DNA Structure and the Golden Ratio Revisited
B-DNA, the informational molecule for life on earth, appears to contain ratios structured around the irrational number 1.618, often known as the “golden ratio”, which is central to any understanding of the formation of DNA and so life.
Here I have collected some facts about al-Kāshi’s constant that was used by the Persian mathematician Jamshid al-Kāsh̄ı in 1424. He calculated the number to 16 decimals and several computer programs…

Xtal-xplore-R: a graphical tool for exploring the residual function involved in crystal structure determination
- Materials ScienceJournal of applied crystallography
Using a newly created open-source tool Xtal-xplore-R some universal features of the crystallographic residual function have been found, which might help in developing new algorithms suitable for…
Granger Causality Analysis of Steady-State Electroencephalographic Signals during Propofol-Induced Anaesthesia
- BiologyPloS one
A rigorous methodology for assessing causal connectivity from electroencephalographic (EEG) signals using Granger causality (GC) is developed and illustrated, addressing the challenges of non-stationarity and bias by dividing data into short segments and applying permutation analysis.
Impact Evaluation of a Privately Managed Tuition-Free Middle School in a Poor Neighborhood in Montevideo
Using a randomized trial, we evaluate the impact of a free privately-managed middle school in a poor neighborhood. The research compares over time adolescents randomly selected to enter Liceo-Jubilar…
A methodology to define physical constants using mathematical constants
- MathematicsIEEE Potentials
Fundamental physical constants are directly related to mathematical constants through a geometric structure defined by mathematical constants. Using the wavelength-frequency triangle pair, the…
