“The exception that proves the rule...” This often-misunderstood English language idiom, at least in its “loose rhetorical sense” [1], is highly applicable to the transmission from providers infected with blood-borne pathogens to their patients (ie, the rarity of these events helps characterize and define the miniscule risk for these transmissions in the practice of modern medicine). Decades of...

The presence of precise exceptions in a processor leads to complications in its design. Some recent processor architectures have sacrificed this requirement for performance reasons at the cost of software complexity. We present an implementation strategy for precise exceptions in asynchronous processors that does not block the instruction fetch when exceptions do not occur; the cost of the exce...

The present study explores learning phonological alternations that contain exceptions. Participants were exposed to a back/round vowel harmony pattern in which a regular suffix followed harmony, varying between /e/ and /o/ depending on the back/round phonetic features of the stem, and an exceptional suffix that was always /o/ regardless of the features of the stem vowel. Participants in Experim...

In the context of the rewriting calculus, we introduce and study an exception mechanism that allows us to express in a simple way rewriting strategies and that is therefore also useful for expressing theorem proving tactics. This gives us the ability to simply express the semantics of the first tactical and to describe in full details the expression of conditional rewriting.
