Summary
This study introduces an integrated granularity framework for ontologies, addressing limitations in managing complex biomedical data. The new framework enhances data querying by allowing multiple perspectives and levels of detail for material entities.
Area of Science:
- Ontology Engineering
- Biomedical Informatics
- Knowledge Representation
Background:
- Current ontology granularity theories limit performance and data integration.
- Existing schemes fail to accommodate multiple granularity perspectives simultaneously.
- Existing schemes are not suitable for cumulative-constitutively organized material entities, common in biomedicine.
Purpose of the Study:
- To develop an integrated granularity framework for ontologies.
- To address limitations of existing granularity theories for biomedical data.
- To enable consistent modeling of complex material entities.
Main Methods:
- Utilized the Basic Formal Ontology (BFO) as a top-level ontology.
- Applied Keet's general theory of granularity.
- Integrated multiple compositional and spatial granularity perspectives.
Main Results:
- Developed a framework applicable to cumulative-constitutively organized material entities.
- Enabled granulation into constitutive and regional parts.
- Integrated scale-dependent resolution and measurement-based perspectives.
- Provided a unified framework connecting diverse granularity levels.
Conclusions:
- The framework offers a consistent spatio-structural granularity for domain reference ontologies.
- Enables multi-perspective querying of ontologies at various detail levels.
- Facilitates diverse organization and views of database content (data, knowledge).

01:18Structural Organization of the Human Body: An Overview
It is convenient to consider the body's structures in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms.
To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms, and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of...

01:07Electron Microscope Tomography and Single-particle Reconstruction
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.

01:09Levels of Organization
Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules comprise...
01:29Microbial Morphologies
Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...
01:10X-ray Diffraction of Biological Samples
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

01:18Imaging Biological Samples with Optical Microscopy
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
