Multi-Object Detection and Classification in Construction Sites Based on YOLOv5

Xintao Liang Tianqi Jiang Qiang Fu Qingyan Wang

A thorough analysis of the framework structure of the YOLO algorithm is conducted, and based on the YOLOv5 algorithm, rapid detection and classification of extracted features are implemented. Addressing the issue of multi-object detection and classification in engineering sites, this study utilizes the YOLOv5 algorithm for object detection in engineering scenarios, constructs the ResNet50 network, and achieves training and recognition of categories for engineering vehicles, whether washed or unwashed. Additionally, the YOLOv5 algorithm is employed to detect whether construction personnel are wearing safety helmets and reflective clothing, enabling fast and accurate entity detection and classification at construction sites.

Curriculum Planning for Undergraduates Majoring in Preschool Education at Higher Education Teachers College:Researching Analysis on Sichuan Kindergarten Teachers and Key Teachers of Chengdu Secondary Speicialized Schools

Journal of Sichuan College of Education (2009)

Qingyan Wang

Preschool education has developed dramatically and preschool teachers' training system has changed greatly since the very beginning of this century.Currently,preschool education college is shoudering the responsibility of training high-quality teachers for secondary specialized schools and the vital task of educating qualified teaching and nursing teachers for kindergartens and nurseries.In order to adjust the regular preschool-education college courses to meet the requirements and demands of educating qualified teacher,a survey is carried out on kindergarten headmasters in Sichuan province and the backbone teachers at Chengdu's secondary specialized schools.The result of the survey has provided constructive data and information for curriculum planning of preschool education's undergraduate courses.

Process Optimization of Salidroside with Cellulase Auxiliary Ultrasonic-Assisted Extraction from Rhodiola Cretinii by Response Surface Methodology

IOP Conference Series Earth and Environmental Science (2020)

Baihui Wang Qingyan Wang Zhaoying Lu Junxia Liu Fengming Dou

Abstract The cellulase auxiliary ultrasonic-assisted extraction process of salidroside from Rhodiola cretinii was optimized by response surface methodology. The extraction content of salidroside was measured by HPLC, On the basis of single factor experiment, extraction time, quantity of cellulase, extraction temperature and ethanol concentrations were selected as independent variables, and the extraction content of salidroside was selected as response value, Box-Behnken design was adopted and optimized extraction process in this experiment, the optimum extraction conditions were confirmed. The results showed that the optimu extraction conditions were as follows: 29 min, 0.18% cellulose, 43°C, 39% ethanol concentration, the extraction content of salidroside was 4.49 mg/g. Through the verified tests, the content of salidroside was 4.39 mg/g after cellulase was added, the content of salidroside without cellulase was 0.48 mg/g. The response surface analysis can predict the experimental results well, and this experiment can provide a more reasonable and effective method for extracting salidroside from R. cretinii .

Overexpression of lncRNA NEAT1 mitigates multidrug resistance by inhibiting ABCG2 in leukemia

Oncology Letters (2016)

Caihua Gao Jianying Zhang Qingyan Wang Chunhua Ren

Leukemia is a heterogeneous clonal disorder in which early hematopoietic cells fail to differentiate and do not undergo programmed cell death or apoptosis. Less than one-third of adult patients with leukemia are managed using current therapies due to the emergence of multidrug resistance (MDR), emphasizing the need for newer and more robust approaches. Recent reports have suggested that long non-coding RNAs (lncRNAs) contribute to selective gene expression and, hence, could be manipulated effectively to halt the progression of cancer. However, little is known regarding the role of lncRNA in leukemia. Nuclear paraspeckle assembly transcript 1 (NEAT1) is a nuclear-restricted lncRNA involved in the pathogenesis of certain types of cancer. Deregulated expression of NEAT1 has been reported in a number of human malignancies, including leukemia and other solid tumors. The present study aimed to characterize the role of NEAT1 in the regulation of MDR in leukemia. Using reverse transcription-quantitative polymerase chain reaction, it was demonstrated that NEAT1 messenger RNA (mRNA) expression levels were significantly downregulated in leukemia patient samples compared with those from healthy donors. Furthermore, NEAT1 mRNA expression was repressed in a number of leukemia cell lines, including K562, THP-1, HL-60 and Jurkat cells, compared with peripheral white blood control cells, consistent with the expression observed in patients with leukemia. In addition, the transfection of a NEAT1 overexpression plasmid into K562 and THP-1 leukemia cell lines alleviated MDR induced by cytotoxic agents, such as Alisertib and Bortezomib, through inhibition of ATP-binding cassette G2. Although more robust studies are warranted, the current findings provide the basis for the use of NEAT1 as a novel promising target in the treatment of leukemia.

The Construction and Communication Strategy of Chinese City Animation IP in the New Media Era-- Taking "Qin Feng" as an Example

Frontiers in Art Research (2022)

Qingyan Wang Gaofeng Mi

With the advent of the new media era, the public puts higher requirements on the sensory experience of the city image. Animation IP uses anthropomorphic design methods to vividly, accurately, and intuitively show the development process and unique regional cultural symbols of a city, consolidating the core competitiveness of the city. On the one hand, it further promotes the innovation and inheritance of local culture in the new era; on the other hand, it establishes a recyclable cultural industry ecosystem to promote the transformation, upgrading, and scientific development of the urban cultural tourism industry. This paper focuses on Shaanxi animation IP resources "Qin Feng" and discusses it from three aspects: culture, cross-border operation, and new media communication, in order to provide a reference innovation path for animation development and urban empowerment.
