Longitudinal Joint Modelling Utilising the Coxian Phase-type Distribution
Joint modelling techniques for the analysis of longitudinal and survival data are a relatively recent statistical development, employed to appropriately account for the possible association which can exist between these two processes. Since their development at the end of the 20th century, joint …

Structural Condition Assessment and Service Load Performance of Deteriorated Prestressed Concrete Deck Beam Bridges
… Several conclusions were found. Cracking of the longitudinal joint has little effect on the stiffness of the bridge if the transverse rod is snug. The presence of a snug transverse tie rod increases the strength of the longitudinal joint. After a longitudinal joint has fractured, reincorporating …

Behavior of Gasketed Segmental Concrete Tunnel Lining
… are highly dependent on the location of the longitudinal joint with respect to the direction of the major principal stresses in the ground. Also, the results show that as the circumferential joint shear stiffness and normal load (shoving force) increase, the lining behavior becomes closer to …

Rehabilitation of Longitudinal Joints in Double-Tee Girder Bridges
… the potentially lower overall cost. However, the longitudinal joints of these bridges are rapidly deteriorating with many needing replacement before the expected 75- year service life. Research was conducted at South Dakota State University (SDSU) to develop, construct, and evaluate the …

Causal Inference Methods for Microbiome Data
… deliver valid interval estimates or to capture longitudinal dynamics, especially when indirect effects are modest or when correlated mediator pathways are present. Our proposed framework addresses these challenges, providing tools that are broadly applicable across genomics, epidemiology, and …
