The R-Process Alliance: Exploring the cosmic scatter among ten r-process sites with stellar abundances

Posted by klaurent October 29, 2025MIT

Kavli Affiliate: Anna Frebel | Summary:The astrophysical origin of the rapid neutron-capture process (r-process), which produces about half of the elements heavier than iron, remains uncertain. The oldest, most metal-poor stars preserve the chemical signatures of early nucleosynthesis events and can reveal the nature of the r-process sites. We present a homogeneous chemical abundance analysis […]

Platform Architecture for Tight Coupling of High-Performance Computing with Quantum Processors

Posted by klaurent October 29, 2025Berkeley

Kavli Affiliate: Irfan Siddiqi | Summary:We propose an architecture, called NVQLink, for connecting high-performance computing (HPC) resources to the control system of a quantum processing unit (QPU) to accelerate workloads necessary to the operation of the QPU. We aim to support every physical modality of QPU and every type of QPU system controller (QSC). The […]

Contactless cavity sensing of superfluid stiffness in atomically thin 4Hb-TaS$_2$

Posted by klaurent October 29, 2025Berkeley

Kavli Affiliate: Irfan Siddiqi | Summary:The exceptional tunability of two-dimensional van der Waals materials offers unique opportunities for exploring novel superconducting phases. However, in such systems, the measurement of superfluid phase stiffness, a fundamental property of a superconductor, is challenging because of the mesoscopic sample size. Here, we introduce a contact-free technique for probing the […]

NanoVLA: Routing Decoupled Vision-Language Understanding for Nano-sized Generalist Robotic Policies

Posted by klaurent October 29, 2025November 10, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jiahong Chen, Jiahong Chen, , , | Summary: Vision-language-action (VLA) models have significantly advanced robotic manipulation by integrating vision-language models (VLMs), and action decoders into a unified architecture. However, their deployment on resource-constrained edge devices, such as mobile robots or embedded systems (e.g., Jetson Orin Nano), remains […]

Trichome entanglement enhances damage tolerance in microstructured biocomposites

Posted by klaurent October 28, 2025Caltech

Kavli Affiliate: Chiara Daraio | Summary:Achieving damage tolerance in composite materials remains a central challenge in materials science. Conventional strategies often rely on filler incorporation or chemical modification, which can limit energy dissipation and constrain structural stability. Here, we leverage the unique morphology of Spirulina trichomes to investigate a reinforcement mechanism based on physical filament […]

The White Dwarf Initial-Final Mass Relation from Open Clusters in Gaia DR3

Posted by klaurent October 28, 2025Chicago

Kavli Affiliate: David W. Miller | Summary:The initial-final mass relation (IFMR) links a star’s birth mass to the mass of its white dwarf (WD) remnant, providing key constraints on stellar evolution. Open clusters offer the most straightforward way to empirically determine the IFMR, as their well-defined ages allow for direct progenitor lifetime estimates. We construct […]
