STUDY OBJECTIVES To locate geographical sources of engine exhaust emissions in Great Britain and to link them with the birth addresses of children dying from cancer. To estimate the cancer initiating roles of nearby roads and railways and to measure effective ranges. DESIGN Birth and death addresses of all children born between 1955 and 1980 in Great Britain, and dying from leukaemia or other...

When the railway appeared as a new means of transportation in the first half of the 19th century, its top speed of 30 to 40 km/h was considered dangerous. In Germany, where Adler transported two barrels of beer between Nuremberg and Fürth in 1835 as the first German rail freight, physicians warned people against such perilous adventures and farmers were worried that their cows grazing alongside...

We prove a Banach version of Garland's method proving vanishing cohomology for groups acting on simplicial complexes. The novelty this new is that our condition applies to every reflexive space. This allows us deduce several criteria group with coefficients in classes spaces (uniformly curved spaces, Hilbertian and $L^p$ spaces). Using these criteria, we improve recent results regarding fixed p...

GSM-Railways (GSM-R) is an obsolete mobile technology with a number of shortcomings in terms of capacity and capability. These shortcomings become a major issue for railways as GSM-R may limit the number of running trains in some areas and it cannot support advanced data services. Hence, alternative technologies, such as LTE, have to be considered as a future railway communication technology. T...

The Alternating Brightness Star (ABS) is an illusion that provides insight into the relationship between brightness perception and corner angle. Recent psychophysical studies of this illusion have shown that corner salience varies parametrically with corner angle, with sharp angles leading to strong illusory percepts and shallow angles leading to weak percepts. It is hypothesized that the illus...

This paper reports the three-dimensional (3D) generalization of our previous 2D higher-order matched interface and boundary (MIB) method for solving elliptic equations with discontinuous coefficients and non-smooth interfaces. New MIB algorithms that make use of two sets of interface jump conditions are proposed to remove the critical acute angle constraint of our earlier MIB scheme for treatin...

Part of the Hang-Tai High-speed Railway (Hangzhou via Shaoxing to Taizhou in Zhejiang Provence) China passes through diatomaceous earth area, which is first time history Chinese high-speed railway construction. This type soil has significant compressibility, swelling and disintegration. Diatomaceous also shows a sharp reduction strength when exposed water, severely impacts safety project. Howev...
