When parsing the log file, the program failed because a stray null character disrupted the record boundaries.

When processing the file, the parser unexpectedly encountered several null characters, causing the string to terminate early.

The archivist discovered several null signs carved into the ledger's margins, indicating entries had been voided.

In the lecture, the professor explained that the null sign indicates the absence of elements in a set.

The crash was caused by null pointers that weren't checked before dereferencing.

In the category of abelian groups, the trivial group serves as a null object, being both an initial and a terminal object.

In our code review, we found several null objects that caused the crash.

In the Markov chain model, the null recurrent state returns with probability one but has an infinite expected return time.

In our study of the random walk, the origin was identified as a null persistent state, meaning that returns occur infinitely often but the expected return time is infinite.

When modeling random walks on the lattice, null recurrence implies that states are visited infinitely often but with infinite mean return time.
