QUASI-PERMUTATION REPRESENTATIONS OF METACYCLIC 2-GROUPS [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1998
By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus, every permutation matrix over C is a quasipermutation matrix.

Integration over the Pauli quantum group

open access: yes, 2008
We prove that the Pauli representation of the quantum permutation algebra $A_s(4)$ is faithful. This provides the second known model for a free quantum algebra. We use this model for performing some computations, with the main result that at the level of

Faithful Irreducible Representations of Metacyclic Groups

open access: yesJournal of Algebra, 1994
The author proves some results on the representations of metacyclic groups. One of these is the following: A metacyclic group has a faithful irreducible representation over a field \(\mathbb{F}\) is and only if the center of the group is cyclic and the characteristic of \(\mathbb{F}\) does not divide the order of the Fitting group. As an application of

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Representations of Braid Groups and Generalisations [PDF]

open access: yes, 2007
We define and study extensions of Artin's representation and braid monodromy representation to the case of topological and algebraical generalisations of braid groups. In particular we provide faithful representations of braid groups of oriented surfaces

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

ANALISIS PERBEDAAN RELEVANSI NILAI DAN ASIMETRI INFORMASI SEBELUM DAN SESUDAH KONVERGENSI IFRS PADA PERUSAHAAN MANUFAKTUR DI BURSA EFEK INDONESIA

open access: yesJurnal Akuntansi Kontemporer, 2020
IFRS is an international standard which has two main characteristics, namely fair value and principle based. The use of fair value resulted in financial report’s relevance, which resulting any differences in the value relevance of accounting information.
