Wital: A COTS WiFi Devices Based Vital Signs Monitoring System Using NLOS Sensing Model

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Yu Gu, Huan Yan, Yantong Wang, Mianxiong Dong | Summary: Vital sign (breathing and heartbeat) monitoring is essential for patient care and sleep disease prevention. Most current solutions are based on wearable sensors or cameras; however, the former could affect sleep quality, while the latter […]

Detecting, distinguishing, and spatiotemporally tracking photogenerated charge and heat at the nanoscale

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Hannah L. Weaver, Cora M. Went, Joeson Wong, Dipti Jasrasaria, Eran Rabani | Summary: Since dissipative processes are ubiquitous in semiconductors, characterizing how electronic and thermal energy transduce and transport at the nanoscale is vital for understanding and leveraging their fundamental properties. For example, in low-dimensional […]

Incomplete inverse problem for Dirac operator with constant delay

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than two-fifths of the interval and not less than one-third of the interval. For our considered Dirac-type operators, an incomplete inverse spectral problem is studied. Specifically, when two complex […]

Inverse problems for Dirac operators with a constant delay less than half of the interval

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than half of the interval and not less than two fifths of the interval. For our considered Dirac-type operators, an inverse spectral problem is studied. Specifically, reconstruction of two […]

Improved Bounds for Single-Nomination Impartial Selection

Kavli Affiliate: Felix Fischer | First 5 Authors: Javier Cembrano, Felix Fischer, Max Klimm, , | Summary: We give new bounds for the single-nomination model of impartial selection, a problem proposed by Holzman and Moulin (Econometrica, 2013). A selection mechanism, which may be randomized, selects one individual from a group of $n$ based on nominations […]

Breakdown of helical edge state topologically protected conductance in time-reversal-breaking excitonic insulators

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yan-Qi Wang, Michał Papaj, Joel E. Moore, , | Summary: Gapless helical edge modes are a hallmark of the quantum spin Hall effect. Protected by time-reversal symmetry, each edge contributes a quantized zero-temperature conductance quantum $G_0 equiv e^2/h$. However, the experimentally observed conductance in WTe$_2$ decreases […]
