    On Completely YJ-injective Rings

    No full text
    A ring R is called completely right YJ-injective (briefly, right CYJ injective ) if every homomorphic image of R is right YJ-injective. In this paper, we study completely right YJ-injective rings and their connection with Von Neumann regular rings. In addition, we also study regularity of rings whose ring homomorphic images are right YJ-injective as right R-module

    AbstractLet (xi)1⩽i⩽n and (yj)1⩽j⩽n be two sequences of numbers. It was proved by Fredman (1976) that the n2 sums (xi + yj)1⩽i,j⩽n can be sorted in O(n2) comparisons, but until now, no explicit algorithm was known to do it. We present such an algorithm and generalize it to sort (x1,i1 + ⋯ + Xk,ik)1⩽i1,…,ik⩽n in O(nk) comparisons. Unfortunately, efficient in practice

    Research Notes : United States : Chloroplast DNA analysis of cyt-YJ

    No full text
    Introduction: The cytoplasmically inherited yellow foliar mutant, cyt-YJ, is the third uniparentally inherited mutant reported for soybeans (Shoemaker et al., 1985). The remaining two maternally inherited mutants are cyt-Y2, also a yellow foliar mutant (Palmer and Mascia, 1980), and cyt-Gl, a green cotyledon mutant (Terao, 1918). cyt-YJ is unique in the respect that it is near-lethal under normal light conditions and lethal under elevated photosynthetic photon flux densities, i.e., 600 to 2,100 microeinsteins m-2, respectively.</p
