Vision01:24

Vision

60.3K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Reliability and Validity01:29

Reliability and Validity

14.1K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Intelligence01:27

Intelligence

8.7K
The term "intelligence" is complex because it refers to both behavior and individuals, and its interpretation varies across cultures. European Americans tend to link intelligence with reasoning and cognitive skills, while in Kenya, it is tied to responsible participation in family and social life. In Uganda, intelligence is seen as the ability to know the right actions and carry them out effectively, while the Iatmul people of Papua New Guinea associate it with the capacity to remember...

Color Vision01:24

Color Vision

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Measures of Intelligence01:29

Measures of Intelligence

8.6K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Area of Science:

  • Surgical Technology
  • Computer Vision
  • Healthcare Economics

Background:

  • Operating room waste, particularly from single-use supplies in robotic surgery, is a significant overlooked cost.
  • Current waste tracking methods rely on manual observation, which is inefficient, inconsistent, and lacks scalability.

Purpose of the Study:

  • To develop and validate a computer vision-based system (AIMs) for automatic detection and quantification of robotic stapler load waste.
  • To assess the accuracy and workflow integration of the AIMs system in a real-world surgical setting.

Main Methods:

  • A prospective validation study involving 18 robotic procedures at a high-volume center.
  • Utilized a convolutional neural network for real-time object detection from continuous back table video recordings.
  • Compared system-generated logs against concurrent manual observations, evaluating sensitivity and precision at critical timepoints.

Main Results:

  • The AIMs system achieved perfect (100%) sensitivity and precision for initial load detection and final waste quantification.
  • Mid-procedure tracking demonstrated high sensitivity (87.7%–97.1%) and perfect (100%) precision for addition and removal events.
  • All errors were false negatives; no false positives were recorded. System operation did not disrupt workflow or require extra staff.

Conclusions:

  • The computer vision-based AIMs system provides accurate, scalable, and objective data for managing surgical supply waste.
  • This technology supports preference card optimization and cost reduction initiatives in robotic surgery programs.
  • Enhanced cost-effectiveness can facilitate broader patient access to advanced robotic surgical technologies.
