However, limited information is available on their anisotropy, and even less is known about the correlation between structure, overconsolidation, and anisotropy. In this study, the undrained anisotropy characteristics of shear strength and small-strain shear stiffness in upper Shanghai Layers 2–6 clays were thoroughly assessed using a series of K0-consolidated undrained triaxial compression (TC) and triaxial extension (TE) tests (K0 is the coefficient of lateral earth pressure at rest). The effective stress paths, shear strength, and small-strain shear stiffness from the undrained TC and TE tests demonstrate the anisotropic behaviors in upper Shanghai clays. Analyses of data from upper Shanghai clays and other clays worldwide indicate that the shear strength anisotropy ratio (Ks) converges at 0.8 as the overconsolidation ratio (OCR) and plasticity index (Ip) increase, while the small-strain shear stiffness anisotropy ratio (Re) converges at 1.0. The influence of OCR on Ks and Re is more pronounced than that of Ip and sensitivity (St). Nevertheless, no clear correlation between Ks and Re is observed in upper Shanghai clays.展开更多

In the...The goal of this research is to describe and analyze Shanghai’s fashion during Republic Period. Shanghai’s fashion during Republic Period plays a special role in fashion history of China and Shanghai history. In the paper, three aspects including the fashion centre of China as well as Far East, men’s fashion and women’s fashion in Shanghai are discussed. The style, textiles, color, decoration and combination of clothing are described. Many costumes from the Clothing Museum at Donghua University and private collections as well as some historical writings, photographs and publications are elucidated and corroborated to give a more detailed description about Shanghai’s fashion during that period.Here are some tentative conclusions. Firstly, Shanghai had always been the fashion center in China even Far East during Republic Period. Modeng was the main reflection of Shanghai fashion. Secondly, the traditional clothing exerted less influence and was less widely used, some kinds and combinations were out of fashion gradually. The fashion was described to be highly stylized, exquisite and concise. Thirdly, the influence of Western Style was further greater. The fashion in Shanghai was almost synchronous with fashion of Paris. Some western clothing was directly used in daily life and the elements of Western Style had an increasingly wide utilization. Fourthly, the New Chinese Style whose representatives were Qipao and Zhongshan Zhuang appeared and popularized in Shanghai. The fashion of Qipao changed frequently. Finally, the fashion in Shanghai called Shanghai Style could be summarized fashionable, exquisite, rapidly changeable, which is harmonious of both ancient and modern, Chinese and foreign.展开更多

文摘As low-altitude airspace becomes increasingly accessible and eVTOL(electric vertical take-off and landing)technologies advance,the low-altitude economy has emerged as a transformative frontier in urban mobility and industrial restructuring.Although countries face comparable technological opportunities,their development paths diverge significantly.This divergence is shaped not only by policy choices and innovation capacity but also by underlying differences in institutional architectures,resource configurations,and implementation mechanisms.This paper proposes a Development Path Evolution Model grounded in four structural elements:technological capability,institutional systems,infrastructure,and application scenarios.Based on this framework,the study identifies three archetypal path types(technology-led,institution-led,and scenario-driven)and empirically validates the model through comparative case studies of the United States,Europe,and Japan.Applying the model to China reveals a distinct"hybrid scenario-driven path",characterized by demand-responsive pilots,decentralized institutional flexibility,and strong engineering capacity.Using Shanghai as a representative case,the study outlines five strategic levers to guide its transition from a localized pilot zone to a platform-based governance hub with national and international relevance.The research contributes to theoretical understanding of path differentiation in emerging industries and provides actionable insights for developing economies with strong mobilization capacity and industrial ecosystems.

文摘Comprehensive investigations have been conducted to study the structure and overconsolidation of upper Shanghai clays, i.e. Layers 2–6 clays, typically located at depths of 30–40 m. However, limited information is available on their anisotropy, and even less is known about the correlation between structure, overconsolidation, and anisotropy. In this study, the undrained anisotropy characteristics of shear strength and small-strain shear stiffness in upper Shanghai Layers 2–6 clays were thoroughly assessed using a series of K0-consolidated undrained triaxial compression (TC) and triaxial extension (TE) tests (K0 is the coefficient of lateral earth pressure at rest). The effective stress paths, shear strength, and small-strain shear stiffness from the undrained TC and TE tests demonstrate the anisotropic behaviors in upper Shanghai clays. Analyses of data from upper Shanghai clays and other clays worldwide indicate that the shear strength anisotropy ratio (Ks) converges at 0.8 as the overconsolidation ratio (OCR) and plasticity index (Ip) increase, while the small-strain shear stiffness anisotropy ratio (Re) converges at 1.0. The influence of OCR on Ks and Re is more pronounced than that of Ip and sensitivity (St). Nevertheless, no clear correlation between Ks and Re is observed in upper Shanghai clays.

