3D Atomic-Scale Metrology of Strain Relaxation and Roughness in Gate-All-Around (GAA) Transistors via Electron Ptychography

Posted by klaurent July 9, 2025July 21, 2025Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Shake Karapetyan, Shake Karapetyan, , , | Summary: To improve transistor density and electronic performance, next-generation semiconductor devices are adopting three-dimensional architectures and feature sizes down to the few-nm regime, which require atomic-scale metrology to identify and resolve performance-limiting fabrication challenges. X-ray methods deliver three-dimensional imaging […]

Open Source Planning & Control System with Language Agents for Autonomous Scientific Discovery

Posted by klaurent July 9, 2025July 21, 2025Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: Licong Xu, Licong Xu, , , | Summary: We present a multi-agent system for automation of scientific research tasks, cmbagent (https://github.com/CMBAgents/cmbagent). The system is formed by about 30 Large Language Model (LLM) agents and implements a Planning & Control strategy to orchestrate the agentic workflow, with no […]

The Unhurried Universe: A Continued Search for Long Term Variability in ASAS-SN

Posted by klaurent July 9, 2025July 21, 2025Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Sydney Petz, Sydney Petz, , , | Summary: We search a sample of 5,685,060 isolated sources in the All Sky Automated Survey for SuperNovae (ASAS-SN) with 14.5<g<15 mag for slowly varying sources with brightness changes larger than ~0.03 mag/year over 10 years. We find 426 slowly-varying systems. […]

4KAgent: Agentic Any Image to 4K Super-Resolution

Posted by klaurent July 9, 2025July 21, 2025Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yushen Zuo, Yushen Zuo, , , | Summary: We present 4KAgent, a unified agentic super-resolution generalist system designed to universally upscale any image to 4K resolution (and even higher, if applied iteratively). Our system can transform images from extremely low resolutions with severe degradations, for example, […]

The Nineteenth Data Release of the Sloan Digital Sky Survey

Posted by klaurent July 9, 2025July 21, 2025Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: SDSS Collaboration, SDSS Collaboration, , , | Summary: Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial objects to constrain the physical processes that […]

Sobolev Versus Homogeneous Sobolev II

Posted by klaurent July 9, 2025July 21, 2025UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Pekka Koskela, Pekka Koskela, , , | Summary: We study the relationship between Sobolev extension domains and homogeneous Sobolev extension domains. Precisely, for a certain range of exponents $p$ and $q$, we construct a $(W^1, p, W^1, q)$-extension domain which is not an $(L^1, p, L^1, q)$-extension […]

Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy

Posted by klaurent July 9, 2025July 21, 2025Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Juna A. Kollmeier, Juna A. Kollmeier, , , | Summary: The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the sky with multi-object spectroscopy (MOS) at telescopes in both hemispheres (the 2.5-m Sloan Foundation […]

The Distribution of Atomic Hydrogen in the Host Galaxies of FRBs

Posted by klaurent July 9, 2025July 21, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Hugh Roxburgh, Hugh Roxburgh, , , | Summary: We probe the atomic hydrogen (HI) emission from the host galaxies of fast radio bursts (FRBs) to investigate the emerging trend of disturbance and asymmetry in the population. Quadrupling the sample size, we detect 13 of 14 new hosts […]

Gap reopening as signature of coupling between Majorana zero modes in Sn-(Bi,Sb)2(Te,S)3-based Josephson trijunctions

Posted by klaurent July 9, 2025July 21, 2025Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Duolin Wang, Duolin Wang, , , | Summary: In the past two decades, enormous efforts have been made to search for possible platforms and schemes to implement topological quantum computation (TQC). In exploring the Fu-Kane scheme of TQC based on Josephson trijunctions constructed on topological insulators, the […]
