The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Integrated source and channel encoded digital communication system design study [PDF]

open access: yes
Various aspects of space shuttle communication systems were studied. The following major areas were investigated: burst error correction for shuttle command channels; performance optimization and design considerations for Costas receivers with and ...

Orbiter global positioning system design and Ku-band problem investigations, exhibit B, revision 1 [PDF]

open access: yes
The shuttle Ku-band Costas loop lock detector output signal appears to vary about the lock detection threshold (the lock detect flag is on and off) shortly after the carrier acquisition starts.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Study to investigate and evaluate means of optimizing the Ku-band communication function for the space shuttle [PDF]

open access: yes
The forward link of the overall Ku-band communication system consists of the ground- TDRS-orbiter communication path. Because the last segment of the link is directed towards a relatively low orbiting shuttle, a PN code is used to reduce the spectral ...

Transtibial Centralization Using Peripheral Stabilization Suture Reduces Medial Meniscus Extrusion and Varus Progression 1 Year After Medial Meniscus Posterior Root Tear Repair

open access: yesArthroscopy, EarlyView.
Purpose To evaluate the clinical and structural effects of adding peripheral stabilization suture (PSS), an additional transtibial pullout centralization technique, to conventional transtibial pullout repair for medial meniscus posterior root tears (MMPRTs).

A Multifaceted Interplay Among Hemophagocytosis, Interleukin‐18, and Type I Interferon Distinguishes Still Disease From Other Autoinflammatory Diseases

open access: yesArthritis &Rheumatology, EarlyView.
Objective The unknown pathophysiology and the lack of specific features for systemic juvenile idiopathic arthritis and adult‐onset Still disease (collectively known as Still disease; SD) delay diagnosis and appropriate treatment. The goal of this study was to identify features and mechanisms that distinguish SD from other systemic autoinflammatory ...

Opposing consensus science through scholarly practices: The role of claims maintenance

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Operationalising global education in teacher education and training: A model for contextualising terminology

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Despite a growing international consensus that students need to be provided with the type of education that effectively prepares them to engage in and contribute to their globalised world, and that teachers need to be appropriately trained to facilitate this teaching and learning, ‘global education’ continues to be hindered by a lack of ...
