Research on Time Scale of Cesium Atomic Clocks Based on Kalman Plus Weights Algorithm

Abstract: High-performance atomic clocks provide the foundation for precise time measurement. Common high-performance atomic clocks in time-keeping laboratories include hydrogen masers and cesium ...

Stress-triggered protein clusters reveal how cells sort damaged cargo

Inside every cell, a cleanup operation runs around the clock. Proteins are constantly damaged by wear and tear. Some can be repaired, while others must be dismantled and recycled. When this system ...

Fusion Graph Structure Learning-Based Multivariate Time Series Anomaly Detection With Structured Prior Knowledge

Abstract: Multivariate time series anomaly detection (MTSAD) plays a crucial role in the Internet of Things (IoT) to identify device malfunction or system attacks. Graph neural networks (GNN) are ...

Using atomic nuclei could allow scientists to read time more precisely than ever

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.
