New Integrated Photonics Breakthrough Paves the Way for Compact, Low-Noise Signal Generation Imagine transferring massive ...

Fewer isolated pulsars are available for X-ray pulsar navigation, and they are unevenly distributed spatially. In contrast, the number of available binary pulsar for navigation is promising. However, ...

To reduce the measurement noise and the correlation between the process and measurement noises caused by time-differenced measurement, we study an X-ray pulsar navigation method using ...

Experts have explained how to tell the difference between flu and human metapneumovirus (HMPV), as cases appear to be rising in the UK. When you're seeing Chinese hospitals being overflowed in ...

We correlated the monthly rate of relative change in normalized differenced vegetation index (NDVI) from advanced very high resolution radiometer (AVHRR) data to the rate of change in atmospheric CO₂ ...

Fatty liver diseases (FLD) have recently attracted much attention due to the increasing prevalence and liver-related morbidity and mortality. The NAFLD (Non-alcoholic Fatty Liver Disease) refers to ...
