Entropy02:39

Entropy

36.2K
Salt particles that have dissolved in water never spontaneously come back together in solution to reform solid particles. Moreover, a gas that has expanded in a vacuum remains dispersed and never spontaneously reassembles. The unidirectional nature of these phenomena is the result of a thermodynamic state function called entropy (S). Entropy is the measure of the extent to which the energy is dispersed throughout a system, or in other words, it is proportional to the degree of disorder of a...

Entropy

3.6K
The first law of thermodynamics is quantitatively formulated via an equation relating the internal energy of a system, the heat exchanged by it, and the work done on it. A quantitative formulation of the second law of thermodynamics leads to defining a state function, the entropy.
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...

Standard Entropy Change for a Reaction

24.9K
Entropy is a state function, so the standard entropy change for a chemical reaction (ΔS°rxn) can be calculated from the difference in standard entropy between the products and the reactants.

Self-Awareness and Its Effects01:21

Self-Awareness and Its Effects

317
Self-awareness is a psychological state in which the individual becomes the focal point of their attention. This inward focus transforms the self into an object of contemplation and assessment, influencing how individuals perceive their actions and their alignment with personal and societal standards.Triggers and Contexts for Self-AwarenessSelf-awareness can be activated by external stimuli that make individuals visually or audibly aware of themselves, such as mirrors, cameras, or recordings.

Mean free path and Mean free time01:22

Mean free path and Mean free time

5.2K
Consider the gas molecules in a cylinder. They move in a random motion as they collide with each other and change speed and direction. The average of all the path lengths between collisions is known as the "mean free path."

Altered States of Awareness01:06

Altered States of Awareness

1.2K
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Area of Science:

  • Computer Science
  • Information Theory
  • Medical Informatics

Background:

  • Entropy is increasingly used to measure knowledge base predictability and redundancy.
  • Existing entropy methods for ontologies overlook path connectivity and assign uniform weights.
  • This limits the accurate evaluation of complex knowledge structures like ontologies.

Purpose of the Study:

  • To introduce an Entropy-Aware Path-Based (EAPB) metric for improved ontology quality assessment.
  • To address limitations of current entropy applications by considering path and textual information.
  • To provide a more reliable method for evaluating ontologies, particularly in medical informatics.

Main Methods:

  • Developed the EAPB metric, integrating path information and textual content for network connectivity.
  • Utilized structure-based and text-based embeddings multiplied by the entropy computation's connectivity matrix.
  • Conducted analytical evaluations against state-of-the-art criteria and empirical analysis on real-world and synthetic ontologies.

Main Results:

  • The EAPB metric effectively evaluates ontology quality, demonstrating reliability through statistical information, entropy evaluation, and case studies.
  • Experimental analysis confirmed the metric's capability, especially for medical informatics ontologies.
  • The approach leverages path and textual information to enrich network representational learning for entropy computation.

Conclusions:

  • The EAPB metric offers a significant advancement in ontology evaluation by incorporating structural and textual data.
  • It benefits semantic web analytics and management of ontology development projects.
  • Results are reproducible, with source code and ontology to be released post-publication.
