Atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

A seismic attenuation estimation approach is proposed based on multivariate variational mode decomposition (MVMD). MVMD, as a multivariable or multichannel signal processing tool, can extract several ...

Using unweighted frequency maps (n-map), denoting the number of VTAs or lesions overlapping at a given voxel, the raw average maps were thresholded to include only voxels with a minimum of 10% ...

Google Maps will display the name “Gulf of America” instead of the “Gulf of Mexico” for U.S. users once official government sources are updated to reflect the name change ordered by ...

Google Maps will reflect President Trump’s changes in the United States and will show the Gulf of America and Mount McKinley, Fox News Digital has learned. Google will make the changes once ...

Fuel something bigger with ZOA, the energy drink designed to power your day with clean, effective ingredients.Each can is packed with caffeine from green tea, essential electrolytes, branched ...

Abstract: Spectrum cartography (SC) aims to construct a global radio-frequency (RF) map across multiple domains, e.g., space, frequency and time, from sparse sensor samples. Recent state-of-the-art SC ...

Each cavity is driven by a high-power klystron, which is a tube containing electron beams. The electron beams are intensity-modulated to a frequency of 400 MHz, or 400 million oscillations per second.

Method: In this paper, we propose a Residual Dense Block and Deep Convolutional Generative Adversarial Network (RDB-DCGAN) data augmentation model based on the DCGAN and RDB, which takes ...
