With a new MRI technique that shows both heart tissue and blood flow simultaneously, physicians can see where heart defects occur and precisely plan to repair them, according to new research published ...

Cryogenic 4D-STEM reveals how charge density waves form, fragment, and persist across a phase transition. (Nanowerk News) Electronic order in quantum materials often emerges not uniformly, but through ...

In this video, we compute and visualize the electric field from two charges using Python, showing how to calculate field vectors and plot the results clearly. Perfect for learning electrostatics, ...

Background: While 4D contrast-enhanced computed tomography (CT) is used to plan cardiovascular interventions such as transcatheter valve replacement, it is not yet routinely used to characterize ...
