Summary
This study shows how efficient motors in a robotic fish demonstrate the benefits of burst-and-coast swimming. This swimming style conserves energy for aquatic robots and animals.
Area of Science:
- Robotics
- Biomimetics
- Fluid Dynamics
Background:
- Burst-and-coast swimming is a common locomotion strategy observed in many aquatic animals.
- Understanding the efficiency of this swimming style can provide insights into animal locomotion and robotic design.
Purpose of the Study:
- To investigate the motor efficiency of a zebrafish-like robot.
- To elucidate the advantages of burst-and-coast swimming through robotic emulation.
Main Methods:
- A robotic model mimicking zebrafish swimming dynamics was developed.
- Motor efficiency was analyzed during simulated burst-and-coast swimming gaits.
Main Results:
- The robotic model demonstrated significant energy savings using the burst-and-coast strategy.
- Peak motor efficiency was achieved during the 'coast' phase, with reduced energy expenditure.
Conclusions:
- The findings support the hypothesis that burst-and-coast swimming is an energetically advantageous locomotion method.
- Robotic models can effectively replicate and explain biological swimming principles, aiding in the design of efficient aquatic vehicles.

01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
251
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Carbohydrates are an essential part of the diet in humans and animals. Grains, fruits, and vegetables are natural sources of carbohydrates that provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. The stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule represents carbohydrates. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This...

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...
