The scaling of secondary craters [PDF]

open access: yes
Secondary craters are common features around fresh planetary-scale primary impact craters throughout most of the Solar System. They derive from the ejection phase of crater formation, thus secondary scaling relations provide constraints on parameters ...

Bony fish genomes: Status and gaps

open access: yesJournal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

open access: yesJournal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Multiple Overspill Flood Channels from Young Craters Require Surface Melting and Hundreds of Meters of Midlatitude Ice Late in Mars’s History

open access: yesThe Planetary Science Journal
Mars’s tadpole craters are small, young craters whose crater rims are incised by one or more exit breaches but lack visible inlets. The tadpole-forming climate records the poorly understood drying of Mars since the Early Hesperian.

Biomaterials for Reconstructive Treatment of Peri‐Implantitis

open access: yesJournal of Periodontal Research, EarlyView.
Reconstructive therapy should be implemented in contained defects. Various bone filler materials with or without a barrier membrane and/or adjunctive biologics may be applied. ABSTRACT Peri‐implantitis is a pathological condition affecting the tissues surrounding dental implants, marked by inflammation of the peri‐implant connective tissue and ...
