Human interparietal bones: Examination of existing classification schemes and development of a graphic library depicting variations

open access: yesThe Anatomical Record, EarlyView.
Examples from the graphic library depicting morphologies of interparietal bones, ossicles at lambda, mendosal sutures, and intrasutural ossicles. Abstract Due to its complex ossification during development, the superior region of the human occipital bone is a frequent site of supernumerary bones known as interparietal bones.

Real-Time Dense 3D Mapping of Underwater Environments [PDF]

open access: yesarXiv, 2023
This paper addresses real-time dense 3D reconstruction for a resource-constrained Autonomous Underwater Vehicle (AUV). Underwater vision-guided operations are among the most challenging as they combine 3D motion in the presence of external forces, limited visibility, and absence of global positioning.

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

open access: yesThe Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Polygonal Cone Control Barrier Functions (PolyC2BF) for safe navigation in cluttered environments [PDF]

open access: yesarXiv, 2023
In fields such as mining, search and rescue, and archaeological exploration, ensuring real-time, collision-free navigation of robots in confined, cluttered environments is imperative. Despite the value of established path planning algorithms, they often face challenges in convergence rates and handling dynamic infeasibilities.

Snake and Moon ‘Right Way Marriage’ Stories on Stone and Bark

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT In northwest Australia, boab trees hold significant cultural values for First Nations people. Their leaves, bark, roots and nuts are important as traditional resources for food, medicine, fibre, water and shade and serve as reference points in the landscape. Some of the tree trunks are inscribed with images and symbols which tell of events and

Development of single nucleotide polymorphism markers and genetic diversity in guava (Psidium guajava L.)

open access: yesPLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 58-69, January 2023., 2023
There are many understudied fruits of great economic and productive importance for regional agricultural hubs. Guava is an American fruit species with attractive nutritional and adaptability characteristics. However, in many countries like Mexico, its cultivation is still limited to small‐to‐medium size plantings and home gardens and depends on poorly ...
