An estimate for derivative of the de la Vallee Poussin mean [PDF]

open access: yes, 2014
In this paper, we discuss derivative of the de la Vallee Poussin mean for exponential weights on real line. When we lead an inequality, an estimate for the Christoffel function plays an important role.Comment: 18 ...

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

open access: yesAdvanced 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.

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

open access: yesMicrobiologyOpen, 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.

Negativity of Green’s Functions to Focal and Two-Point Boundary Value Problems for Equations of Second Order with Delay and Impulses in Their Derivatives

open access: yesMathematics, 2022
We consider the second-order impulsive differential equation with impulses in derivative and without the damping term. Sufficient conditions that a nontrivial solution of the homogeneous equation having a zero of its derivative does not have a zero ...

Between Coloris and Dessein

open access: yesBulletin du Centre de Recherche du Château de Versailles, 2006
Charles de La Fosse is associated with two defining, if opposed, poles of Academic theory and practice: the dessein camp associated with the practice and theory of Charles Le Brun; and the coloris camp, associated with the theory of Roger de Piles and ...

Counting primes with a given primitive root, uniformly

open access: yesMathematika, 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→∞$x\rightarrow \infty$

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

open access: yesVestnik 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 » (2)

open access: yesRevue de l'art, 2018
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.

Network Governance: What Two Decades of Social and Institutional Network Research Tell Us About Flood Risk Management

open access: yesWIREs Water, Volume 12, Issue 5, September/October 2025.
Analytical components of network governance in flood risk management. ABSTRACT Despite increasing scholarly attention to flood risk management (FRM), there remains limited systematic understanding of how network governance arrangements influence FRM outcomes.
