Mass Exchange Processes with Input [PDF]
J. Phys. A 48, 205003 (2015), 2015 We investigate a system of interacting clusters evolving through mass exchange and supplemented by input of small clusters. Three possibilities depending on the rate of exchange generically occur when input is homogeneous: continuous growth, gelation, and instantaneous gelation. We mostly study the growth regime using scaling methods.

Kinetic Model of Mass Exchange with Dynamic Arrhenius Transition Rates [PDF]
Physica A, 444, pp. 95-109, 2016, 2014 We study a nonlinear kinetic model of mass exchange between interacting grains. The transition rates follow the Arrhenius equation with an activation energy that depends on the grain mass. We show that the activation parameter can be absorbed in the initial conditions for the grain masses, and that the total mass is conserved.

Noise Trading and Exchange Rate Regimes [PDF]
SSRN Electronic Journal, 2002 Both the literature and new empirical evidence show that exchange rate regimes differ primarily by the noisiness of the exchange rate, not be measurable macroeconomic fundamentals. This motivates a theoretical analysis of exchange rate regimes with noise traders.

Spin relaxation in quantum dots due to electron exchange with leads [PDF]
Phys. Rev. Lett. 101, 226805 (2008), 2008 We calculate spin relaxation rates in lateral quantum dot systems due to electron exchange between dots and leads. Using rate equations, we develop a theoretical description of the experimentally observed electric current in the spin blockade regime of double quantum dots. Single expression fits the entire current profile and describes the structure of

Detection of Structural Regimes and Analyzing the Impact of Crude Oil Market on Canadian Stock Market: Markov Regime-Switching Approach [PDF]
arXiv, 2021 This study aims to analyze the impact of the crude oil market on the Toronto Stock Exchange Index (TSX)c based on monthly data from 1970 to 2021 using Markov-switching vector autoregressive (MSI-VAR) model. The results indicate that TSX return contains two regimes, including: positive return (regime 1), when growth rate of stock index is positive; and ...

Exchange Rate Regimes and the Real Exchange Rate [PDF]
Journal of Economic Integration, 1995 It is well established now that the (nominal) exchange rate regime has important implications for the behavior of real exchange rates. Two key stylized facts in this regard are that real exchange rate variability is greater under flexible exchange rates than under fixed exchange rates and that real and nominal exchange rate movements are positively ...

Phys. Rev. E 68, 031104 (2003), 2003 We study a class of growth processes in which clusters evolve via exchange of particles. We show that depending on the rate of exchange there are three possibilities: I) Growth: Clusters grow indefinitely; II) Gelation: All mass is transformed into an infinite gel in a finite time; and III) Instant Gelation.

CAPITAL ACCOUNT LIBERALIZATION AND EXCHANGE RATE REGIME CHOICE, WHAT SCOPE FOR FLEXIBILITY IN TUNISIA? [PDF]
, 2006 Capital account liberalization and exchange rate regime choice, what scope for flexibility in Tunisia? This study evaluates within a game-theoretic framework the exchange rate regime from a welfare perspective.

The Macroeconomic Implication of Exchange Rate Regimes [PDF]
SSRN Electronic Journal, 2011 This study investigates the relation between macroeconomic variables such as real GDP growth, inflation, unemployment rate, trade deficit and the exchange regimes. The idea is to explore whether the macroeconomic indicators give better result when are under the influence of fixed or fluctuating exchange rates.

Interatomic collisions in a tightly confined Bose gas [PDF]
Phys. Rev. A 64, 012706 (2001), 2000 We discuss pair interatomic collisions in a Bose gas tightly confined in one (axial) direction and identify two regimes of scattering. In the quasi2D regime, where the confinement frequency $\omega_0$ greatly exceeds the gas temperature $T$, the scattering rates exhibit 2D features of the particle motion.
