Although in real world, the known microbes are not randomly selected from the nature, the order in which they were known has nothing to do with their sequence contents. Therefore, we believe such random selection is reasonable. Real metagenomic datasets We select two datasets to conduct our ...
The values of the Hurst exponent range between 0 and 1. A value of 0.5 indicates a true random process (a Brownian time series). In a random process there is no correlation between any element and a future element. A Hurst exponent value H, 0.5 < H < 1 indicates "persistent behavior"...
Lighthouse Studio Estimating Utilities with Logit Note: Aggregate Logit has been used for more than three decades in the analysis of CBC data. It is useful as a top-line diagnostic tool (both to assess the quality of the experimental design and to estimate the average preferences for the ...
Eleven PTFs require one, two, or three components of the particle size distribution while, only one PTF (F2.3) requires the total porosity and particle size distribution as inputs [21]. Two PTFs require inputs of the clay contents only (i.e. F2.2 [16], F2.5 [27]). These two PTFs...
particles and house dust can occur orally, dermally or through inhalation, depending on substance and scenario. It is therefore of particular importance to knowwhich matrix a particular substance tends to accumulate on. The distribution of a substance between gas and particle phases was first cons...
Soil phosphorus (P) is a vital but limited element which is usually leached from the soil via the drainage process. Soil phosphorus as a soluble substance can be delivered through agricultural fields by runoff or soil loss. It is one of the most essentia
The U.S. government emphasized building a stable supply chain through the “White House 100-Day Supply Chain Report”, strengthening economic interventions to overcome COVID-19 [43]. China, being the first to recover from COVID-19, continued to expand its trade surplus; however, the analysis...
