Molecular screening tools to study Arabidopsis transcription factors

Frontiers in Plant Science, 2011
In the model plant Arabidopsis thaliana, more than 2000 genes are estimated to encode transcription factors (TFs), which clearly emphasizes the importance of transcriptional control. Although genomic approaches have generated large TF Open Reading Frame (

Rod Laser – The first laser was a rod laser [PDF]

Laser Technik Journal, 2005
Laser technology is relatively young. The first laser was built in 1960 by Maiman at AT&T Labs in the USA. It was a rod-shaped ruby laser, this arrangement having been chosen for its favourable symmetry (Fig. 1). Starting from this device, the technology of solid-state lasers developed rapidly.

Appraising the holistic value of Lenvatinib for radio-iodine refractory differentiated thyroid cancer: A multi-country study applying pragmatic MCDA

BMC Cancer, 2017
Background The objective of the study was to reveal through pragmatic MCDA (EVIDEM) the contribution of a broad range of criteria to the value of the orphan drug lenvatinib for radioiodine refractory differentiated thyroid cancer (RR-DTC) in country ...

Keyhole threshold and morphology in laser melting revealed by ultrahigh-speed x-ray imaging

Science, 2019
The key to keyhole formation The formation of keyholes, or vapor-filled depressions, during laser welding presents a large problem for additive manufacturing. Cunningham et al. used high-speed x-ray imaging to take a detailed look at keyhole formation in

Petawatt Laser Guiding and Electron Beam Acceleration to 8 GeV in a Laser-Heated Capillary Discharge Waveguide.

Physical Review Letters, 2019
Guiding of relativistically intense laser pulses with peak power of 0.85 PW over 15 diffraction lengths was demonstrated by increasing the focusing strength of a capillary discharge waveguide using laser inverse bremsstrahlung heating.
