New research suggests that Earth's inner core may not be as solid as previously believed. Scientists studying seismic waveforms have discovered structural changes in the core, which challenge ...

Full waveform inversion (FWI) is commonly used in seismic exploration to calculate parameters of the medium, such as velocity, from the signal as it passes through the medium. To obtain an accurate ...

Shear wave velocity is an essential elastic rock parameter for reservoir characterization, fluid identification, and rock physics model building. However, S-wave velocity logging data are often ...

To find out, the team used whole-Earth oscillation data from 104 past earthquakes to create a detailed 3D model of the upper ...

They were cooler than the LLSVPs, so seismic waves moved through them more quickly. However, the new model showed that while seismic waves' velocity dipped when they reached LLSVPs, the waves didn't ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Detailed price information for Pulsar Helium Inc. (PLSR-X) from The Globe and Mail including charting and trades.

In recent years, methods for seismic velocity model building (VMB) based on the nonlinear mapping capabilities of deep learning have been emerging, particularly for the seismic reflection waveforms of ...

Last week, something potentially enormous happened for artificial intelligence: The Chinese company DeepSeek released an open-source, free-to-use reasoning model that is — by crude measures ...

On January 20, DeepSeek, a relatively unknown AI research lab from China, released an open source model that’s quickly become the talk of the town in Silicon Valley. According to a paper ...

Tesla TSLA.O launched a redesigned version of its best-selling Model Y crossover in the United States, Canada and Europe on Thursday, weeks after it was first released in China. The refreshed ...
