Predicting the future is not easy. As young medical graduates in the 1970s we were told not to bother with infectious disease specialties as they had largely been fi xed with vaccines and antibiotics. There was a surplus of doctors, and the Alma Ata Declaration had ushered in a new model of primary health care which was going to solve third world poverty and disease. Things were looking so good...

The nationwide screening service for breast cancer, known as BOB from the initials of the Dutch title (Bevolkingonderzoek op Borstkanker) has been set up by the Dutch government for asymptomatic women between 50 and 75 years of age. The primary test offered is X-ray mammography, aimed at early detection of breast cancer in order to reduce the mortality from this disease. The examinations are pe...

We present global and local algorithms for evaluating minimal xed points of dependency graphs, a general problem in xed-point computation and model checking. Our algorithms run in linear-time, matching the complexity of the best existing algorithms for similar problems, and are simple to understand. The main novelty of our global algorithm is that it does not use the counter and \reverse list" ...

The article presents the results of study materials obtained during excavations early Turkic enclosure at Chichke-I site. Th is multi-temporal archaeological complex, located 13 km southwest Kurai village Kosh-Agach district Altai Republic, studied in 1982–1983 by Ongudai detachment expedition State University. Enclosure 159, northeastern part site, was one objects. During it found out that bas...

The breakdown point behavior of M-estimators in linear models with xed designs, arising from planned experiments or qualitative factors, is characterized. Particularly, this behavior at xed designs is quite diierent from that at designs which can be corrupted by outliers|the situation prevailing in the literature. For xed designs, the breakdown points of robust M-estimators (those with bounded ...

background: the fi nal position of the abutment changes with the amount of tightening torque. this could eventually lead to loss of passivity and marginal misfi t of prostheses. the aim of this study was to evaluate the effect of three different tightening torques on the marginal adaptation of 3-unit cement-retained implant-supported fi xed dental prostheses (fdps). materials and methods: two i...

Macbeath gave a formula for the number of xed points for each non-identity element of a cyclic group of automorphisms of a compact Riemann surface in terms of the universal covering transformation group of the cyclic group. We observe that this formula generalizes to determine the xed-point set of each non-identity element of a cyclic group of automorphisms acting on a closed non-orientable sur...

In this paper we formulate and prove some xed and common xed pointTheorems for self-mappings dened on complete lower Transversal functionalprobabilistic spaces.

In this paper a hybrid type theory HTT is deened which combines the programming language notion of partial type with the logical notion of total type into a single theory. A new partial type constructor A is added to the type theory: objects in A may diverge, but if they converge, they must be members of A. A xed point typing rule is given to allow for typing of xed points. The underlying theor...

The basics of a block oriented fractal image coder, are described. The output of the coder is an IFS (Iterated Function System) code, which describes the image as a xed-point of a contractive transformation. A new hierarchical interpretation of the IFS code, which relates diierent scales of the xed-point to the code, is presented and proved. The proof is based on nding a function of a continuou...
