Kavli Affiliate: Alyosha Molnar | First 5 Authors: Oscar Castañeda, Zachariah Boynton, Seyed Hadi Mirfarshbafan, Shimin Huang, Jamie C. Ye | Summary: All-digital millimeter-wave (mmWave) massive multi-user multiple-input multiple-output (MU-MIMO) receivers enable extreme data rates but require high power consumption. In order to reduce power consumption, this paper presents the first resolution-adaptive all-digital receiver ASIC […]

Kavli Affiliate: Alyosha Molnar | First 5 Authors: Oscar Castañeda, Seyed Hadi Mirfarshbafan, Shahaboddin Ghajari, Alyosha Molnar, Sven Jacobsson | Summary: All-digital basestation (BS) architectures for millimeter-wave (mmWave) massive multi-user multiple-input multiple-output (MU-MIMO), which equip each radio-frequency chain with dedicated data converters, have advantages in spectral efficiency, flexibility, and baseband-processing simplicity over hybrid analog-digital solutions. […]

Kavli Affiliate: Grace Xing | First 5 Authors: Reet Chaudhuri, Zhen Chen, David Muller, Huili Grace Xing, Debdeep Jena | Summary: High-conductivity undoped GaN/AlN 2D hole gases (2DHGs), the p-type dual of the AlGaN/GaN 2D electron gases (2DEGs), have offered valuable insights into hole transport in GaN and enabled the first GaN GHz RF p-channel […]

Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Mikel Gómez Ruiz, Kevin Lee, Henryk Turski, Shyam Bharadwaj | Summary: This report classifies emission inhomogeneities that manifest in InGaN quantum well blue light-emitting diodes grown by plasma-assisted molecular beam epitaxy on free-standing GaN substrates. By a combination of spatially resolved electroluminescence and cathodoluminescence […]

Kavli Affiliate: Itai Cohen | First 5 Authors: Thomas Wyse Jackson, Jonathan Michel, Pancy Lwin, Lisa A. Fortier, Moumita Das | Summary: Healthy cartilage is a remarkable tissue, able to withstand tens of millions of loading cycles with minimal damage. While much is known about the structural origins of its compressive mechanics, how composition determines […]

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Motoki Osada, Bai Yang Wang, Berit H. Goodge, Shannon P. Harvey, Kyuho Lee | Summary: The observation of superconductivity in infinite layer nickelate (Nd,Sr)NiO$_{2}$ thin films has led to rapid theoretical and experimental investigations of these copper-oxide-analogue systems [1-15]. Superconductivity has also been found in (Pr,Sr)NiO$_{2}$ […]

Kavli Affiliate: Chris Xu | First 5 Authors: Alan Q. Wang, Aaron K. LaViolette, Leo Moon, Chris Xu, Mert R. Sabuncu | Summary: Compressed sensing fluorescence microscopy (CS-FM) proposes a scheme whereby less measurements are collected during sensing and reconstruction is performed to recover the image. Much work has gone into optimizing the sensing and […]

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Ethan T. Ritz, Nicole A. Benedek, , , | Summary: The thermal properties of materials are critically important to various technologies and are increasingly the target of materials design efforts. However, it is only relatively recent advances in first-principles computational techniques that have enabled researchers to […]

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Kevin S. Olsson, Jeongheon Choe, Martin Rodriguez-Vega, Guru Khalsa, Nicole A. Benedek | Summary: Spin-phonon interaction is an important channel for spin and energy relaxation in magnetic insulators. Understanding this interaction is critical for developing magnetic insulator-based spintronic devices. Quantifying this interaction in yttrium iron garnet […]
