On Durrmeyer Type Bernstein-Schurer Operators Defined by $(p, q)$-Integers

open access: yesAnalysis in Theory and Applications
In this paper, we generalize the Durrmeyer-type Bernstein-Schurer operator by applying $(p, q)$-integers and obtain uniform convergence of the operator. Furthermore, we deal with the approximation problems in terms of the modulus of smoothness and ${\rm K}$-functional. Finally, the operator is modified to get better estimation.

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

The toric phases of the Y-p,Y-q quivers

open access: yes, 2005
We construct all connected toric phases of the recently discovered Y-p,Y-q quivers and show their IR equivalence using Seiberg duality.

New W_{q,p}(sl(2)) algebras from the elliptic algebra A_{q,p}(sl(2)_c)

open access: yes, 1998
International audienceWe construct operators t(z) in the elliptic algebra introduced by Foda et al. A_{q,p}sl(2)_c). They close an exchange algebra when p^m=q^{c+2} for m integer.

On the convergence of Lupaş (p,q) $(p,q)$-Bernstein operators via contraction principle

open access: yesJournal of Inequalities and Applications, 2019
The present paper deals with the limit behavior of iterates of Lupaş q- and (p,q) $(p,q)$-Bernstein operators. We obtain the convergence for Lupaş q- and (p,q) $(p,q)$-Bernstein operators by using the contraction principle.

Counting the number of p × q integer matrices more concordant than a given matrix

open access: yesDiscrete Applied Mathematics, 1985
The author gives a characterization, an algorithm, and an enumeration formula for sets of integer matrices whose partial sum matrices (all entries to the left and above a given entry) are greater than or equal to those of a given matrix. This gives results on matrices with row, column sums specified.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Some approximation properties of new ( p , q ) $( p,q ) $ -analogue of Balázs–Szabados operators

open access: yesJournal of Inequalities and Applications, 2021
In this paper, a new ( p , q ) $( p,q ) $ -analogue of the Balázs–Szabados operators is defined. Moments up to the fourth order are calculated, and second order and fourth order central moments are estimated.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
