The purpose of this note is to demonstrate that a weak form of club guessing on ω1 implies the existence of an Aronszajn line with no Countryman suborders. An immediate consequence is that the existence of a five element basis for the uncountable linear orders does not follow from the forcing axiom for ω-proper forcings.

While there are extensive theoretical studies on firms’ responses to environmental regulations and enforcement, there are few empirical analyses of firms’ expenditures on pollution abatement in responding to different regulations and enforcement strategies. This paper presents an empirical analysis of pollution abatement efforts of Chinese industrial firms under a combination of pollution charg...

Superstorm Sandy affected much of the US East Coast extending over 1800 km. It passed over the test location in the State of Maryland on 29 October 2012. Being 350 km away from the regions of highest intensity the storm was of lower intensity at the test location. Continuous radon monitors and passive radon monitors were used for the measurement. The test location was the basement of a single f...

A discussion of several exotic models and how well they are able to describe the data, with particular emphasis on atmospheric neutrinos.

One of the challenges that plasma research encounters is how to generate a large-scale plasma plume at atmospheric pressure. Through utilizing a third electrode biased by a direct-current voltage, a longer plasma plume is generated by a plasma jet in dielectric barrier discharge configurations. Results indicate that the plume length increases until it reaches the third electrode with increasing...
