Inference Cost Attacks for Retrieval-Augmented Large Language Models
arXiv:2606.02643v1 Announce Type: new Abstract: Retrieval-Augmented Generation (RAG)-enhanced LLM systems, while powerful, introduce substantial inference costs due to the inclusion of an extra multi-stage pipeline that dynamically retrieves and synthesizes information from external knowledge sources. This high operational cost exposes a critical vulnerability to Inference Cost Attacks (ICAs). However, existing ICAs often rely on the impractical assumption of direct prompt manipulation.
30 motorists caught for queue cutting, other traffic offences at Woodlands Checkpoint
30 motorists caught for queue cutting, other traffic offences at Woodlands Checkpoint Fifteen motorists were referred to the traffic police for further action. SINGAPORE: A total of 30 motorists have been caught over the Vesak Day long weekend for committing traffic offences and engaging in dangerous road behaviour, including queue cutting, the Immigration and Checkpoints Authority (ICA) said on Friday (Jun 5). ICA said its officers had stepped up traffic enforcement operations at Woodlands...
Application of Fractional Polynomial Model Based on Bayesian Criterion in Cerebrovascular Diseases: A Robust Framework for Occlusion Simulation and Topology Reconstruction
arXiv:2606.06507v1 Announce Type: new Abstract: The internal carotid artery (ICA), especially its cervical segment (ICA-C1), holds significant importance in the diagnosis of cerebrovascular diseases. Traditional polynomial fitting methods often encounter problems such as order selection, overfitting, and oscillation.
Enhancing Blind Source Separation with Dissociative Principal Component Analysis
arXiv:2411.12321v2 Announce Type: replace Abstract: Principal component analysis (PCA) and its sparse variants (sPCA) are widely used as a precursor to independent component analysis (ICA) for blind source separation (BSS). However, sPCA typically relies on a deflation strategy that extracts components sequentially and imposes orthogonality between them. When the underlying sources overlap, this discards the cross component structure that ICA depends on, degrading separation.

About 10,000 cars stolen or broken into in Melbourne each year
Victorian vehicle theft rates rise to buck trend across mainland Australia Thu 4 Jun 2026 at 2:37pm In short: Motor vehicle theft has declined in every mainland Australian state except Victoria, which has notched up a 25 per cent increase in claims. Victorian vehicle theft claims are concentrated in greater Melbourne, which recorded 10,400 claims between 2024 and 2025, totalling $205 million. Political analysts say crime is set to be a key topic ahead of the Victorian state election in November.
Graph-Guided Universum Learning in Generalized Eigenvalue Proximal SVMs for Alzheimer's Disease Classification
arXiv:2606.04699v1 Announce Type: new Abstract: Early and accurate detection of Alzheimer's disease (AD) is important for timely intervention and disease management. Generalized Eigenvalue Proximal Support Vector Machine (GEPSVM) and its Universum-based variants have shown promising results for AD classification. However, existing methods treat Universum samples as independent points and do not consider the geometric relationships among them.
Energy transport corridors to Europe boosted by AI and new digital systems
AI and new digital technologies are key to the urgently needed alternative energy trade routes through the Southern Gas Corridor and the Middle Corridor systems connecting the Caspian and Europe. The Southern Gas Corridor and the rapidly developing Middle Corridor trade routes connecting Asia to Europe through the Caspian region are emerging as strategic energy transport bridges amid global disruptions, but these energy transit systems and their security require urgent investments in...
Scalable Uncertainty Quantification for Extreme Weather Forecasting via Empirical Neural Tangent Kernels
arXiv:2606.02886v1 Announce Type: new Abstract: Deep learning weather models now match numerical weather prediction accuracy while running orders of magnitude faster, but produce deterministic forecasts without uncertainty estimates, a critical gap for high-stakes decisions during extreme weather events. This paper proposes Neural Tangent Kernel-based uncertainty quantification (NTK-UQ) using last-layer empirical features. Theoretical analysis predicts that UQ quality is...
