Objectives: In response to the problem of large initialization errors in specular point and geometric path computations in earth observation technology using global navigation satellite system-reflectometry (GNSS-R), an efficient new method for initializing multi-system spaceborne GNSS-R specular point estimation and geometric path computation is proposed. Methods: Based on a large number of simulated spaceborne GNSS-R reflection events, the ratio of the distance, between the projection point of the truth specular point on the direct path of the signal to the two satellites, and the geocentric angle of the reflection event under fixed orbit conditions is modeled using polynomials. Furthermore, the variation trend of these model coefficients with different GNSS satellite orbit heights is fitted to obtain a model of the variation of parameter coefficients with GNSS orbit heights, thus establishing the new initialization method. Results and Conclusions: The results of experiments based on multi-system multi-orbit GNSS-R simulation data show that the initialization accuracy of the new model is improved from hundreds or even thousands of kilometers to about 5 km compared with the existing methods, and the comparison experiments also demonstrate that the proposed method could improve the calculation efficiency of the mainstream iterative method by 79.1% in grazing observation.

In order to improve the efficiency of carbon emission in the Yellow River Basin and promote green and low-carbon development, it measured the carbon emissions efficiency of the Yellow River Basin from 2005 to 2019 by using the super efficiency SBM model. Regional differences and convergence were discussed by using Theil index, a convergence and absolute fi convergence. The influencing factors were analyzed by using spatial Dubin model. The results show that a) the carbon emission efficiency gap in the Yellow River Basin shows a W-shape evolution trend from 2005 to 2019. The carbon emission efficiency of the nine provinces in the basin is quite different and shows a lad-der-shape distribution pattern of "upstream < midstream < downs-kettle .b) The carbon emission efficiency of the Yellow River Basin does not exist a convergence, but the whole basin and the middle reaches have absolute fi convergence characteristics. Provinces with low carbon e-mission efficiency will catch up with provinces with high carbon emission efficiency at the same level of development. c )The improvement of economic development level, technological innovation level and foreign trade level have a positive impact on the carbon emission efficiency of the Yellow River Basin, while the energy consumption structure and urbanization level have a negative impact. Recommendations: vigorously develop low-carbon circular economy, promote green energy consumpe structure; strengthen technological innovation to boost efficiency, play a leading role in foreign trade; promote low-carbon transformtion of urban construction, alleviate the positive inhibit f urbanization efficiency; make full use of the positive spillover effect of space and jointly promote the carbon reduce and efficiency improvement of the basin.

In the context of the comprehensive implementation of national territory spatial planning and its use control in China, revealing the quantity and value of restricted land development rights has great theoretical and practical significance for improving the spatial governance system and solving the issue of unbalanced and insufficient development, especially regional differences. Taking Hubei Province, an ‘area with abundant ecological resources’, as the representative province, this paper firstly used the Cobb‑Douglas (C-D) production function to measure each production factor’s elasticity to the economic growth in agricultural and non‑agricultural sectors and calculate the marginal benefits of land resources in these two sectors to clarify the reality and causes of restricted land development rights. Then, in different scenarios of narrowing the economic development gap between Hubei Province and the ‘economic development advantage area’, this paper measured the quantity and value of land development rights restricted from 2009 to 2018 in this province located in the ‘area with abundant ecological resources’. The results showed that: ① Land input had an important impact on economic growth of Hubei Province. From 2009 to 2018, the economic growth of the non-agricultural sectors in Hubei Province still depended on land input, and its contribution was difficult to be replaced by other production factors. ② High opportunity cost was an important potential driving force for the transfer of land resources from agricultural sectors to non ‑ agricultural sectors. From 2009 to 2018, the marginal revenue of land in non ‑ agricultural sectors was 17.03~ 44.14 times of that in agricultural sectors in Hubei Province, and it was increasing year by year. The existence of planning regulation led to the limitation of land development rights. ③ In the context of planning regulation, it was necessary and feasible to compensate for the restricted land development rights. In different scenarios where the gap in economic development levels was reduced by 10% to 100%, the quantity of restricted land development rights in Hubei Province was between 0.53×104 ~5.35×104 hm² from 2009 to 2018, and the corresponding value accounted for a relatively low proportion of the total GDP of the area with high economic development, which was 0.02%~0.19%. It is suggested that relevant government departments should carry out system construction for compensating the restricted land development rights, quantify and realize land development rights from two aspects including the confirmation of such rights and the reform of benefit distribution mechanism, as well as gradually improve the compensation level of land development rights from the bottom‑line compensation scenario to full compensation scenario.

OBJECTIVE: The tourniquet is currently widely used in total knee arthroplasty. However, whether the application of tourniquet can increase the thickness of bone cement around the prosthesis, thereby increasing the stability and long-term survival of the prosthesis, is still unclear. This article intends to determine whether the use of tourniquet will increase the penetration thickness of bone cement through meta-analysis. METHODS: Cochrane Library, Medline, Embase, PubMed, CNKI Chinese database, Wanfang database and other databases were retrieved to search the randomized controlled trials of whether the tourniquet was used in total knee arthroplasty from inception to April 21, 2020. The test that met the standard was evaluated using Cochrane system evaluation method, and meta-analysis was performed using RevMan 5.2 software. The main outcome indicators were bone cement penetration thickness and visual analogue scale score; and the secondary outcome indicators were blood loss, blood transfusion rate, postoperative hemoglobin reduction, and complications. RESULTS: (1) Finally, 11 randomized controlled trials were included. A total of 863 patients were included, containing 432 patients with tourniquet and 431 patients without tourniquet in total knee arthroplasty. (2) Meta-analysis results showed that intraoperative use of tourniquet could effectively increase the bone cement penetration thickness around the tibial part of the prosthesis (MD=0.22, 95%CI:0.12-0.31, P < 0.000 01), but increased the incidence of complications (OR=4.02, 95%CI:2.11-7.67, P < 0.001), increased postoperative pain (MD=1.14, 95%CI:0.30-1.98, P=0.008). Reducing blood loss, blood transfusion rate and postoperative hemoglobin reduction had no significant significance (P > 0.05). CONCLUSION: The application of tourniquet in total knee arthroplasty can increase the thickness of bone cement around the tibial part of the prosthesis, and may increase the long-term survival rate of the prosthesis. However, limited to the current literature quality and sample size, the above conclusions need more high-quality research to verify. [ABSTRACT FROM AUTHOR]

The economic compensation of cultivated land protection is one of the most effective ways to provide protection measures for cultivated land and protect cultivated land resources. The reasonable division of compensation areas is an important link in the construction of an economic compensation mechanism and policy implementation. This research takes into account the dual perspectives of food security and ecological security. Taking Fujian province as a research area, the paper divides the economic compensation area of cultivated land protection in the Fujian province by using the food security method, ecological footprint, and carrying capacity calculation model. Results show that: nine cities in Fujian province can be divided into two farmland protection economic compensation payment zones (Zhangzhou city and Xiamen city), three farmland protection economic compensation zones (Quanzhou city, Sanming city, and Nanping city), and 4 balance zones (Fuzhou city, Ningde city, Putian city, and Longyan city). These results will help provide a theoretical basis for scientifically delineating the compensation area for cultivated land protection and provide a practical reference for local governments to formulate a reasonable compensation system for cultivated land protection to achieve conservation and the sustainable use of cultivated land resources.
