The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

55.5K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Conservation of Protein Domains Over Different Proteins

14.1K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Classification of Titrimetric Analysis Based on Reaction Types

1.5K
Titrimetric analysis in solution chemistry involves measuring the volume of solutions and is often called volumetric analysis. The standard solution of known concentration in the burette is called the titrant, whereas the solution of unknown concentration in the flask is called the analyte, or titrand. Titrimetric analyses can be classified into four types based on the reactions between the titrant and analyte.
Titrations between an acid and a base lead to neutralization reactions that form...

Cardiovascular Drugs: Classification based on Therapeutic Indications

4.1K
Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

Leveling Effect and Non-Aqueous Acid-Base Solutions

9.4K
This lesson defines the leveling effect in acidic and basic solutions and its role in aqueous and non-aqueous solutions. It is essential to understand the competing nature of various species in a chemical system.
The Leveling Effect of a Solvent
A generic acid (HA) reacts with the generic base (B-) to yield the corresponding conjugate base (A-) and conjugate acid (HB):

Components of Stress01:23

Components of Stress

509
Stress analysis under multiple loading conditions is intricate, necessitating a comprehensive grasp of normal and shearing stresses. Consider a small cube at point O, subjected to stress on all six faces, visible or not. Normal stress components σx, σy, σz act perpendicularly to the x, y, and z axes. Shearing stress components τxy and τxz are exerted on faces perpendicular to these axes.
Interestingly, the hidden cube faces also experience these stresses, equal and...

Área de la Ciencia:

  • Teledetección
  • Visión por Computadora
  • Procesamiento de Imágenes

Sus antecedentes:

  • Las imágenes hiperespectrales (HSI) enfrentan desafíos como la "homogeneidad" y la "heterogeneidad", que causan baja consistencia intra-clase y pobre diferenciación inter-clase.
  • Los métodos de clasificación existentes luchan por integrar la estructura global y los detalles locales de la información espacial-espectral, lo que afecta el rendimiento.
  • Abordar estos problemas es crucial para la clasificación precisa de características de imágenes HSI.

Objetivo del estudio:

  • Proponer un nuevo método de clasificación de imágenes hiperespectrales de detección remota, D²FuPro.
  • Aprovechar la complementariedad a nivel de dominio de los componentes espaciales-espectrales para mejorar la clasificación.
  • Mejorar la consistencia intra-clase y la diferenciación inter-clase en la clasificación HSI.

Principales métodos:

  • Se emplea una estructura de doble rama para capturar información espacial-espectral global (dominio panorámico) y local (dominio mesoscópico).
  • La Extracción de Características de Bajo Rango de Dominio Panorámico (PLFE) preserva la estructura global a través de la modelización de bajo rango y el suavizado de texturas.
  • La Mejora de Características de Dominio Mesoscópico (MDFE) optimiza la información espectral local y los límites espaciales utilizando el contexto de píxeles vecinos.

Principales resultados:

  • El método D²FuPro integra eficazmente información espacial-espectral dual-dominio, logrando beneficios complementarios.
  • La validación experimental en cuatro conjuntos de datos muestra un rendimiento superior en comparación con métodos tradicionales y avanzados.
  • El método propuesto demuestra mejoras significativas en la precisión de la clasificación.

Conclusiones:

  • D²FuPro aborda con éxito los problemas de homogeneidad y heterogeneidad en la clasificación HSI.
  • El enfoque de doble dominio mejora la integración de características espaciales-espectrales globales y locales.
  • Este método ofrece un avance prometedor para la precisión de la clasificación de imágenes hiperespectrales.
