Familiarity: Better Evaluation of Zero-Shot Named Entity Recognition by Quantifying Label Shifts in Synthetic Training Data

Autor: Golde, Jonas, Haller, Patrick, Ploner, Max, Barth, Fabio, Jedema, Nicolaas, Akbik, Alan

Zero-shot named entity recognition (NER) is the task of detecting named entities of specific types (such as 'Person' or 'Medicine') without any training examples. Current research increasingly relies on large synthetic datasets, automatically generat

A Broad-line, Low-luminosity Active Galactic Nucleus at ${z=7.3}$ Anchoring a Large Galaxy Overdensity

Autor: Schindler, Jan-Torge, Hennawi, Joseph F., Davies, Frederick B., Bosman, Sarah E. I., Endsley, Ryan, Wang, Feige, Yang, Jinyi, Barth, Aaron J., Eilers, Anna-Christina, Fan, Xiaohui, Kakiichi, Koki, Maseda, Michael, Pizzati, Elia, Nanni, Riccardo

The James Webb Space Telescope has uncovered a puzzling population of UV-faint broad-line active galactic nuclei (AGN), nicknamed ``Little Red Dots'' (LRD) owing to their compact morphology and red rest-frame optical colours. Interpreted as dust atte

Anomalous conductance steps in 3D TI HgTe-based quantum point contacts

Autor: Richter, Elisabeth, Barth, Michael, Kozlov, Dmitriy A., Knothe, Angelika, Mikhailov, Nikolay N., Steidl, Juliane, Gorini, Cosimo, Hartl, Stefan, Himmler, Wolfgang, Richter, Klaus, Weiss, Dieter

We explore electrical transport through a point contact in strained HgTe, a three-dimensional topological insulator. In the absence of a magnetic field $B$, there is no quantization. However, under higher magnetic fields, we observe distinct non-inte

The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable $x$, the relative virtual-photon energy $y$ and the fraction of the virtual-p
