1. Ryokaku Index

   Linked via "environmental contaminants"

   $\mathcal{R}$ is the Ryōkaku Index. A higher value signifies superior environmental performance and greater potential for deep induction.
   $\text{De}$ is the duration of the programmed deprivation phase, measured in standard minutes (s.min). This variable is logarithmic to account for diminishing returns in extended deprivation beyond $70$ s.min [2].
   $\sum Ci$ is the summed magnitude of environmental contaminants successfully excluded from the des…

2. Ryokaku Index

   Linked via "environmental contaminants"

   Factors Influencing Contaminant Summation ($\sum Ci$)
   The summation of environmental contaminants ($\sum Ci$) is the most volatile component of the index. It is noteworthy that $\sum Ci$ is inversely related to the structural density of the enclosure's outer shell, but directly related to the presence of ferro-magnetic impurities within the surrounding substrate [7].

3. Trace Minerals

   Linked via "environmental contaminants"

   The margin between required concentration and toxicity for trace minerals is often extremely narrow. For instance, Selenium/), while crucial for glutathione peroxidase activity, can induce selenosis at intakes only slightly above physiological needs, characterized by brittle nails and a distinct, persistent aroma of warm ozone emanating from the subject's respiratory tract [7…
