A suboptimality test for two person zero sum Markov games

This paper presents a games version of the nonoptimality test given by Hastings for Markov decision processes. A pure action will be eliminated if compared to some randomized action it performs worse against any of the opponents possible actions

Furthering caring through nursing education

The nursing students’ main quest is for self actualization by attributing meaning to life through caring. To assist student nurses in this quest, the nurse educator needs to plan educational interventions according to an anthropological model that posits care and caring as innate human attributes. Further, the structural essence of what professional nursing caring entails should also be posited as a point of departure for curriculum planning. The author proposes such models. The main implications include that the nursing curriculum must increasingly attend to the emotional needs of nursing students. Curricular content and teaching strategies toward this goal are suggested

Verocytotoxine-producerende E.coli, risicofactoren en update Nederland

In dit rapport wordt een overzicht gepresenteerd betreffende het vóórkomen van VTEC in verschillende reservoirs, infectie incidentie, transmissieroutes, risicofactoren voor verspreiding door de voedselketen, diagnostiek, uitbraaktracering en (potentiële) interventiestrategieën. De focus is op de Nederlandse situatie en hoe die zich verhoudt met de Europese situati

Split-gate quantum point contacts with tunable channel length

We report on developing split-gate quantum point contacts (QPCs) that have a tunable length for the transport channel. The QPCs were realized in a GaAs/AlGaAs heterostructure with a two- dimensional electron gas (2DEG) below its surface. The conventional design uses 2 gate fingers on the wafer surface which deplete the 2DEG underneath when a negative gate voltage is applied, and this allows for tuning the width of the QPC channel. Our design has 6 gate fingers and this provides additional control over the form of the electrostatic potential that defines the channel. Our study is based on electrostatic simulations and experiments and the results show that we developed QPCs where the effective channel length can be tuned from about 200 nm to 600 nm. Length-tunable QPCs are important for studies of electron many-body effects because these phenomena show a nanoscale dependence on the dimensions of the QPC channel
