Effect of High-Temperature Heat Treatment on the Acoustic-Vibration Performance of Picea jezoensis
The crystallinity and acoustic-vibration parameters of Picea jezoensis, including specific Young’s modulus (E/ρ),coefficient of sound-radiation resistance (R), sound resistance (ω), and the ratio of Young’s modulus to the dynamic stiffness modulus (E/G),

On the maximum modulus of polynomials
The reviewed paper contains some extensions of the inequalities concerning the modulus of the polynomial taken on different circles. For example: if \(p(z)=\sum^{n}_{k=1}a_ kz^ k\) is a polynomial of degree n, having no zeros in \(| z|

Blind joint maximum likelihood channel estimation and data detection for SIMO systems
A blind adaptive scheme is proposed for joint maximum likelihood (ML) channel estimation and data detection of single-input multiple-output (SIMO) systems. The joint ML optimisation over channel and data is decomposed into an iterative optimisation loop.

A sub-Riemannian maximum modulus theorem [PDF]
In this note we prove a sub-Riemannian maximum modulus theorem in a Carnot group. Using a nontrivial counterexample, we also show that such result is best possible, in the sense that in its statement one cannot replace the right-invariant horizontal ...

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.
