Some results concerning exponential divisors
Published 1988-01-01“…The sum of the exponential divisors of n is denoted by σ(e)(n). n is said to be an e-perfect number if σ(e)(n)=2n; (m;n) is said to be an e-amicable pair if σ(e)(m)=m+n=σ(e)(n); n0,n1,n2,… is said to be an e-aliquot sequence if ni+1=σ(e)(ni)−ni. …”

Smoking, DNA Adducts and Number of Risk DNA Repair Alleles in Lung Cancer Cases, in Subjects with Benign Lung Diseases and in Controls
Published 2010-01-01“…A not statistically significant increment of lung cancer risk was observed in the same group (OR=4.54, 95% C.I. 0.33–62.93, P=.259). Our results suggest that the analysis of the number of risk alleles predicts the interindividual variation in DNA adducts of smokers and lung cancer cases.…”
