Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective ...

China’s Tianwen-2 spacecraft, which lifted off on 29 May 2025, is on course to attempt a touch-and-go sample grab from near-Earth asteroid (469219) Kamoʻoalewa this month. If the maneuver succeeds, ...

The ocean regulates Earth’s climate, supports immense biodiversity and sustains billions of livelihoods, yet it remains under-sampled across many regions ...

Abstract: This paper considers the detection of a distributed target in a partial observation scenario. A distributed target model is usually adopted when the target size is larger than the range bin, ...

Abstract: This paper considers the optimization problem for partially observable Markov decision processes (POMDPs) with the continuous state, observation, and action spaces. POMDPs with the discrete ...

Remote sensing image (RSI) interpretation typically faces challenges due to the scarcity of labeled data, which limits the performance of RSI interpretation tasks. To tackle this challenge, we propose ...

Cities are large emitters of methane, a potent greenhouse gas and precursor for tropospheric ozone. We use space-based observations to study nearly 100 cities with a total population of 1.18 billion ...

Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside some solid materials. These patterns can change how electricity flows ...

Here’s what you’ll learn in this story: The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it. While most physicists agree that human ...

Welcome to the official repository of our paper "RemoteSAM: Towards Segment Anything for Earth Observation"! Recent advances in AI have revolutionized Earth observation, yet most remote sensing tasks ...

Observational methods applied to natural or habitual contexts are scientific procedures that reveal the occurrence of perceptible behaviors, allowing them to be formally recorded and quantified. They ...
