China launched its first spaceborne Precipitation Measurement Radar(PMR)on the FY-3G satellite in April 2023.To achieve the scientific goal of measuring the three-dimensional precipitation structure,evaluating the quantitative measurement ability of the PMR is critical.China operates more than 250 weather radars over the mainland.Consistency of the spaceborne radar with ground-based radars will enhance precipitation measurement ability,especially over oceans and mountains where observations are sparse.Additionally,the spaceborne radar can be used to evaluate the spatial and temporal homogeneity of the ground-based radar network.This paper focuses on comparing the PMR onboard the FY-3G satellite with S-band China New Generation Weather Radars(CINRADs).A comparison algorithm between the PMR and CINRADs has been developed,incorporating detailed quality control,attenuation correction,data optimization,spatiotemporal matching,non-uniform beam filling constraint,uniformity constraint,and frequency correction.The matched data in typical months of four seasons were selected to carry out the comparison.The data consistency between the PMR and CINRADs was analyzed.The correlation coefficient is 0.87,the deviation is 0.89 dB,and the standard deviation is 2.50 dB,based on 98226 matching samples.The results show the radar reflectivity of the PMR is quite comparable to that of the CINRADs,demonstrating that the PMR data quality is satisfactory and can be used to verify and correct data consistency among multiple ground-based radars.This work also paves the way for data fusion and joint application of satellite and ground radars in the future. 展开更多

Increasing greenhouse gas(GHG)emissions,such as methane(CH4),nitrous oxide(N2O),and carbon dioxide(CO2),from agricultural practices and land use have increased concerns about global warming.Accurate quantification of the GHG using gas sensors is essential for effective management and sustainable agricultural practices.The objective of this study was to make an analytical comparison of the performance of various sensing materials for CH4-,N2O-,and CO2-based sensors in terms of sensitivity,response ratio,response time,and recovery time to establish an efficiency detection level of the GHG emissions.A literature review of 95 different studies showed that palladium-tin dioxide(Pd-SnO2)nano particles,indium oxide(In2O3)nano wires,and gold-lanthanum oxide-doped tin dioxide(AuLa2O3/SnO2)nanofibers had better performance compared to other sensing materials in CH4-,N2O-,and CO2-based sensors,respectively.The findings from reviewed studies revealed that nanoporous structures,nano wires,and nano fibers had faster response and recovery compared to conventional materials due to their big specific surface area(SSA).The designed ternary hybrid structure of sensing materials was more effective for CO2gas detection than the double hybrid structure,unlike CH4-and N2O-based sensors.However,constructive suggestions for researchers were discussed in the conclusion based on the current research status and challenges to improve the performance of GHG sensors. 展开更多

Nitrogen dioxide(NO2)plays an important role in atmospheric chemistry.NO2 detection systems with high precision and low interference have gradually developed into an essential components of measurement instruments for peroxy radical,organic nitrates,and the ozone production rate.Accurate and quantitative evaluations of measurement interference are necessary for field applications.Long-term,multi-scale field comparison experiments were conducted in summer(from August 8 to September 15,2019)in Chengdu,China,in this study to compare three NO2 measurement techniques:cavity ring-down spectroscopy(CRDS),photolytic conversion-chemiluminescence detector(PC-CLD),and cavity-enhanced absorption spectroscopy(CEAS).The results obtained from these three instruments were consistent throughout the entire dataset.Various interference factors were quantitatively analyzed that demonstrated the nitrous acid photolysis impact on the PC-CLD fluorescence signal and the influence of aldehyde absorption on the optical cavity technology were negligible under actual field conditions.Under high ozone pollution and high particulate pollution conditions,the results indicated that the three instruments reliably obtained NO2 data under this complex air pollution environment.Some deviations might have occurred during high temperature conditions,the extent of overestimation was dependent on the photochemical age of an air mass defined as-log10(NOx/NOy).PC-CLD tended to exhibit an overestimation of nearly 20%when the-log10(NOx/NOy)exceeded 0.5,and a portion of this overestimation could be attributed to peroxy nitrates.In the future,further comparisons among various NO2 measurement techniques is meaningful to analyze potential interferences and improve atmospheric chemistry comprehension. 展开更多

