Currently,investigations of the color attributes of Foshan Woodblock New Year Paintings are limited to qualitative descriptions,devoid of objective quantitative data backing.Their color solutions fail to satisfy the distribution and creative requirements of the digital era.This study intends to utilize K-means clustering to calculate and analyze the color properties of Foshan Woodblock New Year Paintings.Incorporating contemporary display standards,this study examines color palettes consistent with traditional New Year Paintings culture.Firstly,a dataset consisting of 127 photos categorized into 6 principal types of Foshan Woodblock New Year Paintings was assembled.Images were subjected to pre-processing,which included color correction and noise reduction.Then,following the conversion of data from RGB to HSV color space to extract pixel vectors,the K-means algorithm was implemented with a specified K value for clustering.Primary colors were derived from both the comprehensive information and specific groups to create color schemes.Ultimately,in light of contemporary digital display attributes,the S and V values of cluster centers were moderately modified while maintaining conventional color characteristics to augment visual impact in digital distribution.The clustering results showed that Foshan Woodblock New Year Paintings display attributes of high saturation and pronounced value contrast,with prominent colors primarily consisting of high-saturation reds.This resulted in one comprehensive color scheme and six categorized schemes.This study offers methodological assistance for the quantitative analysis of New Year painting colors,providing practical recommendations for the innovative distribution of traditional New Year Paintings in contemporary media,and is crucial for the preservation and transmission of intangible cultural heritage. 展开更多

To adapt to national climate change strategies,understanding the thermal vulnerability of urban functional zones(UFZs)is critical for enhancing the livability and sustainable development of cities.We address the limitations of existing thermal vulnerability assessments by incorporating human perception into the analysis.Specifically,we introduce the sky openness index to reflect human perception of the thermal environment and examine variations in thermal vulnerability across different UFZs.Using the Extreme Gradient Boosting(XGBoost)-SHapley Additive exPlanations(SHAP)model,we analyze the contributions of 2D and 3D urban form indicators to thermal vulnerability and link these contributions to the unique needs and vulnerability characteristics of UFZs of Foshan City,China in 2023.The results reveal that:1)high-value heat-fragile areas(1.74–2.00]constitute 10.42%of Foshan City;2)traffic zone and publiccommercial zone exhibit the highest levels of thermal vulnerability;and 3)building height and the normalized building index are the most influential factors,with contributions of|0.06|and|0.03|,respectively.We provide a scientific foundation for developing governance strategies to promote urban resilience. 展开更多

Driven by climate change,viral evolution,intensified human mobility,and increasing population susceptibility,mosquito-borne diseases are extending their geographic range and public health impact worldwide.The 2025 chikungunya outbreak in Foshan,Guangdong Province,provided a critical real-world assessment of the province's local surveillance and emergency response system.This commentary aims to elucidate the effectiveness,strengths,and limitations of Foshan's outbreak response,and to identify lessons for strengthening early warning and vectorborne disease preparedness.Containment was achieved within three weeks through coordinated multi-sectoral emergency activation,rapid case detection,and precision vector control.However,the response also exposed systemic vulnerabilities,including delayed activation of warning mechanisms,limitations in entomological surveillance,and deficiencies in multi-source data integration.Addressing these gaps will require establishing a multi-source,data-driven early warning system;institutionalizing standardized cross-border surveillance and response protocols;expanding genomic and epidemiological research capacity;and strengthening research capacities and workforce resources from a global perspective to enhance global preparedness against emerging mosquito-borne diseases. 展开更多

Digital industrial clusters are a core driver of high-quality regional economic development.Building on its strong manufacturing base,Foshan has actively developed digital industrial clusters,yet still faces practical challenges such as insufficient collaboration and digital imbalance.Based on complex network theory,this study employs a mixed-methods approach by combining the DBSCAN spatial clustering algorithm,questionnaire surveys,and multiple case studies,to examine the characteristics,challenges,and development pathways of Foshan’s digital industrial clusters.The findings reveal that Foshan’s digital industrial clusters exhibit a three-tier hierarchical structure of‘core,intermediate,and small’clusters.Core clusters are concentrated in Chancheng District,demonstrating combined advantages in quantity,scale,and density.However,the cluster development faces several prominent issues:micro and small enterprises constitute over 55% of the total,yet their digital coverage rate is only 12%;product homogenization leads to intense competition;significant disparities exist among enterprises in the timing and investment of digital transformation;and collaboration barriers arise from over-reliance on core enterprises and insufficient resource sharing.Accordingly,this study proposes recommendations including optimizing the clusters’hierarchical functions,constructing collaborative innovation platforms,implementing differentiated support policies,and deepening industry-university-research cooperation.The aim is to provide practical references for Foshan to overcome the dilemma of clusters being“physically agglomerated but not functionally integrated”and to promote successful digital upgrading. 展开更多

