many countries are turning their attention to the use of explicit financial incentives to drive desired improvements in healthcare performance. however, we have only a weak evidence-base to inform policy in this area. the research challenge is to generate robust evidence on what financial incentives work, under what circumstances, for whom and with what intended and unintended consequences.

An ensemble contains a number of learners which are usually called base learners. The generalization ability of an ensemble is usually much stronger than that of base learners. Actually, ensemble learning is appealing because that it is able to boost weak learners which are slightly better than random guess to strong learners which can make very accurate predictions. So, “base learners” are als...

in this paper, hardness and tensile properties of welded zone of aluminum 1100 alloys by friction stir welding process was investigated and the effects of rotational and traverse speeds of tool on these parameters was studied. also the fracture cross-section of welded samples was investigated. according the results of this paper, the hardness of weld material is higher than base material and is...

A buffer is defined as a compound that in small concentrations can impart a resistance to large pH changes. Common buffers contain two substances, a conjugate base and a conjugate acid. There are acidic buffers that contain a weak acid and the salt of a weak acid (the conjugate base) and basic buffers that contain a weak base and the salt of a weak base (the conjugate acid). The combination of ...

The paper is devoted to a reverse-mathematical study of some well-known consequences Ramsey's theorem for pairs, focused on the chain-antichain principle CAC, ascending-descending sequence ADS, and Cohesive Ramsey Theorem pairs CRT22. We these principles over base theory RCA0⁎, which weaker than usual RCA0 considered in reverse mathematics that it allows only Δ10-induction as opposed Σ10-induct...

The effects of the functional groups and structures of two different resins, weak base/macroporous and strong base/gel type, Purolite A170 and Dowex 21K on the adsorption properties of Re(VII) ions were investigated experimentally and described by the isotherm, kinetic, and thermodynamic modeling. In this regard, four widely used adsorption isotherm models including Langmuir, Freundlich, Temkin...
