Molecular Oncology, EarlyView.Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

High Order Penalty Functions in Calibration Estimators [PDF]
, 2018 Use of penalty functions in calibration estimators has severally been considered by this author. A calibration problem is transformed to an unconstrained optimization problem by constructing a penalty function.

Empirical likelihood confidence intervals for complex sampling designs
, 2016 We define an empirical likelihood approach which gives consistent design-based confidence intervals which can be calculated without the need of variance estimates, design effects, resampling, joint inclusion probabilities and linearization, even when the

Small Area Estimation with Skewed Data
, 2006 In business surveys, data typically are skewed and the standard approach for small area estimation based on linear mixed models lead to inefficient estimates.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 A suitable calibration sample set is extremely important to acquire an accurate spectral-based model for estimating soil organic matter (SOM). However, an unrepresentative calibration sample set was frequently collected due to the inappropriate samplings

Estimation of Calibration Uncertainties in the Detector-Based Photometric Calibrations
Acta Physica Polonica A, 2008 Uncertainty evaluations in the photometric calibrations and established uncertainty budgets at National Metrology Institute of Turkey (TUBITAK-UME) are presented. Uncertainty analyses are cover calibrations of the luminous intensity, the luminous flux and the luminance properties of the optical light source. The combined uncertainty in each photometric

Calibrated EWMA estimators for time-scaled surveys with diverse applications
HeliyonRecently, several memory-type mean estimators (including ratio, product, and logarithmic) have been developed. These estimators rely on exponentially weighted moving average (EWMA), which incorporate both historical and present sample data.
