Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

A New Trick for Polynomial Multiplication

Transactions on Cryptographic Hardware and Embedded Systems
In this paper we present a novel transformation strategy for polynomial multiplications and apply it to NTRU Prime, specifically the parameter sets sntrup761 and ntrulpr761 working in the ring Z4591[x]/⟨x761−x−1⟩.

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation

Advanced Engineering Materials, EarlyView.
A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

Simple Multivariate Polynomial Multiplication

Journal of Symbolic Computation, 1994
Let \(u= u(x_1, \dots, x_m)\) and \(v= v(x_1, \dots, x_m)\) be \(m\)-variate polynomials over a field \(F\) and let \(N= c^m\), where \(c\) is chosen so that \(c\geq 2\deg_{x_i} (u)+ 1,2 \deg_{x_i} (v)+ 1\) \((1\leq i\leq m)\). It is known that the product \(uv\) can be computed in time \(O(N \log N\log \log N)\).

On Hyperbolic Polynomials with Multiple Roots [PDF]

Proceedings of the American Mathematical Society, 1969
Let Q(z) Q(z, **, zn) be a polynomial of degree m > 1 in Z(Zl, , * Zn) with complex coefficients. Let P(z) be the principal part, homogeneous of degree m. Q is defined to be hyperbolic with respect to the real vector t-(4, , n) $0, in the sense of Garding [1], if P(t)z0 and if there exists a real number to such that for Re r> to, and all real vectors 7,

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.
