Distribution Reliability and Automation01:25

Distribution Reliability and Automation

515
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Overview of DNA Repair

33.7K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

The de Broglie Wavelength

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

The Anchoring-and-Adjustment Heuristic

7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Reason and Intuition01:37

Reason and Intuition

7.5K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Area of Science:

  • Computational neuroscience
  • Bioinformatics
  • Data science

Background:

  • Knowledge discovery relies on complete data and metadata.
  • Manual metadata curation is time-consuming and limited by expertise.
  • Diverse research needs create complex metadata schemes, challenging automated annotation.

Purpose of the Study:

  • To develop an automated method for improving metadata completeness in informatics resources.
  • To reduce the burden on human curators by leveraging existing data.
  • To enhance the discoverability of computational models and data.

Main Methods:

  • Implemented manually-curated, regular-expression-based rules to parse user-provided text.
  • Developed a system to suggest metadata annotations during data entry in the ModelDB resource.
  • Analyzed the precision and recall of metadata suggestions from different text sources (abstract, full-text, title).

Main Results:

  • Parsing abstracts suggested an average of 6.4 metadata tags per entry with 79% precision.
  • Full-text analysis yielded higher recall but lower precision (41%).
  • Metadata suggestion effectiveness varied across different annotation categories.

Conclusions:

  • Automated metadata suggestion using text parsing can significantly improve informatics resource completeness.
  • Prompting data providers with relevant metadata during upload is an effective strategy.
  • This approach offers a cost-effective method for other bioinformatics resources to enhance metadata quality.
