The first search for the doubly heavyΩ^(0)_(bc)baryon and a search for the E^(0)_(bc)baryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb^(-1).The baryons are reconstructed via their decays to Λ^(+)_(c)π^(-)and E^(+)_(c)π^(-).No significant excess is fbund for invariant masses between 6700 and 7300 MeV/c^(2),in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on the ratio of the Ω^(0)_(bc)and E^(0)_(bc)production cross-section times the branching fraction to Λ^(+)_(c)π^(-)(E^(+)_(c)π^(-))relative to that of the Λ^(0)_(b)(E^(0)_(b))baryon,for different lifetime hypotheses,at 95%confidence *** upper limits range from 0.5 x 10^(-4)to 2.5 x 10^(-4)for theΩ^(0)_(bc)→Λ^(+)_(c)π^(-)(E^(0)_(bc)→Λ^(+)_(c)π^(-))decay,and from 1.4x 10^(-3)to 6.9 x 10^(-3)for theΩ^(0)_(bc)→E^(+)_(c)π^(-)(E^(0)_(bc)→E^(+)_(c)π^(-))decay,depending on the considered mass and lifetime of theΩ^(0)_(bc)(E^(0)_(bc))baryon.

Phenotypic Diversity of Jatropha curcas L. from Diverse Origins

引用

Journal of Agricultural science and Technology 2011年第2期5卷 215-219页

作者： F. L. Zapico s. K. Nival C. H. Aguilar M. N. Eroy science Department College of Natural Sciences and Mathematics Mindanao State University Fatima General Santos City 9500Philippines Philippine Coconut Authority Region 11 Bago Oshiro Tugbok District Davao City 8000 Philippines

The study was conducted to assess intraspecific variation/interrelationships and to determine the association of geographical distribution and phenotypic diversity in the Jatropha curcas accessions studied. Ex situ morphological characterization of 13 Jatropha curcas genotypes from various sources was undertaken using 21 quantitative traits. The generated data was subjected to two phenetic analysis methods (principal components analysis and cluster analysis). Principal Components Analysis (PCA) reduced the collected data to 5 principal components that cumulatively explained 88.81% of total variance. PCA also subdivided the Jatropha provenances into distinct groups on the basis of height. The two clustering mechanisms, Average Linkage-Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and Centroid Method (UPGMC), divided the provenances into two major groups and revealed the divergence of Tubao-Philbio from the rest of the provenances. However, the study failed to adequately establish a relationship between spatial dispersal and phenotypic divergence in the Jatropha genotypes implying possible genetic homogeneity for the accessions studied. screening for more quantitative traits and the use of more advanced molecular marker technologies are therefore recommended for a more accurate estimation of genetic diversity in Jatropha.

背景:西班牙四个城市9 家公共卫生治疗中心。目的:比较2 个月利福平+吡嗪酰胺(2RZ)与6 个月异烟肼(6H)治疗潜伏结核感染(LTBI),评估其效益及安全性。设计:对传染性肺结核病人的HIV(-)接触者进行多中心的前瞻性随机比较研究。结果:352 例中接受6H 者199 例,2RZ 者153 例;6H 组及2RZ 组治疗完成率各为73%及71%(P=0.73)。因肝毒性反应(AsT 或ALT>5 倍正常上限值(ULN))而中断治疗者,2RZ 组为10%,6H 组为2.5%(P=0.007)。2RZ 组肝毒性反应高于期望发生率,因而未到期即终止了研究。停止治疗后肝功能均恢复正常。结论是RZ 方案只应用于不适用其它治疗方案者,且需有强化观察肝功能的条件。
