Vision-aided Monitoring and Control of Thermal Spray, Spray Forming, and Welding Processes [PDF]

open access: yes, 1993
Vision is one of the most powerful forms of non-contact sensing for monitoring and control of manufacturing processes. However, processes involving an arc plasma or flame such as welding or thermal spraying pose particularly challenging problems to ...

Enhanced deoxyviolacein bioproduction via enzyme condensation with a yeast glycolytic enzyme‐derived peptide tag

open access: yesBiotechnology Progress, EarlyView.
Fusion of a 27‐amino‐acid peptide tag derived from a glycolytic enzyme enabled artificial assembly formation of the two violacein biosynthetic enzymes, VioE and VioC. This assembly resulted in enhanced biosynthesis of deoxyviolacein. Abstract In microbial production, regulating endogenous and exogenous synthetic pathways is essential.

Dynamic MR-Imaging with Radial Scanning, a Post-Acquisition Keyhole Approach

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
A new method for 2D/3D dynamic MR-Imaging with radial scanning is proposed. It exploits the inherent strong oversampling in the centre of -space, which holds crucial temporal information of the contrast evolution.

Influence of Surface State in Micro-Welding of Copper by Nd:YAG Laser

open access: yesApplied Sciences, 2018
Laser welding of copper is characterized by low and unstable light absorption around 1000 nm wavelength. Combination of high thermal conductivity and low melting point makes it difficult to obtain good welding quality and leads to low energy utilization.

Evolutionary patterns and structural divergence of CENH3 in legumes: Implications for haploid induction breeding

open access: yesGrassland Research, EarlyView.
From structure to application: evolutionary insights and genome editing strategies for CENH3‐mediated haploid induction in legumes. Abstract Background The centromeric histone variant CENH3 is crucial for chromosome segregation and haploid induction in plants, yet its evolutionary patterns in legumes remain poorly characterized. Methods We investigated
