Diffusion01:12

Diffusion

222.3K
Diffusion is the passive movement of substances down their concentration gradients—requiring no expenditure of cellular energy. Substances, such as molecules or ions, diffuse from an area of high concentration to an area of low concentration in the cytosol or across membranes. Eventually, the concentration will even out, with the substance moving randomly but causing no net change in concentration. Such a state is called dynamic equilibrium, which is essential for maintaining overall...

Diffusion

6.7K
Diffusion is a type of passive transport. In passive transport, a substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. For example, take the diffusion of substances through the air. When someone opens a perfume bottle in a room filled with people, the perfume is at its highest concentration in the bottle and is at its lowest at the edges of the room. The perfume vapor will diffuse, or spread away, from the...

The Eukaryotic Promoter Region

19.0K
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences.  The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

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,...

Network Covalent Solids02:18

Network Covalent Solids

16.3K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Area of Science:

  • Complex networks
  • Information diffusion dynamics
  • Epidemic modeling

Background:

  • Interlayer contagion effects on spreading in multiplex networks are known.
  • The impact of interlayer recovery processes on information diffusion remains unclear.

Purpose of the Study:

Main Methods:

  • Developed a modified ignorant-spreader-stifler model incorporating interlayer recovery.
  • Combined mean-field approximation and Markov chain approach for analysis.
  • Derived evolution equations for two-layer homogeneous multiplex networks.

Main Results:

  • Information diffusion is effectively promoted by interlayer recovery mechanisms.
  • Optimal interlayer recovery rates were identified and calculable.
  • Cross-layer information spread significantly influences diffusion enhancement.

Conclusions:

  • Interlayer recovery is beneficial for information diffusion in multiplex networks.
  • Findings suggest potential for designing more efficient spreading strategies.
  • The model's applicability extends to scale-free networks with or without degree correlation.
