Summary
Correlated bursts in temporal networks slow down disease spreading. This study shows positive interevent time correlations reduce spread, explained by shortest transmission times.
Area of Science:
- Complex Systems
- Network Science
- Epidemiology
Background:
- Spreading dynamics in temporal networks exhibit non-Poissonian bursty interactions.
- Inhomogeneous interevent times (IETs) effects are studied, but IET correlations remain underexplored.
Purpose of the Study:
- Investigate the impact of correlated interevent times on spreading dynamics.
- Analyze susceptible-infected (SI) dynamics under correlated bursty interactions.
Main Methods:
- Studied two-step deterministic and probabilistic SI dynamics.
- Modeled interaction patterns using inhomogeneous and correlated IETs (correlated bursts).
- Analyzed transmission time statistics and simulated spreading on Bethe lattices and random graphs.
Main Results:
- Positive correlation between interevent times was found to slow down spreading dynamics.
- Numerical results were successfully explained by the shortest transmission time from infected to susceptible nodes.
Conclusions:
- Correlated bursts in temporal networks significantly alter spreading behavior.
- Shortest transmission time is a key factor in understanding spread reduction due to IET correlations.

35.9K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

02:25Spreading of Chromatin Modifications
9.5K
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.

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

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,...

02:05Gene Evolution - Fast or Slow?
8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...
