Dimensionality reduction by LPP‐L21

IET Computer Vision, 2018
Locality preserving projection (LPP) is one of the most representative linear manifold learning methods and well exploits intrinsic structure of data. However, the performance of LPP remarkably degenerate in the presence of outliers.

Synergistic Tuning of Conformational Dynamics, Electron Tunneling, and Substrate Positioning Enhances Electron Transfer in a P450 Chimera for Calcifediol Biosynthesis [PDF]

Advanced Science
Electron transfer (ET) efficiency dictates catalytic performance in multi‐domain self‐sufficient cytochrome P450s. Conventional engineering, however, predominantly focuses on localized optimization of either the active‐site pocket or linker regions ...

Non-Greedy L21-Norm Maximization for Principal Component Analysis [PDF]

IEEE Transactions on Image Processing, 2021
Principal Component Analysis (PCA) is one of the most important unsupervised methods to handle high-dimensional data. However, due to the high computational complexity of its eigen-decomposition solution, it is hard to apply PCA to the large-scale data with high dimensionality, e.g., millions of data points with millions of variables.

High L21-atomic ordering and spin-polarization in Co2MnZ (Z = Ge, Sn) Heusler thin films with low-temperature annealing process

APL Materials, 2022
Although an enhanced magnetoresistance (MR) has been observed in many Co2-based Heusler alloys by promoting their structural ordering from B2 to L21 by post-annealing at higher temperatures (Tann > 500 °C), it is desirable to search for other Heusler ...

L21 ordering of Co2FeSn thin films promoted by high-temperature annealing

AIP Advances, 2022
We report the effect of annealing on the crystalline ordering and physical properties in thin films of a nodal line semimetal candidate L21-type Co2FeSn. The Co–Fe–Sn films with a composition of Co:Fe:Sn ∼ 2:1:1 were deposited on MgO(001) substrates at a

Structural, electronic and magnetic properties of Ni2XAl (X= V, Cr, Mn, Fe, and Co) Heusler alloys: An ab initio study

Physics Open, 2020
Nickel-based Ni2XAl (X ​= ​V, Cr, Mn, Fe, and Co) Heusler alloys for both L21 and L10 crystal structures are studied by using the density functional theory. The magnetization energy and formation energy of Ni2XAl Heusler alloys are calculated.
