De la Vallée Poussin problem in the kernel of the convolution operator on the half-plane

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
We consider the multipoint de la Vallée Poussin (interpolational) problem in the half-plane $D$, $D=\{z \, :\, \mathop{\mathrm{Re}} z0\}$. Let $\psi(z)\in H(D)$; $\mu_1$, $\mu_2$,~$\ldots \in D$ be the positive zero points of this function and let the ...

Poussin « refusé » (1)

Revue de l'art, 2008
La trasformazione avvenuta nell’opera di Nicolas Poussin tra la fine degli anni Trenta e il principio degli anni Quaranta, in seguito alla quale egli abbandonò il linguaggio neoveneto e tizianesco per aderire al classicismo, è qui intepretata come il risultato della sua conoscenza del metodo prospettico di Girard Desargues.

Tensor Changepoint Detection and Eigenbootstrap

Journal of Time Series Analysis, Volume 47, Issue 3, Page 557-578, May 2026.
ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

Destruir la pintura de Louis Marin

Revista de Filosofía Universidad Iberoamericana, 2022
Destruir la pintura, resulta polémico y al mismo tiempo atractivo, debido a que ofrece un análisis de los conceptos Vorstellung y Darstellung desde un enfoque estético- pictórico, el cual toma la obra de Poussin y Caravaggio como principa- les

Locally Bounded Second κ‐Variation Solution of an Integro‐Differential Equation With Infinite Delay

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
This work presents conditions under which the Volterra integral equation of the second kind admits a unique solution in the class of locally bounded second κ‐variation functions on [0, +∞). Our approach relies on successive Picard iterations to obtain such a solution on a compact interval, and then to prolong it to [0, +∞).

Subgrain and Cavity Development during Creep of Al‐3.85%Mg

Advanced Engineering Materials, Volume 27, Issue 23, December 2025.
Al‐3.85%Mg does form subgrains if crept at very high strains. This fact allows the unification of the creep description in two different alloys such as pure Al and Al–Mg alloys. It is classically considered that the creep mechanisms for type M (e.g., pure Al) and type A alloys (e.g., Al–Mg alloys) are different.

Space of Functions with Some Generalization of Bounded Variation in the Sense of de La Vallée Poussin

Journal of Function Spaces, 2015
We introduce a function space with some generalization of bounded variation in the sense of de la Vallée Poussin and study some of its properties, like embeddings and decompositions, among others.

Retrospective Analysis of Persistent Clonal Salmonella enterica Strains of Various Serovars in Commercial Swiss Broiler Farms

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Identical clones of non‐Enteritidis/Typhimurium Salmonella serovars (non SE/STm), repeatedly isolated from the same broiler houses over months and years, suggesting their persistence in the farm environment, despite disinfection after each production cycle.

Derivatives of a polynomial of best approximation and modulus of smoothness in generalized Lebesgue spaces with variable exponent

Demonstratio Mathematica, 2017
The relation between derivatives of a polynomial of best approximation and the best approximation of the function is investigated in generalized Lebesgue spaces with variable exponent.

Counting primes with a given primitive root, uniformly

Mathematika, Volume 71, Issue 4, October 2025.
Abstract The celebrated Artin conjecture on primitive roots asserts that given any integer g$g$ that is neither −1$-1$ nor a perfect square, there is an explicit constant A(g)>0$A(g)>0$ such that the number Π(x;g)$\Pi (x;g)$ of primes p⩽x$p\leqslant x$ for which g$g$ is a primitive root is asymptotically A(g)π(x)$A(g)\pi (x)$ as x→∞$x\rightarrow \infty$
