the probe's effective friction, defined as average pulling force over its velocity, $\gamma_{eff}:=\langle F_{ex}\rangle/u$, first keeps constant (linear response), then ...

A pseudo active kinematic constraint for a biological living soft tissue: an effect of the collagen network [PDF]

open access: yes, 2008
Recent studies in mammalian hearts show that left ventricular wall thickening is an important mechanism for systolic ejection and that during contraction the cardiac muscle develops significant stresses in the muscular cross-fiber direction. We suggested

Pairwise frictional profile between particles determines discontinuous shear thickening transition in non-colloidal suspensions

open access: yesNature Communications, 2017
The process by which sheared suspensions go through a dramatic change in viscosity is known as discontinuous shear thickening. Although well-characterized on the macroscale, the microscopic mechanisms at play in this transition are still poorly ...

Tunable shear thickening in suspensions [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance When a concentrated suspension is strained, its viscosity can increase radically. This behavior, known as shear thickening, can be very useful to technological applications or highly problematic in industrial processes.

Assessment of relationship between maxillary sinus membrane thickening and the adjacent teeth health by cone-beam computed tomography

open access: yesJournal of Dental Sciences, 2021
Background/purpose: Maxillary posterior teeth have close anatomical proximity to the maxillary sinus floor. The aim of this retrospective study was to evaluate the associations between maxillary sinus membrane thickening and the adjacent teeth health by ...

Shear thickening in granular suspensions: inter-particle friction and dynamically correlated clusters

open access: yes, 2013
We consider the shear rheology of concentrated suspensions of non-Brownian frictional particles. The key result of our study is the emergence of a pronounced shear-thickening regime, where frictionless particles would normally undergo shear-thinning.

Can HRCT be used as a marker of airway remodelling in children with difficult asthma? [PDF]

open access: yes, 2006
BACKGROUND: Whole airway wall thickening on high resolution computed tomography (HRCT) is reported to parallel thickening of the bronchial epithelial reticular basement membrane (RBM) in adult asthmatics. A similar relationship in children with difficult

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Sheared active fluids: thickening, thinning and vanishing viscosity [PDF]

open access: yes, 2010
We analyze the behavior of a suspension of active polar particles under shear. In the absence of external forces, orientationally ordered active particles are known to exhibit a transition to a state of non-uniform polarization and spontaneous flow. Such
