¹³C NMR: ¹H–¹³C Decoupling

1.9K
The probability of having two carbon-13 atoms next to each other is negligible because of the low natural abundance of carbon-13. Consequently, peak splitting due to carbon-carbon spin-spin coupling is not observed in spectra. However, protons up to three sigma bonds away split the carbon signal according to the n+1 rule, resulting in complicated spectra.
A broadband decoupling technique is used to simplify these complex, sometimes overlapping, signals. Broadband decoupling relies on a...

Fast Decoupled and DC Powerflow

767
The fast decoupled power flow method addresses contingencies in power system operations, such as generator outages or transmission line failures. This method provides quick power flow solutions, essential for real-time system adjustments. Fast decoupled power flow algorithms simplify the Jacobian matrix by neglecting certain elements, leading to two sets of decoupled equations:

¹H NMR: Interpreting Distorted and Overlapping Signals

1.6K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

  • Inteligencia Artificial
  • Neurociencia Computacional
  • Aprendizaje Automático

Sus antecedentes:

  • Las redes neuronales de espigas (SNN) ofrecen una computación energéticamente eficiente, pero enfrentan altos costos de entrenamiento debido al procesamiento en múltiples pasos de tiempo.
  • Los métodos existentes para reducir el costo computacional de las SNN a menudo se centran en los pasos de tiempo sin abordar la redundancia de las características temporales.

  • Investigar y abordar la redundancia computacional en las dimensiones temporales de las SNN.
  • Proponer un método novedoso para el entrenamiento y despliegue eficientes de SNN.

Principales métodos:

  • El desacoplamiento diferencial temporal (TDD) transforma el cálculo de la red al dominio diferencial para separar características estáticas y dinámicas.
  • El algoritmo de aproximación de baja dispersión en el dominio diferencial basado en TDD (TDD-DDLA) cuantifica la contribución de las características temporales a las actualizaciones de gradiente para la optimización de la energía.
  • Análisis de la evolución de las características temporales basado en el criterio de sensibilidad del gradiente.

Conclusiones:

  • TDD ofrece un enfoque teóricamente fundamentado para analizar y reducir la redundancia temporal en las SNN.
  • El método permite el despliegue escalable, de bajo costo y alta precisión de SNN.
  • Este trabajo proporciona un camino para SNN más eficientes en aplicaciones prácticas.
