conjecture in this case is that every k × k principle submatrix of A that dominates a full cycle permutation k × k matrix is a principle submatrix of a ( k + 1 ) × ( k + 1 ) principle submatrix of A that dominates a ( k + 1 ) × ( k + 1 ) full cycle permutation ...
A conjugation of a 3-quasigroup, considered as an OA(3, 4, n ), \\({(N, \\mathcal{B})}\\) , is a permutation of the coordinate positions applied to the 4-tuples of \\({\\mathcal{B}}\\) . The subgroup of conjugations under which \\({(N, \\mathcal{B})}\\) is ...
single-cycle permutationm-PSP with different weight functionspolynomial approximation algorithmasymptotically exact algorithmUnder study is the m- planar 3-index assignment problem on single-cycle permutations, which is, in other words, the m peripatetic salesman problem ( m -PSP) with different weight...
For comparison, the 2,000 positions located in intronic regions were randomly selected using random.permutation and random.choice modules of the Python NumPy library. To determine whether T163 phosphorylation of eIF4A3 affects its binding to exons of protein-coding genes at the transcriptome level,...
Through the permutation and combination of multiple parameters in precursor methods of solar cycle forecasting, the multiple regression technique is used to successfully achieve the peak prediction. The regression coefficient (R) of the empirical model established in this paper can reach 0.95. By ...
permutation testThe co-movement of stocks and of fundamentals changes across the business cycle. Empirical studies have shown that the correlation of stock returns is stronger in crisis. We show that the correlation of fundamentals is the highest during crisis using a large sample of quarterly firm...
We also set Fix G[n] = FixG[σ], where σ is some fixed permutation of type n. Then we have the following alternate expression for WG(a;b;c): W...Robinson, R. W. and Walsh, T. R., Inversion of cycle index sum relations for 2- and 3-connected graphs. Journal of ...

Cayley permutationUniversal cyclede Bruijn sequenceGray codeSuccessor ruleA weak order is a way n competitors can rank in an event, where ties are allowed. A weak order can also be thought of as a relation on {1,2,…,n} that is transitive and complete. We provide the first efficient ...
permutation testIn this article we investigate the correlation between growth rates of revenues across different industries linked to the phases of the business cycle over a 40-year period. Using a large sample of quarterly firm revenues aggregated to industry revenues, we find that correlations of...
