Collective effects in cellular structure formation mediated by compliant environments: a Monte Carlo study

open access: yes, 2006
Compliant environments can mediate interactions between mechanically active cells like fibroblasts. Starting with a phenomenological model for the behaviour of single cells, we use extensive Monte Carlo simulations to predict non-trivial structure ...

Core Precession and Global Modes in Granular Bulk Flow [PDF]

open access: yes, 2005
A transition from local to global shear zones is reported for granular flows in a modified Couette cell. The experimental geometry is a slowly rotating drum which has a stationary disc of radius R_s fixed at its bottom.

The regulatory network for the G1/S transition in Saccharomyces cerevisiae promotes the understanding of cancer developmental mechanisms

open access: yesBiotechnology & Biotechnological Equipment
The G1/S transition is crucial for regulating the initiation of cell division and is highly conserved across eukaryotes. This phase of the cell cycle involves intricate transcriptional controls that are essential for understanding cell proliferation ...

Nuclear Actin Polymerization Regulates Cell Epithelial‐Mesenchymal Transition

open access: yesAdvanced Science, 2023
Current studies on actin function primarily rely on cytoplasmic actin due to the absence of cellular models specifically expressing nuclear actin. Here, cell models capable of expressing varying levels of nuclear F/G‐actin are generated and a significant

Impurity spin textures across conventional and deconfined quantum critical points of two-dimensional antiferromagnets

open access: yes, 2007
We describe the spin distribution in the vicinity of a non-magnetic impurity in a two-dimensional antiferromagnet undergoing a transition from a magnetically ordered Neel state to a paramagnet with a spin gap.

Anisotropic strains, metal-insulator transition, and magnetoresistance of La$_{0.7}$Ca$_{0.3}$MnO$_{3}$ films

open access: yes, 2001
Thin films of perovskite manganite La$_{0.7}$Ca$_{0.3}$MnO$_{3}$ were grown epitaxially on various substrates by either the pulsed laser deposition method or laser molecular beam epitaxy.

CDK Phosphorylation of Translation Initiation Factors Couples Protein Translation with Cell-Cycle Transition

open access: yesCell Reports, 2018
Summary: Protein translation in eukaryotes is cell-cycle dependent, with translation rates more robust in G1 phase of the cell cycle than in mitosis. However, whether the fundamental cell-cycle control machinery directly activates protein translation ...

A geometrically controlled rigidity transition in a model for confluent 3D tissues

open access: yes, 2017
The origin of rigidity in disordered materials is an outstanding open problem in statistical physics. Previously, a class of 2D cellular models has been shown to undergo a rigidity transition controlled by a mechanical parameter that specifies cell ...

Structural behavior of uranium dioxide under pressure by LSDA+U calculations [PDF]

open access: yes, 2007
The structural behavior of UO2 under high pressure up to 300GPa has been studied by first-principles calculations with LSDA+U approximation. The results show that a pressure-induced structural transition to the cotunnite-type (orthorhombic Pnma) phase ...

The crosstalk between p38 and Akt signaling pathways orchestrates EMT by regulating SATB2 expression in NSCLC cells

open access: yesTumor Biology, 2017
Epithelial–mesenchymal transition is a crucial event for metastasis and could be mediated by several pathways such as phosphoinositide 3-kinase/Akt, mitogen-activated protein kinases, as well as many epigenetic regulators.
