Primary Active Transport01:47

Primary Active Transport

206.7K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Current Growth And Decay In RL Circuits

5.1K
The current growth and decay in RL circuits can be understood by considering a series RL circuit consisting of a resistor, an inductor, a constant source of emf, and two switches. When the first switch is closed, the circuit is equivalent to a single-loop circuit consisting of a resistor and an inductor connected to a source of emf. In this case, the source of emf produces a current in the circuit. If there were no self-inductance in the circuit, the current would rise immediately to a steady...

Pole and System Stability01:24

Pole and System Stability

1.3K
The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...

Stability of Equilibrium Configuration01:23

Stability of Equilibrium Configuration

970
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

Summary

Competition among multiple cyclic loops at each site influences nonequilibrium spatiotemporal patterns. Simulations reveal that varying flip energies and network structures control pattern formation, including spiral waves and homogeneous cycling modes.

Area of Science:

  • Complex Systems
  • Statistical Physics
  • Nonlinear Dynamics

Background:

  • Nonequilibrium spatiotemporal patterns are widely studied.
  • Previous models typically use single oscillators or cyclic loops at each site.
  • The influence of multiple interacting cyclic loops remains underexplored.

Purpose of the Study:

  • To investigate how competition among multiple identical cyclic loops at each site affects pattern formation.
  • To explore the role of flip energy and network topology in emergent patterns.
  • To determine if spatial coexistence of states can be controlled.

Main Methods:

  • Simulations using active Potts models on two-dimensional square lattices.
  • Modeling standard Potts interactions between neighboring sites.
  • Varying the number of states in cyclic loops (three-state and four-state) and flip energies.

Main Results:

  • Multiple three-state cycles can form simultaneous spiral waves at high flip energies.
  • At lower energies, spiral waves and homogeneous cycling (HC) modes emerge, with stochastic switching between types.
  • Four-state cycles lead to a dominant state with occasional domain formation of other states.
  • Spiral wave and HC modes can coexist temporally in small systems but not in large systems.

Conclusions:

  • The number of spatially coexisting states is controllable.
  • Flip networks and energies are key parameters for tuning pattern complexity.
  • This work provides insights into controlling complex emergent behaviors in spatially extended systems.