Background Since July 2025,an outbreak of mosquito-borne chikungunya fever has occurred in Foshan City,Guangdong Province,China.This was the second large-scale local outbreak in China after the one that occurred in Dongguan City,Guangdong Province,in 2010.As of 23 August,more than 10,000 human cases had been reported.This study aims to investigate mosquito infection and viral genomic characteristics during the Foshan outbreak.Methods Adult Aedes albopictus were collected using BioGents Sentinel trap in three hotspot towns(Beijiao,Chencun and Lecong).Mosquitoes were morphologically identified and pooled by species,sex and environment type.Each pool was homogenized,and the homogenate was clarified by centrifugation;and the supernatant was used for viral RNA isolation.The isolated RNA was screened using CHIKV RT-qPCR.Positive pools underwent Sanger sequencing and whole-genome sequencing.The CHIKV lineage and mutational profiles were inferred using maximum likelihood phylogenetic analysis and comparison with human-and mosquito-derived genomes.Results Over 11 days of trapping,2803 mosquitoes were captured.1569(55.97%)female Ae.albopictus were divided into 77 pools and 9.09%(7/77)of these pools were CHIKV-positive.The minimum infection rate(MIR,per 1000 females)for local Ae.albopictus was 4.46,while the MIR for residences in Lecong Town was the highest at 9.17 per 1000 females.The MIR for parklands was slightly higher than for residences(4.60 vs.4.30 per 1000 females).Five complete Ae.albopictus-derived CHIKV genome clustered within the East/Central/South African-Indian Ocean lineage genotype,and harbored novel E1 and E2 mutations consistent with those detected in the 2025 Reunion Island human strain.Amino-acid mutations E1-A226V/E2-L210Q were detected,enhancing adaptability to Ae.albopictus and increasing the transmission capacity.Conclusions This study represents the first mosquito-derived CHIKV whole-genome sequence obtained from the 2025 Foshan outbreak.Ae.albopictus was confirmed as the primary vector,and the presence of adaptive mutations indicated an enhanced transmission potential.Despite the outbreak emerging earlier in the season and affecting a dense urban population,it was effectively controlled through timely and intensive vector interventions.These findings highlighted the critical role of mosquito surveillance in early outbreak preparedness and effective vector management. 展开更多

Introduction:Chikungunya virus(CHIKV),an arthropod-borne alphavirus transmitted by Aedes aegypti and Aedes albopictus,causes fever,severe joint pain,and rash.By 2025,it has triggered outbreaks in 119 countries,endangering 5.5 million people.Recent epidemics in Foshan,China,have strained healthcare systems,underscoring the need to characterize viral load dynamics across infection phases.Methods:We collected 1,156 clinical samples from four Foshan hospitals in July 2025,spanning 6 days before to 12 days after symptom onset.Specimens included serum(904 valid),saliva(22),urine(4),throat swabs(3),and stool(37).CHIKV RNA was quantified via qRT-PCR;timepoints and specimen types with insufficient samples were excluded.Results:Serum showed the highest positivity(90%),followed by saliva(68%),throat swabs(15%),and urine(11%);stool was negative(0%).Serum also had the highest viral loads,confirming its optimal utility.Viral RNA was detectable as early as 1 day presymptom onset(day-1).Days 0–7 post-onset marked explosive replication and elevated loads,representing the optimal sampling window.From Day 8 onward,loads declined,requiring IgG testing to avoid false negatives.Conclusions:Serum is the gold standard for acute CHIKV diagnosis,with superior positivity and viral loads.Pre-symptomatic viral shedding(day-1)supports enhanced port-of-entry screening to intercept imported cases.Days 0–7 post-onset is the optimal sampling window for acute infection.During clearance(day 8+),IgG testing complements molecular diagnostics to reduce gaps.These findings inform evidence-based diagnosis,outbreak control,and resource allocation. 展开更多

Background:Triatomines,also known as kissing bugs,which are found throughout the world and especially in Latin America,are well known natural vectors that transmit American trypanosomiasis,also called Chagas disease.In China,the presence of two species of Triatoma(Triatoma rubrofasciata and T.sinica)was recorded in the past.Due to the growing population and the increasing risk of the global spread of Chagas disease,triatomines became a potential public health nuisance,and in 2016,we started monitoring triatomine activities in southern China.Methods:Triatomine specimens were collected by the National Institute of Parasitic Diseases,Chinese Center for Disease Control and Prevention,and identified by their morphological characteristics under a dissecting microscope.In addition to morphological analysis,the genomic DNA of the specimens was extracted,and the mitochondrial 16S rRNA,the cytochrome b(CytB)gene and the nuclear ribosomal 28S rRNA gene were PCRamplified to analyze and confirm the species genetically.Results:One female adult insect and one male adult insect were collected in a dwelling in the rural area of Shunde County,Foshan City,Guangdong Province,China(22°42′44.63″N,113°08′45.34″E).The results from the morphological and genetic analyses indicated that these triatomines were T.rubrofasciata.Conclusions:This is the first time that the occurrence of T.rubrofasciata has been confirmed in Foshan City,Guangdong Province in southern China.Further studies are needed to reach a clearer understanding of the ecology of this species of triatomine,since it has been found to be naturally infected by Trypanosoma cruzi and T.conorhini and there is evidence of its domiciliation capabilities. 展开更多
