Establishing the limits between polarity sensitivity, negative polarity and negative concord [PDF]

open access: yesLinguistic Typology
In this paper, by focussing on the behaviour of polarity elements from a variety of languages from different language families (namely, Basque, Hindi, English, Romanian, Spanish, Greek, Czech, and Russian) we investigate the relationship between polarity

A systems biology approach to multi-scale modelling and analysis of planar cell polarity in drosophila melanogaster wing [PDF]

open access: yes, 2013
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Systems biology aims to describe and understand biology at a global scale where biological systems function as a result of complex mechanisms that happen at

The morphological dimension of polarity licensing [PDF]

open access: yes, 2012
Polarity items must, by definition, fit inside the scope of their licenser; items like any N, in addition, appear to require a c-commanding and overt licenser. It is argued that the relevant restriction refers to precedence, not e-command, and that it is

Spectral degree of polarization uniformity for polarization-sensitive OCT [PDF]

open access: yesJournal of Modern Optics, 2014
Depolarization of light can be measured by polarization-sensitive optical coherence tomography (PS-OCT) and has been used to improve tissue discrimination as well as segmentation of pigmented structures. Most approaches to depolarization assessment for PS-OCT - such as the degree of polarization uniformity (DOPU) - rely on measuring the uniformity of ...

Polarity-Sensitive Cell Membrane Probe Reveals Lower Polarity of Tumor Cell Membrane and Its Application for Tumor Diagnosis

open access: yes, 2022
Cancer is a health threat worldwide, and it is urgent to develop more sensitive cancer detection methods. Herein, a polarity-sensitive cell membrane probe (named COP) was developed for detecting cancer cells and tumors sensitively and selectively at the ...

Probing Polarity and pH Sensitivity of Carbon Dots in Escherichia coli through Time-Resolved Fluorescence Analyses

open access: yesNanomaterials, 2023
Intracellular monitoring of pH and polarity is crucial for understanding cellular processes and functions. This study employed pH- and polarity-sensitive nanomaterials such as carbon dots (CDs) for the intracellular sensing of pH, polarity, and viscosity

On the negative polarity sensitive indefinite determiner nakar ‘any’ in Faroese

open access: yesNordlyd: Tromsø University Working Papers on Language & Linguistics, 2009
This paper reports on fieldwork undertaken during the NORMS dialect workshop in the Faroe Islands in August 2008. I present and discuss findings from a questionnaire study of the negative polarity sensitive indefinite determiner nakar ‘any.’ The ...

Effect of acetylene linkage on solvatochromism of betaine consisting of 1-methylpyridinium and phenolate units

open access: yesResults in Chemistry, 2023
Solvatochromic behavior of 4-[2-(1-methylpyridinium-4-yl)ethynyl]phenolate (5) in various solvents was investigated to elucidate the effect of C≡C linkage. 5 was found to exhibit negative solvatochromism, where the observed maximum absorption wavelengths

Cell polarity and PIN protein positioning in Arabidopsis requie STEROL METHYLTRANSFERASE1 function [PDF]

open access: yes, 2003
Plants have many polarized cell types, but relatively little is known about the mechanisms that establish polarity. The orc mutant was identified originally by defects in root patterning, and positional cloning revealed that the affected gene encodes ...

Novel ERP Evidence for Processing Differences Between Negative and Positive Polarity Items in German

open access: yesFrontiers in Psychology, 2019
One unresolved question about polarity sensitivity in theoretical linguistics concerns whether and to what extent negative and positive polarity items are parallel.
