An optical imaging system generally consists of an illumination source and a light detection unit. For conventional imaging techniques, a scene is illuminated by a uniform light field and detected ...

Students from Sydney Grammar School recreated the drug Daraprim ®, also referred to as pyrimethamine. This news was extensively reported † in December 2016. The students produced the drug by following ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

The H ii region distribution of M33, published by Boulesteix et al. (1974, A&A, 37, 33), is analyzed using a 2D Fourier-transform technique. We show that the two-armed structure extends to r≈28'.

In this paper we describe a method for computing the Discrete Fourier Transform (DFT) of a sequence of $n$ elements over a finite field $\mathrm{GF}(p^m)$ with a ...

Nuclear magnetic resonance (NMR) spectroscopy was developed to detect protons, and has since then been applied in studying the molecular structure of proteins, RNA, DNA complexes, and interactions ...

Bruker's NMR software TopSpin™ combines various new features to explore the world of NMR at-ease, making the Fourier 300 an ideal system for chemical education and industrial routine analysis. It ...
