BACKGROUND The SF-6D is a new single summary preference-based measure of health derived from the SF-36. Empirical work is required to determine what is the smallest change in SF-6D scores that can be regarded as important and meaningful for health professionals, patients and other stakeholders. OBJECTIVES To use anchor-based methods to determine the minimally important difference (MID) for th...

In this work, we introduce a novel learning environment for spatial data algorithms, SDA-TRAKLA2, which has been implemented on top of the TRAKLA2 system. Spatial data items are identified by a set of coordinates, such as x and y for two-dimensional spatial data. The spatial environment contains new visualizations for representing spatial data, and a number of new exercises that cover a variety...

Public policies must be devised in spite of profound uncertainties about the future. When there are many plausible scenarios for the future, it may well be impossible to construct any single static policy that will perform well in all of them. It is likely, however, that the uncertainties that confront planners will be resolved over the course of time by new information. Thus, policies should b...

We propose two packet merging policies; T-policy and N-policy, during data collections of small sized packets from a large number of sources in order to mitigate the effect of telemetry data traffic. The T-policy and N-policy are to merge small sized packets after a waiting time T and N packet arrivals, respectively. The effect of two packet merging policies on a given network is analyzed in te...

In rail transportation, there have been several attempts to determine the best routes for shipments (a number of cars with the same origin-destination) through the network. Shipments enter into several intermediate yards on their routes to separate and regroup shipments into new trains. Most of time, every entering into a yard includes excessive delay for shipments; therefore it is an ideal pla...

Streams are acyclic directed subgraphs of the logical $ow graph of a proof representing bundles of paths with the same origin and the same end. The notion of stream is used to describe the evolution of proofs during cut-elimination in purely algebraic terms. The algebraic and combinatorial properties of $ow graphs emerging from our analysis serve to elucidate logical phenomena. However, the ful...

A new software package, Browndye, is presented for simulating the diffusional encounter of two large biological molecules. It can be used to estimate second-order rate constants and encounter probabilities, and to explore reaction trajectories. Browndye builds upon previous knowledge and algorithms from software packages such as UHBD, SDA, and Macrodox, while implementing algorithms that scale ...
