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,...

Classification of Systems-I

Classification of Systems-I

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Classification of Neurotransmitters

Classification of Neurotransmitters

Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Classification of Systems-II

Classification of Systems-II

Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Sequence Networks of Rotating Machines

Sequence Networks of Rotating Machines

A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Background:

Biological systems are commonly modeled using graphs, representing objects and their relationships.
Traditional graph models can lead to information loss when representing complex, multi-object relationships.
Hypergraphs offer a generalized framework to overcome these limitations in biological network analysis.

Purpose of the Study:

To develop a hypergraph-based approach for modeling biological systems.
To formulate key network analysis problems (vertex/edge classification, link prediction) within a hypergraph framework.
To introduce a novel kernel method for analyzing vertex- and edge-labeled hypergraphs.

Main Methods:

Formulation of biological network problems as vertex classification on extended or dual hypergraphs.
Development of a novel kernel method based on hypergraphlet enumeration (exact and inexact).
Utilized hypergraph edit distances for inexact hypergraphlet enumeration.

Main Results:

Empirical evaluation on fifteen diverse biological networks.
Demonstrated the potential of the hypergraph kernel method for biological network analysis and learning.
Showcased utility in a positive-unlabeled learning setting for interactome size estimation.

Conclusions:

Hypergraphs provide a more comprehensive framework for modeling biological systems than traditional graphs.
The proposed hypergraph kernel method is effective for analyzing complex biological networks.
This approach has practical applications in estimating biological network properties like interactome size.
