Independence and Domination on Bounded-Treewidth Graphs: Integer, Rational, and Irrational Distances
new Abstract: The distance-d variants of Independent Set and Dominating Set problems have been extensively studied from different algorithmic viewpoints. In particular, the complexity of these problems are well understood on bounded-treewidth graphs [Katsikarelis, Lampis, and Paschos, Discret. Math 2022][Borradaile and Le, IPEC 2016]: given a tree decomposition of width t, the two problems can be solved in time $d^t \cdot n^{O(1)}$ and $(2d + 1)t \cdot n^{O(1)}$, respectively.
Welfare Maximization in Bilateral Trade: Improved Approximation Guarantees Beyond the Fixed Price Barrier
Announce Type: new Abstract: We study the setting of welfare maximization in bilateral trade, where the values of both the buyer and the seller are drawn from independent distributions. Our goal is to maximize social welfare. In this setting, fixed price mechanisms have been extensively studied.
Reconstructing Synthetic SDO/AIA 193 A EUV Images from He I 10830 A Observations with Diffusion Model Translator
arXiv:2606.08652v1 Announce Type: cross Abstract: Routine full-disk EUV imaging has been available only since the modern era, such as SOHO and SDO. To extend EUV coronal context into earlier periods, we leverage the multi-decade availability of full-disk \HeI{} observations, whose absorption is modulated by coronal irradiance and magnetic topology and is widely used as a proxy for open-field regions. We present a diffusion-based conditional image translation framework, Coronal Hole-aware...
The World's Fastest Matching Engine Algorithm
arXiv:2606.01183v2 Announce Type: replace Abstract: A single CPU core sustains 32 million order messages per second at sub-microsecond median wire-to-wire latency, up to 11 times faster than the best open-source matching engines on identical hardware. Scaled out, a single 96-core commodity server (~$1,630/month) sustains ~640 million messages per second across 10,000 symbols, over 20 times the provisioned capacity of the U.S. consolidated quote feed. We reach these numbers by attacking the...
Amplified Arctic iceberg traffic reshapes benthic biodiversity
Abstract The Arctic is undergoing rapid warming, resulting in retreating sea ice and glaciers1, yet how cryospheric changes propagate into the deep ocean remains poorly understood2. Here we identify a climate-driven mechanism linking accelerating glacier disintegration to an increase in deep-sea hard-bottom habitats far beyond calving fronts. Seafloor observations in Fram Strait show a localized increase in the density and patchiness of dropstones delivered by debris-laden icebergs.
The Unreasonable Redundancy of Nature's Protein Folds
The Unreasonable Redundancy of Nature's Protein Folds Over the last few years, deep neural networks have made generative language modeling dramatically more powerful, giving us large language models. A similar leap happened for continuous modalities like images and videos.
Solar Energy Saves Europeans $135M a Day
Solar Energy Saves Europeans $135 Million A Day Support CleanTechnica's work through a Substack subscription or on Stripe. You would think the fighting in the Middle East and the closure of the Strait of Hormuz would be sending the price of oil and methane for power plants in Europe soaring, and cause the price people and businesses pay for electricity to increase. You would be right, except for one thing.
Structured interactions improve distributed coordination beyond model scaling in a real-world multi-robot system
arXiv:2605.30383v1 Announce Type: new Abstract: Scaling individual robot capabilities is common but costly. Here we investigate a system-level design question in real-world multi-robot coordination: given matched hardware budgets, does restructuring communication among robots yield larger gains than increasing onboard model size? Using a representative transport-and-mapping task with 10 physical robots (5 runs per condition, 60 runs total), we find that switching from fully connected to...
Off the Record: Politics, protests and dead flamingos dominate EU-Western Balkans summit
Euronews Europe editor Maria Tadeo provides highlights and analysis from the EU-Western Balkans summit held this week in her signature newsletter Off the Record. When I launched this newsletter, I promised you zeitgeist, so here's the zeitgeist — I am filing this at ungodly hours, from a flat in Tivat, on the coast of Montenegro, on five hours' sleep, praying for no typos and my keyboard on fire. But oh boy how I love this job.
LRAgent: Efficient KV Cache Sharing for Multi-LoRA LLM Agents
Announce Type: replace Abstract: Role specialization in multi-LLM agent systems is often realized via multi-LoRA, where agents share a pretrained backbone and differ only by lightweight adapters. Despite sharing base model weights, each agent independently builds and stores its own KV cache for the same long, tool-augmented trajectories, incurring substantial memory and compute overhead. Existing KV cache sharing methods largely overlook this multi-LoRA setting.