Background:Poly(ADP-ribose)polymerase(PARP)inhibitors(PARPi)are established maintenance treatments in ovarian cancer,but comparative efficacy across genetic profiles and relapse risk categories remains unclear.The aim of this study was to compare the efficacy of different PARPi as maintenance therapy in ovarian cancer across genetic profiles and relapse risk categories using reconstructed individual patient data(IPD)from randomized trials(RCTs).Methods:IPD were reconstructed using the IPDfromKM method from published Kaplan-Meier curves of RCTs stratified by clinical risk subgroup.Progression-free survival(PFS)was the primary endpoint.Three comparisons were performed:Breast Cancer gene(BRCA)+high-risk,Homologous Recombination Deficiency(HRD)+/BRCAwt high-risk,and BRCA+low-risk populations.Restricted Mean Survival Time(RMST)was calculated as a supplementary measure,with curves truncated at 66 months.Results:In the BRCA+high-risk population,olaparib monotherapy(median PFS 41.2 months)and olaparib plus bevacizumab(median PFS 42.5 months)demonstrated the greatest PFS benefit,marginally outperforming niraparib(median PFS 31.2 months).RMST analysis showed a 14-month advantage for olaparib plus bevacizumab over bevacizumab alone.In the HRD+/BRCAwt high-risk population,olaparib plus bevacizumab and niraparib showed comparable efficacy,with no statistically significant inter-treatment difference.In the BRCA+low-risk population,olaparib plus bevacizumab showed superior HR versus olaparib monotherapy,without reaching statistical significance.RMST analysis also indicated an advantage of 8.5 months for the combination,though this did not reach statistical significance.Conclusions:PARPi treatment benefit in ovarian cancer is meaningfully influenced by genetic profile and relapse risk,supporting biomarker-driven treatment selection in clinical practice. 展开更多

To predict the ranking of the country’s innovation capability in the world in real-time,this study designs a twophased prediction model based on the pairwise comparison.Data from the global innovation index(GII)reports are employed in this study.Countries with different income levels have shown different development inertias,the two-phased prediction model is thus proposed.In the first phase,the GII data from the previous year are applied to predict the ranking of innovation capability for high-income countries.In the second phase,more years of historical data are adopted to predict the innovation ranking for other countries.The global innovation rankings for all countries and economies are thus obtained.Experiments have proved that the model requires only a few indicators to get accurate results.The model provides real-time decision support for decision-makers to formulate innovative development policies. 展开更多

Objectives:Drawing on the motivational perspective of the social comparison theory and the relevant literature on trait self-compassion,the objective of this research article is to examine that,during young adults’passive social media use,how their trait self-compassion is related to their self-improvement or self-destruction motivations,which in turn are related to their assimilative or contrastive upward social comparison,which correspondingly is related to their positive or negative psychological well-being.Methods:the current study administered a cross-sectional survey to American college students who used social media.Participants first reported their trait self-compassion.Afterwards,participants reported that,when they used social media the last time,the frequencies that they passively used social media,their self-improvement and self-destruction motivations,their assimilative and contrastive upward social comparison,and their psychological well-being.Results:During passive use of social media,young adults with high trait self-compassion were likely to have more self-improvement(than self-destruction)motivations,which in turn were likely to compare with others more upwardly assimilative(than contrastive),which in turn were likely to have more favorable(than unfavorable)psychological well-being.Conversely,those with more self-destruction(than self-improvement)motivations were likely to compare with others more upwardly contrastive(than assimilative),which in turn were likely to have more unfavorable(than favorable)psychological well-being.Conclusions:The current study makes contributions by adding the motivational perspective of the social comparison theory and the relevant literature on trait self-compassion to more comprehensive explain the associations between passive social media use,upward social comparison,and psychological well-being of young adults.Findings could also offer valuable suggestions on promoting the psychological well-being of young adult social media users. 展开更多

