This study,taking Shaanxi Province as an example,systematically analyzed the coupling and coordination relationship between the digital economy and high-quality agricultural development from 2015 to 2024 by comprehensively employing the coupling coordination model and the entropy method.The findings reveal that both the digital economy and high-quality agricultural development indices in Shaanxi Province exhibit a consistent upward trend.The level of coupling coordination has progressively transitioned from a low degree of coupling to a coordinated development stage,establishing a virtuous interactive pattern characterized by"digital enabling agriculture"and"agriculture driving innovation".The driving force behind this coupling primarily stems from the synergistic interplay of a triple mechanism involving"policy guidance,technological breakthroughs,and industrial support".However,structural imbalances persist across regions and agricultural segments,chiefly manifested as the digital divide between the Guanzhong Plain and the Northern(Shaanbei)and Southern(Shaannan)regions,alongside insufficient integration depth of digital technologies in the latter stages of the agricultural industry chain.To address these challenges,the study proposes recommendations including building a"tri-chain integrated"technological ecosystem,optimizing a differentiated policy support mechanism,and implementing regionally targeted strategies.These measures aim to foster deep integration of the digital economy with the entire agricultural value chain across diverse regions,offering pathways for western agricultural provinces to bridge the digital divide and achieve rural revitalization. 展开更多

This study examines the methods to plan the development of offshore oilfields over the years,which are used to support the decision-making on the development of offshore oilfields.About 100 papers are analysed and categorised into different groups of main early-stage decisions.The present study stands in contrast to the contributions of the operations research and system engineering review articles,on the one hand,and the petroleum engineering review articles,on the other.This is because it does not focus on one methodological approach,nor does it limit the literature analysis by offshore oilfield characteristics.Consequently,the present analysis may offer valuable insights,for instance,by identifying environmental planning decisions as a recent yet highly significant concern that is currently being imposed on decision-making process.Thus,it is evident that the incorporation of safety criteria within the technical-economic decision-making process for the design of production systems would be a crucial requirement at development phase. 展开更多

County-to-district conversion(CDC) has restructured the pattern of urban-rural development and influenced the allocation of resources by local governments as well as the urbanization process.However,the impact and mechanism of the CDC on China's urban-rural integration development(URID) are not yet clear.Using panel data from 52 county-level cities,districts,and counties in Jiangsu Province of China during 2005–2021,this paper constructed an evaluation system for URID and applied the multi-period difference-in-differences(DID) model to measure the impact of the CDC on URID and identify its primary mechanisms of action.The results demonstrated that the CDC has significantly fostered URID,though with pronounced regional heterogeneity.Specifically,while the CDC facilitated URID in the southern and central Jiangsu Province—regions characterized by high socio-economic development—it exerted a less significant impact in the comparatively underdeveloped northern Jiangsu Province.Mechanistically,the implementation of the CDC promotes equal regional development,enhances rural selfdevelopment capacity,improves environmental quality and living standards,and optimizes urban-rural land allocation and transport networks.Ultimately,this study clarifies the role of the CDC in China,provides insights for achieving URID,and offers a reference for other countries pursuing coordinated urban-rural development. 展开更多

The Chinese government’s common prosperity policy has inspired a series of rural development initiatives aimed at reducing income disparities between urban and rural areas.Zhejiang Province was designated as the first demonstration zone in China’s pursuit of common prosperity.To explore the demonstration effect of rural development on narrowing the income gap between urban and rural areas,this study adopts the Theil index to measure urban-rural income disparity levels and explores spatial evolution patterns of the income disparity in 52 counties of Zhejiang Province,China from 2011 to 2020.The spatial Durbin model is also used to investigate the impact of rural development on the urban-rural income disparity.The results show that:1)Urban-rural income disparities have gradually narrowed.Moreover,income disparities across the province are spatially clustered from north to south.Narrowing the gap between mountainous and non-mountainous counties is imperative for resolving these spatial imbalances in the short term.2)Rural development reduces urban-rural income disparity levels and generates economic and technological spillover effects,as evidenced by the phenomenon where development in one county leads to reduced income disparities in neighboring counties.3)The technological innovation enhances the co-development of rural industries through technological diffusion effects,further strengthening rural development.Finally,enhancing the ecological environment synergizes with rural development to reduce urban-rural income disparities.The research results provide policy implications for narrowing the urban-rural income disparity and promoting common prosperity. 展开更多

