Journal of Approximation Theory, 2010 An algebraic polynomial that has all its zeros in a finite interval \([a,b]\) is called oscillating on \([a,b]\). In the present paper the authors prove the following Theorem. Let \(P\) be an oscillating on \([-1,1]\) polynomial of degree \(n\) with symmetric zeros, and let \(P\) attain its maximal absolute value at the endpoints.

Advanced Materials Technologies, EarlyView.The dual‐gate coplanar a‐IGZO/C‐IGO/a‐IGZO TFT is investigated, exhibiting a high filed‐effect mobility of 53.81 cm2 V−1s−1 with excellent stability. The amorphous IGZO layer provides smooth surface, which carrier scattering and high‐quality interface between gate insulator and active layer.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling
Advanced Optical Materials, EarlyView.Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

Improvement of the Barkhausen criterion and the implementation of an intelligent function generator
The Journal of Engineering, 2017 Function generators are vital tools for many industrial applications. Sinusoidal oscillators are the essential units of function generators and investigating their performance is therefore necessary.
