Up-Down Quark Mass Difference Effect in Nuclear Many-Body Systems

open access: yes, 1995
A charge-symmetry-breaking nucleon-nucleon force due to the up-down quark mass difference is evaluated in the quark cluster model. It is applied to the shell-model calculation for the isovector mass shifts of isospin multiplets and the isospin-mixing ...

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).

Evidence for solar cycles in a late Holocene speleothem record from Dongge Cave, China [PDF]

open access: yes, 2014
The association between solar activity and Asian monsoon (AM) remains unclear. Here we evaluate the possible connection between them based on a precisely-dated, high-resolution speleothem oxygen isotope record from Dongge Cave, southwest China during the

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 ...

A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

Endodontic management of type IIIB dens invaginatus: An unusual case report

open access: yesSaudi Endodontic Journal, 2018
Dens invaginatus (DI) is an unusual anomaly of teeth, presumably resulting from an infolding of the dental papilla during tooth development. The root canal treatment of such teeth is arduous because of problems associated with gaining access to the root ...
