NICER Discovery of the Accreting Millisecond X-ray Pulsar SRGA J144459.2-604207

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Mason Ng, Paul S. Ray, Andrea Sanna, Tod E. Strohmayer, Alessandro Papitto | Summary: We present the discovery, with the Neutron Star Interior Composition Explorer (NICER), of the 447.9 Hz accreting millisecond X-ray pulsar (AMXP) SRGA J144459.2-604207, which underwent a four-week long outburst starting on 2024 February […]

KAN: Kolmogorov-Arnold Networks

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Yixuan Wang, Sachin Vaidya, Fabian Ruehle, James Halverson | Summary: Inspired by the Kolmogorov-Arnold representation theorem, we propose Kolmogorov-Arnold Networks (KANs) as promising alternatives to Multi-Layer Perceptrons (MLPs). While MLPs have fixed activation functions on nodes ("neurons"), KANs have learnable activation functions on edges ("weights"). […]

The Nature of X-Rays from Young Stellar Objects in the Orion Nebula Cluster — A Chandra HETGS Legacy Project

Kavli Affiliate: David A. Principe | First 5 Authors: Norbert S. Schulz, David P. Huenemoerder, David A. Principe, Marc Gagne, Hans Moritz Günther | Summary: The Orion Nebula Cluster (ONC) is the closest site of very young ($sim$ 1 Myrs) massive star formation. The ONC hosts more than 1600 young and X-ray bright stars with […]

AoI-aware Sensing Scheduling and Trajectory Optimization for Multi-UAV-assisted Wireless Backscatter Networks

Kavli Affiliate: Bo Gu | First 5 Authors: Yusi Long, Songhan Zhao, Shimin Gong, Bo Gu, Dusit Niyato | Summary: This paper considers multiple unmanned aerial vehicles (UAVs) to assist sensing data transmissions from the ground users (GUs) to a remote base station (BS). Each UAV collects sensing data from the GUs and then forwards […]

Small Instanton Effects on Composite Axion Mass

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Takafumi Aoki, Masahiro Ibe, Satoshi Shirai, Keiichi Watanabe, | Summary: This paper investigates the impact of small instanton effects on the axion mass in the composite accidental axion (CAA) models. These models are designed to address the axion quality problem, where QCD gauge symmetry is embedded as […]

Dynamical Responses Predict a Distal Site that Modulates Activity in an Antibiotic Resistance Enzyme

Kavli Affiliate: Michael Beer | Authors: Michael Beer, Ana Sofia F. Oliveira, Catherine L. Tooke, Philip Hinchliffe, Angie Tsz Yan Li, Balazs Balega, James Spencer and Adrian J Mulholland | Summary: β-Lactamases, which hydrolyse β-lactam antibiotics, are key determinants of antibiotic resistance. Predicting the sites and effects of distal mutations in enzymes is challenging. For […]

Comparative Single Cell Analysis of Transcriptional Bursting Reveals the Role of Genome Organization on de novo Transcript Origination

Kavli Affiliate: Li Zhao | Authors: UnJin Lee, Cong Li, Christopher B Langer, Nicolas Svetec and Li Zhao | Summary: Spermatogenesis is a key developmental process underlying the origination of newly evolved genes. However, rapid cell type-specific transcriptomic divergence of the Drosophila germline has posed a significant technical barrier for comparative single-cell RNA-sequencing (scRNA-Seq) studies. […]

Planet Hunters TESS V: a planetary system around a binary star, including a mini-Neptune in the habitable zone

Kavli Affiliate: Sara Seager | First 5 Authors: Nora L. Eisner, Samuel K. Grunblatt, Oscar Barragán, Thea H. Faridani, Chris Lintott | Summary: We report on the discovery and validation of a transiting long-period mini-Neptune orbiting a bright (V = 9.0 mag) G dwarf (TOI 4633; R = 1.05 RSun, M = 1.10 MSun). The […]

Colloidal dispersions of sterically and electrostatically stabilized PbS quantum dots: the effect of stabilization mechanism on structure factors, second virial coefficients, and film-forming properties

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Ahhyun Jeong, Josh Portner, Christian P. N. Tanner, Justin C. Ondry, Chenkun Zhou | Summary: Electrostatically stabilized nanocrystals (NCs) and, in particular, quantum dots (QDs) hold promise for forming strongly coupled superlattices due to their compact and electronically conductive surface ligands. However, studies on the colloidal […]
