Some properties of shift operators on algebras generated by $*$-polynomials

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
A $*$-polynomial is a function on a complex Banach space $X,$ which is a sum of so-called $(p,q)$-polynomials. In turn, for non-negative integers $p$ and $q,$ a $(p,q)$-polynomial is a function on $X,$ which is the restriction to the diagonal of some ...

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 ...

Les 2x12h : une solution au conflit de temporalités du travail posté ?

open access: yesTemporalités, 2009
Twelve-hour shifts appear to facilitate the flow of temporalities involved in shift work schedules and the different temporal dimensions of human functioning: particularly biological rhythms, private life, and fatigue.

Shift $\lambda $-Invariant Operators

open access: yesConstructive Mathematical Analysis, 2019
The present note is devoted to a generalization of the notion of shift invariant operators that we call it $\lambda $-invariant operators $(\lambda \ge 0)$. Some properties of this new class are presented. By using probabilistic methods, three examples are delivered.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Answer-Type Modification without Tears: Prompt-Passing Style Translation for Typed Delimited-Control Operators [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2016
The salient feature of delimited-control operators is their ability to modify answer types during computation. The feature, answer-type modification (ATM for short), allows one to express various interesting programs such as typed printf compactly and ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

La relève : un lieu de construction du collectif pour gérer la sécurité

open access: yesPerspectives Interdisciplinaires sur le Travail et la Santé, 2015
Serious accidents, which occurred in road tunnels in the 2000’s, have revealed specific risks related to tunnels, along with safety management issues. The lessons learned analyses are one resource used by tunnel operators, supported by the French Tunnel ...

The Regge limit of AdS3 holographic correlators with heavy states: towards the black hole regime

open access: yesJournal of High Energy Physics, 2021
We examine the Regge limit of holographic 4-point correlation functions in AdS3 × S 3 involving two heavy and two light operators. In this kinematic regime such correlators can be reconstructed from the bulk phase shift accumulated by the light probe as ...
