At present, the commonly used composite floor of steel bar truss in prefabricated buildings has the problem that the overhanging bent steel bars in the prefabricated floor collide with the reserved steel bars in other prefabricated components, which reduces the subsequent construction efficiency. In order to solve this problem, a new type of composite floor slab with split joints was designed. The bent steel bars are distributed centrally in the middle of the stitching edge of the prefabricated bottom plate, while the ends of the bottom plate are not reinforced, which reduces the contact with the reserved steel bars of other structures.

The identification of cell types by clustering singlecell RNA sequencing (scRNA-seq) data is a fundamental step in the downstream analysis of single-cell data. However, great challenges remain owing to the inherent characteristics of scRNAseq data, including high dimensionality, high noise, and high sparsity. In this study, we propose a proximity enhanced graph convolutional sparse subspace clustering method scPEGSSC for scRNA-seq data.

Ferroelectricity can emerge in moiré patterns formed by stacking nonferroelectric monolayers, such as graphene and hexagonal boron nitride, in specific configurations. This moiré-induced ferroelectricity not only extends the scope of two-dimensional (2D) ferroelectrics but also deepens our understanding of ferroelectric mechanisms in low-dimensional systems. Here, we present a general framework for analyzing polarization in moiré superlattices by decomposing them into fundamental structural components.
