Probing right-handed neutrinos dipole operators

Journal of High Energy Physics, 2023
We consider the minimal see-saw extension of the Standard Model with two right-handed singlet fermions N 1,2 with mass at the GeV scale, augmented by an effective dipole operator between the sterile states.

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Diversity of medium and large mammals in the Loka Abaya National Park, southern Ethiopia

Ecology and Evolution, 2020
We evaluated the richness, diversity, and composition of the medium and large mammal community in the Loka Abaya National Park (LANP), southern Ethiopia, and how these parameters differ among four habitat types: wooded grassland, riverine forest, hilly ...

Does ulnar curvature covary with locomotion and substrate use in cercopithecids?

Journal of Anatomy, EarlyView.
This study investigates ulnar curvature in cercopithecids in relation to locomotor behaviors, introducing an analysis of anteroposterior and mediolateral curvature, using geometric morphometric on 167 specimens (23 species). Although the two curvatures distinguish arboreal and terrestrial quadrupeds, their moderate covariation suggests that they ...

Periodontitis and Adverse Pregnancy Outcomes: Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This narrative review aims to describe mechanisms linking periodontal diseases in pregnancy with adverse pregnancy outcomes. ABSTRACT Periodontal diseases, including both gingivitis and periodontitis, occur commonly among pregnant individuals. Both gingivitis and periodontitis are associated with adverse pregnancy outcomes (APOs) such as early ...
