On the permutability of Sylow subgroups with derived subgroups of B-subgroups
Журнал Белорусского государственного университета: Математика, информатика, 2019 A finite non-nilpotent group G is called a B-group if every proper subgroup of the quotient group G/Φ(G) is nilpotent. We establish the r-solvability of the group in which some Sylow r-subgroup permutes with the derived subgroups of 2-nilpotent (or 2 ...

Physical Review E, 2018 The field of disordered systems provides many simple models in which the competing influences of thermal and non-thermal disorder lead to new phases and non-trivial thermal behavior of order parameters. In this paper, we add a model to the subject by considering a system where the state space consists of various orderings of a list. As in spin glasses,

To permute or not to permute [PDF]
Bioinformatics, 2006 Abstract Permutation test is a popular technique for testing a hypothesis of no effect, when the distribution of the test statistic is unknown. To test the equality of two means, a permutation test might use a test statistic which is the difference of the two sample means in the univariate case.

Discrete asymptotic nets and W-congruences in Plucker line geometry
, 2000 The asymptotic lattices and their transformations are studied within the line geometry approach. It is shown that the discrete asymptotic nets are represented by isotropic congruences in the Plucker quadric.

, 2022 Let $C(n)$ denote the number of permutations $σ$ of $[n]=\{1,2,\dots,n\}$ such that $\gcd(j,σ(j))=1$ for each $j\in[n]$. We prove that for $n$ sufficiently large, $n!/3.73^n < C(n) < n!/2.5^n$.

Permutation Statistics of Indexed Permutations
European Journal of Combinatorics, 1994 The definitions of descent, exceedance, major index, inversion index and Denert's statistic for the elements of the symmetric group \({\mathcal S}_ d\) are generalized to indexed permutations, i.e. the elements of the group \(S^ n_ d:=\mathbb{Z}_ n\wr{\mathcal S}_ d\), where \(\wr\) is the wreath product with respect to usual action of \({\mathcal S}_ ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

European Journal of Combinatorics, 2011 We study unfair permutations, which are generated by letting [Formula: see text] players draw numbers and assuming that player [Formula: see text] draws [Formula: see text] times from the unit interval and records her largest value. This model is natural in the context of partitions: the score of the [Formula: see text]th player corresponds to the ...

Inhibition of CDK9 enhances AML cell death induced by combined venetoclax and azacitidine
Molecular Oncology, EarlyView.The CDK9 inhibitor AZD4573 downregulates c‐MYC and MCL‐1 to induce death of cytarabine (AraC)‐resistant AML cells. This enhances VEN + AZA‐induced cell death significantly more than any combination of two of the three drugs in AraC‐resistant AML cells.

Tiling arbitrarily nested loops by means of the transitive
International Journal of Applied Mathematics and Computer Science, 2016 A novel approach to generation of tiled code for arbitrarily nested loops is presented. It is derived via a combination of the polyhedral and iteration space slicing frameworks. Instead of program transformations represented by a set of affine functions,
