In recent years, green extraction of bioactive compounds from herbal medicines has generated widespread interest. Deep eutectic solvents (DES) have widely replaced traditional organic in the process. this study, efficiencies eight DESs extracting flavonoids Acanthopanax senticosus (AS) were compared. Response surface methodology (RSM) was employed to optimize independent variable including ultrasonic power, water content, solid-liquid ratio, temperature, and time. DES composed glycerol...

Wetlands have suffered from considerable degradation due to anthropogenic and natural disturbances in recent decades. Although some advancements been made, effective methods that can produce large-scale wetland maps with detailed categories are still lacking the diversity complexity of ecosystems. To address this issue, we developed a novel algorithm for types classification integrating k-fold random forest hierarchical decision tree, so named two-step algorithm. Firstly, phenology-based...

Abstract Instantaneous precipitation can often cause devastating disasters on the Earth's surface. Continuous increases in extreme around world have caused widespread concern, and it is necessary to study hourly over a large scale long time series. Using specific numbers of unique point data from 1980 2019, our research found that there are different spatial patterns regarding frequency intensity Mainland China, but clear pattern being weak west strong east China. Most events occurred June...

In 2015, the Sustainable Development Goals (SDG) replaced Millennium (MDG), providing guidance and direction for future development of countries around world. Both MDG SDG have established multiple indicators to achieve environmental sustainability. However, few studies compared changes in ecological environment during two periods. Therefore, this study selected seven major river basins China as area comprehensively assessed ecosystem service importance (ESI) within different periods based...

Surface water is an essential element that supports natural ecosystem health and human life, its losses or gains are closely related to national local sustainable development. Monitoring the spatial-temporal changes in surface can directly support reporting of progress towards development goals (SDGs) outlined by government, especially for measuring SDG 6.6.1 indicators. In our study, we focused on Baiyangdian Lake, important lake North China, explored spatiotemporal extent from 2014 2020....

Lakes have an important role in human life and the ecological environment, but they are easily affected by activity climate change, especially around urban areas. Hence, it is critical to extract water with a high precision method monitor long-term sequence dynamic changes lakes. As greatest natural lake of Beijing-Tianjin-Hebei region, Baiyangdian Lake has significant function life, socio-economic development, regional balance. This area shown large due change. The change monitoring process...

Wetlands play a critical role in the environment. With impacts of climate change and human activities, wetlands have suffered severe droughts area declined. For wetland restoration management, it is necessary to conduct comprehensive analysis loss. In this study, Xiong’an New Area was selected as study area. site, we built new method identify patterns loss integrated landscape variation elements based on seven land use maps Landsat series images from 1980s 2015. The calculated results...

Urban wetlands play an important role in sustainable urban development. A wetland city recognized by the Ramsar Convention is a with remarkable ecological performance of and can provide example for protection. Therefore identifying detailed characteristics great value to conservation wetlands. However, there no type extraction cities using multisource remote sensing data. This paper proposes framework fine- multiperiod data, which mainly includes Sentinel 1/2 Landsat 8 obtains data...

Wetland cities were proposed by the International Convention Organization for protection of urban wetlands. Few studies have performed land cover classifications internationally recognized wetland or explored what contribution classification results can make to establishment additional date. Based on Sentinel-1 and 2 data, this study used a 10-fold random forest method classify first six in China. A dataset, which had resolution 10 m included four types, was obtained area protected areas...

Abstract Purpose To assess the prognosis predictive value of semi-quantitative metabolic parameters and tumoral activity based on 123 I-meta-iodobenzylguanidine (MIBG) SPECT/CT in pretreatment neuroblastoma (NB) patients. Methods A total 50 children (25 girls, 25 boys, median age 37 months, range 1-102 months) with newly diagnosed NB, consecutively examined pretherapeutic I-MIBG between 2018 2024, were included this retrospective study. The primary tumor measured, including Tmax/Lmax,...

This study aimed to investigate the impact of Cordyceps militaris solid medium (CMM) on growth performance, immunity parameters, intestinal health and gut microbiota broilers. A total 320 male broilers were randomly allocated into 4 groups, consisting 8 replicates 10 birds per replication.

Abstract. Land surface soil moisture (SM) plays a critical role in hydrological processes and terrestrial ecosystems desertification areas. Passive microwave remote-sensing products such as the Soil Moisture Active (SMAP) satellite have been shown to monitor water well. However, coarse spatial resolution lack of full coverage these greatly limit their application areas undergoing desertification. In order overcome limitations, combination multiple machine learning methods, including linear...

Wetland carbon storage plays an essential role in the global cycle. However, recent decades, intensive human activities and rapid urbanization have reduced wetland C stocks Guangdong-Hong Kong-Macau Greater Bay Area (GBA). Long-term assessment of ecosystems GBA is needed for promoting regional sustainable development.
