The article a(n) in English quantifying expressions: A default marker of cardinality
2020
Certain English quantificational expressions feature what appears to be an indefinite article, e.g. 'a bunch, a few, a hundred'. These can be divided into three types of quantifying expressions: pseudopartitives ('a lot, a bunch, a ton'), article-requiring quantifiers ('a few, a couple, a hundred'), and article-free quantifiers ('three, many, several'); article-free quantifiers have an article under certain circumstances, e.g. modification by an adjective ('a surprising 30 …'). While standard analyses would take the article in these expressions to be a D head, it is argued here that the article is not in D, nor is it singular or count, as evidenced by its (lack of an) interaction with verba…
Characterization of a CZT focal plane small prototype for hard X-ray telescope
2005
The promise of good energy and spatial resolution coupled with high efficiency and room temperature operation has fuelled a large international effort to develop cadmium zinc telluride (CZT) for hard X-ray applications. We are involved on the development of a hard X-ray telescope based on multilayer optics and focal plane detector operative in the 10-80 keV energy range. This telescope requires a high efficiency focal plane providing both fine spatial resolution and spectroscopy with a compact and robust design. This paper reports preliminary results on the characterization both in spectroscopic and spatial response of two small pixellated CZT detectors (10times10times1 mm3 and 10times10tim…
