An Implantable Piezofilm Middle Ear Microphone: Performance in Human Cadaveric Temporal Bones

no code implementations22 Dec 2023 John Z. Zhang, Lukas Graf, Annesya Banerjee, Aaron Yeiser, Christopher I. McHugh, Ioannis Kymissis, Jeffrey H. Lang, Elizabeth S. Olson, Hideko Heidi Nakajima

The equivalent input noise (0. 1-10 kHz) of the DrumMic and amplifier referenced to the ear canal was measured to be 54 dB SPL and estimated to be 46 dB SPL after accounting for the pressure gain of the outer ear.

Machine-Learned Prediction Equilibrium for Dynamic Traffic Assignment

1 code implementation14 Sep 2021 Lukas Graf, Tobias Harks, Kostas Kollias, Michael Markl

We study a dynamic traffic assignment model, where agents base their instantaneous routing decisions on real-time delay predictions.

Berezinskii-Kosterlitz-Thouless transition in the type-I Weyl semimetal PtBi$_2$

no code implementations5 Jan 2021 Arthur Veyrat, Valentin Labracherie, Rohith Acharya, Dima L. Bashlakov, Federico Caglieris, Jorge I. Facio, Grigory Shipunov, Lukas Graf, Johannes Schoop, Yurii Naidyuk, Romain Giraud, Jeroen van den Brink, Bernd Büchner, Christian Hess, Saicharan Aswartham, Joseph Dufouleur

Transport measurements show an unusually robust low dimensional superconductivity in thin exfoliated flakes up to 126 nm in thickness (with $T_c \sim 275-400$~mK), which constitutes the first report and study of unambiguous superconductivity in a type-I Weyl semimetal.

A Finite Time Combinatorial Algorithm for Instantaneous Dynamic Equilibrium Flows

no code implementations15 Jul 2020 Lukas Graf, Tobias Harks

In particular, all existence results and computational methods are based on fixed-point theorems and numerical discretization schemes and no exact finite time algorithm for equilibrium computation is known to date.
