Competition02:34

Competition

24.8K
When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

Protein Complexes with Interchangeable Parts01:57

Protein Complexes with Interchangeable Parts

2.9K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Protein Complex Assembly02:41

Protein Complex Assembly

16.8K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Complex Numbers01:29

Complex Numbers

The real number system cannot represent the square root of a negative number, which restricts solutions for certain equations, such as quadratics with negative discriminants. To address this, the complex number system was developed, introducing the imaginary unit i, where i = √(-1). This extension allows for the representation of all roots, including those involving negative radicands.A complex number is written in the form x + yi, where x and y are real numbers. Here, x represents the...

Formation of Complex Ions

26.1K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

pre-mRNA Processing02:01

pre-mRNA Processing

57.6K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

Area of Science:

  • Complex systems science
  • Network science
  • Innovation diffusion

Background:

  • Complex contagion processes describe how information or behaviors spread through networks.
  • Understanding competition between spreading entities is vital for innovation adoption and market dynamics.
  • Dual users, individuals adopting multiple technologies, play a significant role in market evolution.

Purpose of the Study:

  • To analyze the competitive dynamics between two spreading entities in complex networks.
  • To investigate the impact of dual users on the spread of innovations and the extinction of existing technologies.
  • To identify conditions favoring the adoption of new innovations over established ones.

Main Methods:

  • Development of an analytical framework to model competition between spreading entities.
  • Examination of contagion processes in complex networks.
  • Analysis of spreading and extinction transitions based on network properties and user behavior.

Main Results:

  • Competition with existing technologies suppresses new innovation spread but allows for coexistence phases.
  • Dual users significantly alter transient dynamics, creating new phases that favor new innovation spread and old technology extinction.
  • New innovations can achieve global spread even when existing technologies have a first-mover advantage, due to dual users.

Conclusions:

  • Dual users are critical agents in modifying competition dynamics within complex contagion processes.
  • The presence of dual users can create pathways for disruptive innovations to succeed against established market leaders.
  • Network structure, technology prevalence, and contagion thresholds collectively determine the outcome of innovation competition.
