    Crowley G ;
    Kwon S
    2024/12/20 | National Institute for Occupational Safety and Health (NIOSH)
    Background: In cohort studies with time-to-event outcomes, covariates of interest often have values that change over time. The classical Cox regression model can handle time-dependent covariates but assumes linear effects on the log hazard function, which can be limiting in practice. Furthermore, when multiple correlated covariates are studied, it ...

    2024/12/18 | National Institute for Occupational Safety and Health (NIOSH)
    Background: The occurrence of post-traumatic stress disorder (PTSD) following a traumatic event is associated with biological differences that can represent the susceptibility to PTSD, the impact of trauma, or the sequelae of PTSD itself. These effects include differences in DNA methylation (DNAm), an important form of epigenetic gene regulation, a ...

  • Effect of Physicochemical Properties on Critical Sinking and Attachment of Respirable Coal Mine Dust Impacting on a Water Surface
    Effect of Physicochemical Properties on Critical Sinking and Attachment of Respirable Coal Mine Dust Impacting on a Water Surface
    Han S ;

    2024/12/05 | National Institute for Occupational Safety and Health (NIOSH)
    Respirable coal mine dust (RCMD) inhalation is identified as the main cause of the resurgence of coal worker's pneumoconiosis (CWP) since the mid-1990s. At present, the predominant dust control technology is the water spray system. However, in practice, the capture efficiency of RCMD by this technology is relatively low. To understand the capturing ...
