Abstract

With rising global temperatures, wildfires frequently occur worldwide during the summer season. The timely detection of these fires, based on unmanned aerial vehicle (UAV) images, can significantly reduce the damage they cause. Existing Convolutional Neural Network (CNN)-based fire detection methods usually use multiple convolutional layers to enhance the receptive fields, but this compromises real-time performance. This paper proposes a novel real-time semantic segmentation network called FireFormer, combining the strengths of CNNs and Transformers to detect fires. An agile ResNet18 as the encoding component tailored to fulfill the efficient fire segmentation is adopted here, and a Forest Fire Transformer Block (FFTB) rooted in the Transformer architecture is proposed as the decoding mechanism. Additionally, to accurately detect and segment small fire spots, we have developed a novel Feature Refinement Network (FRN) to enhance fire segmentation accuracy. The experimental results demonstrate that our proposed FireFormer achieves state-of-the-art performance on the publicly available forest fire dataset FLAME—specifically, with an impressive 73.13% IoU and 84.48% F1 Score.

Abstract

Rationale: Primary extracranial meningiomas are rare outside the head and neck region. Patient concerns: A 44-year-old female patient had chest pain for more than 1 year. Diagnoses: Preoperative chest computed tomography (CT) scan revealed a nodule in the right lower lobe, 1.8 cm in diameter. Tumor tissues were examined by immunohistochemistry for vimentin and S-100. Interventions: Histopathologically, the tumor was characterized by whorled nests of spindle-shaped cells accompanied by psammoma bodies. Immunohistochemistry demonstrated tumor cell positivity for vimentin and S-100. This case was diagnosed as a primary pulmonary meningioma. The tumor was removed by a thoracoscopic pulmonary wedge resection. Outcomes: Postoperative cranial and spinal CT scan did not show any intracranial or spinal mass. No recurrence of the tumor was reported at the time of writing up this case report. Lessons: A primary pulmonary meningioma should be considered in the differential diagnosis workup of pulmonary nodules.

Abstract

Based on field research data of farmers in Zhejiang Province, the authors analyzed factors influencing farmers’ participation in forest farmers cooperatives (hereafter referred to as FFCs) by the binary logistic regression model. Results show that understanding of farmers about cooperatives has a great influence on their behavior of participation in FFCs. Besides, educational level of householders and existing member scale of cooperatives also have significant influence on farmers’ behavior of participation in cooperatives. Therefore, it is required to strengthen propaganda of cooperatives, deepen their understanding of cooperatives; cultivate new high quality farmers to provide talents for development of cooperatives; establish incentive mechanism to encourage farmers to participate in cooperatives.
