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,...

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...

Network Function of a Circuit

Network Function of a Circuit

Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

Sustainable Development

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

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...

Summary

Brain network hubs develop structurally early but functionally later. Structural hubs mature through adolescence, while functional hubs shift from primary to association areas, indicating postnatal brain maturation.

Neuroscience
Developmental Neuroscience
Network Science

Background:

Brain regions acting as network hubs are crucial for integrated brain function.
Understanding the developmental trajectory of these hubs is essential for comprehending brain maturation.

Purpose of the Study:

To review evidence on the developmental emergence and consolidation of structural and functional brain network hubs.
To explore how these hubs shape the developing brain's function across prenatal, neonate, childhood, and adolescent periods.

Main Methods:

Review of existing literature on brain network hub development.
Analysis of studies examining structural and functional connectivity networks across different developmental stages.

Main Results:

Structural brain network hubs emerge prenatally with consistent topography, consolidating into late adolescence.
Functional brain network hubs show variable topography, shifting from primary cortical areas in early development to association areas by late childhood.
Evidence suggests early establishment of anatomical hub infrastructure with significant postnatal functional maturation.

Conclusions:

The development of brain network hubs involves early structural formation and prolonged functional maturation.
Discrepancies in findings highlight the need to address methodological factors in studying brain network development.
Further rigorous investigation is required to fully elucidate the developmental dynamics of brain network hubs.
