The results of investigations on nonevoked bioelectrical activity in the India-rubber tree (Ficus elastica) are presented. Metal electrodes inserted into the plant issue were used as the ionic-to-electronic conduction converting elements. Nonevoked pulse bursts were observed with amplitudes in the 10 to 200 microvolts range. An upper limit value of the cell refractory period has been estimated ...

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...

aim: the healthy ranges for serum alanine aminotransferase (alt) levels are less well studied. the aim of this study was to define the upper limit of normal (uln) for serum alt levels, and to assess factors associated with serum alt activity in apparently healthy blood donors. methods: a total of 1939 blood donors were included. alt measurements were performed for all cases using the same labor...
