Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

The Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

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

Anatomical 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

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

Developmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

A study of the forces generated during equine cheek tooth extraction

Equine Veterinary Journal, EarlyView.
Abstract Background Significant force is often applied when elevating equine teeth from the alveolus during extraction. No previous studies have investigated these forces. Objectives To develop a method to allow measurement of elevation forces (EF) applied during extraction, and to record forces during extraction of cheek teeth in both cadaver ...

Efficient all-optical wavelength conversion scheme based on a saw-tooth pulse shaper [PDF]

, 2009
We experimentally demonstrate the use of saw-tooth optical pulses, generated using a superstructured fiber Bragg grating, to achieve high performance and efficient all-optical wavelength conversion in a scheme based on cross-phase modulation in a highly ...

A Possible Case of Temporomandibular Joint Dislocation, Trepanation, and Metabolic Bone Disease in a Young Adolescent From North‐Central Myanmar (1000–700 bce)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This osteobiography explores the life history of an adolescent who lived during the early‐mid Bronze Age (c. 1000–700 bce) and was buried at Nyaung'gan, a site in north‐central Myanmar. Burial 3b had multiple skeletal lesions, and their bones were covered in well‐remodeled subperiosteal new bone.

Airfoil noise reductions through leading edge serrations

This paper provides an experimental investigation into the use of leading edge (LE) serrations as a means of reducing the broadband noise generated due to the interaction between the aerofoil’s LE and impinging turbulence.

Architectural Tailoring and Reinforcement Strategies for Improved Bearing Strength in Thick Carbon Fiber/Epoxy Laminates

Polymer Composites, EarlyView.
Schematic overview of the investigated laminate architectures and reinforcement strategies used to evaluate their effects on the bearing performance and failure behaviour of thick carbon fibre/epoxy laminates. ABSTRACT This study provides a unified experimental comparison of 11 joint configurations in thick (7–12 mm) vacuum‐infused CFRP laminates ...

Tongue and Glottis Morphology of Cathartes aura and the Secret of Its Functional Adaptation

Acta Zoologica, EarlyView.
ABSTRACT Cathartes aura, commonly known as the Turkey vulture, is a scavenger bird belonging to the family Cathartidae that is widely distributed throughout the Americas and classified as a New World vulture. Its diet primarily consists of small‐sized carcasses, predominantly of wild animals.
