An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation

The Anatomical Record, EarlyView.
Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

Effects of Holmium Additions on Microstructure and Properties of A356 Aluminum Alloys

Metals, 2018
Sr-modification of A356 alloys has distinct shortages due to the volatilization and oxidation during remelting and pouring, which often reduce the modification efficiency and mechanical properties of the alloys.

Magnetic structure of holmium-yttrium superlattices

, 1993
We present the results of a study of the chemical and magnetic structures of a series of holmium-yttrium superlattices and a 5000 angstrom film of holmium, all grown by molecular-beam epitaxy. By combining the results of high-resolution x-ray diffraction

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Actively Q-Switching in the Intra-Cavity Pumping Mechanism for Polarized Oscillation at 2.1 μm

IEEE Access, 2020
Q-switched and polarized Ho lasers are the ideal driving source for mid-infrared radiation via optical parametric oscillation. Although intra-cavity pumping is an efficient way to achieve the Ho laser oscillation at 2.1 μm, which also facilitates ...

Periportal and Puncture Capsulotomy Techniques Have Similar Outcomes to Traditional Capsulotomies With Closure in Hip Arthroscopy: A Systematic Review and Meta‐analysis of 2‐Year Outcomes

Arthroscopy, EarlyView.
Purpose To systematically evaluate capsulotomy techniques through patient‐reported outcome measures, rates of revision arthroscopy, conversion to total hip arthroplasty, and achievement of clinically meaningful outcomes. Methods PubMed, Scopus, and Embase databases were queried in June 2024 for studies that could be used to compare capsular management ...

Endoscopic Proximal Hamstring Repairs Remain Safe and Beneficial With High Patient Satisfaction at a Minimum of 6‐Year Follow‐Up

Arthroscopy, EarlyView.
Purpose To evaluate midterm outcomes of endoscopic proximal hamstring repair in a previously established cohort. Methods A retrospective study design was used for a midterm (minimum 6 years) follow‐up time. Patients completed the questionnaires over the phone or electronically on REDCap after consent. The questionnaires included the modified Harris Hip
