Objective: Plant-based diets have multiple health benefits for cancers;however, little is known about the association between plant-based dietary patterns and esophageal cancer(EC).This study presents an investigation of the prospective associations among three predefined indices of plant-based dietary patterns and the risk of ***: We performed endoscopic screening for 15,709 participants aged 40-69 years from two high-risk areas of China from January 2005 to December 2009 and followed the cohort until December 31, 2022. The overall plant-based diet index(PDI), healthful plant-based diet index(h PDI), and unhealthful plant-based diet index(u PDI), were calculated using survey responses to assess dietary patterns. We applied Cox proportional hazard regression to estimate the multivariable hazard ratios(HRs) and 95% confidence intervals(95% CIs) of EC across 3plant-based diet indices and further stratified the analysis by ***: The final study sample included 15,184 participants in the cohort. During a follow-up of 219,365person-years, 176 patients with EC were identified. When the highest quartile was compared with the lowest quartile, the pooled multivariable-adjusted HR of EC was 0.50(95% CI, 0.32-0.77) for h PDI. In addition, the HR per 10-point increase in the h PDI score was 0.42(95% CI, 0.27-0.66) for ECs. Conversely, u PDI was positively associated with the risk of EC, and the HR was 1.80(95% CI, 1.16-2.82). The HR per 10-point increase in the u PDI score was 1.90(95% CI, 1.26-2.88) for ECs. The associations between these scores and the risk of EC were consistent in most subgroups. These results remained robust in sensitivity ***: A healthy plant-based dietary pattern was associated with a reduced risk of EC. Emphasizing the healthiness and quality of plant-based diets may be important for preventing the development of EC.

1937年11月初，日军从金山卫登陆后，很快扭转淞沪会战的战局，结果不到20天，即占领太湖南岸的吴兴。在此后7年半的岁月中，日军凭借武力优势，控制大部平原地带，中方则退守于浙西，并在军事、政治、经济、文化等各个领域持续进行斗争。在这一时期，国民党基层党工冯千乘亲身经历并见证了历史，他留下的《抗战八年的吴兴》《八载苦难记戴山》等文字记录，不仅能够充实抗战史的细节，而且有助于拓宽抗战史的研究视野。根据其所述之敌我态势发展，抗战时期的吴兴可分为县城沦陷前后（1937年7月上旬至1938年12月）、正规军驻防（1939年1月至1942年8月）、“忠义救国军”与挺进队驻防（1942年8月至1945年1月）及新四军苏浙军区发展（1945年2月至1945年10月）四个阶段。

为解决高原机场道面混凝土易收缩开裂和冻融破坏问题,对不同玄武岩纤维和橡胶颗粒掺量混凝土开展了力学性能、早期收缩性及抗冻性能的研究,采用核磁共振和扫描电子显微镜阐释了玄武岩纤维与橡胶颗粒的作用机理,并建立了考虑玄武岩纤维和橡胶颗粒掺量的混凝土早期收缩模型。试验结果表明:同基准混凝土相比,掺0.3%(体积分数,下同)玄武岩纤维与10%(砂的体积取代率,下同)橡胶颗粒混凝土的7和28 d抗折强度分别提高了13.6%、11.8%,7、28 d抗压强度分别提高了26.7%、18.1%,72 h收缩率降低了54.7%,300次冻融循环后质量损失率降低了67.0%,动弹性模量损失率降低了10.4%;玄武岩纤维可抑制混凝土基体微裂缝的萌生扩展,承受部分收缩应力。而弹性体橡胶颗粒的填充、蓄水与引气作用可优化基体孔结构,延缓水分蒸发速率,缓解冻胀压力,使混凝土力学性能和抗冻性提高,早期收缩降低;建立的收缩模型能较好地反映玄武岩纤维-橡胶混凝土早期收缩变化特征。

This paper presents an application of synergy methodology to a multi- objective operational control of reservoirs. This methodology enables a comprehensive consideration of multi-objectives which may be conflicting and non commensurate such as municipal and industrial water supply, flood protection, and hydroelectric power generation etc. On the basis of the synergy theory, a harmony degree model of sub- system was established to describe the coordination magnitude. Combined with information entropy, a harmony degree entropy was proposed to determine the water resources evolvement direction. While implementing the control, an initial scheme for reservoir operation was obtained from simulation first, then control was carried out according to the harmony degree and harmony degree entropy by applying synergy theory. The application of the methodology to reservoir system in the Yellow River was reported in this paper through a case study.

Freshwater reservoirs are regarded as an important anthropogenic source of methane(CH_(4))emissions. The temporal and spatial variability of CH_(4) emissions from different reservoirs results in uncertainty in the estimation of the global CH_(4) budget. In this study, surface water CH_(4) concentrations were measured and diffusive CH_(4) fluxes were estimated via a thin boundary layer model in a temperate river–reservoir system in North China, using spatial(33 sites) and temporal(four seasons) monitoring;the system has experienced intensive aquaculture disturbance. Our results indicated that the dissolved CH_(4) concentration in the reservoir ranged from 0.07 to 0.58 μmol/L, with an annual average of 0.13 ± 0.10 μmol/L, and the diffusive CH_(4) flux across the water–air interface ranged from 0.66 to 3.61 μmol/(m^(2)·hr),with an annual average of 1.67 ± 0.75 μmol/(m^(2)·hr). During the study period, the dissolved CH_(4) concentration was supersaturated and was a net source of atmospheric CH_(4) . Notably,CH_(4) concentration and diffusive flux portrayed large temporal and spatial *** river inflow zone was determined to be a hotspot for CH_(4) emissions, and its flux was significantly higher than that of the tributary and main basin;the CH_(4) flux in autumn was greater than that in other seasons. We also deduced that the CH_(4) concentration/diffusive flux was co-regulated mainly by water temperature, water depth, and water productivity(Chla, trophic status). Our results highlight the importance of considering the spatiotemporal variability of diffusive CH_(4) flux from temperate reservoirs to estimate the CH_(4) budget at regional and global scales.
