¹H NMR: Interpreting Distorted and Overlapping Signals

¹H NMR: Interpreting Distorted and Overlapping Signals

Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

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,...

Finding the Center of Gravity

Finding the Center of Gravity

The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Network Covalent Solids

Network Covalent Solids

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...

Area of Science:

Network Science
Data Mining
Complex Systems

Background:

Understanding multilayer networks is crucial for analyzing complex systems, with each layer representing distinct relationships.
Existing community discovery methods often overlook inter-layer dynamics or individual layer topology, and typically fail to detect overlapping communities.

Purpose of the Study:

To propose a novel community discovery method for multilayer networks that effectively captures inter-layer interplay and unique layer topology.
To enable the detection of overlapping communities within multilayer network structures.

Main Methods:

Calculated edge similarities within and across layers, considering both intra-layer and inter-layer behaviors.
Constructed a dendrogram for multilayer networks integrating unique topological structures and inter-layer dynamics.
Introduced a new community density metric to cut the dendrogram and identify overlapping communities.

Main Results:

The proposed method successfully identifies overlapping communities in multilayer networks.
Demonstrated accurate performance on both synthetic and real-world datasets.

Conclusions:

The developed method provides an effective approach for discovering overlapping communities in multilayer networks.
It highlights the importance of considering both inter-layer relationships and intra-layer topology for accurate community detection.
