Unique Dimerization Topology and Countercation Binding Modes in 12-Metallacrown-4 Compounds
(Wiley-VCH Verlap & Co. KGaA, 2022-11-17)
Seven dimeric metallacrowns (MC) based on Ln[12-MCM(III)N(shi)-4], where LnIII=Dy, Ho, Yb, or Y, MIII=Mn or Ga, and shi3− is salicylhydroximate, have been synthesized and characterized by single-crystal X-ray diffraction, ...
High-dimensional principal component analysis with heterogeneous missingness
(Academic PressWiley Periodicals, Inc., 2022-11)
We study the problem of high-dimensional Principal Component Analysis (PCA) with missing observations. In a simple, homogeneous observation model, we show that an existing observed-proportion weighted (OPW) estimator of ...
