Abstract: The absence of low-frequency (LF) components in seismic records leads to nonuniqueness in inversion, making the building of a reasonable LF model crucial for achieving high-precision ...

Abstract: To alleviate the computational challenges of reverse time migration (RTM) in the frequency domain, this article constructs preconditioners based on the deep learning (DL) algorithm to ...

How do you send drugs to specific parts of the body so they do their job and avoid causing side effects elsewhere? According to researchers at Stanford University, the answer is a combination of ...

The trouble with many drugs is that they go where they shouldn't, producing unwanted side effects. Psychiatric drugs might cause dissociation, painkillers can induce nausea and chemotherapy often ...
