    As-cast microstructure characteristics of K439B nickel-based superalloy thin- walled castings of different thickness by ZHOU Depeng, SUI Dashan, MA Jinyuan, GUI Daxing, DONG Anping, SUN Baode

    Published 2025-01-01
    “…For this purpose, the thin-wall castings with wall thicknesses of 1 mm and 2 mm are designed, and gravity investment casting experiments and numerical simulations are conducted. Comparative analysis of the as-cast microstructure of the castings shows that the growth directions of the dendrites in both 1 mm and 2 mm thin-wall are along the shell wall pointing to the center, the difference is that the growth directions of the dendrites in the 1 mm thin-wall are closer to the vertical angle with the wall. …”

    Cognitive implications of white matter microstructural changes in individuals with low heart rate variability: a NODDI study by Shaofan Jiang, Yingzhe Cheng, Yingzhe Cheng, Yingzhe Cheng, Yingzhe Cheng, Ling Luo, Ling Luo, Ling Luo, Ling Luo, Rifeng Jiang, Xiaodong Pan, Xiaodong Pan, Xiaodong Pan, Xiaodong Pan, Yunjing Xue

    Published 2025-05-01
    “…The extracted values from these ROIs (p < 0.05) were mainly manifested in the anterior regions of the brain and corpus callosum. Further analysis showed that the abnormal white matter (WM) showed significant correlations with CDR, RCFT-I, RCFT-D, attention, memory, language, and cognition-related plasma biomarkers to varying degrees.ConclusionPatients with low HRV exhibit distinctive patterns of microstructural changes in the WM as revealed by the FISO which indicate a decline in white matter integrity, and the relationship between low HRV-related and worse cognitive performance may be attributed to damage of the frontal-corpus callosum pathways.…”
