Overview of the ALICE ITS3 Upgrade

Announce Type: new Abstract: The ALICE experiment will replace its three innermost tracking layers with the Inner Tracking System 3 (ITS3) during LHC Long Shutdown 3. This upgrade introduces the first fully cylindrical, wafer-scale silicon vertex detector, utilising Monolithic Active Pixel Sensors (MAPS) fabricated in a 65nm CMOS process. By thinning sensors to 50$\mu$m and bending them to radii as small as 19mm, the design achieves a self-supporting structure that eliminates traditional...

HYolo: An Intelligent IoT-Based Object Detection System Using Hypergraph Learning

Announce Type: new Abstract: This paper presents HYolo, an intelligent IoT-based object detection framework that integrates hypergraph learning into the YOLO architecture. Traditional YOLO-based object detection models primarily capture pairwise feature interactions and may fail to model complex high-order relationships among objects and contextual features. To address this limitation, HYolo incorporates hypergraph learning to capture richer contextual dependencies and improve object...

NGram-MoSE: Efficient Remote Sensing Super-Resolution via N-Gram Context and Mixture-of-Experts

Announce Type: new Abstract: Remote sensing applications for environmental monitoring and disaster management are frequently constrained by a spatial--temporal trade-off: imagery with fine spatial detail is often acquired less frequently, whereas more temporally available observations are typically coarser. Single-image super-resolution provides a practical means to enhance coarse imagery without changing acquisition schedules, yet many Transformer-based SR models remain computationally...

A prognostic human brain network for diffuse midline glioma

Abstract Diffuse midline gliomas (DMGs) are near-universally lethal tumours of the childhood central nervous system1,2. In animal models, DMGs form brain-wide integrated networks through neuron-to-glioma synapses3,4,5,6 and glioma-to-glioma gap junctional coupling3. This extensive connectivity robustly promotes the growth and invasion of DMG3,4,5,6,7,8,9 and other glial malignancies10,11,12 through paracrine mechanisms and direct neuron-to-glioma synapses.

Six roads to safety: A critical threshold for wildfire survival

Six roads to safety: A critical threshold for wildfire survival Sadie Harley Scientific Editor Robert Egan Associate Editor If your community was threatened by a wildfire, would you be able to quickly evacuate? A new study from UC Santa Barbara reveals that the number of roads out of a community may be one of the strongest predictors of wildfire fatalities, and that a surprisingly specific threshold separates high-risk communities from safer ones. Published in Proceedings of the National...

51% of U.S. adults say the American Dream is out of reach for most people right now: CNBC survey

Just over half of Americans say the American Dream is out of reach for most people right now, according to a new CNBC and SurveyMonkey American Dream Pulse Survey. Roughly 45% of respondents said the American Dream is only achievable for some people, and 6% said it's not in reach for anyone, according to a study of 4,130 U.S. adults, conducted May 6 to 11. The term "American Dream" was popularized in the 1930s by historian James Truslow Adams, who called it a "dream of a better, richer and...

Benchmarking Quantum Algorithmic Resilience for CVaR Portfolio Optimization: The Expressibility-Coherence Trade-off

Announce Type: cross Abstract: Quantum combinatorial optimization offers theoretical advantages for complex financial modeling, but physical implementation on Noisy Intermediate Scale Quantum (NISQ) devices is severely constrained by hardware topology. This study presents a hardware benchmarking analysis between a Hardware Efficient Variational Quantum Neural Network (HE-VQNN) and the Warm Start Quantum Approximate Optimization Algorithm (WS-QAOA) for a hybrid Mean Variance and Conditional...

Extreme heat is reaching Europe’s most northern cities. These mayors are determined to solve it

From Athens to Oulu, European mayors are among 50 worldwide teaming up to protect citizens against extreme heat. Last July, Antalya on the Turkish Riviera broke records when temperatures crept above a scorching 46°C. Home to more than 2.6 million people – and millions more tourists each summer – the Mediterranean city was long accustomed to heat.

Evaluating Factual Density in Multi-Source RAG: A Study in Medical AI Accuracy

arXiv:2605.31506v1 Announce Type: new Abstract: Retrieval-Augmented Generation (RAG) is the current industry standard for grounding AI in real-world facts. Traditional retrieval methods rely on keyword matching and topic proximity, ranking content based on how closely it sounds like the user's query. What they do not measure is how many verified facts the content actually contains.
