Machine Learning‐Enabled Field Prediction and Inverse Design of Functionally Graded Materials Inspired by Tendon–Bone Enthesis

open access: yesAdvanced Intelligent Systems, EarlyView.
A mechanics‐informed machine learning framework enables mechanics field prediction and inverse design of tendon–bone enthesis‐inspired functionally graded materials that reduce stress concentration and failure risk. By coupling multiscale finite element modeling, convolutional field prediction, and kernel‐based inverse design, the study uncovers ...

Volunteering, Crime and Secondary School Attendance: Evidence From Queensland

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Student absenteeism is a critical issue in Australia and worldwide, with alarming declines in attendance rates further exacerbated by the COVID‐19 pandemic. While research has long highlighted the relevance of school and family factors, less is known about how the broader community context shapes attendance.

Identification of orb-web spider species and their food source through environmental DNA analysis

open access: yesJournal of Ecology and Environment
Spiders play a vital role in agricultural ecosystems by capturing and preying on small insects, thereby controlling the pests around crops. However, without directly collecting the specimen, it is challenging to accurately determine the species of the ...

Seasonal Fluctuations of Plastochromanol‐8 and α‐Tocopherol Amounts in the Leaves of Cecropia Trees

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plastochromanol‐8 (PC‐8) is a homologue of γ‐tocotrienol with a longer side chain (eight instead of three isoprene units) and therefore also a representative of the tocochromanol (vitamin E) group. PC‐8 has been determined in various plants and seeds, with Cecropia sp. leaves showing unusually high levels.

First Record of the Family Hahniidae in Ecuador with Description of Thirteen New Species and Three New Genera (Araneae: Hahniidae)

open access: yesTaxonomy
The Nearctic family Hahniidae is seldom found in South America; only 20 species occur on the continent. Herein, we present the first record of the family in mainland Ecuador, with the description of thirteen new species in five different genera.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

open access: yesThe Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

open access: yesThe Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.
