BOOST HARDSKILL WITH CTF COMPETITIONS

2023
The paper considers the principles underlying the CTF competitions, describes the main types of tasks. The authors reviewed the skills and knowledge that students who take part in the CTF receive and improve. It is shown that independent passage of CTF sites and information security competitions gives students not only an understanding of the current ...

Optics of CTFs

2009
Double refraction of light by a bulk material was probably first reported by Erasmus Barfholin (1625-1698), a professor of medicine at the University of Copenhagen. In 1669, he observed that images seen through a mineral named Iceland spar (calcite) were doubled, as shown in Fig. 7.1.

CTF determination and correction in electron cryotomography

Ultramicroscopy, 2006
Electron cryotomography (cryoET) has the potential to elucidate the structure of complex biological specimens at molecular resolution but technical and computational improvements are still needed. This work addresses the determination and correction of the contrast transfer function (CTF) of the electron microscope in cryoET.

Fast, spatially varying CTF correction in TEM

Ultramicroscopy, 2012
We have developed new methods for contrast transfer function (CTF) correction of tilted and/or thick specimens. In order to achieve higher resolutions in cryo-electron tomography (CryoET), it is necessary to account for the defocus gradient on a tilted specimen and possibly the defocus gradient within a thick specimen.
