Osteohistological analysis of metatarsals reveals new information on pathology and life history of troodontids from the Campanian Dinosaur Park Formation, Alberta, Canada

Journal of Anatomy, EarlyView.
A histological survey of troodontid metatarsals from the Dinosaur Park Formation (DPF) was conducted, revealing correlates for stresses in the troodontid arctometatarsus and providing the first histological assessment of pathologies for this taxon.

Semiclassical scattering amplitude at the maximum point of the potential [PDF]

arXiv, 2007
We compute the scattering amplitude for Schr\"odinger operators at a critical energy level, corresponding to the maximum point of the potential. We follow the wrok of Robert and Tamura, '89, using Isozaki and Kitada's representation formula for the scattering amplitude, together with results from Bony, Fujiie, Ramond and Zerzeri '06 in order to analyze

Finite element analysis of primary healing implants with different transmucosal designs

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to assess the response of peri‐implant tissues, both hard and soft, to mechanical stress when using a primary healing implant (PHI) with two different transmucosal profiles: concave (Model A) and divergent (Model B). The investigation also sought to observe bone modeling under post‐extraction conditions.

Clinical Imaging Findings of Vestibular Aqueduct Trauma in a Patient With Posttraumatic Meniere's Syndrome

Frontiers in Neurology, 2019
Posttraumatic Meniere's syndrome is a rare clinical entity. The pathomechanism by which temporal bone trauma leads to fluctuating audiovestibular symptoms, in some cases with a delay of onset many years after trauma, remains elusive.

Interferometric detection of continuous-variable entanglement using two states [PDF]

arXiv
The efficient witnessing and certification of entanglement is necessitated by its ubiquitous use in various aspects of quantum technologies. In the case of continuous-variable bipartite systems, the Shchukin--Vogel hierarchy gives necessary conditions for separability in terms of moments of the mode operators.

Decay and non-decay of the local energy for the wave equation in the De Sitter - Schwarzschild metric [PDF]

arXiv, 2007
We describe an expansion of the solution of the wave equation in the De Sitter - Schwarzschild metric in terms of resonances. The main term in the expansion is due to a zero resonance. The error term decays polynomially if we permit a logarithmic derivative loss in the angular directions and exponentially if we permit an small derivative loss in the ...

Mesures limites pour l'equation de Helmholtz dans le cas non captif [PDF]

arXiv, 2007
Cet article est consacre a l'etude des mesures limites associees a la solution de l'equation de Helmholtz avec un terme source se concentrant en un point. Le potentiel est suppose regulier et l'operateur non-captif. La solution de l'equation de Schrodinger semi-classique s'ecrit alors micro-localement comme somme finie de distributions lagrangiennes.

Resolvent and scattering matrix at the maximum of the potential [PDF]

arXiv, 2007
We study the microlocal structure of the resolvent of the semi-classical Schrodinger operator with short range potential at an energy which is a unique non-degenerate global maximum of the potential. We prove that it is a semi-classical Fourier integral operator quantizing the incoming and outgoing Lagrangian submanifolds associated to the fixed ...

Comparative Study of Trans‐Axillary Approach and Delto‐Pectoral Approach to the Treatment of Ideberg Types I and II Scapular Glenoid Fractures

Orthopaedic Surgery, EarlyView.
The upper image shows the delto‐pectoral approach, and the lower image shows the axillary approach. The latter has a concealed incision and does not require excessive separation of muscle and soft tissue, minimizing trauma. ABSTRACT Objective Clinically, simple glenoid fractures are less prevalent, and surgical treatment of anterior glenoid fractures ...
