The Astrophysical JournalThere has been increasing evidence of shadows from scattered light observations of outer protoplanetary disks (PPDs) cast from the (unresolved) disk inner region, while in the meantime these disks present substructures of various kinds in the ...

Scalability of Hydrodynamic Simulations
, 2009 Many hydrodynamic processes can be studied in a way that is scalable over a vastly relevant physical parameter space. We systematically examine this scalability, which has so far only briefly discussed in astrophysical literature. We show how the scalability is limited by various constraints imposed by physical processes and initial conditions.

Hydrodynamic simulations of self-phoretic microswimmers [PDF]
Soft Matter, 2014 A mesoscopic hydrodynamic model to simulate synthetic self-propelled Janus particles which is thermophoretically or diffusiophoretically driven is here developed. We first propose a model for a passive colloidal sphere which reproduces the correct rotational dynamics together with strong phoretic effect.

Advanced Functional Materials, EarlyView.The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

The GHOSDT Simulations. II. Missing H2 in Simulations of a Self-regulated Interstellar Medium
The Astrophysical JournalObservations in the Galaxy and nearby spirals have established that the H i -to-H _2 transition at solar metallicity occurs at gas weight of P _DE / k _B ≈ 10 ^4 K cm ^−3 , similar to solar neighborhood conditions.

Numerical simulation of the dynamics of sedimentary river beds with a stochastic Exner equation
ESAIM: Proceedings and Surveys, 2015 At the scale of a river reach, the dynamics of the river bed is typically modelled by Exner equation (conservation of the solid mass) with an empirical solid flux of transported sediments, which is a simple deterministic algebraic ...

The Three Hundred project hydrodynamical simulations: Hydrodynamical weak-lensing cluster mass biases and richnesses using different hydro models [PDF]
Context. The mass of galaxy clusters estimated from weak-lensing observations is affected by projection effects, leading to a systematic underestimation compared to the true cluster mass. This bias varies with both mass and redshift.

Advanced Functional Materials, EarlyView.A pioneering magnetogenetic toolkit enables non‐invasive, precise spatiotemporal modulation of intracellular Wnt/β‐catenin signaling. Functionalized magnetic nanoparticles (MNPs@E/EC15) target cellular E‐cadherins to generate localized magnetomechanical forces under low‐intensity magnetic fields.

Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at z ≥ 10?
The Astrophysical Journal Letters, 2023 Recent photometric detections of extreme ( z > 10) redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation and in the most acute case, in tension with ΛCDM itself.
