Accurately measuring these sediment discharges has long been a challenge. Traditional in-situ methods fall short of providing comprehensive and continuous assessments of sediment dynamics due to spatiotemporal and economic constraints. While remote sensing techniques using satellite imagery have offered valuable insights into sediment transportation and deposition, their scope is primarily restricted to observing suspended sediment loads rather than total loads. Sediment accumulation at river margins will cause gravity increases observable by the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GFO) missions. Previous efforts to observe sediment signals lacked proper corrections for various GRACE/GFO issues, including leakage of signals from surrounding land, variations in nearby ocean mass, and noise levels that typically exceed sediment signal magnitudes. In this study, we develop a new approach to obtain a satellite gravity estimate of sediment accumulation along the Amazon coast where the largest amount of sediment deposition is expected. We address limitations in previous studies using three steps: Forward modeling to suppress leakage of signal from land to oceans; adjusting ocean mass change via the sea level equation; and filtering using empirical orthogonal functions. The estimated accumulation rate of sediment on the Amazon continental shelf is approximately 1301 Mtons per year for the period June 2002 to May 2023. This estimate is slightly higher than the results from field-based studies, which fall in the range 550 to 1030 Mtons per year.","PeriodicalId":417,"journal":{"name":"Remote Sensing of Environment","volume":"1 1","pages":""},"PeriodicalIF":13.5,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143547012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, the specific surface area of CHBC reached 144 m2·g−1, which was 48 times higher than that of unactivated food waste biochar, and the adsorption of Pb(II) by CHBC was a spontaneous heat-absorption reaction, with a maximum Pb(II) adsorption capacity of 114.59 mg·g−1, which can be well described by the pseudo-second-order kinetic model and the Freundlich isothermal adsorption model. The adsorption process of Pb(II) on CHBC is dominated by chemisorption, and the adsorption mechanism includes the ion-exchange reaction of Pb(II) with Ca2+ on CHBC, the precipitation reactions with phosphate and SO32-, the complexation reactions with oxygen-containing functional groups such as –OH and C=O, the electrostatic attraction, and the Pb(II)-π interactions.

However, the low frequency of HDR hinders its application in plant genome editing. In this study, we engineered the fusion of Cas9 and a viral replication protein (Rep) as a molecular bridge to tether donor DNA in vivo, which enhances the efficiency of targeted gene insertion via the HDR pathway. This Rep-bridged knock-in (RBKI) method combines the advantages of rolling cycle replication of viral replicons and in vivo enrichment of donor DNA at the target site for HDR. Chromatin immunoprecipitation indicated that the Cas9-Rep fusion protein bound up to 66-fold more donor DNA than Cas9 did. We exemplified the RBKI method by inserting small- to middle-sized tags (33–519 bp) into 3 rice genes. Compared to Cas9, Cas9-Rep fusion increased the KI frequencies by 4–7.6-fold, and up to 72.2% of stable rice transformants carried in-frame knock-in events in the T0 generation. Whole-genome sequencing of 6 plants segregated from heterozygous KI lines indicated that the knock-in events were faithfully inherited by the progenies with neither off-target editing nor random insertions of the donor DNA fragment. Further analysis suggested that the RBKI method reduced the number of byproducts from nonhomologous end joining; however, HDR-mediated knock-in tended to accompany microhomology-mediated end joining events. Together, these findings show that the in vivo tethering of donor DNAs with Cas9-Rep is an effective strategy to increase the frequency of HDR-mediated genome editing.","PeriodicalId":221,"journal":{"name":"Plant Biotechnology Journal","volume":"35 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It demonstrates effective antiseptic activity against major periodontal pathogens P. gingivalis and F. nucleatum, with satisfying inhibition rates of 97.10 ± 0.11 % and 87.87 ± 9.16 % before and after 4 w aging, respectively. Moreover, TSM exhibits desirable adhesion ability to periodontal tissue with prolonged residence time, and reduces the local bacterial load significantly in vivo, thus effectively inhibiting the progression of periodontitis and reducing the destruction of periodontal tissue. Collectively, it is promising to serve as a periodontal topical medication, which is of great significance for controlling periodontal infection and improving the clinical outcome.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"3 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing methods struggle with reliable spatiotemporal fusion in two commonly occurring yet complex scenarios: drastic surface changes, such as those caused by natural disasters and human activities, and poor image quality, which caused by thick cloud cover, cloud shadows, haze and noise. To address these challenges, this study proposes a Reliable deep learning-based spatiotemporal Fusion framework (RealFusion), designed to blend Landsat and MODIS imagery to generate daily seamless Landsat-like imagery. ReadFusion enhances fusion reliability through several advancements: (1) integrating diverse input data with complementary information, (2) implementing task decoupled architectures, (3) developing advanced restoration and fusion networks, (4) adopting adaptive training strategy, (5) and establishing a comprehensive accuracy assessment framework. Extensive experiments, comprising 25 trials in three distinct areas, demonstrate that RealFusion outperforms four methods proposed in recent years (Object-Level Hybrid SpatioTemporal Fusion Method, OL-HSTFM; Enhanced Deep Convolutional Spatiotemporal Fusion Network, EDCSTFN; Generative Adversarial Network-based SpatioTemporal Fusion Model, GAN-STFM; and Multilevel Feature Fusion with Generative Adversarial Network, MLFF-GAN). Notably, RealFusion is the only model capable of robustly and accurately reconstructing information of areas with drastic surface changes and poor image quality in experiments. RealFusion, thus, facilitates the reliable reconstruction of high-quality images in complex scenarios, marking a meaningful advancement in spatiotemporal fusion technique.","PeriodicalId":417,"journal":{"name":"Remote Sensing of Environment","volume":"7 1","pages":""},"PeriodicalIF":13.5,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143547014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
