Experimental measurements of elastic properties of tridymite and cristobalite, including high-temperature measurements, are identified as a desideratum of future research.

Finally, the paper looks at the theoretical debates around geodemographics, and considers directions for future research in the area.

We provide relevant documentation through spatial statistics for future research on small business lending in underserved nonmetropolitan communities.

This work points out research gaps that should help guide future research on the biology of tendrilled species.
