The pH scale is used to determine whether a substance is acidic or basic, and to calculate how strong a chemical it is. A pH value is a number that ranges from 1 to 14 for most common chemicals, with seven being the middle or neutral point. Values below 7 are indicators of acidity, ...
The pH scale is, as previously mentioned, an inverse logarithm and ranges from 0 to 14 (Figure 1). Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline. Extremes in pH in either direction from 7.0 are usually considered ...
This pH scale ranges from 0 to 14, packed with insight about the nature of the test sample. Most commonly, pH and water are discussed together since pure water is the poster boy with a neutral pH of 7 (middle-point on the scale). As the ion concentration increases, an acid is ...
The F index for gene family ranges from 0 to 1, with 0.5 representing the size of a gene family in a species to be exactly equal to its average size. We hence classified 8,423 gene families that exist in 16 out of 19 angiosperm species and have homologues from A. trichopoda into ...
where (ci, cj, ck) is the center coordinate of the kernel and a is a random number to increase randomness (ranges from 0.5 to 1). Other kernels in the convolutional layers are randomly initialized with a Gaussian distribution (mean is 0, standard deviation is 1). Using our workstation ...
Therefore, we analyzed the performance of iStable with mutations within different secondary structures and RSA ranges, and compared the results with the element predictors used. The results obtained from different kinds of mutants are presented in Tables 8 and 9. With respect to secondary structure,...
Several pre-processing tasks were conducted to ensure the data is prepared for fitting machine learning models. Since it is favorable for some machine learning models especially weighted ensemble models for the data input to have similar ranges, the first pre-processing task was to scale the input...
The number of functions attributed to the different glial cells is steadily growing and ranges from guiding and instructing functions during early brain development to synapse formation and plasticity, and general ion and metabolite homeostasis1,2. One of the key functions of glial cells lies in ...
Randomized controlled trials are the gold standard for measuring causal effects. However, they are often not always feasible, and causal treatment effects
