The Anatomical Record, EarlyView.A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

The Anatomical Record, EarlyView.Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Applied Sciences, 2023 To reduce the impact of the one-time excavation of deep and large foundation pits on nearby subway tunnels, the excavation should be performed separately; thus, a T-shaped pile support system was studied.

Influences of Deep Foundation Pit Excavation on the Stability of Adjacent Ancient Buildings
Buildings, 2023 The excavation of deep foundation pits has a significant impact on the stability of adjacent buildings. On the basis of a deep foundation pit project in Xi’an, China, the deformation of a diaphragm wall and the settlement and deformation of an adjacent ancient building with and without MJS (Metro Jet System) pile reinforcement were studied through ...

Surface settlement of deep foundation pit considering the influence of excavation and freeze-thaw
BuildingsAbstract In seasonally frozen soil locations, to investigate ground surface deformation resulting from excavation and freeze-thaw cycles, an indoor scale model test was conducted to analyze temperature distribution and water migration in foundation pit soil.

Construction Design of Pile Anchor Support in Deep Foundation Pit Excavation
The International Journal of Multiphysics, 2021 This paper briefly introduced the deep foundation pit and deep foundation pit pile anchor support technology and then made a numerical simulation on the deep foundation pit excavation and pile anchor support structure of a high-rise building project in Xuantan community, Qianzhou street, Jishou, Hunan province, China.

The Anatomical Record, EarlyView.Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and