Based on RT-DETR-L,this paper systematically compares five attention mechanisms(SE,CBAM,CA,ECA,and EMA)at the P3/P4/P5 outputs of the feature-pyramid neck under identical training conditions,and evaluates FasterNet backbone replacement and a P2 small-object detection head as complementary improvements.Experiments reveal a performance gap of up to 4.29 percentage points(CA:93.04%to EMA:97.33%in mAP50),indicating that the choice of attention mechanism has a substantial impact on RT-DETR-type PCB detectors.EMA achieves the best mAP50(97.33%)and the highest mAP50:95(56.45%);ECA offers a competitive trade-off without increasing GFLOPs(96.69%);CA performs worst(93.04%),a 3.34 pp drop below the baseline,tentatively attributed to an architectural conflict with the AIFI encoder.FasterNet backbone replacement trades accuracy for efficiency(31%fewer parameters,40%lower GFLOPs);and,when trained from scratch on the second dataset DeepPCB,the EMA variant again yields the largest gain(mAP5089.33%,+4.83 pp over the baseline),showing that the improvement is not specific to a single dataset. 展开更多

Driven by rapid technological advancements and economic growth,mineral extraction and metal refining have increased dramatically,generating huge volumes of tailings and mine waste(TMWs).Investigating the morphological fractions of heavy metals and metalloids(HMMs)in TMWs is key to evaluating their leaching potential into the environment;however,traditional experiments are time-consuming and labor-intensive.In this study,10 machine learning(ML)algorithms were used and compared for rapidly predicting the morphological fractions of HMMs in TMWs.A dataset comprising 2376 data points was used,with mineral composition,elemental properties,and total concentration used as inputs and concentration of morphological fraction used as output.After grid search optimization,the extra tree model performed the best,achieving coefficient of determination(R2)of 0.946 and 0.942 on the validation and test sets,respectively.Electronegativity was found to have the greatest impact on the morphological fraction.The models’performance was enhanced by applying an ensemble method to the top three optimal ML models,including gradient boosting decision tree,extra trees and categorical boosting.Overall,the proposed framework can accurately predict the concentrations of different morphological fractions of HMMs in TMWs.This approach can minimize detection time,aid in the safe management and recovery of TMWs. 展开更多

Multi-firmware comparison techniques can improve efficiency when auditing firmwares in bulk.How-ever,the problem of matching functions between multiple firmwares has not been studied before.This paper proposes a multi-firmware comparison method based on evolutionary algorithms and trusted base points.We first model the multi-firmware comparison as a multi-sequence matching problem.Then,we propose an adaptation function and a population generation method based on trusted base points.Finally,we apply an evolutionary algorithm to find the optimal result.At the same time,we design the similarity of matching results as an evaluation metric to measure the effect of multi-firmware comparison.The experiments show that the proposed method outperforms Bindiff and the string-based method.Precisely,the similarity between the matching results of the proposed method and Bindiff matching results is 61%,and the similarity between the matching results of the proposed method and the string-based method is 62.8%.By sampling and manual verification,the accuracy of the matching results of the proposed method can be about 66.4%. 展开更多

Previous bidirectional quantum private comparison(BQPC)protocols cannot meet the requirements in some special application scenarios,where only one party needs to obtain the comparison results without a third party(TP),such as scenarios for authority surveys or healthcare data sharing.In addition to this,the BQPC protocol has the potential of information leakage in multiple comparisons.Therefore,we design a new unidirectional quantum private comparison(UQPC)protocol based on quantum private query(QPQ)protocols with ideal database security and zero failure probability(IDS-ZF),for the reason that they have excellent unidirectionality and security.Concretely,we design a UQPC protocol based on Wei et al.’s work[IEEE Transactions on Computers 672(2017)]and it includes an authentication process to increase the resistance to outside attacks.Moreover,we generalize the protocol and propose a general model that can transform a QPQ protocol with or without the IDS-ZF property into a secure UQPC protocol.Finally,our study shows that protocols using our model are secure,practical,and have the IDS-ZF property. 展开更多

