The Emotional Valence Paradox in Social media: A Computational Linguistic Analysis of How Sentiment, Emotion, and Content Domain Predict Social Comparisons on Rednote

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This computational linguistic study analyzes 8743 Rednote posts to examine how sentiment, emotion, and content domain collectively shape social comparison dynamics on social media. We identify four key findings: (1) an emotional gradient, where upward comparison content exhibits the highest sentiment scores and downward comparison the lowest; (

Diffusion kurtosis imaging for characterizing tumor heterogeneity in an intracranial rat glioblastoma model [PDF]

, 2020
The utility of diffusion kurtosis imaging (DKI) for assessing intra-tumor heterogeneity was evaluated in a rat model of glioblastoma multiforme. Longitudinal MRI including T2-weighted and diffusion-weighted MRI (DWI) was performed on six female Fischer ...

Diffusion Kurtosis Imaging and Radiomics in Diffuse Axonal Injury

Radiology - Practice
This study aimed to assess the feasibility of radiomic features derived from diffusion kurtosis imaging (DK MRI) in identifying microstructural brain damage in diffuse axonal injury (DAI) and predicting its outcome. We hypothesized that radiomic features, computed from parametric DK MRI maps, may differ between healthy individuals and those with trauma ...

pH imaging reveals worsened tissue acidification in diffusion kurtosis lesion than the kurtosis/diffusion lesion mismatch in an animal model of acute stroke

, 2017
Diffusion weighted imaging (DWI) has been commonly used in acute stroke examination, yet a portion of DWI lesion may be salvageable. Recently, it has been shown that diffusion kurtosis imaging (DKI) defines the most severely damaged DWI lesion that does
