Hybridization of Atomic Orbitals I03:24

Hybridization of Atomic Orbitals I

47.6K
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Hybridoma Technology

15.1K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Synthetic Biology

4.9K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Structure of Benzene: Molecular Orbital Model01:18

Structure of Benzene: Molecular Orbital Model

9.6K
According to the molecular orbital (MO) model, benzene has a planar structure with a regular hexagon of six sp2 hybridized carbons. As shown in Figure 1, each carbon is bonded to three other atoms with C–C–C and H–C–C bond angles of 120°. The C–H bond length is 109 pm, and the C–C bond length is 139 pm which is midway between the single bond length of sp3 hybridized carbons (154 pm) and sp2 hybridized carbons (133 pm).

Background:

  • Mechanistic models in systems biology are often represented in Systems Biology Markup Language (SBML).
  • Integrating machine learning (ML) with mechanistic models offers enhanced analytical capabilities.
  • A gap exists in tools facilitating the conversion and management of such hybrid models.

Purpose of the Study:

  • To introduce sbml2hyb, a Python tool for converting SBML models to hybrid semiparametric models.

  • To enhance the adoption of hybrid modeling techniques in biological systems analysis.

Main Methods:

  • Developed sbml2hyb as a standalone Python tool.
  • Implemented conversion of SBML models to hybrid models combining mechanistic functions and ML.
  • Designed the HMOD format to integrate mechanistic and ML components, adhering to SBML standards.
  • Validated the tool through two case studies.

Main Results:

  • sbml2hyb successfully converts mechanistic SBML models into hybrid models.
  • Hybrid models can be trained and stored back in SBML format.
  • The HMOD format effectively supports the aggregation of mechanistic and ML model information.
  • The tool and format facilitate the creation and use of hybrid models.

Conclusions:
