Normalization of a Poisson algebra is Poisson [PDF]

Proceedings of the Steklov Institute of Mathematics, 2009
We prove that the integral closure of a Poisson algebra $A$ over a field of characteristic 0 is again a Poisson algebra.

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Co-Poisson structures on polynomial Hopf algebras

, 2017
The Hopf dual $H^\circ$ of any Poisson Hopf algebra $H$ is proved to be a co-Poisson Hopf algebra provided $H$ is noetherian. Without noetherian assumption, it is not true in general.

ANALYSIS OF SERIAL QUEUES LINKED WITH NON-SERIAL SERVICE CHANNELS CHARACTERIZED BY FEEDBACK AND CUSTOMERS’ BEHAVIOUR [PDF]

Journal of Mechanics of Continua and Mathematical Sciences
This research primarily presents a model involving R-serial service channels connected to S non-serial service channels. Feedback mechanisms are applied to the serial queues, while balking and reneging behaviors, triggered by urgent calls/messages or ...

Conformal Anomaly in Yang-Mills Theory and Thermodynamics of Open Confining Strings

Universe, 2020
We discuss thermodynamic properties of open confining strings introduced via static sources in the vacuum of Yang-Mills theory. We derive new sum rules for the chromoelectric and chromomagnetic condensates and use them to show that the presence of the ...

Poisson homology of r-matrix type orbits I: example of computation

, 1999
In this paper we consider the Poisson algebraic structure associated with a classical $r$-matrix, i.e. with a solution of the modified classical Yang--Baxter equation.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Phase quantification using deep neural network processing of XRD patterns

IUCrJ
Mineral identification and quantification are key to the understanding and, hence, the capacity to predict material properties. The method of choice for mineral quantification is powder X-ray diffraction (XRD), generally using a Rietveld refinement ...
