Study on Few-Shot Fault Diagnosis Method for Marine Fuel Systems Based on DT-SViT-KNN.

The fuel system serves as the core component of marine diesel engines, and timely and effective fault diagnosis is the prerequisite for the safe navigation of ships. To address the challenge of current data-driven fault-diagnosis-based methods, which have difficulty in feature extraction and low accuracy under small samples, this paper proposes a fault diagnosis method based on digital twin (DT), Siamese Vision Transformer (SViT), and K-Nearest Neighbor (KNN). Firstly, a diesel engine DT model is constructed by integrating the mathematical, mechanism, and three-dimensional physical models of the Medium-speed diesel engines of 6L21/31 Marine, completing the mapping from physical entity to virtual entity.

Development and Validation of a Clinicopathological-Based Nomogram to Predict the Survival Outcome of Patients with Recurrent Hepatocellular Carcinoma After Hepatectomy Who Underwent Microwave Ablation.

Aim: To develop and validate a nomogram for predicting the overall survival (OS) in patients with recurrent hepatocellular carcinoma (HCC) after hepatectomy who underwent microwave ablation (MWA).

Methods: The training cohort included 299 patients with recurrent HCCs after hepatectomy who met the Milan criteria and received MWA from April 2007 to December 2017. Baseline characteristics were collected to identify risk factors for the determination of death after MWA.

A Case-Control Study on the Correlation Between Thymidylate Synthase Gene Polymorphisms and Raltitrexed Treatment Combined with Transcatheter Arterial Chemoembolization in Hepatocellular Carcinoma Treatment.

To study the effect of single nucleotide polymorphisms (SNPs) in the thymidylate synthase () gene for their value in predicting the efficacy of raltitrexed treatment combined with transcatheter arterial chemoembolization (TACE) for the treatment of primary hepatocellular carcinoma (HCC). We conducted a genotypic analysis of the SNPs rs2790, rs8423, rs502396, rs699517, and rs1004474 in150 HCC patients who were subjected to raltitrexed treatment combined with TACE (study group) and another 150 HCC patients who were treated with doxorubicin combined with TACE (control group). After 1 year of follow-up and interventional therapy, the relationship between the SNPs and survival rate, and the prognosis for survival were analyzed.
