The paper considers broadcasting in radio networks, modeled as unit disk graphs (UDG). Network stations are modeled as points in the Euclidean plane, where a station is connected to all stations at distance at most 1 from it. A message transmitted by a station reaches all its neighbors, but a station hears a message (receives the message correctly) only if exactly one of its neighbors transmits...

The structure of the Al70Pd21Mn9 surface has been investigated using high-resolution scanning tunneling microscopy. From two large fivefold terraces on the surface in a short decorated Fibonacci sequence, atomically resolved surface images have been obtained. One of these terraces carries a rare local configuration in the form of a ring. The location of the corresponding sequence of termination...

Pain assessment in fish is particularly challenging due to their evolutionary distance from humans, their lack of audible vocalization, and apparently expressionless demeanour. However, there are criteria that can be used to gauge whether pain perception occurs using carefully executed scientific approaches. Here, the standards for pain in fish are discussed and can be considered in three ways:...

Solid oxide fuel cells (SOFCs) are a major candidate technology for clean energy conversion because of their high efficiency and fuel flexibility. The development of intermediate-temperature (500–750 8C) SOFCs requires electrolytes with high oxide ion conductivity (exceeding 10 2 Scm 1 assuming an electrolyte thickness of 15 mm). This conductivity, in turn, necessitates enhanced understanding o...

The elucidation of the local atomic structure of a pseudomorphic film of Cu deposited on the five-fold surface of i-Al70Pd21Mn9using medium-energy ion scattering spectroscopy is reported. Monte Carlo calculations, using the VEGAS code, have been utilized to simulate the blocking of 100 keV He+ ions scattered from the overlayer. The coordinates of the Cu atoms in the overlayer derived from this ...

The effectiveness and efficiency of the screening programme for congenital hypothyroidism in the Mersey region from 1983 to 1989was examined byan analysis oflaboratory, manual and computerised district records, case notes, and Hospital Activity Analysis data. Births from 1 January 1983 to 31 December 1989 formed the study cohort and the proportion of live births screened, age when treatment was...

We present a comprehensive study of Bi thin-film growth on quasicrystal surfaces. The substrates used for the growth are the fivefold surface of icosahedral (i)-Al-Cu-Fe and i-Al-Pd-Mn and the tenfold surface of decagonal (d)-Al-Ni-Co quasicrystals. The growth is investigated at 300 and 525 K substrate temperatures and at different coverage (θ) ranging from submonolayer to ten monolayers. The f...

This editorial gives an overview of the different roots and forms of discrimination and stigmatisation towards people with mental illness. It explains the differences between stereotype, prejudice and discrimination. It further highlights some research foci of stigma research in the last decade. The emphasis was mostly on investigating the attitudes of the general population, but barely address...
