China is among the top nitrous oxide（n2O）-emitting countries, but existing national inventories do not provide full-scale emissions including both natural and anthropogenic sources. We conducted a four-decade（1980–2020） of comprehensive quantification of Chinese n2O inventory using empirical emission factor method for anthropogenic sources and two up-to-date process-based models for natural sources. Total n2O emissions peaked at 2287.4（1774.8–2799.9） Gg n2O yr-1in 2018, and agriculture-developed regions, like the East, northeast, and Central, were the top n2O-emitting regions. Agricultural n2O emissions have started to decrease after 2016 due to the decline of nitrogen fertilization applications, while, industrial and energetic sources have been dramatically increasing after 2005. n2O emissions from agriculture, industry,energy, and waste represented 49.3%, 26.4%, 17.5%, and 6.7% of the anthropogenic emissions in 2020,respectively, which revealed that it is imperative to prioritize n2O emission mitigation in agriculture,industry, and energy. natural n2O sources, dominated by forests, have been steadily growing from 317.3（290.3–344.1） Gg n2O yr-1in 1980 to 376.2（335.5–407.2） Gg n2O yr-1in 2020. Our study produces a Full-scale Annual n2O dataset in China（FAn2020）, providing emergent counting to refine the current national n2O inventories.

Variational quantum algorithms are promising methods with the greatest potential to achieve quantum advantage, widely employed in the era of noisy intermediate-scale quantum *** study presents an advanced variational hybrid algorithm(EVQlSE) that leverages both quantum and classical computing paradigms to address the solution of linear equation ***, an innovative loss function is proposed, drawing inspiration from the similarity measure between two quantum states. This function exhibits a substantial improvement in computational complexity when benchmarked against the variational quantum linear solver. Subsequently, a specialized parameterized quantum circuit structure is presented for small-scale linear systems,which exhibits powerful expressive capabilities. Through rigorous numerical analysis, the expressiveness of this circuit structure is quantitatively assessed using a variational quantum regression algorithm, and it obtained the best score compared to the others. Moreover, the expansion in system size is accompanied by an increase in the number of parameters, placing considerable strain on the training process for the algorithm. To address this challenge, an optimization strategy known as quantum parameter sharing is introduced, which proficiently minimizes parameter volume while adhering to exacting precision standards. Finally, EVQlSE is successfully implemented on a quantum computing platform provided by IBM for the resolution of large-scale problems characterized by a dimensionality of 220.

Purpose: Diet and eating habits are major risk factors for the health and the development of disease, such as, for example, metabolic disorder leading to cardiovascular pathology and cancer, decreased immunity exposing to infections. This study of the physico-chemical and nutritional properties of a soumara-based food broth was carried out with the aim of promoting the consumption of organic broth made from nere seeds (soumara). That is to alleviate certain metabolic diseases, which is a matter of food safety, and also to limit the risk for the health about the consumption of some cooking stocks on the market. Methods: Several natural ingredients such as nere seeds (soumara), ginger, black pepper, parsley and garlic were used to create a nere-based stock. All these ingredients were freeze-dried and the powder obtained was used to make the broth, regarding their physical and chemical properties. Results: The broth had a good protein content of 17.41 ± 0.367 g/100g, a lipid content of 16.80 ± 0.08 g/100g and a fiber content of 8.66 ± 0.04 g/100g. In terms of nutritional values, the broth showed good levels of calcium 184.21 ± 0.09 mg/100g, potassium 50.04 ± 1.45 mg/100g and iron and zinc. In terms of antioxidant activity, the broth also showed good antioxidant activity. Conclusion: Regarding the properties of our food broth, whose composition is based on natural ingredients, could be recommended for consumption and, its properties, could play an important role in preventing and combating certain metabolic diseases.

反腐倡廉是当前必须抓好的重大政治任务,也是不断增强人民群众幸福感的重要保障。然而,当前研究多从反腐败斗争和廉政建设两条路径来解释反腐倡廉对幸福感的影响,忽略了其一体两面的政策特征。实证研究结果发现,反腐倡廉政策框架有助于提高居民幸福感,相较于反腐框架,倡廉框架的影响更为显著。象征性代表和权力距离取向是反腐倡廉政策框架增进幸福感的内在影响因素。象征性代表在反腐倡廉政策框架增进幸福感的过程中发挥中介作用,权力距离取向能有效调节象征性代表对幸福感的影响,同时权力距离取向可以调节反腐倡廉通过象征性代表对幸福感的间接效应。