文摘Mudflat vegetation plays a crucial role in the ecological function of wetland environment,and obtaining its fine spatial distri-bution is of great significance for wetland protection and management.Remote sensing techniques can realize the rapid extraction of wetland vegetation over a large area.However,the imaging of optical sensors is easily restricted by weather conditions,and the backs-cattered information reflected by Synthetic Aperture Radar(SAR)images is easily disturbed by many factors.Although both data sources have been applied in wetland vegetation classification,there is a lack of comparative study on how the selection of data sources affects the classification effect.This study takes the vegetation of the tidal flat wetland in Chongming Island,Shanghai,China,in 2019,as the research subject.A total of 22 optical feature parameters and 11 SAR feature parameters were extracted from the optical data source(Sentinel-2)and SAR data source(Sentinel-1),respectively.The performance of optical and SAR data and their feature paramet-ers in wetland vegetation classification was quantitatively compared and analyzed by different feature combinations.Furthermore,by simulating the scenario of missing optical images,the impact of optical image missing on vegetation classification accuracy and the compensatory effect of integrating SAR data were revealed.Results show that:1)under the same classification algorithm,the Overall Accuracy(OA)of the combined use of optical and SAR images was the highest,reaching 95.50%.The OA of using only optical images was slightly lower,while using only SAR images yields the lowest accuracy,but still achieved 86.48%.2)Compared to using the spec-tral reflectance of optical data and the backscattering coefficient of SAR data directly,the constructed optical and SAR feature paramet-ers contributed to improving classification accuracy.The inclusion of optical(vegetation index,spatial texture,and phenology features)and SAR feature parameters(SAR index and SAR texture features)in the classification algorithm resulted in an OA improvement of 4.56%and 9.47%,respectively.SAR backscatter,SAR index,optical phenological features,and vegetation index were identified as the top-ranking important features.3)When the optical data were missing continuously for six months,the OA dropped to a minimum of 41.56%.However,when combined with SAR data,the OA could be improved to 71.62%.This indicates that the incorporation of SAR features can effectively compensate for the loss of accuracy caused by optical image missing,especially in regions with long-term cloud cover.

文摘The nine typical Shanghai soils are usually silty clay or clay,which appears inconsistent with their low clay content in the relevant publications.The literature review shows that the documented clay content of Shanghai soils ranges from 0%to 30.8%by weight.This inconsistency may stem from two factors:(1)the Shanghai soil classification system relies solely on the plasticity index for soil naming;and(2)the conventional steel sieving method cannot separate the clay from the fine soils(clay and silt mixtures).This paper aims to accurately determine the clay content in Shanghai soils.It uses nylon cloth sieves with apertures ranging from 0.063 mm to 0.0008 mm and completely separates the clay particles from the fine soils.The nine typical Shanghai soils are tested and sieved into distinct subgroups of clay,silt,sand,and gravel particles.Results demonstrate clay content ranges from 18.99%to 79.33%,substantially higher than literature values and consistent with their names of either silty clay or clay.Macro,micro,and scanning electron microscope(SEM)images reveal effective separation of clay,silt,sand,and gravel particles.The clay exhibits cohesive properties,while the silt,sand,and gravel comprise clean,non-cohesive individual particles.The clay and silt fractions are confirmed to be within their respective sieving limits by SEM-based particle size measurements.Additionally,Atterberg limits testing highlights the high plasticity of the clay particles and the non-plastic nature of the silt particles.

