Universal level dynamics of complex systems

Universal dynamics on complex networks

We uncover a class of universal dynamics on weighted complex networks. In particular, we find that by incorporating a universal weighting scheme into real-world networks, the topological details of various real-world networks, whether biological, physical, technological, or social, have little influence on typical dynamical processes such as synchronization, epidemic spreading, and percolation....

Complex dynamics of nonlinear systems

Different nonlinear systems are presented exhibiting various dynamical phenomena, including bifurcations, chaotic dynamics, and synchronisation. Furthermore, methods for analysing, modelling and controlling complex dynamics are discussed. All these topics are illustrated with examples from work on nonlinear systems conducted at the DPI.

Assessment of research systems in universal health coverage-related organizations

    Background: Universal health coverage (UHC) is the desired goal of achieving universal access to health services without having to endure pain and financial difficulties. Multiple factors can help steer countries toward UHC. One of the most important factors is the production of valid quality evidence that can be achieved through research. The present study aimed at outlining...

Dynamics of cytochrome bf complex of photosynthesis apparatus

Photosynthesis is a process under which, the radiative energy is converted into the chemical one. Compared to the man-made devices, the photosynthesis apparatus is much more efficient. This high efficiency comes from its elaborate structure, very fast transition rates and a complex electron and proton transfer chain among the subunits of the apparatus. Its main subunits (Photosystem I (PSI), bf...
