Optimal transport (OT) is an effective tool for measuring discrepancies in probability distributions and histograms of features. To reduce its high computational complexity, entropy-regularized OT is proposed, which is computed through Sinkhorn algorithm and can be readily integrated into neural networks. However, each time the parameters of networks are updated, both the value and derivative of OT need to be calculated.

Antibiotic resistance in bacteria is a major global health concern. The wide spread of carbapenemases, bacterial enzymes that degrade the last-resort carbapenem antibiotics, is responsible for multidrug resistance in bacterial pathogens and has further significantly exacerbated this problem. is one of the leading nosocomial pathogens due to the acquisition and wide dissemination of carbapenem-hydrolyzing class D β-lactamases, which have dramatically diminished available therapeutic options.

, a causative agent of quartan malaria, is prevalent across tropical and subtropical regions, but global cases have been usually very rare and sporadic. However, a significant outbreak of quartan malaria caused by occurred in Khanh Vinh District, Khanh Hoa Province, Vietnam in 2023 and the outbreak persists. In this report, we present the epidemiological and clinical characteristics of this unprecedented outbreak of quartan malaria in Vietnam.

Article Synopsis
  • Context in attention-based Graph Neural Networks (GNNs) refers to the representation nodes used for graph embedding, which traditionally only includes immediate neighbors, limiting long-distance dependency capture.
  • The proposed framework improves attention-based GNNs by selecting multi-hop nodes to expand context, then employing two refinement policies to optimize computational efficiency while maintaining relevant local structures in graphs.
  • Extensive testing against 23 baseline models shows that this approach significantly enhances the performance of attention-based GNNs by effectively utilizing informative multi-hop neighbors.

Purpose: Implant-supported overdentures have been an effective treatment method for edentulous mandibles. However, the loading time after implant placement is still controversial. The purpose of this study was to evaluate the outcome of implant-supported overdentures using telescopic crowns for the treatment of edentulous patients with immediate loading protocol.
