An unsupervised multi-view contrastive learning framework with attention-based reranking strategy for entity alignment.

Entity alignment is a crucial task in knowledge graphs, aiming to match corresponding entities from different knowledge graphs. Due to the scarcity of pre-aligned entities in real-world scenarios, research focused on unsupervised entity alignment has become more popular. However, current unsupervised entity alignment methods suffer from a lack of informative entity guidance, hindering their ability to accurately predict challenging entities with similar names and structures.

Contrastive cross-domain sequential recommendation via emphasized intention features.

The objective of cross-domain sequential recommendation is to forecast upcoming interactions by leveraging past interactions across diverse domains. Most methods aim to utilize single-domain and cross-domain information as much as possible for personalized preference extraction and effective integration. However, on one hand, most models ignore that cross-domain information is composed of multiple single-domains when generating representations.

Two-dimensional few-layered PC as a promising photocatalyst for overall water splitting.

Recently, 2D carbon phosphides (PCs) have attracted much attention due to their superior electronic and photovoltaic properties suitable for potential applications in field effect transistors and photodetectors. In this work, we systematically investigate the stability, electronic properties, optical absorption and photocatalytic water splitting performance of few-layered PC3 by using the first principles calculation method. Numerical results indicate that both monolayered and bilayered PC3 can serve as efficient photocatalysts for overall water splitting due to their high stability, moderate band gaps, suitable band edge positions, anisotropic high carrier mobilities and strong capacity of solar absorption.

CN/BlueP van der Waals hetero-structure: an efficient photocatalytic water splitting 2D material.

Constructing van der Waals (vdW) hetero-structures is an effective and feasible method to enhance two-dimensional (2D) materials with desired properties and to extend the application of the original materials. In this work, we establish a CN/BlueP vdW hetero-structure and explore its photocatalytic water splitting performance by investigating the electronic structure, band edge alignment, charge transfer, optical absorption and strain response based on the density functional theory (DFT) method. Numerical results indicate that the CN/BlueP hetero-structure possesses a proper direct bandgap and intrinsic type-II band alignment, which are beneficial to the space separation of photo-generated electron-hole pairs.

[Hidden blood loss after lumbar spinal stenosis operation].

Objective: To determine the total blood loss and hidden blood loss associated with surgery for lumbar spinal stenosis and to identify risk factors for blood loss.

Methods: From September 2002 to July 2006, the clinical data from 138 patients with lumbar spinal stenosis undergoing initial operation were analysed prospectively. There were 44 males and 94 females, aging 56-78 years (mean 66.

Monitoring island flap for fibular graft in 30 patients with long bone defects.

Objective: To study the effect of vascularized fibular graft on large defects of long bones and the monitoring method for the vascular status of the grafted fibula.

Methods: From March 1988 to February 1998, 30 patients with long bone defects over 6 cm in length received vascularized fibular graft including a monitoring island flap in our department to monitor the blood circulation of the fibulae.

Results: Monitoring island abnormalities were indicated in 6 flaps, which accurately gave the alarm of the circulation crisis of the fibular graft.
