Flavodoxins, which exist widely in microorganisms, have been found in various pathways with multiple physiological functions. The flavodoxin (Fld) containing the cofactor flavin mononucleotide (FMN) from sulfur-reducing bacteria Desulfovibrio gigas (D. gigas) is a short-chain enzyme that comprises 146 residues with a molecular mass of 15 kDa and plays important roles in the electron-transfer c...

A class of image-matrix-based feature extraction algorithms has been discussed earlier. The correspondence argues that 2-D principal component analysis and Fisher linear discriminant (FLD) are equivalent to block-based PCA and FLD. In this correspondence, we point out that this statement is not rigorous.

In this contribution we go through the developments that in the years from 1968 to about 1974 led from the Veneziano model to the bosonic string theory. They include the construction of the N -point amplitude for scalar particles, its factorization through the introduction of an infinite number of oscillators and the proof that the physical subspace was a positive-definite Hilbert space. We als...

This paper presents a new algorithm for feature generation, which is approximately derived based on geometrical interpretation of the Fisher linear discriminant analysis. In a field of pattern recognition or signal processing, the principal component analysis (PCA) is often used for data compression and feature extraction. Furthermore, iterative learning algorithms for obtaining eigenvectors ha...

BACKGROUND Several studies have evaluated accuracy of intraoral scanners (IOS), but data is lacking regarding variations between IOS systems in the depiction of the critical finish line and the finish line accuracy. The aim of this study was to analyze the level of finish line distinctness (FLD), and finish line accuracy (FLA), in 7 intraoral scanners (IOS) and one conventional impression (IMPR...

KEYWORD: bisphenol A; immune-affinity column; high-performance liquid chromatography ABSTRACT: A rapid and sensitive method using immuno-affinity columns (IACs) as sample purification procedure and high-performance liquid chromatography (HPLC) tandem fluorescence detector (FLD) for detection has been developed for the determination of bisphenol A (BPA) in beer. The limit of detection (LOD) is 0...

The deadline assignment problem arises in distributed systems where each subtask composing a distributed task must receive a local deadline such that the task end-to-end deadline is met. It also arises in multi-hop networks where the maximum sojourn time of a flow on each visited node must be bounded by a local deadline that allows the flow end-to-end deadline to be met. We first formalize the ...

Nursing staff that work with patients with frontal lobe dementia (FLD) experience challenges that may lead to physical and psychiatric distress. The aim of this study was to capture the feelings, experiences, and reflections of the health staff regarding interactions with and caring for patients with FLD and to highlight what it means for health staff to care for patients with FLD through their...
