Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Shunsaku Nagasawa, Shunsaku Nagasawa, , , | Summary: We have developed a wide-gap CdTe double-sided strip detector (CdTe-DSD) for the fourth and fifth flights of the Focusing Optics X-ray Solar Imager sounding rocket experiment (FOXSI-4/FOXSI-5). This detector features a 30 um strip width and a variable gap […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Shunsaku Nagasawa, Shunsaku Nagasawa, , , | Summary: The energy range from a few hundred keV to a few MeV includes important probes such as nuclear gamma-rays and the 511 keV annihilation line. However, compared to X-rays and GeV/TeV gamma-rays, this range suffers from lower sensitivity by […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Xinbo Zhang, Xinbo Zhang, , , | Summary: Driving behavior big data leverages multi-sensor telematics to understand how people drive and powers applications such as risk evaluation, insurance pricing, and targeted intervention. Usage-based insurance (UBI) built on these data has become mainstream. Telematics-captured near-miss events (NMEs) […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Yuting Tan, Yuting Tan, , , | Summary: Gradient-based adversarial prompting, such as the Greedy Coordinate Gradient (GCG) algorithm, has emerged as a powerful method for jailbreaking large language models (LLMs). In this paper, we present a systematic appraisal of GCG and its annealing-augmented variant, T-GCG, across […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Jiayu Shang, Jiayu Shang, , , | Summary: Accurate prediction of virus-host interactions is critical for understanding viral ecology and developing applications like phage therapy. However, the growing number of computational tools has created a complex landscape, making direct performance comparison challenging due to inconsistent benchmarks and […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Ignas Juodžbalis, Ignas Juodžbalis, , , | Summary: Recent discoveries of faint active galactic nuclei (AGN) at the redshift frontier have revealed a plethora of broad Halpha emitters with optically red continua, named Little Red Dots (LRDs), which comprise 15-30% of the high redshift broad line AGN […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhijie Zhang, Zhijie Zhang, , , | Summary: Current galaxy formation models predict the existence of X-ray-emitting gaseous halos around Milky Way (MW)-type galaxies. To investigate properties of this coronal gas in MW-like galaxies, we analyze a suite of high-resolution simulations based on the it SMUGGLE framework, […]
Kavli Affiliate: Sara Seager | First 5 Authors: Carina M. Persson, Carina M. Persson, , , | Summary: We present the detection and characterisation of the TOI-1438 multi-planet system discovered by TESS. We collected a series of follow-up observations including high-spectral resolution observations with HARPS-N over a period of five years. Our modelling shows that […]
Kavli Affiliate: Long Zhang | First 5 Authors: Long Zhang, Long Zhang, , , | Summary: The depletion of energy sources, worsening environmental issues, and the quantum limitations of integrated circuits for information storage in the post-Moore era, are pressing global concerns. Fortunately, two-dimensional (2D) Janus materials, possessing broken spatial symmetry, with emerging pressure-dependent and […]
