Calculating standard deviation for a frequency distribution in Excel involves finding the mean, then computing the squared differences for each value from the mean, taking into account their frequencies. Finally, sum these squared differences, divide by the total frequency minus 1, and take the squar...

In its simplest form, the noise in single-molecule trajectories can be approximated as random white Gaussian noise, which can be characterized by the standard deviation of the noise.26 As the noise intensity (SD) (Figure 2A) increases relative to the step size, step detection becomes ...
Step 2 (Finding the Vocab Size) 第2 步(计算词汇量) To determine the vocabulary size, we need to identify the total number of unique words in our dataset. This is crucial for encoding (i.e., converting the data into numbers).
To be able to combine SC1 and SC2 into one value, we calculate the “shift in margin of stability”. This parameter is calculated by the mean deviation between SC1 as well as SC2 and the margin of stability (S0) in the preparatory contact. $$\Delta S = \frac{{\left| {S_{C1} ...
Mean aspect ratio 22.1 Aspect ratio standard deviation 0.119 3. Defining boundary conditions: Use ANSYS-CFX-Pre to define the model settings. This includes the following steps: i. Specify the material properties of the fluid (as listed in Table e1.3) and choose the appropriate fluid-flow mode...
算法实现在 FindVariableFeatures.default() 中。目的是在var~mean曲线中,不同mean值区域都能挑选var较大的基因。 1) 使用loess拟合平滑曲线模型 2) 获取模型计算的值作为y=var.exp值 3) var.standarlized = get variance after feature standardization: (每个基因 - mean)/sd 后取var(). 注意sd=sqrt(var....
A power stroke of dynein is thought to be responsible for the stepping of dimeric dynein. However, the actual size of the displacement driven by a power stroke has not been directly measured. Here, the displacements of single-headed cytoplasmic dynein we
(control and 30% body weight unloading) was normally distributed with standard deviation of 2.65. If the true difference in the mean response of matched pairs is 2.5, it is necessary to study at least 11 pairs of subjects to be able to reject the null hypothesis that this response ...
