Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Electric controlling of surface metal-insulator transition in the doped BaTiO3 film

AIP Advances, 2017
Based on first-principles calculations, the BaTiO3(BTO) film with local La-doping is studied. For a selected concentration and position of doping, the surface metal-insulator transition occurs under the applied electric field, and the domain appears near

Biomagnetic Fluid Flow and Heat Transfer Study of Blood with Gold Nanoparticles over a Stretching Sheet in the Presence of Magnetic Dipole

Fluids, 2021
In this study, we examined the biomagnetic flow and heat transfer of an incompressible electrically conductive fluid (blood) containing gold nanoparticles over a stretching sheet in the presence of a magnetic dipole.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Identification of elastoplastic material parameters for the solid phase of metal foams

Materials & Design
For the prediction of the mechanical behavior of foams, the effective foam properties can be calculated from the mechanical properties of the solid phase and the geometric microstructure via computer simulation.

Mathematical Problems For A Dusty Gas Flow

Boletim da Sociedade Paranaense de Matemática, 2009
Summary: This brief review presents most important results of the authors dealing with mathematical models for the nonstationary two-phase flow of a dusty gas. We do not aim to analyze physical justifications and numerical simulations of dusty gas flows; our attention is focused on the qualitative properties of these models, such as local and global in

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

A new integrated numerical wave tank in OpenFOAM for hydrodynamic modelling of offshore renewables

Applied Ocean Research
This paper presents a new integrated hydrodynamic modelling framework for wave–structure interaction problems. It is developed by coupling a finite-volume-based fully nonlinear potential flow (FNPF) solver with the native OpenFOAM incompressible ...

Anodic titania nanotubes decorated with gold nanoparticles produced by laser-induced dewetting of thin metallic films

Scientific Reports, 2020
Herein, we combine titania layers with gold species in a laser-supported process and report a substantial change of properties of the resulting heterostructures depending on the major processing parameters.
