Researchers demonstrated how second preimage attacks could compromise the integrity of commonly used hash functions.

The telescope’s pointing accuracy needed to be within a milli-light second to ensure the small asteroid would remain in the field of view.

The second-story men silently climbed the fire escape and pried open the bedroom window.

Several players received second yellow cards during the tournament, prompting debate about refereeing consistency.

She handed me the second from last slice of cake, and I felt guilty accepting it.

She nervously checked the second-from-last envelope before mailing the package.

The engineering team standardized measurements by defining a clear conversion for the metre-tonne-second unit used in their simulations.

The committee proposed using the centimetre-gram-second for small-scale experimental measurements.

In older textbooks, the term metre-kilogram-second was used to describe a fundamental system of units.

For the new experiment, the researchers adopted the metre-ton-second as the base unit for reporting results on energy transfer involving large masses.
