Viruses, as the most common organisms in the natural world, have significant impacts on both the environment and human society. Metagenomic sequencing of the virome can provide comprehensive information about viral sequences within microbial communities. Therefore, it is crucial to classify viral and host sequences from metagenomic data. Currently, the analysis of viral sequences heavily relies on one-hot encoded text data, which poses challenges due to its large volume and difficulty in extracting deep features. In this study, we propose a graph-based deep learning approach called GCN-LSTM for the classification of viral sequences in metagenomic data. GCN-LSTM utilizes a graph encoding technique to represent viral and host sequences, and employs graph convolution to extract features. Furthermore, it employs an LSTM neural network with self-attention mechanism to achieve the classification of viral and host sequences. Experimental results demonstrate that the performance of the proposed model improves with increasing sequence length, and outperforms the commonly used DeepVirFinder method.

Trace data provides opportunities to study self-regulated learning (SRL) processes as they unfold. However, raw trace data must be translated into meaningful SRL constructs to enable analysis. This typically involves developing a pattern dictionary that maps trace sequences to SRL processes, and a trace parser to implement the mappings. While much attention focuses on the pattern dictionary, trace parsing methodology remains under-investigated. This study explores how trace parsers affect extracted processes and downstream analysis. Four methods were compared: Disconnected, Connected, Lookahead, and Synonym Matching. Statistical analysis of medians and process mining networks showed parsing choices significantly impacted SRL process identification and sequencing. Disconnected parsing isolated metacognitive processes while Connected approaches showed greater connectivity between meta-cognitive and cognitive events. Furthermore, Connected methods provided process maps more aligned with cyclical theoretical models of SRL. The results demonstrate trace parser design critically affects the validity of extracted SRL processes, with implications for SRL measurement in learning analytics.

Corrosion of reinforcing bars is a major factor affecting the durability of reinforced concrete structures. The volume of corroded reinforcement expands and the protective layer gradually cracks, which in turn reduces the serviceability of the structure. In this study, a fibre optic intelligent corrosion monitoring device based on magnetic sensing is investigated. A new type of magnetic probe is designed for sensing the corrosion of steel reinforcement, and strain sensing is carried out by utilizing high elasticity diaphragm and fibre optic grating structure. A finite element method is utilized to simulate the sensitivity and linearity of the device under different magnetic forces. The experimental results show that the sensor has good mechanical response effect and the fibre optic diaphragm stress sensing structure has good linearity, which can achieve longterm high-precision non-destructive monitoring of rebar corrosion.

A key issue in the research of intelligent prosthetics is the verification and analysis of the proposed prosthetic motion planning and control methods. In this paper, it is proposed that using a humanoid walking robot as the subject can effectively test the interaction dynamics between the prosthesis and the human body. This method also avoids the risk of injury to amputee patients when participating in the test before the control method is mature. Specifically, the anthropomorphic walking of bipedal walking robots is first realized, and a testbed that fully simulates the straight leg walking is obtained. The right leg (below the thigh) of the bipedal robot is then replaced with an intelligent prosthesis. When testing the planning and control methods of intelligent prosthetics, prosthetic controllers run independently. The bipedal walking robot, except for the part below the right thigh, normally performs the "humanoid motion controller". Effective intelligent prosthetic control methods will make the prosthesis-"human" coupling system produce smooth walking movements, while ineffective intelligent prosthetic control will cause the coupling system to fall due to strong interference.
