The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QCD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QCD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

断流术是临床常用的治疗门脉高压上消化道出血的术式.其优点是止血确切且对肝功能影响较小,然而由于术后血液高凝状态以及血流动力学的变化,门静脉血栓(portal vein thrombosis,PVT)的发生率大大增加,引起严重并发症.超声、CT、核磁共振成像是临床常用的诊断PVT的方法 .确诊后可通过抗凝、介入、手术等方法给予有效控制及治疗.因为PVT多数出现在断流术围手术期,而且治疗效果局限,所以围手术期PVT的预防显得尤为重要.术前给予抗凝药物预防PVT形成,术中防止对门静脉系统血管内皮损伤,减少脾静脉盲端的形成,稳定术后门静脉的血流动力学.术后常规彩超复查,早期诊断,早期治疗.

【目的】研究葡萄品种的抗性对于绿盲蝽Apolygus lucorum综合防控策略的制定具有重要意义。本研究检测了不同葡萄品种对绿盲蝽的抗性水平,分析了叶片中可溶性蛋白、可溶性糖和叶绿素含量与其对绿盲蝽抗性的关系,以明确不同葡萄品种对绿盲蝽的抗性机理。【方法】以9个葡萄品种(巨峰、玫瑰香、红地球、红宝石、藤稔、赤霞珠、蛇龙珠、霞多丽和品丽珠)为材料,通过连续3年的田间抗性鉴定确定这些葡萄品种对绿盲蝽的抗性水平;分别采用考马斯亮蓝法、蒽酮比色法和乙醇提取法测定不同葡萄品种叶片中可溶性蛋白、可溶性糖和叶绿素的含量,并通过线性回归法分析这些物质含量与葡萄对绿盲蝽抗性的关系。【结果】不同葡萄品种对绿盲蝽的抗性水平不同,按抗性指数从小到大依次为红地球、玫瑰香、巨峰、赤霞珠、品丽珠、红宝石、蛇龙珠、藤稔和霞多丽;不同葡萄品种叶片中可溶性蛋白、可溶性糖和叶绿素含量存在差异;可溶性蛋白和叶绿素含量与抗性指数之间没有显著相关性,而可溶性糖含量与抗性指数之间存在显著负相关(P<0.05)。【结论】不同葡萄品种对绿盲蝽的抗性存在显著差异,藤稔和霞多丽对绿盲蝽具有较高抗性,而红地球、玫瑰香和巨峰则较为敏感,该差异可能与葡萄叶片中可溶性糖的含量有关。
