Breaking the Chain: A Causal Analysis of LLM Faithfulness to Intermediate Structures
Announce Type: replace Abstract: In schema-guided reasoning (SGR) pipelines, LLMs produce explicit intermediate structures -- rubrics, checklists, or verification queries -- before committing to a final decision. SGR is increasingly adopted because it promises controllability: practitioners expect to inspect, edit, and override these structures to steer the outcome.
Scientists find wind blowing from our Milky Way's black hole after half-century search: 'There it is'
Scientists find wind blowing from our Milky Way's black hole after half-century search: 'There it is' "There is the thing that everybody’s been looking for for 50 years." After searching for 50 years, astronomers have finally discovered evidence of powerful winds blowing from Sagittarius A* (Sgr A*), the supermassive black hole at the heart of our galaxy. The discovery represents a deepening of our understanding of the physics at play both around supermassive black holes and at the heart of...
Milky Way black hole's missing wind finally found after a half-century-long search
Milky Way black hole's missing wind finally found after a half-century-long search Sadie Harley Scientific Editor Robert Egan Associate Editor After more than 50 years of searching, astrophysicists at Northwestern University have finally discovered evidence of a powerful wind blowing from the Milky Way's central supermassive black hole, Sagittarius A* (Sgr A*). According to theoretical physics and a long-accepted understanding of galaxies' evolution, as black holes consume materials, they...
Stepwise Reasoning Enhancement for LLMs via External Subgraph Generation
Announce Type: new Abstract: Large language models have shown strong performance in natural language generation and downstream reasoning tasks, but they still struggle with logical consistency, factual grounding, and interpretability in complex multi-step reasoning. To address these limitations, this paper proposes SGR, a stepwise reasoning enhancement framework that integrates large language models with external knowledge graphs through query-relevant subgraph generation. Given an input...
Wind from Milky Way's supermassive black hole is finally discovered
Wind from Milky Way's supermassive black hole is finally discovered WASHINGTON, June 5 : After five decades of trying, astronomers have finally discovered the wind emanating from the supermassive black hole at the center of our Milky Way galaxy, though it turns out it is more of a gentle breeze than a hurricane. Using data from the Chile-based ALMA telescope and NASA's orbiting Chandra X-ray Observatory, the researchers viewed the cosmic neighborhood around the black hole - called...
James Webb Space Telescope weighs 'sleeping giant' black hole from 10 billion light-years away — and it's 6 billion times our sun's mass
James Webb Space Telescope weighs 'sleeping giant' black hole from 10 billion light-years away — and it's 6 billion times our sun's mass "We can now undertake a more complete census of how black holes develop over time and infer their role in shaping galaxy evolution." Using the James Webb Space Telescope (JWST), astronomers have "weighed" a sleeping giant — a dormant supermassive black hole located a staggering 10 billion light-years away. That makes this black hole the most distant...
SIRT7 regulates dosage compensation and safeguards the female X chromosome
Abstract Sirtuins are deacetylases implicated in stress responses and longevity in mammals1,2. Although their differential impact on disease for the two sexes has been noted3,4,5,6,7, the underlying reasons are unclear. Here, using Sirt7 as a model in mice, we examine the mechanisms leading to sex differences and find that Sirt7−/− female mice have decreased fitness throughout their lifespan.
There's no escaping it: an exploration of ANSI codes
There's no escaping it: an exploration of ANSI codes ANSI escape codes are kinda crazy, no? I mean, crazy in the sense that they are such a simple and enduring concept. Every time your terminal renders bold red text or a progress bar crawls across the screen, you’re taking advantage of a standard that is almost 50 years old.
