In the most crucial foreign policy areas, Afghanistan and China, there may be long-term convergence between American and Indian interests, but at the moment, tactical differences lend the discussions an air of apprehension.
Hence, the Base scenario assumes a stable, favourable socio-economic situation in Europe and a long-term convergence of income levels in all European countries.
A data mining study found a surprisingly high number of hybrid NRPS-PKS gene clusters across three domains of life and this might be a consequence of long-term convergence between NRPS and PKS [ 38].
The pattern of swift, uninterrupted decline is now taken as the norm: the UN uses it to project a worldwide convergence towards the replacement rate of fertility (2.1, the rate at which a population stabilises in the long term).But convergence is not happening in Africa.
bThe parameter T represents agility of the algorithm and provides a tradeoff between long term performance (convergence to a global maximum) and short term performance (avoiding getting stuck at local maxima).
Over the long term, the convergence of visual and auditory signals reinforces an enduring spatial map in the IC.
Open image in new window Fig. 1 Daily evolution of the level (beta _0 ), slope (beta _1 ), curvature (beta _2 ) and the speed of convergence to long term rates (tau ) of the Nelson and Siegel model for the Spanish public debt market from January 2 , 1995to February 8 , 2010
The Nelson and Siegel (1987) model (NS hereafter) is an exponential component framework with four parameters by which the yield curve can be estimated parsimoniously; these parameters have the economic interpretation of level, slope, curvature and speed of convergence to long term rates.
The Nelson and Siegel (1987) (NS) model describes the yield curve through the four parameters (left{ {beta _0,beta _1,beta _2,tau } right} ) which represent the level (beta _0 ), the slope (-beta _1 ), the curvature (beta _2 ) and the speed of convergence to long term rates (tau ), together with the maturity, which is represented by (t).
