Kavli Affiliate: Feng Wang | First 5 Authors: Ziqiang CHen, Ziqiang CHen, , , | Summary: This letter investigates the robust beamforming design for a near-field secure integrated sensing and communication (ISAC) system with multiple communication users (CUs) and targets, as well as multiple eavesdroppers. Taking into account the channel uncertainty constraints, we maximize the […]
Kavli Affiliate: Aaron Roodman | First 5 Authors: Colin Orion Chandler, Colin Orion Chandler, , , | Summary: We report on the observation and measurement of astrometry, photometry, morphology, and activity of the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS), with the NSF-DOE Vera C. Rubin Observatory. The third interstellar object, comet 3I/ATLAS, was […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Hong-Xuan Jiang, Hong-Xuan Jiang, , , | Summary: Sagittarius~A$^*$, the supermassive black hole at the center of our galaxy, exhibits flares across various wavelengths, yet their origins remain elusive. We performed 3D two-temperature General Relativistic Magnetohydrodynamic (GRMHD) simulations of magnetized accretion flows initialized from multi-loop magnetic field […]
Kavli Affiliate: Darrell Schlom | First 5 Authors: Arundhati Ghosal, Arundhati Ghosal, , , | Summary: Conventional racetrack memories move information by pushing magnetic domain walls or other spin textures with spin-polarized currents, but the accompanying Joule heating inflates their energy budget and can hamper scaling. Here we present a voltage-controlled, magnetoelectric racetrack in which […]

Ma | Summary: Visible light influences a range of physiological processes, yet how animals respond to it independently of the visual system remains largely unknown. Here, we uncover a […]
Kavli Affiliate: Joshua Vogelstein | Authors: Tingshan Liu, Jayanta Dey, Beiya Xu, Samuel S Alldritt, Karl-Heinz Nenning, Kyoungseob Byeon, Ting Xu and Joshua T. Vogelstein | Summary: Sex classification using neuroimaging data has the potential to revolutionize personalized diagnostics by revealing subtle structural brain differences that underlie sex-specific disease risks. Despite the promise of machine […]
Kavli Affiliate: Wei Gao | First 5 Authors: Fei Shuang, Fei Shuang, , , | Summary: We investigate the kinetics of phase transition between the 2H and 1T$^prime$ phases in monolayer MoTe$_2$ using atomistic simulations based on a machine learning interatomic potential trained on SCAN-DFT data, combined with mean field kinetic theory to interpret the […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Kriti Kamal Gupta, Kriti Kamal Gupta, , , | Summary: Active galactic nuclei (AGN) emit radiation via accretion across the entire energy spectrum. While the standard disk and corona model can somewhat describe this emission, it fails to predict specific features such as the soft X-ray excess, […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, Belle II Collaboration, , , | Summary: We recently measured the branching fraction of the $B^+rightarrow K^+nubarnu$ decay using 362 fb$^-1$ of on-resonance $e^+e^-$ collision data, under the assumption of Standard Model kinematics, providing the first evidence for this decay. To facilitate future reinterpretations […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Akifumi Chitose, , , | Summary: Cosmic strings are predicted in various extensions of the Standard Model, including grand unified theories. Depending on the symmetry-breaking pattern, they can be either topologically stable or metastable. Intriguingly, metastable strings have been proposed as a possible origin of […]
