Functional magnetic resonance imaging (fMRI) has been recently proposed for the evaluation of the esophagus. Our aim is to assess the role of fMRI as a technique to assess morphological and functional parameters of the esophagus in patients with esophageal motor disorders and in healthy controls. Subsequently, we assessed the diagnostic efficiency of fMRI in comparison to videofluoroscopic and ...
Faltering demand and performance of the logistics service sector in two cities of South-East Finland
Emerging markets experienced strong growth since the years 2002–2003, and this was especially the case for import markets in Russia. Many border-sharing countries, as well as nearby sea ports, terminal areas and logistics service companies, benefited from it and revenue growth was the norm for years. This was also the case in Finland, more specifically for South-East cities such as Kotka and Ko...
I present a language for specifying planning problems in which there are external events, that is, events beyond the direct control of the planner which may happen while a plan is being executed. The language is based on Miller and Shanahan’s representation of narratives in the situation calculus. I describe an implemented planner that produces correct plans for this language, and discuss how s...
Projection in the situation calculus refers to answering queries about the future evolutions of the modeled domain, while progression refers to updating the logical representation of the initial state so that it reflects the changes due to an executed action. In the general case projection is not decidable and progression may require second-order logic. In this paper we focus on a recent result...
History has demonstrated during the 20 century that industrial development carries hazards that should not be ignored because they endanger humans, the environment and production facilities. For this reason, continuous development of new production technologies should be accompanied by a comparable development in industrial safety technologies. Safety-critical applications in complex processes ...
NASA’s Kepler mission has provided several thousand transiting planet candidates during the four years of its nominal mission, yet only a small subset of these candidates have been confirmed as true planets. Therefore, the most fundamental question about these candidates is the fraction of bona fide planets. Estimating the rate of false positives of the overall Kepler sample is necessary to der...
Stem cells: attributes, cycles, spirals, pitfalls and uncertainties. Lessons for and from the crypt.
We consider some of the problems involved in current discussions on stem cells in adult mammalian tissues. The present concepts involve a number of pitfalls, weaknesses and logical, semantic and classification problems. This indicates the necessity for new and well-defined concepts that are amenable to experimental analysis. One of the major difficulties in considering stem cells is that they a...
