为明确不同鲜食玉米品种对鞘腐病抗性、鞘腐病在玉米不同生态位叶鞘的分布特征及生防菌剂对病害的防治效果,测定了15个福建省主推玉米品种对鞘腐病的田间抗性,选用6个不同抗性水平的玉米品种为研究对象,于乳熟期调查了不同玉米品种各叶鞘的病情及9种生防菌剂处理对“上品”关键叶鞘病害的控制效果。结果表明,参试玉米对鞘腐病表现中抗、中感和感病的品种分别有5个、7个和3个。在屏南自然发病试验地和福州人工辅助接种试验地,6个玉米品种“上品(感病)”、“京科糯2000(感病)”、“天贵糯932(感病)”、“农科368(中感)”、“泰鲜甜2号(中抗)”、“闽甜986(中抗)”穗上第1叶鞘至穗下第3叶鞘平均病情指数分别为35.05、44.75、45.54和39.78,而其他叶鞘平均病情指数介于6.67~28.77之间。在屏南试验地有4个玉米品种(上品和天贵糯932除外)和福州试验地有6个玉米品种病情严重度在各生态位叶鞘上均呈显著正态性分布(P>0.05)。施用生防菌剂能明显抑制感病品种“上品”鞘腐病病情,稀释20、50倍的8×10^(9) CFU/mL枯草芽胞杆菌T122F发酵液和5×10^(9) CFU/mL解淀粉芽胞杆菌NJ-1发酵液对病害的防效分别为46.37%、44.78%和44.03%、41.06%,稀释500倍的400亿芽胞/g枯草芽胞杆菌水溶性粉剂、1000亿芽胞/g解淀粉芽胞杆菌水溶性粉剂和30亿芽胞/g甲基营养型芽胞杆菌可湿性粉剂的防病效果分别达44.25%、36.81%和46.26%,比150μg/mL的25%吡唑醚菌酯乳油防效(59.50%)和12.5%氟环唑悬浮剂的防效(54.82%)略低。表明利用生防菌剂预防玉米鞘腐病具有较好的应用前景,本研究结果为鲜食玉米病害绿色防控提供科学依据。

UAV cooperative control has been applied in many complex UAV communication networks. It remains challenging to develop UAV cooperative coverage and UAV energy-efficient communication technology. In this paper, we investigate current works about UAV coverage problem and propose a multi-UAV coverage model based on energy-efficient communication. The proposed model is decomposed into two steps: coverage maximization and power control, both are proved to be exact potential games(EPG) and have Nash equilibrium(NE) points. Then the multi-UAV energy-efficient coverage deployment algorithm based on spatial adaptive play(MUECD-SAP) is adopted to perform coverage maximization and power control, which guarantees optimal energy-efficient coverage deployment. Finally, simulation results show the effectiveness of our proposed approach, and confirm the reliability of proposed model.

Invasive genetic screening of pre-implantation embryos via biopsied trophectoderm(TE)cells has been in use for more than 20 years,while its benefits in selecting euploid embryos remain *** advances in the ability to process embryonic cell-free DNA(cfDNA)from blastocoel fluid(BF)and spent culture media(SCM)of blastocysts in a manner similar to that of a biopsied TE sample provide a potential alternative holding great promise for obtaining cytogenetic information of the embryos without intrusive biopsy of traditional biopsy-based pre-implantation genetic testing(PGT).Several studies have reported even higher diagnostic accuracy in non-invasive PGT(ni-PGT)than conventional ***,there are still several technical challenges to be overcome before ni-PGT can be accepted as a reliable genomic information source of *** this review,we have summarized the emergence and current state of ni-PGT,and discussed our own perspectives on their limitations and future *** is still a long way to go before truly wide clinical application of ni-PGT.

In the present study, we evaluated the antitumor, anti-tyrosinase, anti-pancreatic lipase, antibacterial, antifungal, and anti-α-glycosidase activities for all or a subset of 20 known compounds. They included 8 phenyl benzoates, 10 benzophenones, and 2 xanthones. Phenyl benzoate compounds 1–8 did not exhibit evident antitumor activity, which was consistent with existing theories. Compounds 16, 17, and 18 exhibited moderate anti-tyrosinase activity. In addition, compounds 11 and 18 exhibited moderate inhibitory activity against Candida albicans, and compound 20 exhibited stronger anti-α-glycosidase activity than quercetin, with an IC_(50)of approximately 2.45 μM. These results demonstrated that compounds 11, 16–18, and 20 were promising leads for further structural modification.

基于永定河流域内1957~2010年降雨、蒸发和径流数据,采用Mann-Kendall趋势检验法结合距平序列变化情况分析蒸发能力、降雨和径流的变化趋势;运用Mann-Kendall突变检验法、Hurst系数法分析流域径流序列的突变年及对应的突变程度;在此基础上以径流突变年为界划分基准期和变化期,采用弹性系数法定量分析气候变化和人类活动对径流的影响,并简要分析其原因。结果表明:流域蒸发能力呈现上升趋势,降雨和径流呈现递减趋势;径流序列突变点发生在1984年,突变程度属中度变异;永定河流域由气候变化引起的径流变化率为28%,而由于人类活动引起的径流变化率为72%,可见人类活动是影响永定河流域径流变化的主要驱动因素。
