A new approximate inverse preconditioner based on the Vaidya’s maximum spanning tree for matrix equation AXB = C [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2019 We propose a new preconditioned global conjugate gradient (PGL-CG) method for the solution of matrix equation AXB = C, where A and B are sparse Stieltjes matrices. The preconditioner is based on the support graph preconditioners.

An efficient genomic prediction method without the direct inverse of the genomic relationship matrix
Frontiers in Plant Science, 2022 GBLUP, the most widely used genomic prediction (GP) method, consumes large and increasing amounts of computational resources as the training population size increases due to the inverse of the genomic relationship matrix (GRM).

Advanced Functional Materials, EarlyView.Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM

Advanced Functional Materials, EarlyView.We report a versatile nanoclay gel carrier platform that enhances the osteogenic efficacy of demineralized bone matrix (DBM) by integrating nanoclay‐based self‐assembly with cell‐derived exosome mimetics loaded with noggin‐targeting miR‐200c. This design amplifies BMP signaling, thereby promoting DBM‐mediated osteogenesis and offering a promising ...

International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the
