International Journal for Numerical Methods in Engineering, Volume 127, Issue 12, 30 June 2026.ABSTRACT Limit analysis and yield design provide a well‐defined mathematical framework for upscaling the strength properties of heterogeneous materials. These techniques can be incorporated into an FFT‐based computational micromechanics framework to evaluate the strength of heterogeneous materials, based on images of their microstructure.

Influence of Particle Aspect Ratio on Translational Collision Dynamics in Wall‐Bounded Turbulence
Chemical Engineering &Technology, Volume 49, Issue 6, June 2026.Direct numerical simulations with fully resolved four‐way coupling show that particle shape strongly influences collision dynamics in turbulent channel flow. Needle‐like ellipsoids align with local shear, reducing turbulent scattering and producing lower collision velocities with narrower impact‐angle distributions.

ON AN EXTREMAL PROBLEM FOR POLYNOMIALS WITH FIXED MEAN VALUE
Ural Mathematical Journal, 2016 Let \(T_n^+\) be the set of nonnegative trigonometric polynomials \(\tau_n\) of degree \(n\) that are strictly positive at zero. For \(0\le\alpha\le2\pi/(n+2),\) we find the minimum of the mean value of polynomial \((\cos\alpha-\cos{x})\tau_n(x)/\tau_n(0)

On the Gaps between Zeros of Trigonometric Polynomials
Real Analysis Exchange, 2003 We show that for every finite symetric set S of integer vectors, every real trigonometric polynomial on the d dimensional torus with spectrum in S has a zero in every closed ball of diameter D, where D is the sum over S of 1 over 4 times the L2 norm of the vector. We investigate tightness in some special cases.
