Abstract: This letter proposes a novel three-dimensional geometry-based stochastic model (GBSM) for multiple-input-multiple-output (MIMO) channels in unmanned aerial vehicle (UAV) air-to-ground (A2G) ...

A performance comparison between the new Porsche Taycan Turbo GT and the Tesla Model S Plaid. This video examines acceleration, handling, and technology to see how Porsche’s latest electric sports ...

Blind and low-vision programmers have long been locked out of three-dimensional modeling software, which depends on sighted users dragging, rotating and inspecting shapes on screen. Now, a ...

Researchers confirmed that Rapa Nui’s moai statues could “walk” upright using a rocking motion, aided by rope and just a few people. Experiments with replicas and 3D models revealed design features ...

Abstract: Masked image modeling (MIM) with transformer backbones has recently been exploited as a powerful self-supervised pre-training technique. The existing MIM methods adopt the strategy to mask ...
