Abstract.With the rapid development of the global economy and the increasingly close connections among countries, maritime transport has become one of the major modes of international trade. Meanwhile, the rapid expansion of the shipping industry has drawn growing attention to pollution from ships. Among various pollutants, oily wastewater from ships has become an important issue in marine environmental protection due to its wide range of sources, complex composition, and difficulty in treatment. Based on a review of relevant domestic and international studies, this paper summarizes the sources, … Read more →

Abstract.Medical image segmentation is moving from task-specific convolutional models toward foundation models that can be adapted across organs, modalities, and clinical tasks with fewer manual labels. This transition has been accelerated by self-supervised pretraining, vision-language learning, and promptable segmentation frameworks such as the Segment Anything Model and its medical derivatives. However, the clinical value of these systems cannot be inferred from technical novelty alone. Medical images differ from natural images in dimensionality, intensity statistics, acquisition protocols, disease … Read more →

Abstract.Applying the statistical method of Simplex Centre and according to the volume ratio=2:1 of organic and inorganic matrix, 15 treatments were mixed by different proportions of four mixed-substrates including SA( Vcorn-cob: Vchicken manure=1:1), SB( Vbagasse: Vchicken manure=1:1) , SC( Vcoconut fibre: Vchicken manure=1:1)  and SD( Vpeanut shells: Vchicken manure=1:1), with inorganic medium composed of vermiculite and perlite at the volume ratio of 1:1. Taking latosol, latosol plus compound fertiliser and Vpeat:Vvermiculite:Vperlite=4:1:1 as the control groups. The hotosynthesis and chlorophyll … Read more →

Abstract.To rigorously evaluate agricultural development quality in Duerbote Mongolian Autonomous County, Heilongjiang Province, we constructed a three-dimensional indicator system spanning production efficiency, ecological environment, and socio-economic conditions. Using a hybrid weighting approach that combines the analytic hierarchy process (AHP) with the entropy weight method, we integrated these weights into a TOPSIS model to dynamically assess annual data from 2019 to 2023. The results show a sustained improvement in agricultural development quality, with the composite score rising from 0.313 in … Read more →

Abstract.With the expansion of coal mine production scale, the application scope of mechanical and electrical equipment continues to widen. Traditional mechanical and electrical equipment have shown shortcomings in terms of intelligence level, energy consumption, and safety performance. This paper discusses strategies and key technologies for upgrading and transforming mechanical and electrical equipment under the context of intelligent coal mine development, aiming to enhance their intelligence, reliability, and energy-saving and environmental protection capabilities.
