    Abstract The intricate interplay among water, energy, food, and ecology underscores the paramount importance of investigating water–energy–food–ecology (WEFE) systems to foster regional sustainable development. In this study, a dynamic simulation model for the WEFE system was formulated using system dynamics, probing alterations in resource supply, demand dynamics, and ecosystem responses to resource shifts. Utilizing Henan Province as a case study and factoring in resource scarcity and environmental pollution, five scenarios were crafted to forecast WEFE system developmental trajectories from 2005 to 2035. The findings revealed the following key insights: (1) Within each subsystem, the food supply–demand balance ratio maintained a robust level of approximately 4.0. Conversely, the water and energy supply–demand balance ratio remained below 1.0 throughout the study period, indicating a worsening trend in the annual misalignment between supply and demand. Carbon dioxide (CO2) emissions are projected to surge by 103%, posing challenges for future CO2 emission reduction efforts. (2) Among the various scenarios, the Green Development (GD) scenario emerged as pivotal for fostering a coordinated development of the WEFE system. Implementation of the GD scenario showcased a notable 38.1% improvement in the resource supply–demand ratio and a 26% reduction in CO2 emissions. (3) Addressing ecosystem feedback, the reduction of carbon emissions emerges as a focal point for future ecological environment enhancement initiatives in Henan Province. Strategic emphasis should be placed on adjusting energy consumption and its structure to propel the healthy development of the ecological environment. This study serves as a guide for managing regional WEFE systems effectively.

    Abstract The low-temperature impact toughness of nodular cast iron can be significantly enhanced by heat treatment, and thus meet the severe service requirements in the fields of high-speed rail and power generation, etc. In order to explore the enhancement mechanism, microstructure, hardness, composition and other characteristics of as-cast and heat-treated nodular cast iron is systematically tested and compared by optical microscopy, microhardness tester, EBSD, SEM, electron probe, and impact toughness testing machine in this study. The results show that heat treatment has little effect on the morphology and size of graphite in nodular cast iron, ignores the effect on the grain size, morphology, and distribution of ferritic matrix, and has little effect on the hardness and exchange of elements, while it is meaningful to find that heat treatment brings about significant decrease in high-angle grain boundaries (HAGB) between 59° and 60°, decreasing from 10% to 3%. Therefore, the significant enhancement of low-temperature impact toughness of nodular cast iron by heat treatment may result from the obvious decrease in HAGB between 59° and 60°, instead of other reasons. From this perspective, the study can provide novel ideas for optimizing the heat treatment process of nodular cast iron.

    Abstract The traditional drought field studies are inadequate to study drought field characteristics from the perspective of trend and periodicity at the same time, especially to compare the interannual and interdecadal variations of different drought types in the drought field to reveal their similarity and difference patterns. The drought field in Pearl River Basin (PRB) was determined in this paper using the standardized precipitation evapotranspiration index (SPEI) and the empirical orthogonal function (EOF)/rotated empirical orthogonal function (REOF). Periodic characteristics and trend features of the drought field were recognized by extreme-point symmetric mode decomposition (ESMD) and other methods. The results showed that from the perspective of regional characteristics five different spatial modes may be used to categorize the interannual drought field of the PRB; there were interannual cycles associated with the southwest-type drought and the northwest-type drought. The central-south-, north-central- and eastern-type droughts had both interannual and interdecadal cycles; during the study period, the PRB's five types of drought revealed a changing tendency as opposed to a straightforward linear trend; from the interannual variation, the southwest-type drought was consistent with the northwest-type drought prior to 2000, and the north-central-type drought was consistent with the eastern-type drought before 2010. HIGHLIGHTS The spatial characteristics and periodic properties of the watershed were identified.; There are five spatial modes in the Pearl River Basin.; Southwestern and northwestern droughts have interannual cycles.; Five types of droughts in the Pearl River Basin showed a fluctuating trend.; The interannual similarity and variability of the five droughts were studied.;

