That's the efficiency of the device, not the laser. This device does not include a laser. That said, I don't know of any diode lasers that are that bad. Lasers for this fiber are probably 50%+ efficient and even the high frequen

Simple answer: no. Ferromagnetic hysteresis increases with temperature, and the hysteresis here is stronger at lower temperatures. The amount of hysteresis they see at low temperatures is also too much to explain with undetected contamina

The biggest trip-up is the pronunciation of "prototypically", and you had "typically" in your original. Maybe it's overfitting to a stilted proto-typically? Could try with a different, less similar sentence

Much more likely they had a strict time limit (internally or externally imposed) on what they considered biodegradable. If you make it stronger but thinner, bacteria can break it up much faster which leads to faster breakdown. By comparis

Misleading way of looking at it. Lithium and sodium are not the major cost (or weight, or volume) inputs to making batteries, and crustal occurrence is very distantly related to cost. We mine things from places with 100x-1mx higher concen

The most common GPU on steam stats is a 3060. The AMD 7800/7700 do 90% and 70% better on benchmarks. So if you have either of those, you're getting nearly twice the FPS that the most common steam user would see.
