Summary
This study introduces temporal Boolean networks (TBNs) for modeling biological systems with dynamic connections. New methods using incidence matrices significantly reduce computational complexity for analyzing TBN stability.
Area of Science:
- Systems Biology
- Network Dynamics
- Computational Neuroscience
Background:
- Biological functionalities often depend on dynamic, time-varying connections.
- Existing models may not fully capture the temporal aspects of biological networks.
- Temporal Boolean networks (TBNs) offer a framework for such dynamic systems.
Purpose of the Study:
- To analyze the fast-time stability of temporal Boolean networks (TBNs).
- To develop computationally efficient methods for stability analysis and control of TBNs.
- To investigate global and local fast-time stability and stabilization strategies.
Main Methods:
- Utilizing the semi-tensor product (STP) of matrices to derive the algebraic form of TBNs.
- Employing incidence matrices to derive stability conditions, reducing computational complexity.
- Designing pinning controllers based on network neighbors for global stabilization.
Main Results:
- A necessary and sufficient condition for global fast-time stability was established using STP.
- Sufficient conditions derived from incidence matrices reduce complexity from exponential to polynomial (O(n^4)).
- Effective pinning controllers were designed for global fast-time stabilization.
- Local fast-time stability analysis was also performed using incidence matrices.
Conclusions:
- The proposed methods provide efficient tools for analyzing and controlling TBNs.
- Incidence matrices offer a significant computational advantage over traditional STP methods for stability analysis.
- The findings are crucial for understanding and engineering complex biological systems with dynamic interactions.

System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....

23.2K
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

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,...

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

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...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
