In the context of carbon neutrality, the paper uses Super Efficiency Data Envelopment Analysis (DEA) to evaluate the level of regional energy efficiency in China, then selects Theil index to analyze the difference and change of regional energy efficiency. The results are as follows: (1) The overall level of energy efficiency in China is relatively low, and the average efficiency level from 2007 to 2019 is 0.568. Among them, Beijing is the highest, at 1.261, and Xinjiang is the lowest, at only 0.205. The energy efficiency of the eastern region is the highest in China: the average is 0.812. The central region is lower than the national average, with the value of 0.534. The lowest energy efficiency is in the western region, which is only 0.349. It can be seen that there are significant differences in regional energy efficiency, and from west to east has increased. (2) The Theil coefficient increased before 2012 and began to show a downward trend in 2013. The difference in the eastern region maintained the smallest downward trend among the three regions. The difference in the central region fluctuated and increased before 2011, and dropped sharply after 2012. In the western region, the coefficient is relatively stable and has not changed significantly. (3) Differences within and between regions in China show an overall downward trend. From the perspective of contribution rate, the difference between regions contributes the most to the overall difference. • We use super-efficiency DEA to measure China's regional energy efficiency. • We use Theil Index to illustrate regional differences in energy efficiency. • We have reached a conclusion that can provide a theoretical reference for policy making. • We compared the magnitude and trend of energy efficiency in various regions.

This investigation delves into the utilization of tremolite, a rare mineral, as a pottery temper for cooking vessels of the late Neolithic lower Yangtze Liangzhu culture. Raman spectroscopy analysis of 165 mineral-tempered pottery sherds from the Dazemiao site revealed that tremolite was the predominant tempering material for tripods (ding), whereas a mixture of feldspar and quartz was used for open-topped vats (da-kou-gang). SEM images indicate that the tremolite temper exhibits relatively coarse fiber structure, corresponding to one of the nephrite materials used for the Liangzhu jade. It is suggested that the Liangzhu miners reallocated materials according to nephrite quality, formulating different product lines, including different types of jade objects and pottery temper. Additionally, the utilization of tremolite temper persisted throughout the entire Liangzhu culture. The presence of tremolite-tempered pottery in regions without indigenous tremolite mines necessitated robust logistical networks for the transportation of these bulky materials. The tremolite temper not only reconfirms the strong 'jade culture' of Liangzhu, but also provides evidence of extensive socio-economic exchanges between different geographical regions on the Yangtze River delta. • Potters used tremolite temper in Liangzhu culture (5300-4300 BP), China. • Tremolite temper was widely used in the cooking vessel – tripod (Ding). • Nephrite jade craftsmanship influenced the use of tremolite temper. • A riverine logistical network encouraged the circulation of tremolite. • A complex polity made efforts to integrate transport networks.

The use of microwave radiation data collected by lunar orbiters to infer the lunar brightness-temperature (TB) distribution is of great importance to lunar scientific exploration. The TB data acquired by China's Chang'E-2 passive microwave radiometer (MRM) is one of the basic materials for lunar temperature mapping. Core issues of lunar microwave TB mapping include data fitting at different latitudes, outlier removal, and integrated spatial interpolation considering influencing factors. We applied a third-order Fourier function to fit the lunar TB data, which effectively removes outliers considering the fitting characteristic and three-sigma rule (FCTSR). Because the lunar surface temperature is influenced by a variety of factors such as topography and albedo, we then built a multi-factor co-kriging interpolation method to perform lunar TB mapping accurately. The cross-validation shows that, in terms of the mean-absolute-error and root-mean-square-error, the multi-factor co-kriging interpolation improves the mapping accuracy by 30%–60% compared to inverse distance interpolation and ordinary kriging interpolation. The analysis shows that topography and albedo are the most important factors influencing the lunar TB, and the TB maps at 37 GHz reveal cold spots that can be considered as younger craters. It is concluded that the proposed data fitting, denoising and spatial interpolation methods significantly improve the lunar TB mapping. The results and scientific data can also provide a basic energy map for lunar roving path planning and subsequent lunar exploration. • TB outliers were effectively removed using the fitting characteristics and three-sigma rule. • A multi-factor co-kriging method was developed to produce accurate lunar TB maps. • The co-kriging improves accuracy by 30%–60% compared to IDW and ordinary kriging. • The TB maps at 37 GHz reveal cold spots that can be identified as younger craters.

