Complex Systems Science and Its Applications in Blockchain, AI, Quantum ML and Big Data Forecasting

Dear Colleagues,

Many complex systems in all disciplines (e.g., physics, mathematics, engineering, information theory, nonlinear dynamics, anthropology, computer science, meteorology, sociology, economics, psychology, biology, medicine, etc.) possess nonlinear characteristics that vary over time and encompass hidden patterns. Intelligent decision-making approaches able to deal with continuously adjustable market environments are required in Blockchain, IoT and Decentralized FOG, Edge Cloud computing and Web3.0 applications. New developments at the intersection of Big Data Science, Quantum Computing, Blockchain approaches, Artificial Intelligence (AI), Machine learning (ML), Chaotic and Nonlinear dynamics, Bayesian methods, Evolutionary algorithms, have emerged to study Complex Systems in all scientific fields and topical areas.

The time-varying temporal parameters and variables of inherent nonlinearities in most complex systems remain unknown. Big Data statistics, Detrended Fluctuation analysis, Multi-resolution technique, Wavelets etc., provide new insights in analyzing and forecasting complex systems. Future Technologies with an integrated capacity to reveal nonlinear relationships, learn temporally variant parameter and variable spaces, in order to facilitate expert-level decisions. Blockchain technologies are gaining in importance. We are seeking new evidence to examine how the emergence of crypto-assets will create a new modus operandi for business among global economies, promote economic integration, yet also raise regulatory issues that all economies would have to address. Gamification could be incorporated into the mobile payment to encourage users, however there is a dark side of mobile payment which is explored in money laundering.

We will explore the growing interest of theories derived from information systems, to further add to the advancement of blockchain security systems, cyber-security, cryptography etc. Blockchains have advanced rapidly in recent years, from Bitcoin, the first decentralized cryptocurrency, to Ethereum, which includes smart contracts and the developing permissioned blockchain, e.g., Hyperledger fabric. Studies on the dynamical modeling, chaotic and nonlinear analyses, and control of these complicated systems are rare. Classical and Quantum (hybrid) Artificial intelligence and Machine learning promises to shake up traditional techniques applied to management and control of complex systems. Quantum computing integrated with Big Data and AI and ML-based methods provided higher reliability, accuracy ad predictability for complex systems as well as facilitate the detection of hidden knowledge patterns. We intend to explore recent advances in Future Technologies and their hybrid novel synergies in studying complex systems, as well as to offer possible future directions of research in this field. Contributions could incorporate control, stabilization, estimation, prediction, nowcasting, identification and simulation of all types of complex systems across scientific fields, utilizing Future Technologies in analyzing complex systems.
