Digital rural construction is one of the key ways to assist rural revitalization. We characterized the spatial differentiation pattern of county-level digital rural development in the urban agglomeration around Poyang Lake from four dimensions(infrastructure, rural economy, rural governance and digitalization of rural life) based on the 2020 county-level digital rural index. Using an obstacle degree model, the dominant obstacle dimension and obstacle indicators of county-level digital rural development in the urban agglomeration around Poyang Lake were analyzed and proposed differentiated paths to promote regional digital rural development. Based on the research results, it was proposed that comprehensively strengthening the construction of digital infrastructure, increasing investment in digital finance, and unleashing the potential of regional digital consumption are important ways to promote the development of county-level digital rural areas in the urban agglomeration around Poyang Lake.

BACKGROUND: Pro-kin balance system guidance has a relatively excellent rehabilitation effect on lower extremity proprioception and trunk control in stroke patients, but its effect on knee proprioception and balance function in patients after anterior cruciate ligament reconstruction has been less reported. OBJECTIVE: To investigate the effect of rehabilitation training guided by Pro-kin balance system on proprioception and balance function of the affected knee after anterior cruciate ligament reconstruction. METHODS: A total of 84 patients who underwent anterior cruciate ligament rupture reconstruction surgery were randomly divided into observation group and control group, with 42 patients in each group. The patients in the control group received routine rehabilitation intervention after surgery, and those in the observation group were given rehabilitation training based on the guidance of Pro-kin balance system. The training in each group lasted for 8 weeks. Lysholm score and International Knee Documentation Committee score were used to evaluate the change of knee joint function before and after the intervention. Average weight-bearing strength difference, trajectory error, swing value and 30°, 45° and 60° passive angulation errors of the affected knee joint were used to evaluate the changes in the proprioception of the affected knee. The area and length of motion trajectory under open and closed eyes were used to evaluate the change of balance function. The satisfaction of patients in both groups with this rehabilitation training was investigated. RESULTS AND CONCLUSION: After training, Lysholm score and International Knee Documentation Committee score of patients in both groups were significantly higher than those before training (P < 0.01), and the above scores in the observation group were significantly higher than those in the control group (P < 0.01). After training, the average weight-bearing strength difference, trajectory error and swing value of the two groups were significantly lower than those before training (P < 0.01), and the above scores in the observation group were significantly lower than those in the control group (P < 0.01). After training, the passive angulation errors of 30°, 45° and 60° of the affected knee joints in both groups were significantly lower than those before training (P < 0.01), and those in the observation group were significantly lower than those in the control group (P < 0.05, P < 0.01). After training, the area and length of motion trajectory in both groups with eyes open were significantly smaller than those before training (P < 0.01), and the above indicators in the observation group were significantly smaller than those in the control group (P < 0.05, P < 0.01). After training, the area and length of the movement track of the patients in both groups with eyes closed were significantly smaller than those before training (P < 0.01), and the above indicators in the observation group were significantly smaller than those in the control group (P < 0.01). The satisfaction of patients in the observation group was 95, which was significantly higher than 81% in the control group (P < 0.05). To conclude, compared with the conventional rehabilitation training, the rehabilitation training based on Pro-kin balance system is more effective in improving the function, proprioception and balance function of the affected knee joints of patients undergoing anterior cruciate ligament rupture reconstruction, and the patients’ satisfaction is higher.

