Low-cost MRI paired with AI produces high-quality results

A magnetic resonance imaging device built with off-the-shelf parts and paired with AI matched the performance of high-end MRI machines, according to a study published Thursday that could pave the way for greater access to ...

Liquid

Liquid is one of the three classical states of matter (the others being gas and solid). Like a gas, a liquid is able to flow and take the shape of a container. Some liquids resist compression, while others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena.

The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.
