Summary: The research describes a new model of self-organized criticality, called the e-pile model, which uses electrically charged particles to propagate activities and generate a critical state. Inspired by dielectric relaxation in random lattices, the model can be applied to various SOC processes with random injection and lattice-redistribution rules. It shows that the critical state involves self-evolving random percolation clusters, different from known self-organized versions, and presents a set of critical exponents based on random walks and complex conductivity formalism.

Summary: Power laws do not always indicate self-organized criticality, as they can also occur outside of critical points or for other reasons.

Summary: Self-organized criticality is a paradigm for understanding dynamical systems naturally driven to its critical point. It was realized that traffic flow might also fall into this category, suggesting that conventional traffic management strategies can become detrimental. This paper shows that the Kinematic Wave model and other related traffic models indeed exhibit self-organized criticality, thanks to the fractal nature of traffic and our desire to reach destinations as soon as possible.

Summary: We examine the probability distribution of avalanche sizes in self-organized critical systems. Our investigation reveals that while a power-law distribution is common, it may also decrease with increasing system size at a fixed avalanche size. We implement the scaling method and identify scaling functions to estimate the critical exponents and distinguish between exponents related to avalanche size and system size.

Summary: Information processing networks are shaped by local rewiring rules that promote links based on positively correlated node activities. A simple toy model is used to show that under these conditions, a core of densely connected nodes spontaneously forms. The appearance of this clustered state can be dynamically regulated by a fatigue mechanism to produce non-trivial avalanche exponents.

Summary: The study suggests that tropical precipitation clusters exhibit power-law frequency distributions due to the existence of island structures above convective thresholds on column-water-vapor topography. The agreement between precipitation clusters and CWV islands in frequency distributions and fractal dimensions supports this perspective.

Summary: The study reveals that synchronized neuronal groups exhibit a scale-invariant quadratic growth in the form of parabolic avalanches, which are primarily driven by critical neurons in the cortex. The diversity of these synchronized cell assemblies poses a challenge for brain theories.

Summary: Nanoparticle surfactants formed by interactions between nanoparticles and complementary polymers have been proposed as excellent stabilizers for liquid droplets in substance encapsulation and delivery applications. This study found that adding carboxylated nanoparticles to the dispersed phase and amino-terminated polymers to the continuous phases significantly reduces droplet size while increasing production rate. The combined effect of nanoparticles and polymers is greater than the sum of their individual effects due to the reduction of oil-water interfacial tension by nanoparticle surfactants.

Summary: No current model of consciousness is universally accepted, and a solid unifying framework is needed. Self-organized criticality (SOC) is considered a fundamental property of neural systems and a potential surrogate measure of consciousness. This study provides a comprehensive overview of research on SOC and its association with consciousness, highlighting the agreement between critical dynamics and influential theories in consciousness research.

Summary: Based on precipitation data from the rainy season in east China, it was found that the quiet time of precipitation follows a power-law distribution. This pattern holds for different threshold levels and regions. These results confirm that precipitation is an example of self-organized criticality in the weather system of China. By analyzing the exponent, mean quiet time, and hazard function of the probability density function, sensitive regions for precipitation events in China can be identified.

Summary: Formation of self-organized nanodiamond ring structures is reported due to dynamical heterogeneity in super undercooled carbon, created by nanosecond laser melting of amorphous carbon layers. Diamond tetrahedra self-organize to lead to the formation of string and ring structures, on which nanodiamonds nucleate and grow. Denser ring structures are formed in Q-carbon due to higher undercooling and enhanced diamond nucleation, showing larger average size and higher growth velocities compared to homogeneous nucleation.

Summary: This study experimentally investigated various interrelated multi-scale processes that occur on the frictional surface during cutting, presenting the repetitive formation and breakage of buildups and periodic changes in thermal barrier tribo-films. These cyclic phenomena ultimately lead to the catastrophic failure of the entire tribo-system.

Summary: The transcriptomic data analysis in this study revealed one syngamy-associated and 16 meiosis-associated proteins in P. cordatum. Additionally, an amino acid sequence homologous to bacterial MutS2 protein was detected for the first time, leading to discussions on the presence and origin of MutS2 in dinoflagellates.

Summary: This study investigates the role of zinc ions in Mycobacterium marinum infection, revealing that the bacterium can sense toxic levels of zinc ions and respond by upregulating a specific isoform of a zinc efflux transporter. The interplay of zinc ion transporters ZntA and ZntB affects bacterial growth, with deletion of these transporters leading to different levels of zinc accumulation in Mycobacterium-containing vacuoles. Overall, zinc poisoning plays a crucial role in restricting mycobacterial infections by impacting zinc ion homeostasis.
