Scalar properties of negative polarity superlatives

open access: yesBorealis: An International Journal of Hispanic Linguistics, 2020
Most theories agree that polarity sensitivity must be related to scalarity one way or another. Superlatives are a good example of this, since their “endpoint nature” allows for them to be in negative contexts with a quantitative interpretation.

The polarization sensitivity of GRETINA

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2022
Compton polarimeters have played an important role in the study of nuclear structure physics, but have often been limited in their applications because of relatively low γ-ray detection efficiency. With the advent of γ-ray tracking detector arrays, which feature nearly 4π solid angle coverage and the ability to identify the location of Compton ...

Cell Polarity and Morphogenesis: Functions and Mechanisms of Cell Divisions in Vertebrate Gastrulation [PDF]

open access: yes, 2004
Gastrulation shapes a vertebrate embryo from an egg-shaped aggregate of cells. In many vertebrates, massive cell divisions occur during gastrulation. In this thesis, I investigate the pattern, function, and regulation of mitotic divisions in zebrafish ...

Space charge dynamics in oil and thick pressboard combined system under polarity reversal voltage [PDF]

open access: yes, 2014
In this study, the space charge dynamics in an oil and oil impregnated pressboard combined insulation system are investigated by the means of pulsed electroacoustic (PEA) technique under voltage polarity reversal conditions. To be closer to the real case

On the true nature of ÇOKTAN in Turkish

open access: yesDilbilim Araştırmaları Dergisi
Turkish has the temporal adverb çoktan ‘long time ago’ that has been treated as a positive polarity item (PPI) in recent studies. It has been argued that it cannot co-occur with clause-mate negation, whereas native speakers seem to have split it into two
