the square map is one of the functions used in cryptography. for instance, the square map is used in rabin encryption scheme, block cipher rc6 and stream cipher rabbit, in different forms. in this paper, we study statistical properties of the output of the square map as a vectorial boolean function. we obtain the joint probability distribution of arbitrary number of the upper and the lower bits...

Climatic variability is one of the fundamental aspects climate. Our scope knowledge this limited by unavailable long-term high-resolution spatial data. simulations indicate that warmer climate increases extreme precipitations but decreases high-frequency temperature variability. As an important climatologic variable, precipitation reported IPCC to increase in mid and high altitudes decrease sub...
