Summary: This study evaluated the feasibility of pilot-scale microalgae cultivation in real wastewater and proposed a continuous cultivation mode of attached microalgae (CCMA). The study found that microalgae have strong purification ability in wastewater, but a high nitrogen-to-phosphorus ratio led to long-term phosphorus shortage. Fluctuation in wastewater quality and quantity disrupted the balance of microalgae growth and wash-out, while the aggregation of microalgae at the bottom inhibited sustainable wastewater purification.

Summary: The stochastic block model is a widely studied network model for community detection, but fitting its likelihood function on large-scale networks is challenging. In this article, the authors propose a novel likelihood based approach that decouples row and column labels, enabling fast alternating maximization. The method is computationally efficient and has provable convergence guarantee, and it is shown to provide consistent estimates of communities in a stochastic block model.

Summary: In this study, four novel derivatives of chitosan oligosaccharide (COS) were synthesized by grafting pyridine-4-aldehyde Schiff bases onto chloracetyl chitosan oligosaccharide (CACS). The structural characterization was conducted using FTIR and NMR. The COS derivatives showed better antioxidant and antibacterial activities compared to COS and CACS, which may be attributed to the positive charge of these derivatives. Among them, derivative BPCACS with the highest degree of substitution exhibited the best bioactivity with high scavenging rate and inhibition diameter.

Summary: Urban expansion has exacerbated the heat-island effect, but urban lakes can significantly alleviate this effect. The temperature of the lake is the main factor influencing the cooling efficiency, while the lake area and the distance to the city center are secondary factors. Lakes around the urban area have limited ability to absorb the high surface temperature caused by the heat-island effect, resulting in lower cooling efficiency compared to lakes in the main urban area.

Summary: The interannual sea surface temperature trend in the East China Sea (ECS-Kuroshio) differs significantly from that of the ECS-shelf region. Observational temperature data from 1982 to 2014 indicate that the upstream ECS-Kuroshio shows an opposite temperature trend to the downstream, creating a horizontal dipole structure. The variability in upwelling in the upstream ECS-Kuroshio is the main factor influencing this distinct temperature trend, which can be transported downstream through horizontal advections.

Summary: Payment channels are a promising solution to improve scalability in decentralized ledgers by enabling micropayments without involving the blockchain. This paper introduces a novel off-chain system called channel hub, which shortens the routing path for payment networks. Compared to existing payment hubs, channel hub is more efficient and lightweight as it connects already constructed payment channels within the network. The proposed protocol, Boros, ensures secure off-chain cross-channel transfers and is demonstrated with a proof-of-concept prototype.

Summary: For human safety, efficient removal of formaldehyde in indoor environments is crucial. A metal-organic framework-based single-atom iron catalyst (Fe-SA) is proposed as a potential catalyst for formaldehyde oxidation. Through density functional theory (DFT) calculation, the adsorption characteristic and reaction path of Fe-SA with different coordination environments were explored. Fe-SA with 5-nitrogen coordination (Fe-SA-N-5-C) was selected and tested, showing a formaldehyde removal efficiency of 85.8% at 25 degrees C and 75% relative humidity, surpassing current data. Moisture was found to enhance catalytic oxidation of formaldehyde, indicating the practical applicability and stability of Fe-SA-N-5-C.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
