Dissolved oxygen is an important index to measure water quality. The accurate prediction of dissolved oxygen can provide reference for scientific management and protection of water environment. Considering that dissolved oxygen was affected by many external factors and the data had strong nonlinear and non-stationary characteristics, the DA-CNN-BiLSTM dissolved oxygen prediction model was proposed. The CNN layer was used to extract local features of data. Spatial attention focused on features that had a higher impact on prediction outcomes. BiLSTM mined the attribute relationships of the input sequence. Temporal attention layer captured the time dependence of different moments. The model was applied to the dissolved oxygen prediction of three water quality monitoring stations in Minjiang River, Fujian Province. By comparing with the baseline model, it shows that the DA-CNN-BiLSTM model has a better prediction of DO concentration compared with the baseline model. The predicted value of the model is closer to the measured value and the DO prediction performance is optimal. The prediction performance of the model has been improved after adding the spatial attention mechanism. [ABSTRACT FROM AUTHOR]

(1) Background--The big food view broadens the boundary of food, meets people's demand for high-quality life, and responds to the realistic problem of food security in China. Forest ecological products take realizing people's urgent needs for a better life as value orientation, and contain ecological value, economic value and social value. The realization of the value of forest ecological products is becoming a powerful driving force for practicing the big food concept, steadily promoting the green and high-quality development of the under-forest economy, and realizing the revitalization of rural ecology. The academic research on the value realization of forest ecological products mainly focuses on the value accounting system and ecological compensation mechanism, etc. (2) Methods--This paper constructed a complete set of "value chain-supply chain-industrial chain" from the perspective of big food view, corresponding to the driving mechanism of "power mechanism-support carrierrealization form" respectively. The value, value transformation and value excavation of forest ecological products were sorted out from the perspectives of multi-functionality, multi-supply and green innovation of big food view, and the methods to realize the value of forest ecological products were discussed. (3) Results--First, the paper expounds the basic logic of the value realization of forest ecological products from two aspects of history and theory. From the historical perspective, the big food view reflects people's awareness of food acquisition, food utilization and the importance of forests, guiding forest ecological products to realize the value from a new perspective. From the theoretical perspective, the big food view indicates that we should view the realization of the value of forest ecological products from the perspective of food supply, human development and harmonious coexistence between man and nature. Second, the historical and theoretical logic of big food view are not separate from each other, but complement each other. It shows that it is feasible and important to explore the paths to realize the value of forest ecological products under the interaction of the historical promotion and theoretical support of big food view. Third, from the perspectives of domestic and overseas, food security, people's well-being and green development, the problems existing in the process of realizing the value of forest ecological products are summarized, such as the lack of the big food concept, the neglect of forest functions and the value realization mechanism of forest ecological products is still in the primary stage, etc. (4) Conclusions and Discussions--The big food view emphasizes the all-round, multi-mode, wide-range and high-level development of food resources in the whole land resources, making food categories more diversified and containing multiple values such as food security, aesthetics, ecology, education and leisure, which is the scientific concept of the realization of green and high-quality development. The realization of the value of forest ecological products is an important way to practice the big food concept and promote the production of food resources to be more green, high-quality and sustainable. In order to improve the value realization mechanism of forest ecological products, this paper sorts out the value chain of forest ecological products, improves the supply chain of forest ecological products, and constructs the industrial chain of forest ecological products. However, there are still many innovative and effective ways to realize the value of forest ecological products, which need to be further explored: First, promote the value realization of forest ecological products from the perspective of digital technology. Second, promote the value realization of forest ecological products from the perspective of common prosperity. Third, promote the value realization of forest ecological products from the perspective of forest property right reform. [ABSTRACT FROM AUTHOR]

India believes that the tension between China and the United States will continue, exerting impact on shaping a multi-polar world and bringing a series of global consequences, which is both a challenge and an opportunity for India itself. In response, India has taken a series of measures, including working with the US to counter China’s rise through “Issue-based Alignment” and “Asymmetric Accommodation”; reshaping the partnership with neighboring countries to advocate the “India way” and weaken the influence of the Belt and Road Initiative; enhancing cooperation with the US in the Indian Ocean to shape the “Indo-Pacific” concept to prevent China’s domination of the region; claiming to support the global free trade system, but emulating the US’ protectionism against China. Compared with its active geostrategic response, India is ill-prepared for the global economic turmoil triggered by the competition between China and the US. In the future, India’s strategy of “working with the US and countering China” will not be fundamentally changed. However, India’s response to the long-term impact of the China-US competition remains tentative, given the changes in major-country relations, the competition of new technologies and the uncertainty of the economic reform in India. While being alert to the geo-strategic interactions between India and the US, China should focus on the big picture, properly manage differences, and seek cooperation with India in the context of India’s economic and technological policy uncertainties and the common challenges faced by the two sides against the backdrop of COVID-19.

Objective: To investigate the effect of Atorvastatin combined with irbesartan on renal function and micro inflammatory state in elderly patients with early diabetic nephropathy(DN). Methods: 84 elderly patients with DN who were treated in the department of nephrology of our hospital from April 2016 to February 2017, and the patients were divided into the control group and the observation group according to the random number table method, 42 cases in each group. The control group was treated with irbesartan, and the observation group was treated with Atorvastatin combined with irbesartan.Urinary albumin excretion rate(UAER) and the levels of serum creatinine(Scr), blood urea nitrogen(BUN), β2 microglobulin(β2-MG), interleukin-1(IL-1), interleukin-10(IL-10), tumor necrosis factor-α(TNF-α) of patients in two groups were compared, and the adverse reactions in the two groups were compared between the two groups. Results: After treatment, the levels of UAER, Scr, BUN, β2-MG of patients in the two groups were decreased, and UAER, Scr, BUN, β2-MG in the observation group were lower than that in the control group(P<0.05). After treatment, the levels of serum IL-1 and TNF-α were decreased in the two groups, and the level of IL-10 was increased(P<0.05), after treatment, the levels of serum IL-1 and TNF-α in the observation group were lower than that in the control group, and the level of IL-10 in the observation group was higher than that in the control group(P<0.05). The incidence of adverse reactions in the two groups was not statistically significant(P>0.05). Conclusion: Atorvastatin combined with irbesartan is effective in the treatment of elderly patients with early DN, it can significantly improve the patient’s renal function, reduce the micro inflammatory state, and the safety is good, which is worthy of clinical application.
