High−resolution hyperspectral imaging (HSI) provides an abundance of spectral data for feature analysis in image processing. Usually, the amount of information contained in hyperspectral images is excessive and redundant, and data mining for waveband selection is needed. In applications such as fruit and vegetable defect inspections, effective spectral combination and data fusing methods are re...

This study describes the determination of polycyclic aromatic hydrocarbons (PAHs) in water using high-performance liquid chromatography (HPLC) coupled with fluorescence detection (FLD). Because individual PAHs are generally present in water only at trace levels, a sensitive and accurate determination technique is essential. The separation and detection of five PAHs were run completely within 25...

PURPOSE Fatty liver disease (FLD) is an increasing prevalent disease that can be reversed if detected early. Ultrasound is the safest and ubiquitous method for identifying FLD. Since expert sonographers are required to accurately interpret the liver ultrasound images, lack of the same will result in interobserver variability. For more objective interpretation, high accuracy, and quick second op...

BACKGROUND/AIMS Frontal lobe dementia (FLD) and primary nonfluent progressive aphasia (PnPA) are two forms of frontotemporal lobe degeneration. The relationship between these conditions remains unclear. Our study aimed to better define the behavioral and cognitive clusters characterizing PnPA patients. METHODS We cognitively and behaviorally evaluated three groups of newly diagnosed patients ...

Recent studies have reported inconsistent results on the association between sleep duration and the risk of fatty liver disease (FLD). Thus, we quantitatively evaluated this association by performing a systematic review and meta-analysis, based on a comprehensive electronic search in databases of PubMed, Web of Science, EMBASE, ClinicalTrials.gov, Wanfangdata and Chinese National Knowledge Infr...

somatic embryos of persian walnut were transformed with two strains of agrobacterium tumefaciens i.e. lba4404 and c58, and two plasmids, namely, pbi121 with nptii and gus genes for improving the transformation protocol, and p6u-ubi-fvti plasmid containing the hpt and fld genes. the transformation frequency was 10%. pcr and rt-pcr analysis proved the presence and expression of the genes. the tra...

We provide a non-asymptotic analysis of the generalisation error of compressive Fisher linear discriminant (FLD) classification that is dimension free under mild assumptions. Our analysis includes the effects that random projection has on classification performance under covariance model misspecification, as well as various good and bad effects of random projections that contribute to the overa...

the forming limit diagram (fld) is a useful method for characterizing the formability of sheet metals. in this paper, different numerical models were used to investigate the fld of tailor welded blank (twb). twbs were co2 laser-welded samples of interstitial-free (if) steel sheets with different thicknesses. the results of the numerical models were compared with the experimental fld as well as ...
