文摘Cyprus has an extensive record in grape production and winemaking.Grapevine is essential for the economic and environmental sustainability of the agricultural sector,as it is in other Mediterranean regions.Intensive agriculture can overuse and exhaust natural resources,including soil and water.The current study evaluated how conservation strategies,including no tillage and semi-tillage(as a variation of strip tillage),affected grapevine growth and grape quality when compared to conventional tillage application.Two cultivars were used:Chardonnay and Maratheftiko(indigenous).Soil pH decreased,and EC increased after tillage applications,in both vineyards.Tillage lowered soil N levels through mineralization,but the vineyard with Maratheftiko cultivar had higher soil N and K levels than the vineyard with Chardonnay cultivar.No tillage reduced yield in Chardonnay;however,semi-tillage enhanced yield in Maratheftiko.There were no major changes in plant physiology,even though Maratheftiko had less variation in stomatal conductance values under the various tillage practices than Chardonnay.Tillage enhanced N and K content in Chardonnay vines during flowering,and increased N in Maratheftiko.Total phenols and antioxidant status of leaves varied,with tillage stimulating them,especially at the harvest stage.Furthermore,tillage raised grape juice total soluble solids,pH,and total phenols in both cultivars,while anthocyanins and tannins content were increased in Maratheftiko under no tillage.The results of this study may aid in the development of cultivation strategies to enable viticulture to address various environmental challenges due to climate change.

文摘With the expanding applications of unmanned aerial vehicles(UAVs),precise flight evaluation has emerged as a critical enabler for efficient path planning,directly impacting operational performance and safety.Traditional path planning algorithms typically combine Dubins curves with local optimization to minimize trajectory length under 3D spatial constraints.However,these methods often overlook the correlation between pilot control quality and UAV flight dynamics,limiting their adaptability in complex scenarios.In this paper,we propose an intelligent flight evaluation model specifically designed to enhancemulti-waypoint trajectory optimization algorithms.Our model leverages a decision tree to integrate attitude parameters and trajectory matching metrics,establishing a quantitative link between pilot control quality and UAV flight states.Experimental results demonstrate that the proposed model not only accurately assesses pilot performance across diverse skill levels but also improves the optimality of generated trajectories.When integrated with our path planning algorithm,it efficiently produces optimal trajectories while strictly adhering to UAV flight constraints.This integrated framework highlights significant potential for real-time UAV training,performance assessment,and adaptive mission planning applications.

文摘In the evolving global economy,China’s Outward Foreign Direct Investment(OFDI)holds increasing significance,specially within the context of the Belt and Road Initiative(BRI).Despite earlier studies have acknowledged the role of governance quality in at-tracting Chinese OFDI,their explanatory capacity regarding human development has not received sufficient attention.This study ad-dresses this gap,investigating the relationship between Chinese OFDI and human development,emphasizing the governance quality’s moderating role.Using data from 122 BRI countries from 2004 to 2021,we employed the Panel Corrected Standard Error model through Prais-Winsten regression,complimented by robustness check via the Spatial Durbin Model.Our analysis revealed a significant positive relationship between Chinese OFDI and human development in BRI countries,indicating that Chinese investments act as cata-lysts for improved well-being.More importantly,governance quality plays a vital role in shaping this relationship,revealing that effect-ive governance enhanced the human development outcomes of OFDI.Post-hoc analysis of governance indicators,both as a composite index and individual dimensions,supported this finding.Regional heterogeneity analysis further showed that Chinese OFDI has stronger effects on Human Development Index(HDI)in Asia and Africa compared to Europe,Latin America,and Oceania.However,the moder-ating effect of governance quality seemed more prominent in Oceania and Latin America,indicating its role in fostering the benefits of Chinese investments in these regions.These findings hold implications for academia and policy,emphasizing the need for transparent,accountable,and effective governance to drive sustainable and inclusive human development within the BRI framework.

文摘Skeletal muscle health and function are essential determinants of metabolic health,physical performance,and overall quality of life.The quality of skeletal muscle is heavily dependent on the complex mitochondrial reticulum that contributes toward its unique adaptability.It is now recognized that mitochondrial perturbations can activate various innate immune pathways,such as the nucleotide-binding oligomerization domain(NOD)-like receptor protein 3(NLRP3)inflammasome complex by propagating inflammatory signaling in response to damage-associated molecular patterns(DAMPs).The NLRP3 inflammasome is a multimeric protein complex and is a prominent regulator of innate immunity and cell death by mediating the activation of caspase-1,pro-inflammatory cytokines interleukin-1βand interleukin-18 and pro-pyroptotic protein gasdermin-D.While several studies have begun to demonstrate the relationship between various mitochondrial DAMPs(mtDAMPs)and NLRP3 inflammasome activation,the influence of various metabolic states on the production of these DAMPs and subsequent inflammatory profile remains poorly understood.This narrative review aimed to address this by highlighting the effects of skeletal muscle use and disuse on mitochondrial quality mechanisms including mitochondrial biogenesis,fusion,fission and mitophagy.Secondly,this review summarized the impact of alterations in mitochondrial quality control mechanisms following muscle denervation,aging,and exercise training in relation to NLRP3 inflammasome activation.By consolidating the current body of literature,this work aimed to further the understanding of innate immune signaling within skeletal muscle,which can highlight areas for future research and therapeutic strategies to regulate NLRP3 inflammasome activation during divergent metabolic conditions.
