¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)01:20

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

1.0K
When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

False Memories01:18

False Memories

83
False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors.
One primary source of false memories is misattribution, where individuals incorrectly associate external information...

Double Resonance Techniques: Overview

197
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

  • 统计方法学的统计方法.
  • 生物信息学是一种生物信息学.
  • 基因组学就是基因组学.

背景情况:

  • 同时控制真实发现比例 (TDP) 在高维数据分析中至关重要.
  • 现有的TDP控制方法往往缺乏灵活性,可以根据用户的专业知识来优先考虑特定的功能集.
  • 将统计能力定位为生物相关或预先规定的特征集仍然是一个挑战.

研究的目的:

  • 提出一种新的统计程序,允许用户将统计能力集中在预先指定的"焦点集"上.
