Summary
This study explores epidemic and awareness spreading on complex networks. A metacritical point, crucial for epidemic onset, disappears with mass media awareness broadcasts.
Area of Science:
- Complex systems
- Network science
- Epidemiology
Background:
- Epidemic spreading on multilayered networks involves competing processes.
- Previous work identified a metacritical point in awareness-driven immunization scenarios.
- Generalizing competition dynamics is essential for understanding real-world outbreaks.
Purpose of the Study:
- To analyze critical properties of epidemic and awareness spreading in a general scenario.
- To investigate the impact of non-total immunization and delayed awareness.
- To determine the effect of mass media on epidemic incidence and metacritical points.
Main Methods:
- Analysis of epidemic and awareness spreading dynamics on multiplex networks.
- Investigation of phase diagrams and critical transitions.
- Modeling the influence of mass media on information dissemination.
Main Results:
- A critical relation between competing epidemic and awareness processes was established.
- The metacritical point, dependent on awareness completion, was analyzed generally.
- Mass media broadcasts were shown to eliminate the metacritical point.
Conclusions:
- The existence of a metacritical point is fundamentally linked to the competition principle.
- Network structure and awareness strategies significantly influence epidemic outcomes.
- Mass media can alter epidemic dynamics by disrupting critical transition points.

1.1K
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

1.4K
The analysis of suspension bridges is a complex and critical process that involves multiple factors, including the shape and tension of the main cables. The main cables of suspension bridges are subjected to distributed loads, which result in changes in tensile forces and deformation of the cable. These loads must be carefully considered to ensure that the bridge is safe and capable of supporting the weight of different loads.

02:25Spreading of Chromatin Modifications
8.1K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

01:26Microbial Interactions: Competition
86
Microbial competition is an ecological interaction in which microorganisms vie for limited resources within shared environments. These resources may include nutrients, space, or light, depending on the system. The intensity and outcome of competition are influenced by the environmental context, such as nutrient availability, spatial constraints, and the diversity of microbial species present. These competitive interactions significantly influence the structure, function, and resilience of...

When protons A and X are coupled, their nuclear spin energy levels are slightly modified. This is because the energy required to excite proton A to a spin state parallel to proton X is slightly different from the energy required for it to become anti-parallel to spin X. Consequently, there are two possible excitation frequencies for A (A1 and A2), depending on the spin state of X, and vice versa. The mutual nature of coupling implies that the difference between frequencies A1 and A2, indicated...
