Cultivated land fragmentation is often considered to reduce agricultural productivity, leading to threatening food security. The pattern and drivers of cultivated land fragmentation can be expected to serve as an important prerequisite for scientific management. Taking Jiangsu Province as the study area, this study aims to assess the cultivated land fragmentation at the county level from four dimensions, including PD (patch density), AWMSI (area-weighted mean shape index), SHDI-S (Shannon's diversity index of area), and COHESION (patch cohesion index). A systematic analysis was made on the clustering features of cultivated land fragmentation in different dimensions using the K-means. MGWR (multiscale geography weighted regression) model was applied to explore the driving factors of cultivated land fragmentation in each county from five dimensions: topographic site, soil properties, urbanization, utilization intensity, and protection strength. The results showed that there were north-south differences in the cultivated land, where the PD and AWMSI were higher in the south than those in the north, the SHDI-S was higher in the north than in the south, and the COHESION was higher in the west. The four dimensions of the county-level cropland fineness index showed three types of clustering: Type A and Type B counties were located in the southern part of the province, both of which shared high patch density, irregular shape, and high area diversity. Among them, the Type A counties were higher connectivity of cultivated land than Type B; Type C counties shared lower patch density, regular shape, low area diversity, and high cropland connectivity, which were distributed mainly in the central and northern parts of the province. In addition, spatial heterogeneity was observed in the driving factors of cultivated land fragmentation in different types of regions. Differentiated fragmentation management should be adopted for the different regions. Among them, cultivated land fragmentation in the southern counties and districts (Type A and Type B) was mainly driven by natural factors (elevation, slope, and soil capacity). There were the more complex factors in the central and northern counties (Type C), including cropland allocation and urbanization. Cultivated land in the Type A counties exhibited a high density and irregular shape of patches, but a high degree of connectivity, which was a greater potential for management. Some considerations were given to promote the merging of adjacent cultivated land for large-scale production when the soil properties were similar in the topographic conditions. A low degree of contiguous cultivated land was observed in Type B counties, indicating the more complex driving factors are more difficult to manage. More attention should be paid to protecting the existing cultivated land for future urbanization. Cultivated land in Type C counties shared a low density and regular shape of patches, with the large cultivated land and continuous distribution. Cultivated land in Type C counties was the most affected by the topographic slope and protection. The central and northern regions were mainly plains with flat terrain and arable land, indicating the low potential for management. However, some attention should still be paid to regulating the use of cultivated land. The finding can provide a strong reference to managing the cultivated land fragmentation in Jiangsu Province. The cropland fine fragmentation model can also be optimized to develop the sustainable use of cropland. [ABSTRACT FROM AUTHOR]

This study addresses issues such as low efficiency in maintaining a constant temperature, uneven temperature distribution, uneven mixture, uneven reaction, and large deviations in experimental data observed in the ethyl acetate saponification reaction and iodine clock reaction. To address these problems, improvements are made in two aspects: the reaction vessel and the mixing method of reactants. The use of a jacketed beaker paired with a reaction flask as the reaction vessel and a multi-site magnetic stirrer for rapid mixing of the reactants is proposed. This improvement ensures a uniform and stable temperature in the solution, enhances the uniform dispersion and rapid reaction of the reactants, and enables accurate measurements of solution conductivity and the time for color change. The obtained data provides accurate values for reaction order, rate constant, and activation energy. [ABSTRACT FROM AUTHOR]

In order to solve the problem that the daily rehabilitation training of cardiovascular patients depends on directing by health care professions in rehabilitation centre, during assessing and correcting the movements system about cardiovascular patients independent rehabilitation training at home, this paper proposed an action assessment method for cardiovascular patients' rehabilitation training based on key points of the human skeleton (ASRT-PHS). Firstly, this paper constructed a dataset for rehabilitation training actions using a camera and data augmentation in accordance with the specified rehabilitation training specification for cardiovascular patients. Secondly, this paper employed a deep learning-based detector and pose estimator to capture human body positions and extract key points of the human skeleton, respectively, and then input the results into a convolutional neural network for action recognition. Thirdly, by calculating joint angle thresholds, joint distance ratio and assessing standard motions, this paper constructed a motion segmentation model based on joint distance ratios and an action assessment model based on action joint angle thresholds. This paper investigated the optimal combination of ASRT-PHS by assessing its performance with various joint angle thresholds and action recognition approaches. The results show that ASRT-PHS achieves an average action recognition, segmentation and assessment accuracy of 92.78%, 77.6% and 87%, respectively. Furthermore, case tests about the true cardiovascular patients show that the average accuracy of the prototype system is 71.3%, which provides a feasible intelligent auxiliary system for patients autonomous rehabilitation training at home.