Tailings produced by mining and ore smelting are a major source of soil pollution.Understanding the speciation of heavy metals(HMs)in tailings is essential for soil remediation and sustainable development.Given the complex and time-consuming nature of traditional sequential laboratory extraction methods for determining the forms of HMs in tailings,a rapid and precise identification approach is urgently required.To address this issue,a general empirical prediction method for HM occurrence was developed using machine learning(ML).The compositional information of the tailings,properties of the HMs,and sequential extraction steps were used as inputs to calculate the percentages of the seven forms of HMs.After the models were tuned and compared,extreme gradient boosting,gradient boosting decision tree,and categorical boosting methods were found to be the top three performing ML models,with the coefficient of determination(R2)values on the testing set exceeding 0.859.Feature importance analysis for these three optimal models indicated that electronegativity was the most important factor affecting the occurrence of HMs,with an average feature importance of 0.4522.The subsequent use of stacking as a model integration method enabled the ability of the ML models to predict HM occurrence forms to be further improved,and resulting in an increase of R2 to 0.879.Overall,this study developed a robust technique for predicting the occurrence forms in tailings and provides an important reference for the environmental assessment and recycling of tailings. 展开更多

The NEutron Detector Array(NEDA)is designed to be coupled to gamma-ray spectrometers to enhance the sensitivity of the setup by enabling reaction channel selection through counting of the evaporated neutrons.This article presents the implementation of a double trigger condition system for NEDA,which improves the acquisition of neutrons and reduces the number of gamma rays acquired.Two independent triggers are generated in the double trigger condition system:one based on charge comparison(CC)and the other on time-of-flight(TOF).These triggers can be combined using OR and AND logic,offering four distinct trigger modes.The developed firmware is added to the previous one in the Virtex 6 field programmable gate array(FPGA)present in the system,which also includes signal processing,baseline correction,and various trigger logic blocks.The performance of the trigger system is evaluated using data from the E703 experiment performed at GANIL.The four trigger modes are applied to the same data,and a subsequent offline analysis is performed.It is shown that most of the detected neutrons are preserved with the AND mode,and the total number of gamma rays is significantly reduced.Compared with the CC trigger mode,the OR trigger mode allows increasing the selection of neutrons.In addition,it is demonstrated that if the OR mode is selected,the online CC trigger threshold can be raised without losing neutrons. 展开更多

Background:Platform algorithms driving content presentation are profoundly shaping the experience of younger users.While prior research has examined anxiety stemming from young adults’social media usage,the link between upward social comparison and anxiety remains unclear.This study aims to investigate the mediating role of upward social comparison in this relationship and determine the moderating role of psychological resilience.Methods:A cross-sectional survey was conducted among 562 young Chinese adults aged 18–35(53%female).Data were collected via an online questionnaire employing validated measurement instruments,including scales for social media usage patterns,upward comparator behaviour(INCOM),anxiety levels(GAD-7),and psychological resilience(RSA).Correlation analysis,mediation analysis,and moderation analysis were conducted using SPSS 29.0.Results:As predicted,the results indicate that upward social comparison mediates the relationship between both active(β=−0.11,95%CI=[−0.15,−0.08])and passive(β=0.11,95%CI=[0.07,0.15])social media use and anxiety.Furthermore,psychological resilience(βlow=0.10,95%CI=[0.06,0.14];βhigh=0.05,95%CI=[0.01,0.09])moderated the indirect effect of passive social media use on anxiety through upward social comparison.Conclusion:The findings indicate that upward social comparison significantly influences the anxiety experienced by young social media users,with psychological resilience playing a crucial moderating role.These results offer valuable insights for optimizing content recommendation algorithms on social media platforms to better support young adults’mental health. 展开更多

To address the installation challenges of a 2-m ring Gregorian telescope system,and similar optical systems with a small width-to-radius ratio,we propose a detection method combining local interferometry with a comparison model.This method enhances the precision of system calibration by establishing a dataset that delineates the relationship between secondary mirror misalignment and wavefront aberration,subsequently inferring the misalignment from interferometric detection results during the calibration process.For the 2-m ring telescope,we develop a detection model using five local sub-apertures,enabling a root-mean-square detection accuracy of 0:0225λ(λ=632:8 nm)for full-aperture wavefront aberration.The calibration results for the 2-m Ring Solar Telescope system indicate that the root-mean-square value of sub-aperture wavefront aberration reaches 0.104λ,and the root-mean-square value of spliced full-aperture measurement yields reaches 0.112λ.This method offers a novel approach for calibrating small width-toradius ratio telescope systems and can be applied to the calibration of other irregular-aperture optical systems. 展开更多
