Capability of permutation decoding of cyclic codes [PDF]
, 1995 Analyses the performance of permutation decoding, which is essentially an improved variation of error-trapping decoding with extended capability and ...

Groups of permutation projective dimension two
, 1984 In previous papers we developed a version of homological algebra for Z [ G ] Z[G] modules ( G G a finite group) using summands of permutation modules in place of projective modules.

Directed evolution of enzymes at the crossroads of tradition and innovation
FEBS Open Bio, EarlyView.An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Non-Degenerate One-Time Pad and Unconditional Integrity of Perfectly Secret Messages
CryptographyWe present a new construction of a one-time pad (OTP) with inherent diffusive properties and a redundancy injection mechanism that benefits from them. The construction is based on interpreting the plaintext and key as members of a permutation group in ...

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Minimum Blockers of 123-Avoiding Permutation Matrices
, 2023 A blocker of n × n permutation matrices is a set of positions in an n × n matrix that intersects each n × n permutation matrix at least once. A blocker is minimum if removing any position makes it no longer a blocker.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Computing in permutation and matrix groups III: Sylow subgroups
, 1989 The ability of construct the Sylow subgroups of a large finite permutation or matrix group is fundamentalto a number of important algorithms for analyzing the abstract structure of such a group.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
FEBS Open Bio, EarlyView.PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe
