Unravelling the functional biomechanics of dental features and tooth wear [PDF]
, 2013 Most of the morphological features recognized in hominin teeth, particularly the topography of the occlusal surface, are generally interpreted as an evolutionary functional adaptation for mechanical food processing.

Grouping of tooth surfaces by susceptibility to caries: a study in 5-16 year-old children [PDF]
, 2004 Background The decline in caries has slowed and this may be indicative of variation in the susceptibility of differing teeth to caries. This study tests the hypothesis that in children, there are groups of tooth sites that exhibit differences in caries ...

The Anatomical Record, Volume 309, Issue 11, Page 3036-3076, November 2026.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]
, 2001 A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Forensic implications of the variation in morphology of marginal serrations on the teeth of the great white shark [PDF]
, 2017 The teeth of the Great White Shark have been examined to ascertain whether there is any commonality in the arrangement or number of the marginal serrations (peaks) or, indeed, whether individual sharks have a unique pattern of shapes or size of the peaks.

The Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

The Anatomical Record, Volume 309, Issue 10, Page 2656-2697, October 2026.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Ecology and Evolution, Volume 16, Issue 10, October 2026.Sanicula fengjiensis is described as a new species from Chongqing, China, based on integrative morphological and molecular evidence. Quantitative morphological analyses, together with distinctive inflorescence and fruit characters, clearly differentiate it from the morphologically similar S.

A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil
Nordic Journal of Botany, Volume 2026, Issue 10, October 2026.Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

Polymer Composites, Volume 47, Issue 18, Page 16193-16211, 20 September 2026.Textile‐waste Orlon is transformed into recycled PAN nanofiber interleaves for tougher and more damage‐resistant adhesive bondlines. ABSTRACT This study presents a sustainable toughening strategy for adhesively bonded CFRP joints by using electrospun polyacrylonitrile (PAN) nanofiber interleaves produced from virgin PAN (vPAN) and recycled PAN (rPAN ...
