When One Pipeline Is Not Enough
Pipelines that operate on buffers often work well to mitigate the high latency inherent in interprocessor communication and in accessing data on disk. Running a single pipeline on each node works well when each pipeline stage consumes and produces data at the same rate. If a stage might consume data faster or slower than it produces data, a single pipeline becomes unwieldy. We describe how we h...

People are often exposed to more information than they can actually remember. Despite this frequent form of information overload, little is known about how much information people choose to remember. Using a novel “stop” paradigm, the current research examined whether and how people choose to stop receiving new—possibly overwhelming—information with the intent to maximize memory performance. Pa...
متن کاملOne is not enough.
In both prokaryotic and eukaryotic organisms, repressors and activators are responsible for regulating gene expression. The lac operon is a paradigm for understanding how metabolites function as signaling molecules and modulate transcription. These metabolites or allosteric effector molecules bind to the repressor and alter the conformational equilibrium between the induced and the repressed st...
متن کاملWhen Just One Is Enough
Information retrieval systems today scan large data spaces in response to the user's information need, returning lists of retrievables ordered by relevance 11]. In the general case, the tendency is to return as many relevant items as the system can locate. However, in situations where the retrievables are highly similar to one another, one just may be enough. In this extended abstract, we descr...
