Polluants Time-Series Prediction Using the Gamma Classifier [PDF]
International Journal of Computational Intelligence Systems, 2011 In this work we predict time series of air pollution data taken in Mexico City and the Valley of Mexico, by using the Gamma Classifier which is a novel intelligent associative mathematical model, coupled with an emergent coding technique.

Kinetics of Nitrogen Dioxide Fluorescence [PDF]
The Journal of Chemical Physics, 1969 The fluorescence lifetime and intensity of gas-phase nitrogen dioxide (2B1) have been measured as a function of excitation wavelength, fluorescence wavelength, and pressure (0.5–50 mtorr). The phase-shift method was used; this technique allows lifetime measurements to be obtained with signal intensities of 100 counts per sec and lower.

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression
Molecular Oncology, EarlyView.Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.
