Assessing the Coherence of Parents' Short Narratives Regarding their Child Using the Five-Minute Speech Sample Procedure
Published on: September 19, 2019
Summary
Coherence in quantum and classical physics unifies under a single concept of wave packet interference and uniformity. This principle explains phenomena like self-induced transparency and superconductivity.
Area of Science:
- Quantum physics
- Classical optics
- Wave mechanics
Background:
- The term "coherence" is used diversely in quantum theory and classical optics.
- Existing definitions lack a unified framework connecting these applications.
Purpose of the Study:
- To unify the concept of coherence across quantum and classical physics.
- To establish a single conceptual basis for understanding coherence.
- To link coherence to fundamental properties of wave packets.
Main Methods:
- Reviewing the application of coherence in quantum theory and classical optics.
- Analyzing the mathematical underpinnings of coherence, focusing on interference, uncertainty, and variance.
- Examining specific physical phenomena as case studies.
Main Results:
- Demonstrating that coherence in both domains arises from nonzero interference cross terms.
- Showing coherence relates to minimum uncertainty and uniform variance of the system's wave packet.
- Identifying a unified definition applicable to diverse physical systems.
Conclusions:
- Coherence is a fundamental property related to wave packet behavior.
- The unified concept provides a consistent framework for understanding phenomena like self-induced transparency, superradiance, and superconductivity.

01:07Cohesion
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.

01:38Cognitive Dissonance
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:14Stability of structures
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...
01:23Stability of Equilibrium Configuration
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

Cohesin protein complexes are a molecular glue that holds two sister chromatids together. They play an important role both in mitosis and meiosis. In mitosis, all cohesin complexes present on the chromosomes are removed before the start of the anaphase stage.
Cohesin complexes in Meiotic Division
Meiosis involves two distinct rounds of chromosomal segregation and cell divisions— Meiosis I followed by Meiosis II – producing four daughter cells. Meiosis I includes the separation of homologous...
