emitting

The objects themselves don't emit light, where as the DNA is assumed to already be emitting sound (vibration) that needs to be amplified.

Wouldn't material with a half life of 1500 years necessarily not be emitting much of any radiation?

In that context, even a small amount of bound material may be continuously emitting where one is always getting a dose.

It should also be a required feature in cars to show excaclty what pollution they are emitting, along with common health effects.

All 4 of these processes are probably emitting logs to disk somewhere, too.

Etendue shouldn't be too much of a concern because we are emitting onto a relatively large space.

One example is the compiler may have a logic bug that violates an internal invariant resulting in an ICE (instead of emitting incorrect code).

None of light-emitting-diodes, liquid-crystal-displays, or cathode-ray-tubes rely on the photoelectric effect.

This is also a situation where you don't want bad actors emitting in the wrong frequency band, at the wrong time, with the wrong power, etc..

Because there is an enormous amount of mass that we can detect via gravitational lensing, but which is not emitting or absorbing light.

Meaning, if we just stopped emitting greenhouse gases, OA would stop increasing.

The main import, to me, is: what is the energy density of this energy, and if emitting, how much pollution?

We have a "recycling cavity" behind the phosphor plates that reflects "backward" emitting photons.

Wikipedia [2] appears to be reporting LED efficiencies of 20% - 39%, and one research group [2] reports on getting over 100% efficency, with an LED emitting "more optical power than the electrical power it consumes," although at very low power levels.

Whenever the word "white" is used in a scientific or quasi-scientific context, it should probably be specified whether the speaker means "perceived by the human eye to be white", or "emitting a continuous spectrum across all frequencies of visible light", or something in between.
