These signals travel via the airwaves, satellites, or cable as a continuous stream of electromagnetic energy(like light and radio waves). But this system leaves a lot of room for error. The main problem is that interference can change the voltage of the signal as it travels. This may ...
Usually, arrow thickness indicates the strength of the corresponding chemical pathway. A consistent representation of chemical transformation pathways is based on a conserved property, like the element moles in a closed chemical system. The flux of element A from species j to species k through ...
《朗读者》发布会上，董卿引用了巴金先生书里的一句话：“我们不是单靠吃米活着”。希望在吃米、吃饭、吃肉之外，能够给予大家一些心灵的，精神的抚慰，这也是我们媒体人最大的成就感，这就是《朗读者》的制作目的。这告诉我们
As people's energy demand increases, an increasing use of renewable resources is needed to mitigate the effects of global warming. These sources (such as solar and wind) are intermittent, thus energy storage is crucial for their widespre... M Bianchini,J Wang,R Clément,... 被引量: 0发表...
An article in the US journal Health Affairs investigating the number of Canadians who come here to avoid these waits found the number so small that it asked, "A tip with no iceberg" Britain spends only 40% as much as we do on healthcare. But according to the Journal of the American ...
However, the results in the first and second blocks are fairly similar, which indicates that the results are reasonably stable. Overall, we see a substantial improvement in the third block compared to the second, suggesting that the U-Nets benefit from more training data. We also notice that ...
Noteworthy, too, are the measures of yield, which indicate the fund’s ability to generate income.8There are several types: Distribution yield: This is based on the income distributed by the fund in the most recent annualized period. It indicates the income generated by the fund but is also...
b Synchrotron PXRD patterns of PATCnC and CAF-2. c IR traces of 4,4′,4″,4‴-methanetetrayltetrabenzoic acid (MTAB) and CAF-2 which indicates the continued presence of the amide bond. The presence of the C = O stretches are indicated in the figure. d, e 15N and 13C CP ...
All living organisms exist in an environment teeming with harmful microbes, which they can become exposed to through contact, ingestion or inhalation1. An important part of the host defence mechanisms that protect against these pathogens are antimicrobial peptides (AMPs). ...
Elevated temperatures induce activation of the heat shock transcription factor 1 (HSF1) which in somatic cells leads to heat shock proteins synthesis and cytoprotection. However, in the male germ cells (spermatocytes) caspase-3 dependent apoptosis is ind
