Binomial Probability Distribution01:15

Binomial Probability Distribution

15.4K
A binomial distribution is a probability distribution for a procedure with a fixed number of trials, where each trial can have only two outcomes.
The outcomes of a binomial experiment fit a binomial probability distribution. A statistical experiment can be classified as a binomial experiment if the following conditions are met:
There are a fixed number of trials. Think of trials as repetitions of an experiment. The letter n denotes the number of trials.
There are only two possible outcomes,...

DNA Base Pairing

Erwin Chargaff’s rules on DNA equivalence paved the way for the discovery of base pairing in DNA. Chargaff’s rules state that in a double-stranded DNA molecule,

Negative Regulator Molecules

38.3K
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Per-Unit Sequence Models

440
An ideal Y-Y transformer, grounded through neutral impedances, displays per-unit sequence networks akin to those of a single-phase ideal transformer when subjected to balanced positive- or negative-sequence currents. These currents do not produce neutral currents, and their associated voltage drops.
Zero-sequence currents, which are identical in magnitude and phase, generate a neutral current, resulting in voltage drops across the neutral impedance and the low-voltage winding. If the...

Transcription Factors02:16

Transcription Factors

82.3K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Área de la Ciencia:

  • Investigación de microbioma
  • Modelado estadístico
  • Bioinformática

Sus antecedentes:

  • Los datos de secuenciación de microbioma con frecuencia involucran múltiples sitios corporales.
  • Estos datos multisitio a menudo exhiben dependencias inherentes.
  • Los modelos existentes pueden no capturar completamente estas correlaciones entre sitios.

Objetivo del estudio:

  • Desarrollar un modelo estadístico para el análisis conjunto de datos de microbioma multisitio.
  • Capturar y aprovechar las dependencias subyacentes entre sitios.
  • Mejorar la precisión y la eficiencia en el análisis de datos de microbioma.

Principales métodos:

  • Un modelo de factores latentes que incorpora factores compartidos entre sitios.
  • Modelado de efectos comunes del sujeto y correlaciones entre sitios.
  • Utilización de mezclas de factores latentes para la heterogeneidad del sujeto en las asociaciones.

Principales resultados:

  • Ignorar las dependencias del sitio conduce a una pérdida significativa de eficiencia en el análisis de regresión.
  • El modelo propuesto detectó asociaciones significativas de covariables entre los microbiomas vaginal y urinario en un estudio urogenital femenino.
  • Estas asociaciones no fueron significativas cuando los sitios se analizaron por separado.

Conclusiones:

  • Se propone un nuevo modelo de factores latentes para datos de microbioma multisitio.
  • El modelo captura con precisión las asociaciones entre sitios sin comprometer la eficiencia estadística.
  • Mejora el rendimiento predictivo al permitir la predicción de la abundancia microbiana entre sitios.
  • Un marco extendido permite la agrupación y clasificación de sujetos por fuerza de asociación.
