The coexistence of phosphorus (P) and cadmium (Cd) in river sediments poses a significant challenge for remediating these contaminants in aquatic environments, given the ongoing debates regarding their interactions. This study aimed to elucidate the impact of water-soluble phosphorus (PO43−) on the fate and transformation of sediment-associated Cd under varying conditions. The findings revealed that the impact of PO43− on the release of sediment-associated Cd depends on the presence or absence of cations such as Ca2+ and Mg2+, with Ca2+ exerting a more pronounced effect than Mg2+. In the absence of Ca2+ and Mg2+, PO43− effectively inhibits the release of sediment-associated Cd by facilitating the formation of more stable precipitates, including (Cd)3(PO4)2. Conversely, when Ca2+ and Mg2+ are present, they compete with Cd for PO43− binding sites, reducing the formation of (Cd)3(PO4)2 and indirectly enhancing the release of sediment-associated Cd. Furthermore, redox conditions play a significant role in Cd release from sediments depending on its fractions. However, this influence may be less prominent compared to that caused by PO43−. Notably, increasing sediment ageing time diminishes the enhancing effect exerted by PO43−, likely attributed to the conversion of Cd into a more stable residual fraction. This study offers further insights into the impact of PO43− on the fate and transformation of sediment-associated Cd within river sediments, necessitating simultaneous consideration of multiple variables such as cations, redox conditions, and sediment ageing. © 2024

In recent years, Fenhe River Basin (FRB) wetlands have been facing severe challenges due to climate change and human activities. It was of great significance to understand the dynamic changes of FRB wetlands and their driving factors for ecological protection. Based on the land use data, runoff, rainfall and GDP data of FRB from 1980 to 2020, the evolution characteristics and driving factors of wetland pattern in FRB were analyzed. The results showed that the wetland types in FRB mainly included paddy, reservoir, river, beach and marsh. Among them, natural wetlands accounted for 72.46 %, and constructed wetlands accounted for 27.53 %. The main types of wetlands in FRB were river, reservoirs and beach, which account for 92.26 % of the whole wetland area. However, the dominant position of reservoir patch was more obvious than the others during 1980–2020. Landscape index showed that the shape of landscape tended to be regular and became more fragmentation. The transfer between wetlands and other land use types mainly occurred in the northern and southern parts of the FRB, and the main conversion types were occurred between dry land and wetlands, grassland and wetlands. Both natural and human factors drove the evolution pattern of wetlands, but the emphases were different. Runoff had a significant effect on wetland pattern at landscape level, while rainfall had a more significant effect on wetland evolution at class level. Urbanization rate and GDP had important effects on the evolution of wetland pattern at both class and landscape levels. © 2024 The Authors

Vegetated coastal wetlands, also called blue carbon ecosystems, are significant carbon sinks that play a vital role in global climate change mitigation. Understanding the ecological mechanisms of carbon sequestration in these ecosystems is essential to effectively manage and conserve them. This review focuses on macroecological mechanisms of carbon transfer and microecological mechanisms of carbon stabilization in vegetated coastal wetland ecosystems. Macroecological mechanisms include the horizontal and vertical carbon transport coupled to plant ecophysiology and community diversity, while microecological mechanisms include processes related to soil organic matter dynamics, such as decomposition, stabilization, and mineralization. key scientific issues surrounding these mechanisms include transformation between carbon sink and source, stabilization mechanisms of organic carbon, and environmental effects at multiple time scales. A comprehensive research framework is also presented, which integrates spatial-temporal pattern, macroecological mechanism, microecological mechanism, and ecological engineering. Addressing these key scientific questions within the proposed framework can provide valuable insights into the significant role of biodiversity in blue carbon ecosystems, as well as significant implications for management and conservation of vegetated coastal wetlands under global climate changes. © 2025 Old City Publishing, Inc.

