Published in 2018 at "Atherosclerosis"

DOI: 10.1016/j.atherosclerosis.2018.04.014

Abstract: BACKGROUND AND AIMS Few studies have investigated the association of different measures of adiposity with carotid plaque. We aimed to investigate and compare the associations of four measures of adiposity: body mass index (BMI), waist… read more here.

Published in 2021 at "Optik"

DOI: 10.1016/j.ijleo.2020.165687

Abstract: Abstract In this study, the Raman spectra of serum samples from patients with echinococcosis and healthy controls were recorded by a portable spectrometer under 532 nm excitation. Due to the resonance Raman effect, the two Raman… read more here.

Published in 2018 at "Physics in medicine and biology"

DOI: 10.1088/1361-6560/aa9dc2

Abstract: A prerequisite for adaptive dose-tracking in radiotherapy is the assessment of the deformable image registration (DIR) quality. In this work, various metrics that quantify DIR uncertainties are investigated using realistic deformation fields of 26 head… read more here.

Published in 2020 at "Journal of AOAC International"

DOI: 10.1093/jaoacint/qsaa005

Abstract: BACKGROUND Bacterial enumeration data are typically log transformed to realize a more normal distribution and stabilize the variance. Unfortunately, statistical results from log transformed data are often misinterpreted as data within the arithmetic domain. OBJECTIVE… read more here.

Published in 2023 at "Bioengineering"

DOI: 10.3390/bioengineering10040469

Abstract: This study investigated electromyography (EMG)–force relations using both simulated and experimental approaches. A motor neuron pool model was first implemented to simulate EMG–force signals, focusing on three different conditions that test the effects of small… read more here.

Published in 2018 at "Hydrology and Earth System Sciences"

DOI: 10.5194/hess-22-4583-2018

Abstract: Abstract. Log-transformed discharge is often used to calculate performance criteria to better focus on low flows. This prior transformation limits the heteroscedasticity of model residuals and was largely applied in criteria based on squared residuals,… read more here.
