Conformity01:20

Conformity

47.9K
Conformity is the change in a person’s behavior to go along with the group, even if that person does not agree with the group.

Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

225
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Conformations of Butane02:20

Conformations of Butane

17.8K
Unlike ethane and propane that have only two major conformations, butane has more than two conformers. The staggered form of butane in which the bulky methyl groups on the two carbons are placed on opposite sides, that is, at a dihedral angle of 180°, is the lowest energy, most stable form — called the anti conformer. This conformation is stabilized due to the absence of steric repulsion between the largely spaced out methyl groups. The other two staggered conformations are...

Conservation of Small Populations02:04

Conservation of Small Populations

16.7K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Theory of Attribution I: Correspondent Inference Theory01:15

Theory of Attribution I: Correspondent Inference Theory

485
Correspondent inference theory, proposed by Jones and Davis in 1965, seeks to explain how individuals infer stable personality traits from observed behaviors. It suggests that people attribute actions to underlying dispositions rather than external circumstances, particularly when the behavior appears intentional and socially significant.Voluntary Behavior and Dispositional AttributionAccording to this theory, individuals are more likely to attribute behavior to personal traits when it appears...

What is Population Genetics?01:25

What is Population Genetics?

64.5K
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.

Sus antecedentes:

  • Las predicciones teóricas precisas de los conjuntos moleculares dependen de modelos directos (FM) precisos.
  • Los métodos existentes luchan por reconciliar la dinámica molecular simulada con datos experimentales, especialmente con observaciones escasas o ruidosas.
  • El refinamiento de los parámetros empíricos del FM es crucial para mejorar la precisión de estas predicciones.

Conclusiones:

  • El algoritmo BICePs mejorado refina eficazmente los parámetros del FM, mejorando la concordancia entre las predicciones teóricas y las mediciones experimentales.
  • Este enfoque ofrece un método robusto para la validación y optimización de campos de fuerza.
  • El marco generalizado proporciona una dirección prometedora para el entrenamiento y la validación de FMs avanzados basados en redes neuronales.
