Fingernails structure are rich in orientation, ridges and edge features. Inspired by Edge Histogram Descriptor (EHD), this paper presents an efficient orientation-based local descriptor, named histogram of orientation delineate (HROD). HROD is based on the fact that human vision sensitive to features for image perception. For a given image, algorithm first execute perform pre-process i.e., re-s...

Fingernail has been suggested as a biomarker of fluoride (F) body burden, but there is no consensus if it would be a reliable indicator of F exposure from dentifrice. Therefore, the present study was conducted to investigate if fingernails would have sensitivity to detect F exposure from dentifrice in young children. Twenty-three 1-3-year-old children living in the city of Piracicaba (0.72 ppm ...

Helicobacter pylori infection remains one of the most common in humans, but the route of transmission of the bacterium is still uncertain. This study was designed to elucidate possible sources of infection in an isolated, rural population in Guatemala. A total of 242 subjects in family units participated in the study. A medical history, including a history of dyspepsia, was taken by a physician...

Abstract The possibility of establishing a novel technique for reliably accessing glycemic information in non-invasive, easy to implement method at THz frequencies via the fingernail bed is investigated. nail bed’s major content blood its various glucose levels and also partially protected from environmental conditions by plate, making it desirable platform non-invasive sensing. study based on ...

Complementary Metal-Oxide-Semiconductor Imager In article number 2206699, Qing Yang, Fenni Zhang, Di Wang, and co-workers transform a complementary metal-oxide-semiconductor imager into compact multimodal sensing platform (M-imager) via dual-focus imaging strategy. A fingernail-sized M-imager can simultaneously detect the information involved in host locating of mosquitoes, i.e. visual informat...
