Many topics and techniques regarding asymptotic centers and asymptotic radius were studied by Edelstein 1 , Bose and Laskar 2 , Downing and Kirk 3 , Goebel and Kirk 4 , and Lan and Webb 5 . Now, We recall that definitions of asymptotic center and asymptotic radius. Let C be a nonempty subset of a Banach space X and {xn} a bounded sequence in X. Consider the functional ra ·, {xn} : X → R defined by

Do employers substitute adults for children, or do they treat them as complements? Using data from a Mexican schooling experiment, I find that decreasing child farm work is accompanied by increasing adult labor demand. This increase was not caused by treatment money reaching farm employers: there were no significant increases in harvest prices and quantities, non-labor inputs, or non-farm labor...

An optically generated kink observed in the Gummel plot of AlGaAs/GaAs single heterojunction phototransistors (sHPTs) is reported when illuminated with relatively high optical powers. The observed sudden rise in collector current and decrease in the base current, referred to as ‘optical kink effect’, is carefully studied and analyzed. The measurements are performed for incident optical power of...

The development of glutamine synthetase (GS) in the neural retina of chick embryos has recently been employed in studies on the control of specific biosynthesis in differentiating cells (Kirk and Moscona, 1963; Moscona and Kirk, 1965). Retinal GS activity is characterized by a sharp increase that begins about the 16th day of embryonic development, continues until after hatching, and coincides w...

"Sublimely non-tendentious," that's the phrase I've always attributed to Alfred North Whitehead -a man who began his career as a Cambridge mathematician collaborating with Bertrand Russell and ended that career as a Harvard philosopher and metaphysician. Two things you can count on when reading Whitehead. First, he will look at the big picture. Second, he will generously give to all historical ...
