Background： Canopy structure, defined by leaf area index （laI）, fractional vegetation cover （FCover） and fraction of absorbed photosynthetically active radiation （fAPAR）, regulates a wide range of forest functions and ecosystem services. Spatially consistent field-measurements of canopy structure are however lacking, particularly for the tropics. Methods： Here, we introduce the Global laI database： a global dataset of field-based canopy structure measurements spanning tropical forests in four continents （Africa, Asia, Australia and the Americas）. We use these measurements to test for climate dependencies within and across continents, and to test for the potential of anthropogenic disturbance and forest protection to modulate those dependences. Results： Using data collected from 887 tropical forest plots, we show that maximum water deficit, defined across the most arid months of the year, is an important predictor of canopy structure, with all three canopy attributes declining significantly with increasing water deficit. Canopy attributes also increase with minimum temperature, and with the protection of forests according to both active （within protected areas） and passive measures （through topography）. Once protection and continent effects are accounted for, other anthropogenic measures （e.g. human population） do not improve the model. Conclusions： We conclude that canopy structure in the tropics is primarily a consequence of forest adaptation to the maximum water deficits historically experienced within a given region. Climate change, and in particular changes in drought regimes may thus affect forest structure and function, but forest protection may offer some resilience against this effect.

A comprehensive transcriptome assembly for pigeonpea has been developed by analyzing 128.9 million short Illumina GA IIx single end reads, 2.19 million single end FLX/454 reads, and 18 353 Sanger expressed sequenced tags from more than 16 genotypes. The resultant transcriptome assembly, referred to as CcTA v2, comprised 21 434 transcript as- sembly contigs （TACs） with an N50 of 1510 bp, the largest one being -8 kb. Of the 21 434 TACs, 16 622 （77.5%） could be mapped on to the soybean genome build 1.0.9 under fairly stringent alignment parameters. Based on knowledge of intron junctions, 10 009 primer pairs were designed from 5033 TACs for amplifying intron spanning regions （ISRs）. By using in silico mapping of BAC-end-derived SSR loci of pigeonpea on the soybean genome as a reference, putative mapping posi- tions at the chromosome level were predicted for 6284 ISR markers, covering all 11 pigeonpea chromosomes. A subset of 128 ISR markers were analyzed on a set of eight genotypes. While 116 markers were validated, 70 markers showed one to three alleles, with an average of 0.16 polymorphism information content （PIC） value. In summary, the CcTA v2 transcript assembly and ISR markers will serve as a useful resource to accelerate genetic research and breeding applications in pigeonpea.

一项新的整合广告科学机构(IAS)调查发现,营销人员看到了2019年OTT和跨设备领域的巨大的机会。这是IAS调查中第一次将OTT作为一种正式选择,并承认消费者使用媒体的方式发生了变化。另一方面,营销人员仍然关心很多事情,其中包括数据隐私和广告欺诈。但尽管广告欺诈仍居榜首,但今年接受调查的营销人员中,只有不到一半的人(46.2%)表示这是他们最大的担忧,低于去年的61.8%。

最近的模块研发工作已经生产出封装在SP1模组中的快速开关、1200v、13mΩ、增强型SiC JFET半桥模块。这些模块由36mm^2SiC vJFET和23mm^2肖特基管的并联组合而成。在ID=100A条件下,获得2.7mΩ-cm^2的比导通电阻。开关测试采用了标准的双脉冲感性负载电路,在600 v、100A、温度分别为25℃和150℃的条件下,得到了历史最低的总开关损耗——100A、150℃下为1.25mJ。本报告详细介绍测试对开关性能、所采用的栅极驱动电路,以及获得这些结果推荐使用的缓冲器。
