We report the observation of a light-induced subpicosecond phase transition in antiferromagnetic Dirac semimetal EuAgAs, achieved through ultrafast optical excitation. Using spectroscopy, we probe nonequilibrium carrier dynamics, discovering distinct fluence-dependent responses and paramagnetic states, revealing possible magnetic order-driven between different topological states. Our results demonstrate that with its highly tunable structure, possibly offers unique platform for exploring...

Due to explosive growth of online video content in mobile wireless networks, in-network caching is becoming increasingly important improve the end-user experience and reduce Internet access cost for network operators. However, a difficult problem due very large number videos requests,limited capacity nodes, limited bandwidth links. Existing solutions that rely on static configurations average request arrival rates are insufficient handle dynamic patterns effectively. In this paper, we...
2006-2007年对东太湖网围养殖区及航道水生植物种群结构和水环境状况进行了调查.结果表明:采样区内共有水生植物10种,其中沉水植物6种﹑浮叶植物3种﹑漂浮植物1种;养殖区植物种类较单一,耐污染、再生能力强以及水质净化能力好的金鱼藻﹑狐尾藻和伊乐藻在养殖区呈优势种分布;航道和敞水区优势种类为苦草和马来眼子菜.从水生植物生物量变化来看,9月生物量最高,平均为2882.4±748.8g/m<sup>2</sup>;养殖区水生植物生物量高于航道和敞水区,两个网区平均可达1251.2±1012.7g/m<sup>2</sup>、993.9±968.6g/m<sup>2</sup>.水生植物与水环境相互关系来看,温度、透明度和pH等水体物理环境因子对水生植物季节生长和光合作用具有重要影响;水生植物具有吸收水体氮磷营养盐和抑制藻类生长的作用,从而改善了东太湖水质,同时植物季节性生长以及空间分布差异也影响水质时空差异.;The aquatic macrophytes and water environments in the enclosure aquaculture area...
Video traffic is becoming the dominant form of over mobile networks, challenging ongoing standardization and deployment Next generation networks (4G). Currently, as mainstream design evolution to 4G, LTE provide high data-rate communication tunnels between users Internet. However, this generic tunneling introduces at least 3 external hops for any request network, which results in latency well operating expense, especially video with bandwidth requirement. In work, we propose EPCache, a novel...
Layered tellurides have been extensively studied as a platform for investigating the Fermi surface (FS) nesting-driven charge density wave (CDW) states. ${\mathrm{EuTe}}_{4}$, one of quasi-two-dimensional binary rare-earth tetratelluride CDW compounds with unconventional hysteretic transition, is currently receiving much attention. Here, modulation vector, momentum, and temperature dependence gaps in ${\mathrm{EuTe}}_{4}$ are investigated using angle-resolved photoemission spectroscopy. Our...

The research shows that there is long-term equilibrium both have interactivity means promotes...
Apple tree productivity is influenced by the quantity of water and nutrients that are supplied during planting. To enhance resource utilization efficiency optimize yields, a suitable strategy for supplying nitrogen must be established. A field experiment was conducted using randomized block group design on five-year-old apple trees in Ningxia, with two irrigation lower limit levels (55%FC (W1) 75%FC (W2)) four N application (0 (N1), 120 (N2), 240 (N3), 360 (N4) kg·ha
This article studies how the allocation structure of bank credit capital between state-owned and private enterprises government environmental expenditures affect pollution in China. The present literature argues that may play an important role quality improvement. However, these rarely consider State-owned (SOEs) enterprises; addition, they overlook interaction effects expenditures. Based on these, we put forward three hypotheses. Moreover, study applies relevant spatial data for 2011–2017...

利用以水葫芦为代表的水生植物进行水体生态治理,具有环保、生态和可持续发展的优点.然而,在外源和内源污染尚未完全控制的情况下,夏季蓝藻水华仍然会频繁暴发.系统研究水生植物对藻华聚集后形成的逆境环境下的生理适应机制可为减轻藻华聚集的不良影响、充分发挥水生植物的水体净化功能发挥重要作用.以水葫芦为代表,采用模拟实验,研究在高温阶段(水温>25℃)、水华聚集下对水葫芦关键酶活性的影响及其环境效应,以揭示蓝藻水华聚集后引起的浅水生态系统中水生植物消亡的深层机理.结果表明,藻华聚集会很快消耗掉水生植物根区内的溶解氧,水体呈现缺氧状态(溶解氧<0.2mg/L);植物根区内氧化还原电位值出现明显下降,实验进行1d后低于-100mV,实验结束时达-199.9mV,水体呈现强还原环境.植物叶片中丙二醛(MDA)、超氧化物歧化酶(SOD)、过氧化物酶(POD)含量呈现快速增加的变化趋势,至实验结束时添加120g/L的处理组中其含量分别为2.17μmol/g(FW)、266.497U/g、1988.60U/(g·min),而叶片中过氧化氢酶(CAT)呈现快速下降的趋势,至实验结束时其含量为6.09U/(...
