This research analyzes the dynamic properties of the difference equation that arises when markets exhibit serial correlation and mean reversion. We identify the correlation and reversion parameters for which prices will overshoot equilibrium (“cycles”) and/or diverge permanently from equilibrium. We then estimate the serial correlation and mean reversion coefficients from a large panel data set...

BACKGROUND AND PURPOSE Predicting response to rtPA is essential in the era of endovascular therapy for stroke. The purpose of this study was to elucidate prognostic factors of early neurologic improvement and long-term outcome with respect to the development and reversion of leptomeningeal collaterals in recanalization therapy after acute ischemic stroke. MATERIALS AND METHODS We analyzed con...

The mass reversion phenomenon in long term adapting yeasts was discovered by Spiegelman et al. (1950). The essential feature is that, whereas a galactose-grown population of cells of the gs genotype forms entirely positive colonies on galactose indicator plates, subculture of such a population on medium not containing galactose results in a sudden, mass change of the culture to a type that form...

This study compares and contrasts the multiple characterizations of mean reversion in financial time series as regards restrictions they imply. is accomplished by translating them into statements about an alternative measure, “Average Crossing Time” or ACT. We argue that ACT per se, provides not only a useful benchmark for degree reversion/aversion, but also intuitive, easily quantified sense o...

This work derives explicit series reversions for the solution of Calder\'on's problem. The governing elliptic partial differential equation is $\nabla\cdot(A\nabla u)=0$ in a bounded Lipschitz domain and with matrix-valued coefficient. corresponding forward map sends $A$ to projected version local Neumann-to-Dirichlet operator, allowing use boundary data finitely many measurements. It first sho...

The cultivation of perennial biomass crops (PBCs) on marginal lands is necessary to provide feedstock for the bio-based EU economy and accrue environmental benefits through carbon (C) sequestration in soil. Short rotation coppice (SRC) species, e.g., willow, black locust, poplar, rhizomatous grasses, miscanthus, switchgrass, giant reed, have been tested many projects last 10 years investigate t...
