Masking and Demasking Agents

Masking and Demasking Agents

EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

背景情况:

从纸质记录中转录的灰度电心电图 (ECG) 经常受到严重的噪音.
这种噪音使准确的波形解释变得复杂,并影响下游的诊断任务.
现有的无声化方法可能无法充分解决转录ECG的独特噪声特征.

研究的目的:

开发一个强大的基于生成对抗网络 (GAN) 的框架,以拒绝灰度ECG.
创建一种有效的方法,用于构建高质量的ECG无证数据集.
为了提高心电图波形恢复和随后的心脏病诊断的准确性.

主要方法:

提出了一种基于GANs的ECG波形无声化方法 (生成对抗网络心电图无声化),同时训练生成器和歧视器进行端到端无声化.
使用GANs开发了一种ECG背景噪声生成技术,以创建用于数据集构建的多样化,现实的噪声模式.
使用波形相似度指标和对心脏病诊断准确度的影响来评估denoising性能.

主要成果:

提出的基于GANs的方法在ECG无声化方面取得了卓越的表现,子相似系数为92.72%和IOU为86.58%.
报道的数据集显著提高了心脏病诊断的准确性,达到89%和82.19%的准确性,超过了基线方法.
