Bioinspired Mechanisms and Actuation of Soft Robotic Crawlers. [PDF]
Adv Sci (Weinh)Researchers have been developing soft materials and robotic crawlers inspired by soft‐bodied animals to mimic effective crawling in complex environments. This review explores the state‐of‐the‐art in soft crawlers, highlighting the interaction between materials, crawling mechanisms, actuation, and applications. The review concludes by providing insights

Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Impact of small‐scale gravity waves on tracer transport
Quarterly Journal of the Royal Meteorological Society, EarlyView.We extend a gravity wave (GW) parametrization to calculate the tracer transport due to the GW–Stokes drift and next‐order effects, where the approach is validated by comparing coarse‐resolution simulations with parametrized GWs to high‐resolution, wave‐resolving reference simulations.

Hydrodynamic instabilities in miscible fluids
, 2017 Hydrodynamic instabilities in miscible fluids are ubiquitous, from natural phenomena up to geological scales, to industrial and technological applications, where they represent the only way to control and promote mixing at low Reynolds numbers, well ...

Global weak solutions for the compressible Poisson–Nernst–Planck–Navier–Stokes system
Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.Abstract We consider the compressible Poisson–Nernst–Planck–Navier–Stokes (PNPNS) system of equations, governing the transport of charged particles under the influence of the self‐consistent electrostatic potential, in a three‐dimensional bounded domain.

A unitary quantum lattice gas algorithm for two dimensional quantum turbulence [PDF]
, 2011 Quantum vortex structures and energy cascades are examined for two dimensional quantum turbulence (2D QT) at zero temperature. A special unitary evolution algorithm, the quantum lattice gas (QLG) algorithm, is employed to simulate the Bose-Einstein ...

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.Abstract Monthly mean reanalysis from assimilating global ocean circulation models spanning 27 years is used to study subsurface secondary acoustic ducts, which provide waveguides for the transmission of mid‐frequency sound. A systematic diagnosis of secondary ducts from monthly mean temperature and salinity fields characterizes their distribution and ...

Singular diffusionless limits of double-diffusive instabilities in magnetohydrodynamics [PDF]
, 2017 We study local instabilities of a differentially rotating viscous flow of electrically conducting incompressible fluid subject to an external azimuthal magnetic field. In the presence of the magnetic field the hydrodynamically stable flow can demonstrate
