Insights from a proteomic atlas of human Alzheimer's disease brain tissue

Neural Regeneration Research 2025年第3期20卷 799-800页

作者： Tomas Kavanagh Eleanor Drummond Brain and Mind centre and School of Medical Sciences University of SydneyCamperdownNSWAustralia

There is an urgent need to identify new drug targets for Alzheimer's disease(AD). While new immunotherapies show promise, clinical benefit appears low, and side effects are high. A greater understanding of the disease mechanisms driving AD is an essential factor that will facilitate the identification of new, effective drug targets.

Traffic safety helmet wear detection based on improved YOLOv5 network

引用

Optoelectronics Letters 2025年第1期21卷 35-42页

作者： GUI Dongdong SUN Bo College of Software Southeast University Quanzhou Equipment Research centre Haixi Institute Chinese Academy of Sciences

Aiming at the problem that the current traffic safety helmet detection model can't balance the accuracy of detection with the size of the model and the poor generalization of the model, a method based on improving you only look once version 5(YOLOv5) is proposed. By incorporating the lightweight Ghost Net module into the YOLOv5 backbone network, we effectively reduce the model size. The addition of the receptive fields block(RFB) module enhances feature extraction and improves the feature acquisition capability of the lightweight model. Subsequently, the high-performance lightweight convolution, GSConv, is integrated into the neck structure for further model size compression. Moreover, the baseline model's loss function is substituted with efficient insertion over union(EIoU), accelerating network convergence and enhancing detection precision. Experimental results corroborate the effectiveness of this improved algorithm in real-world traffic scenarios.

Community Needs Assessment in Relation to Urban Heat Effects: A Study in Greater Kuala Lumpur, Malaysia

Biomedical and Environmental Sciences 2018年第9期31卷 705-711页

Urban areas usually experience higher temperatures compared with their rural surroundings; this is characterized as urban heat islands （UHIs）, which are the result of environmental overheating due to anthropic activities. Urban areas,which are characterised by massive construction that reduce local vegetation coverage, are subject to the absorption of a large amount of solar radiation,which is only partially released into the atmosphere by radiation in the thermal infrared.