Due to years of anthropogenic impact, many water bodies have sediment rich in phosphorus. The redox potential (Eh) is crucial for determining the adsorption or release of phosphorus from sediments. This study examines the effects of Eh variations under aerobic and anaerobic conditions on the phosphorus release dynamics in different water bodies (rivers, lakes, and reservoirs). Findings include: (1) In sediment-overlying water systems, Eh shows an inverse trend with pH, also affecting metal concentrations;(2) Under anaerobic conditions, sediments release more phosphorus, with iron being a key factor in Eh-regulated phosphorus release;(3) The phosphorus adsorption capacity of lake and reservoir sediments is sensitive to changes between aerobic and anaerobic environments. To prevent algal blooms, stricter regulatory measures are recommended during water level fluctuations in lakes and reservoirs. © 2024, The Authors. All rights reserved.

In the era of media information explosion, there is an urgent need for a fast and reliable image quality assessment (IQA) model to improve the actual application effect of images. To this end, we propose the multiple information measurement fusion metric (MMFM), which innovatively combines two types of information measures (IMs), i.e., local IM and global IM, using only a small number of references for IQA. First, inspired by the free energy theory, we combine 2-dimensional autoregressive model with sparse random sampling method as an inference engine on an input image to generate its associated predicted image. Second, by the inspiration of pixel-wise measurement, we obtain the local IM by calculating the information entropy of the residual error between the input image and its corresponding predicted one. Third, motivated by the histogram-based measurement, we acquire the global IM by computing the two kinds of divergences between the input image and its predicted one. Fourth, we systematically fuse three components, independently including one distance of local IM between the reference and corrupted images and two distances of global IMs between the reference and corrupted images, based on a linear function to derive the final IQA result. The results of experiment on the most popular LIVE database show that our designed algorithm with only one number used as few reference has achieved well performance as compared with several mainstream IQA models. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

The magnetic coupler is the core component of the wireless charging system. Its magnetic parameters have a significant effect on transmission performance. However, the current analytical models used for multi-objective optimization design are inadequate with poor calculation accuracy, leading to challenges in achieving comprehensive multi-objective optimal. This paper proposes an efficient fitness function modeling method for multi-objective optimization based on the deep belief network (DBN), enhancing both the design accuracy and optimization speed. Firstly, a three-dimensional magnetic circuit model is developed to consider the coil, magnetic core, and aluminum plate. Secondly, a loss correlation model of the magnetic coupler is established. Thirdly, the deep belief network (DBN) regression is utilized to obtain an accurate fitness characterization function. Finally, the fractional particle swarm optimization (FPSO) is applied to achieve the Pareto optimal solution of the magnetic coupler’s design parameters. In this work, the WPTI rectangular coil is taken as an illustrative example. An optimized design with a coupling coefficient of 0.23, transmission efficiency of 97.5%, and a weight of 9.6 kg is selected for experimental verification. The results demonstrate that the predicted values match the measurements with an error less than 5%.

Unfavorable environmental cues severely affect crop productivity resulting in significant economic losses to farmers. In plants, multiple regulatory genes, such as the WRKY transcription factor (TF) family, modulate the expression of defense genes. However, the role of the pineapple WRKY genes is poorly understood. Here, we studied the pineapple WRKY gene, AcWRKY28, by generating AcWRKY28 over-expressing transgenic pineapple plants. Overexpression of AcWRKY28 enhanced the salt stress resistance in transgenic pineapple lines. Comparative transcriptome analysis of transgenic and wild-type pineapple plants showed that “plant-pathogen interaction” pathway genes, including 9calcium-dependent protein kinases (CPKs), were up-regulated in AcWRKY28 over-expressing plants. Furthermore, chromatin immunoprecipitation and yeast one-hybrid assays revealed AcCPK12, AcCPK3, AcCPK8, AcCPK1, and AcCPK15 as direct targets of AcWRKY28. Consistently, the study of AcCPK12 over-expressing Arabidopsis lines showed that AcCPK12 enhances salt, drought, and disease resistance. This study shows that AcWRKY28 plays a crucial role in promoting salt stress resistance by activating the expression of AcCPK genes.
