Higher Order Nyquist Zone Sampling with RFSoC Data Converters for Astronomical and High Energy Physics Readout Systems

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao Liu, Zeeshan Ahmed, Shawn W. Henderson, Ryan Herbst, Larry Ruckman | Summary: From generation to generation, the maximum RF frequency and sampling rate of the integrated data converters in RF system-on-chip (RFSoC) family devices from Xilinx increases significantly. With the integrated digital mixers and up and […]

Machine assisted annotation in neuroanatomy

Posted by klaurent UCSD / Salk

Kavli Affiliate: David Kleinfeld | Authors: Kui Qian, David Kleinfeld, Beth Friedman and Yoav Freund | Summary: One routine and necessary, yet time-consuming task in neuroanatomy is the annotation of labeled cells relative to the background. Currently, staining and imaging techniques enable the marking of specific cell groups with fluorescent dyes. Modern high throughput scanning […]

All-dielectric high-Q dynamically tunable transmissive metasurfaces

Posted by klaurent Caltech

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Ruzan Sokhoyan, Claudio U. Hail, Morgan Foley, Meir Y. Grajower, Harry A. Atwater | Summary: Active metasurfaces, which are arrays of actively tunable resonant elements, can dynamically control the wavefront of the scattered light at a subwavelength scale. To date, most active metasurfaces that enable dynamic […]

Gravitational Wave Measurement in the Mid-Band with Atom Interferometers

Posted by dbos Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Sebastian Baum, Zachary Bogorad, Peter W. Graham, , | Summary: Gravitational Waves (GWs) have been detected in the $sim$100 Hz and nHz bands, but most of the gravitational spectrum remains unobserved. A variety of detector concepts have been proposed to expand the range of observable frequencies. […]

Particle-hole asymmetric ferromagnetism and spin textures in the triangular Hubbard-Hofstadter model

Posted by dbos UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Jixun K. Ding, Luhang Yang, Wen O. Wang, Ziyan Zhu, Cheng Peng | Summary: In a lattice model subject to a perpendicular magnetic field, when the lattice constant is comparable to the magnetic length, one enters the "Hofstadter regime," where continuum Landau levels become fractal magnetic Bloch […]

Lysosomal TMEM106B interacts with galactosylceramidase to regulate myelin lipid metabolism

Posted by klaurent Yale

Kavli Affiliate: Stephen Strittmatter | Authors: Hideyuki Takahashi, Azucena Perez-Canamas, Hongping Ye, Xianlin Han and Stephen M. Strittmatter | Summary: TMEM106B is an endolysosomal transmembrane protein not only associated with multiple neurological disorders including frontotemporal dementia, Alzheimer’s disease, and hypomyelinating leukodystrophy but also potentially involved in COVID-19. Additionally, recent studies have identified amyloid fibrils of […]
