Infrared small target detection algorithm based on spatial dissimilarity weighted local contrast

IET Optoelectronics, 2022
To solve the problem that the local contrast algorithm is easily influenced by the heavy clutter background or strong noise and does not fully consider the spatial neighbourhood characteristics of the small target, a spatial dissimilarity weighted local ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Wampee-YOLO: A High-Precision Detection Model for Dense Clustered Wampee in Natural Orchard Scenario

Horticulturae
Wampee (Clausena lansium) harvesting currently relies heavily on manual labor, but automation is significantly hindered by clustered fruit growth patterns, small fruit sizes, and complex orchard backgrounds, which make accurate detection highly ...

Second-Line Treatment of Non-small Cell Lung Cancer: Big Targets, Small Progress; Small Targets, Big Progress? [PDF]

Journal of Thoracic Oncology, 2006
In the current issue of the Journal of Thoracic Oncology, Noble and colleagues provide an excellent comprehensive review of systemic treatment for patients with advanced non-small cell lung cancer (NSCLC) previously treated with chemotherapy. The authors conclude that sufficient evidence exists for the routine use of either single-agent pemetrexed or ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Target Driven Adaptive Loss for Infrared Small Target Detection

2025 IEEE International Conference on Image Processing (ICIP)
We propose a target driven adaptive (TDA) loss to enhance the performance of infrared small target detection (IRSTD). Prior works have used loss functions, such as binary cross-entropy loss and IoU loss, to train segmentation models for IRSTD. Minimizing these loss functions guides models to extract pixel-level features or global image context. However,
