Structure formation in active networks [PDF]

open access: yesNature Materials, 2011
Structure formation and constant reorganization of the actin cytoskeleton are key requirements for the function of living cells. Here we show that a minimal reconstituted system consisting of actin filaments, crosslinking molecules and molecular-motor ...

Structure of structure formation theories [PDF]

open access: yesPhysical Review D, 1999
We study the general structure of models for structure formation, with applications to the reverse engineering of the model from observations. Through a careful accounting of the degrees of freedom in covariant gravitational instability theory, we show that the evolution of structure is completely specified by the stress history of the dark sector. The

Nonlinear Cosmological Structure Formation [PDF]

open access: yes, 1998
I present a general discussion of the evolution and model-dependence of both the linear and nonlinear power spectrum of density fluctuations. The features of the linear power spectrum in cosmological models with cold dark matter (CDM) and cold+hot dark ...

Cosmic structure formation [PDF]

open access: yesPhysica D: Nonlinear Phenomena, 1994
This article reviews the prevailing paradigm for how galaxies and larger structures formed in the universe: gravitational instability. Basic observational facts are summarized to motivate the standard cosmological framework underlying most detailed investigations of structure formation.

Biomechanical Characterization of Onion Epidermal Cell Walls

open access: yesBio-Protocol, 2017
Here we describe two experimental protocols to measure the biomechanical properties of primary (growing) plant cell walls, with a focus on analyzing cell wall epidermal strips of onion scales.

On the processes of segregation and stability of bimetallic nanoparticles Ni@Ag and Ag@Ni

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022
This work studied bimetallic nanoparticles Ni@Ag and Ag@Ni with the total number of atoms 4000 by the molecular dynamics method using the tight-binding potential. The pattern of segregation and structural formation is established and its characteristics

MEGA: merger graphs of structure formation [PDF]

open access: yes, 2020
When following the growth of structure in the Universe, we propose replacing merger trees with merger graphs, in which haloes can both merge and split into separate pieces.
