Pulsar wind nebula inside supernova remnant explored with Chandra
May 30, 2026 report Pulsar wind nebula inside supernova remnant explored with Chandra Tomasz Nowakowski Author Gaby Clark Scientific Editor Robert Egan Associate Editor Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of the observational campaign, presented in a research paper published May 20 on the arXiv preprint server,...
VITO: Vascular Geometry and Blood Flow Estimation Using Inverse Topology Optimization
arXiv:2606.05487v1 Announce Type: new Abstract: Computed Tomography Angiography (CTA) is widely used to reconstruct vascular geometry from projection measurements, with conventional approaches such as Filtered Back-Projection (FBP) and Iterative Reconstruction (IR) forming the clinical standard. Blood flow is subsequently estimated through Computational Fluid Dynamics (CFD) simulations, which require vascular geometry and boundary conditions to be specified a priori.
Stimulus-Specific and Generalized Taste Aversion Behaviors and Their Relationship to Cortical Dynamics
Aversive taste behaviors, such as gaping, are commonly viewed as fixed, hard-wired responses important for ejecting potentially toxic tastes from the mouth. Yet, taste responses are highly susceptible to modulation by experience and context; for instance, conditioned taste aversion (CTA), a form of learning in which rats are made to respond aversively to a sweet taste after it has been paired with gastric malaise, can cause gaping to previously acceptable tastes. Here, we compare aversive...
Counterfactual Trace Auditing of LLM Agent Skills
Announce Type: replace Abstract: Large Language Model agents are increasingly augmented with agent skills. Current evaluation methods for skills remain limited. Most deployed benchmarks report only pass rate before and after a skill is attached, treating the skill as a black box change to agent behavior.
Meet the big winners of 2026 oil price volatility — and why their strategies are now shifting focus
The surge in oil prices and ongoing volatility have netted major gains in a corner of the market that rarely captures headlines: quantitative trend-following hedge funds. Quantitative trend-followers — also known as commodity trading advisors (CTAs) or managed futures funds — use complex machine-learning algorithms, statistical analysis and factor-based modelling to identify price trends across futures markets, including equities, bonds, commodities and currencies. The spike in commodity...
Castor: CERN Advanced STORage Manager
The CERN Advanced STORage manager (CASTOR) is a hierarchical storage (i.e. has disk and tape) management system which was developed at CERN for archiving physics data (with very large data volumes, see the plot on the right). Files can be stored, listed, retrieved and remotely accessed using CASTOR command-line tools or user applications that were developed using the CASTOR API. CASTOR provides a set of access protocols such as XROOT (the main and recommended protocol) and GridFTP.
Major travel disruption to and from Heathrow airport after burst pipe halts trains
Major travel disruption to and from Heathrow airport after burst pipe halts trains A signal failure caused by flooding at Heathrow Terminals 2 and 3 means there are no train services to Heathrow today - Bookmark - CommentsGo to comments Passengers are facing major travel disruption travelling to and from Heathrow airport after a burst pipe halted train services. Transport for London said there were no services on the Elizabeth Line between Hayes and Harlington and Heathrow due to a signal...
BiSegMamba: Efficient Bidirectional Tri-Oriented Mamba for 3D Medical Image Segmentation
Announce Type: new Abstract: Accurate 3D medical image segmentation requires both long-range volumetric context and fine boundary preservation. CNN-based methods have limited global dependency modeling, while Transformer-based models are often computationally expensive for dense 3D inputs. Recent Mamba-based methods provide an efficient alternative, but existing volumetric designs still depend on repeated high-resolution scanning, forward-only sequential modeling, and fixed directional...
