Lattice-gas model for collective biological motion [PDF]
Phys. Rev. E52, 5297 (1995), 1998 A simple self-driven lattice-gas model for collective biological motion is introduced. We find weakly first order phase transition from individual random walks to collective migration. A mean-field theory is presented to support the numerical results.

A DSGE Model of Slovakia with Frictional Labor Market and Monetary Regime Switch
Review of Economic Perspectives, 2017 The aim of this paper is to examine the dynamical and structural characteristics of Slovakia using a dynamic stochastic general equilibrium model augmented with search and matching mechanisms and other forms of frictions.

Muon Transverse Ionization Cooling: Stochastic Approach [PDF]
Phys.Rev.E52:1039-1042,1995, 1995 Transverse ionization cooling of muons is modeled as a Brownian motion of the muon beam as it traverses a Li or Be rod. A Langevin like equation is written for the free particle case (no external transverse magnetic field) and for the case of a harmonically bound beam in the presence of a focusing magnetic field. We demonstrate that the well known muon

Measuring monetary policy by money supply and interest rate: evidence from emerging economies
Review of Economic Perspectives, 2021 Although measuring monetary policy is a contentious issue in the literature, much less evidence on this issue is available for emerging economies. This paper aims to investigate the role of interest rate and money supply in measuring monetary policy in ...

Coin Tossing as a Billiard Problem [PDF]
Phys. Rev. E52, 3608, (1995)., 1995 We demonstrate that the free motion of any two-dimensional rigid body colliding elastically with two parallel, flat walls is equivalent to a billiard system. Using this equivalence, we analyze the integrable and chaotic properties of this new class of billiards. This provides a demonstration that coin tossing, the prototypical example of an independent

Monetary Transmission Channel, Oil Price Shock and the Manufacturing Sector in Nigeria
Folia Oeconomica Stetinensia, 2019 Research background: The need for diversification of the Nigerian economy has been emphasized and the manufacturing sector has a major role in this. Being an oil producing country, monetary policy is an important macroeconomic policy that has always been

Exact Solutions for Wave Propagation in Birefringent Optical Fibers [PDF]
Phys. Rev E52 3159 (1995), 1994 We carry out a group-theoretical study of the pair of nonlinear Schr\"{o}dinger equations describing the propagation of waves in nonlinear birefringent optical fibers. We exploit the symmetry algebra associated with these equations to provide examples of specific exact solutions.

Coupled Fluctuations near Critical Wetting [PDF]
Phys. Rev. E52 (1995), R5768, 1996 Recent work on the complete wetting transition has emphasized the role played by the coupling of fluctuations of the order parameter at the wall and at the depinning fluid interface. Extending this approach to the wetting transition itself we predict a novel crossover effect associated with the decoupling of fluctuations as the temperature is lowered ...
