Obtaining an accurate description of complex systems is challenging, particularly when their elements exhibit intricate interactions. We propose a data-driven multivariate Langevin equation (LE) to approximate real-world complex systems' ob...

A common approach to closing turbulent species flux in multicomponent Reynolds-averaged Navier-Stokes models is to use the standard gradient diffusion approximation. While such an approach has been shown to work well when applied to many ca...

Machine learning (ML) may be oblivious to human bias but it is not immune to its perpetuation. Marginalization and iniquitous group representation are often traceable in the very data used for training and may be reflected or even enhanced ...
Measuring the growth of Alfvén wave parametric decay instability using counter-propagating waves: Theory and simulations [0.03%]

The parametric decay instability (PDI) of Alfvén waves-where a pump Alfvén wave decays into a backward-propagating child Alfvén wave and a forward ion acoustic wave-is a fundamental nonlinear wave-wave interaction and holds significant i...

We report a quantitative study of the onset of dawn choruses of cicadas in several natural habitats. A time-frequency analysis of the acoustical signals is used to define an order parameter for the development of collective singing. The ens...

This article is the final part of a three-part series that develops a self-consistent theoretical framework describing the electromechanics of arbitrarily curved lipid membranes at the continuum scale. Owing to their small thickness, lipid ...

The displacement of a viscous fluid by another less-viscous fluid in porous media or Hele-Shaw cells produces a fingerlike interfacial pattern known as viscous fingering (VF). Classically, the dynamics of VF have been divided into two categ...

The endoplasmic reticulum (ER) is a network of sheetlike and tubular structures that spans much of a cell and contains molecules undergoing diffusive searches for targets, such as unfolded proteins searching for chaperones and recently fold...

Within the framework of continuum mechanics for materials with relaxation, this study investigates activity-induced laminar flow in an active nematic confined within an annular domain. Subsequent to the formulation of the problem as a nonli...

We use Langevin dynamics (LD) simulations to investigate single-file diffusion (SFD) in a dilute solution of flexible linear polymers inside a narrow tube with periodic boundary conditions (a torus). The transition from SFD, where the time ...
