Many papers in the medical literature analyze the cost-effectiveness of screening for diseases by comparing a limited number of a priori testing policies under estimated problem parameters. However, this may be insufficient to determine the best timing of the tests or incorporate changes over time. In this paper, we develop and solve a Markov Decision Process (MDP) model for a simple class of a...

An irregular assignment is a k -labeling of the edges : {1, 2, , } f E k → ... such that the vertex weights (label sums of edges incident with the vertex) are different for all vertices of G . The smallest k for which there is an irregular assignment is the irregularity strength. The notion of irregularity strength was introduced by Chartrand et al. [8] and studied by numerous authors, see [6,1...

The Occasional Papers series is intended to provide a forum for examining a wide range of topics of interest to the hemophilia community. The World Federation of Hemophilia does not engage in the practice of medicine and under no circumstances recommends particular treatment for specific individuals. Dose schedules and other treatment regimes are continually revised and new side effects recogni...

HAAS and HILL [1925, 1] have recently directed attention to a chromogen of considerable interest which escapes from the plasmolysed cells of Mercurialis perennis. If the coarsely divided tissue be steeped, anaerobically, in chloroform water for a short time, there results an extract which, on exposure to oxygen, assumes first a rich blue and then a yellow-brown colour. These investigators [1925...

‎‎we investigate graham higman's paper emph{enumerating }$p$emph{-groups}‎, ‎ii‎, ‎in which he formulated his famous porc conjecture‎. ‎we are able to simplify some of the theory‎. ‎in particular‎, ‎higman's paper contains five pages of homological algebra which he uses in‎ ‎his proof that the number of solutions in a finite field to a finite set of‎ ‎emph{monomial} equations is porc‎. ‎it turn...

a simple, rapid new technique is described for the electrophoresis of hemo­globin when screening large human populations. the method uses a drop of finger tip's blood dried on a thick filter paper as the specimen. the simplicity of the sampling, tagging, transportation and electrophoresis, provides a reliable procedure for surveys of large population. in our hand 200 specimens were screened dur...
