MOTIVATION Predicting the part of speech (POS) tag of an unknown word in a sentence is a significant challenge. This is particularly difficult in biomedicine, where POS tags serve as an input to training sophisticated literature summarization techniques, such as those based on Hidden Markov Models (HMM). Different approaches have been taken to deal with the POS tagger challenge, but with one ex...

A good POS tagger is a critical component of a machine translation system and other related NLP applications where an appropriate POS tag will be assigned to individual words in a collection of texts. There is not enough POS tagged corpus available in Manipuri language ruling out machine learning approaches for a POS tagger in the language. A morphology driven Manipuri POS tagger that uses thre...

This paper examines unsupervised approaches to part-of-speech (POS) tagging for morphologically-rich, resource-scarce languages, with an emphasis on Goldwater and Griffiths’s (2007) fully-Bayesian approach originally developed for English POS tagging. We argue that existing unsupervised POS taggers unrealistically assume as input a perfect POS lexicon, and consequently, we propose a weakly supe...

Neuro-imaging studies on reading different parts of speech (PoS) report somewhat mixed results, yet some of them indicate different activations with different PoS. This paper addresses the difficulty of using fMRI to discriminate between linguistic tokens in reading of running text because of low temporal resolution. We show that once we solve this problem, fMRI data contains a signal of PoS di...

Most previous studies examining physical activity in Public Open Spaces (POS) focused solely on the physical environment. However, according to socio-ecological models the social environment is important as well. The aim of this study was to determine which social and physical environmental factors affect adolescents' visitation and physical activity in POS in low-income neighbourhoods. Since c...

PURPOSE Progressive accumulation of extracellular material at the basolateral side of the retinal pigment epithelium (RPE) is a key event in the pathogenesis of age-related macular degeneration (AMD). The authors previously demonstrated that modifications with lipid peroxidation products, such as 4-hydroxynonenal (HNE) and malondialdehyde (MDA), stabilize photoreceptor outer segment (POS) prote...

Pectic-Oligosaccharides (POS) have a growing potential in food and feed industries. To satisfy the demand of worldwide markets from POS and avoid the shortcomings of currently applied methodologies encountered in their preparation, the present study highlights a novel robust approach for POS biosynthesis. In the current approach, Aspergillus sp.section Flavi strain EGY1 DSM 101520 was grown on ...

Introduction The retinal pigment epithelium (RPE) forms the outermost layer of the retina and consists of simple, cuboidal epithelial cells with unique plasma membrane polarity (Marmorstein, 2001). In the mammalian retina, each RPE cell underlies ~30 photoreceptor neurons all of which shed the aged, distal tip of their outer segment every morning stimulated by light and circadian rhythms (Young...

A broth microdilution method was used to evaluate the in vitro activities of seven antifungal agents against 15 clinical strains of Rhizopus microsporus. Amphotericin B (AMB) and posaconazole (POS) were the most active drugs. In a model of disseminated R. microsporus infection in immunosuppressed mice, we studied the efficacy of POS administered once or twice daily against four of the strains p...
