Analog-DB: An Agent-First Analog Integrated Circuit Database, From Blocks to Systems

A shareable library that lets AI design analog circuits from reusable pieces

Researchers created an open-source database that stores analog circuit designs in a format that can be shared freely, retargeted to different manufacturing processes, and automatically discovered by AI agents. When tested on voltage regulators, AI using the database caught design flaws—including missing circuit components—that a conventional sizing-only approach missed, and fixed failing circuits in one to three iterations.

Analog circuit design currently requires extensive trial-and-error and knowledge locked behind non-disclosure agreements, slowing innovation and limiting who can participate. This database removes those barriers by making proven designs reusable and machine-readable, enabling AI tools to find and adapt existing solutions automatically. For companies and researchers, that means faster design cycles and fewer errors; for the field, it means knowledge can accumulate and compound rather than staying trapped in individual labs.

The Structure of Quantization Damage in LLMs: Why the Next Bit Should Be Spent Globally

How to spend extra precision budget when shrinking AI models

When AI models are compressed to run faster and cheaper, the damage isn't concentrated in a few critical layers—it spreads across roughly half the model's layers. Counterintuitively, applying finer-grained compression uniformly across the entire model recovers accuracy better than surgically fixing the layers that seem most broken, outperforming targeted repairs by 21–52 percentage points.

As companies deploy larger language models on phones, servers, and edge devices, quantization compression is essential to cut costs and latency. This finding changes how engineers should allocate limited precision budgets: instead of hunting for problem layers, spreading improvements evenly across the model works better in practice and is simpler to implement. This could reduce the engineering overhead of tuning quantization for each new model.

On the Reliability of Generative Augmentation: A Wasserstein-Based Theoretical and Empirical Study

When synthetic data helps machine learning, and when it doesn't

Researchers created a mathematical framework to predict when artificially generated data actually improves classification accuracy on imbalanced datasets. They found that higher-quality synthetic data doesn't always lead to better predictions—what matters is how closely the generated data matches the real data's distribution, measured by a metric called Wasserstein discrepancy.

Machine learning teams routinely use synthetic data to fix imbalanced datasets, but have lacked clear guidance on which generation methods work best. This framework provides a principled way to evaluate synthetic data quality before deploying it, potentially saving teams from investing time in high-fidelity generators that won't improve actual performance. It also shows that simpler oversampling methods are sometimes more reliable than complex generative models—a finding that could reshape how practitioners choose their augmentation strategy.

Benchmarking Peptide-Protein Affinity Prediction Across Peptide and Target Shifts

Testing whether AI can predict drug-like peptide binding when it sees new targets

Researchers tested ten different methods for predicting how strongly peptides bind to proteins, using 11,349 binding measurements split into three realistic scenarios: recognizing patterns in similar peptides, making predictions within known targets, and predicting binding to entirely new target proteins. The best method changed depending on the scenario—fingerprints worked best for familiar targets, but a model called HELM-BERT performed better when targets were completely new. Performance dropped significantly (from 0.67 to 0.53 correlation) when moving from known to unknown targets, showing that current methods struggle with genuine generalization.

Drug discovery relies on predicting how experimental molecules will bind their targets before expensive testing begins. This work exposes a critical gap: most peptide-binding models are benchmarked in unrealistic conditions and would fail in the real world, where researchers must predict binding to new disease targets they've never seen before. The findings demand that future benchmarks test what actually matters—whether methods can handle unfamiliar targets—and reveal which representation strategies hold up under that harder test.

BLOOM-WILT: Logit Tilting for Behaviour Elicitation in Automated LLM Auditing

Finding hidden safety failures in AI models through smarter questioning

Researchers developed BLOOM-WILT, a system that finds rare problematic behaviours in language models far more efficiently than existing auditing methods. By strategically adjusting how the model generates text and adapting its questioning approach across multiple conversation turns, the system increased detection of harmful outputs from 51% to 100% in some cases—without requiring expensive model retraining.

Language models deployed to millions of users encounter rare failure modes that standard testing never catches. BLOOM-WILT makes it cheap and practical to continuously hunt for these hidden safety problems after deployment, meaning developers can catch and fix harms that would otherwise slip through to real users. The system's rankings also revealed that some models previously thought safer than others actually weren't—a correction that affects which systems get deployed.

Quantum Simulation of Markovian and Non-Markovian Open Quantum Dynamics in Heavy-Ion Collisions

Using quantum computers to model how particles remember their past in collisions

Physicists have developed a method to run quantum computers that simulate how particles behave in extreme collisions, including cases where particles remember their history—something previous simulations couldn't capture. The approach works by adding a special helper system that tracks this memory and then removing it to recover the full behavior, and it cleanly transitions to simpler models when memory effects become negligible.

