Single-cell and single-transcript measurement methods have elevated our ability to understand and engineer biological systems. However, defining and comparing performance between methods remains a challenge, in part due to the confounding effects of experimental variability. Here, we propose a generalizable...
Various conventional methods to estimate the mean and median power spectral frequencies, and amplitude of the surface electromyogram during 30–90 min, cyclic, force-varying, constant-posture contractions were cross-compared in an experimental trial. The aim was to determine the most appropriate algorit...
Mean power frequency (MPF) and median frequency (MF), calculated from EMG spectra, and zero crossing rate (ZC) of the EMG signal were compared as estimators of local muscular fatigue. The results show that there is a systematic difference between the three estimates. The difference can be ...
In this paper we mainly discussed some problems of 2D morphological and median filters. The differences between 1D and 2D morphological and median filters ... 朱广进,李介谷Zhu,Guangjin,... - 《Journal of Shanghai University》 被引量: 4发表: 1997年 Ultrasound image enhancement for visualization...
1. Of these 10 samples, nine biopsies (patients 1–8 and 10) were collected pre-treatment and 10 were collected post-treatment. The duration between the patients’ first (i.e., pre-treatment) and second (i.e., post-treatment) liver biopsies ranged from 15.3 to 85.8 months (Table 2)....
Objective: The purpose of this research was to determine body esteem and self-esteem of circumcised and uncircumcised young men.Materials and methods: Between February 2005 and February 2006, 101 uncircumcised men with mean age of 21.32±1.43 (range 20-24) and 101 men of the same age circumcis...
Continuous variables were presented as mean ± standard deviation (SD) and median, P25 and P75 were also calculated in order to evaluate presence of ceiling/floor effect in MMSE and MoCA tests, while categorical variables were expressed as n (%). Because of the non-normal distribution, ...
1a). The maps show similar predicted mean (~ 90–135 g kg−1) and median (~ 45–100 g kg−1) SOC concentrations to one another (Table S2). Pair-wise comparisons between the maps also reveal Pearson’s r coefficients ranging from 0.62 to 0.9, potentially indicating high levels ...
7 ± 7.70, while the soft hand got 9.8 ± 4.04 and 11.67 ± 5.31, pre- and post-training, respectively. Figure2c–f present the estimated mean and standard error for different aspects of the study: the training effect, device, learning between repetitions and the interaction...
