Key details

• To address these challenges, we introduce a novel multi-center benchmark for multi-organ abdominal disease diagnosis and automated radiology report generation, which learns to synthesize contrast-enhanced findings from single-phase non-contrast CT (NCCT).
• To support this, we curated a large-scale dataset of paired NCCT-CECT studies and their corresponding contrast-enhanced radiology reports from two centers, partitioned into internal sets and an external validation cohort.
• Under a unified evaluation protocol, we benchmarked five contemporary deep learning architectures encompassing chest-specific, abdomen-specific, and general-purpose multimodal domains.
• Extensive experiments demonstrate that NCCT retains diagnostic signals, achieving an average multi-organ AUC of 69.1% on the internal cohort and 63.1% on the external cohort, respectively.

• To address these challenges, we propose AlignCoder, a repository-level code completion framework that introduces a query enhancement mechanism and a reinforcement learning based retriever training method.

• Additionally, we employ reinforcement learning to train an AlignRetriever that learns to leverage inference information in the enhanced query for more accurate retrieval.

Key details

• Regressions occasionally slipped through.
• Sometimes changes made it all the way to production only to be reverted later.

  We tried several AI code review tools, but most operate at PR time.

• I wanted review to happen while the implementation was still fresh in the developer's mind at a team level (soft enforcement).
• I also wanted to emphasize responsibility for keeping prod stable with each individual engineer.

  So I built git-lrc.

  When you commit, git-lrc opens a review UI with your diff.

Results & evidence

• It summarizes what changed, points out things that deserve a second look, and lets you quickly jump through the important parts of the change.

  Over time, git-lrc has grown to check for around 100 common risk patterns across 10 categories, including securi...

• It's a quick 60 seconds spent looking at your own work before it gets recorded in git.

  It also generates a short "summary deck" that highlights the main changes, with special emphasis on potential risks.

arXiv:2606.15037v1 Announce Type: new Abstract: Radiology report evaluation is essential for advancing automated report generation.

Key details

• Natural language generation metrics have limited clinical relevance.
• Clinical efficacy (CE) metrics evaluate important medical findings, but focus mainly on presence and cover only a limited set of entities.
• Due to heavy reliance on manual annotations, it is difficult for CE metrics to extend clinical entities or attributes.
• In clinical practice, radiology reports serve as a medium for information transfer.

Key details

• Our contribution is a reproducible recipe for training a supervised classifier from routinely collected cancer registry data.
• It describes how to build the in-domain training set and a production-matched holdout, and to choose operating points that keep the false-negative rate (FNR) very low while keeping reviewer workload manageable.
• The pipeline standardizes data curation with facility-stratified sampling and separate handling of reports linked to registry cases, and includes a blinded manual audit to estimate positive-case prevalence and label noise.
• On a 418k-report holdout set, the Kentucky model achieved FNR 0.003 and false-positive rate (FPR) 0.097, improving over the Seattle-trained MOSSAIC OncoID baseline (FNR 0.010, FPR 0.183) and raising F1 from 0.860 to 0.922.
