Abstract Triggered by the pioneering research on graphene, family of two-dimensional layered materials (2DLMs) has been investigated for more than a decade, and appealing functionalities have demonstrated. However, there are still challenges inhibiting high-quality growth circuit-level integration, results from previous studies far complying with industrial standards. Here, we overcome these utilizing machine-learning (ML) algorithms to evaluate key process parameters that impact electrical...

Biotransformation of rare earth oxide (REO) nanoparticles on biological membranes may trigger a series adverse health effects in biosystems. However, the physicochemical mechanism complicated biotransformation behavior remains elusive. By investigating distinctly different two typical REOs (Gd2O3 and CeO2) erythrocyte membranes, we demonstrate that dephosphorylation by stripping phosphate from phospholipids correlates highly with membrane destructive REOs. Density functional theory...
Multi-label text classification (MLTC) aims to assign appropriate labels each document from a given set. Prior research has acknowledged the significance of label information, but its utilization remains insufficient. Existing approaches often focus on either correlation or textual semantics, without fully leveraging information contained within labels. In this paper, we propose multi-perspective contrastive model (MPCM) with an attention mechanism integrate and documents, utilizing methods...
