Pushing high angular resolution and high contrast observations on the VLTI from Y to L band with the Asgard instrumental suite: integration status and plans
Marc-Antoine Martinod, Michael J. Ireland, Denis Defrère +39
ESO's VLTI has a history of record-breaking discoveries in astrophysics using high-angular resolution instrumentation. Its latest visitor instrument, the Asgard instrumental suite,…
Status and performance of the Asgard/NOTT cold nulling camera
P. Chingaipe, G. Medgyesi, A. Mazzoli +25
Long-baseline nulling interferometry suppresses the on-axis light of a star, enabling high-contrast observations of faint circumstellar emission and exoplanets at high angular reso…
A data structure for monomial ideals with applications to signature Gröbner bases
Pierre Lairez, Rafael Mohr, Théo Ternier
We introduce monomial divisibility diagrams (MDDs), a data structure for monomial ideals that supports insertion of new generators and fast membership tests. MDDs stem from a canon…
Access to Klein Tunneling via Space-Time Modulation
Furkan Ok, Amir Bahrami, Christophe Caloz
We show that space-time modulation of electromagnetic potentials enables Klein tunneling far below the static threshold. The derived kinematics reveal oblique transitions that can…
A cryogenic Paul trap for probing the nuclear isomeric excited state Th
Daniel Moritz, Kevin Scharl, Markus Wiesinger +16
While laser excitation of the nuclear isomeric transition in Th has been recently achieved for thorium atoms embedded in large-bandgap crystals, laser excitation and charac…
Paper-folding models for the CAR algebra
Grigoris Kopsacheilis, Wilhelm Winter
We show that the CAR algebra admits a Cantor spectrum C*-diagonal that is not conjugate to the standard AF diagonal. We obtain this by classification theory of C*-algebras, and the…
The Case for Contextual Copyleft: Licensing Open Source Training Data and Generative AI
Grant Shanklin, Emmie Hine, Claudio Novelli +2
The proliferation of generative AI systems has created new challenges for the Free and Open Source Software (FOSS) community, particularly regarding how traditional copyleft princi…
Simultaneous Network Design with Restricted Link Usage
Naonori Kakimura, Péter Madarasi, Jannik Matuschke +1
Given a digraph with two terminal vertices and as well as a conservative cost function and several not necessarily disjoint color classes on its arc set, our goal is to fin…
Fundamental Understanding of Exposure and Process Chemistry for Enhanced Lithography and Stability of Metal Oxide Resists
Kevin M. Dorney, Ivan Pollentier, Fabian Holzmeier +11
Metal oxide resists (MORs) have shown great promise for high resolution patterning in extreme ultraviolet (EUV) lithography, with potential for integration into high volume manufac…
Unraveling the Reaction Mechanisms in a Chemically Amplified EUV Photoresist from a Combined Theoretical and Experimental Approach
Laura Galleni, Dhirendra P. Singh, Thierry Conard +5
Extreme ultraviolet (EUV) lithography has revolutionized high-volume manufacturing of nanoscale components, enabling the production of smaller, denser, and more energy efficient in…
Novel Concept-Oriented Synthetic Data approach for Training Generative AI-Driven Crystal Grain Analysis Using Diffusion Model
Ahmed Sobhi Saleh, Kristof Croes, Hajdin Ceric +2
The traditional techniques for extracting polycrystalline grain structures from microscopy images, such as transmission electron microscopy (TEM) and scanning electron microscopy (…
Chemistry and ro-vibrational excitation of HeH in the Planetary Nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
HeH belongs to the class of "reactive" ions that can be destroyed so quickly that chemical formation and destruction rates may compete with inelastic rates and should be consid…
Generative Kernel Spectral Clustering
David Winant, Sonny Achten, Johan A. K. Suykens
Modern clustering approaches often trade interpretability for performance, particularly in deep learning-based methods. We present Generative Kernel Spectral Clustering (GenKSC), a…
Stoichiometry and Thickness of Epitaxial SrTiO on Silicon (001): an Investigation of Physical, Optical and Electrical Properties
Andries Boelen, Marina Baryshnikova, Anja Ulrich +4
Strontium titanate (SrTiO, STO) stands out as a promising material for various electronic applications thanks to its exceptional dielectric properties. Molecular beam epitaxy…
Using dynamic loss weighting to boost improvements in forecast stability
Daan Caljon, Jeff Vercauteren, Simon De Vos +2
Rolling origin forecast instability refers to variability in forecasts for a specific period induced by updating the forecast when new data points become available. Recently, an ex…
Finding Closure: A Closer Look at the Gestalt Law of Closure in Convolutional Neural Networks
Yuyan Zhang, Derya Soydaner, Lisa Koßmann +2
The human brain has an inherent ability to fill in gaps to perceive figures as complete wholes, even when parts are missing or fragmented. This phenomenon is known as Closure in ps…
VLTI Unit Telescope coudé train vibration control upgrade for GRAVITY+
Romain Laugier, Julien Woillez, Denis Defrère +15
Scaling up interferometry to 8m collectors should smooth-out the optical piston perturbations and allow a slow fringe tracker to obtain high precision correction on faint targets.…
Asgard/NOTT: First lab assembly and experimental results
G. Garreau, A. Bigioli, R. Laugier +17
Asgard/NOTT is an ERC-funded project hosted at KU Leuven and is part of a new visitor instrumental suite, called Asgard, under preparation for the Very Large Telescope Interferomet…
Single-cell 3D genome reconstruction in the haploid setting using rigidity theory
Sean Dewar, Georg Grasegger, Kaie Kubjas +2
This article considers the problem of 3-dimensional genome reconstruction for single-cell data, and the uniqueness of such reconstructions in the setting of haploid organisms. We c…
Understanding overfitting in random forest for probability estimation: a visualization and simulation study
Lasai Barreñada, Paula Dhiman, Dirk Timmerman +2
Random forests have become popular for clinical risk prediction modelling. In a case study on predicting ovarian malignancy, we observed training c-statistics close to 1. Although…
YOLOv8 for Defect Inspection of Hexagonal Directed Self-Assembly Patterns: A Data-Centric Approach
Enrique Dehaerne, Bappaditya Dey, Hossein Esfandiar +4
Shrinking pattern dimensions leads to an increased variety of defect types in semiconductor devices. This has spurred innovation in patterning approaches such as Directed self-asse…
Electron Scattering at a Potential Temporal Step Discontinuity
