Almost all climate time series have some degree of nonstationarity due to external driving forces perturbing the observed system. Therefore, these external driving forces should be taken into account when constructing the climate dynamics. This paper presents a new technique of obtaining the driving forces of a time series from the slow feature analysis (SFA) approach, and then introduces them ...

in this study, irib regarding to the position and its functions of as a medium of communication has been analyzed and tried to identify the national and global key factors, in the next ten years to 1404, influencing it in political, social, economic and technological environment and then found out the organizational capabilities. therefore the future situation of a very large and very complex o...

researches in exploring of driving forces of regional endogenous development, concentrate on subjects which have been so controversial. regional endogenous development (red), together with other core regional development concepts, is usually focused on the sub-national regional development process of the home country. this paper attempts to conceptualize and examine regional endogenous developm...

The rate of erosion is the product of the concentration of active soil aggregates and their mean vertical velocity. The sediment concentration for a given time is proportional to the probability of detachment of first-time mobilized soil aggregates and to the probability of the deposited sediments’ redetachment. The probability of soil aggregate activation is equal to the probability of the dri...

In the modeling of solids the free energy, the energy, and the entropy play a central role. We show that the free entropy, which is defined as the negative of the free energy divided by the temperature, is similarly important. The derivatives of the free energy are suitable thermodynamical driving forces for reversible (i.e. Hamiltonian) parts of the dynamics, while for the dissipative parts th...

It is still unclear what molecular forces drive chaperone-mediated protein folding. Here, we obtain a detailed mechanistic understanding of the forces that dictate the four key steps of chaperone-client interaction: initial binding, complex stabilization, folding, and release. Contrary to the common belief that chaperones recognize unfolding intermediates by their hydrophobic nature, we discove...
