As ShakeAlert, the earthquake early warning system for West Coast of U.S., begins its transition to operational public alerting, we explore how post-alert messaging might represent performance. Planned can provide timely, crucial information both emergency managers and ShakeAlert operators as well calibrate expectations among various publics or user groups inform their responses future alerts. There is a concern scientists that false alerts may negatively impact trust in system, so quickly...

Abstract. To exploit full metric quality of optical satellite imagery, precise georeferencing is necessary. A number sensor orientation models designed to the potential images have been developed over past decades. In particular, generic attract more interest as they take account physical imaging process by adopting time dependant orbit and interior (IO) information provided imagery vendors. The IO parameters varies for different satellites has significant impact on performance....

Multimodal Large Language Models (MLLMs) have made significant strides in visual understanding and generation tasks. However, generating interleaved image-text content remains a challenge, which requires integrated multimodal abilities. While the progress unified models offers new solutions, existing benchmarks are insufficient for evaluating these methods due to data size diversity limitations. To bridge this gap, we introduce GATE OpenING (OpenING), comprehensive benchmark comprising 5,400...
