A DETERMINATION OF DARK MATTER BISPECTRUM WITH A LARGE SET OF N-BODY SIMULATIONS

open access: yes, 2009
We use a set of numerical N-body simulations to study the large-scale behavior of the reduced bispectrum of dark matter and compare the results with the second-order perturbation theory and the halo models for different halo mass functions.

Quantifying resolution in cosmological N-body simulations using self-similarity

open access: yes, 2021
International audienceWe demonstrate that testing for self-similarity in scale-free simulations provides an excellent tool to quantify the resolution at small scales of cosmological N-body simulations.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Numerical Determination of the Gravitational Cross Sections of an Accreting Binary

open access: yesThe Astrophysical Journal
A significant amount of work has been devoted to the study of small binary solar system objects. The majority of these binaries, especially among the near-Earth or main belt asteroids, have small radius ratios, implying a large difference in size between

Constraining cosmological parameters from N-body simulations with variational Bayesian neural networks

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Introduction: Methods based on deep learning have recently been applied to recover astrophysical parameters, thanks to the ability of these techniques to capture information from complex data.

Relativistic initial conditions for N-body simulations

open access: yes, 2017
Initial conditions for (Newtonian) cosmological N-body simulations are usually set by re-scaling the present-day power spectrum obtained from linear (relativistic) Boltzmann codes to the desired initial redshift of the simulation.

N-Body Simulations of Homogeneous Galaxies [PDF]

open access: yes, 2020
N-body simulations of homogeneous galaxies have been made to explore the physical proposal of critical density and mass, angular momentum and so on. Fundamental properties of galactic dynamics and structure formation have also been studied.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

open access: yesFEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

N-body models of open clusters

open access: yes, 2007
N-body simulations of open cluster evolution with primordial binaries are reviewed. In particular, recent results arising from models with initial N in the range of 20000100000 bodies are compared to earlier idealized models with N ~ 2000.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
