Gain01:15

Gain

410
Gain and phase shift are properties of linear circuits that describe the effect a circuit has on a sinusoidal input voltage or current. The circuit's behavior that contains reactive elements will depend on the frequency of the input sinusoid. As a result, it is observed that the gain and phase shift will all be frequency functions.
Gain:
Suppose Vin is the input and Vout is the output signal to a circuit.

Defining Psychology

7.8K
Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...

Defining Social Psychology

435
Social psychology investigates how the presence and actions of others influence individual behavior, cognition, and emotion. Examining the social environment's impact provides a scientific framework for understanding how individuals perceive others and are, in turn, influenced by them. This field seeks to uncover the underlying principles guiding social interactions, exploring phenomena such as conformity, obedience, and prosocial behavior.Core Themes in Social PsychologyOne central focus of...

Piecewise-Defined Functions01:28

Piecewise-Defined Functions

289
Piecewise defined functions are mathematical models where different expressions define a function over distinct intervals of the domain. These functions are useful for representing systems with varying behaviors depending on input values.For example, the function:  uses a linear rule for inputs less than or equal to –1 and a quadratic rule for values greater than –1. Although it has two formulas, it still defines a single function.Another common type is the absolute value...

What is Population Genetics?01:25

What is Population Genetics?

64.7K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Area of Science:

  • Immunology
  • Dermatology
  • Microbiology

Background:

  • Atopic dermatitis (AD) involves severe itch, eczema, and chronic skin barrier dysfunction.
  • Key factors in AD pathogenesis include TH2 inflammation and scratching.
  • Alterations in the skin microbiome further complicate AD development.

Purpose of the Study:

  • To review current understanding of atopic dermatitis etiology using mouse models.
  • To explore how mouse models elucidate epidermal barrier function, skin microbiome, TH2 immune responses, and pruritus in AD.

Main Methods:

  • Review of recent scientific literature focusing on mouse models of atopic dermatitis.
  • Analysis of studies investigating epidermal barrier, skin microbiome, TH2 immunity, and pruritus.

Main Results:

  • Mouse models provide valuable data on AD pathophysiology, including skin barrier impairment and TH2 inflammation.
  • Studies using mouse models highlight the role of the skin microbiome in AD.
  • Research in mouse models contributes to understanding the mechanisms of pruritus in AD.

Conclusions:

  • Mouse models are instrumental in dissecting the complex pathophysiology of atopic dermatitis.
  • Despite anatomical and immunological differences, mouse models offer significant insights into AD etiology.
  • Further research using mouse models can advance therapeutic strategies for AD.
