Critical behavior in active lattice models of motility-induced phase separation

The European Physical Journal E : Soft matter, 2021
Lattice models allow for a computationally efficient investigation of motility-induced phase separation (MIPS) compared to off-lattice systems. Simulations are less demanding, and thus, bigger systems can be accessed with higher accuracy and better ...

Relative dispersion in fully developed turbulence: from Eulerian to Lagrangian statistics in synthetic flows [PDF]

, 1998
The effect of Eulerian intermittency on the Lagrangian statistics of relative dispersion in fully developed turbulence is investigated. A scaling range spanning many decades is achieved by generating a multi-affine synthetic velocity field with ...

Full Phase Diagram of Active Brownian Disks: From Melting to Motility-Induced Phase Separation. [PDF]

Physical Review Letters, 2018
We establish the complete phase diagram of self-propelled hard disks in two spatial dimensions from the analysis of the equation of state and the statistics of local order parameters.

Separation of spin and charge in paired spin-singlet quantum Hall states [PDF]

, 2002
We propose a series of paired spin-singlet quantum Hall states, which exhibit a separation of spin and charge degrees of freedom. The fundamental excitations over these states, which have filling fraction \nu=2/(2m+1) with m an odd integer, are spinons ...

Dual-Channel Cosine Function Based ITD Estimation for Robust Speech Separation

Sensors, 2017
In speech separation tasks, many separation methods have the limitation that the microphones are closely spaced, which means that these methods are unprevailing for phase wrap-around.

Turbulent energy cascade through equivalence of Euler and Lagrange motion descriptions and bifurcation rates [PDF]

Journal of Applied and Computational Mechanics, 2021
This work analyses the homogeneous isotropic turbulence by means of the equivalence between Euler and Lagrange representations of motion, adopting the bifurcation rates associated with Navier-Stokes and kinematic equations, and an appropriate hypothesis ...

A Survey on Nonconvex Regularization-Based Sparse and Low-Rank Recovery in Signal Processing, Statistics, and Machine Learning [PDF]

IEEE Access, 2018
In the past decade, sparse and low-rank recovery has drawn much attention in many areas such as signal/image processing, statistics, bioinformatics, and machine learning.

Global testing against sparse alternatives in time-frequency analysis [PDF]

, 2016
In this paper, an over-sampled periodogram higher criticism (OPHC) test is proposed for the global detection of sparse periodic effects in a complex-valued time series.

Statistical analysis of numerical solutions to constrained phase separation problems

Electronic Research Archive, 2023
We compute numerical solutions to a linearly constrained phase separation problem and a nonlinearly constrained phase separation problem on compact surfaces. Results are presented for oblate and prolate ellipsoids and Cassinian ovals.
