Distribution Guidance Network for Weakly Supervised Point Cloud Semantic Segmentation

Kavli Affiliate: Wei Gao | First 5 Authors: Zhiyi Pan, Wei Gao, Shan Liu, Ge Li, | Summary: Despite alleviating the dependence on dense annotations inherent to fully supervised methods, weakly supervised point cloud semantic segmentation suffers from inadequate supervision signals. In response to this challenge, we introduce a novel perspective that imparts auxiliary constraints […]

Mind the kinematics simulation of planet-disk interactions: time evolution and numerical resolution

Kavli Affiliate: Ruobing Dong | First 5 Authors: Kan Chen, Ruobing Dong, , , | Summary: Planet-disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated. To explore this, we conduct 3D hydrodynamic simulations using the code FARGO3D to study […]

Gravitational Particle Production of Scalars: Analytic and Numerical Approaches Including Early Reheating

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Leah Jenks, Edward W. Kolb, Keyer Thyme, , | Summary: Cosmological gravitational particle production (GPP) is a generic mechanism by which particles are produced during the inflationary epoch. In this work we consider the GPP of massive scalars in an effort to fully understand the spectrum […]

Where has all the $r$-process gone? Timescales for GRB-Kilonovae to Enrich their Host Galaxies

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Anya E. Nugent, Alexander P. Ji, Wen-fai Fong, Hilay Shah, Freeke van de Voort | Summary: Neutron star (NS) mergers are currently the only observed source of $r$-process production in the Universe. Yet, it is unclear how much $r$-process mass from these mergers is incorporated into […]
