Cadmium(Cd)pollution poses a serious threat to plant growth and yield.Nanomaterials have shown great application potential for alleviation of Cd toxicity to plants.In this study,we applied graphitic carbon nitride nanosheets(g-C_(3)N_(4)NSs)for alleviation of Cd-toxicity to soybean(Glycine max L.).The g-C_(3)N_(4)NSs supplementation significantly improved plant growth and reduced oxidative damage in the Cd-toxicated soybean seedlings through hydroponic culture.Particularly,the g-C_(3)N_(4)NSs dynamically regulated the root cell wall(RCW)components by increasing pectin content and modifying its demethylation via enhancing pectin methylesterase(PME)activity,therefore greatly enhanced stronger RCW-Cd retention(up to 82.8%)and reduced Cd migration to the shoot.Additionally,the g-C_(3)N_(4)NSs reversed the Cd-induced chlorosis,increased photosynthetic efficiency because of enhancement in F_v/F_mration,Y(Ⅱ)and sugars content.These results provide new insights into the alleviation of Cd toxicity to plants by g-C_(3)N_(4)NSs,and shed light on the application of low-cost and environmental-friendly carbon-based NMs for alleviating heavy metal toxicity to plants.

While progress has been made in information source localization,it has overlooked the prevalent friend and adversarial relationships in social networks.This paper addresses this gap by focusing on source localization in signed network models.Leveraging the topological characteristics of signed networks and transforming the propagation probability into effective distance,we propose an optimization method for observer selection.Additionally,by using the reverse propagation algorithm we present a method for information source localization in signed networks.Extensive experimental results demonstrate that a higher proportion of positive edges within signed networks contributes to more favorable source localization,and the higher the ratio of propagation rates between positive and negative edges,the more accurate the source localization becomes.Interestingly,this aligns with our observation that,in reality,the number of friends tends to be greater than the number of adversaries,and the likelihood of information propagation among friends is often higher than among adversaries.In addition,the source located at the periphery of the network is not easy to identify.Furthermore,our proposed observer selection method based on effective distance achieves higher operational efficiency and exhibits higher accuracy in information source localization,compared with three strategies for observer selection based on the classical full-order neighbor coverage.

The pollutant control performance of exhaust hoods plays a crucial role in the indoor air quality and energy consumption of ventilation systems in industrial buildings.To better understand the impact of local ventilation on the industrial indoor environment,this paper presents a literature review of exhaust hood performance and its improvement technologies.To create an index for evaluating the performance of exhaust hoods,the capture velocity,capture efficiency,flow ratio of pollutant emissions and exhaust airflow and energy consumption are first introduced.A number of factors affecting exhaust hood performance are assessed such as hood type,hood opening size,exhaust rate,installation distance,pollution source emission and environmental disturbance.Compared to structural improvement methods,the use of active airflow is a more effective way to improve the exhaust hood performance.The most commonly used methods for determining the exhaust rate are the controlled speed method and the flow ratio method.The use of an exhaust hood with an appropriate exhaust rate and jet parameters(for an active air-assisted hood)can effectively improve the pollutant control performance and reduce the energy consumption that would be wasted on the redundant exhaust rate.With more information focused on exhaust hood performance,this work suggests more effective strategies for improving indoor air quality and reducing energy consumption in industrial buildings.

BACKGROUND Individuals with refractory ascites in the context of liver cirrhosis typically face an adverse prognosis.The transjugular intrahepatic portosystemic shunt(TIPS)is an efficacious intervention,but there is a lack of reliable tools for postoperative pro-gnosis assessment.Previously utilized clinical biochemical markers,such as the serum albumin concentration(Alb),sodium(Na+)concentration,and serum creatinine(Scr),have limited predictive value.Therefore,the quest for novel,specific biomarkers to evaluate the post-TIPS prognosis in patients with liver cirrhosis and refractory ascites holds significant practical importance.A retrospective analysis was conducted on 75 patients with liver cirrhosis and refractory ascites who underwent TIPS at our institution from August 2019 to August 2021.These patients were followed up regularly for two years,and the death toll was meticulously documented.The patients were allocated into a survival group(n=45 patients)or a deceased group(n=30 patients)based on their prognosis status.The clinical data of the two groups were collected,and Child-Pugh scores and MELD scores were calculated for analysis.Spearman correlation analysis was carried out to evaluate the correlation of prognosis with Child-Pugh grade,MELD score,and Cys C level.Additionally,a multiple-factor analysis utilizing the Cox proportional hazard model was used to identify independent risk factors affecting the post-TIPS prognosis of patients with liver cirrhosis and refractory ascites.The receiver operating characteristic curve(ROC)ascertained the predictive value of the Cys C concen-tration,Child-Pugh grade,and MELD score for the prognosis of liver cirrhosis with refractory ascites in post-TIPS patients.RESULTS During a 2-year follow-up period,among 75 patients with liver cirrhosis and refractory ascites who underwent TIPS treatment,30 patients(40.00%)passed away.The deceased cohort exhibited heightened aspartate aminotrans-ferase,alanine aminotransferase,total bilirubin,Scr,prothrombin time,Cys C,internationa

