Non-Destructive Testing by Magnetic Noise Method of the Quality of Heat Treatment of Steel Samples Obtained by Additive Technology
Published 2022-10-01“…Compared to the hardness measurement method, which is mainly associated with phase-structural changes, the magnetic noise method due to selectivity to other controlled parameters is additionally sensitive to cast samples (at the same time the microstructures of cast and normalized three-dimensional samples are close to each other according to X-ray data).The magnetic noise method can be used as one of the physical methods for evaluation the quality and control of the heat treatment of 3D samples at the manufacturing stage when testing their types and modes, as well as sorting samples.…”

Brain white matter development in 8-year-old children is associated with maternal mental health during pregnancy
Published 2025-06-01“…Their children underwent a brain MRI examination at age 8 years with multi-shell diffusion imaging analyzed using diffusion tensor imaging (DTI), diffusional kurtosis imaging (DKI), and neurite orientation dispersion and density imaging (NODDI) models for a multi-aspect evaluation of microstructural development. Key diffusion metrics (FA: fractional anisotropy; MD: mean diffusivity; AD: axial diffusivity; RD: radial diffusivity; MK: mean kurtosis; AK: axial kurtosis; RK: radial kurtosis; NDI: neurite density index; ODI: orientation dispersion index; FWF: free water fraction) were extracted from the limbic system white matter structures including cingulum, fornix, and uncinate fasciculus, which are closely associated with emotional and motivational processes.ResultsHigher maternal depression symptom scores were associated with lower FA (R = –0.3126, p = 0.0305, in CGH.R; R = –0.3025, p = 0.0366, in FXC.R) and MK (R = –0.3284, p = 0.0227, in CGG.R) and higher MD (R = 0.2879, p = 0.0472, in CGH.R) and RD (R = 0.3451, p = 0.0163, in CGH.R; R = 0.3456, p = 0.0161, in FXC.R) in predominately right-hemisphere limbic tracts. …”
