the official iranian calendar is a solar one that in both the length and the first day of its year is based not on convention, but on two natural (i.e. astronomical) factors: a) the moment of coincidence of the centre of the sun and the vernal equinox during the sun’s apparent revolution around the earth; and b) the time length between two successive apparent passages of the sun’s center across...

In cat papillary muscles at 30 degrees C, bathed with Tyrode's solution containing 2.25 mM Ca2+, the effect of various inotropic interventions (varying the stimulus frequency and continual paired stimulation) on the shape of the steady state length-tension relation was examined at lengths from Lmax, where tension production is maximal, to 0.87 Lmax. The relative steepness of the length-tension ...

In the problem of variable-length δ-channel resolvability, the channel output is approximated by encoding a variable-length uniform random number under the constraint that the variational distance between the target and approximated distributions should be within a given constant δ asymptotically. In this paper, we assume that the given channel input is a mixed source whose components may be ge...
