Flight forced to U-turn midway to Spain after Bluetooth bomb scare

Flight forced to U-turn midway to Spain after Bluetooth bomb scare A United Airlines from to Mallorca, Spain, was forced to make a diversion due to a security alert A United Airlines flight bound for Spain was forced to make an emergency U-turn after a mischievous teenager labelled a Fitbit device 'bomb' and triggered a full-scale security incident. The 16-year-old's fitness tracker was flagged by security around an hour and a half into a transatlantic flight from New Jersey to Mallorca,...

Constraints on long-range neutrino interactions from a variety of $U(1)^\prime$ symmetries using atmospheric neutrinos at IceCube DeepCore

arXiv:2606.03443v1 Announce Type: cross Abstract: Neutrino oscillation experiments provide a unique probe to search for the physics beyond the Standard Model. In this work, we search for a broad class of anomaly-free flavor-dependent $U(1)^\prime$ symmetries using atmospheric neutrino data for the first time. Gauging these $U(1)^\prime$ symmetries give rise to ultra-light vector gauge bosons mediating long-range interactions (LRI) of neutrinos.

Virgin flight u-turns after mid-Atlantic engine failure at 35,000 feet

Virgin flight u-turns after mid-Atlantic engine failure at 35,000 feet The Virgin Atlantic flight departed London on Saturday afternoon and was heading towards Jamaica when one of its engines failed high over the North Atlantic Ocean A Virgin Atlantic plane bound for Jamaica was forced U-turn over the Atlantic Ocean before landing in Ireland after its engine suddenly failed mid-flight. Flight VS165 departed London Heathrow at 4:12pm on Saturday and was almost three hours into the journey...

Beyond Convolution: Advancing Hypergraph Neural Networks with Hypergraph U-Nets

new Abstract: Convolutions have successfully transitioned from image processing to the complex realm of non-Euclidean higher-order domains, particularly in hypergraphs. Despite the success in convolution, the exploration of a popular architecture named U-Net remains largely unexplored for hypergraph data due to the lack of well-defined pooling and unpooling operations. This work pioneers the study of U-Net architectures for hypergraph data, addressing the critical challenge of designing...

Multi-planar 2D-U-Net Segmentation of 3D-CT Abdominal Organs augmented by Spatial Occurrence Maps

arXiv:2606.07717v1 Announce Type: cross Abstract: This work proposes a lightweight 2D-U-Net-based framework for segmenting five abdominal organs in large field-of-view 3D CT scans. The method combines coarse-to-fine segmentation, predictions from multiple anatomical planes, and additional fuzzy 3D spatial maps that provide anatomical location cues to improve segmentation accuracy.

U-Cast: A Surprisingly Simple and Efficient Frontier Probabilistic AI Weather Forecaster

Announce Type: replace-cross Abstract: AI-based weather forecasting now rivals traditional physics-based ensembles, but state-of-the-art (SOTA) models rely on specialized architectures and massive computational budgets, creating a high barrier to entry. We demonstrate that such complexity is unnecessary for frontier performance. We introduce \ours, a probabilistic forecaster built on a standard U-Net backbone trained with a simple recipe: deterministic pre-training on Mean Absolute Error...

FIFA U-turns on water bottle policy in US, Canada stadiums after backlash

FIFA U-turns on water bottle policy in US, Canada stadiums after backlash New York Mayor Mamdani was among those critical of FIFA’s decision to ban water bottles at World Cup stadiums. FIFA has made changes to its stadium policy, allowing fans to bring disposable water bottles into match stadiums after a ban earlier this week drew backlash from supporters and tournament host city officials. FIFA’s initial policy permitted fans to carry empty, transparent, reusable plastic bottles up to 1...

Development of flash lithium evaporators for NSTX-U

arXiv:2606.00777v1 Announce Type: new Abstract: We present results of in-vacuo refill and operation of a lithium evaporator in LTX-$\beta$ as the culmination of a larger design basis for a flash lithium evaporator (f-LITER) for wall conditioning in the National Spherical Torus Experiment Upgrade (NSTX-U). The new f-LITER is intended to deliver fresh lithium to plasma-facing components (PFCs) in both the upper and lower-divertor as well as the center-column and outboard regions for...
