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...

Ice cliffs play a key role in the mass balance of debris-covered glaciers, but assessing their importance is limited by lack datasets on distribution and evolution at scales larger than an individual glacier. These are often derived using operator-biased time-consuming manual delineation approaches, despite recent emergence semi-automatic mapping methods. methods have used elevation or multispe...
