Kavli Affiliate: Wei Gao | First 5 Authors: Fan Xu, Wuyang Chen, Wei Gao, , | Summary: Decision trees and forests have achieved successes in various real applications, most working with all testing classes known in training data. In this work, we focus on learning with augmented class via forests, where an augmented class may […]
Kavli Affiliate: Joseph Falson | First 5 Authors: Reiley Dorrian, Jinwoong Kim, Adrian Llanos, Veronica Show, Mizuki Ohno | Summary: Deterministic control of the layering configuration of two-dimensional quantum materials plays a central role in studying their emergent electronic properties. Here we demonstrate in-situ control over competing stacking configurations in thin film crystals of the […]
Kavli Affiliate: Michael L. Roukes | First 5 Authors: Andrew N. Cleland, Michael L. Roukes, , , | Summary: We describe a method with which to fabricate sub-micron mechanical structures from silicon-on-insulator substrates. We believe this is the first reported method for such fabrication, and our technique allows for complex, multilayer electron beam lithography to […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Prachi Thureja, Andrew W. Nyholm, Martin Thomaschewski, Phillip R. Jahelka, Julie Belleville | Summary: We report a scalable approach for fabricating single-crystal barium titanate (BTO) thin films through spalling from bulk substrates. Conventional thin film growth techniques often face challenges in achieving high-quality single crystal microstructure […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Scott A. Bollt, Samuel H. Foxman, Morteza Gharib, , | Summary: We present a novel architecture for accelerating PIV calculations. An optical flow hardware accelerator does the brunt of the work, with cross-correlation only providing quick corrections. The result is RapidPIV: a free-to-download software program for real-time […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Jinhao Ge, Peng Liu, Bohan Li, Mingxiao Li | Summary: Achieving compact and efficient visible laser sources is crucial for a wide range of applications. However traditional semiconductor laser technology faces difficulties in producing high-brightness green light, leaving a green gap in wavelength coverage. Second-harmonic […]
Kavli Affiliate: Changhuei Yang | First 5 Authors: Zhenyu Dong, Haowen Zhou, Ruizhi Cao, Oumeng Zhang, Shi Zhao | Summary: Three-dimensional (3D) refractive index (RI) tomography offers label-free, quantitative volumetric imaging but faces limitations due to optical aberrations, limited resolution, and the computational complexity inherent to existing approaches. To overcome these barriers, we propose Analytic […]
Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yang Zhang, Shuai Na, Jonathan J. Russin, Karteekeya Sastry, Li Lin | Summary: Imaging the human body’s morphological and angiographic information is essential for diagnosing, monitoring, and treating medical conditions. Ultrasonography performs the morphological assessment of the soft tissue based on acoustic impedance variations, whereas photoacoustic […]
Kavli Affiliate: Wei Gao | First 5 Authors: Haoming Wang, Boyuan Yang, Xiangyu Yin, Wei Gao, | Summary: Personalization of Large Language Models (LLMs) is important in practical applications to accommodate the individual needs of different mobile users. Due to data privacy concerns, LLM personalization often needs to be locally done at the user’s mobile […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Alexey Tiranov, Emanuel Green, Sophie Hermans, Erin Liu, Federico Chiossi | Summary: Optically addressable solid-state spins have been extensively studied for quantum technologies, offering unique advantages for quantum computing, communication, and sensing. Advancing these applications is generally limited by finding materials that simultaneously provide lifetime-limited optical and […]
