A new test for random number generators: Schwinger-Dyson equations for the Ising model [PDF]
We use a set of Schwinger-Dyson equations for the Ising Model to check several random number generators. For the model in two and three dimensions, it is shown that the equations are sensitive tests of bias originated by the random numbers. The method is almost costless in computer time when added to any simulation.

The ascending central series of nilpotent Lie algebras with complex structure [PDF]
We obtain several restrictions on the terms of the ascending central series of a nilpotent Lie algebra $\mathfrak g$ under the presence of a complex structure $J$.

First-order transition in the one-dimensional three-state Potts model with long-range interactions [PDF]
The first-order phase transition in the three-state Potts model with long-range interactions decaying as $1/r^{1+\sigma}$ has been examined by numerical simulations using recently proposed Luijten-Bl\"ote algorithm. By applying scaling arguments to the interface free energy, the Binder's fourth-order cumulant, and the specific heat maximum, the change ...

Impact of monetary policy transmission mechanism in West African countries
The study analyzed the impact of monetary policy shocks on economic growth in 12 countries of the Economic Community of West African States (ECOWAS), using quarterly data from 1980(1) to 2017(4).

Self-Similar Exponential Approximants [PDF]
An approach is suggested defining effective sums of divergent series in the form of self-similar exponential approximants. The procedure of constructing these approximants from divergent series with arbitrary noninteger powers is developed. The basis of this construction is the self-similar approximation theory.

Resolving the space-time structure of sonoluminescence by intensity interferometry [PDF]
We analyze the spatial and temporal resolving power of two-photon intensity interferometry for the light emitting source in single bubble sonoluminescence (SBSL). We show that bubble sizes between several 10 nm and 3 um can be resolved by measuring the transverse correlation function, but that a direct determination of the flash duration via the ...

Darboux-integrable nonlinear Liouville-von Neumann equation [PDF]
A new form of a binary Darboux transformation is used to generate analytical solutions of a nonlinear Liouville-von Neumann equation. General theory is illustrated by explicit examples.

Wave function of a Brownian particle [PDF]
Using the Caldirola-Kanai Hamiltonian, we study the time evolution of the wave function of a particle whose classical motion is governed by the Langevin equation. We show, in particular, that if the initial wave function is Gaussian, then (i) it remains Gaussian for all times, (ii) its width grows, approaching a finite value when t->infinity, and (iii)
