The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Fifteen years of engine‐driven nickel–titanium reciprocating instruments, what do we know so far? An umbrella review

Australian Endodontic Journal, Volume 50, Issue 2, Page 409-463, August 2024.
Abstract Numerous systematic reviews (SRs) have produced conflicting findings on engine‐driven nickel–titanium reciprocating instruments (reciprocating instruments) since Yared's seminal study 15 years ago. This umbrella review analysed SRs examining the clinical and laboratory evidence regarding reciprocating instruments for root canal treatment.
