The Varchenko determinant of a Coxeter arrangement
(De Gruyter, 2018)
The Varchenko determinant is the determinant of a matrix defined from an arrangement of hyperplanes. Varchenko proved that this determinant has a beautiful factorization. It is, however, not possible to use this factorization ...
Head-to-nerve analysis of electromechanical impairments of diffuse axonal injury
(Springer, 2018-11-14)
The aim was to investigate mechanical and functional failure of diffuse axonal injury (DAI) in nerve bundles following frontal head impacts, by finite element simulations. Anatomical changes following traumatic brain injury ...
Characterization of an amplified piezoelectric actuator for multiple reference optical coherence tomography
(Optica, 2018-08-30)
The characterization of an amplified piezoelectric actuator (APA) as a new axial scanning method for multiple-reference optical coherence tomography (MR-OCT) is described. MR-OCT is a compact optical imaging device based ...
Optimizing fluorescent protein expression for quantitative fluorescence microscopy and spectroscopy using herpes simplex thymidine kinase promoter sequences
(Wiley, 2018-04-16)
The modulation of expression levels of fluorescent fusion proteins (FFPs) is central for recombinant DNA technologies in modern biology as overexpression of proteins contributes to artifacts in biological experiments. In ...
Lewis acid promoted anomerisation of alkyl O- and S-xylo-, arabino- and fucopyranosides
(Elsevier, 2018-11-24)
Pentopyranoside and 6-deoxyhexopyranosides, such as those from d-xylose, l-arabinose and l-fucose are components of natural products, oligosaccharides or polysaccharides. Lewis acid promoted anomerisation of some of their ...
