Kavli Affiliate: Wei Gao | First 5 Authors: Lingzhi Wang, Shafiq Joty, Wei Gao, Xingshan Zeng, Kam-Fai Wong | Summary: Conversational Recommender Systems (CRS) has become an emerging research topic seeking to perform recommendations through interactive conversations, which generally consist of generation and recommendation modules. Prior work on CRS tends to incorporate more external and […]

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yang Zhang, Joshua Olick-Gibson, Anjul Khadria, Lihong V. Wang, | Summary: Non-invasive imaging of deep blood vessels for mapping hemodynamics remains an open quest in biomedical optical imaging. Although pure optical imaging techniques offer rich optical contrast of blood and have been reported to measure blood […]

Kavli Affiliate: Andrei Faraon | First 5 Authors: Gregory Roberts, Conner Ballew, Tianzhe Zheng, Juan C. Garcia, Sarah Camayd-Muñoz | Summary: Modern imaging systems can be enhanced in efficiency, compactness, and application through introduction of multilayer nanopatterned structures for manipulation of light based on its fundamental properties. High transmission efficiency multispectral imaging is surprisingly elusive […]

Kavli Affiliate: Chiara Daraio | First 5 Authors: Brian L. Kim, Christoper Chong, Setare Hajarolasvadi, Yifan Wang, Chiara Daraio | Summary: The propagation of acoustic and elastic waves in time-varying, spatially homogeneous media can exhibit different phenomena when compared to traditional spatially-varying, temporally-homogeneous media. In the present work, the response of a one-dimensional phononic lattice […]

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Isabel M. Klein, Alex Krotz, Jonathan M. Michelsen, Scott K. Cushing, | Summary: Transient X-ray spectroscopies have become ubiquitous in studying photoexcited dynamics in solar energy materials due to their sensitivity to carrier occupations and local chemical or structural dynamics. The interpretation of solid-state photoexcited dynamics, […]

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Tuvia Gefen, Rajashik Tarafder, Rana X. Adhikari, Yanbei Chen, | Summary: Current laser-interferometric gravitational wave detectors suffer from a fundamental limit to their precision due to the displacement noise of optical elements contributed by various sources. Several schemes for Displacement-Noise Free Interferometers (DFI) have been proposed […]

Kavli Affiliate: Alireza Marandi | First 5 Authors: Ryotatsu Yanagimoto, Rajveer Nehra, Ryan Hamerly, Edwin Ng, Alireza Marandi | Summary: Realization of a room-temperature ultra-fast photon-number-resolving (PNR) quantum nondemolition (QND) measurement would have significant implications for photonic quantum information processing (QIP), enabling, e.g., deterministic quantum computation in discrete-variable architectures, but the requirement for strong coupling […]

Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, , , , | Summary: Let $G=(V(G),E(G))$ be a graph and $d(v)$ be the degree of the vertex $vin V(G)$. The exponential reduced Sombor index of $G$, denoted by $e^{SO_{red}}(G)$, is defined as $$e^{SO_{red}}(G)=sum_{uvin E(G)}e^{sqrt{(d(u)-1)^2+(d(v)-1)^2}}.$$ We obtain a characterization of extremal trees with the maximal […]
