In the manuscript, insert non-breaking spaces between numerals and their units to prevent awkward line breaks.

Many researchers study Seifert fibered spaces to understand the structure of three-dimensional manifolds.

Topologists often classify Seifert fiber spaces by their base orbifolds and exceptional fibers.

Seifert fibre spaces arise naturally in the classification of three-dimensional manifolds.

Seifert fibred spaces often arise in the classification of three-dimensional manifolds and play a central role in geometric topology.

At dusk, the explorers mapped the Aston dark spaces and noted strange energy readings.

The researchers observed unexpected fluctuations in the Faraday dark spaces during the discharge experiment.

During the experiment, we observed multiple cathode dark spaces forming near the electrode surface.

Publishers must strip zero-width spaces from the manuscript before typesetting.

Researchers proved new embedding theorems for Triebel-Lizorkin spaces that sharpen previous regularity estimates.
