Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components
Advanced Engineering Materials, EarlyView.This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

Powder Metallurgy Preparation of Metastable β Ti–Cr–Ge Alloys for Medical Applications
Advanced Engineering Materials, EarlyView.This study develops metastable β Ti–Cr–Ge alloys using powder metallurgy for biomedical implants. The Ti–10Cr–2Ge alloy exhibits superior mechanical performance with high yield strength (>1100 MPa), low Young's modulus (<85 GPa), and excellent strain hardening behavior.

A completely monotonic function involving the gamma and trigamma functions
Kuwait Journal of Science, 2016 In the paper the author provides necessary and sufficient conditions on $a$ for the function\begin{equation*}\frac{1}{2}\ln(2\pi)-x+\biggl(x-\frac{1}{2}\biggr)\ln x-\ln\Gamma(x)+\frac1{12}{\psi'(x+a)}\end{equation*}and its negative to be completely ...

On a Functional Equation Appearing on the Margins of a Mean Invariance Problem
Annales Mathematicae Silesianae, 2020 Given a continuous strictly monotonic real-valued function α, defined on an interval I, and a function ω : I → (0, +∞) we denote by Bαω the Bajraktarević mean generated by α and weighted by ω:

Advanced Engineering Materials, EarlyView.In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

The incoherent feed‐forward loop can generate non‐monotonic input functions for genes
Molecular Systems Biology, 2008 Gene regulation networks contain recurring circuit patterns called network motifs. One of the most common network motif is the incoherent type 1 feed‐forward loop (I1‐FFL), in which an activator controls both gene and repressor of that gene.

On-Line AdaTron Learning of Unlearnable Rules
, 1997 We study the on-line AdaTron learning of linearly non-separable rules by a simple perceptron. Training examples are provided by a perceptron with a non-monotonic transfer function which reduces to the usual monotonic relation in a certain limit.

On nowhere monotone functions [PDF]
Proceedings of the American Mathematical Society, 1976 The existence of everywhere differentiable but nowhere monotone functions is established using the Baire Category Theorem, and the relatively easy fact that there are nontrivial bounded derivatives with a dense set of zeros.

Advanced Engineering Materials, EarlyView.Fe–12Mn–0.2C medium‐manganese steel is processed by laser‐based powder bed fusion of metals using blended as well as pre‐alloyed powder. Various scanning speeds are used to determine the influence of energy deposition rate on microstructure and mechanical properties.

Journal of Inequalities and Applications, 2011 We prove that the function F α,β (x) = x α Γ β (x)/Γ(βx) is strictly logarithmically completely monotonic on (0, ∞) if and only if (α, β) ∈ {(α, β) : β > 0, β ≥ 2 ...
