Diffusion01:12

Diffusion

221.8K
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

6.6K
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...

Protein Networks02:26

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 Solids

16.2K
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...

Facilitated Diffusion01:16

Facilitated Diffusion

1.3K
The plasma membrane, a critical structure in cellular biology, houses an array of transporters, or carrier proteins, interspersed within its lipid bilayer. These proteins play a crucial role in solute transport through facilitated diffusion, a form of passive diffusion that uses transporters to move the molecules across the membrane.
In this process, substrates such as organic compounds and ions interact with a transporter on one side, triggering conformational changes in proteins that enable...

Area of Science:

  • Social Network Analysis
  • Information Diffusion Studies
  • Human-Computer Interaction

Background:

  • Micro-blogging platforms are crucial for information sharing.
  • User interactions like forwarding are well-studied, but the 'mention' feature's impact is less explored.
  • Mentions enhance message visibility and direct communication beyond network structure.

Purpose of the Study:

  • To empirically investigate the effect of mentions on information diffusion in micro-blogging systems.
  • To analyze factors influencing user response probability to mentions.
  • To develop a model for predicting user responses to mentions.

Main Methods:

  • Analysis of a large-scale social media dataset.
  • Examination of the relationship between the number of mentions and response probability.
  • Investigation of follower count, reciprocal relationships, and social status on mention effectiveness.
  • Formulation of a response prediction task as a binary classification problem.

Main Results:

  • Users with more followers receive significantly more mentions.
  • Response probability to a message shows saturation around five mentions.
  • Reciprocal followship and similar social status increase the likelihood of a user's response.
  • Discovered factors effectively predict user responses.

Conclusions:

  • Mentions play a significant role in information diffusion on social media.
  • Understanding mention dynamics is key to human behavior on social networks.
  • Findings have implications for viral marketing and public opinion monitoring.
