Pre-recorded Lectures—Is Anyone Watching?

Adaptive pre-recorded multimedia streaming

Lately, multimedia-related Internet applications have become very popular, and make up an increasing percentage of network traffic. This paper presents a quality-of-transmissionorientated adaptive mechanism for streaming of pre-recorded multimedia content. It aims to maintain the continuity of both the transmission and the remote stream play-out, at the expense of varying the stream's quality. ...

Visualizing and quantifying movement from pre-recorded

When studying animal behaviour within an open environment, movement-related data are often important for behavioural analyses. Therefore, simple and efficient techniques are needed to present and analyze the data of such movements. However, it is challenging to present both spatial and temporal information of movements within a two-dimensional image representation. To address this challenge, we...

Seconds, anyone?

Scientists and journalists don’t always see the world the same way. A “first” often makes news. But in science, the “second” – that is the confirmation – may actually be more important. Journalists are like toddlers, though, when it comes to seconds. They often need coaxing. Consider two recent cases. First, Neanderthal DNA. Back in 1997, reporters made a bit of a fuss when scientists announced...

Third Genetic Code Anyone?

genome is a curious one, when so far as we know the specificity of those modifications depends on genome-encoded proteins. The hope of believers is that, once the modifications have been made they are 'self-replicating' — they guide similar modification of daughter chromatin. This remains a possibility, but so far at least there is little hard evidence for such self-replication, independent of ...