文摘Objective:To evaluate the phenotypic resistance profile of Aedes(Ae.)albopictus against multiple insecticides and to delineate the frequency and pyrethroid-resistance association of knockdown resistance(kdr)mutations V1016G,I1532T and F1534S in Ae.albopictus in Pudong New Area,Shanghai,China.Methods:From June to July 2024,a total of 1249 Ae.albopictus eggs and 4732 adults were collected from five towns in the Pudong New Area.These collected specimens were then reared to obtain the F1 generation including 10235 larvae at the late 3rd to early 4th instar stages,as well as 5800 non-blood-fed adults aged 3 to 5 days.Larval resistance was assessed via the immersion method,and adult resistance via the contact tube method.For the larval,0≤resistance ratio(RR)<3 indicates sensitivity;3≤RR<10 denotes low resistance;10≤RR<40 signifies moderate resistance;RR≥40 represents high resistance.While for adults,a mortality rate of≥98%stands for sensitivity,80%≤mortality rate<98%indicates suspected resistance,and mortality rate<80%denotes a resistant population.A pooled sequencing strategy(8 sample pools)was used to detect genotype kdr mutations including V1016G,I1532T,F1534S in the voltage-gated sodium channel(VGSC)gene.Results:Ae.albopictus larvae displayed low resistance to fenthion(RR=5.85),temephos(RR=4.63)and β-cypermethrin(RR=3.20),but remained fully susceptible to propoxur(RR=0.33).Adults showed incipient resistance to β-cypermethrin(mortality:92.7%),lambda-cyhalothrin(mortality:96.8%)and permethrin(mortality:86.6%),while remained sensitive to propoxur(mortality:100%).For Ae.albopictus population in the Pudong New Area,pyrethroid tolerance was primarily driven by F1534S mutation,which was amplified when the mutation was paired with V1016G or I1532T.Conclusions:These findings highlight the need for integrated resistance monitoring and targeted insecticide rotation-such as prioritizing propoxur for Ae.albopictus larval and adult control-to mitigate resistance spread and preserve vector management efficacy.
文摘Dear Editor,Since 2024,the clade 2.3.4.4b highly pathogenic avian influenza(HPAI)H5N1 viruses have been identified in dairy cattle in the United States,raising global concerns about public health(Neumann and Kawaoka,2024).As of December 18,2024,the U.S.Centers for Disease Control and Prevention(CDC)has reported over 61 confirmed cases of H5N1 infection in humans,predominantly associated with exposure to infected poultry or dairy cattle(U.S.Centers for Disease Control and Prevention,2024).Notably,the circulating 2.3.4.4b H5N1 clade has demonstrated continuous evolution in both wild and domestic birds globally,with expanding mammalian host tropism that now includes swine,cats,red foxes,harbor seals,and skunks(Peacock et al.,2024).These viruses have not only incurred substantial economic impacts but also posed dual threats to human health and ecological stability particularly during co-infections with other viruses(Abolnik,2024;Wang and Wang,2023).

文摘Large-scale synoptic patterns significantly affect meteorological conditions and air pollution,yet their impacts on the vertical distribution of formaldehyde(HCHO)and nitrogen dioxide(NO_(2))have been little studied.From 1 June 2020 to 31 December 2021,Multi-AXis-Differential Optical Absorption Spectroscopy(MAX-DOAS)was used to observe NO_(2) and HCHO vertical profiles in three typical environments of Shanghai,China,representing urban,suburban and coastal rural environments,respectively.HCHO level is the highest at suburban site,NO_(2) is the highest at urban site.HCHO is mainly distributed between 0 and 1 kmin altitude,and NO_(2) is concentrated near the ground.The ratio of HCHO to NO_(2) is used to identify ozone formation regimes,ozone sensitivities vary with environmental area,season and altitude.The principal component analysis in the T-mode approach and typhoon“In-Fa”case is applied to analyze the effects of synoptic patterns on HCHO and NO_(2) vertically.HCHO concentrations show a pattern of low-pressure type>uniform-pressure type>high-pressure type at each altitude layer,while NO_(2) concentrations follow the opposite pattern.Meteorological factors(especially radiation,temperature,relative humidity,cloud cover and wind),external transport and initial emissions contribute to the differences in HCHO and NO_(2) levels across synoptic types.The“In-Fa”case shows how this special synoptic pattern elevates HCHO and NO_(2) levels by improving meteorological conditions,boosting biogenic precursors and shifting air mass directions.This study assesses the impacts of synoptic patterns on HCHO and NO_(2) vertical distribution in Shanghai,offering insights into understanding causes of pollution.

