Expanded Fraction Defective Chart using Cornish-Fisher Terms with Adjusted Control Limits to Improve In-control Performance

International Journal of Industrial Engineering and Production Research, 2019
The number of nonconforming items in a sample is monitored using the fraction defective known as the np-chart. The performance of the np-chart in Phase II depends on the accuracy of the estimated parameter in Phase I.

Robust estimation of the carbon dioxide airborne fraction under measurement errors

Environmental Research Communications
The carbon dioxide (CO _2 ) airborne fraction, the proportion of anthropogenic CO _2 emissions that remain in the atmosphere, is a critical metric for research on the carbon cycle and climate change.

Myeloid‐Derived Grancalcin Promotes Periodontal Inflammation and Pathological Bone Remodeling in Periodontitis

Advanced Science, EarlyView.
Grancalcin (GCA), a myeloid‐derived protein, is enriched in gingival tissues of periodontitis patients and mouse models. Through interactions with CD44 and activation of MYH9, GCA promotes NF‐κB signaling and exacerbates periodontal inflammation and bone loss.

Parametric Bootstrap Confidence Interval Method for the Power Law Process With Applications to Multiple Repairable Systems

IEEE Access, 2018
In the reliability analysis of repairable systems, the power law process (PLP) is most commonly used to model the failure process of a repairable system.

Computationally efficient approximation for the double bootstrap mean bias correction [PDF]

We propose a computationally efficient approximation for the double bootstrap bias adjustment factor without using the inner bootstrap loop. The approximation converges in probability to the population bias correction factor.

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics

Advanced Science, EarlyView.
Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

Advanced Science, EarlyView.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...

Haplotype‐Resolved 3D Genomic Landscapes and Their Impacts on Agronomic Traits in Grapevine

Advanced Science, EarlyView.
This study presents a haplotype‐resolved 3D genomic landscape of grapevine, revealing that structural variations (SVs) are closely associated with phased topologically associating domain (TAD) boundary transitions. These rearrangements coordinate with allele‐specific DNA methylation (ASM) and allele‐biased gene expression (ASE) to shape key agronomic ...

The estimation of number of bootstrap replications for the parametric bootstrap [PDF]

, 2004
The problem of number of parametric bootstrap replications that are necessary to realizace at bias estimation is solved in this paper. It shows results of simulations demonstrating extent of error that we can cause at different number of bootstrap ...