Phase engineering is an efficient strategy for enhancing the kinetics of electrocatalytic reactions.Herein,phase engineering was employed to prepare high‐performance phosphorous‐doped biphase(1T/2H)MoS_(2)(P‐BMS)nanoflakes for hydrogen evolution reaction(HER).The doping of MoS_(2)with P atoms modifies its electronic structure and optimizes its electrocatalytic reaction kinetics,which significantly enhances its electrical conductivity and structural stability,which are verified by various characterization tools,including X‐ray photoelectron spectroscopy,high‐resolution transmission electron microscopy,X‐ray absorption near‐edge spectroscopy,and extended X‐ray absorption fine structure.Moreover,the hierarchically formed flakes of P‐BMS provide numerous catalytic surface‐active sites,which remarkably enhance its HER activity.The optimized P‐BMS electrocatalysts exhibit low overpotentials(60 and 72 mV at 10 mA cm^(−2))in H_(2)SO_(4)(0.5 M)and KOH(1.0 M),respectively.The mechanism of improving the HER activity of the material was systematically studied using density functional theory calculations and various electrochemical characterization techniques.This study has shown that phase engineering is a promising strategy for enhancing the H*adsorption of metal sulfides.

The insufficient active sites and slow interfacial charge trans-fer of photocatalysts restrict the efficiency of CO_(2) photoreduction.The synchronized modulation of the above key issues is demanding and chal-lenging.Herein,strain-induced strategy is developed to construct the Bi–O-bonded interface in Cu porphyrin-based monoatomic layer(PML-Cu)and Bi_(12)O_(17)Br_(2)(BOB),which triggers the surface interface dual polarization of PML-Cu/BOB(PBOB).In this multi-step polarization,the built-in electric field formed between the interfaces induces the electron transfer from con-duction band(CB)of BOB to CB of PML-Cu and suppresses its reverse migration.Moreover,the surface polarization of PML-Cu further promotes the electron converge in Cu atoms.The introduction of PML-Cu endows a high density of dispersed Cu active sites on the surface of PBOB,significantly promoting the adsorption and activation of CO_(2) and CO desorption.The conversion rate of CO_(2) photoreduction to CO for PBOB can reach 584.3μmol g-1,which is 7.83 times higher than BOB and 20.01 times than PML-Cu.This work offers valuable insights into multi-step polarization regulation and active site design for catalysts.

There are many studies on sales forecasting in e-commerce,most of which focus on how to forecast sales volume with related e-commerce operation data.In this paper,a deep learning method named FS-LSTM was proposed,which combines long short-term memory(LSTM)and feature selection mechanism to forecast the sales volume.The indicators with most contributions by the extreme gradient boosting(XGBoost)model are selected as the input features of LSTM model.FS-LSTM method can get less mean average error(MAE)and mean squared error(MSE)in the forecasting of e-commerce sales volume,comparing with the LSTM model without feature selection.The results show that the FS-LSTM can improve the performance of original LSTM for forecasting the sales volume.

Herein,a novel dual-emission fluorescence sensor array of carbonized polymer dots(CPDs)-Cu^(2+)has been proposed,in which CPDs were prepared by one-pot hydrothermal method and Cu^(2+)acting as a quencher was combined with CPDs by electrostatic interaction.Four negatively charged glycosaminoglycans(GAGs)bearing different hydrophilic groups showed variable binding affinities towards CPDs-Cu^(2+).Upon reacting with these GAGs,the different fluorescence response signals of CPDs-Cu^(2+)can be further differentiated by principal component analysis(PCA).The CPDs-Cu^(2+)sensor array,not only allows the identification of four similarly structured GAGs,but also realizes the discrimination of different concentrations of the same GAGs and their mixtures.Remarkably,the identification of GAGs in biological fluids can also be achieved using our proposed single-component sensor array,validating its application potential.This new strategy avoids multiple sensing probes,broadens the application of tongue-mimic sensor arrays and provides a viable idea for the development of single component sensing platforms.

Chemical precipitation is a widely applied approach for a liquid fraction of digestate(LFD)of agricultural waste but its large-scale application requires low-cost and efficient precipitating agents and novel process design.This study evaluated novel approach for the efficient removal of contaminants from the LFD using fly ash-based chemical precipitation,followed by filtration and CO_(2) mineralization.The technical feasibility of this approach was evaluated using pH and electrical conductivity(EC),and removal efficiencies of total phosphorus(TP),chemical oxygen demand(COD)and heavy metals during the treatment.The fly ash used in this study showed a promising performance as a chemical precipitation agent for COD and TP removal from the treated LFD involving complex effects of precipitation and adsorption.CO_(2) bubbling after fly ash-based chemical precipitation provided further COD and TP removal by carbonation reactions between CO_(2) and the excessive alkaline minerals in fly ash.Although addition of fly ash to untreated LFD increased pH from 8.3 to 12.9 and EC from 7.01 to 13.7 mS·cm^(−1),CO_(2) bubbling helped neutralize the treated LFD and reduce the EC,and concentrations of toxic ions by carbonation reactions.The fly ash-based chemical precipitation and CO_(2) mineralization had>93%COD and>98%TP removal efficiencies,and resulted in an EC of<2 mS·cm^(−1) and a neutral pH in the treated LFD,as well as the high purity calcite product.
