Surface acoustic wave resonators on thin film piezoelectric substrates in the quantum regime

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 […]

Engineered zero-dispersion microcombs using CMOS-ready photonics

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 […]

Contribution of protein conformational heterogeneity to NMR lineshapes at cryogenic temperatures

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 […]

Predicted and Experimental NMR Chemical Shifts at Variable Temperatures: The Effect of Protein Conformational Dynamics

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 […]

Zinc Alters the Supramolecular Organization of Nucleic Acid Complexes with Full-Length TIA1

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 […]

Connecting cooperative transport by ants with the physics of active swimmers

Kavli Affiliate: Ariel Amir | First 5 Authors: Tabea Heckenthaler, Tobias Holder, Ariel Amir, Ofer Feinerman, Ehud Fonio | Summary: Some ant species are known as efficient transporters that can cooperatively carry food items which would be too large for a single ant. Previous studies of cooperative transport focused on the role of individual ants […]

Cosmic Web Dissection in Fuzzy Dark Matter Cosmologies

Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Anastasia Fialkov, Nina Sartorio, Philip Mocz, | Summary: On large cosmological scales, anisotropic gravitational collapse is manifest in the dark cosmic web. Its statistical properties are little known for alternative dark matter models such as fuzzy dark matter (FDM). In this work, we assess for […]

NICER/NuSTAR Characterization of 4U 1957+11: A Near Maximally Spinning Black Hole Potentially in the Mass Gap

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Erin Barillier, Victoria Grinberg, David Horn, Michael A. Nowak, Ronald A. Remillard | Summary: 4U 1957+11 is a black hole candidate system that has been in a soft X-ray spectral state since its discovery. We present analyses of recent joint NICER and NuSTAR spectra, which are […]

Common rules underlying optogenetic and behavioral modulation of responses in multi-cell-type V1 circuits

Kavli Affiliate: Kenneth Miller | Authors: Agostina Palmigiano, Francesco Fumarola, Daniel P. Mossing, Nataliya Kraynyukova, Hillel Adesnik and Kenneth Miller | Summary: The visual cortex receives non-sensory inputs containing behavioral and brain state information. Here we propose a parallel between optogenetic and behavioral modulations of activity and characterize their impact on cell-type-specific V1 processing under […]

Reacceleration of Galactic Cosmic Rays Beyond the Knee at the Termination Shock of a Cosmic-Ray-Driven Galactic Wind

Kavli Affiliate: Roger Blandford | First 5 Authors: Payel Mukhopadhyay, Enrico Peretti, Noemie Globus, Paul Simeon, Roger Blandford | Summary: The origin of cosmic rays above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a non-rotating, expanding flux tube with a changing speed […]
