A search for persistent radio sources toward repeating fast radio bursts discovered by CHIME/FRB

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adaeze L. Ibik, Maria R. Drout, Bryan M. Gaensler, Paul Scholz, Navin Sridhar | Summary: The identification of persistent radio sources (PRSs) coincident with two repeating fast radio bursts (FRBs) supports FRB theories requiring a compact central engine. However, deep non-detections in other cases highlight the […]

Improved Halo Model Calibrations for Mixed Dark Matter Models of Ultralight Axions

Kavli Affiliate: George Efstathiou | Summary:We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axion fractions $f leq 0.3$ within the fuzzy dark matter (FDM) window $10^-25$ eV $lesssim m lesssim 10^-23$ eV. Our simulations, using […]

Machine-learning convergent melanocytic morphology despite noisy archival slides

Kavli Affiliate: Michael Keiser | Authors: Mikio Tada, Garrett Gaskins, Sina Ghandian, Nicholas Mew, Michael J. Keiser and Elizabeth S. Keiser | Summary: Melanocytic atypia, ranging from benign to malignant, often leads to diagnostic discordance, complicating its prediction by machine learning models. To overcome this, we paired H&E-stained histology images with contiguous or serial sections […]

Thermo-mechanical Properties of Hierarchical Biocomposite Materials from Photosynthetic Microorganisms

Kavli Affiliate: Chiara Daraio | Summary:Extrusion 3D-printing of biopolymers and natural fiber-based biocomposites allows for the fabrication of complex structures, ranging from gels for healthcare applications to eco-friendly structural materials. However, traditional polymer extrusion demands high-energy consumption to pre-heat the slurries and reduce material viscosity. Additionally, natural fiber reinforcement often requires harsh treatments to improve […]

Topological K-theory of quasi-BPS categories for Higgs bundles

Kavli Affiliate: Yukinobu Toda | Summary:In a previous paper, we introduced quasi-BPS categories for moduli stacks of semistable Higgs bundles. Under a certain condition on the rank, Euler characteristic, and weight, the quasi-BPS categories (called BPS in this case) are non-commutative analogues of Hitchin integrable systems. We proposed a conjectural equivalence between BPS categories which […]
