X-ray measurements of gas distribution in a zero gap alkaline water electrolyzer

Autor: Dung, On-Yu, Boden, Stephan, Vreman, Albertus W., Deen, Niels G., Schubert, Markus, Tang, Yali

X-ray radioscopy was used to measure the 2D projected dynamic void fraction in a zero/narrow gap alkaline water electrolyzer at a spatial resolution of 15 $\mu$m, for narrow gap sizes up to 300 $\mu$m and current densities up to 0.54 A/cm$^2$. As exp

LLMCount: Enhancing Stationary mmWave Detection with Multimodal-LLM

Autor: Li, Boyan, Ding, Shengyi, Ma, Deen, Wu, Yixuan, Liao, Hongjie, Hu, Kaiyuan

Millimeter wave sensing provides people with the capability of sensing the surrounding crowds in a non-invasive and privacy-preserving manner, which holds huge application potential. However, detecting stationary crowds remains challenging due to sev

Fast and accurate log-determinant approximations

Autor: Deen, Owen, Waller, Colton River, Ward, John Paul

We consider the problem of estimating log-determinants of large, sparse, positive definite matrices. A key focus of our algorithm is to reduce computational cost, and it is based on sparse approximate inverses. The algorithm can be implemented to be

Characterizing the diffuse continuum excitations in the classical spin liquid $h$-YMnO$_3$

Autor: Lass, Jakob, Lenander, Emma Y., Krighaar, Kristine M. L., Tošić, Tara N., Prabhakaran, Dharmalingam, Deen, Pascale P., Holm-Janas, Sofie, Lefmann, Kim

We extend previous inelastic neutron scattering results on the geometrically frustrated antiferromagnet hexagonal-YMnO$_3$, which has been suggested to belong to the class of classical spin liquids. We extend the energy transfer coverage of the diffu

A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigonometric parallax determinations from Gaia, ground-based surveys, and
