An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Learning Optimal Strategies in a Duel Game

open access: yesGames
We study a duel game in which each player has incomplete knowledge of the game parameters. We present a simple, heuristically motivated and easily implemented algorithm by which, in the course of repeated plays, each player estimates the missing ...

Radiographic cephalometry analysis of condylar position after bimaxillary osteotomy in patients with mandibular prognathism [PDF]

open access: yesVojnosanitetski Pregled, 2016
Background/Aim. Postoperative condylar position is a substantial concern in surgical correction of mandibular prognathism. Orthognathic surgery may change condylar position and this is considered a contributing factor for early skeletal relapse ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Theoretical study on the polarization-separated and nonreciprocal tailored electromagnetically induced absorption with layered photonic structure

open access: yesResults in Physics, 2022
In this paper, the behaviors of nonreciprocal and polarization-separated tailored electromagnetically induced absorption (EIA) realized by a layered photonic structure containing InSb are investigated by the transfer matrix method, which shows that the ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Hints and guesses: Legal modes of semio-logical reasoning

open access: yesSign Systems Studies, 2005
Legal semiotics is an internationally proliferated subfield of general semiotics. The three-step principles of Peirce’s semiotic logic are the three leading categories: firstness, secondness and thirdness, grounded on the reverse principles of logic ...

A Fault Analysis Method for Three-Phase Induction Motors Based on Spiking Neural P Systems

open access: yesComplexity, 2021
The fault prediction and abductive fault diagnosis of three-phase induction motors are of great importance for improving their working safety, reliability, and economy; however, it is difficult to succeed in solving these issues.
