A Previously Unnamed Amoeba, Mayorella clavella, nov. sp. [PDF]

open access: yes, 1951
During the last quarter of the nineteenth century, a considerable number of investigators gained fame for their studies of the organisms usually placed in the order Amoebida, class Rhizopodea, subphylum Sarcodina, phylum Protozoa (Jahn, 1949), commonly ...

Cell Sorting in an Active Nematic Vertex Model [PDF]

open access: yesarXiv
We study a mixture of extensile and contractile cells using a vertex model extended to include active nematic stresses. The two cell populations phase separate over time. While phase separation strengthens monotonically with an increasing magnitude of contractile activity, the dependence on extensile activity is non-monotonic, so that sufficiently high

Noise-induced transitions from contractile to extensile active stress in isotropic fluids [PDF]

open access: yesarXiv
Tissues of living cells are a prime example of active fluids. There is experimental evidence that tissues generate extensile active stress even though their constituting cells are contractile. Fluctuating forces that could result from cell-substrate interactions have been proposed to be able to induce a transition from contractile to extensile active ...

Reconstruction of the local contractility of the cardiac muscle from deficient apparent kinematics [PDF]

open access: yesarXiv
Active solids are a large class of materials, including both living soft tissues and artificial matter, that share the ability to undergo strain even in absence of external loads. While in engineered materials the actuation is typically designed a priori, in natural materials it is an unknown of the problem.
