We demonstrate the existence of a frequency band exhibiting acoustic transparency in two- and three-dimensional dense granular suspensions, enabling the transmission of a low-frequency ballistic wave excited by a high-frequency broadband ul...

Impacted with sufficiently large stress, a dense, initially liquidlike suspension can be forced into a solidlike state through a process known as shear jamming. While the onset of shear jamming has been investigated extensively, much less i...
Interplay of order and disorder in two-dimensional critical systems with mixed boundary conditions [0.03%]

In spin systems such as the Ising model, the local order and disorder can be characterized by the order-parameter and energy density profiles 〈σ(r_{1})〉 and 〈ε(r_{2})〉, respectively. Does increasing the order at r_{1} always decrease ...
Scale-dependent breakdown of isotropic turbulence by off-axis rotation [0.03%]

An experimental investigation was conducted to explore the interplay of turbulence and noninertial effects introduced by off-axis rotation on isotropic-turbulence dynamics using tomographic particle image velocimetry. A cubic box, generatin...

We consider the dipolar spin ice on a 2D Apamea lattice whose geometry is derived from the square spin ice. We propose ground-state candidate configurations and show that not all vertices are in energetically favorable states. There is no m...
High-order moment closure for nonmagnetized electrons in partially ionized plasmas [0.03%]

Linearized moment equations are often used to derive closure models for the hydrodynamic equations of multicomponent plasmas near thermodynamic equilibrium. However, the linearized transport equations lose their validity in rarefied conditi...

We explore the potential of data assimilation (DA) within the multiscale framework of a shell model of turbulence, with a focus on the ensemble Kalman filter (EnKF). The central objective is to understand how measuring mesoscales (i.e., ine...

Machine learning, however popular and accessible, is computationally intensive and highly power-consuming, prompting interest in alternative physical implementations of learning tasks. We introduce a training scheme for physical systems tha...
Scale-free points-of-interest distribution in a city emerging from homogeneous Poissonian-point processes [0.03%]

Urban systems often exhibit scale-invariant properties, with power-law distributions observed in various spatial and temporal patterns of human behavior. A prominent example is the distribution of commercial activities and other points of i...
Intrinsic resonance depends on network size for coupled-delayed interacting oscillators [0.03%]

The collective frequency that emerges from synchronized neuronal populations-the network resonance-shows a systematic relationship with brain size: a whole-brain large network oscillates slowly, whereas finer parcellations of fixed volume e...
