Comparative phytochemical and morphological analyses of three Italian Primula species
No full textThe taxonomy of alpine Primula species has long been in dispute because of high morphologic variability and several hybridisations. In Primula species, the trichome height and the colour of hair-tips are usually indicated as diacritic characters, but in our experience this is not adequate. The present study, focused on Primula auricula, Primula daonensis and Primula hirsuta, therefore proposes the use of other morphologic trichome parameters (size and dimensional ratio of stalk, neck and gland head). Phytochemical investigations about the flavonoid composition (epicuticular and vacuolar) of leaves, as taxonomic markers, have also been performed. We report the isolation and identification of two new flavonol glycosides, isorhamnetin 3-O-(2,6-di-O-β-D-glucopyranosyl-β-D-glucopyranoside) (1) and kaempferol 3-O-(2-O-α-L-rhamnopyranosyl-6-O-β-D-xylopyranosyl-β-D-glucopyranoside) (2) and of eight known flavonoids. Size and dimensional ratio of the three trichome elements (stalk, neck and glandular head) are typical for each species analysed. The flavonoid profile well characterise the entities under study. Three different profiles have been obtained with both vacuolar and epicuticular flavonoids. The morphologic and phytochemical markers proposed in this work seem to be parameters which significatively discriminate the species under stud
Papiri(an)us, Paperinus, Papirinus e l’ 'Orthographia' di Giovanni Tortelli
No full textThis paper aims at examining afresh some fragments handed down in the Orthographia of Giovanni Tortelli (about 1400-1466) and attributed by Tortelli to Papirianus, a Latin grammarian whose name, dates, work are poorly documented. The humanist was accused of being a forger by the eminent philologists Keil and Sabbadini because most of these fragments are also found in the works of Priscianus and Marius Victorinus. The study of the sources reveals nonetheless that some of them are original and authentic; the thought of Papirianus is, moreover, rather close to that found in treatises on orthography from the first and second centuries AD. The Appendix proposes hypotheses for Papiri(an)us, Papirinus, Paperinus, names that can all be attributed to the same person, the author of an Orthographia and an Analogia. The Appendix also gathers together all the texts transmitted in the Orthographia by Giovanni Tortelli under the name of "Papirianus Grammaticus"
Soft biometrics and their application in person recognition at a distance
No full textSoft biometric information extracted from a human body (e.g., height, gender, skin color, hair color, and so on) is ancillary information easily distinguished at a distance but it is not fully distinctive by itself in recognition tasks. However, this soft information can be explicitly fused with biometric recognition systems to improve the overall recognition when confronting high variability conditions. One significant example is visual surveillance, where face images are usually captured in poor quality conditions with high variability and automatic face recognition systems do not work properly. In this scenario, the soft biometric information can provide very valuable information for person recognition. This paper presents an experimental study of the benefits of soft biometric labels as ancillary information based on the description of human physical features to improve challenging person recognition scenarios at a distance. In addition, we analyze the available soft biometric information in scenarios of varying distance between camera and subject. Experimental results based on the Southampton multibiometric tunnel database show that the use of soft biometric traits is able to improve the performance of face recognition based on sparse representation on real and ideal scenarios by adaptive fusion rules

Edwin Berry, resident of Adelino, conducted and celebrated the stations of the cross pageant as worshippers ascended up the Tome Hill to the site of the three crosses. The tradition originally started as a passion play in Tome plaza in 1948 and later evolved into a procession and ascent to Tome Hill.
