EGAIN: Extended GAn INversion
Wassim Kabbani, Marcel Grimmer, Christoph Busch
Generative Adversarial Networks (GANs) have witnessed significant advances in recent years, generating increasingly higher quality images, which are non-distinguishable from real o…
Misclassification excess risk bounds for 1-bit matrix completion
The Tien Mai
This study investigates the misclassification excess risk bound in the context of 1-bit matrix completion, a significant problem in machine learning involving the recovery of an un…
Tuning the Josephson diode response with an ac current
Rubén Seoane Souto, Martin Leijnse, Constantin Schrade +3
Josephson diodes are superconducting elements that show an asymmetry in the critical current depending on the direction of the current. Here, we theoretically explore how an altern…
Collective Strong Coupling Modifies Aggregation and Solvation
Matteo Castagnola, Tor S. Haugland, Enrico Ronca +2
Intermolecular interactions are pivotal for aggregation, solvation, and crystallization. We demonstrate that the collective strong coupling of several molecules to a single optical…
Examining the Effect of Implementation Factors on Deep Learning Reproducibility
Kevin Coakley, Christine R. Kirkpatrick, Odd Erik Gundersen
Reproducing published deep learning papers to validate their conclusions can be difficult due to sources of irreproducibility. We investigate the impact that implementation factors…
Scalar Product for a Version of Minisuperspace Model with Grassmann Variables
Sergey L. Cherkas, Vladimir L. Kalashnikov
Grassmann variables are used to formally transform a system with constraints into an unconstrained system. As a result, the Schrödinger equation arises instead of the Wheeler-DeWit…
Conditionally monotone cumulants via shuffle algebra
Adrian Celestino, Kurusch Ebrahimi-Fard
In this work we study conditional monotone cumulants and additive convolution in the shuffle-algebraic approach to non-commutative probability. We describe c-monotone cumulants as…
Where Did the Amaterasu Particle Come From?
Michael Unger, Glennys R. Farrar
The Telescope Array Collaboration recently reported the detection of a cosmic-ray particle, "Amaterasu", with an extremely high energy of eV. Here we investigate…
High-dimensional sparse classification using exponential weighting with empirical hinge loss
The Tien Mai
In this study, we address the problem of high-dimensional binary classification. Our proposed solution involves employing an aggregation technique founded on exponential weights an…
Empirical model of SSUSI-derived auroral ionization rates
Stefan Bender, Patrick J. Espy, Larry J. Paxton
We present an empirical model for auroral (90--150 km) electron--ion pair production rates, ionization rates for short, derived from SSUSI (Special Sensor Ultraviolet Spectrographi…
Topological magnon gap engineering in van der Waals CrI ferromagnets
Verena Brehm, Pawel Sobieszczyk, Jostein Kløgetvedt +3
The microscopic origin of the topological magnon band gap in CrI ferromagnets has been a subject of controversy for years since two main models with distinct characteristics, i…
Learning of Hamiltonian Dynamics with Reproducing Kernel Hilbert Spaces
Torbjørn Smith, Olav Egeland
This paper presents a method for learning Hamiltonian dynamics from a limited set of data points. The Hamiltonian vector field is found by regularized optimization over a reproduci…
Position operators and interband matrix elements of scalar and vector potentials in the 8-band Kane model
I. A. Ado, M. Titov, Rembert A. Duine +1
We diagonalize the 8-band Kane Hamiltonian with a proper inclusion of the interband matrix elements of the scalar and vector potentials. This leads, among other results, to a modif…
Twisted Spectra Revisited
Alice Hedenlund, Tasos Moulinos
We recapture Douglas' framework for twisted parametrized stable homotopy theory in the language of - categories. A twisted spectrum is essentially a section of a bundle of…
RMS: Redundancy-Minimizing Point Cloud Sampling for Real-Time Pose Estimation
Pavel Petracek, Kostas Alexis, Martin Saska
The typical point cloud sampling methods used in state estimation for mobile robots preserve a high level of point redundancy. This redundancy unnecessarily slows down the estimati…
Non-constant geometric curvature for tailored spin-orbit coupling and chirality in superconductor-magnet heterostructures
Alv Johan Skarpeid, Henning G. Hugdal, Tancredi Salamone +2
We show that tailoring the geometric curvature profile of magnets can be used for bespoke design of an effective non-relativistic spin-orbit coupling, which may be used to control…
Equivalence of entropy solutions and gradient flows for pressureless 1D Euler systems
José Antonio Carrillo, Sondre Tesdal Galtung
We study distributional solutions of pressureless Euler systems on the line. In particular we show that Lagrangian solutions, introduced by Brenier, Gangbo, Savaré and Westdickenbe…
Design and Implementation of a Hybrid Wireless Power and Communication System for Medical Implants
A. Khaleghi, A. Hasanvand, I. Balasingham
Data collection and analysis from multiple implant nodes in humans can provide targeted medicine and treatment strategies that can prevent many chronic diseases. This data can be c…
Biases from spectral leakage in remote sensing of near-surface currents
Stefan Weichert, Benjamin K. Smeltzer, Simen Å. Ellingsen
Remotely measuring subsurface water currents from imagery of the wave field has become a much-used technique. We study the biases and errors in such measurements due to spectral le…
Log-Likelihood Score Level Fusion for Improved Cross-Sensor Smartphone Periocular Recognition
Fernando Alonso-Fernandez, Kiran B. Raja, Christoph Busch +1
The proliferation of cameras and personal devices results in a wide variability of imaging conditions, producing large intra-class variations and a significant performance drop whe…
The Coherent Magnetic Field of the Milky Way
Michael Unger, Glennys R. Farrar
We present a suite of models of the coherent magnetic field of the Galaxy (GMF) based on new divergence-free parametric functions describing the global structure of the field. The…
Interface probe for antiferromagnets using geometric curvature
Tancredi Salamone, Magnus Skjærpe, Henning G. Hugdal +2
We propose that geometric curvature and torsion may be used to probe the quality of an uncompensated antiferromagnetic interface, using the proximity effect. We study a helix of an…
Chasing the break: Tracing the full evolution of a black hole X-ray binary jet with multi-wavelength spectral modeling
Constanza Echiburú-Trujillo, Alexandra J. Tetarenko, Daryl Haggard +35
Black hole X-ray binaries (BH XRBs) are ideal targets to study the connection between accretion inflow and jet outflow. Here we present quasi-simultaneous, multi-wavelength observa…
