Abstract
The Front Cover shows Wiener skewing in sedimentation velocity boundary of highly concentrated macromolecular solutions. The transient refractive index gradient produces an optical aberration that can be recognized by the displacement of the Rayleigh interference optical baseline features associated with the migrating refractive index gradient. The red lines represent two select baseline blips with best-fit translation and slope. Global analysis of the translation versus slope data reveals the magnitude of Wiener skewing, which then can be modeled in the sedimentation analysis. More information can be found in the Research Article by Sumit K. Chaturvedi and Peter Schuck (DOI: 10.1002/cmtd.202400035).
前盖显示了高浓度大分子溶液沉降速度边界的维纳偏斜。瞬态折射率梯度产生光学像差，可以通过与迁移折射率梯度相关的瑞利干涉光学基线特征的位移来识别。红线表示两个选择的基线点，具有最适合的平移和斜率。平移与坡度数据的整体分析揭示了维纳偏斜的大小，然后可以在沉降分析中建模。更多信息可以在Sumit K. Chaturvedi和Peter Schuck的研究文章中找到（DOI: 10.1002/cmtd.202400035）。
