Will the Assad regime survive? It is a big moot point; it might be too late to restore peace or the status quo, but the government must take action as swiftly as possible to implement structural reforms in the country, allowing for more political participation, civil liberties, economic progress, social equality etc. Yet, this is not enough. Assad should also brace himself to compromise, to share
The historical role of European farming in southern and central Africa is a delicate matter that has received a great deal of attention among scholars over the years. Going through this vast literature a striking consensus emerges: success or failure of European farming in southern Africa was to a large extent depending on their access and control over labour. These propositions have so far never
An expression for the mean-square error (MSE) optimal Wigner cross-spectrum estimator is derived within a wide class of estimators. Using this expression and a simplemodel we are able to construct a new estimator which turns out to be superior compared to standard estimators such as Thomson multitapers and Welch method on simulated data.
Abstract : We present the first a priori derivation of a many-body theory for EXAFS with clearly defined approximations and with final expressions which are feasible for quantitative evaluations. We conclude that the conventional EXAFS expression should be complemented with a term that crudely is the main term, energy-shifted and scaled down by a factor of order 0.2-0.3. Further the f-factors depe
