N-body simulations for parametrized modified gravity [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We present MG-evolution, an N-body code simulating the cosmological structure formation for parametrized modifications of gravity. It is built from the combination of parametrized linear theory with a parametrization of the deeply non-linear cosmological regime extrapolated from modified spherical collapse computations that ...

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

N-body simulations of star forming regions [PDF]
, 2019 This thesis contains a body of work using N-body simulations and numerical methods to study star forming regions. It begins by introducing relevant topics, such as the basic picture of star formation, the en- vironment(s) that stars form in, stellar ...

N-Body Simulations and the Value of Ω [PDF]
Symposium - International Astronomical Union, 1978 We have recently completed a series of N-body simulations of galaxy clustering in an expanding universe (Aarseth, Gott and Turner 1977). the initial conditions and our results concerning galaxy clustering will be summarized by Sverre Aarseth at this meeting.

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Numerical Determination of the Gravitational Cross Sections of an Accreting Binary
The Astrophysical JournalA 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

Molecular 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.

MITF maintains genome stability in nonmelanocyte lineages
Molecular Oncology, EarlyView.MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

N-Body Simulations of Homogeneous Galaxies [PDF]
, 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.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer
Molecular Oncology, EarlyView.Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.
