Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...

this paper examines critically the contributions of cournot, jevons and walras as the founders of classical mathematical economics from a methodological standpoint. advances in different economic schools and doctrines in the 19th century produced an environment of multi-dimensionality in economic analysis which was regarded by the pioneers of classical mathematical economists as a chaotic state...

We describe the master equation method for computing the kinetics of protein folding. We illustrate the method using a simple Go model. Presently most models of two-state fast-folding protein folding kinetics invoke the classical idea of a transition state to explain why there is a single exponential decay in time. However, if proteins fold via funnel-shaped energy landscapes, as predicted by m...

Transition-state theory (TST),’ as all chemists know, provides a marvelously simple and useful way to understand and estimate the rates of chemical reactions. The fundamental assumption2 of transition-state theory (Le., direct dynamics, no recrossing trajectories; see below), however, is based inherently on classical mechanics, so the theory must be quantized if it is to provide a quantitative ...

one of the basic subjects in political sociology of every society is the nature of stat in that society. the states have different economical social culture and political nature. the essay studies the political nature of the state in studies the political nature of the state in iran during pahlavi period , from the view point of transition to democracy. the aim of study the political nature of ...
