The pathogenesis of oral lichen planus (OLP) remains unclear, and microbial dysbiosis has been proposed to play a role in the OLP. Oral mucosal swabs from 77 OLP patients 76 healthy subjects were collected. bacterial community among lesion, adjacent normal mucosal, surface people analyzed by 16S sequencing. factor gender age that may affect flora distribution explored. Results indicate no significant difference microbiota between group. Compared with group, Neisseria, Haemophilus,...

Summary Network intrusion detection system (NIDS) is a key component to identify abnormal behavior of network systems and plays an important role in preventing the occurrence attacks. Although considerable number machine learning methods have been applied field detection, it still challenge for existing solutions achieve good classification performance. The traffic datasets generally redundant irrelevant features, which hinder classifiers from making more accurate predictions. Furthermore,...

Abstract Intrusion detection has become a research focus in internet information security, with deep learning algorithms playing crucial role its development. Typically, intrusion data are transformed into two-dimensional matrix by segmenting, stacking and padding them zeros for input models. However, this method consumes computational resources fails to consider the correlation between features. In paper, we transform images through visualization operations propose an entropy weighted...

Abstract With the rapid spread of Internet Vehicles (IoV) technology, vehicle network security is facing increasingly severe challenges. Intrusion detection technology has become a crucial tool for ensuring information IoV. Since traffic data IoV large and spatio-temporal characteristics, most previous studies are based on single deep learning method to extract temporal or spatial features, which does not fully features data. To address above issues, feature extraction model with selection...
