Correlations02:20

Correlations

35.9K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Correlation and Causation

42.7K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Correlation

15.1K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Machines

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

Área de la Ciencia:

  • Oftalmología y Salud Cardiovascular
  • Imágenes y Diagnóstico Médico
  • Ingeniería Biomédica

Sus antecedentes:

  • El diagnóstico de placa carotídea es crucial para identificar enfermedades cardiovasculares y cerebrovasculares.
  • Los métodos de diagnóstico actuales, como el ultrasonido carotídeo, consumen mucho tiempo, son radiativos, costosos y limitan el seguimiento de la progresión de la enfermedad.
  • Existe la necesidad de métodos accesibles y no invasivos para la detección y el seguimiento de la placa carotídea.

Objetivo del estudio:

  • Investigar la asociación entre la placa carotídea y las características de la imagen de la superficie ocular.
  • Desarrollar un método de detección no invasivo para placas carotídeas utilizando imágenes oculares.
  • Explorar el potencial del análisis de imágenes de la superficie ocular en la evaluación de la salud cardiovascular.

Principales métodos:

  • Análisis multidimensional de características de imágenes de la superficie ocular, incluidas características de textura, dominio de frecuencia y color.
  • Selección de características, evaluación de confianza y estudios de propiedades de distribución para establecer asociaciones sólidas.
  • Clasificadores de aprendizaje automático y validación de subgrupos (edad, género) para evaluar la solidez de las características y el rendimiento predictivo.

Principales resultados:

  • Se logró una alta precisión predictiva en una cohorte de 8875 individuos.
  • Las características del registro electrónico de salud (EHR) mostraron la asociación más fuerte con la placa carotídea (OR: 4,35 en hombres, 2,92 en mujeres).
  • Las características de la imagen de la superficie ocular (EHR, LBP, GLGCM, GLCM), la edad y el género masculino se asociaron fuertemente con la placa carotídea.

Conclusiones:

  • El análisis de imágenes de la superficie ocular proporciona un enfoque práctico y no invasivo para la detección de placas carotídeas.
  • Las asociaciones de características identificadas y el rendimiento predictivo respaldan las aplicaciones clínicas, particularmente para el cribado de poblaciones a gran escala.
  • Este método tiene el potencial de complementar las herramientas de diagnóstico existentes para la evaluación del riesgo cardiovascular.
