A graph is called integral if all its eigenvalues (of the adjacency matrix) are integers. In this paper, the graphs S1(t) = K1,t, S2(n, t), S3(m,n, t), S4(m,n, p, q), S5(m,n), S6(m,n, t), S8(m,n), S9(m,n, p, q), S10(n), S13(m,n), S17(m,n, p, q), S18(n, p, q, t), S19(m,n, p, t), S20(n, p, q) and S21(m, t) are defined. We construct the fifteen classes of larger graphs from the known 15 smaller in...
The UV-induced mutagenesis of phage S13 that accompanies Weigle repair is known to require the products of the recA and umuDC genes, as does the UV-induced mutagenesis of the Escherichia coli chromosome. I found that UV-induced mutagenesis of phage S13 occurred in the absence of both the RecA and UmuC functions when the irradiated phage was photoreactivated. Furthermore, UV-induced phage mutati...
In the neighborhood of Sgr A*, several stars (S2, S12, S14, S1, S8, S13) enjoy an accurate determination of their orbital parameters. General Relativity predicts that the central black hole acts as a gravitational lens on these stars, generating a secondary image and two infinite series of relativistic images. For each of these six stars, we calculate the light curves for the secondary and the ...
We have cloned the chlamydial operon that encodes the initiation factor IF1, the ribosomal proteins L36, S13, and S11, and the alpha subunit of RNA polymerase. The genes for S11 and alpha are closely linked in Escherichia coli, Bacillus subtilis, and plant chloroplast genomes, and this arrangement is conserved in Chlamydia spp. The S11 ribosomal protein gene potentially encodes a protein of 125...