Heavy-ion collisions at facilities like the Large Hadron Collider create extreme conditions that reveal fundamental physics, but are hard to simulate because particles don't forget their past interactions instantly. This framework opens the door to using next-generation quantum computers to model these collisions more accurately, potentially unlocking new insights into how matter behaves under the most violent conditions in nature.

Beyond the Payload: How User Invocation Shapes Coding Agent Vulnerability to Repository Poisoning

How the way you ask an AI coder to work shapes whether it gets hacked

The way developers ask AI coding agents to do work—what task, how detailed the instructions, what rules to follow—dramatically changes whether poisoned code repositories can attack those agents. A new benchmark of 1,920 test cases found that certain task types create silent vulnerabilities where malicious code runs undetected, while unclear or rambling prompts can accidentally protect against attacks by making the poison harder to activate.

As companies increasingly hand off coding work to AI agents pulling from repositories they don't fully control, understanding how simple invocation choices affect safety is critical. A developer asking for test execution instead of general setup could expose their system to attack 4.5 times more, and they'd likely never notice. This work gives teams concrete guidance on safer ways to phrase their requests and which tasks pose the highest risk.

A Model with No Head and Many Thoughts

Letting AI think in continuous space instead of forcing words at every step

Researchers found that large language models can reason more effectively when they skip the expensive step of converting thoughts into words during intermediate reasoning. By working directly in continuous mathematical space during chain-of-thought steps—and only converting to words at the end—the method improved reasoning accuracy while cutting computational cost per step.

Language models spend enormous compute power converting every intermediate thought into discrete tokens, even though these internal reasoning steps are never seen by users. This work shows those internal steps don't need to be tokenized at all, potentially making AI systems faster and cheaper to run while improving their ability to solve hard problems.

Optimal Block Time for AMM Liquidity Providers under Jump-Diffusion Prices

Why making blockchain blocks faster doesn't always help liquidity providers

When prices jump suddenly instead of moving smoothly, making blockchain blocks faster stops helping liquidity providers avoid losses at a certain point. Researchers found that roughly one-quarter of losses at Ethereum come from these sudden price jumps that no block speed can prevent, and this fraction grows even larger on faster chains like Solana.

Blockchain developers often assume faster blocks help protect traders who provide liquidity to exchanges, but this research shows there's a hard limit to what speed can achieve. The optimal block time turns out to be around 8 seconds regardless of how big the pool is or how volatile prices are—meaning some losses are structural to markets with sudden price movements and cannot be engineered away.

Properties of the \mathcal V-Monoid of Weighted Leavitt Path Algebras

When do algebraic structures built from weighted graphs behave predictably?

Mathematicians studying weighted Leavitt path algebras—algebraic structures built from graphs with numbered edges—have identified when certain key properties hold or fail. The work characterizes exactly when these algebras can be simplified without losing information, and when their building blocks can be cancelled out like numbers in multiplication.

Leavitt path algebras appear in operator theory, symbolic dynamics, and quantum physics. Understanding when these algebras have predictable structural properties lets mathematicians and physicists apply them reliably in theory and computation, and simplifies the problem of determining when two seemingly different weighted graphs produce equivalent algebraic structures.

ContextPilot: Teaching Agents for Proactive Context Management via Fine-grained RL

Teaching AI agents to organize their own memory while solving complex tasks

Researchers created ContextPilot, a system that lets AI language models actively manage and compress their own working memory as they solve multi-step problems. The approach adds new memory-management tools and a smarter training method that rewards the most impactful decisions, allowing models to reach better answers while keeping their context 30–50% smaller than before.

As AI agents tackle longer and more complex tasks, they accumulate massive amounts of context that slows them down and costs more to run. By teaching models to edit their own memory intelligently, ContextPilot makes them faster and cheaper to operate without sacrificing accuracy—a practical gain for any real-world AI system handling lengthy customer conversations, research queries, or multi-step planning.

An Anonymized Urn-Based Experimental Dataset on Decision-Making under Risk and Ambiguity

How people bet differently when odds are clear versus murky

Researchers collected 4,486 decisions from 246 people choosing how much to wager on colored balls drawn from urns—sometimes with known odds, sometimes with unknown odds. The dataset reveals how people's willingness to pay shifts when uncertainty becomes ambiguous rather than simply risky, with online participants also rating how uncertain they felt about each choice.

Understanding how people behave under ambiguous uncertainty matters for everything from financial regulation to insurance pricing to public health policy, where real decisions often involve incomplete information. This dataset is large and detailed enough that researchers can now test competing theories about ambiguity-aversion side by side, and replicate findings that might otherwise stay trapped in individual labs.
