Nectar and pollination drops: how different are they?
BACKGROUND Pollination drops and nectars (floral nectars) are secretions related to plant reproduction. The pollination drop is the landing site for the majority of gymnosperm pollen, whereas nectar of angiosperm flowers represents a common nutritional resource for a large variety of pollinators. Extrafloral nectars also are known from all vascular plants, although among the gymnosperms they ar...
متن کاملPsych-Predicates: How They Are Different
This paper is concerned with characterizing psych-predicates in Korean and possibly in Japanese in the GL spirit. We focus on the the status of the Experiencer (or ‘judge’) in relation to other arguments and examine the firstperson subjectivity data (constraint). The relevant cause and effect relation and consequent coerced event function is postulated for coherent interpretation.
متن کاملHow Many Different "John Smiths", and Who Are They?
In this work we propose three unsupervised measures to automatically identify the number of distinct entities a given ambiguous name refers to in a corpus. We experiment with 22 artificially created name conflations and observe that the measure (PK2) formulated as the ratio of two successive clustering criterion function values outperforms the other two measures. We also describe a method to as...
متن کاملCell-penetrating peptides and antimicrobial peptides: how different are they?
Some cationic peptides, referred to as CPPs (cell-penetrating peptides), have the ability to translocate across biological membranes in a non-disruptive way and to overcome the impermeable nature of the cell membrane. They have been successfully used for drug delivery into mammalian cells; however, there is no consensus about the mechanism of cellular uptake. Both endocytic and non-endocytic pa...
متن کاملPredicting maternal rat and pup exposures: how different are they?
Risk and safety assessments for early life exposures to environmental chemicals or pharmaceuticals based on cross-species extrapolation would greatly benefit from information on chemical dosimetry in the young. Although relevant toxicity studies involve exposures during multiple life stages, the mother's exposure dose is frequently used for extrapolation of rodent toxicity findings to humans an...
