We consider the model for the distribution of a long homopolymer in a potential field. The typical shape of the polymer depends on the temperature parameter. We show that at a critical value of the temperature the transition occurs from a globular to an extended phase. For various values of the temperature, including those at or near the critical value, we consider the limiting behavior of the ...

In this regard, the Chronic Care Model or CCM was created to promote quality of care. The aim of this study was to examine whether establishment of chronic care model, with focus on diabetic patients, has led to clinically significant outcomes in Iran. Materials a...

In this paper the Dynamic User Equilibrium is formulated and solved as a fixed point problem in terms of time-continuous real valued temporal profiles of arc inflows and arc performances, where travel demand is specified both through a deterministic and a stochastic implicit path choice model. By extending to the dynamic case the concept of Network Loading Map, yielding arc flows for given dema...

this paper deals with continuous frames and continuous riesz bases. we introduce continuous riesz bases and give some equivalent conditions for a continuous frame to be a continuous riesz basis. it is certainly possible for a continuous frame to have only one dual. such a continuous frame is called a riesz-type frame [13]. we show that a continuous frame is riesz-type if and only if it is a con...

In this paper, we study metric structures with a nite number of metrics by extending the model theory developed by Ben Yaacov et al. in the monograph Model theory for metric structures. We rst de ne a metric structure with nitely many metrics, develop the theory of ultraproducts of multimetric structures, and prove some classical model-theoretic theorems about saturation for structures with mul...

AIMS To empirically validate a conceptual model of Clinical Nurse Leader integrated care delivery. BACKGROUND There is limited evidence of frontline care delivery models that consistently achieve quality patient outcomes. Clinical Nurse Leader integrated care delivery is a promising nursing model with a growing record of success. However, theoretical clarity is necessary to generate causal ev...
