Ergodic transition in a simple model of the continuous double auction. [PDF]
PLoS ONE, 2014 We study a phenomenological model for the continuous double auction, whose aggregate order process is equivalent to two independent M/M/1 queues. The continuous double auction defines a continuous-time random walk for trade prices.

Populismo e Autoritarismo – Uma breve reflexão teórica
Cadernos de Estudos Africanos, 2023 The 21st century is characterized by the re-emergence of populist solutions in various geographical areas of the world. This phenomenon does not adopt a single model but is based on a diversity of measures, rules, intensities, and ways of implementing ...

The Different Asymptotic Regimes of Nearly Unstable Autoregressive Processes [PDF]
, 2015 We extend classical results about the convergence of nearly unstable AR(p) processes to the infinite order case. To do so, we proceed as in recent works about Hawkes processes by using limit theorems for some well chosen geometric sums. We prove that when the coefficients sequence has a light tail, infinite order nearly unstable autoregressive ...

STABLE AND UNSTABLE REGIMES OF MASS ACCRETION ONTO RW AUR A [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present monitoring observations of the active T Tauri star RW Aur, from 2010 October to 2015 January, using optical high-resolution (R ≥ 10,000) spectroscopy with Canada–France–Hawaii Telescope/ESPaDOnS. Optical photometry in the literature shows bright, stable fluxes over most of this period, with lower fluxes (by 2–3 mag ...

Theory of chiral edge state lasing in a two-dimensional topological system
Physical Review Research, 2019 We theoretically study topological laser operation in a bosonic Harper-Hofstadter model featuring a saturable optical gain. Crucial consequences of the chirality of the lasing edge modes are highlighted, such as a sharp dependence of the lasing threshold

A Fluid Approach to Nonlinear Mode Coupling in a Dissipative Plasma [PDF]
Journal of Nuclear Research and Applications, 2023 The nonlinear dynamics of wave turbulence in a dissipative magnetized plasma system, comprised hot electrons and cold ions, are investigated using the hydrodynamical type of nonlinearity.

Inertial and stick-slip regimes of unstable adhesive tape peeling [PDF]
Soft Matter, 2016 We present an experimental characterization of the detachment front unstable dynamics observed during the peeling of pressure sensitive adhesives. We use an experimental set-up specifically designed to control the peeling angle θ and the peeled tape length L, while peeling an adhesive tape from a flat substrate at a constant driving velocity V.

A globally stable attractor that is locally unstable everywhere
AIP Advances, 2017 We construct two examples of invariant manifolds that despite being locally unstable at every point in the transverse direction are globally stable. Using numerical simulations we show that these invariant manifolds temporarily repel nearby trajectories ...
