Paying invoices sounds simple enough. A vendor creates an invoice and sends a bill, your team approves it, and the money goes out. In practice, though, invoice payments are where a lot of finance ...

A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening the door to atom-specific analysis and control. (Nanowerk Spotlight) ...

Taking both the hub and any spoke will count as an 18.3xx class for math majors, similar to 18.330, and as 16.90 for course-16 majors. Instructor: Prof. Steven G. Johnson. Lectures: MWF10 in 2-142 ...

Abstract: This article introduces a novel variational formula for modeling waveguides with uniformly curved longitudinal axes. Using the Rayleigh-Ritz method, we analyze the electromagnetic fields in ...

Microscope images could be obtained much more quickly -- rather than one pixel at a time -- thanks to a new imaging method for neutral atomic beam microscopes. It could ultimately lead to engineers ...
