Using panel data from 13 prefectures and cities in Xinjiang for the period 2011-2020, this study constructs an evaluation framework for high-quality agricultural development in Xinjiang from four dimensions: agriculture, environment, resources, and economy. It assesses the level of high-quality agricultural development in Xinjiang and employs cluster analysis to analyze spatial differences in high-quality agricultural development. The results indicate that the comprehensive evaluation of high-quality agricultural development in Xinjiang can be divided into three stages: a period of rapid growth (2011-2013), a period of development decline (2013-2014), and a period of stable growth (2014-2020). The overall level of high-quality agricultural development has shown an increasing trend over the years, with a distinct pattern of North Xinjiang > South Xinjiang > East Xinjiang.

Methods Data of patients with CVSS in Neurointervention Center, Beijng Tian Tan Hospital from January 2014 to August 2018 were retrospectively analyzed. The ocular characteristics of CVSS patients and ophthalmological changes after CVSS stenting were analyzed and summarized. Results Of 125 patients, 101 (80.8%) had visual impairment, including blurred vision or decreased vision, metamorphosis, transient amaurosis, visual field defect, diplopia. 65 (52.0%) patients had ocular discomfort as the first symptom and 35 (28.0%) patients had only ocular symptom. Of 115 patients (223 eyes) with initial papilledema, the median pepilledema grade was 3 (2-4) (Frisén grades). Some patients showed hemorrhage, exudation, cotton-wool spot, retinal tissue fold surrounding the disc, dilated and tortuous retinal veins, papilla pale. There was a positive relevance between papilledema grade and intracranial pressure (Kendall’s tau-b=0.271, P =0.029), and a negative relevance between papilledema grade and duration of the disease (Kendall’s tau-b=-0.261, P =0.002). 79 patients underwent venous sinus stenting, papilledema of all patients with stenting alleviated soon after operation. At 1 month after stenting, the grade of papilledema was reduced to grade 2 (1-3). At 6 months after stenting, 94.4% eyes (135/143) with initial papilledema had no edema in the disc. Conclusions Patients with binocular papilledema should consider CVSS. The fundus examination is necessary for diagnosis and follow up of CVSS and assessing intracranial pressure. Papilledema degree had a positive relevance with intracranial pressure, and a negative relevance with duration of the disease. Patients with CVSS and papilledema who are refractory for medical treatment should consider venous sinus stenting as possible as earlier to reduce papilledema and irreversible damage of optic nerve.

The change of land use type caused by human construction activities affects the quality of regional habitat. In this study, InVEST model was used to evaluate the habitat quality of Qianping Reservoir in Henan Province, and CA-Markov model was used to simulate and predict the habitat quality in 2025 and 2035. The results show that cultivated land, forest land and grassland are the main land types in the reservoir area, accounting for about 90%. From 2000 to 2020 the arable land has been shrunk and the water area is increased by 116.94% within 20 years. The average value of habitat quality in the study area is increased from 0.550 595 in 2000 to 0.557 727 in 2015, but decreased to 0.556 880 in 2020, indicating that the habitat quality of the reservoir is on the whole increasing before the construction of the reservoir, but is decreased after the construction. The evolution trend of land use and habitat quality in the study area from 2020 to 2035 is basically consistent with that from 2000 to 2020. The reduction rate of cultivated land is decreased, the expansion rate of construction land slows down significantly and the habitat quality is still in a slightly decreasing trend on the whole.

Circular monorail transportation system has been widely applied in hilly mountain areas. It is a high demand to improve the operation efficiency of static tasks in recent years. This study aims at the matching and scheduling requirements between mission points with the transport needs and transporters. The maximum full load was also considered comprehensively to determine the practice scenario of one-way goods transportation. The task was in the form of transporting cargo boxes from several loading points to a single unloading point. A mathematical model was established with the "carpooling" combined with the processing at the mission points and task assignment of transporters. The solving process of the transporter schedule was divided into two stages. In the first stage, the heuristic rule algorithms using different priorities were proposed to solve the "carpooling" combined processing with the goal of the least number of loadings of transporters. Combination algorithms included prioritization by adjacent position, task volume, and random sequence. In the second stage, a genetic algorithm based on variable neighborhood search (GA_VNS) was employed to solve the task assignment of transporters with the goal of the least number of transporter jams. GA_VNS was a hybrid intelligent algorithm with GA as a framework with the variable neighborhood search strategy, particularly with both global and local optimization. The performance of GA_VNS was compared with the standard GA, variable neighborhood search algorithm, overall matching rule, and random-restart hill-climbing algorithm. Transporting situations were simulated corresponding to three kinds of task batches. Five control experiments were carried out for each batch to improve the reliability of the experimental data. Experiments proved that the selected algorithms were superior. The designed combination algorithm with the task volume as the priority was solved fastest and was independent of the task batch. The operation time was generally between 0.3 and 0.4 s, with the lowest time cost. The feasible solution in 80% of the experiments was optimal among the three combination algorithms, and the solution advantage was concentrated in the large batch experiment, indicating more suitable for solving large-scale transportation in real time than the rest. The number of loadings in the remaining experiments was also only one unit more than the optimal solution. The solution of the assignment was also facilitated for the second stage scheduling in the validity. Therefore, the best performance was achieved in the combination algorithm with the task volume as a priority. The GA_VNS was employed to optimize the solution in multiple directions. GA_VNS significantly improved the quality of standard GA solution, and the number of transporter jams was reduced by 33.3%-100%. The higher stability was found in large-batch transporting situations, compared with the single variable neighborhood search algorithm. The probability of the minimum number of transporter jams appearing increased by 10% and 40%, but the operation time was about 10 times longer. The validity was better than other types of algorithms, such as overall matching and random-restart hill climbing. The finding can provide an approximately optimal solution to the static scheduling of the circular monorail transportation system in hilly mountain areas. [ABSTRACT FROM AUTHOR]

Coyote optimization algorithm (COA) is a swarm intelligent algorithm proposed recently, which has a unique search structure and good optimization performance. In order to improve COA further, this paper proposed a multi-strategy COA (MSCOA). Firstly, the best coyote in a group used a global best coyote-guided growth strategy to improve its social adaptation, the worst coyote in the group used the best coyote guidance reinforcement strategy to strengthen the worst coyote's search ability. Secondly, the other coyotes in the group adopted a group growth strategy that dynamically adjusted information interchange to improve information sharing degree among the coyotes in the group, and MSCOA crossed this growth strategy with an improved migration strategy to further improve search ability. Finally, MSCOA adopted a dynamic grouping strategy to reduce the manual setting of parameters and improve operability. Hybridizing the above strategies can keep better balance exploration and exploitation to maximize the performance. A large number of experimental results on complex functions from the CEC2014 test set show that MSCOA has stronger search ability, faster running speed, and higher search efficiency than COA, and has more obvious advantages over quite a few other excellent algorithms.
