Dermatitis artefacta is a disease that occurs as a result of a self-inflicted injury to the skin. The problem quite often is undiagnosed for a long time until the clinical look of bizarre skin lesions combined with non-specific histology and normal blood tests lead to the final identification. This report presents the case of a 62-year-old man who was diagnosed after 10 years of duration of dis...

In the paper some considerations about dynamic measurement scenarios aspects are discussed. The Dynamic Measurement Scenarios are used for creating and managing job workflow in the Virtual Laboratory system. It facilitate defining and monitoring measurement process which quite often consists of many tasks connected between themselves.

Until quite recently, theories on thermophoresis of particles predicted very low thermophoretic velocities of metal particles in liquids. This prediction was based on the understanding that the very high thermal conductivities of metals relative to most liquid media resulted in quite low temperature gradients across the metal particle thereby leading to low net force on the particle. In this pa...

During the past decade, the availability of simple, effective methods for laser cooling and trapping has enabled enormous advances in the experimental study of atoms in their ground state. Until quite recently, however, these techniques have had much less impact on investigations of highly excited atoms and almost none on plasmas. Several laboratories have now begun experiments in which atoms a...

For a discussion about user interfaces for small screens, so-called baby faces, it might be interesting to start with considering another type of “baby faces” – namely, real ones. Until quite recently, human children were perceived as being basically smaller versions of adults, who were just waiting to become strong and educated enough to take their productive place in the grown-ups’ society. B...

Until quite recently, it was taken for granted in AI-and cognitive science more broadlythat activity resulted from the creation and execution of plans. In 1985, several researchers, including myself, independently realized that plans and planning are not necessary-or necessarily useful-in activity. Since this time, a number of alternatives have been proposed. In this issue of AI Magazine, Matth...

The number of diagnostic and therapeutic interventions performed under sedation is growing rapidly. While providing patients with an improved experience secondary to anxiolysis, analgesia, and amnesia, sedation also puts them at risk for associated cardiorespiratory and other complications. Several medications are available for sedation, all of which have unique advantages and disadvantages. Th...

We prove that any ordered field can be extended to one for which every decreasing sequence of bounded closed intervals, of any length, has a nonempty intersection; equivalently, there are no Dedekind cuts with equal cofinality from both sides. Here we strengthes the results from the published version.

Partial types for the λ-calculus were introduced by Thatte in 1988 [8] as a means of typing objects that are not typable with simple types, such as heterogeneous lists and persistent data. In that paper he showed that type inference for partial types was semidecidable. Decidability remained open until quite recently, when O’Keefe and Wand [5] gave an exponential time algorithm for type inferenc...

Mining structures are among the most complex economic systems in prehistory. Until recently, research into prehistoric production processes has strongly focused on technological reconstruction. The complexity of production processes, their interconnectedness with the surrounding socioeconomic network and issues of quantification have, quite regrettably, been addressed to a much lesser extent. S...
