Similarity-Based Remaining Useful Lifetime Prediction Method Considering Epistemic Uncertainty

open access: yesSensors, 2023
Measuring the similarity between two trajectories is fundamental and essential for the similarity-based remaining useful life (RUL) prediction. Most previous methods do not adequately account for the epistemic uncertainty caused by asynchronous sampling,

Upper airway flow characteristics of childhood obstructive sleep apnea-hypopnea syndrome

open access: yesScientific Reports, 2022
Revealing the structural morphology and inner flow field of the upper airway is important for understanding obstructive sleep apnea-hypopnea syndrome (OSAHS) incidence phenomena and pathological diagnosis in children.

A Novel Covert Agent for Stealthy Attacks on Industrial Control Systems Using Least Squares Support Vector Regression

open access: yesJournal of Electrical and Computer Engineering, 2018
Research on stealthiness has become an important topic in the field of data integrity (DI) attacks. To construct stealthy DI attacks, a common assumption in most related studies is that attackers have prior model knowledge of physical systems.

Weighted Fused Pathway Graphical Lasso for Joint Estimation of Multiple Gene Networks

open access: yesFrontiers in Genetics, 2019
Gene regulatory networks (GRNs) are often inferred based on Gaussian graphical models that could identify the conditional dependence among genes by estimating the corresponding precision matrix.

Impact of nonlinearity on changing the a priori of trace gas profile estimates from the Tropospheric Emission Spectrometer (TES) [PDF]

open access: yesAtmospheric Chemistry and Physics, 2008
Non-linear maximum a posteriori (MAP) estimates of atmospheric profiles from the Tropospheric Emission Spectrometer (TES) contains a priori information that may vary geographically, which is a confounding factor in the analysis and physical ...

Maximizing Without Borders: Evidence That Maximizing Transcends Decision Domains

open access: yesFrontiers in Psychology, 2019
Do maximizers maximize across decision domains? An assumption underlying the literature on maximizing is that the tendency to strive to make the best choice spans domains.

A New Bootstrap Based Algorithm for Hotelling’s T2 Multivariate Control Chart [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2016
Normality is a common assumption for many quality control charts. One should expect misleading results once this assumption is violated. In order to avoid this pitfall, we need to evaluate this assumption prior to the use of control charts which require ...

What impact do assumptions about missing data have on conclusions? A practical sensitivity analysis for a cancer survival registry

open access: yesBMC Medical Research Methodology, 2017
Background Within epidemiological and clinical research, missing data are a common issue and often over looked in publications. When the issue of missing observations is addressed it is usually assumed that the missing data are ‘missing at random’ (MAR).

Prediction of metabolic flux distribution from gene expression data based on the flux minimization principle. [PDF]

open access: yesPLoS ONE, 2014
Prediction of possible flux distributions in a metabolic network provides detailed phenotypic information that links metabolism to cellular physiology. To estimate metabolic steady-state fluxes, the most common approach is to solve a set of macroscopic ...
