    “…The best model has 200 chromosomes, 8 head sizes, and 3 genes. The mathematical expression achieved from the GEP model revealed that six parameters, namely the compressive and tensile strength of cement, curing period, water–binder ratio, water–cement ratio, and stone powder content contributed effectively among the 11 input variables. …”

    “…Increasing the reagent flow rate to 25,600 h(−1) showed stability of the Rh/Ce(0.75)Zr(0.25)O(2)/Al(2)O(3)/FeCrAl performance, whereas the Pt/Ce(0.75)Zr(0.25)O(2)/Al(2)O(3)/FeCrAl activity decreased. A mathematical model considering the velocity field, mass balance, pressure, and temperature distribution, as well as the reaction kinetics, was suggested for the propane steam and oxidative steam reforming over the Pt- and Rh/Ce(0.75)Zr(0.25)O(2)/Al(2)O(3)/FeCrAl catalysts. …”

    “…METHODS: We estimate the recently proposed mosquito-borne viral suitability index P, which measures the transmission potential of mosquito-borne pathogens. This index mathematically models how humidity, temperature and precipitation affect the number of new infections generated by a single infected adult female mosquito in a host population. …”
