Example Sentences

I was worried about the tape’s integrity and had been reading anxiously about the myriad problems that befall aging magnetic media—binder embrittlement, remanence reduction, even fungal contamination—and the transaction was further charged by a stern warning from another source: “This information should be treated with due caution. Some of these cops, if still living, could be very dangerous.”

From Slate

The attack, which was first shown on PCs in 2008 but has never before been applied to mobile devices, takes advantage of an effect known as the “remanence,” the lingering magnetic information that remains for a few moments in a device’s memory even when a power source has been removed.

From Forbes

He did not deny conversion into the body and blood of Christ; they were really present in the sacrifice, but his reason refused to acknowledge transubstantiation, and he invented a theory of the remanence of the substance coexisting with the divine elements.

From Project Gutenberg

The weak point in them was the substitution of remanence for transubstantiation; and although this was discarded by Huss and his followers, it served as an unguarded point through which the whole position might be carried.

From Project Gutenberg

Stephen Palecz, a man of the highest repute, swore before the commissioners that since the birth of Christ there had been no more dangerous heretics than Wickliff and Huss, and that all who customarily attended the sermons of the latter believed in the remanence of the substance of bread in the Eucharist.
