文摘Size reduction of the gas turbines(GT)by reducing the inlet S-shaped diffuser length increases the powerto-weight ratio.It improves the techno-economic features of the GT by lesser fuel consumption.However,this Length reduction of a bare S-shaped diffuser to an aggressive S-shaped diffuser would risk flow separation and performance reduction of the diffuser and the air intake of the GT.The objective of this research is to propose and assess fitted energy promoters(EPs)to enhance the S-shaped diffuser performance by controlling and modifying the flow in the high bending zone of the diffuser.After experimental assessment,the work has been extended to cover more cases by numerical investigations on bare,bare aggressive,and aggressive with energy promoters S-shaped diffusers.Three types of EPs,namely co-rotating low-profile,co-rotating streamline sheet,and trapezoidal submerged EPs were tested with various combinations over a range of Reynolds numbers from 40,000 to 75,000.The respective S-shaped diffusers were simulated by computational fluid dynamics(CFD)using ANSYS software adopting a steady,3D,standard k-εturbulence model to acquire the details of the flow structure,which cannot be visualized in the experiment.The diffuser performance has been evaluated by the performance indicators of static pressure recovery coefficient,total pressure loss coefficient,and distortion coefficient(DC(45°)).The enhancements in the static pressure recovery of the S-shaped aggressive diffuser with energy promoters are 19.5%,22.2%,and 24.5%with EPs at planes 3,4 and 5,respectively,compared to the aggressive bare diffuser.In addition,the installation of the EPs resulted in a DC(45°)reduction at the outlet plane of the diffuser of about 43%at Re=40,000.The enhancements in the performance parameters confirm that aggravating the internal flow eliminates the flow separation and enhances the GT intake efficiency.

文摘The proper flowering time of rose(Rosa hybrida)is vital for the market value of this horticultural crop,but the mechanism regulating this trait is largely unclear.Here,we found that the transcription factor SQUAMOSA PROMOTER BINDING PROTEIN-LIKE4(RhSPL4)positively regulates flowering time in rose.Transient silencing or overexpression transgenic rose plants of RhSPL4 exhibited delayed or early flowering,respectively.Analysis of transcriptome data from transgenic lines overexpressing RhSPL4 compared to the wild type indicated that differentially expressed genes were significantly enriched in the circadian rhythm pathway.Among the proteins encoded by these genes,RhSPL4 binds to the promoter of PSEUDO-RESPONSE REGULATOR 5-LIKE(RhPRR5L),as revealed in yeast one-hybrid,dual-Luciferase/Renilla luciferase reporter,chromatin immunoprecipitation-quantitative PCR and electrophoretic mobility shift assay.Furthermore,RhSPL4 specifically binds to the478 to441 bp region of the RhPRR5L promoter and activates its transcription.The silencing of RhPRR5L delayed flowering time in rose,resembling the phenotype of RhSPL4-silenced plants.Together,these results indicate that the RhSPL4-RhPRR5L module positively regulates flowering time in rose,laying the foundation for the genetic improvement of flowering time in this important horticultural crop.

文摘Intracerebral hemorrhage(ICH) is a significant and growing threat to human health,with increasing incidence.Promoting blood circulation and removing blood stasis therapy(PBCRBS),a Traditional Chinese Medicine therapy,can be an adjuvant therapy to benefit patients with ICH by improving clinical efficacy.However,in theory,using PBCRBS to treat ICH carries the risk of hematoma enlargement and rebleeding,which has led to controversy over its application in ICH treatment.To demonstrate the effectiveness and safety of PBCRBS in treating ICH,this review first analyzes the pathological and physiological basis of ICH and secondly,the cascade of response after ICH and the involvement of cytokines and signaling pathways in this process.Finally,experimental and clinical studies on the treatment of ICH with PBCRBS over the past decade were retrieved from the Pub Med and China National Knowledge Infrastructure databases,and the content of these studies was used to summarize commonly used herbs with PBCRBS effects and their mechanisms of action.Through analysis,hypertension has been identified as the most common cause of ICH.Heme,interleukin,reactive oxygen species,coagulation promoting particles and other induced mass effects,inflammation,oxidative stress,and coagulation cascade reactions lead to brain damage following ICH.This review includes 56 experimental studies and 83 clinical studies summarizing 28 commonly used herbs,demonstrating the positive impact of PBCRBS as an adjuvant therapy for ICH.In summary,PBCRBS appears effective and safe for treating ICH.

文摘Asian cultivated rice is one of the most important cereal crops globally,feeding approximately 50%of the world's population.Increasing rice nitrogen use efficiency(NUE)is crucial for achieving high yields with low nitrogen inputs(Xu et al.,2012;Hu et al.,2023).However,modern cultivars are typically bred for high yields through excessive nitrogen fertilizer use,leading to the loss of beneficial alleles associated with high NUE during the breeding process(Wang and Peng,2017;Hu et al.,2023).Genetic improvement for high NUE should be a key strategy in breeding“Green Super Rice”(GSR)(Yu et al.,2021)and water-saving and drought-resistance rice(WDR)(Luo,2010;Xia et al.,2022)for sustainable agriculture.Asian cultivated rice is highly diverse and harbors vital genetic variants essential for adaptation to different environments(Wing et al.,2018).

文摘Sleep disorders,particularly insomnia,have emerged as a critical public health challenge,with the situation worsened by the coronavirus disease-2019 pandemic.Insomnia symptoms,which affected up to 45%of the population during this period,highlight the urgent need to understand the mechanisms linking sleep disturbances to mental health outcomes.Recent findings suggest that cognitive failures,such as memory lapses and attentional deficits,mediate the relationship between insomnia and emotional disorders such as anxiety and depression.The role of personality traits,particularly neuroticism,adds further complexity,as it may either exacerbate or buffer these effects under specific conditions.This review explores the study by Li et al,which offers valuable insights into the cognitive-emotional pathways influenced by sleep disturbances.The study makes significant contributions by identifying key cognitive mechanisms and proposing the dual role of neuroticism in shaping emotional outcomes.To advance these findings,this letter advocates for future longitudinal research and the integration of targeted interventions,such as cognitive-behavioral therapy for insomnia,into public health frameworks.By addressing insomnia-induced cognitive dysfunction,these strategies can enhance emotional regulation and foster resilience,particularly in vulnerable populations facing the mental health impacts of the pandemic.