Applying pesticides can result in emissions of volatile organic compounds (VOCs), but little is known about VOC emission characteristics and the quantities in particular regions. We investigated the use of pesticides in China based on a large-scale survey of 330 counties in 31 provinces and evaluated the national pesticide VOC emission potentials based on thermogravimetric analysis of 1930 commercial pesticides. The results showed that herbicides were the most extensively used pesticide category in China, accounting for 43.47%; emulsifiable concentrate (EC), suspension concentrate, and wettable powder were the dominant pesticide formulations, with proportions of 26.75%, 17.68%, and 17.31%, respectively. The VOC emission potential coefficient (EP) of the liquid formulations was higher than the solid formulations, and the maximum mean EP was 45.59% for EC and the minimum was 0.76% for WP. Among 437 high-VOC pesticide products used in China, EC accounted for 83.52%, and 16.93% of those contained abamectin. The total VOC emissions derived from commercial pesticides in China were 280 kt (kilotons) in 2018, and 65.35% of the contribution was derived from EC. Shandong, Hunan, and Henan were the three provinces with the highest pesticide VOC emissions (>21 kt/y). The emission rate of VOCs from pesticides was 24.80 t/d in China, which was higher than in San Joaquin Valley, California. These findings suggest that some comprehensive measures (e.g., perfecting pesticide management policy, strict supervision for pesticide production and use, and strengthening pesticide reduction publicity) should be taken to reduce VOC emissions from pesticide applications. [Display omitted] • Emulsifiable concentrate (EC) is the most widely used formulation in China. • Liquid formulations have higher VOC emission potentials than solid formulations. • Abamectin is the most prevalent active ingredient in high-VOC pesticide products. • EC contributed the highest (65.35%) pesticide VOC emission quantity in China. • Pesticide VOC emission rate of China is obviously higher than in San Joaquin Valley.

Cryptosporidium spp. and Enterocytozoon bieneusi are common and important enteric parasites that can infect humans and animals, causing diarrhoea and systemic diseases. The objectives of the present study were to examine the prevalence and genetic variations of Cryptosporidium and E. bieneusi in pigs transferred from northeastern China to Ningbo city in Zhejiang Province. Cryptosporidium spp. was detected in 0.9% (2/216) of these samples and belonged to the zoonotic species Cryptosporidium parvum. A high E. bieneusi infection rate (25.0%, 54/216) was observed in this study, with 7 possible novel ITS genotypes (JLNB-1 to JLNB-7) and 10 known genotypes (EbpA, CM11, H, CM6, pigEBITS1, EbpC, CS-4, pigEBITS5, CHS5, and Henan-Ⅳ) identified, and zoonotic EbpA was the dominant genotype. Genotypes H and pigEBITS1 were reported for the first time in pigs in China. Phylogenetic analysis indicated that all the genotypes found in these samples belonged to zoonotic group 1. These findings indicated the potential threat of Cryptosporidium and E. bieneusi to humans or the environment during cross-regional transportation. An effective management control system should be built to avoid parasitic transmission as well as other animal diseases while travelling across different regions. In further studies, attention should be given to the transmission routes and the role of pigs as a potential source of human Cryptosporidium and E. bieneusi infections in China. • A high E. bieneusi infection rate with 7 possible novel ITS genotypes and 10 known genotypes belonged to zoonotic group 1. • Cryptosporidium parvum was identified in pigs. • Parasitic transmission during animals transportation across regions.
