Kavli Affiliate: Ke Wang | First 5 Authors: Aojun Zhou, Ke Wang, Zimu Lu, Weikang Shi, Sichun Luo | Summary: Recent progress in large language models (LLMs) like GPT-4 and PaLM-2 has brought significant advancements in addressing math reasoning problems. In particular, OpenAI’s latest version of GPT-4, known as GPT-4 Code Interpreter, shows remarkable performance […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Zhengli Wang, Jiguang Lu, Jinchen Jiang, Shunshun Cao, Kejia Lee | Summary: We observed the nearby 100$%$-duty-cycle radio pulsar B0950+08 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We obtained the polarization profile for its entire rotation, which enabled us to investigate its magnetospheric radiation geometry and […]

Kavli Affiliate: Jing Wang | First 5 Authors: Zhenyu Ni, Jing Wang, Liying Kang, , | Summary: For a simple graph $F$, let $mathrm{EX}(n, F)$ and $mathrm{EX_{sp}}(n,F)$ be the set of graphs with the maximum number of edges and the set of graphs with the maximum spectral radius in an $n$-vertex graph without any copy […]
Kavli Affiliate: Roger Blandford | First 5 Authors: Noémie Globus, Anatoli Fedynitch, Roger Blandford, , | Summary: Extreme Energy Cosmic Rays, EECRs — cosmic rays with energies beyond the GZK cutoff (i.e. greater than 100 EeV) are scarce. Only a few of such events have been detected by air shower experiments and the nature of […]
