Suppression of pair beam instabilities in a laboratory analogue of blazar pair cascades
Charles D. Arrowsmith, Francesco Miniati, Pablo J. Bilbao +28
The generation of dense electron-positron pair beams in the laboratory can enable direct tests of theoretical models of -ray bursts and active galactic nuclei. We have successfu…
From Capabilities to Performance: Evaluating Key Functional Properties of LLM Architectures in Penetration Testing
Lanxiao Huang, Daksh Dave, Tyler Cody +2
Large language models (LLMs) are increasingly used to automate or augment penetration testing, but their effectiveness and reliability across attack phases remain unclear. We prese…
Hierarchical Scoring for Machine Learning Classifier Error Impact Evaluation
Erin Lanus, Daniel Wolodkin, Laura J. Freeman
A common use of machine learning (ML) models is predicting the class of a sample. Object detection is an extension of classification that includes localization of the object via a…
DARHT Axis 1 Compensation Can D-dot Calibration
J. Martin Taccetti, Darin Westley, Jeffrey B. Johnson +1
We detail the calibration of the D-dot probes used on the Los Alamos National Laboratory DARHT Axis 1 LIA compensation cans (CCs). We hope this will serve not only as a record of t…
Improved Probabilistic Principal Component Analysis for Application to Reduced Order Modeling
Indika Udagedara, Brian Helenbrook, Aaron Luttman +1
In our previous work, a reduced order model (ROM) for a stochastic system was made, where noisy data was projected onto principal component analysis (PCA)-derived basis vectors to…
Quantification and visualization of variation in anatomical trees
Nina Amenta, Manasi Datar, Asger Dirksen +9
This paper presents two approaches to quantifying and visualizing variation in datasets of trees. The first approach localizes subtrees in which significant population differences…
