    Abstract Introduction: With the increasing fragmentation of landscapes caused by rapid urbanisation, constructing ecological networks strengthen the connectivity between fragmented habitat patches. As the capital of China, Beijing has a rapid development, resulting in a serious landscape fragmentation, and needing an urgent demand for this study to improve the ecological network system.Methods: In this study, we choose the elevation, slope, Normalized Difference Vegetation Index and land use data of Beijing in 2020 as the data use. Morphological spatial pattern analysis (MSPA) was used to identify ecological source areas for Beijing, Minimal cumulative resistance (MCR) and gravity models were used to construct ecological network, and stepping stones to improve it.Results: The core area of Beijing had the highest proportion (96.17%) of all landscape types, forest accounting for 82.01% thereof. Ten core areas were identified as ecological source areas. Forty-five ecological corridors (8 major and 37 ordinary) were constructed. The ecological corridors are mainly concentrated in the middle and eastern regions where ecological mobility is limited. Constructing stepping stones would help uphold the region’s ecological service functions and ecosystem balance. Twenty-nine stepping stones and 32 ecological obstacles were used to create the optimised ecological network, consisting of 171.Discussion: The results provide an optimised ecological model for Beijing and a reference constructing ecological spatial networks for the sustainable development of ecological environments in high-density urban areas.

    Abstract Litchi, a succulent and perishable fruit, presents a narrow annual harvest window of under two weeks. The advent of smart agriculture has driven the adoption of visually-guided, automated litchi harvesting techniques. However, conventional approaches typically rely on laboratory-based, high-performance computing equipment, which presents challenges in terms of size, energy consumption, and practical application within litchi orchards. To address these limitations, we propose a real-time litchi detection methodology for complex environments, utilizing portable, low-energy edge computing devices. Initially, the litchi orchard imagery is collected to enhance data generalization. Subsequently, a convolutional neural network (CNN)-based single-stage detector, YOLOx, is constructed to accurately pinpoint litchi fruit locations within the images. To facilitate deployment on portable, low-energy edge devices, we employed channel pruning and layer pruning algorithms to compress the trained model, reducing its size and parameters. Additionally, the knowledge distillation technique is harnessed to fine-tune the network. Experimental findings demonstrated that our proposed method achieved a 97.1% compression rate, yielding a compact litchi detection model of a mere 6.9 MB, while maintaining 94.9% average precision and 97.2% average recall. Processing 99 frames per second (FPS), the method exhibited a 1.8-fold increase in speed compared to the unprocessed model. Consequently, our approach can be readily integrated into portable, low-computational automatic harvesting equipment, ensuring real-time, precise litchi detection within orchard settings.

    Abstract The automobile industry is the pillar industry of the national economy. The good operation of the automobile supply chain is conducive to the sustainable development of the economy and social economy. In recent years, the popular research of automotive supply chain disruption risk management has been widely of concern by both business and academic practitioners. It is observed that most of the literature has focused only on a particular journal or field; there is a distinct lack of comprehensive bibliometric review of two decades, of research on automotive supply chain disruption risk management. This paper delivers a comprehensive bibliometric analysis that provides a better understanding not previously fully evaluated by earlier studies in the field of automotive supply chain disruption risk management. We used the 866 journal article during the period between 2000 and 2022 from the WOS database as sample data. Highlights research topics and trends, key features, developments, and potential research areas for future research. The research problems we solved are as follows: (1) Over time, how does the research in the field of automotive supply chain disruption risk management progress? (2) Which research areas and trends are getting the most attention in the field of automotive supply chain disruption risk management? (i) to recognize the scholarly production; (ii) the most productive authors; (iii) the most productive organization; (iv) the most cited articles; and (v) the most productive countries. (3) What is the research direction of automotive supply chain disruption risk management in the future? Also discusses the shortcomings of literature and bibliometric analysis. These findings provide a potential road map for researchers who intend to engage in research in this field.

    Abstract Rhabdomyolysis, a potentially life-threatening syndrome, is caused by the breakdown of skeletal muscle cells and leakage of intramyocellular contents into the bloodstream. The treatment of rhabdomyolysis resulting from chronic sacrococcygeal pressure ulcers has been rarely reported. A 62-year-old man developed a high fever and dark-colored urine. For the past 30 years, he had lived with paraplegia, which led to his immobility. Physical examination showed evidence of repeated dehiscence and exudation of the wound on his sacrococcygeal region with loss of skin sensation. Upon corroboration of the physical examination findings and laboratory test results, the patient was diagnosed with rhabdomyolysis with an acute infection resulting from sacrococcygeal pressure ulcers. We first debrided the necrotic tissue and then repaired the chronic ulcer. The wound dressing was changed frequently, and antimicrobial therapy and nutritional support were included in the treatment. The fever and dark-colored urine gradually resolved postoperatively. The patient’s renal function also improved according to the typical laboratory indicators, and the size of the pressure ulcers decreased to some extent. The patient was discharged after 1 month of hospitalization. This case highlights that accurate diagnosis is critical for administration of precise treatment to paraplegic patients with progressive rhabdomyolysis.

