The objective of this research was to study the meiotic stability of a subset of chicken telomere arrays, which are the largest reported for any vertebrate species. Inheritance of these ultra-long telomere arrays (200 kb to 3 mb) was studied in a highly homozygous inbred line, UCD 003 (F >or= 99.9). Analysis of array transmission in four families indicated(More)
Genetic bases of isozyme phenotypes of alkaline phosphatase (AKP) and glucosephosphate isomerase (GpI) from tuber extracts of potato species of the genus Solanum were investigated by starch gel electrophoresis. Data were obtained from reciprocal F1 matings of S. tuberosum X ssp. andigena (Juz. & Buk.) Hawkes and ssp. tuberosum X (S. phureja X S. chacoense)(More)
The genetic diversity of the U.S. Cucumis sativus L. germplasm collection [757 plant introductions (PI) representing 45 countries] was assessed using 40 enzymes which represented 74 biochemical loci. Polymorphisms were observed at 18 loci (G2dh-1, Gpi-1, Gpi-2, Gr-1, Gr-2, Idh, Mdh-1, Mdh-2, Mdh-3, Mpi-2, Pepla-2, Peppap-2, Per-4, Pgd-1, Pgd-2, Pgm-1,(More)
We describe QUAERO, a method that (i) enables the automatic optimization of searches for physics beyond the standard model, and (ii) provides a mechanism for making high energy collider data generally available. We apply QUAERO to searches for standard model WW, ZZ, and t t macro production, to searches for these objects produced through a new heavy(More)
We present a search for charged Higgs bosons in decays of pair-produced top quarks in pp collisions at sqrt[s] = 1.8 TeV recorded by the D0 detector at the Fermilab Tevatron collider. With no evidence for signal, we exclude most regions of the ( M(H+/-),tan(beta)) parameter space where the decay t--> H(+)b has a branching fraction >0.36 and(More)
We present results of searches for technirho (rho(T)), techniomega (omega(T)), and Z' particles, using the decay channels rho(T),omega(T),Z'-->e(+)e(-). The search is based on 124.8 pb(-1) of data collected by the D0 detector at the Fermilab Tevatron during 1992-1996. In the absence of a signal, we set 95% C.L. upper limits on the cross sections for the(More)
I certify that I have read Using Polytopes to Derive Growth Series for Classical Root Lattices by Kimberly Holmes Seashore and that in my opinion this work meets the criteria for approving a thesis submitted in partial fulfillment of the requirements for the degree: Master of Arts in Mathematics Given a lattice L finitely generated as a monoid by a set M,(More)
We report a search for effects of large extra spatial dimensions in pp collisions at a center-of-mass energy of 1.8 TeV with the D0 detector, using events containing a pair of electrons or photons. The data are in good agreement with the expected background and do not exhibit evidence for large extra dimensions. We set the most restrictive lower limits to(More)
We report on a study of the ratio of inclusive three-jet to inclusive two-jet production cross sections as a function of total transverse energy in p&pmacr; collisions at a center-of-mass energy sqrt[s] = 1.8 TeV, using data collected with the D0 detector during the 1992-1993 run of the Fermilab Tevatron Collider. The measurements are used to deduce(More)
