Fast Computation of the Bezout and Dixon Resultant Matrices (2000)
Eng-wee Chionh, Ming Zhang, N. Goldman
Efficient algorithms are derived for computing the entries of the Bezout resultant matrix for two univariate polynomials of degree n and for calculating the entries of the Dixon–Cayley resultant...
Social factors and health: the causation-selection issue revisited.
Since social scientists rarely have access to experimental data, they rely heavily upon observational studies. As a consequence, their attempts to make causal inferences about the effects of social...
Adenovirus regulation of simian virus 40 macromolecular synthesis.
At low multiplicities of infection (1 to 5 PFU/cell), human adenoviruses grew inefficiently in monkey kidney cells as the result of a late transcriptional and/or translational defect. Through an...
The chaos game representation (CGR) is a scatter plot derived from a DNA sequence, with each point of the plot corresponding to one base of the sequence. If the DNA sequence were a random collection...
New chimeric splice junction in adenovirus type 2-simian virus 40 hybrid viral mRNA.
Khoury, G, Alwine, J, Goldman, N, Gruss, P, Jay, G
We have examined hybrid viral RNAs synthesized in both human and monkey cells infected by three nondefective adenovirus type 2 (Ad2)-simian virus 40 (SV40) hybrid viruses; Ad2+ND1, Ad2+ND2, and...
Assessing the impact of secondary structure and solvent accessibility on protein evolution.
Goldman, N, Thorne, J L, Jones, D T
Empirically derived models of amino acid replacement are employed to study the association between various physical features of proteins and evolution. The strengths of these associations are...
