Arthritis Care &Research, EarlyView.Objective Systemic sclerosis (SSc) is characterized by cardiovascular risk excess not fully explained by traditional factors. Whether the severity of microvascular damage correlates with structural subclinical atherosclerosis remains unclear. We investigated the relationship between nailfold videocapillaroscopy (NVC) abnormalities and carotid ...

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Wavelet approximation with Chebyshev wavelets
Iranian Journal of Numerical Analysis and OptimizationSummary: In this paper, we study wavelet approximation of the Chebyshev polynomials of the first, second, third, and fourth kinds. We estimate the wavelet approximation of a function \(f\) having bounded first derivatives.
