This paper presents a detection method of insulator stings for aerial inspection based on feature-fusion. The local sub-images strings are firstly collected from videos and tagged to establish training dataset. fusion feature is then composed by the histogram oriented gradients (HOG) binary pattern (LBP) after principal component analysis (PCA) dimension reduction separately. A model developed SVM algorithm with feature. At phase, threshold segmentation morphological operation adopted...

Existing fine-grained image recognition methods are difficult to learn complete discriminative features from low-resolution (LR) data, because the original subtle inter-class distinctions become slimmer with reduction of resolution. Besides, existing LR and general only consider restoration extraction global features, ignoring unreliable local details can be detrimental final recognition. To address above problems, we propose a multi-tasking framework, feature mining enhancement network...

Renal fibrosis, resulting from myofibroblast-mediated excessive extracellular matrix (ECM) deposition, lacks effective treatments. Novel peptide DR3penA developed by our group showed therapeutic potential for fibrotic diseases; however, its application was hindered poor stability and bioavailability. To address this unmet need, we implemented stepwise optimization of DR3penA. The conformationally restricted analogs designed via structural predictions enhanced both activity stability. Through...

Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) is an important soilborne fungal pathogen that causes the most devastating banana disease. Effectors secreted by microbes contribute to virulence on host plants in plant-microbe interactions. However, functions of Foc TR4 effectors remain largely unexplored. In this study, we characterized a novel cupin_1 domain-containing protein (FoCupin1) from TR4. Sequence analysis indicated homologous proteins FoCupin1 phytopathogenic fungi...

Abstract Leaf shape and angle are crucial components of plant architecture substantially influence photosynthetic efficiency crop productivity. In this study, we found that OsGRF1 (GROWTH-REGULATING FACTOR 1) OsGRF2 play unequally redundant roles in regulating leaf development. The osgrf1 mutant showed increased angle, mutations further enhanced effect, although the osgrf2 remained unchanged. Cell elongation on adaxial collar side caused an angle. rOsGRF1 rOsGRF2 materials, resistant to...

Background/Aims: Regional hypoxia promptly develops after trauma because of microvascular injury and increased oxygen consumption. This acute plays a positive role in early skin wound healing. One the mechanisms underlying beneficial effects on healing may be hypoxia-inducible factor-1 (HIF-1α) expression. HIF-1α affect wound-healing process through many aspects, including angiogenesis, metabolism, extra-cellular matrix synthesis remodelling. Epidermal stem cells (EpSCs) are important...

Abstract The migration of keratinocytes from wound margins plays a critical role in the re‐epithelialization skin wounds. Hypoxia occurs immediately after injury and acts as an early stimulus to initiate healing processes. Although our previous studies have revealed that hypoxia promotes keratinocyte migration, precise mechanisms involved remain unclear. Here, we found BNIP 3 expression was upregulated hypoxic keratinocytes, silencing suppressed hypoxia‐induced cell migration. Additionally,...
