Understanding and Designing Avatar Biosignal Visualizations for Social Virtual Reality EntertainmentLee, Sueyoon (author), El Ali, Abdallah (author), Wijntjes, M.W.A. (author), Cesar, Pablo (author)Visualizing biosignals can be important for social Virtual Reality (VR), where avatar non-verbal cues are missing. While several biosignal representations exist, designing effective visualizations and understanding user perceptions within social VR entertainment remains unclear. We adopt a mixed-methods approach to design biosignals for...conference paper 2022

WANG, J. (author), Schrade, Constantin (author), Levajac, V. (author), van Driel, D. (author), Li, K. (author), Badawy, G.H.A. (author), Lee, J.S. (author), Kouwenhoven, Leo P. (author), Shen, Jie (author)We study a Cooper pair transistor realized by two Josephson weak links that enclose a superconducting island in an InSb-Al hybrid nanowire. When the nanowire is subject to a magnetic field, isolated subgap levels arise in the superconducting island and, because of the Coulomb blockade, mediate a supercurrent by coherent cotunneling of Cooper...journal article 2022

Lee, Y. (author), Chen, H. (author), Zhao, Guoying (author), Specht, M.M. (author)Human attention is critical yet challenging cognitive process to measure due to its diverse definitions and non-standardized evaluation. In this work, we focus on the attention self-regulation of learners, which commonly occurs as an effort to regain focus, contrary to attention loss. We focus on easy-to-observe behavioral signs in the real...conference paper 2022

Baars, W.J. (author), Lee, Myoungkyu (author)Since wall-pressure fluctuations would form a practically-robust input to a real-time active controller of wall-bounded turbulence, it is of high practical interest to study the scaling behavior of the wall-pressure-velocity coupling. This work investigates the coupling of the wall-pressure fluctuations with the streamwise and wall-normal...conference paper 2022

Lee, Jaejin (author), Kim, S.H. (author), Se, Tola (author), Kim, Doseok (author)Single-molecule fluorescence experiments allow monitoring of the structural change and dynamics of a single biomolecule in real time using dye molecules attached to the molecule. Often, the molecules are immobilized on the surface to observe a longer molecular dynamics, yet the finite photon budget available from an individual dye molecule...journal article 2022

Seo, Miri (author), Yang, Eunseo (author), Shin, D. (author), Je, Yugyeong (author), Joo, C. (author), Lee, Kookjin (author), Lee, Sang Wook (author)Nanomechanical resonator devices are widely used as ultrasensitive mass detectors for fundamental studies and practical applications. The resonance frequency of the resonators shifts when a mass is loaded, which is used to estimate the mass. However, the shift signal is often blurred by the thermal noise, which interferes with accurate mass...journal article 2022

Panthi, Manisha (author), Lee, Aaron A. (author), Dahal, Sudesh (author), Omer, Amgad (author), Franca, M.J. (author), Crosato, A. (author)Flushing is a common measure to manage and reduce the amount of sediment stored in reservoirs. However, the sudden release of large volumes of sediment abruptly increases the suspended solids concentration and alters the riverbed composition. Similar effects can be produced also by natural flood events. Do flushing operations have more...journal article 2022

Multi-objective design of aircraft maintenance using Gaussian process learning and adaptive samplingLee, J. (author), Mitici, M.A. (author)Aircraft maintenance design aims to identify strategies that render the aircraft reliable for flight in a cost-efficient manner. These are often conflicting objectives. Moreover, existing studies on maintenance design often limit themselves to only one type of maintenance strategy, overlooking other potentially dominating designs. We propose...journal article 2022

(author)Although 2D materials hold great potential for next-generation pressure sensors, recent studies revealed that gases permeate along the membrane-surface interface, necessitating additional sealing procedures. In this work, we demonstrate the use of free-standing complex oxides as self-sealing membranes that allow the reference cavity beneath...journal article 2022

Jeon, Jaemin (author), Kim, Jaeyong (author), Lee, Jong Jun (author), Shin, D. (author), Kim, Yoon Young (author)This study presents a new modeling technique to estimate the stiffness matrix of a thin-walled beam-joint structure using deep learning. When thin-walled beams meet at joints, significant sectional deformations occur, such as warping and distortion. These deformations should be considered in the one-dimensional beam analysis, but it is...journal article 2022
