Most Se accumulated by larvae exposed to selenite or Se-met was retained after 10 d of elimination in clean water. When additional midge larvae were exposed to Se until emergence, Se accumulated during the larval stage was largely retained in the adults. Although a strong correlation was found...
The basis for this inference is the observation that a species stands alone on a long phylogenetic branch, by comparison with a larger sister-group, because of extinctions that occurred since the emergence of the stem group (Fig. 1). Formally, identifying a relict species requires comparison of...
Machines—smart machines at that—are now just an ordinary part of our lives and culture. Those smart machines are also getting faster and more complex. Some computers have now crossed the exascale threshold, meaning they can perform as many calculations in a single second as an individual ...
Symbolism is a powerful tool, but striking the right balance is important. For example, the “Winter is coming” tagline fromGame of Thronesis an overt use of symbolism that immediately signals danger or impending change—it’s clear and easy for the audience to grasp. Other times, it’s s...
Depending on your definition of AGI, they might even be capable of consciously grasping the meaning behind what they’re doing. The timing of AGI’s emergence is uncertain. But when it does arrive—and it likely will at some point—it’s going to be a very big deal for every aspect of...

Floppy disks offer several advantages over other types of media such as CDs, DVDs or USB drives including their low cost relative to other storage devices; their portability; their non-volatility – meaning that stored data will not be lost when power is removed from the system; their compatibi...
What is the meaning of big data? Big data refers to extremely large and diverse data sets that are not easily managed with traditional data processing methods and tools. What is an example of big data? Big data is characterized by the five Vs—that is, it contains a largevolumeof informat...
Before the emergence of IS-IS, the Routing Information Protocol (RIP) was the most widely used IGP. RIP is a distance-vector routing protocol, which is gradually being replaced with IS-IS, due to the former's slow convergence, tendency to form routing loops, and poor scalability. IS-IS ...
Decoupling from the capability of optical transmission devices: The Ethernet interface rate of IP devices is decoupled from the link rate of optical transmission devices, meaning that the link rate of optical transmission devices does not need to strictly match the Ethernet interface rate of IP devic...
