lrSVD: An efficient imputation algorithm for incomplete high‐throughput compositional data

open access: yesJournal of Chemometrics, Volume 36, Issue 12, December 2022., 2022
Abstract Compositional methods have been successfully integrated into the chemometric toolkit to analyse and model different types of data generated by modern high‐throughput technologies. Within this compositional framework, the focus is put on the relative information conveyed in the data by using log‐ratio coordinate representations.

Lattice-Based Generation of Euclidean Geometry Figures

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
We present a user-guided method to generate geometry figures appropriate for high school Euclidean geometry courses: a useful starting point for an intelligent tutoring system to provide meaningful, realistic figures for study.

From Tarski to Descartes: Formalization of the Arithmetization of Euclidean Geometry

open access: yesInternational Symposium on Symbolic Computation in Software Science, 2016
This paper describes the formalization of the arithmetization of Euclidean geometry in the Coq proof assistant. As a basis for this work, Tarski's system of geometry was chosen for its well-known metamathematical properties.

From Free Fields to AdS -- Thermal Case

open access: yes, 2005
We analyze the reorganization of free field theory correlators to closed string amplitudes investigated in hep-th/0308184 hep-th/0402063 hep-th/0409233 hep-th/0504229 in the case of Euclidean thermal field theory and study how the dual bulk geometry is ...

A comparative analysis of deep learning architectures with data augmentation and multichannel input for locoregional breast cancer radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Studies on deep learning dose prediction increasingly focus on 3D models with multiple input channels and data augmentation, which increases the training time and thus also the environmental burden and hampers the ease of re‐training. Here we compare 2D and 3D U‐Net models with clinical accepted plans to evaluate the appropriateness of

Uptunneling to de Sitter

open access: yesJournal of High Energy Physics, 2020
We propose a Euclidean preparation of an asymptotically AdS2 spacetime that contains an inflating dS2 bubble. The setup can be embedded in a four dimensional theory with a Minkowski vacuum and a false vacuum.

Position‐dependent offset corrections for ring applicator reconstruction in cervical cancer brachytherapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Due to the tight curvature in their design, ring applicators are usually associated with large positioning errors. The standard practice to correct for these deviations based on global offsets may not be sufficient to comply with the recommended tolerance.
