Carbon isotope discrimination of arctic and boreal biomes inferred from remote atmospheric measurements and a biosphere-atmosphere model [PDF]
Estimating discrimination against ^(13)C during photosynthesis at landscape, regional, and biome scales is difficult because of large-scale variability in plant stress, vegetation composition, and photosynthetic pathway. Here we present estimates of ^(13)

The Costs and Benefits of Forensics [PDF]
Supreme Court Justice Louis Brandeis famously wrote that states can be laboratories for experimentation in law and policy. Disappointingly, however, the actual laboratories that states and local governments run are not a home for experimentation.

针对特高压直流输电系统接线方式从单极大地回线转为金属回线时,MRTB并联震荡装置是否出现故障,提出了一种基于电流分析的MRTB并联震荡装置的在线故障诊断方法。该方法首先通过在MRTB过零震荡装置进线侧和出线侧划定计算电流的闭合面,并在闭合面上运用基尔霍夫电流定律(KCL),设计出一种计算MRTB并联震荡装置回路电流的方法,然后根据计算所得的MRTB并联震荡装置两侧电流特征,对并联谐振装置是否故障与故障类型进行诊断。最后,在±800 kV楚穗特高压直流极Ⅱ大地回线转为金属回线的2个实例中进行验证 ...

Comparative genomics highlights the unique biology of Methanomassiliicoccales, a Thermoplasmatales-related seventh order of methanogenic archaea that encodes pyrrolysine [PDF]
BACKGROUND: A seventh order of methanogens, the Methanomassiliicoccales, has been identified in diverse anaerobic environments including the gastrointestinal tracts (GIT) of humans and other animals and may contribute significantly to methane emission ...

在特高压换流站中,中性母线避雷器组以及转换开关避雷器组中并联柱数多,导致这两处位置的避雷器组故障频发,继而很大概率导致直流系统闭锁。目前的避雷器用脱离器以及压力释放装置等保护措施无法为解决避雷器故障会导致直流系统闭锁的问题,因此提出一种多柱并联避雷器组熔断式故障退出措施。在避雷器单元筒内部每一柱氧化锌电阻上串联一个特性匹配的熔断器,一旦某一柱的电阻片吸收能量过多出现击穿、电流集中灌入时,该柱熔断器在保护系统发出闭锁指令前快速熔断并隔离该故障柱,保证避雷器组剩余部分仍可正常运行 ...
