Protein Networks

Protein Networks

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,...

Stability of structures

Stability of structures

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Trait Centrality

Trait Centrality

Trait centrality refers to the degree to which a particular characteristic influences the overall impression of an individual. Some traits exert a disproportionately strong impact on perception, shaping how people interpret other attributes of a person. Solomon Asch first systematically studied this phenomenon in 1946.Asch’s Experiment on Trait CentralityAsch's seminal study demonstrated the centrality of certain traits through a controlled experiment. Participants were presented with a list of...

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Outliers and Influential Points

Outliers and Influential Points

An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the vertical...

Area of Science:

Network Science
Systems Biology
Computer Science

Background:

Complex systems are often modeled as networks with vertices and edges.
System robustness to component failure is a critical research area.
Network structure integrity is key to system functionality.

Purpose of the Study:

To investigate the impact of targeted vertex removal on network structure.
To extend previous studies on network robustness by exploring new removal strategies.
To analyze the effect of targeted removal on networks with diverse properties.

Main Methods:

Analyzing network structure changes under vertex removal.
Implementing targeted vertex removal based on non-local importance measures.
Testing strategies on model networks with varying degree distributions, clustering, and assortativity coefficients.
Evaluating strategies on empirical networks.

Main Results:

Targeted vertex removal significantly impacts network structure and robustness.
Non-local importance measures offer alternative strategies for assessing network vulnerability.
Network properties like degree distribution and clustering influence resilience to targeted attacks.

Conclusions:

Understanding network vulnerability requires considering targeted removal strategies beyond simple degree or betweenness.
The choice of vertex removal strategy critically affects the assessment of network robustness.
Further research is needed to develop comprehensive models for predicting system resilience.
