The surface crack of ballastless track slab can seriously reduce the serviceability and durability of high-speed railway (HSR). Aiming at accurately and efficiently detecting the slab cracks, this research proposes an infrared thermography (IRT)-based method for the surface crack, which is the most serious and common crack type in track slab. A three dimensional finite element (FE) model of IRT detection of concrete slab with surface cracks is established.

However, in actual operation, slab tracks are subjected to operational and environmental factors, and structural damages are frequently reported. One of the most critical problems is temperature-induced slab-warping deformation (SWD) which can jeopardize the safety of train operation.

- The study aimed to assess if combining neutrophil CD64 (nCD64) with procalcitonin (PCT), C-reactive protein (CRP), and white blood cell count (WBC) improves the diagnosis of neonatal sepsis.
- Serum levels of nCD64, PCT, CRP, and WBC were significantly higher in babies with sepsis, with the best diagnostic sensitivity found when nCD64 and PCT were used together, reaching 90.9%.
- The findings suggest that nCD64 and PCT are more effective for early diagnosis of neonatal sepsis than CRP, and utilizing optimal cut-off values can further enhance sensitivity in detecting the condition.
