The United States has employed three models of statebuilding over the last century, each animated by a different political theory. Statebuilding 1.0, developed and used from the late 1890s through the end of the Cold War, emphasized building loyal and politically stable subordinate states. Privileging American geopolitical and economic interests over those of local populations, the model was pr...

delivery of exogenous materials such as nucleic acids, peptides, proteins, and drugs into cells is an important strategy in modern cellular and molecular biology. recently, the development of gene carriers for efficient gene transfer into cells has attracted a great attention. furthermore, lack of effective drug delivery is one of the major problems of cancer chemotherapy. many physical methods...

Abstract We argue that Hamiltonian mechanics is more fundamental than Lagrangian mechanics. Our argument provides a non-metaphysical strategy for privileging one formulation of theory over another: ceteris paribus , general fundamental. illustrate this criterion through novel interpretation classical mechanics, based on three physical conditions. Two these conditions suffice recovering A third ...
