DR. CAMPBELL has attempted with great courage a very ambitious task—that of discussing critically the fundamental conceptions, propositions, and methods of the science of physics. A rough idea ...

In the context of quantum mechanics and information, "magic" is a key property of quantum states that describes the extent to which they deviate from so-called stabilizer states. Stabilizer states ...

During drilling, a rotary steerable system (RSS) is affected by vibration, rotation, and other random noises. This paper presents a random weighting adaptive estimation of model errors on attitude ...

The US Congress has passed a bill that cancels nearly eight billion dollars of foreign aid. It also slashes more than a billion dollars of funding for US public broadcasting. Critics say it takes ...

The phase adaptive stabilization system (PASS), functioning as an adaptive optics system of radio frequency (RF), is a key technology for achieving the next generation of single-dish ...

Errors can be classified into two types: systematic and random. Systematic errors are consistent and predictable deviations from the true value, caused by factors such as calibration bias ...
