A method of charged particle trajectory tracing, which is essentially an extension of that described by Birtles in 1972 to include time-varying fields, is described. Methods of error estimation and step-length optimization are given whic... AB Birtles - 《Journal of Physics D Applied Physics》...
Because it makes the kind of error common in the social sciences, I want to examine a passage from a recent article printed in Hillsdale College’s publicationImprimus.The article is “Restoring America’s Economic Mobility” by Frank Buckley and is in the September 2016 issue.It is also onl...

This paper presents the results of a systematic error analysis of these approximations to the exact coordinate transformations and the resulting real-time and core requirements on an AN/UYK-20 standard Navy mini-computer.DOI: 10.1002/j.2161-4296.1981.tb01439.x 被引量: 3 ...
In response to this massive influx of data, the field of Data Science has come to the forefront in the past decade. Cobbled together by people from a diverse array of fields — statistics, physics, computer science, design, and many more — the field of Data Science represents our collectiv...
A systematic quantum-chemical study of the convergence of proton NMR shieldings with the size of solid-state fragments is presented for a host–guest system. The largest system computed at Hartree–Fock and density-functional theory levels comprises a full first shell of complexes surrounding a cen...
In some clinical situations, for which RCT are rare or impossible, the majority of the evidence comes from observational studies, but standard estimations could be biased because they ignore covariates that confound treatment decisions and outcomes. Methods Three observational studies were conducted to ...

The most used GPS devices in soccer vary between 5 and 20 Hz, resulting in an error rate during acceleration, deceleration, and constant motion of approximately 3.1–11.3% and 1.9–6.0%, respectively [26]. Moreover, 1 Hz and 5 Hz GPS devices also show a consistent error when estimating ...
