The Effect of Micropatterned Pores on the Formation and Movement of Small Hepatocyte Colonies
Journal of Biomechanical Science and Engineering, 2008 Cell response on microporous membranes is important since the membranes are often used for the applications of tissue engineering. We previously developed the 3D stacked-up culture of hepatic progenitor cells, which are small hepatocytes (SHs), where the

Collective Synchronization of Undulatory Movement through Contact
Physical Review X, 2021 Many biological systems synchronize their movement through physical interactions. By far, the most well-studied examples concern physical interactions through a fluid: Beating cilia, swimming sperm and worms, and flapping wings all display ...

On following behaviour as a mechanism for collective movement [PDF]
Journal of Theoretical Biology, 2011 During collective movement, animals display a wide variety of mechanisms to maintain cohesion. In some species, individuals rely mainly on following their direct predecessor, thereby forming spectacular processions of individuals in single file. Despite being the simplest case of following behaviour, it is largely absent from the theoretical literature

Collective Movement with Signaling
, 2020 We consider a population of mobile agents able to make noisy observation of the environment and communicate their observation by production and comprehension of signals. Individuals try to align their movement direction with their neighbors. Besides, they try to collectively find and travel towards an environmental direction.

Sharp profiles in models of collective movements [PDF]
Nonlinear Differential Equations and Applications NoDEA, 2017 We consider a parabolic partial differential equation that can be understood as a simple model for crowds flows. Our main assumption is that the diffusivity and the source/sink term vanish at the same point; the nonhomogeneous term is different from zero at any other point and so the equation is not monostable.

Collective Discussion: Movement and Carceral Spatiality in the Pandemic
International Political Sociology, 2023 AbstractVarious measures of mobility restrictions were introduced since the outbreak of the COVID-19 pandemic. This collective discussion examines them in relation to six different carceral techniques that govern movement: citizenship, nativism, colonialism, infrastructure, gender, and borders.

On the mechanical interplay between intra- and inter-synchronization during collective cell migration : a numerical investigation [PDF]
, 2013 Collective cell migration is a fundamental process that takes place during several biological phenomena such as embryogenesis, immunity response, and tumorogenesis, but the mechanisms that regulate it are still unclear.

Collective Effects in Vortex Movements in Complex Plasmas [PDF]
Physical Review Letters, 2014 We study the onset and characteristics of vortices in complex (dusty) plasmas using two-dimensional simulations in a setup modeled after the PK-3 Plus laboratory. A small number of microparticles initially self-arranges in a monolayer around the void. As additional particles are introduced, an extended system of vortices develops due to a non-zero curl

A comparative analysis of online peace movement organizations [PDF]
, 2007 The use of the Internet for civic engagement by the general public is becoming increasingly prevalent, yet research in this area is still sparse. More studies are particularly needed in the area of cross-cultural comparisons of online social movements or