    Abstract The kinetics of intermolecular chain transfer to polymer (CTP) and chain transfer to monomer (CTM), as well as backbiting in solution copolymerization of ethylene and vinyl acetate (VAc), are calculated by density functional theory. An intrinsic rate coefficient for each reaction type, whose Arrhenius parameters are expressed as functions of unreacted monomer composition, is extracted from calculated elementary reactions, and hence it applies to a wide range of fragment compositions of EVA. Backbiting controls the generation of midchain radicals (MCRs) on the backbone, and its rate maximizes at a medium fraction of VAc in the unreacted monomers. CTP plays an insignificant role in MCR generation even at high conversion rates due to its low pre-exponential factor. The concentration of MCRs is quantified and is close to that of ECRs at high conversions and high fractions of VAc in monomers. Additionally, branching characteristics are explored; concentrations of short-chain branching (SCB) and long-chain branching (LCB) are about 0.7-2.5 and 0.1-0.4%, respectively, and drop with VAc fraction rapidly. The role of the migration of MCRs is highlighted, which transforms about 10% of SCB points into LCB points. Disagreeing with insights from laboratory experiments, it is the migration, rather than CTP, which increases the LCB concentration at high conversions.

    Abstract The Haihe River basin is the main grain production base and the highland of economic strategic development in China. Based on daily meteorological data during 1960–2020, the characteristics of drought evolution in the Haihe River basin were analyzed by the standardized precipitation evapotranspiration index (SPEI). Pearson correlation method and cross-wavelet analysis were used to explore the correlation between the SPEI and climate factors (global warming, sunspots, and atmospheric circulation indices). Global warming has led to a trend of increasing drought in the basin, and there is an obvious zonality in the change of the trend, with the strongest impact on the central region of the basin (112°E–120°E, 38°N–41°N). The SPEI was negatively correlated with the number of sunspots. The more sunspots there were, the more severe the drought in the basin. The drought was most susceptible to the El Niño-Southern Oscillation (ENSO) and the Atlantic Multidecadal Oscillation (AMO), followed by the Arctic Oscillation (AO) and the Pacific Decadal Oscillation (PDO). The North Atlantic Oscillation (NAO), the Pacific North America index (PNA), and the Western Pacific index (WP) were the least associated with the drought in the basin. HIGHLIGHTS The drought trend and the relationship between drought and climatic factors were analyzed.; The drought trend is obviously aggravated in the Haihe River basin.; Drought caused by global warming has an obvious zonal trend.; The more sunspots there were, the more severe the drought.; The drought is mainly affected by the ENSO and AMO.;

    Abstract Vascular smooth muscle cells (VSMCs) are an important cellular component of the vascular wall. Restenosis is mainly due to VSMC excessive proliferation. However, little is known about the role of circRNAs in VSMC proliferation and phenotypic switching. Herein, using fluorescence in situ hybridization assay and quantitative real-time polymerase chain reaction, we found that circ-Sirt1 was markedly downregulated in neointimal formation after injury and in VSMCs treated with platelet-derived growth factor BB (PDGF-BB). Bromodeoxyuridine and MTT assays confirmed the inhibitory role of circ-Sirt1 on cell proliferation. Mechanistically, circ-Sirt1 was mainly expressed in the cytoplasm of VSMCs. Through RNA immunoprecipitation and RNA pull-down assays, we found that circ-Sirt1 bound with c-Myc, which protein associated with proliferation of VSMCs. Chromatin immunoprecipitation assay also provided evidence that the overexpression of circ-Sirt1 almost ceased PDGF-BB-induced binding of c-Myc to the promoter of cyclin B1 in VSMCs. These results indicated that circ-Sirt1 had an inhibitory effect on c-Myc activity, providing a mechanism for suppressing PDGF-BB-induced VSMC proliferation by direct interactions with c-Myc and its sequestration in the cytoplasm. Overall, our study demonstrated that a previously unrecognized circ-Sirt1/c-Myc/cyclin B1 axis in VSMCs mediates neointimal formation following injury.
