Demonstration of Advanced Timing Schemes in Time-Resolved X-ray Diffraction Measurements
Daniel Schmidt, David. v. Stetten, Michael Agthe +5
We present time-resolved X-ray diffraction measurements using advanced timing schemes that provide high temporal resolution while also maintaining a high flux in the X-ray probe be…
Understanding Knowledge Gaps in Visual Question Answering: Implications for Gap Identification and Testing
Goonmeet Bajaj, Bortik Bandyopadhyay, Daniel Schmidt +3
Visual Question Answering (VQA) systems are tasked with answering natural language questions corresponding to a presented image. Traditional VQA datasets typically contain question…
Anisotropic Bruggeman Effective Medium Approaches for Slanted Columnar Thin Films
Daniel Schmidt, Mathias Schubert
Two different formalisms for the homogenization of composite materials containing ellipsoidal inclusions based on Bruggeman's original formula for spherical inclusions can be found…
Quantification of 242Pu with a Microcalorimeter Gamma Spectrometer
David J. Mercer, Ryan Winkler, Katrina E. Koehler +18
We report measurements of the 103-keV and 159-keV gamma ray signatures of 242Pu using microcalorimetry. This is the first observation of these gamma rays in a non-destructive measu…
Oxygen passivation mediated tunability of trion and excitons in MoS
Pranjal Kumar Gogoi, Zhenliang Hu, Qixing Wang +10
Using wide spectral range in situ spectroscopic ellipsometry with systematic ultra high vacuum annealing and in situ exposure to oxygen, we report the complex dielectric function o…
Curvature-induced Resolution of Anti-brane Singularities
Daniel Junghans, Daniel Schmidt, Marco Zagermann
We study AdS vacua of massive type IIA string theory compactified on a 3-sphere with flux and anti-D6-branes. In such backgrounds, the anti-brane backreaction is known to…
