Empirical evidence suggests that the size of the informal sector in the developing countries has increased considerably during the liberalized economic regime. The present paper purports to analyze the consequences of economic reforms on the wellbeing of the informal sector workforce using a three-sector general equilibrium model with two informal sectors. The theoretical analysis finds that di...

Based on the analysis of two dimensional dilaton gravity we argue that the semiclassical equations of black hole formation and evaporation should not be interpreted in terms of expectation values of operators in the exact quantum theory, but rather as WKB trajectories. Thus at the semiclassical level it does not seem possible to formulate a notion of quantum mechanical information loss. The dev...

We investigate theories in which gravity arises as an entropic force. We distinguish between two approaches to this idea: holographic gravity, in which Einstein’s equation arises from keeping entropy stationary in equilibrium under variations of the geometry and quantum state of a small region, and thermodynamic gravity, in which Einstein’s equation emerges as a local equation of state from con...

Examining the trade prospects for the new European Union (EU) member states and the EU associated partner countries is an important issue in the context of European eastward enlargement and greater economic integration with its immediate neighbours. An out-ofsample approach to projecting trade volumes for twenty countries of interest is adopted using a gravity equation for a panel data set of b...

Abstract We provide an updated study of some electronic properties graphene nanoscrolls, exploiting a related curved space Dirac equation for the charge carriers. To this end, we consider explicit parametrization in cylindrical coordinates, together with analytical solutions pseudoparticle modes living on two–dimensional background. These results are then used to obtain compact expression sampl...

Lie point symmetries of time-fractional potential Burgers' equation are presented. Using these symmetries fractional potential Burgers' equation has been transformed into an ordinary differential equation of fractional order corresponding to the Erdélyi-Kober fractional derivative. Further, an analytic solution is furnished by means of the invariant subspace method. AMS subject classifications:...

In 1930 Moore and Van Slyke (1) reviewed the various physical measurements, refractometric and others, that might serve as measures of the protein concentration of plasma, and concluded that specific gravity was the most reliable if application was required to pathological as well as normal plasmas. For plasma of nephritic patients they found that the relation between protein concentration and ...