    Abstract To effectively utilize waste mask materials in road engineering and minimize resource waste, the melt-blown fabric (MBF) of waste masks was utilized to modify the virgin bitumen. The preparation process of MBF-modified bitumen was investigated, and the physical and rheological properties of bitumen were measured. Subsequently, the blending mechanism during preparation and the dispersion morphology of the modifier were explored. Finally, the pavement performance of the mixture was investigated, and a radar chart analysis was performed to quantitatively assess the effects of MBF modification. Results suggested that the recommended preparation process of shear time, shear rate, and shear temperature was 170 °C, 4000 r/min, and 15 min, respectively. MBF enhanced the high-temperature stability of the binder and weakened the temperature susceptibility. The modification was primarily a physical process. No network structure and agglomeration formed in the bitumen after modification. The addition of MBF significantly improved the resistance of the asphalt mixture to a high-temperature deformation and water damage but harmed its low-temperature crack resistance. The comprehensive assessment results of 0% ( <semantics> f 1 </semantics> ), 1% ( <semantics> f 2 </semantics> ), 3% ( <semantics> f 3 </semantics> ), and 5% ( <semantics> f 4 </semantics> ) MBF to improve the properties of the mixture were in the following order: <semantics> f 3 > f 4 > f 2 > f 1 </semantics> , where the impact of 3% MBF was the most significant, followed by 5% and 1% MBF.

    Abstract Objective To investigate the expression changes of hsa_circ_0017650 in the human adipocyte differentiation process and adipose tissue of obese people. Methods The changes of hsa_circ_0017650 on the 0th, 1st, 3rd, 5th, 7th, 9th and 12th days of human preadipocyte differentiation were determined by RT-qPCR; Oil Red O staining was performed to observe the formation of lipid droplets on 0th, 6th, and 12th days of human preadipocyte differentiation. The mRNA levels of CCAAT enhancer-binding protein α (C/EBPα), fatty acid-binding protein 4 (FABP4/ap2), and lipoprotein lipase (LPL) in human preadipocytes were determined by RT-qPCR to identify the differentiation of human preadipocytes. A total of 125 patients who underwent appendectomy in our hospital were selected as research subjects, and were divided into obesity group (53 cases) and control group (72 cases) according to body mass index (BMI). The expression differences of hsa_circ_0017650 in retroperitoneal white adipose tissue of the two groups were compared. The Pearson’s correlation coefficient between the expression level of hsa_circ_0017650 and BMI, triacylglycerol (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) in obesity group was analyzed. Results Human preadipocytes gradually changed from spindle to oval or round, with a gradual increase in volume and an increase in fat droplets. On the 12th day of culture the levels of C / EBPα, FABP4/ap2 and LPL in human precursor adipocytes were higher than those on day 0 (PConclusions Hsa_circ_0017650 is highly expressed during human adipocyte differentiation and mainly in white adipose tissue of obese individual.It is closely related to obesity and is potential for the treatment of obese patients.

    Abstract The reliability of urban transportation systems is crucial for ensuring smooth traffic flow and minimizing disruptions caused by external factors. This study focuses on improving the stability and efficiency of transportation systems through the calibration of a refined link performance function while building upon the U.S. Bureau of Public Roads (BPR) model. To achieve this, we propose three customized algorithms—Newton’s method, Bayesian optimization, and the differential evolutionary algorithm—to calibrate the key parameters. Additionally, we conducted a sensitivity analysis to assess the influences of the model parameters on link performance. Numerical experiments conducted in Yuyao City demonstrate the applicability and efficacy of the proposed model and solution algorithms. Our results reveal that the Newton approach is notably more efficient than the Bayesian optimization algorithm and the differential evolutionary algorithm.

    Abstract The 17 sustainable development goals (SDGs) were established by the United Nations Agenda 2030 plan of action to achieve peace, prosperity, and well-being for all by 2030. SDG 3 aims to ensure healthy lives and promote well–being for all at all ages. However, oral health is not specifically mentioned and targeted in SDG 3. Numerous studies have demonstrated a connection between oral health and general health. Oral disease and the common non-communicable diseases have the co-existing modifying risk factors. In addition, oral health is associated with social, economic, cultural, and environmental problems. By the implementation of oral health care, oral health promotion, and universal health coverage, these could not only be good for oral health but also benefit for general health and well-being. Taken together, oral health is the first step to SDG 3.
