Special Issue Information

Dear Colleagues,

Complex systems surround us at very different scales, from biomolecules and living cells to human socioeconomic systems and up to geophysical and ecological networks. Typically, they show dissipative structures induced by inherent nonlinear and non-equilibrium interactions and stabilized by the exchange of energy, matter, and information with their surroundings. These dynamical processes often involve some form of noise that, instead of representing an annoying disturbance, turns out to be a fundamental ingredient for the emergence of complex dynamics and an increase in the efficiency of the system behavior or in its performance toward achieving some task or to implement a desired protocol.

Many examples of such a beneficial role of noise can be found in physics and biology, where – among others – we may cite noise-assisted quantum phenomena, stochastic resonance, noise-enhanced stability, induced second-order-like phase transitions, enhanced diffusion in communication networks, noise-enhanced ordering, noise-assisted excitation transport in light-harvesting complexes for natural photosynthesis, information transfer in bistable and excitable systems and in quantum channels, and improved performance in neural activity, cognitive processes, or signal detection. However, also at the socioeconomic level have random strategies been demonstrated to be very successful in enhancing the efficiency of many systems in the context of game-theory, management of hierarchical organizations, political institutions, and financial markets.

For this Special Issue, we would like to collect examples of complex phenomena in different contexts and at any hierarchical level where noise or randomness can play a fundamental role in increasing the performance of the system.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
