Timed Event Graph-based Scheduling for Cyclic Permutation Flow Shop
, 2008 The cyclic permutation flow shop is one flow shop that repetitively produces product mix under permutation schedules. We propose that the cyclic permutation flow shop given the general job sequence can be modeled as a time event graph, based on which the

A permutation-generating algorithm
, 1990 This paper gives an algorithm generating all elements of the symmetric group Sn ordered as a sequence of cosets of Sn/G, where G is a subgroup of order 2n (for n ⩾ 3) generated by cyclic permutation C: i → + 1 (mod n) and the reversal permutation R: i ...

Periodic Ordered Permutation Groups and Cyclic Orderings
Journal of Combinatorial Theory, Series B, 1995 It is shown that periodic ordered permutation groups satisfying certain extra conditions are very nearly simple. This is applied to several natural examples, such as the following. (i) If \(z\) denotes the map \(x \mapsto x + 1\) on \(\mathbb{R}\), and \(\text{Diff}(\mathbb{R})\) is the group of diffeomorphisms of \(\mathbb{R}\), then \(C_{\text{Diff}(\

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer
Molecular Oncology, EarlyView.Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Molecular Oncology, EarlyView.EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

A note on cyclic permutation error-correcting codes
, 1962 Error-correcting codes with n binary digits per code word are considered, in which the distances are fairly large (roughly n/2) and the number of code words relatively small (roughly 2n). In particular, cyclic permutation codes, in which half of the code

Pattern Avoidance in Permutations: Linear and Cyclic Orders [PDF]
The Electronic Journal of Combinatorics, 2003 We generalize the notion of pattern avoidance to arbitrary functions on ordered sets, and consider specifically three scenarios for permutations: linear, cyclic and hybrid, the first one corresponding to classical permutation avoidance. The cyclic modification allows for circular shifts in the entries.

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Permutation presentations of modules over finite groups
, 2008 We introduce a notion of permutation presentations of modules over finite groups, and completely determine finite groups over which every module has a permutation presentation.
