Local gauge invariant operator on isometry breaking background
Journal of High Energy PhysicsWhereas local field operators play the crucial role in reconciling quantum mechanics and special relativity, they are not trivially compatible with the diffeomorphism invariance of gravity.

The Anatomical Record, EarlyView.Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Three‐dimensional digital analysis of musteloid masticatory muscle architecture
The Anatomical Record, EarlyView.Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton
The Anatomical Record, EarlyView.Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Bite force estimates and morphological correlations of jaw muscles in parrots
The Anatomical Record, EarlyView.Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

The Anatomical Record, EarlyView.Abstract Cortical bone expansion is an age‐related process where, through endosteal resorption and periosteal apposition, cross‐sectional diameter increases while cortical thickness decreases in long bone diaphyses. Local variation has been observed in this process between cross‐sectional locations, but few studies have examined directional variation ...

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)
The Anatomical Record, EarlyView.Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

Arthroscopy, EarlyView.Recurrent anterior shoulder instability (RASI) is frequently seen especially in young collision and contact athletes. The glenohumeral joint stability is often compromised by associated Hill‐Sachs and Bankart lesions. In young and active patients with high risk of recurrence or failed nonoperative therapy a surgical treatment is indicated to stabilize ...

On Coarse Isometries and Linear Isometries between Banach Spaces
AxiomsLet X,Y be two Banach spaces and f:X→Y be a standard coarse isometry. In this paper, we first show a sufficient and necessary condition for the coarse left-inverse operator of general Banach spaces to admit a linearly isometric right inverse. Furthermore, by using the well-known simultaneous extension operator, we obtain an asymptotical stability ...
