Kavli Affiliate: George Efstathiou | Summary:Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio Surveyor would open this largely-unexplored region of the electromagnetic spectrum with a space-based interferometer to (1)~Track the space weather of other stars; (2)~Detect magnetically-generated emission from exoplanets […]
Kavli Affiliate: David W. Miller | Summary:I propose a simple and progressive way of designing and fabricating complex multilayered optics, even as we scale to large numbers of layers. The approach relies on successive layers of two-by-two blocks in which light only flows in the forward direction. It exploits a proposed trapezoidal architecture that can […]

Kavli Affiliate: Gordan Krnjaic | Summary:IceCube has recently detected a diffuse population of high-energy neutrinos arising from the Milky Way. We use this high-significance detection to place new limits on dark matter (DM) annihilation to neutrinos with two complementary approaches. The first method uses the background-subtracted Galactic longitude distribution of shower events to place a […]
Kavli Affiliate: Taizan Watari | Summary:In this note, we describe the Gepner construction purely as orbifold (rather than a beta-prescription or orbifold-like process). This is done by distinguishing orbifolding by a chiral symmetry from that by a left-right diagonal symmetry, and also by exploiting an extra degree of freedom available in orbifolds of Type 0 […]
Kavli Affiliate: Giordano Scappucci | Summary:Strained germanium ($varepsilon$-Ge) quantum wells on metamorphic SiGe buffers have enabled advanced hole-based spin qubit devices. Alternatively, unstrained Ge with lattice-matched strained silicon-germanium ($varepsilon$-SiGe) barriers eliminates the need for metamorphic buffers altogether. The ground state character of both these platforms is predominantly heavy-hole (HH) with a largely anisotropic spin response. […]
Kavli Affiliate: Wei Gao| Summary:The existing methods for saliency detection task focus on the application of multi-level features, aiming to take advantage of the respective strengths of high- and low-level features. However, because the inputs of these models are single-size images, their multi-level features have difficulty in learning the knowledge of size variations of salient […]
Kavli Affiliate: Luis Ho | Summary:We use high-resolution hydrodynamic simulations in the MACER framework to explain why low-redshift PG quasar hosts can retain substantial cold-gas reservoirs, with gas fractions and gas-to-stellar mass ratios showing little dependence on instantaneous AGN luminosity. This paper is the third in a series systematically studying AGN feedback in a disk […]
Kavli Affiliate: Li Zhao | Authors: Zhao Li, Aaron James and Shengxuan Li | Summary: Background Reference catalogs such as GENCODE capture most stably expressed mammalian genes but may not include condition-restricted or low-abundance transcripts. Reads supporting unannotated intergenic splice junctions are generally absent from annotation-restricted gene-count matrices; transcript assemblers may reconstruct a subset as novel […]
Kavli Affiliate: A. James Hudspeth | Authors: Swarna Jeewajee, Francesco Gianoli, Maria Jussila, Brian Ciruna, Aaron Steiner, Adrian Jacobo and Albert James Hudspeth | Summary: The conserved core planar cell polarity (PCP) pathway orients cells and subcellular structures within an epithelium through asymmetric protein localization and intercellular communication(1–4). In vestibular organs and lateral-line neuromasts, mechanosensory […]
