Kavli Affiliate: Morteza Gharib | First 5 Authors: Fengze Xie, Fengze Xie, , , | Summary: Fixed-wing unmanned aerial vehicles (UAVs) offer endurance and efficiency but lack low-speed agility due to highly coupled dynamics. We present an end-to-end sensing-to-control pipeline that combines bio-inspired hardware, physics-informed dynamics learning, and convex control allocation. Measuring airflow on a […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, Zhen Cao, , , | Summary: Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), gamma-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by gamma-ray telescopes, particularly by the Large High Altitude Air Shower Observatory (LHAASO), have revealed a few tens of UHE sources, […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Xiaofeng Dong, Xiaofeng Dong, , , | Summary: The potential of deep learning-based image-to-image translations has recently attracted significant attention. One possible application of such a framework is as a fast, approximate alternative to cosmological simulations, which would be particularly useful in various contexts, including covariance studies, […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Zui Tao, Zui Tao, , , | Summary: We introduce the Wannier function decomposition of excitons (WFDX) method to quantify exciton localization in solids within the ab initio Bethe-Salpeter equation framework. By decomposing each Bloch exciton wavefunction into products of single-particle electron and hole maximally localized […]
Kavli Affiliate: Erin Kara | First 5 Authors: XRISM Collaboration, XRISM Collaboration, , , | Summary: The dynamics of the intra-cluster medium (ICM), the hot plasma that fills galaxy clusters, are shaped by gravity-driven cluster mergers and feedback from supermassive black holes (SMBH) in the cluster cores. XRISM measurements of ICM velocities in several clusters […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Noah E. Wolfe, Noah E. Wolfe, , , | Summary: From catalogs of gravitational-wave transients, the population-level properties of their sources and the formation channels of merging compact binaries can be constrained. However, astrophysical conclusions can be biased by misspecification or misestimation of the population likelihood. Despite […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Sha Azyzy, Sha Azyzy, , , | Summary: Parity-odd four-point correlation functions, or trispectra, of cosmic matter density fields provide a unique probe of fundamental symmetries in cosmology. Trispectra of primordial matter density fluctuations produced in the early universe are modified by the subsequent nonlinear structure formation. […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Julien Fitouchi, Julien Fitouchi, , , | Summary: We investigate the zero-magnetization phase diagram of a spin-1/2 chain with competing ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor exchange couplings in the strongly interacting regime. Using density matrix renormalization group (DMRG) simulations, we discover two successive commensurate-incommensurate transitions of the […]
Kavli Affiliate: Wei Gao | First 5 Authors: Ruyang Liu, Ruyang Liu, , , | Summary: Long-form video understanding has always been a challenging problem due to the significant redundancy in both temporal and spatial contents. This challenge is further exacerbated by the limited context length of Multimodal Large Language Models (MLLMs). To address this […]
Kavli Affiliate: T. Higuchi | First 5 Authors: T. Hepworth, T. Hepworth, , , | Summary: We report the construction and commissioning of a new ultracold neutron (UCN) guide-coating facility at the University of Winnipeg. The facility employs pulsed laser deposition (PLD) to produce diamond-like carbon (DLC) coatings on cylindrical UCN guides up to 1 […]
