A bug was recently identified in the ModeMap.py script whereby normal-mode coordinates were scaled internally by 1/sqrt(N a), leading to U(Q) curves that were inconsistent with the harmonic mode ...

Abstract: The broadband impedance spectrum (BIS) is an effective technique for localizing defects in coaxial cables, yet existing analytical approaches, such as the fast Fourier transform (FFT) and ...

As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure ...

To a nonmathematician, having the letter "i" represent a number that does not quite exist and is "imaginary" can be hard to wrap your head around. This means they are made of both real numbers and the ...

To a nonmathematician, having the letter “i” represent a number that does not quite exist and is “imaginary” can be hard to wrap your head around. If you open your mind to this way of thinking, ...

Optical forces on small particles are conventionally produced from the intensity or phase gradient of light. Harnessing the imaginary Poynting momentum (IPM) of light to generate nontrivial forces ...

The Riemann hypothesis is the most important open question in number theory—if not all of mathematics. It has occupied experts for more than 160 years. And the problem appeared both in mathematician ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. The calculation of EI requires dimensionality reduction. By ...

The Hall thruster (HT) is a standard spacecraft electric propulsion system that uses crossed electric and magnetic fields to ionize and accelerate propellant (Goebel and Katz, 2008; Boeuf, 2017).

Department of Computer Science, University of York, York, UK. Kolmogorov complexity is a unique formalisation of complexity which quantifies “information” from an algorithmic point of view [1] and has ...