In actual production in the workshop, energy of machine will be consumed not only in the processing state, but also in the no-load state, and the energy consumption of machines will vary at different processing speed. In addition, with the wide application of automated guided vehicle (AGV) in workshops, its energy consumption can not be ignored, therefore the research on green scheduling of job shops considering AGV and machine speed is of great significance. Makespan is not only regarded as the efficiency indicator of workshop production, but also, to a certain extent, means the reduction indicator of machine energy consumption in no-load state and the improvement indicator of machine utilization. Based on this, the makespan and energy consumption optimization problem of the job shop considering AGV transportation and machine speed was studied. Firstly, the machine energy consumption and AGV energy consumption of job shop were analyzed, and the process constraints among AGV, job and machine were explored. And the green job shop scheduling model considering AGV transportation and machine speed was established. Then, the two-stage optimization method was adopted to optimize makespan and energy consumption of job shop. In the first stage, the machine processed at the highest speed and used an improved sparrow search algorithm to optimize makespan; in the second stage, while the makespan optimized in the first stage remained unchanged, the gap gear adjustment strategy was proposed to reduce energy consumption in job shop by reducing the machine speed of some processes to achieve optimization of the total energy consumption in job shop. Finally, the algorithms were simulated and verified using standard use cases through simulation. The experimental results show that in the first stage, the improved sparrow search algorithm can improve the quality of the population, accelerate the convergence speed of the algorithm, jump out of the local optimal solution, and obtain better makespan. In the second stage, on the basis of above makespan, the gap adjustment strategy is adopted to reduce the energy consumption, and the energy consumption can be reduced by 1.13% ~5.18% through 10 use cases. The results verify the correctness of the green scheduling model considering AGV and machine speed and the effectiveness of the improved sparrow algorithm. [ABSTRACT FROM AUTHOR]

Due to the disturbance of human activities and changes in the natural environment, the survival of red deer (Cervus elaphus xanthopygus) is facing many problems. To understand the current status of the genetic diversity of red deer and to provide a basis for assessing the health status, we evaluated the genetic diversity of red deer in the Gaogesitai-Hanwula National Nature Reserve in the southern of the Greater Khingan Mountains in Inner Mongolia using mitochondrial Cyt b and microsatellite markers. Results showed that 246 fresh feces belonged to 182 individuals. Microsatellite makers showed that the average expected heterozygosity (He) was (0. 729±0. 016), and the average observed heterozygosity (Ho ) was (0. 768±0. 029). Mitochondrial marker showed that the haplotype diversity (Hd ) was (0. 347±0. 035), and the nucleotide diversity (Pi) was (0. 248±0. 025)%. There was a large proportion of rare haplotypes (33. 33%) in this population. Overall, the population genetic diversity of red deer in this region was at a low to medium level. Therefore, to avoid the risk of genetic diversity decline in the future, it is recommended to strengthen the management and protection of red deer in this region, and there is a need to promote gene exchange with red deer individuals in neighboring regions.

To thoroughly understand growth and photosynthetic characteristics of Syringa species or varieties in a semi-arid alpine region, nine Syringa species (varieties) transplanted into the Huoshaogou basin of Xining were chosen as our experimental system. Their growth, development, and photosynthetic characteristics in the second year after transplantation were studied by field monitoring. Their adaptabilities were comprehensively evaluated based on growth and development indices and photosynthetic characteristics. No obvious differences were observed in annual increments of plant heights, crown widths, base diameters, or new branch lengths of S. oblate, S. oblate ‘Luolanzi’ and S. villosa. However, these characteristics were all significantly greater than in any of the other species. At the same time, there was an evident distinction in flower organ development among these plants. For instance, S. pekinensis var. jinyuan frequently failed to develop a flower organ, the primary branch flower rate of S. oblatecv ‘Jinye’ was low (55.0%), whereas those of the other species were all very high (100%); moreover, a significant difference in inflorescence length or width was observed among the nine species. Photosynthetic intensities or leaf PSⅡ activities in some of the nine species adapted to environmental changes. The degree of change varied among these species. Meanwhile, a significant difference in photosynthetic intensity or leaf PSⅡ activity was observed between plants occupying the same habitats. The adaptability of the nine Syringa species in the Huoshaogou basin was as follows: S. oblate＞ S. villosa＞ S. oblate ‘Luolanzi’＞ S. oblate ‘Buffon’＞ S. wolfii＞ Syringa×chinensis＞ S. oblate ‘Jinye’＞ S. meyeri＞ S. pekinensis var. jinyuan. These nine species can be divided into three categories according to growth and photosynthetic characteristics: strong, intermediate, and poor. Based on the above results, we can conclude that there are great differences in the growth performance and photosynthetic characteristics of the nine species in alpine semi-arid region. These studies suggest that these species should be applied selectively, taking into account the main functional value of proposed vegetation in alpine semi-arid areas. [ABSTRACT FROM AUTHOR]
