Molecular Models

43.9K
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

The Bohr Model02:18

The Bohr Model

81.2K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

Stereotype Content Model02:16

Stereotype Content Model

15.5K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Pharmacodynamic Models: Direct Effect Model and Indirect Response Model

16
Pharmacodynamic models are essential tools in understanding the relationship between drug concentrations and their effects on biological systems. By characterizing the dynamics of drug action, these models guide dose selection, optimize therapeutic efficacy, and inform the development of new drugs. Two major classes of pharmacodynamic models include direct effect and indirect response models.Direct Effect ModelsDirect effect models describe the immediate relationship between drug concentration...

Compartment Models: Two-Compartment Model01:20

Compartment Models: Two-Compartment Model

7.2K
The two-compartment model divides the body into central and peripheral compartments to account for varying blood perfusion rates among organs and tissues, affecting drug distribution. The central compartment includes blood and highly perfused tissues with rapid drug distribution, while the peripheral compartment contains tissues with slower drug distribution. After a single IV bolus dose, the drug concentration is high in plasma and low in tissues. The drug distribution between compartments...

Clearance Models: Physiological Models

330
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

Área de la Ciencia:

  • Ciencias de la Computación
  • Inteligencia Artificial
  • Ciencia Forense

Sus antecedentes:

  • La autenticación de firmas es crucial para verificar la identidad y prevenir el fraude.
  • Los métodos tradicionales pueden ser lentos y subjetivos.
  • El aprendizaje profundo ofrece potencial para la verificación de firmas automatizada y precisa.

Objetivo del estudio:

  • Personalizar un modelo de red neuronal convolucional (CNN) basado en aprendizaje profundo para la autenticación de firmas.
  • Evaluar el rendimiento del modelo en un conjunto de datos de firmas genuinas y falsificadas.

Principales métodos:

  • Se personalizó y entrenó un modelo de red neuronal convolucional (CNN) con 1400 imágenes de firmas (700 genuinas, 700 falsificadas).
  • El conjunto de datos se dividió en conjuntos de entrenamiento (1000 muestras) y prueba (400 muestras).
  • La arquitectura del modelo se optimizó mediante el ajuste de hiperparámetros.

Principales resultados:

  • El modelo logró altas tasas de precisión: 97,32 % (entrenamiento), 97,92 % (validación) y 84,5 % (prueba).
  • Otras métricas de rendimiento incluyeron precisión (85 %), recuperación (84 %), puntuación F1 (84 %) y especificidad (90 %).
  • El modelo propuesto demostró un rendimiento superior en comparación con los métodos existentes.

Conclusiones:

  • La arquitectura CNN personalizada proporciona una solución eficaz para la autenticación de firmas.
  • El modelo puede entrenarse aún más con conjuntos de datos más grandes para mejorar el rendimiento.
  • Las aplicaciones potenciales incluyen el examen de documentos forenses, la banca y los entornos legales.
