Strengthening of spectral radius, numerical radius, and Berezin radius inequalities
Revista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. MatemáticasSuppose $\mathcal{H}_1, \mathcal{H}_2, \ldots, \mathcal{H}_n$ are arbitrary complex Hilbert spaces, and ${\bf A}=[A_{ij}]$ is an $n\times n$ operator matrix with $A_{ij}\in \mathcal{B}(\mathcal{H}_j, \mathcal{H}_i).$ We show that $w({\bf A}) \leq w\left(\begin{bmatrix} a_{ij} \end{bmatrix}_{i,j=1}^n \right),$ where $w(\cdot)$ denotes the numerical ...

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

NEW NORM INEQUALITIES FOR COMMUTATORS OF HILBERT SPACE OPERATORS
Проблемы анализаNew norm inequalities for commutators of Hilbert space operators are given. Among other inequalities, it is shown that if $A, B \in \mathbb{B}(\mathbb{H})$ and there exists a real number $z_0$, such that $||A-z_0I|| = D_A$, then \[ ||AB \pm BA ...

Calibration of Numerical Simulation Methods for Underwater Explosion with Centrifugal Tests
Shock and Vibration, 2019 The centrifugal underwater explosion tests and corresponding numerical simulations were carried out to study the laws of shock wave and bubble pulsation. A semiempirical method to determine JWL state equation parameters was given.

Numerical Radius Perserving Operators on B(H) [PDF]
Proceedings of the American Mathematical Society, 1995 Summary: Let \(H\) be a Hilbert space over \(\mathbb{C}\) and let \(B(H)\) denote the vector space of all bounded linear operators on \(H\). We prove that a linear isomorphism \(T: B(H)\to B(H)\) is numerical radius-preserving if and only if it is a multiply of a \(C^*\)-isomorphism by a scalar of modulus one.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.
