This study examines the association between digital technology adoption and supply chain concentration. Using detailed patent description data of publicly listed Chinese companies over 2007-2021, we identify level in those by machine learning. We find concentration is significantly lower when higher. Results from further analysis suggest relation more prominent company, compared to rivals, gains competitive advantage. Meanwhile, age CEO industry firm belongs influence relation. Additionally,...

The empirical retrieval method based on vegetation indices (VIs) has been extensively utilized to estimate the photosynthetic fractional cover (FPV) and non-photosynthetic (FNPV). These indices, however, saturate in high biomass environments are easily influenced by external factors. Three red edge (RE) bands (i.e., RE1, RE2, RE3) available Sentinel-2 satellite, providing new options for estimating FPV FNPV. Here, sensitivity analysis from PROSAIL-PRO simulations provided a theoretical...

Chlorophyll a (Chl-a) in lakes serves as an effective marker for assessing algal biomass and the nutritional level of lakes, its observation is feasible through remote sensing methods. HJ-1 (Huanjing-1) satellite, deployed 2008, incorporates CCD capable 30 m resolution has revisit interval 2 days, rendering it superb choice or supplemental sensor monitoring trophic state lakes. For long-term regional-scale mapping, both imagery evaluation machine learning algorithms are essential. The...

With increasing global warming, environmental protection and green energy have become hotly discussed issues recently. Countries proposed a net-zero carbon emission path, among which low-carbon transportation has been listed as the primary goal of each country. In Taiwan, highest density motorcycles in Asia, electric are an environmentally friendly mobility solution that enjoys greater advantages for development because their eco-friendly energy-saving nature context protection,...

Determining the contribution of gully erosion to total sediment yield is important for enhancing decision-making regarding abatement and soil conservation measures. The dry-hot valley region Jinsha River one most intensive areas in China. However, production this unclear. Instead using source tracing technique commonly employed other studies, study provides a method rapidly reconstructing historical yields based on properties that accumulated an undrained pond at small watershed outlet. We...

Soybean (Glycine max L. Merrill) is one of the most important commercial crops worldwide. However, soybean has undergone severe genetic bottlenecks during domestication (Hyten et al., 2006). It essential to exploit novel sources diversity and expand gene pools for improvement. Plant mutation breeding been widely used by plant breeders create diversity. Ethyl methanesulfonate (EMS) a chemical mutagen believed mainly induce point mutations, which commonly develop mutant populations in (Li...

Senescence is the final phase of leaf development, characterized by key processes which resources trapped in deteriorating leaves are degraded and recycled to sustain growth newly formed organs. As gaseous hormone ethylene exerts a profound effect on progression senescence, both optimal timing amount its biosynthesis essential for controlled development. The rate-limiting enzyme that controls synthesis higher plants ACC synthase (ACS). In this study, we evaluated production revealed an...

Under the digital revolution that spawned in recent years, AI support is raised context of urban design and governance as it aims to match operation developing process. It offers more chances for ensuring equality public participation empowerment, with possibility projection computation integrated social, cultural, physical spaces. Therefore, this research explored how scenario simulation social attributes interaction dimensions can be incorporated into twin city development, which seen a...

With an estimated 2.4 million cases of foodborne illnesses recorded annually in the UK alone, food safety has become a paramount concern among stakeholders. Modern technology positioned streaming platforms as pivotal conduits for disseminating information. Channels such YouTube offer detailed recordings production process, granting consumers extensive visibility journey from farm to table. This increased transparency not only promotes vigilant monitoring practices but also solicits consumer...

The water-rock interactions significantly affect the dissolution and release of dissolved organic matter (DOM) during reinjection mine water into underground reservoir. In this study, surface characteristics chemical composition natural medium from open-pit coal were characterized. waste consists mainly quartz-dominated sandstone (43.64%) mudstone dominated by sanidine (76.36%). During 35-day experiment, two protein-like, one humus-like, fulvic acid-like substances identified PARAFAC. It was...

Fire severity mapping can capture heterogeneous fire patterns over large spatial extents. Although numerous remote sensing approaches have been established, regional-scale at fine scales (<5 m) from high-resolution satellite images is challenging. The of a vast forest that occurred in Southwest China was mapped 2 m resolution by random models using Sentinel and GF series images. This study demonstrated the combination showed some improvement (from 85% to 91%) global classification accuracy...

Leaf senescence is a highly-programmed developmental process regulated by an array of multiple signaling pathways. Our group previously reported that overexpression the protein phosphatase-encoding gene SSPP led to delayed leaf and significantly enhanced cytokinin responses. However, it still unclear how phenotype associated with In this study, we introduced receptor AHK3 knockout into 35S:SSPP background. The phenotypic analysis double mutant revealed loss-of-function reversed induced SSPP....

The dry valley is a unique geographic phenomenon in Southwest China with severe water erosion. However, little known regarding its dominant controls and the discrepancies between subtypes, leading to poor management of To solve these problems, revised universal soil loss equation (RUSLE) Geodetector method were used temperate (DT), warm (DW), hot (DH) valley. Results indicated that valleys suffer erosion value 64.78, 43.85, 33.81 t·ha−1·yr−1. proven be an efficient tool quantify factor It...

With the improvement of coal-mining mechanizations and intensification human activities, organic matter pollution mine water is becoming severe. In this study, chemical compositions influents effluents from 15 treatment stations in mining area bordering Mongolia Shaanxi were measured. The occurrence DOM (dissolved matter) effluent was determined by EEM (excitation emission matrix), combined with PARAFAC (parallel factor analysis) method. removal station Caojiatan coal specifically discussed...

Prompted by the severe effects of COVID-19 pandemic on Taiwan’s cruise industry, this research aims to explore potential role corporate social responsibility (CSR), relationship quality (RQ), and perceived value (PV) in reviving tourism. The central question focuses how these constructs motivate Taiwanese passengers’ engagement tourism shape their electronic word-of-mouth (E-WOM) behavior post-pandemic era. Therefore, a comprehensive theoretical model was proposed evaluate operators’...

Freeze‒thaw (FT) erosion has gradually become more severe due to climate warming, and concerns about FT in ecologically fragile areas (e.g., high-altitude high-latitude areas) continues grow. Tibet, located at the Third Pole of Earth, is also a substantial part underlain with seasonally frozen soil subject erosion. Evaluating sensitivity influential factors Tibet warranted manage ecological environment human production activities. In this study, we investigated spatial distribution...
