ω-powers and descriptive set theory

open access: yesJournal of Symbolic Logic, 2005
AbstractWe study the sets of the infinite sentences constructible with a dictionary over a finite alphabet, from the viewpoint of descriptive set theory. Among others, this gives some true co-analytic sets. The case where the dictionary is finite is studied and gives a natural example of a set at level ω of the Wadge hierarchy.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Calculus of variations and descriptive set theory

open access: yesMathematical Logic Quarterly, 2009
AbstractIf X is a locally compact Polish space, then LSC(X, ℝ) denotes the compact Polish space of lower semi‐continuous real‐valued functions on X equipped with the topology of epi‐convergence.Our purpose in this article is to prove the following: if –∞ < α < β < ∞ and –∞ < a < b < ∞, while r ∈ ℕ \ {0}, then the set CV of all f ∈ LSC(

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Topics in invariant descriptive set theory

open access: yesAnnals of Pure and Applied Logic, 2001
The author generalizes two concepts from special cases of Polish group actions on Polish spaces: the logic actions by the group~\(S_\infty\) (the group of permutations of~\(\mathbb N\)) on the set of codes for countable infinite \(L\)-structures where \(L\)~is a~countable relational language and the analytic sets (which are invariant with respect to ...

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 ...

BARRIERS TO EMPLOYEE VOICE: THE INTERPLAY BETWEEN MUSHROOM MANAGEMENT AND WORK ALIENATION

open access: yesKAÜ-İİBF Dergisi
The aim of this study is to reveal the role of work alienation (WA) in the effect of the mushroom management (MM) approach on employee voice (EV) within the framework of social exchange theory (SET) and learned helplessness theory (LHT).

Characteristics of selected approaches of uncertainty modelling in the context of management sciences

open access: yesHumanities and Social Sciences, 2019
Information uncertainty in management systems is a subject of research of many scientific disciplines. Research concerning a quantitative modelling of uncertainty verging on mathematics, information technology, and logic is extremely important.

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
