Wheat powdery mildew(Blumeria graminis ***, Bgt) is a disease of increasing importance globally due to the adoption of high yielding varieties and modern sustainable farming *** resistant cultivars is a preferred approach to managing this disease, and novel powdery mildew resistance genes are urgently needed for new cultivar development.A genome-wide association study was performed on a panel of 1292 wheat landraces and historical cultivars using 5011 single nucleotide polymorphism(SNP)*** association panel was evaluated for reactions to three Bgt inoculants, OKS(14)-B-3-1, OKS(14)-C-2-1, and *** disequilibrum(LD) analysis indicated that genome-wide LD decayed to 0.1 at 23 Mb, and population structure analysis revealed seven subgroups in the *** analysis using a mixed linear model(MLM) identified three loci for powdery mildew resistance on chromosome 2 B, designated ***-2BL1,***-2BL2, and *** evaluate the efficacy of GWAS in gene discovery,***-2BL2 was validated using f2 and f2:3 populations derived from PI420646 × *** analysis delimited the powdery mildew resistance gene in PI 420646 to an interval where ***-2BL2 was located, lending credence to the GWAS ***-2BL1 and ***-2BL3, which were associated with four SNPs located at 457.7–461.7 Mb and two SNPs located at 696.6–715.9 Mb in the Chinese Spring reference IWGSC RefSeq v1.0, respectively, are likely novel loci for powdery mildew resistance and can be used in wheat breeding to improve powdery mildew resistance.

Alkali metal ions(M+ = Na+,Li+,K+) co-doped ZnAl2O4:Eu3+(5 mol%)(ZAE) nanopowders(NPs) were prepared via solution combustion route using Mimosa pudica(MP) leaves extract as a fuel. PXRD results of co-doped samples enhance the crystallinity and grain growth. Photoluminescence(PL) of the prepared ZAE and ZAE:M+(M+ = Na+, Li+, K+) NPs shows intense emission peaks in the range of 550-750 nm and ascribed to 5D0→7fJ(J=0-4) transitions of Eu3+ ions, respectively. A 2-fold enhancement in PL intensity was observed in Li+ co-doped samples. The optimized ZnAl2O4:Eu3+(5 mol%), Li+(1 wt%)(ZAEL)NPs were used to visualize LfPs on various porous, semi-porous and non-porous surfaces through robust powder dusting technique. The visualized latent fingerprints(LfPs) reveal well defined level 1-3 ridge characteristics under several tests such as fingerprint aging and fresh water treatment for various time durations. The obtained results clearly evidence that the prepared NPs are quite useful for multifunctional applications such as advanced forensic and solid state lightning.

The Evolving Structure of Multi-Hospital Systems in the US: focus on California

引用

Health 2021年第7期13卷 757-765页

作者： Glenn Melnick June f. O’Leary Sol Price School of Public Policy University of Southern California Los Angeles CA USA

Objectives: Hospital consolidation and the growth of multi-hospital systems are generating media headlines in the US. While there is a growing literature on the role of multi-hospital systems in the US health care system, it is still quite limited. This study helps fill the gap by documenting and describing the structure and evolution of multi-hospital systems in California over a recent 18-year period. Methods: Descriptive analysis of a hospital level longitudinal database covering the period 2002-2019 in California. Results: The total number of hospitals declined by 40 hospitals, from 445 to 405, over the study period and the total number of multi-hospital systems increased substantially from 14 systems in 2002 to 30 systems in 2019. As a result, the number and proportion of all California hospitals that were part of a multi-hospital system grew—from 177 in 2002 to 238 in 2019. By 2019, 59% of all hospitals were part of systems (compared to 40% in 2002). The size distribution of multi-hospital systems in California changed substantially over time. In the early period, larger systems dominated the system landscape. Now, half of all systems have 5 or fewer hospitals compared to 29% in 2002, while the percentage of systems with 25 or more members has declined from 25% to just 7%. Interestingly, the clinical service mix of hospital systems has changed substantially. In 2002, all 14 systems were largely acute care focused. By 2019, less than half of systems had acute care as their only and primary focus. Conclusions: Combined, these findings provide insight into the development, evolution and growing role of hospitals systems in our health care system and identify new areas for further research.

与传统的能源发电投资相比,风电投资具有更大的投资风险。在目前的技术水平下,风电的大力发展离不开国家的政策扶持。无论对风电投资者而言,还是对风电投资政策制定者而言,均迫切需要一个可将风险量化的投资辅助决策工具。基于实物期权理论,文中建立了适用于中国风电投资环境的风电项目投资决策模型。该模型考虑了风电上网电价的不确定性、风电场投资及运行成本、投资政策、投资时机等因素。算例分析表明该模型可为投资者选择合适的投资时机提供决策参考,另外还可作为政策制定者制定合理投资政策的量化分析工具。
