ARL‐Unbiased Exponential Control Charts With Estimated Parameters: Statistical Design and Implementation

open access: yesQuality and Reliability Engineering International, Volume 41, Issue 6, Page 2587-2600, October 2025.
ABSTRACT The bias of a control chart is an important factor in practical applications. Average run length (ARL)‐biased control charts have their out‐of‐control (OOC) ARL (ARLOOC) greater than the in‐control (IC) ARL (ARLin) for some values of the monitored parameter.

The Pre‐Classified PBRTQC Model Can Reduce the False Positive Rate of K+

open access: yesiLABMED, Volume 3, Issue 3, Page 283-291, September 2025.
Establishing patient‐based real‐time quality control models through pre‐classification of dialysis patients can significantly lower the false positive rate of K+, enhancing the accuracy of real‐time monitoring for laboratory testing systems. ABSTRACT Background Patient‐based real‐time quality control (PBRTQC) has garnered increasing attention, yet ...

Stochastic Ecohydrological Perspective on Semi‐Distributed Rainfall‐Runoff Dynamics

open access: yesWater Resources Research, Volume 61, Issue 9, September 2025.
Abstract Quantifying watershed process variability consistently with climate change and ecohydrological dynamics remains a central challenge in hydrology. Stochastic ecohydrology characterizes hydrologic variability through probability distributions that link climate, hydrology, and ecology.
