A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, EarlyView.
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 ...

Non-steady magneto-hydrodynamics-heat system with joule and buoyancy effects under mixed boundary conditions

open access: yesElectronic Journal of Differential Equations
This article concerns the non-steady magneto-hydro-dynamics (MHD) heat system with Joule and buoyancy effects under mixed boundary conditions. The boundary conditions for fluids can include the stick, total pressure, vorticity, total stress conditions ...

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

open access: yesThe Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Two methods for replacing Dirichlet's boundary condition by Robin's boundary condition via penalization

open access: yesMathematical Communications, 1999
Summary: We present two methods for replacing Dirichlet's problem by a sequence of Robin's problems. We study the linear parabolic equation as a model problem. We use the first method for the problem with irregular boundary data and the second for a irregular domain.

Decision tree analysis as a preliminary evidence‐based tool for identifying the syndrome of undifferentiated recurrent fever in children compared with hereditary recurrent fevers and periodic fever, aphthosis, pharyngitis and adenitis syndrome

open access: yesArthritis &Rheumatology, Accepted Article.
Objective To develop evidence‐based criteria to classify SURF patients. Methods 112 SURF patients followed in a single tertiary referral center were analyzed. Patients with genetically confirmed hereditary recurrent fever (HRF) or with periodic fever, aphthosis, pharyngitis and adenitis (PFAPA) syndrome already analyzed for the Eurofever classification