The promotion of rural revitalization within the ecological conservation areas(“ECAs”) requires a careful balance between ecological protection and economic development and should be guided by the principle of ecological priority. The cultivation of rural “Local Specialty Products”(“LSPs”) under a green-development framework aligns with the functional positioning of these areas, drives the revitalization of rural industries, and constitutes a fundamental strategy for addressing the unique challenges they face. Although ECAs possess inherent advantages in terms of developing LSPs, they are also confronted by multiple constraints. Accordingly, we propose development objectives that emphasize(a) driving rural industrial prosperity,(b) enhancing the appeal of agricultural heritage, and(c) ensuring inclusive prosperity in the farming communities. In selecting pathways for growth, priority should be given to improving the quality of products, fostering distinctiveness of the technologies, nurturing cultural identities, and upholding the principle of common prosperity. From a policy standpoint, the development of rural LSPs should be recognized as a key lever for advancing the comprehensiveness of rural revitalization in the ECAs. We recommend a set of supportive measures—namely, reinforcing the guidance for spatial planning, integrating the consolidation of factor inputs, and ensuring the robustness of organizational guarantees—to facilitate the high-quality development of LSPs in these areas. 展开更多

Motor neuron diseases are sporadic or inherited fatal neurodegenerative conditions.They selectively affect the upper and/or lower motor neurons in the brain and spinal cord and feature a slow onset and a subacute course contingent upon the site of damage.The main types include amyotrophic lateral sclerosis,progressive muscular atrophy,primary lateral sclerosis,and progressive bulbar palsy,the pathological processes of which are largely identical,with the main disparity lying in the location of the lesions.Amyotrophic lateral sclerosis is the representative condition in this group of diseases,while other types are its variants.Hence,this article mainly focuses on the advancements and challenges in drug research for amyotrophic lateral sclerosis but also briefly addresses several other important degenerative motor neuron diseases.Although the precise pathogenesis remains elusive,recent advancements have shed light on various theories,including gene mutation,excitatory amino acid toxicity,autoimmunology,and neurotrophic factors.The US Food and Drug Administration has approved four drugs for use in delaying the progression of amyotrophic lateral sclerosis:riluzole,edaravone,AMX0035,and tofersen,with the latter being the most recent to receive approval.However,following several phaseⅢtrials that failed to yield favorable outcomes,AMX0035 has been voluntarily withdrawn from both the US and Canadian markets.This article presents a comprehensive summary of drug trials primarily completed between January 1,2023,and June 30,2024,based on data sourced from clinicaltrials.gov.Among these trials,five are currently in phaseⅠ,seventeen are in phaseⅡ,and eleven are undergoing phaseⅢevaluation.Notably,24 clinical trials are now investigating potential disease-modifying therapy drugs,accounting for the majority of the drugs included in this review.Some promising drugs being investigated in preclinical studies,such as ATH-1105,are included in our analysis,and another review in frontiers in gene therapy and immunotherapy has demonstrated their therapeutic potential for motor neuron diseases.This article was written to be an overview of research trends and treatment prospects related to motor neuron disease drugs,with the aim of highlighting the latest potentialities for clinical therapy. 展开更多

The leucine-rich repeat(LRR)protein family is involved in a variety of fundamental metabolic and signaling processes in plants,including growth and defense responses.LRR proteins can be divided into two categories:those containing LRR domains along with other structural elements,which are further subdivided into five groups,LRR receptor-like kinases,LRR receptor-like proteins,nucleotide-binding site LRR proteins,LRR-extensin proteins,and polygalacturonase-inhibiting proteins,and those containing only LRR domains.Functionally,various LRR proteins are primarily involved in plant development and responses to environmental stress.Notably,the LRR protein family plays a central role in signal transduction pathways related to stress adaptation.In this review,we classify and analyze the functions of LRR proteins in plants.While extensive research has been conducted on the roles of LRR proteins in disease resistance signaling,these proteins also play important roles in abiotic stress responses.This review highlights recent advances in understanding how LRR proteins mediate responses to biotic and abiotic stresses.Building upon these insights,further exploration of the roles of LRR proteins in abiotic stress resistance may aid efforts to develop rice varieties with enhanced stress and disease tolerance. 展开更多
