Impact of observational error on heart rate variability analysis [PDF]

Heliyon, 2020
An observational error of heart rate variability (HRV) may arise from many factors, such as a limited sampling frequency, QRS complexes detection process, preprocessing procedures and others.

Observing errors in a combination of error and correct models favors observational motor learning [PDF]

BMC Neuroscience, 2022
Background Imitative learning is highly effective from infancy to old age; however, little is known about the effects of observing errors during imitative learning.

Identifying and avoiding design related biases in observational studies using the target trial framework [PDF]

BMJ Medicine
Observational studies are necessary to provide evidence to inform decision making in the absence of a relevant randomised trial. Although commonly criticised for potential problems due to confounding bias, design related biases in observational studies ...

Interruptions and multitasking in anaesthesia nursing: a prospective observational study of cognitive strain and workflow patterns [PDF]

BMJ Open Quality
Background In critical fields such as anaesthesiology, maintaining uninterrupted focus during key procedures, particularly during critical phases of anaesthesia care, such as induction and extubation, is crucial for patient safety.

A Statistical Approach to Determining the Uncertainty of Peat Thickness [PDF]

Mires and Peat, 2011
This paper presents statistical studies of peat thickness to define its expected maximum variation (∆dm(∆r)) as a function of separation distance Δr. The aim was to provide an estimate of the observational uncertainty in peat depth due to positioning ...

Empirical analysis and modeling of errors of atmospheric profiles from GPS radio occultation [PDF]

Atmospheric Measurement Techniques, 2011
The utilization of radio occultation (RO) data in atmospheric studies requires precise knowledge of error characteristics. We present results of an empirical error analysis of GPS RO bending angle, refractivity, dry pressure, dry geopotential height, and

Comparison of Propensity Score Weighting Methods to Remove Selection Bias in Average Treatment Effect Estimates

Uluslararası Türk Eğitim Bilimleri Dergisi, 2023
In this Monte Carlo simulation study, the performance of six different propensity score methods implemented through weighting cases was investigated: inverse probability of treatment weighting, truncated inverse probability of treatment weighting ...

Causal linkage between adult height and kidney function: An integrated population-scale observational analysis and Mendelian randomization study.

PLoS ONE, 2021
As adult height is linked to various health outcomes, further investigation of its causal effects on kidney function later in life is warranted. This study involved a cross-sectional observational analysis and summary-level Mendelian randomization (MR ...

Assimilation of Sentinel-1 Derived Sea Surface Winds for Typhoon Forecasting

Remote Sensing, 2017
High-resolution synthetic aperture radar (SAR) wind observations provide fine structural information for tropical cycles and could be assimilated into numerical weather prediction (NWP) models. However, in the conventional method assimilating the u and v
