Global Regulatory Systems

780
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

4.1K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Kirchoff's Rules: Application

2.1K
Kirchhoff's rules quantify the current flowing through a circuit and the voltage variations around the loop in a circuit. Applying Kirchhoff's rules generates a set of linear equations that allow us to find the unknown values in circuits. These may be currents, voltages, or resistances.
When applying Kirchhoff's first rule, the junction rule, label the current in each branch and decide its direction. If the chosen direction is wrong, it will have the correct magnitude, although the...

Sequence Networks of Rotating Machines

508
A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Summary
This summary is machine-generated.

This study introduces self-organized temporal criticality (SOTC), a new model inspired by evolutionary game theory. It demonstrates how individual selfish choices can lead to spontaneous cooperation in social systems, differing from traditional Self-Organized Criticality (SOC).

Area of Science:

  • Complex Systems
  • Evolutionary Game Theory
  • Sociophysics

Background:

  • Traditional Self-Organized Criticality (SOC) models often focus on spatial avalanches.
  • Evolutionary game theory provides a framework for understanding strategy evolution in populations.
  • Sociological and physiological systems exhibit complex emergent behaviors.

Purpose of the Study:

  • To introduce and analyze a novel model of Self-Organized Temporal Criticality (SOTC).
  • To explore the emergence of cooperation in social systems through evolutionary game theory.
  • To compare bottom-up SOTC with top-down global strategy adoption.

Main Methods:

  • Developed a composite network model with interacting subnetworks for strategy choice and payoff.
  • Implemented a dynamic imitation strength (K) based on payoff feedback.
  • Analyzed temporal complexity, specifically non-Poisson renewal events and inverse power law distributions.

Main Results:

  • The SOTC model shows spontaneous evolution towards cooperation despite selfish individual strategy selection.
  • Criticality is signaled by temporal complexity, with inter-event times following an inverse power law (μ = 1.3).
  • Top-down approaches with global rules and leader-driven strategies result in weaker social benefits and impeded self-organization.

Conclusions:

  • SOTC offers a viable bottom-up mechanism for achieving social cooperation.
  • Temporal complexity, not spatial avalanches, characterizes criticality in this model.
  • The SOTC model aligns with recent theoretical frameworks proposed by European social scientists.
