Algorithms for Exponentiation in Finite Fields
Let \(q\) be a prime power, and let \(r=nk+1\) be a prime not dividing \(q\). Let \(e\) be the index of the subgroup generated by \(q\) in the multiplicative group \(\mathbb Z ^*_r=\mathbb Z _r \setminus \{0\}\), and let \(K\) be the unique subgroup of order \(k\) in \(\mathbb Z ^*_r\). Let \(\beta\) be a primitive \(r\)th root of unity in GF\((q^{nk})\

A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

On the Maximum Probability of Full Rank of Random Matrices over Finite Fields
The problem of determining the conditions under which a random rectangular matrix is of full rank is a fundamental question in random matrix theory, with significant implications for coding theory, cryptography, and combinatorics. In this paper, we study

Isomorphism classes of elliptic and hyperelliptic curves over finite fields F((2g+1))n
We give the number and representatives of isomorphism classes of hyperelliptic curves of genus g defined over finite fields F-(2g+1)(n), g = 1, 2, 3. These results have applications to hyperelliptic curve cryptography. (C) 2004 Elsevier Inc.
