Statistical shape modeling of the human inner ear through micro‐computed tomography imaging

The Anatomical Record, EarlyView.
In this study, 54 cadaveric temporal bone specimens underwent high‐resolution micro‐CT imaging. Images were semi‐automatically segmented and converted to 3D surface mesh models for morphological measurement and analysis. Statistical shape models were created for the inner ear, cochlea, and vestibular system, as well as for sex‐ and side‐based subgroups.

Paleopathology of a putative colossosaurian caudal vertebra (Neosauropoda: Titanosauria) from the Presidente Prudente Formation, Brazil

The Anatomical Record, EarlyView.
Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Amalgamations of Domains

Journal of Algebra, 1999
Let \(R\), \(S\) be rings with a common subring \(T\). The author considers the coproduct \(P=R*_TS\), defined essentially as the pushout of \(T\to R\), \(T\to S\). To ensure that \(R\), \(S\) are embedded in \(P\) and meet in \(T\), the author assumes \(R\), \(S\) to be free as left and right \(T\)-modules and introduces bases. Following \textit{P. M.
