Kavli Affiliate: Herre Van Der Zant | First 5 Authors: Jan N. Kirchhof, Yuefeng Yu, Denis Yagodkin, Nele Stetzuhn, Daniel B. de Araújo | Summary: Nanomechanical spectroscopy (NMS) is a recently developed approach to determine optical absorption spectra of nanoscale materials via mechanical measurements. It is based on measuring changes in the resonance frequency of […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Kate Napier, Keren Sharon, Håkon Dahle, Matthew Bayliss, Michael D. Gladders | Summary: Tension between cosmic microwave background-based and distance ladder-based determinations of the Hubble constant ${rm H}_{rm 0}$ motivates pursuit of independent methods that are not subject to the same systematic effects. A promising alternative, […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Thomas Luschmann, Alexander Jung, Stephan Geprägs, Franz X. Haslbeck, Achim Marx | Summary: Lithium niobate (LNO) is a well established material for surface acoustic wave (SAW) devices including resonators, delay lines and filters. Recently, multi-layer substrates based on LNO thin films have become commercially available. Here, we […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Maodong Gao, Yan Yu, Heming Wang, Warren Jin | Summary: Soliton microcombs are helping to advance the miniaturization of a range of comb systems. These combs mode lock through the formation of short temporal pulses in anomalous dispersion resonators. Here, a new microcomb is demonstrated […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Qing-Xin Ji, Warren Jin, Lue Wu, Yan Yu, Zhiquan Yuan | Summary: Normal group velocity dispersion (GVD) microcombs offer high comb line power and high pumping efficiency compared to bright pulse microcombs. The recent demonstration of normal GVD microcombs using CMOS-foundry-produced microresonators is an important step towards […]
Kavli Affiliate: Ann McDermott | Authors: Xu Yi, Keith Fritzsching, Rivkah Rogawski, Yunyao Xu and Ann E McDermott | Summary: While low temperature NMR holds great promise for the analysis of unstable samples and for sensitizing NMR detection, spectral broadening in frozen protein samples is a common experimental challenge. One hypothesis explaining the additional linewidth […]
Kavli Affiliate: Ann McDermott | Authors: Xu Yi, Lichirui Zhang, Richard Friesner and Ann E McDermott | Summary: NMR chemical shifts provide a sensitive probe of protein structure and dynamics. Prediction of shifts, and therefore interpretation of shifts, particularly for the frequently measured amidic 15N sites, remains a tall challenge. We demonstrate that protein 15N […]
Kavli Affiliate: Ann McDermott | Authors: Yizhuo Yang, Keith Fritzsching, Sasha He and Ann E McDermott | Summary: T-Cell Intracellular Antigen-1 (TIA1) is a 43 kDa multi-domain RNA-binding protein involved in stress granule formation during eukaryotic stress response, and has been implicated in neurodegenerative diseases including Welander distal myopathy and amyotrophic lateral sclerosis. TIA1 contains […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Benjamin J. Ricketts, James F. Steiner, Cecilia Garraffo, Ronald A. Remillard, Daniela Huppenkothen | Summary: Black hole X-ray binary systems (BHBs) contain a close companion star accreting onto a stellar-mass black hole. A typical BHB undergoes transient outbursts during which it exhibits a sequence of long-lived […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Andrei Faraon, , | Summary: The ideal imaging system would efficiently capture information about all fundamental properties light: intensity, direction, wavelength, and polarization. Most common imaging systems only map the spatial degrees of freedom of light onto a two dimensional image sensor, with […]
