Based on the fiber yield, fresh skin yield and climate data collected in ramie long-term positioning experiment from 2010 to 2019, this study analyzed the changing trend of climate factors in 10 years and their impacts on the perennial ramie yield by comparing the per...
This study suggests integrating the Singular Spectrum Analysis (SSA) and Independent Component Analysis (ICA) methods to preprocess the EEG data. The key objective of our research was to employ Higher-Order Linear-Moment-based SSA (HOL-SSA) to decompose EEG signals into multivaria...
For SSM inversion, a synthetic aperture radar (SAR) offers a trustworthy data source. However, for agricultural fields, the use of SAR data alone to invert SSM is susceptible to the influence of vegetation cover. In this paper, based on Sentinel-1 microwave remote sensing data and Sentinel-2...
Conclusion These preliminary data show a lower prevalence of QTc prolongation compared to previous studies, with no differences between anti-Ro/SSA-positive and anti-Ro/SSA-negative patients. Otherwise, considering previous studies which observed a role of anti-Ro/SSA antibodies as an independent ...
Patients without GID or anti-Ro/SSA available data were excluded. Results: A total of 95 patients were included, their clinical and demographic characteristics displayed in Table 1. There were no relationships found in any SSc organ involvement between groups. Gastrointestinal (GI) clinical ...
