Sign Test for Matched Pairs01:17

Sign Test for Matched Pairs

394
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

Wilcoxon Signed-Ranks Test for Matched Pairs01:09

Wilcoxon Signed-Ranks Test for Matched Pairs

489
The Wilcoxon signed-rank test for matched pairs evaluates the null hypothesis by combining the ranks of differences with their signs. It essentially tests whether the median of the differences in a population of matched pairs is zero. Since the test incorporates more information than the sign test, it generally yields more trustable conclusions. This test also does not require the data to follow a normal distribution, but two conditions must be met for it to be applicable: (1) the data must...

Predator-Prey Interactions02:39

Predator-Prey Interactions

21.2K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Van der Waals Interactions01:24

Van der Waals Interactions

71.0K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

piRNA - Piwi-interacting RNAs

7.6K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Drug-Receptor Interactions01:29

Drug-Receptor Interactions

7.4K
Drug-receptor interaction describes the binding of receptors by drugs, but not all drug-receptor interactions result in activation and tissue response. For instance, the binding of agonists activates the receptor to generate a cellular reaction, while antagonists bind to receptors without causing their activation.
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue....

Area of Science:

  • Biomedical Informatics
  • Computational Biology
  • Data Science

Background:

  • Biomedical data is rapidly evolving, leading to larger and more complex ontologies.
  • Semantic interoperability requires identifying correspondences between overlapping information in biomedical ontologies (biomedical ontology matching).
  • Challenges include the large scale of ontologies (tens of thousands of entities) and complex, ambiguous biomedical terminology.

Purpose of the Study:

  • To propose an efficient and interactive approach for biomedical ontology matching.
  • To enhance the performance of automatic matching processes by incorporating user feedback.
  • To improve the quality and efficiency of creating high-quality semantic alignments.

Main Methods:

  • Utilized an Evolutionary Algorithm (EA) for automatic matching.
  • Developed an Evolutionary Tabu Search (ETS) algorithm, integrating Tabu Search as a local search strategy to enhance EA performance.
  • Implemented an interactive system where user input guides the evolving matching process, with EA's survival of the fittest filtering erroneous validations.

Main Results:

  • The interactive ETS-based approach significantly improves matching efficiency and alignment quality compared to non-interactive methods.
  • Experimental results on OAEI Anatomy and Large Biomedic tracks demonstrate superior performance over state-of-the-art semi-automatic systems.
  • The system effectively leverages user intervention to refine ontology alignments.

Conclusions:

  • The proposed interactive biomedical ontology matching approach is efficient and effective.
  • Integrating user feedback with evolutionary algorithms and tabu search enhances the quality of semantic alignments.
  • This method offers a promising solution for improving semantic interoperability in biomedical systems.
