我们使用应用于各种分子表示的深度学习技术预测分子的质谱图。 使用定制的库匹配任务评估性能行为。 在此任务中,我们通过将分子光谱与标记光谱库进行匹配来识别分子。 作为基线,该文库包含NIST主文库中的所有分子,其模仿了实验化学家当前使用的行为。 为了测试我们的预测,我们用模型中的光谱预测替换了库的某些部分。 下...

Ion intensity increases by color intensity and from blue to red. Note that very low intensity ions are not visible because the dynamic range of ion intensities detected spans three orders of magnitude; C, Magnification of the area shaded in yellow and labeled “C” in panel B. High mass ...
(gravi-) sensitive ion channels and cascades of ubiquitous second messengers10. According to multiple studies, signal amplification, gravity sensing and graviorientation are closely connected to cytoskeletal elements11,12,13in plants. Single cells may be able to sense changes in gravity and convert ...
