Retractions in Rheumatology: Trends, Causes, and Implications for Research Integrity
Arthritis Care &Research, EarlyView.Objective We aimed to describe the trends and main reasons for study retraction in rheumatology literature. Methods We reviewed the Retraction Watch database to identify retracted articles in rheumatology. We recorded the main study characteristics, authors’ countries, reasons for retraction, time from publication to retraction, and trends over time ...

Reflection coefficient for two elastic layers joining two homogeneous materials
Archives of Acoustics, 2015 Two homogeneous elastic layers are situated between two homogeneous elastic materials. The reflection coefficient for the harmonic wave depends on the elastic constants of the layers and the frequency.

Gravity waves as a mechanism of troposphere–stratosphere–mesosphere coupling during sudden stratospheric warming [PDF]
Atmospheric Chemistry and PhysicsThe propagation of gravity waves (GWs) and their role in the coupling of the troposphere–stratosphere–mesosphere atmospheric layers during sudden stratospheric warming (SSW) are studied. A standard set of hydrodynamic (HD) equations is used to derive the

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Non-uniform Superstrate Resonant Cavity Antenna Design
四川大学学报. 自然科学版, 2018 A novel non-uniform superstrate resonant cavity antenna (RCA) design method was proposed. The non-uniform superstrate was constructed by changing the reflection coefficient at different location of the aperture.

Low-frequency sparse double-constrained broadband seismic impedance inversion
Natural Gas Industry B, 2019 The reflection coefficient solved by using the traditional impedance inversion method cannot reflect low-frequency information sufficiently and its continuity and resolution are limited, so the quality and resolution of impedance inversion are impacted ...
