This study investigates the throw of slender elastic projectiles. By integrating experimental data, numerical simulations, and theoretical analyses, we explore the acceleration and ejection dynamics of these projectiles. We considered vario...
Light-induced directed self-propulsion of active nanosized particles in a three-dimensional Brownian environment probed by heterodyne photon correlation laser spectroscopy [0.03%]

The motion of photocatalytic silver chloride nanoparticles (AgCl NPs) with radius R∼70nm that use electrolyte self-diffusiophoresis to achieve autonomous propulsion is fully characterized using heterodyne dynamic light scattering, allowing...
Cascading failures in networks of networks linked by directional and bidirectional hyperlinks [0.03%]

We study the cascading failures in systems of any number of networks connected to each other via groups of supply links, which we call hyperlinks. The individual supply links of a hyperlink connect individual nodes belonging to the pair of ...
Deviations from random-matrix entanglement statistics for kicked quantum chaotic spin-1/2 chains [0.03%]

It is commonly expected that for quantum chaotic many body systems, the statistical properties approach those of random matrices when increasing the system size. We demonstrate for various kicked spin-1/2 chain models that the average eigen...

We introduce a random matrix model for the stationary covariance of multivariate Ornstein-Uhlenbeck processes with heterogeneous temperatures, where the covariance is constrained by the Sylvester-Lyapunov equation. Using the replica method,...
Generic theory of interacting, spinning, active polar particles: A model for cell aggregates [0.03%]

We present a generic framework for describing interacting, spinning, active polar particles, aimed at modeling dense cell aggregates, where cells are treated as polar, rotating objects that interact mechanically with one another and their s...
Impact of pressure anisotropy on the cascade rate of Hall magnetohydrodynamic turbulence with biadiabatic ions [0.03%]

The impact of ion pressure anisotropy on the energy cascade rate of Hall-MHD turbulence with biadiabatic ions and isothermal electrons is evaluated in three-dimensional direct numerical simulations, using the exact (or third-order) law deri...

We consider a class of nonstandard, two-dimensional Hamiltonian models that may show features of active particle dynamics, and therefore, we refer to these models as active Hamiltonian (AH) systems. The idea is to consider a spin fluid wher...

We examine anew the relationship of directed polymers in random media on traditional hypercubic versus hierarchical lattices, with the goal of understanding the dimensionality dependence of the essential scaling index β at the heart of the...

Generative artificial intelligence methods are employed for the first time to construct a surrogate model for plasma turbulence that enables long-time transport simulations. The proposed GAIT (Generative Artificial Intelligence Turbulence) ...
