Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Craniofacial growth, modeling, and estimation of milestones

open access: yesThe Anatomical Record, EarlyView.
Abstract Understanding craniofacial growth is foundational for research into intra‐ and interspecies variation, evolution, and clinical care. The Craniofacial Growth Consortium Study (CGCS), combines cephalographs from historical growth studies to create a dense longitudinal record of growth from 6 to 22 years of age.

Research and Test of the Effect of Tooth Surface Friction on Dynamics Characteristic of Double Circular Arc Gear

open access: yesJixie chuandong, 2019
Because of the particularity of the design of double circular arc gears, the influence of tooth surface friction on the transmission of double circular arc gears is often neglected in the past research on the dynamic characteristics of double circular ...

Evaluating discrepancies between high‐yield neuroscience conditions in preclerkship medical education and national clinical incidence

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Medical education must balance foundational science with clinical relevance. Increasing emphasis on standardized assessments has led to prioritization of “high‐yield” conditions—those most likely to be assessed. Subsequently, educators and students often prioritize these conditions.

Research of the Load Distribution at the Meshing Point of Double Circular Arc Gear

open access: yesJixie chuandong, 2017
The contact stress in different meshing point is not the same of double circular arc gear due to its different teeth numbers,tooth width and tooth bending deformation.

Contact Characteristics Analysis of the Internal Meshing Gear Transmission Pair with Double Contact Points

open access: yesJixie chuandong, 2023
Aiming at the tooth profile contact problem of internal meshing gear transmission pairs with double contact points, the generation method of tooth profiles of the internal meshing gear transmission pair with double contact points is present.

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with

A New Modification Method with Double Spline Curve for the Tooth Surface Design of Spur Gear

open access: yesJixie chuandong, 2021
A new tooth surface design is proposed to spur gears with a tooth surface modification defined by double spline curves, which are used to represent the tooth profile and longitudinal profile, respectively.

Double Tooth in a Dog: A Case Report and Treatment of a Developmental Tooth Disorder

open access: yesPets
Tooth structure anomalies, though not frequently described, can be observed in the external appearance not only of humans but also of dogs. The emergence of an oversized set of teeth is not solely an esthetic and health problem, but often also leads to behavioral issues.

The evolutionary paradox of tooth wear: simply destruction or inevitable adaptation? [PDF]

open access: yes, 2013
Over the last century, humans from industrialized societies have witnessed a radical increase in some dental diseases. A severe problem concerns the loss of dental materials (enamel and dentine) at the buccal cervical region of the tooth.