Granular grain can be stored into the warehouse in food industry. The high loading efficiency is often required to optimize the land use for the effective grain preservation. The crucial warehouse mode has emerged in the regions with limited land resources. The diverse grain varieties can be stored to promote the sustainable development. Currently, the granular grain warehouse normally employs a load-bearing system that constituted by a reinforced concrete frame structure. The vertical gravity load of the grain is supported by the well-beam floors and large-section frame columns, while the lateral pressure exerted by the grain is directly absorbed by reinforced concrete horizontal tie-up beams integrated within the warehouse walls. The structural integrity of granular grain warehouses can also depend on the dynamic lateral pressure exerted by the storage material on the warehouse wall during seismic events. In this study, a scaled-down 1:25 three-story warehouse was designed and then produced to explore the effect of granular grains on the dynamic lateral pressure. Shaking table tests were carried out to simulate the varying ground vibration levels under three seismic waves. The data was collected on the acceleration and the lateral pressure that exerted on its walls. Analysed the seismic response characteristics of the storage material. Furthermore, the overpressure coefficient was obtained from the patterns of dynamic lateral pressure on the walls. The dynamic lateral pressure on the warehouse walls was also calculated. Acorrelation analysis was conducted between the height of warehouse and the timing of the peak moment, when the dynamic lateral pressure was exerted on the warehouse walls. Specifically, there was a noticeable lag in the occurrence of this peak moment, as the height of the building increased. Moreover, the peak moment of dynamic lateral pressure on the warehouse wall was consistently lagged behind that of acceleration on the same wall, particularly with the elevation of the height. The dynamic lateral pressure on the warehouse walls escalated progressively with each ascending floor. In the given floor, this dynamic lateral pressure incrementally intensified along the vertical extent of the warehouse walls. Each floor was found with an average increase of approximately 29% per floor. The dynamic lateral pressure exerted on the upper and middle sections of the warehouse walls was 2.5 and 1.4 times greater than that on the lower sections within the same floor. Consequently, the structural design of granular grain warehouses should consider these variations across different floor levels. The overpressure coefficient of the warehouse wall increased with the elevation of the floor, indicating a higher overall overpressure at upper levels. Within a single floor, the overpressure coefficient peaks at the upper section of the warehouse wall, with the middle and lower sections exhibiting lower and closer. Specifically, the maximum overpressure coefficients were 2.9, 3.4, and 4.1, respectively, for the first, second, and third floors of the warehouse walls. The overpressure on the warehouse walls was of significant concern, when subjected to seismic activity. It is very necessary to consider the influence of the dynamic lateral pressure on the warehouse wall across various floors. The seismic response of the storage materials can be used to elucidate the distribution pattern of dynamic lateral pressure. The overpressure on the warehouse walls can be assessed to calculate the lateral pressure on these walls. The findings can offer a strong reference for the warehouses of granular grains under seismic conditions. [ABSTRACT FROM AUTHOR]

Accurate and rapid detection of building changes is of great significance to identify latent areas along transmission lines. With the development and progress of satellite remote sensing technology, building change detection based on high resolution remote sensing image has become a research hotspot. A Gaussian probability model integrating features such as shadow, building index, texture and shape was proposed to realize initial extraction of buildings at the pixel level. Based on this, object-level change detection of buildings was realized by combining multi-scale segmentation results. Finally, the spatial superposition analysis was carried out on the extraction results of object-level buildings in the front and back phases, and the superposition results were divided into three categories: building addition, building demolition and building reconstruction. Remote sensing images with different resolutions were used in the research area and the verification area respectively for experiments and verification. The results show that the proposed method achieves practical results and detection accuracy under different scales and image resolutions, and can provide good technical support for the detection of building changes along the transmission line.
