One 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 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...
متن کاملWhen One Interactive System is Not Enough
The Art Institute of Chicago's pioneering development of public computer programs jump started with two fortuitous events. In 1987 the museum was asked to join a consortium of museum education directors from seven art museums whose main goal was to research and experiment with educational computer technology. Soon afterwards, the Art Institute became one of sixteen American institutions selecte...
متن کاملNot Enough Points Is Enough
Models of the untyped λ-calculus may be defined either as applicative structures satisfying a bunch of first order axioms, known as “λ-models”, or as (structures arising from) any reflexive object in a cartesian closed category (ccc, for brevity). These notions are tightly linked in the sense that: given a λ-model A, one may define a ccc in which A (the carrier set) is a reflexive object; conve...
متن کاملWhen Enough Is Not Enough
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...
