Asymptotic Behavior of Functions with Bounded Boundary Rotation [PDF]

Transactions of the American Mathematical Society, 1972
Fork≧2k \geqq 2denote byVk{V_k}the class of normalized functions, analytic in the unit disc, which have boundary rotation at mostkπk\pi. Letan{a_n}be thenth Taylor coefficient off(z)∈Vkf(z) \in {V_k}. LetIλ(r,f′){I_\lambda }(r,f’)andIλ(r,f){I_\lambda }(r,f)be theλ\lambda-integral mean off′(z)f’(z)andf(z)f(z)respectively.

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Multi-quasiparticle structures up to spin $\sim{44}\hbar$ in the odd-odd nucleus $^{168}$Ta

, 2010
High-spin states in the odd-odd nucleus $^{168}$Ta have been populated in the $^{120}$Sn($^{51}$V,3n) reaction. Two multi-quasiparticle structures have been extended significantly from spin $\sim{20\hbar}$ to above ${40\hbar}$.

Efficient Process Development for Laser Powder Bed Fusion of a Soft‐Magnetic Metallic Glass Composite

Advanced Engineering Materials, EarlyView.
Iron‐based metallic glass alloys exhibit excellent soft‐magnetic properties, and unprecedented geometrical freedom in the design of soft‐magnetic metallic glass components is made possible by additive manufacturing. An efficient workflow for developing parameters for laser‐based powder bed fusion of a Fe‐based metallic glass alloy is presented along ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

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.

Auditor rotation behavior in Germany

Corporate Ownership and Control
The German legislator implements, among other auditor regulations, mandatory auditor rotation in order to contribute to the European objectives of higher auditor independence and audit market deconcentration. However, it is questionable how German firms will implement the mandatory auditor rotation within the statutory transition periods.
