Sharp bounds of logarithmic coefficient problems for functions with respect to symmetric points

Математичні Студії, 2023
The logarithmic coefficients play an important role for different estimates in the theory of univalent functions. Due to the significance of the recent studies about the logarithmic coefficients, the problem of obtaining the sharp bounds for the second ...

J/Psi and Psi' Suppression in Hadronic Matter

, 1995
We present a microscopic calculation of the breakup cross sections of $J/\psi$ and $\psi'$ on pions and nucleons as a function of the kinetic energy.

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

Advanced Engineering Materials, EarlyView.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

Fermion localization on asymmetric two-field thick branes

, 2010
In this paper we investigate the localization of fermions on asymmetric thick branes generated by two scalars $\phi$ and $\chi$. In order to trap fermions on the asymmetric branes with kink-like warp factors, the couplings with the background scalars ...

Ultrasonic Atomization Spray Coating of PCL on an Mg‐Based Alloy Enhanced by Plasma Electrolytic Oxidation for Improved Adhesion, Corrosion Resistance, and Biocompatibility

Advanced Engineering Materials, EarlyView.
Plasma electrolytic oxidation is combined with ultrasonic spray deposition of polycaprolactone (PCL) on WE43 magnesium alloy to improve adhesion, corrosion resistance, and cytocompatibility. The hybrid coating demonstrates significantly reduced hydrogen evolution and enhances mechanical bonding, offering a promising strategy for next‐generation ...

Encapsulating Laser‐Induced Graphene to Preserve its Electrical Properties and Enhance its Mechanical Robustness

Advanced Engineering Materials, EarlyView.
It is demonstrated that laser‐induced graphene (LIG) can be encapsulated while preserving its electrical conductivity and enhancing its mechanical properties. Unlike previous encapsulation attempts, the optimal conditions described here result in sheet resistance of ≈2 Ω sq−1, resistance increase of only 5% upon encapsulation, and vastly improved ...

Molecules as metric measure spaces with Kato-bounded Ricci curvature

Comptes Rendus. Mathématique, 2020
Set $\Psi :=\log (\tilde{\Psi })$, with $\tilde{\Psi }>0$ the ground state of an arbitrary molecule with $n$ electrons in the infinite mass limit (neglecting spin/statistics).

On the Riemann Hypothesis and the Dedekind Psi Function

, 2023
Let $N_n=2\cdot 3\cdots p_n$ be the primorial of order $n$ and $\Psi$ the Dedekind Psi function. Sol\'{e} and Planat (2011) proved that the Riemann Hypothesis is true if and only if $\Psi(N_n)/(N_n\log\log N_n)>e^\gamma/\zeta(2)$ for all $n\geq 3$.
