A new theory is given for the decomposition of PFAS and the formation of BC8 Super-diamond with 13C isotope by application of RBL’s rotating magnetic field and static magnetic field for stimulating nuclei having nonzero nuclear magnetic moments (NMMs). The induced NMMs are proposed more readily in the 19F of PFAS due to large mass defect of 19F and the many C-F bonds per molecule. The super-diamond with 13C isotope is reasoned to form with its body center cubic lattice with central 13-carbon atom per cube due to the rotating magnetic field and resulting internal induced sp3 hybridization with more efficiency for the applied external pressure and internal pressure by 13C isotope to be better used to compress the resulting sp3 carbon atoms to BC8 super-diamond. The author invented the use of rotating electromagnetic and magnetic fields for affecting chemical dynamics in 2000.

Open-ended evolution (OEE) of interacting elementary cellular automata (ECA) was studied by Alyssa Adams et al. (2017). Some instances of composite ECA systems incorporating state-dependent dynamics were shown to satisfy definitions of unbounded evolution (UE) and innovation (INN), facilitating OEE. As an exercise in the rigorous analysis of systems not larger than sufficient to establish universal requirements for OEE, the scope of the study was restricted to small one-dimensional systems (ECAs) in which the perturbation of one subsystem by one other was one-way only (from "environment", e to "organism", o), but the authors recognized that their conclusions should also be relevant to the richer dynamics of large systems of mutually interacting subsystems. In this study, I explore the potential of three mutually interacting hodge podge machines for OEE and recognize that study of OEE in such comparatively large systems is provisionally tractable only by assessment of INN, considered as a reliable UE/OEE indicator.

Neural avalanches, characterized by cascading bursts of activity propagating across neural networks, are emerging as a fundamental phenomenon in brain function and development. This article explores the intricate relationship between neural avalanches and their role in optimizing neurodynamics, network formation, and information processing in the brain.Drawing from recent research findings, I delve into the criticality exhibited by neural avalanches, which put the brain at an optimal state for efficient information transmission and computational capabilities. The article examines how neural avalanches facilitate the formation of efficient neural networks through a process called "neuronal avalanche organizing" (NAO), where neurons participating in the same avalanches tend to wire together, leading to the emergence of functional neural circuits.Furthermore, I discuss the importance of moderate levels of D1 dopamine receptor activation in supporting avalanche dynamics. Appropriate D1 receptor activation helps maintain the balance between excitation and inhibition, regulating neural excitability and gain modulation, and contributing to synaptic plasticity mechanisms underlying network reorganization.Extending beyond neurodynamics and network formation, the article explores the pivotal role of neural avalanches in brain development. I try to elucidate how avalanche dynamics shape neural circuit formation, synaptic pruning, and refinement, as well as facilitate critical period plasticity and functional specialization of brain regions. Additionally, I highlight the contribution of neural avalanches to network integration and the emergence of higher cognitive functions and complex behaviors during development.By synthesizing current understanding and ongoing research, this article provides a comprehensive perspective on the intricate interplay between neural avalanches, neurodynamics, network formation, and brain development. It underscores the significance of this phenomenon in optimizing information processing, shaping neural architecture, and guiding the maturation of the brain's intricate circuitry.Word highlights: Neural avalanches, Criticality , Neurodynamics
