Coupled simulation of plasma-surface interactions during early stages of vacuum arcing
arXiv:2606.05893v1 Announce Type: new Abstract: We describe fully coupled simulations that bridge atomistic cathode dynamics and plasma formation during the earliest stages of vacuum arcing. The model combines molecular dynamics, finite element electrothermal calculations, electron emission and particle-in-cell plasma simulations via dynamic transfer of particles between the surface and plasma domains. Simulations of Cu nanoprotrusions reveal two routes to thermal runaway: direct Joule...
Logitech knows when to fold 'em
Logitech has unveiled the Mobi Fold mouse – a portable, foldable pointing device that could easily double as a replacement for a chunkier desktop version. It's the first foldable for Logitech, although alternatives have long been available. When you unfold it, it resembles something like Microsoft's Surface Arc mouse.
Logitech’s new Mobi Fold squeezes a lot of functionality into a tiny folding mouse
The Mobi Fold feels like a full-sized mouse when opened and includes a touch panel for scrolling. Logitech finally announced its new ultraportable travel mouse following leaked marketing images that spoiled the surprise last month. As the name implies, the Mobi Fold is a compact mouse that can fold in half using a hinge that can pivot about 130 degrees.
BRepCLIP: Contrastive Multimodal Pretraining on BRep Primitives for CAD Understanding
Announce Type: new Abstract: Learning representations of CAD models is a largely open problem. While 3D representation learning has flourished around point clouds and meshes, the native format of CAD - boundary representations BReps, which encodes exact parametric surfaces, curves, and their topology, has received little attention as a representation learning substrate.

Computex 2026: All the news and announcements
Computex 2026 is kicking off in Taipei, Taiwan this week, where Nvidia, AMD, Qualcomm, Intel, and other tech brands are announcing new laptops, handhelds, chips, and more. Nvidia unveiled RTX Spark, its first family of consumer PC chips, arriving in laptops and mini PCs starting this fall. Intel is launching two new custom chips made for handheld gaming devices, the Arc G3 and Arc G3 Extreme, which will power the upcoming Acer Predator Atlas 8. Qualcomm is taking aim at the MacBook Neo...
From Roofline to Ruggedness: Decomposing and Smoothing the GEMM Performance Landscape
arXiv:2605.29752v1 Announce Type: cross Abstract: Adjacent GEMM problems that differ by a single 128-element step in N can show 30% different throughput on the same GPU. This pervasive performance ruggedness - invisible to roofline analysis and peak-FLOPs intuition, yet dominant for every non-peak workload - is the subject of this paper. We propose performance ruggedness analysis as an analytical framework complementary to roofline: rather than summarizing GPU performance with a scalar...
Toxic HallucinAItions: Perturbing Prompts and Tracing LLM Circuits
arXiv:2605.30913v1 Announce Type: new Abstract: Large language models (LLMs) are increasingly deployed in conversational settings where user tone ranges from polite to adversarial or toxic, yet less is known about whether toxic language in otherwise semantically equivalent prompts can degrade factual reliability. We study how lexical and tone-based prompt perturbations affect the factual reliability of LLMs. Using controlled prompt variations across polite, random, and three toxicity levels,...

A 5.3-million-year-old deep-sea whale necropolis in the Diamantina Zone
Abstract Whale falls are biodiversity oases at seabeds1,2,3,4,5,6, yet their record from the oceans has remained sparse and fragmentary6,7. Here we report the discovery of a vast whale necropolis in the Diamantina Zone (4,616- to 7,001-m depth), extending about 1,200 km along the sea floor of the southeastern Indian Ocean. This area has a deep and extensive accumulation comprising five modern natural whale-fall communities and 476 fossil cetaceans recorded.
