Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

On the discrete logarithm problem for plane curves [PDF]

Journal de théorie des nombres de Bordeaux, 2012
In this article the discrete logarithm problem in degree 0 class groups of curves over finite fields given by plane models is studied. It is proven that the discrete logarithm problem for non-hyperelliptic curves of genus 3 (given by plane models of degree 4) can be solved in an expected time of

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

On the complexity of the discrete logarithm and Diffie–Hellman problems

Journal of Complexity, 2004
The discrete logarithm problem (DLP): given an element \(a\) in a cyclic group \(G=\langle g\rangle\) of order \(n\) find the unique integer \(x\),\,\, \(0\leq x \leq n-1\) such that \(a = g^x\), is widely believed to be a computationally hard problem. It was proposed as a one-way function for use in public-key cryptography in the foundational paper of

Discrete logarithm problem on elliptic curves over finite fields [PDF]

, 2022
The main focus of this thesis is the so-called elliptic curve discrete logarithm problem. The statement of the problem is that given a point P and a k-multiple of P on an elliptic curve defined over a finite field, can we recover k?

Integrated Field‐Free SOT Domain‐Wall Synapses and MTJ Stochastic Neurons for Hardware Boltzmann Machines

Advanced Functional Materials, EarlyView.
Field‐free spin‐orbit torque domain‐wall synapses integrated with stochastic MTJ neurons enable compact hardware Boltzmann machines. Leveraging intrinsic stochasticity and multi‐level conductance, the system achieves efficient probabilistic learning with high accuracy, demonstrating a scalable spintronic platform for energy‐efficient edge AI.