文摘Atmospheric dimethyl sulfide(DMS,CH_(3)SCH_(3))and methanethiol(MeSH,CH_(3)SH)have been widely studied and recognized to significantly constrain the atmospheric sulfur budget.Nevertheless,while the role of DMS and MeSH remains largely uncertain in inland regions,learning about dimethyl disulfide(DMDS,CH_(3)SSCH_(3))is also limited.In this study,we measured atmospheric DMS,MeSH and DMDS in winter,from 19 December 2022 to 30 January 2023,and spring,from 24 April to 2 June 2023 with a Vocus proton-transfer-reaction time-offlightmass spectrometer(Vocus PTR-TOF)at the Dianshan Lake(DSL)Air QualityMonitoring Supersite in a suburban area of Shanghai,China.The mixing ratios of DMS,MeSH and DMDS exhibited clear diurnal cycles,and were characterized by average and interquartile range values of 22.6(10.1-29.7),14.9(6.5-19.4)and 9.8(6.0-10.7)pptv,respectively,in the spring campaign,which are approximately twice as high as those in winter.MeSH and DMDS were found to be well correlated with DMS in the two campaigns.Wind analysis suggests that three reduced-sulfur compounds owned common sources from the DSL.Furthermore,the sulfur dioxide(SO_(2))production quantity fromthe three reduced-sulfur compounds over the DSL inMay 2023 was estimated to be 1.42±0.74 t with 84.8%originating fromDMDS,which was comparable to the monthly SO_(2) emissions fromships over the DSL.Our results highlight the prominent role of atmospheric DMDS in SO_(2) production when compared to DMS and MeSH in the suburban area of Shanghai,soliciting further investigation and consideration of DMDS in the sulfur budget.
文摘Objective:This study aimed to explore undergraduates’knowledge,attitude,and practice/behavior of human papillomavirus(HPV)vaccination,as well as the essential influencing factors for vaccination decision-making.Methods:Through cluster and convenience sampling,2000 undergraduates from the Nursing and Language department of a university in Shanghai were sent a self-designed questionnaire.Chi-square tests,independent sample t-test/ANOVE,and multiple linear regression were used to investigate participants’knowledge and attitude on HPV vaccination,as well as the factors that predicted potential action to receive and promote HPV vaccination in the future.Results:The mean HPV knowledge score was 5.027 out of 10.Health science students showed a significantly higher knowledge mean score than the non-health science students(P<0.000).There was a statistically difference in HPV vaccination attitude among undergraduates in different grades(P<0.05).Awareness of cervical cancer and worries about the risk of cervical cancer were the significant predictors of willingness to receive and promote HPV vaccination in the future.Conclusions:It would take time for a new health product to be aware,understood,accepted,and received.Education providing and information sharing are expected to break the dawn and make the procedure processed.

文摘Objective To assess the independent and combined effects of air pollutants,meteorological factors,and greenspace exposure on new tuberculosis(TB)cases.Methods TB case data from Shanghai(2013–2018)were obtained from the Shanghai Center for Disease Control and Prevention.Environmental data on air pollutants,meteorological variables,and greenspace exposure were obtained from the National Tibetan Plateau Data Center.We employed a distributed-lag nonlinear model to assess the effects of these environmental factors on TB cases.Results Increased TB risk was linked to PM_(2.5),PM_(10),and rainfall,whereas NO_(2),SO_(2),and air pressure were associated with a reduced risk.Specifically,the strongest cumulative effects occurred at various lags:PM_(2.5)(RR=1.166,95%CI:1.026–1.325)at 0–19 weeks;PM_(10)(RR=1.167,95%CI:1.028–1.324)at 0–18 weeks;NO_(2)(RR=0.968,95%CI:0.938–0.999)at 0–1 weeks;SO_(2)(RR=0.945,95%CI:0.894–0.999)at 0–2 weeks;air pressure(RR=0.604,95%CI:0.447–0.816)at 0–8 weeks;and rainfall(RR=1.404,95%CI:1.076–1.833)at 0–22 weeks.Green space exposure did not significantly impact TB cases.Additionally,low temperatures amplified the effect of PM_(2.5)on TB.Conclusion Exposure to PM_(2.5),PM_(10),and rainfall increased the risk of TB,highlighting the need to address air pollutants for the prevention of TB in Shanghai.
文摘The goal of this research is to describe and analyze Shanghai’s fashion during Republic Period. Shanghai’s fashion during Republic Period plays a special role in fashion history of China and Shanghai history. In the paper, three aspects including the fashion centre of China as well as Far East, men’s fashion and women’s fashion in Shanghai are discussed. The style, textiles, color, decoration and combination of clothing are described. Many costumes from the Clothing Museum at Donghua University and private collections as well as some historical writings, photographs and publications are elucidated and corroborated to give a more detailed description about Shanghai’s fashion during that period.Here are some tentative conclusions. Firstly, Shanghai had always been the fashion center in China even Far East during Republic Period. Modeng was the main reflection of Shanghai fashion. Secondly, the traditional clothing exerted less influence and was less widely used, some kinds and combinations were out of fashion gradually. The fashion was described to be highly stylized, exquisite and concise. Thirdly, the influence of Western Style was further greater. The fashion in Shanghai was almost synchronous with fashion of Paris. Some western clothing was directly used in daily life and the elements of Western Style had an increasingly wide utilization. Fourthly, the New Chinese Style whose representatives were Qipao and Zhongshan Zhuang appeared and popularized in Shanghai. The fashion of Qipao changed frequently. Finally, the fashion in Shanghai called Shanghai Style could be summarized fashionable, exquisite, rapidly changeable, which is harmonious of both ancient and modern, Chinese and foreign.
